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.

your keys, contact an authorized
HYUNDAI dealer.

Smart key precautions
The smart key will not work if any
of the following occur:
- The smart key is close to a radiotransmitter such as a radio sta-
tion or an airport which can inter-
fere with normal operation of the
smart key.
- The smart key is near a mobile two way radio system or a cellular
phone.
- Another vehicle's smart key is being operated close to your
vehicle.
When the smart key does not work correctly, open and close the door
with the mechanical key and con-
tact an authorized HYUNDAI deal-
er.
If the smart key is in close proximi- ty to your cell phone or smart
phone, the signal from the smart
key could be blocked by normal
operation of your cell phone or
smart phone. This is especially
important when the phone is active
such as making a call, receiving
calls, text messaging, and/or send-
ing/receiving emails. Avoid placing the smart key and
your cell phone or smart phone in
the same pants or jacket pocket
and maintain adequate distance
between the two devices.
In cold and wet climates, door lock and door mechanisms may not
work properly due to freezing con-
ditions.
If the door is locked/unlocked mul- tiple times in rapid succession with
either the vehicle key or door lock
switch, the system may stop oper-
ating temporarily in order to protect
the circuit and prevent damage to
system components.
