Head Restraints
Adjust your head restraint so that the top of the restraint
is closest to the top of your head. This position
reduces the chance of a neck injury in a crash.The switches used to
adjust the front head
restraints are located on
the outboard side of
each front seat.
Use the vertical power seat switch to move a front seat
head restraint up or down. Pull up or push down on
the switch to move the head restraint up or down.
Moving the head restraint also changes the height of
the shoulder belt.
The head restraints tilt forward and rearward also.
To tilt the head restraints forward, grasp the top of the
restraint and move it forward to where you want it
to go until you hear a click. It will then be locked into
that position until you need to move it again. Pulling
forward past the last position will allow the restraint to
return to an upright position.
The rear head restraints are adjustable, also. They tilt
forward and rearward like the front head restraints,
but they do not move up and down.

Driver Position
This part describes the driver's restraint system.
Lap-Shoulder Belt
The driver has a lap-shoulder belt. Here is 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.
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.
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 is not long enough, see
Safety Belt
Extender on page 1-23.
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.

The lap part of the belt should be worn low and snug on
the hips, just touching the thighs. In a crash, this
applies force to the strong pelvic bones. And you would
be less likely to slide under the lap belt. If you slid
under it, the belt would apply force at your abdomen.
This could cause serious or even fatal injuries. The
shoulder belt should go over the shoulder and across
the chest. These parts of the body are best able to take
belt restraining forces.
The safety belt locks if there is a sudden stop or crash,
or if you pull the belt very quickly out of the retractor.
Shoulder Belt Height Adjuster
Before you begin to drive, move the shoulder belt
adjuster to the height that is right for you. Adjust the
height so that the shoulder portion of the belt is centered
on your shoulder. The belt should be away from your
face and neck, but not falling off your shoulder.

The best way to protect the fetus is to protect the
mother. When a safety belt is worn properly, it's more
likely that the fetus won't be hurt in a crash. For
pregnant women, as for anyone, the key to making
safety belts effective is wearing them properly.
Right Front Passenger Position
To learn how to wear the right front passenger's safety
belt properly, seeDriver Position on page 1-12.
The right front passenger's safety belt works the same
way as the driver's safety belt Ð except for one
thing. If you ever pull the lap portion of the belt out all
the way, you will engage the child restraint locking
feature. If this happens, just let the belt go back all the
way and start again.
Rear Seat Passengers
It's very important for rear seat passengers to buckle
up! Accident statistics show that unbelted people in the
rear seat are hurt more often in crashes than those
who are wearing safety belts.
Rear passengers who aren't safety belted can be
thrown out of the vehicle in a crash. And they can strike
others in the vehicle who are wearing safety belts.

{CAUTION:
You can be seriously hurt if your shoulder belt
is too loose. In a crash, you would move
forward too much, which could increase injury.
The shoulder belt should ®t against your body.

4. Buckle the belt. Make sure the release button is
positioned so you would be able to unbuckle the
safety belt quickly if you ever had to.5. Pull the rest of the lap belt all the way out of the
retractor to set the lock.
