and are not twisted.

Driver Position
This part describes the driver's restraint system.
Lap-Shoulder Belt
The driver has a lap-shoulder belt. Here's how to wear
it properly.
1. Close and lock the door.
2. Adjust the seat so you can sit up straight. To see
how, see ªSeatsº in the Index.
3. Pick up the latch plate and pull the belt across you.
Don't let it get twisted.
4. 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 isn't long enough, see ªSafety Belt
Extenderº at the end of this section.
Make sure the release button on the buckle is
positioned so you would be able to unbuckle the
safety belt quickly if you ever had to.

CAUTION:
Both frontal and side impact air bags inflate with
great force, faster than the blink of an eye. If
you're too close to an inflating air bag, as you
would be if you were leaning forward, it could
seriously injure you. Safety belts help keep you in
position for air bag inflation before and during a
crash. Always wear your safety belt, even with
frontal air bags. The driver should sit as far back
as possible while still maintaining control of the
vehicle. Front occupants should not lean on or
sleep against the door.
CAUTION:
Anyone who is up against, or very close to, any air
bag when it inflates can be seriously injured or killed.
Air bags plus lap
-shoulder belts offer the best
protection for adults, but not for young children and
infants. Neither the vehicle's safety belt system nor
its air bag system is designed for them. Young
children and infants need the protection that a child
restraint system can provide. Always secure children
properly in your vehicle. To read how, see the part
of this manual called ªChildren.º
There is an air bag
readiness light on the
instrument panel,
which shows the air
bag symbol.
The system checks the air bag electrical system for
malfunctions. The light tells you if there is an electrical
problem. See ªAir Bag Readiness Lightº in the Index
for more information.

2. Push the latch plate into the buckle until it clicks.
Pull up on the latch plate to make sure it is secure.
When the shoulder belt is pulled out all the way, it
will lock. If it does, let it go back all the way and
start again.
If the belt is not long enough, see ªSafety Belt
Extenderº at the end of this section.
Make sure the release button on the buckle is
positioned so you would be able to unbuckle the
safety belt quickly if you ever had to.
3. To make the lap part tight, pull down on the buckle
end of the belt as you pull up on the shoulder part.

CAUTION:
People should never hold a baby in their arms
while riding in a vehicle. A baby doesn't weigh
much
-- until a crash. During a crash a baby will
become so heavy it is not possible to hold it. For
example, in a crash at only 25 mph (40 km/h), a
12
-lb. (5.5 kg) baby will suddenly become a
240
-lb. (110 kg) force on a person's arms. A baby
should be secured in an appropriate restraint.
