Information

Immobilizer system

The immobilizer system helps protect
your vehicle from theft. If an improperly
ODN8059266 ODN8059266
coded key (or other device) is used, the
vehicle is disabled.
When the Start/Stop button is pressed to
the ON position, the immobilizer system
indicator should come on briefly, then
go off. If the indicator starts to blink, the
system does not recognize the coding of
the key.
Press the Start/Stop button to the OFF
position, then press the Start/Stop
button to the ON position again.
In some circumstances, the vehicle may
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.
If the system repeatedly does not
recognize the coding of the key, it is
recommended that you contact an
authorized HYUNDAI dealer.
Do not attempt to alter this system
or add other devices to it. Electrical
problems could result that may make
your vehicle inoperable.
An inappropriately disposed
battery can be harmful to
the environment and human
health. Dispose of the battery
according to your local law(s) or
regulations.
