Immobilizer System

The immobilizer system protects
your vehicle from theft. If an improp-
erly coded key (or other device) is
used, the power system is disabled.
When the POWER button is placed
in 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.
Place the POWER button to the OFF
position, then place the POWER but-
ton 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
and human
additional keys near the smart key
before attempting to start the vehicle
again.
