coded key (or other device) is used, the
engine’s fuel system is disabled.

not recognize your smart key if another
smart key device is nearby or a metal
object such as a key chain is causing
interference with the smart key.
If this occurs, your vehicle may not
start. Remove any metal objects or
additional keys near the smart key before
attempting to start the vehicle again.

recognize the coding of the key, it is
recommended that you contact your
HYUNDAI dealer.

or add other devices to it. Electrical
problems could result that may make
your vehicle inoperable. WARNING

vehicle, do not leave spare keys
anywhere in your vehicle. Your

unique password and should be kept
confidential.
