Folding the Rear Seat
Notice:Folding a rear seat with
the safety belts still fastened may
cause damage to the seat or the
safety belts. Always unbuckle
the safety belts and return them
to their normal stowed position
before folding a rear seat.
To fold the seat:
1. Pull up on the front of the seat cushion while pulling down on
the release strap under the seat
cushion.
2. Pull the seat cushion up until it latches with the seatback.
3. Pull forward on the seat cushion to make sure it is locked in
place. To unfold the seat:
1. Push the seat cushion rearward
while pulling the release strap
under the seat cushion. Pull
the seat cushion down until it
latches.
2. Pull up on the seat cushion to make sure it is locked in place.
Make sure the safety belts are
not twisted or caught in the seat
cushion.
{WARNING
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.

3-16 Seats and Restraints
First, before you or your
passenger(s) wear a safety belt,
there is important information you
should know.
Sit up straight and always keep
your feet on the floor in front of you.
The lap part of the belt should beworn 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 on 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 shoulder belt locks if there is a
sudden stop or crash.
Q: What is wrong with this?
A:
The shoulder belt is too loose.
It will not give as much
protection this way.

Lap-Shoulder Belt
If the vehicle is a regular cab,
then all seating positions in the
vehicle have a lap-shoulder belt.
If the vehicle is a crew or extended
cab, then all seating positions in
the vehicle have a lap-shoulder
belt except for the center front
passenger position (if equipped),
which has a lap belt. SeeLap Belt
(Crew and Extended Cab) on
page 3‑26 for more information.
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.
If this happens, let the belt go
back all the way and start again.
Engaging the child restraint
locking feature may affect the
passenger sensing system,
if equipped. See Passenger
Sensing System on page 3‑40
for more information.
If the belt stops before it reaches
the buckle, when using the
lap-shoulder belt in a rear center
seating position of a crew-cab,
tilt the latch plate and keep
pulling the safety belt until it
can be buckled.

Shoulder Belt Height Adjuster
The vehicle has a shoulder belt
height adjuster for the driver and
right front passenger.
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 safety belt in a crash. SeeHow
to Wear Safety Belts Properly on
page 3‑15.
Regular and Crew Cab
To move the adjuster down for the
regular and crew cabs, squeeze
the buttons (A) on the sides of the
height adjuster and move the height
adjuster to the desired position.Extended Cab
On the extended cab, push down
on the release button (A) and move
the height adjuster to the desired
position.
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 squeezing the buttons
for the regular and crew cabs,
or without pushing the release
button for extended cabs, to make
sure it has locked into position.
