monitors engine and automatic

transmission control systems. This warning light

will illuminate when the ignition is in the ON/RUN

position before engine start. If the bulb does not

come on when turning the ignition switch from OFF

to ON/RUN, have the condition checked promptly.
Certain conditions, such as a loose or missing gas

cap, poor quality fuel, etc., may illuminate the light

after engine start. The vehicle should be serviced if

the light stays on through several typical driving

styles. In most situations, the vehicle will drive

normally and will not require towing.
When the engine is running, the MIL may flash to

alert serious conditions that could lead to

immediate loss of power or severe catalytic

converter damage. The vehicle should be serviced

by an authorized dealer as soon as possible if this

occurs.

Service 4WD Warning Light — If Equipped

This warning light will illuminate to signal

a fault with the 4WD system. If the light

stays on or comes on during driving, it

means that the 4WD system is not

functioning properly and that service is required. It

is recommend you drive to the nearest service

center and have the vehicle serviced immediately.

WARNING!

A malfunctioning catalytic converter, as

referenced above, can reach higher

temperatures than in normal operating

conditions. This can cause a fire if you drive

slowly or park over flammable substances such

as dry plants, wood, cardboard, etc. This could

result in death or serious injury to the driver,

occupants or others.

CAUTION!

Prolonged driving with the Malfunction Indicator

Light (MIL) on could cause damage to the

Tire Pressure Monitoring System (TPMS)

Warning Light

The warning light switches on and a

message is displayed to indicate that the

tire pressure is lower than the

recommended value and/or that slow

pressure loss is occurring. In these cases, optimal

tire life and fuel consumption may not be

guaranteed.
Should one or more tires be in the condition

mentioned above, the display will show the

indications corresponding to each tire.

Each tire, including the spare (if provided), should

be checked monthly when cold and inflated to the

inflation pressure recommended by the vehicle

manufacturer on the vehicle placard or tire

inflation pressure label. If your vehicle has tires of

a different size than the size indicated on the

vehicle placard or tire inflation pressure label, you

should determine the proper tire inflation pressure

for those tires.
As an added safety feature, your vehicle has been

equipped with a TPMS that illuminates a low tire

pressure telltale when one or more of your tires is

significantly underinflated. Accordingly, when the

low tire pressure telltale illuminates, you should

stop and check your tires as soon as possible and

inflate them to the proper pressure. Driving on a

significantly underinflated tire causes the tire to

overheat and can lead to tire failure. Underinflation

also reduces fuel efficiency and tire tread life, and

may affect the vehicle’s handling and stopping

ability.

WARNING!

Do not continue driving with one or more flat

tires as handling may be compromised. Stop the

vehicle, avoiding sharp braking and steering. If a

tire puncture occurs, repair immediately using

the dedicated tire repair kit and contact an

authorized dealer as soon as possible.

144

GETTING TO KNOW YOUR INSTRUMENT PANEL

Please note that the TPMS is not a substitute for

proper tire maintenance, and it is the driver’s

responsibility to maintain correct tire pressure,

even if underinflation has not reached the level to

trigger illumination of the TPMS low tire pressure

telltale.
Your vehicle has also been equipped with a TPMS

malfunction indicator to indicate when the system

is not operating properly. The TPMS malfunction

indicator is combined with the low tire pressure

telltale. When the system detects a malfunction,

the telltale will flash for approximately one minute

and then remain continuously illuminated. This

sequence will continue upon subsequent vehicle

start-ups as long as the malfunction exists. When

the malfunction indicator is illuminated, the

system may not be able to detect or signal low tire

pressure as intended. TPMS malfunctions may

occur for a variety of reasons, including the

installation of replacement or alternate tires or

wheels on the vehicle that prevent the TPMS from

functioning properly. Always check the TPMS

malfunction telltale after replacing one or more

tires or wheels on your vehicle to ensure that the

replacement or alternate tires and wheels allow

the TPMS to continue to function properly.

ONBOARD DIAGNOSTIC SYSTEM — OBD II

Your vehicle is equipped with a sophisticated

Onboard Diagnostic system called OBD II. This

system monitors the performance of the

emissions, engine, and transmission control

systems. When these systems are operating

properly, your vehicle will provide excellent

performance and fuel economy, as well as engine

emissions well within current government

regulations.

If any of these systems require service, the OBD II

system will turn on the Malfunction Indicator Light

(MIL). It will also store diagnostic codes and other

information to assist your service technician in

making repairs. Although your vehicle will usually

be drivable and not need towing, see an authorized

dealer for service as soon as possible.

related to the performance of your emissions

controls. Authorized service technicians may need

to access this information to assist with the

diagnosis and service of your vehicle and

emissions system

page 227.

CAUTION!



Prolonged driving with the MIL on could cause

further damage to the emission control

system. It could also affect fuel economy and

driveability. The vehicle must be serviced

before any emissions tests can be performed.

EMISSIONS INSPECTION AND

MAINTENANCE PROGRAMS

In some localities, it may be a legal requirement to

pass an inspection of your vehicle's emissions

control system. Failure to pass could prevent

vehicle registration.

For states and/or provinces that require

an Inspection and Maintenance (I/M),

this check verifies the Malfunction

Indicator Light (MIL) is functioning and is

not on when the engine is running, and that the

OBD II system is ready for testing.
The OBD II system may not be ready if your vehicle

was recently serviced, recently had a depleted

battery or a battery replacement. If the OBD II

system should be determined not ready for the I/M

test, your vehicle may fail the test.
Your vehicle has a simple ignition actuated test,

which you can use prior to going to the test station.

To check if your vehicle's OBD II system is ready,

you must do the following:
1. Cycle the ignition switch to the ON position,

but do not crank or start the engine.

NOTE:

If you crank or start the engine, you will have to

start this test over.
2. As soon as you cycle the ignition switch to the

ON position, you will see the Malfunction

Indicator Light (MIL) symbol come on as part of

a normal bulb check.

3. Approximately 15 seconds later, one of two

things will happen:



The MIL will flash for about 10 seconds and

then return to being fully illuminated until

you turn OFF the ignition or start the engine.

This means that your vehicle's OBD II

system is not ready and you should not

proceed to the I/M station.



The MIL will not flash at all and will remain

fully illuminated until you place the ignition

in the off position or start the engine. This

means that your vehicle's OBD II system is

ready and you can proceed to the I/M

station.

If your OBD II system is not ready, you should see

an authorized dealer or repair facility. If your

vehicle was recently serviced or had a battery

failure or replacement, you may need to do nothing

more than drive your vehicle as you normally would

in order for your OBD II system to update. A

recheck with the above test routine may then

indicate that the system is now ready.
Regardless of whether your vehicle's OBD II system

is ready, if the MIL is illuminated during normal

vehicle operation you should have your vehicle

serviced before going to the I/M station. The I/M

station can fail your vehicle because the MIL is on

with the engine running.

WARNING!



ONLY an authorized service technician should

connect equipment to the OBD II connection

port in order to read the VIN, diagnose, or

service your vehicle.



If unauthorized equipment is connected to the

OBD II connection port, such as a

driver-behavior tracking device, it may:



Be possible that vehicle systems,

including safety related systems, could be

impaired or a loss of vehicle control could

occur that may result in an accident

involving serious injury or death.



Access, or allow others to access, infor

mation stored in your vehicle systems,

including personal information.



Driver inattention could lead to failure to place

the vehicle in PARK. ALWAYS DO A VISUAL

CHECK that your vehicle is in PARK by verifying

that a solid (not blinking) “P” is indicated in

the instrument cluster display and on the gear

selector. If the "P" indicator is blinking, your

vehicle is not in PARK. As an added precau

tion, always apply the parking brake when

exiting the vehicle.

TART

If the engine fails to start after you have followed

the “Normal Starting” procedure, and had not

experienced an extended park condition (i.e.,

parked for more than 30 days), it may be flooded.

Push the accelerator pedal all the way to the floor

and hold it there while the engine is cranking. This

should clear any excess fuel in case the engine is

flooded. The starter motor will engage

automatically, run for 10 seconds, and then

disengage. Once this occurs, release the

accelerator pedal and the brake pedal, wait 10 to

15 seconds, then repeat the “Normal Starting”

procedure.

FTER

TARTING

The idle speed is controlled automatically and will

decrease as the engine warms up.

STARTING THE ENGINE — DIESEL ENGINE

(IF EQUIPPED)

Before starting your vehicle, adjust your seat, both

inside and outside mirrors, and fasten your seat

belts.
The starter is allowed to crank for up to 25-second

intervals. Waiting two minutes between such

intervals will protect the starter from overheating.

WARNING!



Never pour fuel or other flammable liquid into

the throttle body air inlet opening in an

attempt to start the vehicle. This could result

in flash fire causing serious personal injury.



Do not attempt to push or tow your vehicle to

get it started. Vehicles equipped with an auto

matic transmission cannot be started this

way. Unburned fuel could enter the catalytic

converter and once the engine has started,

ignite and damage the converter and vehicle.



If the vehicle has a discharged battery,

booster cables may be used to obtain a start

from a booster battery or the battery in

another vehicle. This type of start can be

dangerous if done improperly

page 373.

CAUTION!

To prevent damage to the starter, do not

continuously crank the engine for more than 10

seconds at a time. Wait 10 to 15 seconds before

trying again.

WARNING!



Before exiting a vehicle, always come to a

complete stop, then shift the automatic trans

mission into PARK and apply the parking

brake.



Always make sure the keyless ignition node is

in the OFF position, key fob is removed from

the vehicle and vehicle is locked.



Never leave children alone in a vehicle, or with

access to an unlocked vehicle. Leaving chil

dren in a vehicle unattended is dangerous for

a number of reasons. A child or others could

be seriously or fatally injured. Children should

be warned not to touch the parking brake,

brake pedal or the gear selector.



Do not leave the key fob in or near the vehicle,

or in a location accessible to children, and do

not leave the ignition of a vehicle equipped

with Keyless Enter ‘n Go™ in the ACC or ON/

RUN position. A child could operate power

windows, other controls, or move the vehicle.



Do not leave children or animals inside parked

vehicles in hot weather. Interior heat build-up

may cause serious injury or death.

The cartridge block heater clips into the engine

block near the water jacket and transfers heat to

the coolant. It requires a 110–115 Volt AC

electrical outlet with a grounded, three-wire

extension cord. Its use is recommended for

environments that routinely fall below -10°F

(-23°C). It should be used when the vehicle has not

been running overnight or longer periods and

should be plugged in two hours prior to start. Its

use is required for cold starts with temperatures

under -20°F (-28°C).

NOTE:

The engine block heater and heater cord are

factory installed options. If your vehicle is not

equipped, engine block heaters and heater cords

are available from an authorized Mopar® dealer.



A 12 Volt heater built into the fuel filter housing

aids in preventing fuel gelling. It is controlled by

a built-in thermostat.



A Diesel Pre-Heat system both improves engine

starting and reduces the amount of white

smoke generated by a warming engine.
