times, an alarm occurred previously while
the alarm system was armed.
If the alarm has been activated, a message
will appear on the DIC.
Immobilizer
See Radio Frequency Statement 0271.
Immobilizer Operation
This vehicle has a passive theft-deterrent
system.
The system does not have to be manually
armed or disarmed.
The vehicle is automatically immobilized
when the transmitter leaves the vehicle. The immobilization system is disarmed
when POWER
Ois pressed and a valid
transmitter is found in the vehicle.
The security light on the instrument cluster
comes on when there is a problem with
arming or disarming the theft-deterrent
system.
The system has one or more transmitters
matched to an immobilizer control unit in
the vehicle. Only a correctly matched
transmitter will start the vehicle. If the
transmitter is damaged, you may not be
able to start the vehicle.
When trying to start the vehicle, the
security light comes on briefly when the
vehicle is turned on.
If the vehicle does not start and the security
light stays on, there is a problem with the
system. Turn the vehicle off and try again.

drive until the head restraints for all
occupants are installed and adjusted
properly.

Seats and Restraints 27
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 chance of a neck injury in a
crash.
Front Seats
The height of the head restraint can be
adjusted. To raise or lower the head
restraint, press the button located on the
side of the head restraint, and pull up or
push the head restraint down, and release
the button. Pull and push on 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.
Rear Seats
The vehicle’s rear seats have adjustable head
restraints in the outboard seating positions.
The height of the head restraint can be
adjusted.
Pull the head restraint up to raise it. Try to
move the head restraint to make sure it is
locked in place.
To lower the head restraint, press the
button on the top of the seatback and push
the head restraint down. Try to move the
head restraint after the button is released to
make sure it is locked in place.If installing a child restraint in the rear seat,
see
“Securing a Child Restraint Designed for
the LATCH System” underLower Anchors
and Tethers for Children (LATCH System)
0 55.
Folding the Rear Head Restraint
The head restraint can be folded rearward to
allow for better visibility when the rear seat
is unoccupied.To fold the head restraint, press the button
on the side of the head restraint.

0 52. If this occurs, let the belt go back
all the way and start again. If the
locking feature stays engaged after
letting the belt go back to stowed
position on the seat, move the seat
rearward or recline the seat until the
shoulder belt retractor lock releases.
Engaging the child restraint locking
feature in the front outboard seating
position may affect the passenger
sensing system. See Passenger Sensing
System 044.
3. Push the latch plate into the buckle until
it clicks. Pull up on the latch plate to make sure
it is secure. If the belt is not long
enough, see
Seat Belt Extender 037.
Position the release button on the buckle
so that the seat belt could be quickly
unbuckled if necessary.
4. To make the lap part tight, pull up on the shoulder belt.
To unlatch the belt, push the button on the
buckle. The belt should return to its stowed
position.
Always stow the seat belt slowly. If the seat
belt webbing returns quickly to the stowed
position, the retractor may lock and cannot
be pulled out. If this happens, pull the seat
belt straight out firmly to unlock the
webbing, and then release it. If the webbing
is still locked in the retractor, see your
dealer.
Before a door is closed, be sure the belt is
out of the way. If a door is slammed against
a seat belt, damage can occur to both the
seat belt and the vehicle.
