SECURITY ALARM SYSTEM — IF EQUIPPED
This system monitors the vehicle doors, swing gate, and
ignition for unauthorized operation. When the alarm is
activated, the system provides both audible and visible
signals. The horn, headlights, and tail lights will sound/
flash repeatedly for three minutes. If disturbance is still
present (driver’s door, passenger door, other doors, igni-
tion) after three minutes, the headlights and tail lights
will flash for an additional 15 minutes.
NOTE:The Panic and Security alarms are quite differ-
ent. Please take a moment to activate the Panic and the
Security modes to hear the differences 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.
To Set the Alarm
The alarm will set when you use the remote keyless entry
(RKE) transmitter 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
Sentry Key/Security Alarm Indicator Light (located on
the instrument cluster) will flash rapidly for about 16
seconds to signal that the system is arming. During this
16–second arming period, opening any door or the swing
gate will cancel the arming. If the system successfully
arms, the Sentry Key/Security Alarm Indicator Light
will flash at a slower rate to indicate the alarm is set.
To Disarm the System
To disarm the system, you will need to press the UN-
LOCK button on the RKE transmitter, or turn the ignition
key to the ON position. If something has triggered the
system in your absence, the horn will sound three times
when you unlock the doors. Check the vehicle for tam-
pering.

pressing the LOCK/UNLOCK button on the key fob.

Pressing the LOCK button while you are inside
of the vehicle will activate the Security Alarm. Opening a
door with the Security Alarm activated will cause the
alarm to sound. Press the UNLOCK button to deactivate
the Security Alarm.

Programming Additional Transmitters
Vehicles will be shipped from the assembly plants with
two key fob transmitters programmed only for that
vehicle. A total of eight key fobs can be programmed for
your vehicle. Additional key fobs can be programmed to
your vehicle through the use of a currently programmed
fob.
NOTE:When entering the program mode using that
key fob, all other programmed key fobs will be erased
and you will have to reprogram them for your vehicle.
Use the following procedure to program additional key
fobs if the vehicle is not equipped with a Sentry Key:
1. Enter the vehicle and close all of the doors.
2. Fasten your seat belt (Fastening the seat belt will
cancel any chiming that may confuse you during this
programming procedure).
3. Place the ignition key into the ignition. 4. Turn the ignition to the ON position.
Do not start the
engine.
5. Press and hold the UNLOCK button.
6. After holding the UNLOCK button for four seconds,
also press the PANIC button within six seconds.
7. When a single chime is heard, release both buttons.
The chime is an indication that you have successfully
entered program mode. All key fobs that are to be
programmed must be done so within 60 seconds of when
the chime was heard.
8. Using the key fob to be programmed, press and
release both the LOCK and UNLOCK buttons, simulta-
neously.
9. A single chime will be heard.
10. Within four seconds of hearing the chime, press and
release the UNLOCK button.
