The immobilizer system protects your
vehicle from theft. If an improperly coded
fuel system is disabled.
When the ignition switch is placed in the
ON position, the immobilizer system indi-
cator 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.
coding if another immobilizer key or oth-
er metal object (for example, 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 recog-
nize the coding of the key, it is recom-
mended 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.
