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.

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.
If the RKE transmitter appears to be
undamaged, try another transmitter,
or place the transmitter in the
transmitter pocket.
See
“Starting the Vehicle with a Low
Transmitter Battery” underRemote

transmitter placed in the transmitter
pocket, the vehicle needs service.
See your dealer who can service
the theft-deterrent system and have
a new transmitter programmed to
the vehicle.
Do not leave the transmitter or
device that disarms or deactivates
the theft-deterrent system in the
vehicle.

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 thehead restraint after the button is
released to make sure it is locked in
place.
If installing a child restraint in the

“Securing a Child
Restraint Designed for the LATCH
System” underLower Anchors and
Tethers for Children (LATCH
System) 066.

2. Pick up the latch plate and pullthe belt across you. Do not let
it get twisted.
The lap-shoulder belt may lock
if you pull the belt across you
very quickly. If this happens, let
the belt go back slightly to
unlock it. Then pull the belt
across you more slowly.
If the shoulder portion of a
passenger belt is pulled out all
the way, the child restraint
locking feature may be
engaged. See Child Restraint
Systems 063. 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 053.
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
045.
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.

A pregnant woman should wear a
lap-shoulder belt, and the lap
portion should be worn as low as
possible, below the rounding,
throughout the pregnancy.
The best way to protect the fetus is
to protect the mother. When a seat
belt is worn properly, it is more likely
that the fetus will not be hurt in a
crash. For pregnant women, as for
anyone, the key to making seat
belts effective is wearing them
properly.
Seat Belt Extender
If the vehicle's seat belt will fasten
around you, you should use it.
But if a seat belt is not long enough,
your dealer will order you an
extender. When you go in to order it,
take the heaviest coat you will wear,
so the extender will be long enough
for you. To help avoid personal
injury, do not let someone else use
it, and use it only for the seat it is
made to fit. The extender has been
designed for adults. Never use it for
securing child restraints. For more
information on the proper use and fit
of seat belt extenders see the
instruction sheet that comes with
the extender.
Safety System Check
Periodically check the seat belt
reminder, seat belts, buckles, latch
plates, retractors, shoulder belt
height adjusters (if equipped), and
seat belt anchorages to make sure
they are all in working order. Look
for any other loose or damaged seat
belt system parts that might keep aseat belt system from performing
properly. See your dealer to have it
repaired. Torn, frayed, or twisted
seat belts may not protect you in a
crash. Torn or frayed seat belts can
rip apart under impact forces. If a
belt is torn or frayed, have it
replaced immediately. If a belt is
twisted, it may be possible to
untwist by reversing the latch plate
on the webbing. If the twist cannot
be corrected, ask your dealer to
fix it.
Make sure the seat belt reminder
light is working. See
Seat Belt
Reminders 099.
Keep seat belts clean and dry. See
Seat Belt Care 045.
Seat Belt Care
Keep belts clean and dry.
Seat belts should be properly cared
for and maintained.
Seat belt hardware should be kept
dry and free of dust or debris. As
necessary, exterior hard surfaces
and seat belt webbing may be lightly
cleaned with mild soap and water.
