NOTE:A key that has not been programmed is also
considered an invalid key, even if it is cut to fit the
ignition switch lock cylinder for that vehicle.
During normal operation, after turning on the ignition
switch, the Vehicle Security Light will turn on for three
seconds for a bulb check. If the light remains on after the
bulb check, it indicates that there is a problem with the
electronics. In addition, if the Vehicle Security Light
begins to flash after the bulb check, it indicates that
someone used an invalid key to try to start the engine.
Either of these conditions will result in the engine being
shut off after two seconds.
If the Vehicle Security Light turns on during normal
vehicle operation (vehicle running for longer than 10 sec-
onds), it indicates that there is a fault in the electronics.
Should this occur, have the vehicle serviced as soon as
possible by an authorized dealer. NOTE:
•The Sentry Key
Immobilizer System is not compat-
ible with some aftermarket remote starting systems.
Use of these systems may result in vehicle starting
problems and loss of security protection.
•Exxon/Mobil Speedpass™, additional Sentry Keys ,
or any other transponder-equipped components on
the same key chain will notcause a key-related
(transponder) fault unless the additional part is physi-
cally held against the ignition key being used when
starting the vehicle. Cell phones, pagers, or other
Radio Frequency (RF) electronics will not cause inter-
ference with this system.
All of the keys provided with your new vehicle have
been programmed to the vehicle electronics.

NOTE:Changes or modifications not expressly ap-
proved by the party responsible for compliance could
void the user’s authority to operate the equipment.
If your RKE transmitter fails to operate from a normal
distance, check for these two conditions:
1. Weak battery in RKE transmitter. The expected life of
the battery is from one to two years.
2. Closeness to a radio transmitter such as a radio station
tower, airport transmitter, and some mobile or CB radios.
REMOTE STARTING SYSTEM — IF EQUIPPED
This system uses the Remote Keyless Entry
(RKE) transmitter to start the engine conve-
niently from outside the vehicle while still
maintaining security. The system has a range of
328 ft (100 m).
NOTE: The vehicle must be equipped with an auto-
matic transmission to be equipped with Remote Start.
How To Use Remote Start
All of the following conditions must be met before the
engine will remote start:
•Shift lever in PARK.
•Doors closed.
•Hood closed.
•Liftgate closed.
•Hazard switch off.
•Brake switch inactive (brake pedal not pressed).
•Ignition key removed from ignition switch.
•Battery at an acceptable charge level.
•RKE PANIC button not pressed.

If it is necessary to sit in a parked vehicle with the engine
running, adjust your heating or cooling controls to force
outside air into the vehicle. Set the blower at high speed.
If you are required to drive with the trunk/liftgate open,
make sure that all windows are closed and the climate
control BLOWER switch is set at high speed. DO NOT
use the recirculation mode.
The best protection against carbon monoxide entry into
the vehicle body is a properly maintained engine exhaust
system.
Whenever a change is noticed in the sound of the exhaust
system, when exhaust fumes can be detected inside the
vehicle, or when the underside or rear of the vehicle is
damaged, have a competent mechanic inspect the com-
plete exhaust system and adjacent body areas for broken,
damaged, deteriorated, or mispositioned parts. Openseams or loose connections could permit exhaust fumes
to seep into the passenger compartment. In addition,
inspect the exhaust system each time the vehicle is raised
for lubrication or oil change. Replace as required.
Safety Checks You Should Make Inside the
Vehicle
Seat Belts
Inspect the belt system periodically, checking for cuts,
frays, and loose parts. Damaged parts must be replaced
immediately. Do not disassemble or modify the system.
Front seat belt assemblies must be replaced after a
collision. Rear seat belt assemblies must be replaced after
a collision if they have been damaged (i.e., bent retractor,
torn webbing, etc.). If there is any question regarding belt
or retractor condition, replace the belt.
82 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Airbag Warning Light
The light should come on and remain on for six to eight
seconds as a bulb check when the ignition switch is first
turned ON. If the light is not lit during starting, see your
authorized dealer. If the light stays on, flickers, or comes
on while driving, have the system checked by an autho-
rized dealer.
Defroster
Check operation by selecting the defrost mode and place
the blower control on high speed. You should be able to
feel the air directed against the windshield. See your
authorized dealer for service if your defroster is
inoperable.
Periodic Safety Checks You Should Make Outside
the Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objectslodged in the tread. Inspect the tread and sidewall for
cuts and cracks. Check the wheel nuts for tightness.
Check the tires (including spare) for proper pressure.
Lights
Have someone observe the operation of exterior lights
while you work the controls. Check turn signal and high
beam indicator lights on the instrument panel.
Door Latches
Check for positive closing, latching, and locking.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
engine coolant, oil, or other fluid leaks. Also, if gasoline
fumes are detected or if fuel, power steering fluid, or
brake fluid leaks are suspected, the cause should be
located and corrected immediately.

defroster automatically turns off after approximately
10 minutes. For an additional five minutes of operation,
press the button a second time.
NOTE:To prevent excessive battery drain, use the rear
window defroster only when the engine is operating.
CAUTION!
Failure to follow these cautions can cause damage to
the heating elements:
•Use care when washing the inside of the rear
window. Do not use abrasive window cleaners on
the interior surface of the window. Use a soft cloth
and a mild washing solution, wiping parallel to
the heating elements. Labels can be peeled off
after soaking with warm water.
(Continued)
CAUTION! (Continued)
•Do not use scrapers, sharp instruments, or abra-
sive window cleaners on the interior surface of the
window.
•Keep all objects a safe distance from the window.
ROOF LUGGAGE RACK — IF EQUIPPED
NOTE:Roof rack and crossbars cannot be used on
vehicles equipped with Skyslider.
The load carried on the roof, when equipped with a
luggage rack, must not exceed 150 lbs (68 kg), and it
should be uniformly distributed over the cargo area.
Crossbars should always be used whenever cargo is
placed on the roof rack. Check the straps frequently to be
sure that the load remains securely attached.
NOTE: Crossbars are offered by MOPAR accessories.

5. Electronic Throttle Control (ETC) LightThis light informs you of a problem with the
Electronic Throttle Control (ETC) system. If a
problem is detected, the light will come on
while the engine is running. Cycle the ignition
key when the vehicle has completely stopped and the
shift lever is placed in the PARK position. The light
should turn off. If the light remains lit with the engine
running, your vehicle will usually be drivable; however,
see an authorized dealer for service as soon as possible. If
the light is flashing when the engine is running, imme-
diate service is required and you may experience reduced
performance, an elevated/rough idle or engine stall and
your vehicle may require towing. The light will come on
when the ignition is first turned ON and remain on
briefly as a bulb check. If the light does not come on
during starting, have the system checked by an autho-
rized dealer. 6. Malfunction Indicator Light (MIL)
The Malfunction Indicator Light (MIL) is part of
an onboard diagnostic system, called OBD, that
monitors engine and automatic transmission con-
trol systems. The light will illuminate when the key is in
the ON position, before engine start. If the bulb does not
come on when turning the key from OFF to ON, have the
condition checked promptly.
Certain conditions such as a loose or missing gas cap,
poor fuel quality, etc., may illuminate the MIL after
engine start. The vehicle should be serviced if the light
stays on through several of your typical driving cycles. In
most situations, the vehicle will drive normally and will
not require towing.
If the MIL flashes when the engine is running, serious
conditions may exist that could lead to immediate loss of
power or severe catalytic converter damage. The vehicle
should be serviced as soon as possible if this occurs.

7. High Beam IndicatorThis indicator shows that the high beam head-
lights are on. Pull the multifunction control lever
on the left side of the steering column toward you to
switch to low beam.
8. Front Fog Light Indicator — If Equipped This indicator will illuminate when the fog lights
are on.
9. Speedometer
Shows the vehicle speed.
10. Turn Signal Indicators The arrow will flash with the exterior turn signal
when the turn signal lever is operated.
If the vehicle electronics sense that the vehicle has
traveled about 1 mile (1.6 km) with the turn signals on, a continuous chime will sound to alert you to turn the
signals off. If either indicator flashes at a rapid rate, check
for a defective outside light bulb.
11. Electronic Stability Program (ESP) Indicator Light
/ Traction Control System (TCS) Indicator Light
If this indicator light flashes during accelera-
tion, apply as little throttle as possible. While
driving, ease up on the accelerator. Adapt your
speed and driving to the prevailing road con-
ditions, and do not switch off the Electronic Stability
Program (ESP), or Traction Control System (TCS).
12. Charging System Light This light shows the status of the electrical charg-
ing system. The light should come on when the
ignition switch is first turned ON and remain on briefly
as a bulb check. If the light stays on or comes on while
driving, turn off some of the vehicle’s non-essential
electrical devices or increase engine speed (if at idle). If

the charging system light remains on, it means that the
vehicle is experiencing a problem with the charging
system. Obtain SERVICE IMMEDIATELY. See an autho-
rized dealer.
13. Oil Pressure Warning LightThis light indicates low engine oil pressure. The
light should turn on momentarily when the engine
is started. If the light turns on while driving, stop the
vehicle and shut off the engine as soon as possible. A
chime will sound for four minutes when this light turns
on.
Do not operate the vehicle until the cause is corrected.
This light does not indicate how much oil is in the engine.
The engine oil level must be checked under the hood. 14. Anti-Lock Brake (ABS) Light
This light monitors the Anti-Lock Brake System
(ABS). The light will turn on when the ignition
switch is turned to the ON position and may
stay on for as long as four seconds.
If the ABS light remains on or turns on while driving, it
indicates that the Anti-Lock portion of the brake system
is not functioning and that service is required. However,
the conventional brake system will continue to operate
normally if the BRAKE warning light is not on.
If the ABS light is on, the brake system should be serviced
as soon as possible to restore the benefits of Anti-Lock
brakes. If the ABS light does not turn on when the
Ignition switch is turned to the ON position, have the
light inspected by an authorized dealer.
