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.

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.

move the head restraint after the button is
released to make sure that it is locked in
place.The front seat outboard head restraints are
not removable.

button, located on the top of the seatback,
and push the head restraint down.
When an occupant is in the seat, always
return the head restraint to the upright
position. Pull the head restraint up and push
