REMOTE STARTING SYSTEM — IF EQUIPPED

This system uses the key fob to start the engine conve-
niently from outside the vehicle while still maintaining
security. The system has a range of approximately 300 ft (91
m).

NOTE:
• The vehicle must be equipped with an automatic trans-

mission to be equipped with Remote Start.

GETTING TO KNOW YOUR VEHICLE

SENTRY KEY

The Sentry Key Immobilizer System prevents unauthor-
ized 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 key fobs that have an embedded electronic
chip (transponder) to prevent unauthorized vehicle opera-
tion. Therefore, only key fobs that are programmed 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 fob that has not been programmed is also

considered an invalid key, even if it is cut to fit the ignition
or lock cylinder for that vehicle.

During normal operation, after placing the ignition in the
on position, 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 ten seconds), 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.

CAUTION!

The Sentry Key Immobilizer system is not compatible
with some aftermarket remote starting systems. Use of
these systems may result in vehicle starting problems
and loss of security protection.

All of the key fobs provided with your new vehicle have
been programmed to the vehicle electronics.

Replacement Key Fobs

NOTE:

Only key fobs that are programmed to the vehicle

electronics can be used to start and operate the vehicle.
Once a key fob is programmed to a vehicle, it cannot be
programmed to any other vehicle.

CAUTION!

Always remove the Sentry Keys from the vehicle and
lock all doors when leaving the vehicle unattended.

GETTING TO KNOW YOUR VEHICLE

Duplication of key fobs may be performed at an authorized
dealer or by following the customer key programming
procedure. This procedure consists of programming a
blank key fob to the vehicle electronics. A blank key fob is
one that has never been programmed.

NOTE:

When having the Sentry Key Immobilizer System

serviced, bring all vehicle key fobs with you to an autho-
rized dealer.

Customer Key Programming

If you have two valid key fobs, you can program new key
fobs to the Sentry Key Immobilizer system by performing
the following procedure:

1. Cut the additional key(s) to match the ignition and lock

cylinder key code.

2. Insert the first valid key into the ignition. Place the

ignition in the ON/RUN position for at least three
seconds, but no longer than 15 seconds. Then, place the
ignition in the LOCK position and remove the first key.

3. Insert the second valid key into the ignition. Place the

ignition in the ON/RUN position within 15 seconds.
After 10 seconds, a chime will sound. In addition, the

Vehicle Security Light will begin to flash. Place the
ignition in the LOCK position and remove the second
key.

4. Insert a blank key into the ignition. Place the ignition in

the ON/RUN position within 60 seconds. After 10
seconds, a single chime will sound. In addition, the
Vehicle Security Light will stop flashing. To indicate that
programming is complete, the Vehicle Security Light
will turn on again for three seconds and then turn off.

The new key is programmed. The key fob will also be
programmed during this procedure.

Repeat this procedure to program up to eight keys. If you
do not have a programmed key fob, contact your autho-
rized dealer for details.

NOTE:

If a programmed key fob is lost, see your autho-

rized dealer to have all remaining key fobs erased from the
system’s memory. This will prevent the lost key from
starting your vehicle. The remaining key fobs must then be
reprogrammed. All vehicle key fobs must be taken to an
authorized dealer at the time of service to be repro-
grammed.

VEHICLE SECURITY ALARM — IF EQUIPPED

The vehicle security alarm monitors the vehicle doors,
swing gate, and ignition for unauthorized operation. While
the vehicle security alarm is armed, interior switches for
door locks are disabled. The vehicle security alarm pro-
vides both audible and visible signals when alarming. The

horn will sound, the headlights will turn on, the park
lamps and/or turn signals will flash repeatedly for three
minutes. If the disturbance is still present (driver’s door,
passenger door, other doors, ignition) after three minutes,
the headlights, park lamps and/or turn signals will flash
for an additional 15 minutes.

NOTE:

The Panic Alarm and the vehicle security alarm are

quite different. Please take a moment to activate the Panic
Alarm and the vehicle security alarm to hear the differ-
ences in the horn. In case one should go off in the future,
you will need to know which mode has been activated in
order to deactivate it.

Rearming The System

If something triggers the alarm, and no action is taken to
disarm it, the vehicle security alarm will turn off the horn
after three minutes, turn off all of the visual signals after 15
minutes, and then the vehicle security alarm will rearm
itself.

GETTING TO KNOW YOUR VEHICLE

To Arm The System

The vehicle security alarm will set when you use the
Remote Keyless Entry key fob to lock the doors and swing
gate, or when you use the power door lock switch while
the door is open. After all the doors are locked and closed,
the vehicle security light (located on the instrument cluster)
will flash rapidly for about 16 seconds to signal that the
vehicle security alarm is arming. During this 16-second
arming period, opening any door or the swing gate will
cancel the arming. If the vehicle security alarm is success-
fully set, the vehicle security light will flash at a slower rate
to indicate the vehicle security alarm is armed.

To Disarm The System

To disarm the vehicle security alarm, you will need to push
the unlock button on the key fob, or turn the ignition
switch to the ON/RUN position. If something has trig-
gered the vehicle security alarm in your absence, the horn
will sound three times, and the exterior lights blink three
times when you unlock the doors. Check the vehicle for
tampering.

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 key fob, once the

vehicle security alarm is armed (after 16 seconds), when
you pull the door handle to exit, the alarm will sound. If
this occurs, push the unlock button on the key fob to
disarm the vehicle security alarm. You may also acciden-
tally disarm the vehicle security alarm by unlocking the
driver’s door with the key and then locking it. The door
will be locked but the vehicle security alarm will not arm.

NOTE:
• Unlocking the doors with the manual door lock plung-

ers or the driver’s door lock cylinder will not disarm the
vehicle security alarm.

• When the vehicle security alarm is armed, the interior

power door lock switches will not unlock the doors.
