starting the engine. Only keys registered
with your vehicle’ s immobilizer system
can be used to operate your vehicle. If
engine start is attempted with an unregis-
tered access key fob or key, the engine
will not start. Even if the engine does start,
it will stop after a few seconds. This
system, however, is not a 100% anti-theft
guarantee.NOTE To protect your ve hicle from theft,
please pay close attention to the
following security precautions: - Never leave your vehicle unat-
tended with its keys inside. - Before leaving your vehicle,

close all windows and lock the
doors.

record of your key number in the
vehicle.

you ever need a replacement key made.
Any new key must be registered for use
with your vehicle’ s immobilizer system
before it can be used. The maximum
number of keys that can be registered for
use with one vehicle is seven.
One key that has already been registered
is required in order to register a new key.NOTEIf you lose a key, the lost key’s ID code
still remains in the memory of the vehi-
cle’s immobilizer system. For security
reasons, the lost key’s ID code should
be erased from the memory. To erase
the lost key’s ID code, all keys that will
be used are required. For details about new key registration

and erasing the lost key’s ID code,
