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

the system. Only an authorized key
starts the vehicle. The vehicle may
not start if the key is damaged.
The security light in the instrument
cluster comes on if there is a
problem with arming or disarming
the theft-deterrent system.
When trying to start the vehicle, the
security light comes on briefly when
the 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.
Do not leave the key or device that
disarms or deactivates the
theft-deterrent system in the vehicle.

52 Seats and Restraints
Lap-Shoulder Belt
All seating positions in the vehicle
have a lap-shoulder belt.
The following instructions explain
how to wear a lap-shoulder belt
properly.1. Adjust the seat, if the seat is adjustable, so you can sit up
straight. To see how, see
“Seats” in the Index.
2. Pick up the latch plate and pull
the 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. If this happens, let
the belt go back all the way
and start again.
For the driver and front
outboard passenger belts,
if the webbing locks in the latchplate before it reaches the
buckle, tilt the latch plate to flat
to unlock.
3. Push the latch plate into the
buckle until it clicks.
If the latch plate will not go fully
into the buckle, check if the
correct buckle is being used.
Pull up on the latch plate to
make sure it is secure. If the
belt is not long enough, see
Safety Belt Extender 055.
Position the release button on
the buckle so that the safety
belt could be quickly unbuckled
if necessary.
