If you suspect your smart key might
have sustained some damage, or
you feel your smart key is not work-
ing correctly, contact an authorized
HYUNDAI dealer.
Information
An inappropriately disposedbattery can be harmful to the
environment and human
health. Dispose of the battery
according to your local law(s)
or regulations.
Immobilizer System
(if equipped)
The immobilizer system protects
your vehicle from theft. If an improp-
erly coded key (or other device) is
used, the engine's fuel system is dis-
abled.
When the ignition switch is placed in
the ON position, the immobilizer sys-
tem indicator should come on briefly,
then go off. If the indicator starts to
blink, the system does not recognize
the coding of the key. Place the ignition switch to the
LOCK/OFF position, then place the
ignition switch to the ON position
again.
The system may not recognize your
key's coding if another immobilizer
key or other metal object (i.e., key
chain) is near the key. The engine
may not start because the metal may
interrupt the transponder signal from
transmitting normally.
If the system repeatedly does not
recognize the coding of the key, it is
recommended that you contact your
HYUNDAI dealer.
Do not attempt to alter this system or
add other devices to it. Electrical
problems could result that may make
your vehicle inoperable.
The transponder in your key is an
important part of the immobilizer
system. It is designed to give
years of trouble-free service, how-
ever you should avoid exposure to
moisture, static electricity and
rough handling. Immobilizer sys-
tem malfunction could occur.
Information
This device complies with Part 15 of
the FCC rules.
Operation is subject to the following
three conditions:
1. This device may not cause harmful
interference, and
2. This device must accept any inter- ference received, including interfer-
ence that may cause undesired

If the key is removed from the ignition
switch or placed in the ACC position
or the LOCK/OFF position with the

ver’s door is opened and closed, the
headlights are turned off after 15
seconds. Also, with the engine off if

closed, the headlamps (and/or park-
ing lamps) are turned off after 15

the lock button on the remote key or
smart key twice or turning the light
switch to the OFF or AUTO position.
You can activate or deactivate the
Headlamp Delay function from the

Display" section in this chapter. If the driver exits the vehicle
through another door besides the
driver door, the battery saver func-
tion does not operate and the
headlamp delay function does not
turn OFF automatically.
This may cause the battery to dis-
charge. To avoid battery dis-
charge, turn OFF the headlamps
manually from the headlamp
switch before exiting the vehicle.
