PASSIVE ANTI-THEFT
SYSTEM
Principle of Operation
The system prevents someone from
starting the engine with an incorrectly
coded key.
Note: Do not leave correctly coded keys in
the vehicle. Always take your keys and lock
all doors when leaving the vehicle.
Coded Keys
If you lose a key, you can obtain a
replacement from an authorized dealer. If
possible, provide them with the key
number from the tag provided with the
original keys. You can also obtain extra
keys from an authorized dealer.
Note: Have all of your remaining keys
erased and recoded if you lose a key. Have
replacement keys coded together with
recoding your remaining keys. See an
authorized dealer for further information.
Note: Do not shield your keys with metal
objects. This may prevent the receiver from
recognizing a coded key.
Arming the Engine Immobilizer
When you switch the ignition off the engine
immobilizer will arm automatically after a
short time.
Disarming the Engine Immobilizer
When you switch the ignition on the engine
immobilizer will disarm automatically if a
correctly coded key is used.
If you are unable to start your vehicle with
a correctly coded key, have your vehicle
checked by an authorized dealer.
