Vehicle Security This vehicle has theft-deterrent
features; however, they do not make
the vehicle impossible to steal.
Vehicle Alarm System
The indicator light, on the
instrument panel near the
windshield, indicates the status of
the system.
Off : Alarm system is disarmed.
On Solid : Vehicle is secured
during the delay to arm the system. Fast Flash : Vehicle is unsecured.
A door or the hood is open.
Slow Flash : Alarm system is
armed.
Arming the Alarm System 1. Turn off the vehicle.
2. Lock the vehicle in one of
two ways:
.
Use the RKE transmitter.
.
With a door open, press
Qon the interior of the door.
3. After 30 seconds, the alarm
system will arm and the
indicator light will begin to
slowly flash. Pressing
Q on the
RKE transmitter a second time
will bypass the 30-second
delay and immediately arm the
alarm system.
The vehicle alarm system will not
arm if the doors are locked with
the key.
If the driver door is opened without
first unlocking with the RKE
transmitter, the horn 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
K on the RKE
transmitter during the 10-second
pre-alarm, the alarm will be
activated.
The alarm will also be activated if a
passenger door or the hood is
opened without first disarming the
system. When the alarm is
activated, the turn signals flash and
the horn sounds for about
30 seconds. The alarm system will
then re-arm to monitor for the next
unauthorized event.
Disarming the Alarm System To disarm the alarm system or turn
off the alarm if it has been activated:
.
Press
K on the RKE transmitter.
.
Start the vehicle.
To avoid setting off the alarm by
mistake:

Keys, Doors, and Windows 55.
Always unlock a door with the
RKE transmitter.
Unlocking the driver door with
the key will not disarm the
system or turn off the alarm.
How to Detect a Tamper
Condition If
K is pressed on the RKE
transmitter and the horn chirps three
times, an alarm occurred previously
while the alarm system was armed.
If the alarm has been activated, a
message will appear on the DIC.
Immobilizer See Radio Frequency Statement
0 443 .
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 system is automatically
disarmed when the ignition is turned
from off to on.
The security light, in the instrument
cluster, comes on if there is a
problem with arming or disarming
the theft-deterrent system.
When trying to start the vehicle, the
security light comes 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 (ACC/ACCESSORY, on, off),
and the RKE transmitter appears to
be undamaged, try another
transmitter. Or, you may try placing the transmitter in the transmitter
pocket in the center console. See
Keys 0 30 .
If the ignition modes will not change
with the other transmitter or in the
transmitter pocket, your vehicle
needs service. If the ignition does
change modes, the first transmitter
may be faulty. See your 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 a new or
replacement transmitter. Up to eight
transmitters can be programmed for
the vehicle.
Do not leave the transmitter or
device that disarms or deactivates
the vehicle theft system in the
vehicle.
When equipped with a key, if the
engine still does not start, and the
key appears to be undamaged, try
another ignition key. It may be
necessary to check the fuse. See
Fuses and Circuit Breakers 0 350 .
