Information
An inappropriately disposedbattery can be harmful to the
environment and human health.
Dispose of the battery according
to your local law(s) or regula-
tions.
Immobilizer System
(if equipped)
The immobilizer system protects your
vehicle from theft. If an improperly
coded key (or other device) is used,
the engine's fuel system is disabled.
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 transpon-
der 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
operation.
3. Changes or modifications not expressly approved by the party
responsible for compliance could
void the user’s authority to operate
the device.

In order to prevent theft of your
vehicle, do not leave spare keys
