SENTRY KEYT
The Sentry KeytImmobilizer 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 Alarm Indicator Light willturn 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 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 Alarm Indicator Light turns on
during normal vehicle operation (vehicle running for
longer than 10 seconds), it indicates that there is a fault in
the electronics. Should this occur, have the vehicle ser-
viced as soon as possible.
NOTE:
²The Sentry KeytImmobilizer 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.

²Exxon/Mobil SpeedpassŸ, additional Sentry Keyst,
or any other transponder-equipped components on
the same key chain willnotcause a key-related
(transponder) fault unless the additional part isphysi-
cally held against the ignition keybeing used when
starting the vehicle. Cell phones, pagers, or other RF
electronics will not cause interference with this system.
All of the keys provided with your new vehicle have
been programmed to the vehicle electronics.
Replacement Keys
NOTE:Only keys that are programmed to the vehicle
electronics can be used to start and operate the vehicle.
Once a Sentry Keytis programmed to a vehicle, it cannot
be programmed to any other vehicle.
CAUTION!
Always remove the Sentry Keystfrom the vehicle
and lock all doors when leaving the vehicle
unattended.
At the time of purchase, the original owner is provided
with a four-digit Personal Identification Number (PIN).
Keep the PIN in a secure location. This number is
required for authorized dealer replacement of keys. Du-
plication of keys may be performed at an authorized
dealer or by following the customer key programming
procedure. This procedure consists of programming a
blank key to the vehicle electronics. A blank key is one
that has never been programmed.
NOTE:When having the Sentry KeytImmobilizer
System serviced, bring all vehicle keys with you to an
authorized dealer.
16 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Customer Key Programming
If you have two valid Sentry Keyst, you can program
new Sentry Keystto the system by performing the
following procedure:
1. Cut the additional Sentry KeytTransponder blank(s)
to match the ignition switch lock cylinder key code.
2. Insert the first valid key into the ignition switch. Turn
the ignition switch to the ON position for at least three
seconds, but no longer than 15 seconds. Then, turn the
ignition switch to the LOCK position and remove the first
key.
3. Insert the second valid key into the ignition switch.
Turn the ignition switch to the ON position within 15
seconds. After 10 seconds, a chime will sound. In addi-
tion, the Vehicle Security Alarm Indicator Light will
begin to flash. Turn the ignition switch to the LOCK
position and remove the second key.4. Insert a blank Sentry Keytinto the ignition switch.
Turn the ignition switch to the ON position within 60
seconds. After 10 seconds, a single chime will sound. In
addition, the Vehicle Security Alarm Indicator Light will
stop flashing. To indicate that programming is complete,
the Vehicle Security Alarm Indicator Light will turn on
again for three seconds and then turn off.
The new Sentry Keytis programmed.The Remote
Keyless Entry (RKE) transmitter will also be pro-
grammed during this procedure.
Repeat this procedure to program up to eight keys. If you
do not have a programmed Sentry Keyt, contact your
authorized dealer for details.

NOTE:If you turned the wheel to the right to engage
the lock, you must turn the wheel slightly to the right to
disengage it. If you turned the wheel to the left to engage
the lock, turn the wheel slightly to the left to disengage it.
Automatic Transmission Ignition Interlock System
This system prevents the key from being removed unless
the shift lever is in PARK. It also prevents shifting out of
PARK unless the key is in the ON position, and the brake
pedal is depressed.
SECURITY ALARM SYSTEM Ð IF EQUIPPED
This 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 telltale will flash repeatedly. For an addi-
tional 15 minutes only, the headlights and security telltalewill flash. The engine will run only if a valid Sentry Keyt
is used to start the vehicle. Use of the Sentry Keytwill
disable the alarm.
Rearming of the System:
The Security Alarm System will rearm itself after the 15
additional minutes of headlights and security telltale
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 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 SECURITY light in the instrument cluster will
flash rapidly to signal that the system is arming. The
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 SECURITY light will
flash at a slower rate to indicate that the system is armed.
NOTE:If the SECURITY light stays on continuously
during vehicle operation, have the system checked by an
authorized dealer.
To Disarm the System:
Use the RKE transmitter to UNLOCK the door. If some-
thing has triggered the system in your absence, the horn
will sound three times when you unlock the doors and
the SECURITY light will flash for 30 seconds. Check the
vehicle for tampering.
The Security Alarm System will also disarm if the vehicle
is started with a programmed Sentry Keyt. If an unpro-
grammed Sentry Keytis 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 UNLOCK button, or start the vehicle with a
programmed Sentry Keyt.The 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 Security Alarm System
will not arm.ILLUMINATED ENTRY SYSTEM Ð 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
Keyless Entry.
The lights will fade to off after about 30 seconds, or they
will immediately fade to off once the ignition switch is
turned ON.

WARNING!
²For personal security and safety in the event of an
accident, lock the vehicle doors when you drive as
well as when you park and leave the vehicle.
²Never leave children alone in a vehicle. Leaving
unattended children in a vehicle is dangerous for a
number of reasons. A child or others could be
seriously or fatally injured. Don't leave the keys in
the ignition. A child could operate power win-
dows, other controls, or move the vehicle.
Power Door Locks Ð If Equipped
A power door lock switch is on each front door trim
panel. Use this switch to lock or unlock the doors.If you press the power door lock switch while the key is
in the ignition, and any front door is open, the power
locks will not operate. This prevents you from acciden-
tally locking your keys in the vehicle. Removing the key
or closing the door will allow the locks to operate. A

Here are some simple steps you can follow to minimize
the risk of harm from a deploying airbag.
1. Children 12 years and under should always ride
buckled up in a rear seat in an appropriate child restraint.
Infants in rear-facing child restraints shouldNEVERride
in the front seat of a vehicle with a passenger front airbag,
unless the airbag is turned off(2500/3500 Regular Cab
Vehicles Only). An airbag deployment can cause severe
injury or death to infants in that position. See the
Passenger Airbag ON/OFF Switch section.
You should read the instructions provided with your
child restraint to make sure that you are using it properly.
2. If your vehicle does not have a rear seat, see the
Passenger Airbag ON/OFF Switch section.
3.
Children that are not big enough to properly wear the
vehicle seat belt (see section on Child Restraints) should be
secured in the rear seat in child restraints or belt-positioningbooster seats. Older children who do not use child restraints
or belt-positioning booster seats, should ride properly buck-
led up in the rear seat. Never allow children to slide the
shoulder belt behind them or under their arm.
4. All occupants should use their lap and shoulder belts
properly.
5. The driver and front passenger seats should be moved
back as far as practical to allow the airbag room to inflate.
6. If your vehicle has window bags, do not lean against
the door or window, airbags will inflate forcefully into
the space between you and the door.
7. If the airbag system in this vehicle needs to be
modified to accommodate a disabled person, contact the
Customer Center. Phone numbers are provided in the9If
You Need Customer Assistance9section later in this
owner's manual.

Child Restraint
Everyone in your vehicle needs to be buckled up all the
time Ð babies and children, too. Every state in the United
States and all Canadian provinces require that small
children ride in proper restraint systems. This is the law,
and you can be prosecuted for ignoring it.
Children 12 years and younger should ride properly
buckled up in a rear seat, if available. According to crash
statistics, children are safer when properly restrained in
the rear seats rather than in the front.
