Remote key precautions
The remote key will not work if any of
the following occur:
•The key is in the ignition switch.
•You exceed the operating distance
limit (about 30 m [90 feet]).
•The remote key battery is weak.
•Other vehicles or objects may be
blocking the signal.
•The weather is extremely cold.
•The remote key is close to a radio
transmitter such as a radio station
or an airport which can interfere
with normal operation of the

a problem with the remote key, it is
recommended that you contact an
authorised HYUNDAI dealer.

If the remote key is in close proximi-
ty to your mobile phone, the signal
could be blocked by your mobile
phone’s normal operational signals.
This is especially important when the
phone is active such as making and
receiving calls, text messaging,
and/or sending/receiving emails.
Avoid placing the remote key and
your mobile phone in the same loca-
tion and always try to maintain an
adequate distance between the two
devices.
