Immobilizer system
Your vehicle may be equipped with
an electronic engine immobilizer sys-
tem to reduce the risk of unautho-
rized vehicle use.
Your immobilizer system is com-
prised of a small transponder in the
key and electronic devices inside the
vehicle.
Whenever the engine start/stop but-
ton is changed to the ON position,
the immobilizer system checks and
verifies if the key is valid or not.
If the key is valid, the engine will
start.
If the key is invalid, the engine will
not start.
To deactivate the immobilizer
system
Change the engine start/stop button
to the ON position.
To activate the immobilizer system
Change the engine start/stop button
to the OFF position. The immobilizer
system activates automatically.
Without a valid smart key for your
vehicle, the engine will not start.
WARNING
In order to prevent theft of your
vehicle, do not leave spare keys
anywhere in your vehicle. Your
immobilizer password is a cus-
tomer unique password and
should be kept confidential. Do
not leave this number anywhere
in your vehicle.
CAUTION
Keep the smart key away from
water or any liquid and fire. If
the inside of the smart key gets
damp (due to drinks or mois-
ture), or is heated, internal cir-
cuit may malfunction, excluding
the car from the warranty.
