Rear Seats
Rear Seat Operation (Full Bench)
Folding the Rear Seat
To fold the seat up, do the following:

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.
1. Pull up on the front
of the seat cushion
while pulling
down on the release
strap, located
under the seat
cushion.2. Pull the seat cushion up until it latches with
the seatback.
3. After latching the seat cushion up, pull
forward on it to make sure it is locked.

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.
3. 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.
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 44.
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. Move the shoulder belt height adjuster to the
height that is right for you. Improper shoulder
belt height adjustment could reduce the
effectiveness of the safety belt in a crash. See
Shoulder Belt Height Adjustment on page 35.
28

6. To make the lap part tight, pull up on the
shoulder belt.
It may be necessary to pull stitching on the
safety belt through the latch plate to fully
tighten the lap belt on smaller occupants.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.
29

On the extended cabs,
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.
Safety Belt Use During Pregnancy
Safety belts work for everyone, including pregnant
women. Like all occupants, they are more likely to
be seriously injured if they do not wear safety belts.A pregnant woman should wear a lap-shoulder
belt, and the lap portion should be worn as low
as possible, below the rounding, throughout
the pregnancy.
The best way to protect the fetus is to protect the
mother. When a safety belt is worn properly, it
is more likely that the fetus will not be hurt
in a crash. For pregnant women, as for anyone,
the key to making safety belts effective is wearing
them properly.
