Features of your vehicle
Immobilizer system (if equipped)Your vehicle is equipped with an elec-
tronic engine immobilizer system to

a small transponder in the ignition key
and electronic devices inside the vehicle.

you insert your ignition key into the igni-
tion switch and turn it to ON, it checks

key is valid.
If the key is determined to be valid, the
engine will start.
If the key is determined to be invalid, the
engine will not start.To activate the immobilizer system:Turn the ignition key to the OFF position.
The immobilizer system activates auto-
matically. Without a valid ignition key for
your vehicle, the engine will not start.To deactivate the immobilizer sys-tem:Insert the ignition key into the key cylin-
der and turn it to the ON position.
✽ ✽ NOTICEWhen starting the engine, do not use the
key with other immobilizer keys around.

key separate in order to avoid a starting
malfunction.
