The Immobilizer System protects
your vehicle f rom thef t. A properly-

coded key (or other device) is used,
the engine’s f uel system is disabled.
When you turn the ignition switch to

indicator should come on f or a f ew
seconds, then go out. If the indicator
starts to blink, it means the system
does not recognize the coding of the
key. Turn the ignition switch to
LOCK (0), remove the key, reinsert
it, and turn the switch to ON (II)
again.The system may not recognize your
key’s coding if another immobilizer
key or other metal object is near the
ignition switch when you insert the
key. To make sure the system
recognizes the key code:
Do not keep other immobilizer
keys on the same key ring.
Use a plastic or leather key f ob,
not metal.
Keep other keys away f rom your
vehicle’s key and the ignition
switch while trying to start the
engine. If the system repeatedly does not
recognize the coding of your key,
contact your Acura dealer.
The Immobilizer System indicator
will also blink several times when
you turn the ignition switch f rom ON
(II) to ACCESSORY (I) or LOCK (0).
Do not attempt to alter this system
or add other devices to it. Electrical
problems could result that may make
your vehicle undriveable.
If you have lost your key and you
cannot start the engine, contact your
Acura dealer.
