SENTRY KEYThe Sentry KeyImmobilizer System prevents unautho-
rized vehicle operation by disabling the engine. The
system does not need to be armed or activated. Operation
is automatic, regardless of whether the vehicle is locked
or unlocked.
The system uses ignition keys that have an embedded
electronic chip (transponder) to prevent unauthorized
vehicle operation. Therefore, only keys that are pro-
grammed to the vehicle can be used to start and operate
the vehicle. The system will shut the engine off in two
seconds if someone uses an invalid key to try to start the
engine.
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.
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.THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 15

Vehicle Security Alarm is arming. The Vehicle Security
Light in the instrument panel cluster will flash rapidly for
about 16 seconds to indicate that the alarm is being set.
After the alarm is set, the Vehicle Security Light will flash
at a slower rate to indicate that the Vehicle Security
Alarm is armed.
NOTE:If the Vehicle Security Light stays on continu-
ously during vehicle operation, have the Vehicle Security
Alarm checked by an authorized dealer.To Disarm the SystemUse the RKE transmitter to unlock the door. If something
has triggered the Vehicle Security Alarm in your absence,
the horn will sound three times when you unlock the
doors and the Vehicle Security Light will flash for 30 sec-
onds. Check the vehicle for tampering. The Vehicle Security Alarm will also disarm if the vehicle
is started with a programmed Sentry Key. If an unpro-
grammed Sentry Key
is used to start a vehicle, the
engine will run for two seconds and then the Security
Alarm will be initiated. To exit the alarming mode, press
the RKE transmitter UNLOCK button, or start the vehicle
with a programmed Sentry Key.
The Vehicle Security Alarm is designed to protect your
vehicle; however, you can create conditions where the
Vehicle Security Alarm will arm unexpectedly. If you
remain in the vehicle and lock the doors with the RKE
transmitter, the alarm will sound when you pull the door
handle to exit. The door will be locked, but the Vehicle
Security Alarm will not arm.

Enhanced Accident Response SystemIf the airbags deploy after an impact and the electrical
system remains functional, vehicles equipped with
power door locks will unlock automatically. In addition,
approximately five seconds after the vehicle has stopped
moving, the interior lights will light until the ignition
switch is turned off.Airbag Warning Light
You will want to have the airbags ready to
inflate for your protection in an impact. While
the airbag system is designed to be mainte-
nance free, if any of the following occurs, have
an authorized dealer service the system promptly:
•
The Airbag Warning Light does not come on or flickers
during the six to eight seconds when the ignition
switch is first turned ON.
•
The light remains on or flickers after the six to eight-
second interval.
•
The light flickers or comes on and remains on while
driving.
NOTE: If the speedometer, tachometer or any engine-
related gauges are not working, the airbag control mod-
ule may also be disabled. The airbags may not be ready
to inflate for your protection. Promptly check fuse block
for blown fuses. Refer to the label located on the inside of
the fuse block cover for the proper airbag fuses. See your
authorized dealer if the fuse is good.
Event Data Recorder (EDR)In the event of an accident, your vehicle is designed to
record up to five seconds of specific vehicle data param-
eters (see the following list) in an event data recorder
prior to the moment of airbag deployment, or near
deployment, and up to a quarter second of high-speed
deceleration data during and/or after airbag deploy-

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. Open
seams 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 BeltsInspect 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.Airbag Warning LightThe 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.THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 75

DefrosterCheck 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
TiresExamine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged 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.
LightsHave 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 LatchesCheck for positive closing, latching, and locking.Fluid LeaksCheck 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.

INSTRUMENT CLUSTER DESCRIPTION1. Check Gauges – Premium Cluster OnlyThis light illuminates when the Voltmeter, Engine
Oil Pressure or Engine Coolant Temperature
gauges indicate a reading either too high or too low.
Examine the gauges carefully, and follow the instructions
contained below for each indicated problem.
NOTE: When the ignition switch is turned to OFF, the
Fuel Gauge, Voltmeter, Oil Pressure and Engine Coolant
Temperature gauges may not show accurate readings.
When the engine is not running, turn the ignition switch
to ON to obtain accurate readings.
2. Voltmeter When the engine is running, the gauge indicates
the electrical system voltage. The pointer should
stay within the normal range if the battery is charged. If
the pointer moves to either extreme left or right and
remains there during normal driving, the electrical sys-
tem should be serviced. NOTE:
•
If the gauge pointer moves to either extreme of the
gauge, the “Check Gauges” indicator will illuminate
and a single chime will sound.
•
The voltmeter may show a gauge fluctuation at vari-
ous engine temperatures. This cycling operation is
caused by the post-heat cycle of the intake manifold
heater system. The number of cycles and the length of
the cycling operation is controlled by the engine
control module. Post-heat operation can run for sev-
eral minutes, and then the electrical system and volt-
meter needle will stabilize.
3. 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
188 UNDERSTANDING YOUR INSTRUMENT PANEL
Page 191 of 532
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.
4. Tachometer
The Tachometer indicates engine speed in revolutions per
minute.
CAUTION!
Do not operate the engine with the tachometer
pointer at high RPM for extended periods. Engine
damage may occur.
5. Airbag Warning Light This light turns on and remains on for seven
seconds as a bulb check when the ignition
switch is first turned ON. If the light is not on during starting, stays on, or turns on while driving, have
the system inspected by an authorized dealer as soon as
possible.
6. High Beam Indicator
This indicator shows that headlights are on high
beam.
7. Seat Belt Reminder Light When the ignition switch is first turned ON, this
light will turn on for five to eight seconds as a bulb
check. During the bulb check, if the driver’s seat
belt is unbuckled, a chime will sound. After the bulb
check or when driving, if the driver’s seat belt remains
unbuckled, the Seat Belt Reminder Light will illuminate
and the chime will sound. Refer to “Occupant Restraints”
in Section 2 for more information.
8. Speedometer
The Speedometer shows the vehicle speed in miles per
hour and/or kilometers per hour (mph/kph).

9. Oil Pressure Gauge — Premium Cluster OnlyThe pointer should always indicate some oil pres-
sure when the engine is running. A continuous
high or low reading, under normal driving conditions,
may indicate a lubrication system malfunction. Immedi-
ate service should be obtained from an authorized dealer.
NOTE: If the gauge pointer moves to either extreme of
the gauge, the “Check Gauges” indicator will illuminate
and a single chime will sound.
10. Transfer Case Position
This display indicator shows the transfer case position
selection.
For additional information refer to “4-Wheel Drive Op-
eration” in section 5 of this manual. 11. TOW HAUL
The TOW HAUL button is located at the end of
the gear shift lever. This light will illuminate
when the TOW HAUL OD/OFF button is
pushed once.
12. OD/OFF
The OD/OFF button is located at the end of the gear shift
lever. This light will illuminate when the TOW HAUL
OD/OFF button is pushed twice.
13. Temperature Gauge The temperature gauge shows engine coolant tem-
perature. Any reading within the normal range
indicates that the engine cooling system is operat-
ing satisfactorily.
The gauge pointer will likely indicate a higher tempera-
ture when driving in hot weather, up mountain grades,
or when towing a trailer. It should not be allowed to
exceed the upper limits of the normal operating range.190 UNDERSTANDING YOUR INSTRUMENT PANEL

18. Malfunction Indicator Light (MIL)The Malfunction Indicator Light (MIL) is part of
an onboard diagnostic system, called OBD II, 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. 19. Brake Warning Light
This light monitors various brake functions,
including brake fluid level and parking brake
application. If the brake light turns on, it may
indicate that the parking brake is applied, that
the brake fluid level is low, or that there is a problem with
the anti-lock brake system reservoir.
If the light remains on when the parking brake has been
disengaged, and the fluid level is at the full mark on the
master cylinder reservoir, it indicates a possible brake
hydraulic system malfunction or that a problem with the
Brake Booster has been detected by the Anti-Lock Brake
System (ABS) / Electronic Stability Program (ESP) sys-
tem. In this case, the light will remain on until the
condition has been corrected. If the problem is related to
the brake booster, the ABS pump will run when applying
the brake and a brake pedal pulsation may be felt during
each stop.194 UNDERSTANDING YOUR INSTRUMENT PANEL
Page 198 of 532
The light also will turn on when the parking brake is
applied with the ignition switch in the ON position.
NOTE:This light shows only that the parking brake is
applied. It does not show the degree of brake application.
20. 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. 21. Electronic Throttle Control (ETC) Light
This 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.196 UNDERSTANDING YOUR INSTRUMENT PANEL
