Reinstalling the Rear Seats
{Warning
A seat that is not 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.
{Warning
A seat 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 seat 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. Locate the hole in the rail to install the locking pins at the rear of the seat base.
If the vehicle is equipped with a vinyl
floor covering, pull the flap that has
been cut into the vinyl.
3. Insert the locking pins into the seat base and push the seat to line up the pins
with the base.
On a three-passenger seat, the pin with
the black cap marked “R”must be
installed on the right side and the pin
with the gray cap marked “L”must be
installed on the left side.
On a four-passenger seat, the pins
marked “R”must be installed on the half
of the seat on the right side. The pins
marked “L”must be installed on the half
of the seat on the left side.

Seats and Restraints 31
Lap-Shoulder Belt
All seating positions in the vehicle have a
lap-shoulder belt. If you are using a rear
seating position with a detachable seat belt
and the seat belt is not attached, see
“Reinstalling the Rear Seats”underRear
Seats 024 for instructions on reconnecting
the seat belt to the mini-buckle.
The following instructions explain how to
wear a lap-shoulder belt properly.
1. Adjust the seat, if the seat is adjustable, so you can sit up straight. To see how,
see “Seats” in the Index.
2. 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.
If the shoulder portion of a passenger
belt is pulled out all the way, the child
restraint locking feature may be
engaged. See Child Restraint Systems
0 49. If this occurs, let the belt go back
all the way and start again. If the
locking feature stays engaged after
letting the belt go back to stowed position on the seat, move the seat
rearward or recline the seat until the
shoulder belt retractor lock releases.
3. 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 Seat Belt Extender 035.
Position the release button on the buckle
so that the seat belt could be quickly
unbuckled if necessary.
4. If equipped with a shoulder belt height adjuster, move it to the height that is
right for you. See “Seat belt Height Adjuster”
later in this section for
instructions on use and important safety
information.5. To make the lap part tight, pull up on the shoulder belt.
It may be necessary to pull stitching on
the seat belt through the latch plate to
fully tighten the lap belt on smaller
occupants.

32 Seats and Restraints
To unlatch the belt, push the button on the
buckle. The belt should return to its stowed
position. Slide the latch plate up the seat
belt webbing when the seat belt is not in
use. The latch plate should rest on the
stitching on the seat belt, near the guide
loop on the side wall.
Always stow the seat belt slowly. If the seat
belt webbing returns quickly to the stowed
position, the retractor may lock and cannot
be pulled out. If this happens, pull the seat
belt straight out firmly to unlock the
webbing, and then release it. If the webbing
is still locked in the retractor, see your
dealer.Before a door is closed, be sure the seat belt
is out of the way. If a door is slammed
against a seat belt, damage can occur to
both the seat belt and the vehicle.
Seat Belt Height Adjuster
The vehicle has a seat belt height adjuster
for the driver and front outboard passenger
positions.
Adjust the height so the shoulder portion of
the belt is on the shoulder and not falling
off of it. The belt should be close to, but not
contacting, the neck. Improper shoulder belt
height adjustment could reduce the
effectiveness of the seat belt in a crash. See
How to Wear Seat Belts Properly
029.
Squeeze both sides of the release button
and pull outward. Then move the height
adjuster up or down to the desired position
and release the button.
After the adjuster is set to the desired
position, try to move it up or down without
squeezing the release button to make sure it
has locked into position.
Seat Belt Pretensioners
If the vehicle has seat-mounted side impact
airbags and roof-rail airbags, it also has seat
belt pretensioners for the front outboard
occupants.
Although the seat belt pretensioners cannot
be seen, they are part of the seat belt
assembly. They can help tighten the seat
belts during the early stages of a moderate
to severe frontal, near frontal, or rear crash
if the threshold conditions for pretensioner
activation are met. And, if the vehicle has
roof-rail airbags, seat belt pretensioners can
help tighten the seat belts in a side crash or
a rollover event.
Pretensioners work only once. If the
pretensioners activate in a crash, the
pretensioners and probably other parts of
