Front Seats
Manual Passenger Seat
Your vehicle may have a manual passenger seat. To
adjust the seat, lift the bar under the front of the seat to
unlock it. Slide the seat to where you want it and
release the bar. Try to move the seat back and forth
with your body to be sure the seat is locked in place.
Power Seats
If your vehicle is equipped with power front seats, the
controls are located on the outboard sides of the front
seat cushions.
Move the front of the horizontal control up or down to
raise or lower the front portion of the cushion.
Move the rear of the horizontal control up or down to
raise or lower the rear portion of the cushion.
Lift up or push down on the center of the horizontal
control to move the entire seat up or down.
To move the seat forward or rearward, slide the
horizontal control forward or rearward.

the seatback in place. To return the seatback to the
upright position, pull up on the lever without pushing on
the seatback.If your vehicle has power reclining front seatbacks, the
control is located on the outboard side of the front seats.

Use the following steps to lower one or both of the rear
seatbacks:
1. Insert a tool with a small
tip into the slot as
shown to unlatch the
seatbelt buckle. Then
move the belt to the
side so it is not in
your way.2. There is a tab located
on the outboard sides
of the seatback. Pull
forward on the tab to
unlock the seatback.
3. Fold the seatback down. This will allow you direct
access to the trunk.

4. Repeat Steps 2 and 3 to fold down the other
seatback.
{CAUTION:
If the seatback is not locked, it could move
forward in a sudden stop or crash. That could
cause injury to the person sitting there. Always
press rearward on the seatback to be sure it is
locked.
{CAUTION:
A safety belt that is improperly routed, not
properly attached, or twisted will not provide
the protection needed in a crash. The person
wearing the belt could be seriously injured.
After raising the rear seatback, always check
to be sure that the safety belts are properly
routed and attached, and are not twisted.To return the seatback to the upright position, do the
following:
1. Lift the seatback up and push it back into place.
2. Reconnect the center
safety belt latch plate to
the buckle as shown.
3. Make sure the seatback is locked into place by
pushing and pulling on it.
4. Repeat Steps 1 and 3 for the other seatback.
When the seatback is not in use, it should be kept in
the upright, locked position.

Q:If my vehicle has airbags, why should I have to
wear safety belts?
A:Airbags are in many vehicles today and will be in
most of them in the future. But they are
supplemental systems only; so they workwith
safety belts — not instead of them. Every airbag
system ever offered for sale has required the use of
safety belts. Even if you are in a vehicle that has
airbags, you still have to buckle up to get the most
protection. That is true not only in frontal collisions,
but especially in side and other collisions.
Q:If I am a good driver, and I never drive far from
home, why should I wear safety belts?
A:You may be an excellent driver, but if you are in an
accident — even one that is not your fault — you
and your passengers can be hurt. Being a good
driver does not protect you from things beyond your
control, such as bad drivers.
Most accidents occur within 25 miles (40 km) of
home. And the greatest number of serious injuries
and deaths occur at speeds of less than 40 mph
(65 km/h).
Safety belts are for everyone.
How to Wear Safety Belts Properly
This part is only for people of adult size.
Be aware that there are special things to know about
safety belts and children. And there are different
rules for smaller children and babies. If a child will be
riding in your vehicle, seeOlder Children on page 1-29
orInfants and Young Children on page 1-32. Follow
those rules for everyone’s protection.
First, you will want to know which restraint systems your
vehicle has.
We will start with the driver position.
Driver Position
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 “Seats” in the Index.
1-14
Page 21 of 432
3. Pick up the latch plate and pull the belt across you.
Do not let it get twisted.
The 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, seeSafety Belt
Extender on page 1-28.
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.5. To make the lap part tight, pull down on the buckle
end of the belt as you pull up on the shoulder belt.
1-15

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.
