WARNING
- Ignition key
Leaving children unattended in a
vehicle with the ignition key is dan-
gerous even if the key is not in the
ignition switch. Children copy
adults and they could place the key
in the ignition switch. The ignition
key would enable children to oper-
ate power windows or other con-
trols, or even make the vehicle
move, which could result in serious
bodily injury or even death. Never
leave the keys in your vehicle with
unsupervised children.
WARNING
Use only HYUNDAI original parts
for the ignition key in your vehicle.
If an aftermarket key is used, the
ignition switch may not return to
ON after START. If this happens,
the starter will continue to operate
causing damage to the starter
motor and possible fire due to
excessive current in the wiring.

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

use.
Your immobilizer system is comprised of
a small transponder in the ignition key
and electronic devices inside the vehicle.
With the immobilizer system, whenever
you insert your ignition key into the igni-
tion 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 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.
Otherwise the engine may not start or
may stop soon after it starts. Keep each
key separate in order to avoid a starting
malfunction.
✽NOTICEIf you need additional keys or lose your
keys, consult an authorized HYUNDAI

key is an important part of the immobilizer system. It is designedto give years of trouble-free service, however you should avoid expo-sure to moisture, static electricity and rough handling. Immobilizersystem malfunction could occur.

vehicle, do not leave spare keys
anywhere in your vehicle. Your
Immobilizer password is a cus-
tomer unique password and should

cle.
