The Immobilizer System protects
your vehicle from theft. If an
improperly coded key (or other
device) is used, the engine's fuel
system is disabled.
When you turn the ignition switch to
the ON (II) position, the immobilizer
system indicator should come on
briefly, then go off. If the indicator
starts to blink, it means the system
does not recognize the coding of the
key. Turn the ignition switch to the
LOCK (0) position, remove the key,
reinsert it, and turn the ignition
switch to the ON (II) position again.
The system may not recognize your
key's coding if another immobilizer
key or other metal object (i.e. key
chain) is near the ignition switch
when you insert the key.If the system repeatedly does not
recognize the coding of your key,
contact your dealer.
Do not attempt to alter this system or
add other devices to it. Electrical
problems could result that may make
your vehicle inoperable.
If you have lost your key and you
cannot start the engine, contact your
dealer.
Always take the ignition key with you
whenever you leave the vehicle alone.This device complies with the
appropriate requirements or the
required standards. See page 592 for
more information.
