If you suspect your smart key might
have sustained some damage, or
you feel your smart key is not work-
ing correctly, it is recommended that
you contact a HYUNDAI authorised
repairer.
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.
Immobiliser system
The immobiliser 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 immobiliser sys-
tem indicator should come on briefly,
then go off. If the indicator starts to
blink, the system does not recognise
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 recognise your
key’s coding if another immobiliser
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
recognise the coding of the key, it is
recommended that you contact a
HYUNDAI authorised repairer. 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 immobiliser
system. It is designed to give
years of trouble-free service, how-
ever you should avoid exposure to
moisture, static electricity and
rough handling. Immobiliser sys-
tem malfunction could occur.
NOTICE
iIn order to prevent theft of your
vehicle, do not leave spare keys
anywhere in your vehicle. Your
immobiliser password is a cus-
tomer unique password and
should be kept confidential.
