accident:
Lock the vehicle after all
occupants have left the vehicle
and all doors are closed.

RKE transmitter or use the Keyless
Access system.

the alarm.
How to Detect a Tamper
Condition
If is pressed on the RKE
transmitter and the horn chirps and
the lights flash three times, a previous
alarm occurred while the system was
armed.

message will appear on the DIC. See
Security Messages 0 144.
Power Sounder and Inclination
Sensor
In addition to the standard
theft-deterrent system features, this
system may also have a power
sounder and inclination sensor.
The power sounder provides an
audible alarm which is distinct from
the vehicle s horn. It has its own
power source, and can sound an alarm
if the vehicle s battery is
compromised.
The inclination sensor can set off the
alarm if it senses movement of the
vehicle, such as a change in vehicle
orientation.

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 pushbutton start
is activated to enter the ACC/
ACCESSORY mode or the ON/RUN/
START 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,
you may not be able to start your
vehicle.
