Immobilizer System
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 transponder signal from
transmitting normally.
If the system repeatedly does not
recognize the coding of the key, con-
tact your HYUNDAI dealer.
