0 380.
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 ACC/ACCESSORY 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 your
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.
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 (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 located in the center
console. See Remote Keyless Entry
(RKE) System Operation 08.

If the ignition mode 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 new or replacement
RKE transmitters. Up to eight
transmitters can be programmed for
the vehicle. To program additional
transmitters, see“Programming
Transmitters to the Vehicle” under
Remote Keyless Entry (RKE)
System Operation 08.
Do not leave the transmitter or
device that disarms or deactivates
