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 accessory mode and a
valid remote key 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
remote keys matched to an
immobilizer control unit in your
vehicle. Only a correctly
matched remote key will startthe vehicle. If the remote key
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 (accessory
mode, on, off), and the remote
key appears to be undamaged,
try another remote key. Or,
you may try placing the
remote key in the remote key
pocket located in the center
console. See Remote Key
Operation
09.
If the ignition mode will not
change with the other remote
key or in the remote key
pocket, your vehicle needs
service. If the ignition does
change modes, the first
remote key may be faulty. See your dealer who can service
the theft-deterrent system
and have a new remote key
programmed to the vehicle.
It is possible for the
immobilizer system to learn
new or replacement remote
keys. Up to eight remote keys
can be programmed for the
vehicle. To program additional
remote keys, see
“Programming Remote Keys to
the Vehicle”
under Remote
Key Operation 09.
Do not leave the remote key
or device that disarms or
deactivates the
theft-deterrent system in the
vehicle.
