Smart key precautions
The smart key may not work if any of the
following occur:
• The smart key is close to a radio
transmitter such as radio station or
airport that may interfere with normal
operation of the transmitter.
• The smart key is near a mobile two way
radio system or a mobile phone.
• Another vehicle's smart key is being
operated close to your vehicle.
• If your windows are tinted, especially
with metallic window tint, it may cause
frequency interference, reducing the
smart key operating range.
• The vehicle battery is discharged.
• Connecting an external device to the
power outlet and placing the smart key
near the external device.
If the smart key does not work correctly,
open and close the door with the
mechanical key. To start the engine, press
the Button Start ignition switch directly
with the smart key. If you have a problem
with the smart key, contact an authorized
HYUNDAI dealer.
If the smart key is in close proximity to
your mobile phone, the signal could be
blocked by your mobile phone's
operational signals. This is specifically
relevant when the phone is active such as
making and receiving calls, text
messaging, and/or sending/receiving
emails. If possible, avoid keeping the
smart key and your mobile phone in the
same location such as pants or jacket
pocket to avoid interference between the
two devices.
