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.

system to learn a new or
replacement transmitter. Up to eight
transmitters can be programmed for
the vehicle.

device that disarms or deactivates
the vehicle theft system in the

key appears to be undamaged, try
another ignition key. It may be
necessary to check the fuse. See
