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 remote key.
If the remote key does not work
correctly, open and close the door
with the mechanical key. If you have
a problem with the remote key, it is
recommended that you contact an
authorized HYUNDAI dealer.
If the remote key is in close proximity to
your mobile phone, the signal could be
blocked by your mobile phone's normal
operational signals.
This is specifically relevant 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 location and
always try to maintain an adequate
distance between the two devices.

approved by the party responsible

to changes or modifications not expressly
approved by the party responsible for
compliance, it will not be covered by your
manufacturer's vehicle warranty.
NOTICE
Keep the remote key away from
electromagnetic materials that block
electromagnetic waves to the key
surface.
