Vehicle Security
This vehicle has theft-deterrent
features; however, they do not make
the vehicle impossible to steal.
Vehicle Alarm System
This vehicle has an anti-theft alarm
system.
The indicator light, on the
instrument panel near the
windshield, indicates the status of
the system:

bypass the 30-second delay
and immediately arm the alarm
system. The vehicle alarm system will not
arm if the doors are locked with

How to Detect a Tamper
Condition
IfKis pressed on the RKE
transmitter and the horn chirps and
the lights flash 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.
See Security Messages 0143.
Immobilizer
See Radio Frequency
Statement 0406.
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 transmitter
leaves the vehicle.
The immobilization system is
disarmed when the ignition button is
pushed in and a valid transmitter is
found in the vehicle.
The security light in the instrument
cluster comes on when there is a
problem with arming or disarming
the theft-deterrent system.
The system has one or more
transmitters matched to an
immobilizer control unit in your
vehicle. Only a correctly matched
transmitter will start the vehicle.
If the transmitter is ever damaged,
you may not be able to start your
vehicle.
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
vehicle off and try again.
If the RKE transmitter appears to be
undamaged, try another transmitter.
Or, you may try placing the
transmitter in the transmitter pocket
in the front cupholder. See “Starting
the Vehicle with a Low Transmitter
Battery” underRemote Keyless
Entry (RKE) System Operation 026.
