But don't have a seatback reclined if your vehicle is
moving.
{CAUTION:
Sitting in a reclined position when your vehicle
is in motion can be dangerous. Even if you
buckle up, your safety belts can't do their job
when you're reclined like this.
The shoulder belt can't do its job because it
won't be against your body. Instead, it will be
in front of you. In a crash you could go into it,
receiving neck or other injuries.
The lap belt can't do its job either. In a crash
the belt could go up over your abdomen. The
belt forces would be there, not at your pelvic
bones. This could cause serious internal
injuries.
For proper protection when the vehicle is in
motion, have the seatback upright. Then sit
well back in the seat and wear your safety belt
properly.

Rear Seat Operation
Removing the Rear Seat

release latch plates for
the lap shoulder belts
on the bench seat to be
removed. To do this,
press the tip of a key
into the release hole of
the safety belt buckle
while pulling up on the
safety belt.
·There are two pins located on the inboard sides of
the rear seats. If the vehicle has ¯oor mats, the
pins will be located under a ¯ap that has been cut
into the mat. The driver's side pin will have a black
cap with an ªLº marked on it and will look like this:

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
has ¯oor mats, pull the ¯ap 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 ªRº must be installed on the
passenger's side and the pin with the black handle
marked ªLº on the driver's side.
4. Push the pin with the white handle marked ªRº
down until it is in the retaining clip.

5. Push the pin with the black handle marked ªRº
down until it is in the retaining clip.6. If the vehicle has a ¯oor mat, put the ¯ap 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.

Safety Belts
Safety Belts: They Are for Everyone
This part of the manual tells you how to use safety
belts properly. It also tells you some things you should
not do with safety belts.
{CAUTION:
Don't let anyone ride where he or she can't
wear a safety belt properly. If you are in a
crash and you're not wearing a safety belt,
your injuries can be much worse. You can hit
things inside the vehicle or be ejected from it.
You can be seriously injured or killed. In the
same crash, you might not be, if you are
buckled up. Always fasten your safety belt,
and check that your passengers' belts are
fastened properly too.
{CAUTION:
It is extremely dangerous to ride in a cargo
area, inside or outside of a vehicle. In a
collision, people riding in these areas are more
likely to be seriously injured or killed. Do not
allow people to ride in any area of your vehicle
that is not equipped with seats and safety
belts. Be sure everyone in your vehicle is in a
seat and using a safety belt properly.
Your vehicle has a light
that comes on as a
reminder to buckle up. See
Safety Belt Reminder
Light on page 3-26.
