approximately 24 psi (165 kPa). This tire pressure

is sufficiently low enough to turn on the TPMS

Warning Light. Driving the vehicle may cause the

tire pressure to rise to approximately 28 psi

(193 kPa), but the TPMS Warning Light will still be

on. In this situation, the TPMS Warning Light will

turn off only after the tires have been inflated to

the vehicle’s recommended cold tire pressure

value.

NOTE:



The TPMS is not intended to replace normal tire

care and maintenance, or to provide warning of

a tire failure or condition.



The TPMS should not be used as a tire pressure

gauge while adjusting your tire pressure.



Driving on a significantly underinflated tire

causes the tire to overheat and can lead to tire

failure. Underinflation also reduces fuel effi

ciency and tire tread life, and may affect the

vehicle’s handling and stopping ability.



The TPMS is not a substitute for proper tire

maintenance, and it is the driver’s responsibility

to maintain correct tire pressure using an accu

rate tire gauge, even if underinflation has not

reached the level to trigger illumination of the

TPMS Warning Light.



Seasonal temperature changes will affect tire

pressure, and the TPMS will monitor the actual

tire pressure in the tire.

The TPMS uses wireless technology with wheel

rim-mounted electronic sensors to monitor tire

pressure levels. Sensors, mounted to each wheel

as part of the valve stem, transmit tire pressure

readings to the receiver module.

Tire Pressure Monitoring System Display

NOTE:

It is particularly important for you to regularly check

the tire pressure in all of your tires and to maintain

the proper pressure

page 321.

The Tire Pressure Monitoring System (TPMS)

consists of the following components:



Receiver module



Four Tire Pressure Monitoring System sensors



Various Tire Pressure Monitoring System

Messages, which display in the instrument

cluster, and a graphic displaying tire pressures



TPMS Warning Light

CAUTION!



The TPMS has been optimized for the original

equipment tires and wheels. TPMS pressures

and warnings have been established for the

tire size equipped on your vehicle. Undesir

able system operation or sensor damage may

result when using replacement equipment

that is not of the same size, type, and/or style.

The TPMS sensor is not designed for use on

aftermarket wheels and may contribute to a

poor overall system performance or sensor

damage. Customers are encouraged to use

OEM wheels to ensure proper TPMS feature

operation.



Using aftermarket tire sealants may cause the

Tire Pressure Monitoring System (TPMS) sensor

to become inoperable. After using an after

market tire sealant it is recommended that you

take your vehicle to an authorized dealership to

have your sensor function checked.



After inspecting or adjusting the tire pressure,

always reinstall the valve stem cap. This will

prevent moisture and dirt from entering the

valve stem, which could damage the Tire Pres

sure Monitoring System sensor.

CAUTION!

Tire Pressure Monitoring System Low

Pressure Warnings

The TPMS Warning Light will illuminate in

the instrument cluster, and an audible

chime will be activated, when one or

more of the four active road tire

pressures are low. In addition, the instrument

cluster will display an "Inflate to XX" message and

a graphic display of the pressure value(s) with the

low tire(s) in a different color.

NOTE:

Your system can be set to display pressure units in

PSI, BAR, or kPa.

Low Tire Pressure Monitoring System Display

Should a low tire condition occur on any of the four

active road tire(s), you should stop as soon as

possible, and inflate the low tire(s) that is in a

different color on the graphic display to the

vehicle’s recommended cold tire pressure

displayed in the “Inflate to XX” message.

NOTE:

When filling warm tires, the tire pressure may need

to be increased up to an additional 4 psi (28 kPa)

above the recommended cold placard pressure in

order to turn the TPMS Warning Light off.
The system will automatically update, the graphic

display of the pressure value(s) will return to its

original color and the TPMS Warning Light will

extinguish once the updated tire pressure(s) have

been received. The vehicle may need to be driven

for up to 20 minutes above 15 mph (24 km/h) to

receive this information.

Service TPMS Warning

The Tire Pressure Monitoring System Warning Light

will flash on and off for 75 seconds, and remain on

solid when a system fault is detected. The system

fault will also sound a chime. The instrument

cluster display will display a “SERVICE TPM

SYSTEM” message for a minimum of five seconds.

This message is then followed by a graphic display,

with “- -“ in place of the pressure value(s),

indicating which Tire Pressure Monitoring System

sensor(s) is not being received.
If the ignition switch is cycled, this sequence will

repeat, providing the system fault still exists. If the

system fault no longer exists, the Tire Pressure

Monitoring System Warning Light will no longer

flash, the "SERVICE TPM SYSTEM" message will

not be present, and a pressure value will be

displayed instead of dashes. A system fault can

occur by any of the following:



Jamming due to electronic devices or driving

next to facilities emitting the same Radio

Frequencies as the TPMS sensors



Lots of snow or ice around the wheels or

wheel housings



Using tire chains on the vehicle



Using wheels/tires not equipped with

TPMS sensors

NOTE:

There is no Tire Pressure Monitoring System

sensor in the spare tire. The TPMS will not be able

to monitor the tire pressure. If you install the spare

tire in place of a road tire that has a pressure below

the low-pressure warning limit, upon the next

ignition switch cycle, the Tire Pressure Monitoring

System Warning Light will remain on, a chime will

sound, and the instrument cluster display will still

display a pressure value in the different color

graphic display and an “Inflate to XX” message will

be displayed. After driving the vehicle for up to

20 minutes above 15 mph (24 km/h), the Tire

Pressure Monitoring System Warning Light will

flash on and off for 75 seconds and then remain on

solid. In addition, the instrument cluster display

will display a “SERVICE TPM SYSTEM" message for

204

SAFETY

five seconds and then display dashes (- -) in place

of the pressure value. For each subsequent

ignition switch cycle, a chime will sound, the Tire

Pressure Monitoring System Warning Light will

flash on and off for 75 seconds and then remain on

solid, and the instrument cluster display will

display a "SERVICE TPM SYSTEM" message for five

seconds and then display dashes (- -) in place of

the pressure value. Once you repair or replace the

original road tire, and reinstall it on the vehicle in

place of the spare tire, the TPMS will update auto

matically.
In addition, the Tire Pressure Monitoring System

Warning Light will turn off and the graphic in the

instrument cluster display will display a new

pressure value instead of dashes (- -), as long as no

tire pressure is below the low-pressure warning

limit in any of the four active road tires. The vehicle

may need to be driven for up to 20 minutes above

15 mph (24 km/h) in order for the TPMS to receive

this information.

TPMS Deactivation — If Equipped

The Tire Pressure Monitoring System (TPMS) can

be deactivated if replacing all four wheel and tire

assemblies (road tires) with wheel and tire

assemblies that do not have TPMS sensors, such

as when installing winter wheel and tire

assemblies on your vehicle.

To deactivate the TPMS, first, replace all four wheel

and tire assemblies (road tires) with tires not

equipped with TPMS sensors. Then, drive the

vehicle for 20 minutes above 15 mph (24 km/h).

The TPMS will chime, the TPMS Warning Light will

flash on and off for 75 seconds and then remain

on. The instrument cluster will display the

“SERVICE TPM SYSTEM” message and then

display dashes (--) in place of the pressure values.
Beginning with the next ignition cycle, the TPMS

will no longer chime or display the “SERVICE TPM

SYSTEM” message in the instrument cluster but

dashes (--) will remain in place of the pressure

values.
To reactivate the TPMS, replace all four wheel and

tire assemblies (road tires) with tires equipped with

TPM sensors. Then, drive the vehicle for up to

20 minutes above 15 mph (24 km/h). The TPMS

will chime, the TPMS Warning Light will flash on

and off for 75 seconds and then turn off. The

instrument cluster will display the “SERVICE TPM

SYSTEM” message and then display pressure

values in place of the dashes. On the next ignition

cycle the "SERVICE TPM SYSTEM" message will no

longer be displayed as long as no system fault

exists.

RECAUTIONS

Please pay close attention to the information in

this section. It tells you how to use your restraint

system properly, to keep you and your passengers

as safe as possible.
Here are some simple steps you can take to

minimize the risk of harm from a deploying air bag:
1. Children 12 years old and under should

always ride buckled up in the rear seat of a

vehicle with a rear seat.

SAFETY

205

2. A child who is not big enough to wear the

vehicle seat belt properly must be secured in

the appropriate child restraint or

belt-positioning booster seat in a rear seating

position

page 221.

3. If a child from 2 to 12 years old (not in a

rear-facing child restraint) must ride in the

front passenger seat, move the seat as far

back as possible and use the proper child

restraint

page 221.

4. Never allow children to slide the shoulder belt

behind them or under their arm.

5. You should read the instructions provided with

your child restraint to make sure that you are

using it properly.

6. All occupants should always wear their lap and

shoulder belts properly.

7. The driver and front passenger seats should

be moved back as far as practical to allow the

front air bags room to inflate.

8. Do not lean against the door or window. If your

vehicle has side air bags, and deployment

occurs, the side air bags will inflate forcefully

into the space between occupants and the

door and occupants could be injured.

9. If the air bag system in this vehicle needs to be

modified to accommodate a disabled person,

see

page 318 for customer service contact

information.

EAT

ELT

YSTEMS

Buckle up even though you are an excellent driver,

even on short trips. Someone on the road may be

a poor driver and could cause a collision that

includes you. This can happen far away from home

or on your own street.
Research has shown that seat belts save lives, and

they can reduce the seriousness of injuries in a

collision. Some of the worst injuries happen when

people are thrown from the vehicle. Seat belts

reduce the possibility of ejection and the risk of

injury caused by striking the inside of the vehicle.

Everyone in a motor vehicle should be belted at all

times.

Enhanced Seat Belt Use Reminder System

(BeltAlert)

Driver And Passenger BeltAlert — If Equipped

BeltAlert is a feature intended to remind

the driver and outboard front seat

passenger (if equipped with outboard

front passenger seat BeltAlert) to buckle

their seat belts. The BeltAlert feature is active

whenever the ignition switch is in the START or ON/

RUN position.
Initial Indication
If the driver is unbuckled when the ignition switch

is first in the START or ON/RUN position, a chime

will signal for a few seconds. If the driver or

outboard front seat passenger (if equipped with

outboard front passenger seat BeltAlert) is

unbuckled when the ignition switch is first in the

START or ON/RUN position the Seat Belt Reminder

Light will turn on and remain on until both outboard

front seat belts are buckled. The outboard front

passenger seat BeltAlert is not active when an

outboard front passenger seat is unoccupied.
BeltAlert Warning Sequence
The BeltAlert warning sequence is activated when

the vehicle is moving above a specified vehicle

speed range and the driver or outboard front seat

passenger is unbuckled (if equipped with outboard

front passenger seat BeltAlert) (the outboard front

passenger seat BeltAlert is not active when the

WARNING!



Never place a rear-facing child restraint in

front of an air bag. A deploying passenger

front air bag can cause death or serious injury

to a child 12 years or younger, including a

child in a rear-facing child restraint.



Never install a rear-facing child restraint in the

front seat of a vehicle. Only use a rear-facing

child restraint in the rear seat. If the vehicle

does not have a rear seat, do not transport a

rear-facing child restraint in that vehicle.

SAFETY

(Continued)

outboard front passenger seat is unoccupied). The

BeltAlert warning sequence starts by blinking the

Seat Belt Reminder Light and sounding an

intermittent chime. Once the BeltAlert warning

sequence has completed, the Seat Belt Reminder

Light will remain on until the seat belts are

buckled. The BeltAlert warning sequence may

repeat based on vehicle speed until the driver and

occupied outboard front seat passenger seat belts

are buckled. The driver should instruct all

occupants to buckle their seat belts.
Change Of Status
If the driver or outboard front seat passenger (if

equipped with outboard front passenger seat

BeltAlert) unbuckles their seat belt while the

vehicle is traveling, the BeltAlert warning sequence

will begin until the seat belts are buckled again.
The outboard front passenger seat BeltAlert is not

active when the outboard front passenger seat is

unoccupied. BeltAlert may be triggered when an

animal or other items are placed on the outboard

front passenger seat or when the seat is folded flat

(if equipped). It is recommended that pets be

restrained in the rear seat (if equipped) in pet

harnesses or pet carriers that are secured by seat

belts, and cargo is properly stowed.
BeltAlert can be activated or deactivated by an

authorized dealer. FCA US LLC does not

recommend deactivating BeltAlert.

NOTE:

If BeltAlert has been deactivated and the driver or

outboard front seat passenger (if equipped with

outboard front passenger seat BeltAlert) is

unbuckled the Seat Belt Reminder Light will turn

on and remain on until the driver and outboard

front seat passenger seat belts are buckled.

Lap/Shoulder Belts

All seating positions in your vehicle are equipped

with lap/shoulder belts.
The seat belt webbing retractor will lock only during

very sudden stops or collisions. This feature allows

the shoulder part of the seat belt to move freely

with you under normal conditions. However, in a

collision the seat belt will lock and reduce your risk

of striking the inside of the vehicle or being thrown

out of the vehicle.

WARNING!



Relying on the air bags alone could lead to

more severe injuries in a collision. The air

bags work with your seat belt to restrain you

properly. In some collisions, the air bags won’t

deploy at all. Always wear your seat belt even

though you have air bags.



In a collision, you and your passengers can

suffer much greater injuries if you are not

properly buckled up. You can strike the inte

rior of your vehicle or other passengers, or you

can be thrown out of the vehicle. Always be

sure you and others in your vehicle are

buckled up properly.



It is dangerous to ride in a cargo area, inside

or outside of a vehicle. In a collision, people

riding in these areas are more likely to be seri

ously injured or killed.



Do not allow people to ride in any area of your

vehicle that is not equipped with seats and

seat belts.



Be sure everyone in your vehicle is in a seat

and using a seat belt properly. Occupants,

including the driver, should always wear their

seat belts whether or not an air bag is also

provided at their seating position to minimize

the risk of severe injury or death in the event

of a crash.

WARNING!

Lap/Shoulder Belt Operating Instructions

1. Enter the vehicle and close the door. Sit back

and adjust the seat.

2. The seat belt latch plate is above the back of

the front seat, and next to your arm in the rear

seat (for vehicles equipped with a rear seat).

Grab the latch plate and pull out the seat belt.

Slide the latch plate up the webbing as far as

necessary to allow the seat belt to go around

your lap.



Wearing your seat belt incorrectly could make

your injuries in a collision much worse. You

might suffer internal injuries, or you could

even slide out of the seat belt. Follow these

instructions to wear your seat belt safely and

to keep your passengers safe, too.



Two people should never be belted into a

single seat belt. People belted together can

crash into one another in a collision, hurting

one another badly. Never use a lap/shoulder

belt or a lap belt for more than one person, no

matter what their size.

WARNING!



A lap belt worn too high can increase the risk

of injury in a collision. The seat belt forces

won’t be at the strong hip and pelvic bones,

but across your abdomen. Always wear the lap

part of your seat belt as low as possible and

keep it snug.



A twisted seat belt may not protect you prop

erly. In a collision, it could even cut into you.

Be sure the seat belt is flat against your body,

without twists. If you can’t straighten a seat

belt in your vehicle, take it to an authorized

dealer immediately and have it fixed.

WARNING!



A seat belt that is buckled into the wrong buckle

will not protect you properly. The lap portion

could ride too high on your body, possibly

causing internal injuries. Always buckle your

seat belt into the buckle nearest you.



A seat belt that is too loose will not protect you

properly. In a sudden stop, you could move too

far forward, increasing the possibility of injury.

Wear your seat belt snugly.



A seat belt that is worn under your arm is

dangerous. Your body could strike the inside

surfaces of the vehicle in a collision,

increasing head and neck injury. A seat belt

worn under the arm can cause internal inju

ries. Ribs aren’t as strong as shoulder bones.

Wear the seat belt over your shoulder so that

your strongest bones will take the force in a

collision.



A shoulder belt placed behind you will not

protect you from injury during a collision. You

are more likely to hit your head in a collision if

you do not wear your shoulder belt. The lap

and shoulder belt are meant to be used

together.

WARNING!



A frayed or torn seat belt could rip apart in a

collision and leave you with no protection.

Inspect the seat belt system periodically,

checking for cuts, frays, or loose parts.

Damaged parts must be replaced immedi

ately. Do not disassemble or modify the seat

belt system. If your vehicle is involved in a

collision, or if you have questions regarding

seat belt or retractor conditions, take your

vehicle to an authorized FCA dealer or autho

rized FCA Certified Collision Care Program

facility for inspection.

WARNING!

208

SAFETY

Pulling Out The Latch Plate

3. When the seat belt is long enough to fit, insert

the latch plate into the buckle until you hear a

“click.”

Inserting Latch Plate Into Buckle

4. Position the lap belt so that it is snug and lies

low across your hips, below your abdomen. To

remove slack in the lap belt portion, pull up on

the shoulder belt. To loosen the lap belt if it is

too tight, tilt the latch plate and pull on the lap

belt. A snug seat belt reduces the risk of sliding

under the seat belt in a collision.

Positioning The Lap Belt

5. Position the shoulder belt across the shoulder

and chest with minimal, if any slack so that it

is comfortable and not resting on your neck.

The retractor will withdraw any slack in the

shoulder belt.

6. To release the seat belt, push the red button

on the buckle. The seat belt will automatically

retract to its stowed position. If necessary,

slide the latch plate down the webbing to allow

the seat belt to retract fully.

Lap/Shoulder Belt Untwisting Procedure

Use the following procedure to untwist a twisted

lap/shoulder belt.
1. Position the latch plate as close as possible to

the anchor point.

2. At about 6 to 12 inches (15 to 30 cm) above

the latch plate, grab and twist the seat belt

webbing 180 degrees to create a fold that

begins immediately above the latch plate.

3. Slide the latch plate upward over the folded

webbing. The folded webbing must enter the

slot at the top of the latch plate.

4. Continue to slide the latch plate up until it

clears the folded webbing and the seat belt is

no longer twisted.

SAFETY

209

Adjustable Upper Shoulder Belt Anchorage

In the driver and outboard front passenger seats,

the top of the shoulder belt can be adjusted

upward or downward to position the seat belt away

from your neck. Push or squeeze the anchorage

button to release the anchorage, and move it up or

down to the position that serves you best.

Adjustable Anchorage

As a guide, if you are shorter than average, you will

prefer the shoulder belt anchorage in a lower

position, and if you are taller than average, you will

prefer the shoulder belt anchorage in a higher

position. After you release the anchorage button,

try to move it up or down to make sure that it is

locked in position.

NOTE:

The adjustable upper shoulder belt anchorage is

equipped with an Easy Up feature. This feature

allows the shoulder belt anchorage to be adjusted

in the upward position without pushing or

squeezing the release button. To verify the

shoulder belt anchorage is latched, pull downward

on the shoulder belt anchorage until it is locked

into position.

Seat Belt Extender

If a seat belt is not long enough to fit properly, even

when the webbing is fully extended and the

adjustable upper shoulder belt anchorage (if

equipped) is in its lowest position, an authorized

dealer can provide you with a Seat Belt Extender.

The Seat Belt Extender should be used only if the

existing seat belt is not long enough. When the

Seat Belt Extender is not required for a different

occupant, it must be removed.

WARNING!



Wearing your seat belt incorrectly could make

your injuries in a collision much worse. You

might suffer internal injuries, or you could

even slide out of the seat belt. Follow these

instructions to wear your seat belt safely and

to keep your passengers safe, too.



Position the shoulder belt across the shoulder

and chest with minimal, if any slack so that it

is comfortable and not resting on your neck.

The retractor will withdraw any slack in the

shoulder belt.



Misadjustment of the seat belt could reduce

the effectiveness of the safety belt in a crash.



Always make all seat belt height adjustments

when the vehicle is stationary.

WARNING!



ONLY use a Seat Belt Extender if it is physically

required in order to properly fit the original

seat belt system. DO NOT USE the Seat Belt

Extender if, when worn, the distance between

the front edge of the Seat Belt Extender

buckle and the center of the occupant’s body

is LESS than 6 inches.



Using a Seat Belt Extender when not needed

can increase the risk of serious injury or death

in a collision. Only use the Seat Belt Extender

when the lap belt is not long enough and only

use in the recommended seating positions.

Remove and store the Seat Belt Extender

when not needed.

210

SAFETY

Seat Belts And Pregnant Women

Seat belts must be worn by all occupants including

pregnant women: the risk of injury in the event of

an accident is reduced for the mother and the

unborn child if they are wearing a seat belt.
Position the lap belt snug and low below the

abdomen and across the strong bones of the hips.

Place the shoulder belt across the chest and away

from the neck. Never place the shoulder belt

behind the back or under the arm.

Seat Belt Pretensioner

The front outboard seat belt system is equipped

with pretensioning devices that are designed to

remove slack from the seat belt in the event of a

collision. These devices may improve the

performance of the seat belt by removing slack

from the seat belt early in a collision. Pretensioners

work for all size occupants, including those in child

restraints.

NOTE:

These devices are not a substitute for proper seat

belt placement by the occupant. The seat belt still

must be worn snugly and positioned properly.
The pretensioners are triggered by the Occupant

Restraint Controller (ORC). Like the air bags, the

pretensioners are single use items. A deployed

pretensioner or a deployed air bag must be

replaced immediately.

Energy Management Feature

The front outboard seat belt system is equipped

with an Energy Management feature that may help

further reduce the risk of injury in the event of a

collision. The seat belt system has a retractor

assembly that is designed to release webbing in a

controlled manner.

Switchable Automatic Locking Retractor

(ALR)

The seat belts in the passenger seating positions

are equipped with a Switchable Automatic Locking

Retractor (ALR) which is used to secure a child

restraint system

page 221.

The figure below illustrates the locking feature for

each seating position.

Automatic Locking Retractor (ALR) Locations

If the passenger seating position is equipped with

an ALR and is being used for normal usage, only

pull the seat belt webbing out far enough to

comfortably wrap around the occupant’s

mid-section so as to not activate the ALR. If the ALR

is activated, you will hear a clicking sound as the

seat belt retracts. Allow the webbing to retract

completely in this case and then carefully pull out

only the amount of webbing necessary to

comfortably wrap around the occupant’s

mid-section. Slide the latch plate into the buckle

until you hear a "click."
In Automatic Locking Mode, the shoulder belt is

automatically pre-locked. The seat belt will still

retract to remove any slack in the shoulder belt.

Use the Automatic Locking Mode anytime a child

restraint is installed in a seating position that has

SAFETY

211

a seat belt with this feature. Children 12 years old

and under should always be properly restrained in

the rear seat of a vehicle with a rear seat.

How To Engage The Automatic Locking Mode
1. Buckle the combination lap and shoulder

belt.

2. Grab the shoulder portion and pull downward

until the entire seat belt is extracted.

3. Allow the seat belt to retract. As the seat belt

retracts, you will hear a clicking sound. This

indicates the seat belt is now in the Automatic

Locking Mode.

How To Disengage The Automatic Locking Mode
Unbuckle the combination lap/shoulder belt and

allow it to retract completely to disengage the

Automatic Locking Mode and activate the vehicle

sensitive (emergency) locking mode.

Supplemental Active Head Restraints

(AHR)

These head restraints are passive, deployable

components, and vehicles with this equipment

cannot be readily identified by any markings, only

through visual inspection of the head restraint. The

head restraint will be split in two halves, with the

front half being soft foam and trim, the back half

being decorative plastic.
How The Active Head Restraints (AHR) Work
The Occupant Restraint Controller (ORC)

determines whether the severity or type of rear

impact will require the Active Head Restraints

(AHR) to deploy. If a rear impact requires

deployment, both the driver and front passenger

seat AHRs will be deployed.
When AHRs deploy during a rear impact, the front

half of the head restraint extends forward to

minimize the gap between the back of the

occupant’s head and the AHR. This system is

designed to help prevent or reduce the extent of

injuries to the driver and front passenger in certain

types of rear impacts.

NOTE:

The Active Head Restraints (AHR) may or may not

deploy in the event of a front or side impact.

However, if during a front impact, a secondary rear

impact occurs, the AHR may deploy based on the

severity and type of the impact.

WARNING!



Never place a rear-facing child restraint in

front of an air bag. A deploying passenger

front air bag can cause death or serious injury

to a child 12 years or younger, including a

child in a rear-facing child restraint.



Never install a rear-facing child restraint in the

front seat of a vehicle. Only use a rear-facing

child restraint in the rear seat. If the vehicle

does not have a rear seat, do not transport a

rear-facing child restraint in that vehicle.

WARNING!



The seat belt assembly must be replaced if the

switchable Automatic Locking Retractor (ALR)

feature or any other seat belt function is not

working properly when checked according to

the procedures in the Service Manual.



Failure to replace the seat belt assembly

could increase the risk of injury in collisions.



Do not use the Automatic Locking Mode to

restrain occupants who are wearing the seat

belt or children who are using booster seats.

The locked mode is only used to install

rear-facing or forward-facing child restraints

that have a harness for restraining the child.

Resetting Active Head Restraints (AHR)

Active Head Restraint (AHR) Deployed

If the Active Head Restraints are triggered during a

collision, the front half of the head restraint will be

extended forward and separated from the rear half

of the head restraint (See Image). Do not drive your

vehicle after the AHRs have deployed. The head

restraint must be reset into the original position to

best protect the occupant for all types of collisions.

An authorized FCA US LLC dealer must reset the

AHRs on the driver’s and front passenger’s seat

before driving. Personally attempting to reset the

AHRs may result in damage to the AHRs that could

impair their function.

WARNING!



All occupants, including the driver, should not

operate a vehicle or sit in a vehicle’s seat until

the head restraints are placed in their proper

positions in order to minimize the risk of neck

injury in the event of a collision.



Do not place items over the top of the Active

Head Restraint, such as coats, seat covers or

portable DVD players. These items may inter

fere with the operation of the Active Head

Restraint in the event of a collision and could

result in serious injury or death.



Active Head Restraints may be deployed if

they are struck by an object such as a hand,

foot or loose cargo. To avoid accidental

deployment of the Active Head Restraint,

ensure that all cargo is secured, as loose

cargo could contact the Active Head Restraint

during sudden stops. Failure to follow this

warning could cause personal injury if the

Active Head Restraint is deployed.

WARNING!

Air Bag Warning Light

The Occupant Restraint Controller (ORC)

monitors the readiness of the electronic

parts of the air bag system whenever the

ignition switch is in the START or ON/RUN

position. If the ignition switch is in the OFF position

or in the ACC position, the air bag system is not on

and the air bags will not inflate.
The ORC contains a backup power supply system

that may deploy the air bag system even if the

battery loses power or it becomes disconnected

prior to deployment.
The ORC turns on the Air Bag Warning Light in the

instrument panel for approximately four to eight

seconds for a self-check when the ignition switch is

first in the ON/RUN position. After the self-check,

the Air Bag Warning Light will turn off. If the ORC

detects a malfunction in any part of the system, it

turns on the Air Bag Warning Light, either

momentarily or continuously. A single chime will

sound to alert you if the light comes on again after

initial startup.
The ORC also includes diagnostics that will

illuminate the instrument panel Air Bag Warning

Light if a malfunction is detected that could affect

the air bag system. The diagnostics also record the

nature of the malfunction. While the air bag system

is designed to be maintenance free, if any of the

following occurs, have an authorized dealer

service the air bag system immediately.



The Air Bag Warning Light does not come on

during the four to eight seconds when the igni

tion switch is first in the ON/RUN position.



The Air Bag Warning Light remains on after the

four to eight-second interval.



The Air Bag Warning Light comes on intermit

tently or remains on while driving.

NOTE:

If the speedometer, tachometer, or any engine

related gauges are not working, the Occupant

Restraint Controller (ORC) may also be disabled. In

this condition the air bags may not be ready to

inflate for your protection. Have an authorized

dealer service the air bag system immediately.

WARNING!

Ignoring the Air Bag Warning Light in your

instrument panel could mean you won’t have the

air bag system to protect you in a collision. If the

light does not come on as a bulb check when the

ignition is first turned on, stays on after you start

the vehicle, or if it comes on as you drive, have

an authorized dealer service the air bag system

immediately.

Front Air Bags

This vehicle has front air bags and lap/shoulder

belts for both the driver and front passenger. The

front air bags are a supplement to the seat belt

restraint systems. The driver front air bag is

mounted in the center of the steering wheel. The

passenger front air bag is mounted in the

instrument panel, above the glove compartment.

The words “SRS AIRBAG” or “AIRBAG” are

embossed on the air bag covers.

Front Air Bag/Knee Bolster Locations

Driver And Passenger Front Air Bag

Features

The Advanced Front Air Bag system has multistage

driver and front passenger air bags. This system

provides output appropriate to the severity and

type of collision as determined by the Occupant

Restraint Controller (ORC), which may receive

information from the front impact sensors (if

equipped) or other system components.
The first stage inflator is triggered immediately

during an impact that requires air bag deployment.

A low energy output is used in less severe

collisions. A higher energy output is used for more

severe collisions.

2 — Driver Knee Impact Bolster/Supplemental

Knee Air Bag
3 — Passenger Knee Impact Bolster

WARNING!



Being too close to the steering wheel or instru

ment panel during front air bag deployment

could cause serious injury, including death. Air

bags need room to inflate. Sit back, comfort

ably extending your arms to reach the steering

wheel or instrument panel.



Never place a rear-facing child restraint in

front of an air bag. A deploying passenger

front air bag can cause death or serious injury

to a child 12 years or younger, including a

child in a rear-facing child restraint.



Never install a rear-facing child restraint in the

front seat of a vehicle. Only use a rear-facing

child restraint in the rear seat. If the vehicle

does not have a rear seat, do not transport a

rear-facing child restraint in that vehicle.

WARNING!

SAFETY

215

This vehicle may be equipped with a driver and/or

front passenger seat belt buckle switch that

detects whether the driver or front passenger seat

belt is buckled. The seat belt buckle switch may

adjust the inflation rate of the Advanced Front Air

Bags.

Front Air Bag Operation

Front Air Bags are designed to provide additional

protection by supplementing the seat belts. Front

air bags are not expected to reduce the risk of

injury in rear, side, or rollover collisions. The front

air bags will not deploy in all frontal collisions,

including some that may produce substantial

vehicle damage — for example, some pole

collisions, truck underrides, and angle offset

collisions.
On the other hand, depending on the type and

location of impact, front air bags may deploy in

crashes with little vehicle front-end damage but

that produce a severe initial deceleration.
Because air bag sensors measure vehicle

deceleration over time, vehicle speed and damage

by themselves are not good indicators of whether

or not an air bag should have deployed.
Seat belts are necessary for your protection in all

collisions, and also are needed to help keep you in

position, away from an inflating air bag.
When the Occupant Restraint Controller (ORC)

detects a collision requiring the front air bags, it

signals the inflator units. A large quantity of

non-toxic gas is generated to inflate the front air

bags.

The steering wheel hub trim cover and the upper

passenger side of the instrument panel separate

and fold out of the way as the air bags inflate to

their full size. The front air bags fully inflate in less

time than it takes to blink your eyes. The front air

bags then quickly deflate while helping to restrain

the driver and front passenger.

Knee Impact Bolsters

The Knee Impact Bolsters help protect the knees

of the driver and front passenger, and position the

front occupants for improved interaction with the

front air bags.

Supplemental Driver Knee Air Bag

This vehicle is equipped with a Supplemental

Driver Knee Air Bag mounted in the instrument

panel below the steering column. The

Supplemental Driver Knee Air Bag provides

enhanced protection during a frontal impact by

working together with the seat belts,

pretensioners, and front air bags.

WARNING!



No objects should be placed over or near the

air bag on the instrument panel or steering

wheel because any such objects could cause

harm if the vehicle is in a collision severe

enough to cause the air bag to inflate.



Do not put anything on or around the air bag

covers or attempt to open them manually. You

may damage the air bags and you could be

injured because the air bags may no longer be

functional. The protective covers for the air

bag cushions are designed to open only when

the air bags are inflating.



Relying on the air bags alone could lead to

more severe injuries in a collision. The air

bags work with your seat belt to restrain you

properly. In some collisions, air bags won’t

deploy at all. Always wear your seat belts even

though you have air bags.

WARNING!



Do not drill, cut, or tamper with the knee

impact bolsters in any way.



Do not mount any accessories to the knee

impact bolsters such as alarm lights, stereos,

citizen band radios, etc.

SAFETY

Supplemental Side Air Bags

Supplemental Seat-Mounted Side Air Bags (SABs)
This vehicle is equipped with Supplemental

Seat-Mounted Side Air Bags (SABs).
Supplemental Seat-Mounted Side Air Bags (SABs)

are located in the outboard side of the front seats.

The SABs are marked with “SRS AIRBAG” or

“AIRBAG” on a label or on the seat trim on the

outboard side of the seats.
The SABs may help to reduce the risk of occupant

injury during certain side impacts, in addition to

the injury reduction potential provided by the seat

belts and body structure.

Front Supplemental Seat-Mounted Side Air Bag Label

When the SAB deploys, it opens the seam on the

outboard side of the seatback’s trim cover. The

inflating SAB deploys through the seat seam into

the space between the occupant and the door. The

SAB moves at a very high speed and with such a

high force that it could injure occupants if they are

not seated properly, or if items are positioned in

the area where the SAB inflates. Children are at an

even greater risk of injury from a deploying air bag.

Supplemental Side Air Bag Inflatable Curtains

(SABICs)
This vehicle is equipped with Supplemental Side

Air Bag Inflatable Curtains (SABICs).
Supplemental Side Air Bag Inflatable Curtains

(SABICs) are located above the side windows. The

trim covering the SABICs is labeled “SRS AIRBAG”

or “AIRBAG.”

Supplemental Side Air Bag Inflatable Curtain (SABIC)

Label Location

SABICs may help reduce the risk of head and other

injuries to front and rear seat outboard occupants

in certain side impacts, in addition to the injury

reduction potential provided by the seat belts and

body structure.
The SABIC deploys downward, covering the side

windows. An inflating SABIC pushes the outside

edge of the headliner out of the way and covers the

window. The SABICs inflate with enough force to

injure occupants if they are not belted and seated

properly, or if items are positioned in the area

where the SABICs inflate. Children are at an even

greater risk of injury from a deploying air bag.

WARNING!

Do not use accessory seat covers or place

objects between you and the Side Air Bags; the

performance could be adversely affected and/or

objects could be pushed into you, causing

serious injury.

SAFETY

217

(Continued)

The SABICs may help reduce the risk of partial or

complete ejection of vehicle occupants through

side windows in certain side impact events.

Side Impacts
The Side Air Bags are designed to activate in

certain side impacts. The Occupant Restraint

Controller (ORC) determines whether the

deployment of the Side Air Bags in a particular

impact event is appropriate, based on the severity

and type of collision. The side impact sensors aid

the ORC in determining the appropriate response

to impact events. The system is calibrated to

deploy the Side Air Bags on the impact side of the

vehicle during impacts that require Side Air Bag

occupant protection. In side impacts, the Side Air

Bags deploy independently; a left side impact

deploys the left Side Air Bags only and a right-side

impact deploys the right Side Air Bags only. Vehicle

damage by itself is not a good indicator of whether

or not Side Air Bags should have deployed.
The Side Air Bags will not deploy in all side

collisions, including some collisions at certain

angles, or some side collisions that do not impact

the area of the passenger compartment. The Side

Air Bags may deploy during angled or offset frontal

collisions where the front air bags deploy.
Side Air Bags are a supplement to the seat belt

restraint system. Side Air Bags deploy in less time

than it takes to blink your eyes.

WARNING!



Do not mount equipment, or stack luggage or

other cargo up high enough to block the

deployment of the SABICs. The trim covering

above the side windows where the SABIC and

its deployment path are located should

remain free from any obstructions.



In order for the SABICs to work as intended, do

not install any accessory items in your vehicle

which could alter the roof. Do not add an after

market sunroof to your vehicle. Do not add

roof racks that require permanent attach

ments (bolts or screws) for installation on the

vehicle roof. Do not drill into the roof of the

vehicle for any reason.

WARNING!



Occupants, including children, who are up

against or very close to Side Air Bags can be

seriously injured or killed. Occupants,

including children, should never lean on or

sleep against the door, side windows, or area

where the side air bags inflate, even if they are

in an infant or child restraint.



Seat belts (and child restraints where appro

priate) are necessary for your protection in all

collisions. They also help keep you in position,

away from an inflating Side Air Bag. To get the

best protection from the Side Air Bags, occu

pants must wear their seat belts properly and

sit upright with their backs against the seats.

Children must be properly restrained in a child

restraint or booster seat that is appropriate for

the size of the child.

WARNING!



Side Air Bags need room to inflate. Do not lean

against the door or window. Sit upright in the

center of the seat.



Being too close to the Side Air Bags during

deployment could cause you to be severely

injured or killed.



Relying on the Side Air Bags alone could lead

to more severe injuries in a collision. The Side

Air Bags work with your seat belt to restrain

you properly. In some collisions, Side Air Bags

won’t deploy at all. Always wear your seat belt

even though you have Side Air Bags.
