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
•The Sentry KeyImmobilizer 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: Only keys that are programmed to the vehicle
electronics can be used to start and operate the vehicle.
Once a Sentry Key is programmed to a vehicle, it cannot
be programmed to any other vehicle.

VEHICLE SECURITY ALARM SYSTEM — IF
This Vehicle Security Alarm system monitors the vehicle
doors and ignition for unauthorized operation. When the
alarm is activated, the system provides both audible and
visible signals. For the first three minutes the horn will
sound and the headlights and security light will flash
repeatedly. For an additional 15 minutes only, the head-
lights and security light will flash. The engine will run
only if a valid Sentry Keyis used to start the vehicle.
Use of the Sentry Key will disable the alarm.
Rearming of the System
The Vehicle Security Alarm system will rearm itself after
the 15 additional minutes of headlights and security light
flashing, if the system has not been disabled. If the
condition which initiated the alarm is still present, the
system will ignore that condition and monitor the re-
maining doors and ignition.
To Set the Alarm
The Vehicle Security Alarm will set when you use the
power door locks, or use the Remote Keyless Entry (RKE)
transmitter to lock the doors. After all the doors are
locked and closed, the Vehicle Security Light in the
instrument cluster will flash rapidly to signal that the
system 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 system is armed.
NOTE:If the Vehicle Security Light stays on continu-
ously during vehicle operation, have the system checked
by an authorized dealer.

To Disarm the System
Use the RKE transmitter to unlock the door. If something
has triggered the system in your absence, the horn will
sound three times when you unlock the doors and the
Vehicle Security Light will flash for 30 seconds. Check the
vehicle for tampering.
The Vehicle Security Alarm system will also disarm if the
vehicle is started with a programmed Sentry Key.Ifan
unprogrammed 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 system is designed to protect
your vehicle; however, you can create conditions where
the system 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
system will not arm.
ILLUMINATED ENTRY SYSTEM — IF EQUIPPED
The courtesy lights will turn on when you use the
Remote Keyless Entry (RKE) transmitter or open the
doors. This feature is only available if you have Remote
The lights will fade to off after about 30 seconds, or they
will immediately fade to off once the ignition switch is
•The front courtesy overhead console and door cour-
tesy lights do not turn off if the dimmer control is in
the interior lights on position (extreme top position).
•The Illuminated Entry system will not operate if the
dimmer control is in the extreme downward position.

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
•The light flickers or comes on and remains on while
If the speedometer, tachometer or any engine
related gauges are not working, the ORC may also be
disabled. The airbags may not be ready to inflate for your
protection. Promptly check the fuse block for blown
fuses. For proper location of airbag fuses, refer to “Fuses
(Integrated Power Module)” in Section 7. See your au-
thorized dealer if the fuse is good.
Event Data Recorder (EDR)
In the event of an accident, your vehicle is designed to
record up to approximately five seconds of specific
vehicle data parameters (see the following list) in an
event data recorder prior to the moment of airbag de-
ployment, or near deployment, and up to a quarter-
second of high-speed deceleration data during and/or
after airbag deployment. EDR data are ONLY recorded if
an airbag deploys, or nearly deploys, and are otherwise

Children Too Large for Booster Seats
Children who are large enough to wear the shoulder belt
comfortably, and whose legs are long enough to bend
over the front of the seat when their back is against the
seat back should use the lap/shoulder belt in a rear seat.
•Make sure that the child is upright in the seat.
•The lap portion should be low on the hips and as snug
•Check belt fit periodically. A child’s squirming or
slouching can move the belt out of position.
If the shoulder belt contacts the face or neck, move the
child closer to the center of the vehicle. Never allow a
child to put the shoulder belt under an arm or behind
Airbags deploying in the front seat could harm your pet.
An unrestrained pet will be thrown about and possibly injured, or injure a passenger during panic braking or in
a collision. Pets should be restrained in the rear seat in
pet harnesses or pet carriers that are secured by seat belts.
NEW ENGINE BREAK-IN
5.7L Gas Engine – 3500 Models Only
A long break-in period is not required for the engine in
your new vehicle. Drive moderately during the first 300
mi (500 km). After the initial 60 mi (100 km), speeds up to
50 or 55 mph (80 or 90 km/h) are desirable. While
cruising, brief full-throttle acceleration within the limits
of local traffic laws contributes to a good break-in.
Avoid wide open throttle acceleration in low gear.
The engine oil installed in the engine at the factory is a
high quality, energy conserving type lubricant. Oil
changes should be consistent with the anticipated cli-
matic conditions under which vehicle operation will

Be aware of changes in the sound of the exhaust system,
exhaust fumes detected inside the vehicle, or damage to
the underside or rear of the vehicle. Have a competent
mechanic inspect the complete exhaust system and adja-
cent 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 or adjust as required.Safety Checks You Should Make Inside The
Heater Defroster Ducts
Inspect the heater defroster ducts for proper operation.
Check for proper airflow through all defroster ducts. If
there is any question regarding the operation of your
heater defroster ducts, have the system checked by an

cuts, frays and loose parts. Damaged parts must be
replaced immediately. Do not disassemble or modify the
Seat belt assemblies must be replaced after an accident if
they have been damaged (bent retractor, torn webbing,
etc.) or if the front airbags have deployed. If there is any
question regarding seat belt or retractor condition, re-
place the seat belt.

INSTRUMENT CLUSTER DESCRIPTION
1. Check GaugesThis 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.
•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 Lights in instrument cluster flash when outside turn
signals are operating.

5. Airbag Warning Light The indicator lights and remains lit for six to
eight seconds when the ignition is first turned
on. If the light stays on, flickers or comes on
while driving, have the airbag system checked
by an authorized dealer.
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 seat belt remains
unbuckled, the Seat Belt Warning Light will flash or
remain on continuously. Refer to Enhanced Driver Seat
Belt Reminder System (BeltAlert) under “Occupant
Restraints” in section 2.
The speedometer shows the vehicle speed in miles per
hour and/or kilometers per hour.

9. Oil Pressure GaugeThe 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.
NOTE: If the gauge pointer moves to either extreme of
the gauge, the “Check Gauges” indicator will illuminate
and a single chime will sound.
