Immobilizer system
(if equipped)
Your vehicle is equipped with an
electronic engine immobilizer system
to reduce the risk of unauthorized
vehicle use.
Your immobilizer system is com-
prised of a small transponder in the
ignition key and electronic devices
inside the vehicle.
With the immobilizer system, when-
ever you insert your ignition key into
the ignition switch and turn it to ON,
it checks and determines and verifies
if the ignition 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 sys-tem:
Turn the ignition key to the OFF posi-
tion. The immobilizer system acti-
vates automatically. Without a valid
ignition key for your vehicle, the
engine will not start.
To deactivate the immobilizersystem:
Insert the ignition key into the key
cylinder and turn it to the ON position.
✽ ✽ NOTICE
When starting the engine, do not use
the key with other immobilizer keys
around. Otherwise the engine may
not start or may stop soon after it
starts. Keep each key separate in
order to avoid a starting malfunction.
✽ ✽NOTICE
If you need additional keys or lose
your keys, contact an authorized
HYUNDAI dealer.
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
Do not put metal accessories
near the ignition switch.
Metal accessories may interruptthe transponder signal and mayprevent the engine from beingstarted.
