SAFETY

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

TPMS 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.

Tire Fill Alert

This feature notifies the user when the placard tire

pressure is attained while inflating or deflating the

tire.
The customer may choose to disable or enable the

Tire Fill Alert feature in the apps menu of the

Uconnect system.
NOTE:



The Tire Fill Alert system will only support

inflating or deflating one tire at a time. The user

is required to wait until the hazard lights STOP

flashing or 26-30 seconds after the desired

pressure is achieved in one wheel before

switching to another.



The Tire Fill Alert feature cannot be entered if an

existing TPMS fault is set to “active” or if the

system is in deactivation mode (if equipped).

The system will be activated when the system

detects an increase in tire pressure while filling the

tire. The ignition must be in the ON/RUN mode with

the transmission in PARK for vehicles equipped

with an automatic transmission. For vehicles

equipped with a manual transmission, the parking

brake must be applied.
NOTE:

It is not required to have the engine running to

enter Tire Fill Alert mode.
The hazard lamps will come on to confirm the

vehicle is in Tire Fill Alert mode. If the hazard lamps

do not come on while inflating the tire, the Tire

Pressure Monitoring System sensor may be in an

inoperative position, preventing the TPMS sensor

signal from being received. In this case, the vehicle

may need to be moved slightly forward or

backward.
When Tire Fill Alert mode is entered, the tire

pressure display screen will be displayed in the

instrument cluster.

Operation:



The horn will chirp once to let the user know

when to stop filling the tire, when it reaches

recommended pressure.



The horn will chirp three times if the tire is over

filled and will continue to chirp every five

seconds if the user continues to inflate the tire.



The horn will chirp once again when enough air

is let out to reach proper inflation level.



The horn will also chirp three times if the tire is

then underinflated and will continue to chirp

every five seconds if the user continues to

deflate the tire.

Selectable Tire Fill Alert (STFA) —

If Equipped

The Selectable Tire Fill Alert (STFA) system is an

optional feature that is included as part of the

normal Tire Fill Alert system. The system is

designed to allow you to select a pressure to inflate

or deflate the vehicle's front and rear axle tires to,

and to provide feedback while inflating or deflating

the vehicle's tires.

SAFETY

269

In the Selectable Tire Fill Alert application, which is

located in the apps menu of the Uconnect system,

you will be able to select a pressure setting for both

the front and rear axle tire pressures by scrolling

through a pressure range from ≥15 psi to XX in

1 psi increments for each axle setting.
XX = the vehicle's cold placard pressure values for

the front and rear axles as shown on the vehicle

placard pressure label.
You may also store pressure values chosen for

each axle in the Uconnect system application as

preset pressure values. Up to two sets of preset

pressure values can be stored in the Uconnect

system for the front and rear axle. Once you select

the tire pressures for the front and rear axles that

you want to inflate or deflate to, you can begin

inflating or deflating one tire at a time.
NOTE:

The STFA system will only support inflating or

deflating one tire at a time. The user is required to

wait until the hazard lights STOP flashing or 26-30

seconds after the desired pressure is achieved in

one wheel before switching to another.
The system will be activated when the TPMS

receiver module detects a change in tire pressure.

The ignition must be in the ON/RUN mode, with the

transmission in PARK in vehicles with an automatic

transmission, and in NEUTRAL with the parking

brake engaged in vehicles with a manual

transmission. The hazard lamps will come on to

confirm the vehicle is in Tire Fill Alert mode.
When Tire Fill Alert mode is entered, the tire

pressure screen will be displayed in the instrument

cluster. If the hazard lamps do not come on while

inflating or deflating the tire, the Tire Pressure

Monitoring System sensor may be in an

inoperative position, preventing the TPMS sensor

signal from being received. In this case, the vehicle

may need to be moved slightly forward or

backward.
Horn chirps will indicate STFA status as tires are

inflated/deflated. The horn will chirp under the

following STFA states:
1. The horn will chirp once when the selected

pressure is reached to let you know when to

stop inflating or deflating the tire.

2. The horn will chirp three times if the tire is

overinflated or over-deflated.

3. The horn will chirp once again when enough air

is added or removed to reach proper selected

pressure level.

OCCUPANT RESTRAINT SYSTEMS

Some of the most important safety features in your

vehicle are the restraint systems:

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.

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 289.

270

SAFETY

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 289.

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 403 for customer service contact

information.

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



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.

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!

272

SAFETY

(Continued)



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.

WARNING!



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.



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.

WARNING!



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.



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.

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.

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

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 Upper 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.

SAFETY

275

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 298.

The figure provided illustrates the locking feature

for each seating position.

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

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.

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.

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.
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.
This vehicle may be equipped with driver and/or

front passenger seat track position sensors that

may adjust the inflation rate of the Advanced Front

Air Bags based upon seat position.
This vehicle is equipped with a right front

that is designed to provide Passenger Advanced

Front Air Bag output appropriate to the occupant’s

seated weight input, as determined by the OCS.

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.

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!



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!

280

SAFETY

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 Restraints 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.

Occupant Classification System (OCS) —

Front Passenger Seat

The Occupant Classification System (OCS) is part of a

Federally regulated safety system for this vehicle. It is

designed to provide Passenger Advanced Front Air

Bag output appropriate to the occupant’s seated

weight, as determined by the OCS.

The Occupant Classification System (OCS) consists

of the following:



Occupant Restraint Controller (ORC)



Occupant Classification Module (OCM) and

Sensor located in the front passenger seat



Air Bag Warning Light

Occupant Classification Module (OCM) And Sensor
The Occupant Classification Module (OCM) is

located underneath the front passenger seat. The

Sensor is located beneath the passenger seat

cushion foam. Any weight on the seat will be

sensed by the Sensor. The OCM uses input from

the Sensor to determine the front passenger’s

most probable classification. The OCM

communicates this information to the ORC. The

ORC may reduce the inflation rate of the Passenger

Advanced Front Air Bag deployment based on

occupant classification. In order for the OCS to

operate as designed, it is important for the front

passenger to be seated properly and properly

wearing the seat belt.
The OCS will NOT prevent deployment of the

Passenger Advanced Front Air Bag. The OCS may

reduce the inflation rate of the Passenger

Advanced Front Air Bag if the OCS estimates that:



The front passenger seat is unoccupied or has

very light objects on it; or



The front passenger seat is occupied by a small

passenger, including a child; or



The front passenger seat is occupied by a

rear-facing child restraint; or



The front passenger is not properly seated or his

or her weight is taken off of the seat for a period

of time.

* It is possible for a child to be classified as an

adult, allowing a full-power Passenger Advanced

Front Air Bag deployment. Never allow children to

ride in the front passenger seat and never install a

child restraint system, including a rear-facing child

restraint, in the front passenger seat.

SAFETY

281

The OCS determines the front passenger’s most

probable classification. The OCS estimates the

seated weight on the front passenger seat and

where that weight is located. The OCS

communicates the classification status to the ORC.

The ORC uses the classification to determine

whether the Passenger Advanced Front Air Bag

inflation rate should be adjusted.

In order for the OCS to operate as designed, it is

important for the front passenger to be seated

properly and properly wearing the seat belt.

Properly seated passengers are:



Sitting upright



Facing forward



Sitting in the center of the seat with their feet

comfortably on or near the floor



Sitting with their back against the seatback and

the seatback in an upright position

Seated Properly

Lighter Weight Passengers (Including Small Adults)
When a lighter weight passenger, including a small

adult, occupies the front passenger seat, the OCS

may reduce the inflation rate of the Passenger

Advanced Front Air Bag. This does not mean that

the OCS is working improperly.
Do not decrease OR increase the front passenger’s

seated weight on the front passenger seat
The front passenger’s seated weight must be

properly positioned on the front passenger seat.

Failure to do so may result in serious injury or

death. The OCS determines the most probable

classification of the occupant that it detects. The

OCS will detect the front passenger’s decreased or

increased seated weight, which may result in an

adjusted inflation rate of the Passenger Advanced

Front Air Bag in a collision. This does not mean that

the OCS is working improperly. Decreasing the

front passenger’s seated weight on the front

passenger seat may result in a reduced-power

deployment of the Passenger Advanced Front Air

Bag. Increasing the front passenger’s seated

weight on the front passenger seat may result in a

full-power deployment of the Passenger Advanced

Front Air Bag.

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.



Children 12 years or younger should always

ride buckled up in the rear seat of a vehicle

with a rear seat.

282

SAFETY

Examples of improper front passenger seating

include:



The front passenger’s weight is transferred to

another part of the vehicle (like the door, arm

rest or instrument panel).



The front passenger leans forward, sideways, or

turns to face the rear of the vehicle.



The front passenger’s seatback is not in the full

upright position.



The front passenger carries or holds an object

while seated (e.g., backpack, box, etc.).



Objects are lodged under the front passenger

seat.



Objects are lodged between the front passenger

seat and center console.



Accessories that may change the seated weight

on the front passenger seat are attached to the

front passenger seat.



Anything that may decrease or increase the

front passenger’s seated weight.

The OCS determines the front passenger’s most

probable classification. If an occupant in the front

passenger seat is seated improperly, the occupant

may provide an output signal to the OCS that is

different from the occupant’s properly seated

weight input, for example:

Not Seated Properly

SAFETY

283

The Air Bag Warning Light in the instrument

panel will turn on whenever the OCS is unable to

classify the front passenger seat status. A

malfunction in the OCS may affect the operation of

the air bag system.
If the Air Bag Warning Light does not come on,

or stays on after you start the vehicle, or it comes

on as you drive, take the vehicle to an authorized

dealer for service immediately.
The passenger seat assembly contains critical OCS

components that may affect the Passenger

Advanced Front Air Bag inflation. In order for the

OCS to properly classify the seated weight of a

front seat passenger, the OCS components must

function as designed. Do not make any

modifications to the front passenger seat

components, assembly, or to the seat cover. If the

seat, trim cover, or cushion needs service for any

reason, take the vehicle to an authorized dealer.

Only FCA US LLC approved seat accessories may

be used.
The following requirements must be strictly

followed:



Do not modify the front passenger seat

assembly or components in any way.



Do not use prior or future model year seat

covers or cushions not designated by FCA US

LLC for the specific model being repaired.

Always use the correct seat cover and cushion

specified for the vehicle.



Do not replace the seat cover or cushion with an

aftermarket seat cover or cushion.



Do not add a secondary seat cover or mat.



At no time should any Supplemental Restraint

System (SRS) component or SRS related

component or fastener be modified or replaced

with any part except those which are approved

by FCA US LLC.

WARNING!



If a child restraint system, child, small teen

ager or adult in the front passenger seat is

seated improperly, the occupant may provide

an output signal to the OCS that is different

from the occupant’s properly seated weight

input. This may result in serious injury or death

in a collision.



Always wear your seat belt and sit properly,

with the seatback in an upright position, your

back against the seatback, sitting upright,

facing forward, in the center of the seat, with

your feet comfortably on or near the floor.



Do not carry or hold any objects (e.g., back

packs, boxes, etc.) while seated in the front

passenger seat. Holding an object may

provide an output signal to the OCS that is

different than the occupant’s properly seated

weight input, which may result in serious injury

or death in a collision.



Placing an object on the floor under the front

passenger seat may prevent the OCS from

working properly, which may result in serious

injury or death in a collision. Do not place any

objects on the floor under the front passenger

seat.

WARNING!



Unapproved modifications or service proce

dures to the passenger seat assembly, its

related components, seat cover or cushion

may inadvertently change the air bag deploy

ment in case of a frontal collision. This could

result in death or serious injury to the front

passenger if the vehicle is involved in a colli

sion. A modified vehicle may not comply with

required Federal Motor Vehicle Safety Stan

dards (FMVSS) and/or Canadian Motor

Vehicle Safety Standards (CMVSS).



If it is necessary to modify the air bag system

for persons with disabilities, contact an autho

rized dealer.
