3. After 30 seconds the alarm system will arm, and the indicator light will begin to
slowly flash indicating the alarm system
is operating. Pressing

the 30-second delay and immediately
arm the alarm system.
The vehicle alarm system will not arm if the

will chirp and the lights will flash to indicate
pre-alarm. If the vehicle is not started,
or the door is not unlocked by pressing

30 seconds. The alarm system will then
re-arm to monitor for the next unauthorized
event.

How to Detect a Tamper Condition

Immobilizer
See Radio Frequency Statement 0335.
Immobilizer Operation
This vehicle has a passive theft-deterrent
system.
The system does not have to be manually
armed or disarmed.
The vehicle is automatically immobilized
when the vehicle is turned off.
The immobilization system is disarmed
when the ignition is on or in accessory
mode and a valid transmitter is present in
the vehicle.
The security light in the instrument cluster
comes on if there is a problem with arming
or disarming the theft-deterrent system.
The system has one or more RKE
transmitters matched to an immobilizer
control unit in the vehicle. Only a correctly
matched RKE transmitter will start the
vehicle. If the transmitter is ever damaged,
the vehicle may not start. When trying to start the vehicle, the
security light may come on briefly when the
ignition is turned on.
If the engine does not start and the security
light stays on, there is a problem with the
system. Turn the ignition off and try again.
If the vehicle will not change ignition
modes, and the RKE transmitter appears to
be undamaged, try another transmitter. Or,
try placing the transmitter in the
transmitter pocket located in the center
console. See Starting the Vehicle With a Low
Transmitter Battery under
Remote Key
Operation (Mechanical Key) 010 or
Remote Key Operation (Remote Key) 013.
If the ignition mode will not change with
the other transmitter or with a transmitter
in the transmitter pocket, the vehicle needs
service. If the ignition does change modes,
the first transmitter may be faulty. See a
dealer who can service the theft-deterrent
system and have a new RKE transmitter
programmed to the vehicle.
It is possible for the immobilizer system
to learn new or replacement RKE
transmitters. Up to eight transmitters can be
programmed for the vehicle. To program
additional transmitters, see Programming
