Manual Seats
The bucket seats can be adjusted forward or rearward
with the lever located at the front of the seat.To adjust the seat, pull the lever up to release the seat
bottom. Slide the seat to where you want it and then
release the lever. Try to move the seat with your body,
to make sure the seat is locked into place.
{CAUTION:
You can lose control of the vehicle if you try to
adjust a manual driver’s seat while the vehicle
is moving. The sudden movement could startle
and confuse you, or make you push a pedal
when you don’t want to. Adjust the driver’s
seat only when the vehicle is not moving.

Replacing the Rear Seats
{CAUTION:
A seat that isn’t locked into place properly can
move around in a collision or sudden stop.
People in the vehicle could be injured.
Be sure to lock the seat into place properly
when installing it.
{CAUTION:
A safety belt that is improperly routed, not
properly attached, or twisted won’t 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.1. Position the seat into the open slots in both rails.
Push the seat forward in the rail, hooking both
seat bases onto the pins inside of the rails.
2. To install the locking pins at the rear of the seat
base, locate the hole in the rail for the pin. It is
found on the inboard side of the seat. If the vehicle
hasfloor mats, pull theflap that has been cut
into the mat.
3. Insert the black or white locking pin into the seat
base. Possible slight seat pushing may be needed
to line up the pin with the base. Remember,
each pin has its own side. The pin with the white
handle marked“R”must be installed on the
passenger’s side and the pin with the black handle
marked“L”on the driver’s side.
4. Push the pin with the white handle marked“R”
down until it is in the retaining clip.

5. Push the pin with the black handle marked“R”
down until it is in the retaining clip.6. If the vehicle has afloor mat, put theflap back to
its original position.
7. Repeat this procedure for the other seat base.
8. Connect the quick-release latch plates for the
lap-shoulder belts by inserting the latch plates
into the buckles attached at the outboard positions
of the bench seat. Do not twist the belt.
9. Check that both locking pins are locked into place
before operating the vehicle.

Q:If I’m 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’re in an
accident–even one that isn’t your fault–you and
your passengers can be hurt. Being a good
driver doesn’t 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.
Howto 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 1-33
orInfants and Young Children on page 1-36. Follow
those rules for everyone’s protection.
First, you’ll want to know which restraint systems your
vehicle has.
We’ll start with the driver position.
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“Seats”in the Index.

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’d 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’s a sudden stop or crash.
Shoulder Belt Height Adjuster
Before you begin to drive, move the shoulder belt
adjuster to the height that is right for you.
To move it down, pull on
the center adjuster control
labeled PULL. You can
move the adjuster up just
by pushing up on the
shoulder belt guide.
After you move the adjuster to where you want it, try to
move it down without pushing in to make sure it has
locked into position.
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 1-14.
The right front passenger’s safety belt works the same
way as the driver’s safety belt—except for one
thing. If you ever pull the shoulder 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.
Center Passenger Position
(2nd Row)
If your vehicle has a second row bench seat, someone
can sit in the center position. When you sit in the
center position in the second row bench seat, you have
a lap-shoulder belt which works the same way as the
rear seat outside passengers’belts. To learn how
to wear a lap-shoulder belt see,“Lap-Shoulder Belt”
underRear Seat Passengers on page 1-26.
