system.
The system does not have to be manually
armed or disarmed.
The vehicle is automatically immobilized
when the key is removed from the ignition.

ignition is turned on.
If the engine does not start and the security
light stays on, there is a problem with the
system. Turn the ignition off and try again.
If the engine still does not start, and the
key appears to be undamaged or the light
continues to stay on, try another ignition
key. If the engine does not start with the
other key, the vehicle needs service. If the
vehicle does start, the first key may be
damaged. See your dealer who can service
the theft-deterrent system and have a new
key made.

Warning
With head restraints that are not
installed and adjusted properly, there is a
greater chance that occupants will suffer
a neck/spinal injury in a crash. Do not
drive until the head restraints for all
occupants are installed and adjusted
properly.
Adjust the head restraint so that the top of
the restraint is at the same height as the
top of the occupant's head. This position
reduces the chances of a neck injury in a
crash.
