SECURITY ALARM SYSTEM — IF EQUIPPED
This system monitors the vehicle doors and ignition for
unauthorized operation. When the alarm is activated, the
system provides both audible and visual signals. For the
first 3 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 telltale
will flash. The engine will run only if a valid Sentry Key
is used to start the vehicle. Use of the Sentry Key will
disable the alarm.
Rearming of the System:
The security system will rearm itself after the 15 addi-
tional 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 remaining doors
and ignition.
To Set the Alarm:
The alarm will set when you use the power door locks,
turn the key in the driver’s door lock cylinder, or use the
Keyless Entry 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
your dealer.

To Disarm the System:
Use the Keyless Entry transmitter or the key to turn the
driver’s door lock to the unlock position. If something
has triggered the system in your absence, the horn will
sound three times when you unlock the doors and the
security lamp will flash for 30 seconds. Check the vehicle
for tampering.
The Security system 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 2 seconds and then the security alarm will be
initiated. To exit alarming mode, press the transmitter
Unlock button, unlock the driver’s door using the key
cylinder, or start the vehicle with a programmed Sentry
Key.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 transmitter, the alarm
will sound when you pull the door handle to exit. You
may also accidentally disarm the system by unlocking
the driver’s door with the door key and then locking it
manually with the lock plunger. The door will be locked
but the Security Alarm will not arm.
