Manual Seats
{CAUTION:
You can lose control of the vehicle if you try to

and confuse you, or make you push a pedal
when you do not want to. Adjust the driver’s
seat only when the vehicle is not moving.
Lift the bar located under the front of the seat to unlock
it. Slide the seat to where you want it and release
the bar. Try to move the seat with your body to make

Seatback Latches
Your vehicle may be equipped with front seatbacks that
fold forward to let people get into the rear seat or to
access the storage area behind the seat.
To fold the front seatback
forward, push the lever on
the side of the seat
rearward and pull the
seatback forward.
{CAUTION:
If the seatback is not locked, it could move
forward in a sudden stop or crash. That
could cause injury to the person sitting there.
Always press rearward on the seatback to
be sure it is locked.To return the seatback to the upright position, push the
seatback all the way back until the latch catches. If
the seatback was reclined before being folded forward,
it will return to the reclined position.
Rear Seats
Rear Seat Operation (Crew Cab)
If your vehicle is a crew cab, the rear seatback can be
folded forward. Before you can fold the rear seatback,
you need to unlatch the center safety belt buckle.
Use the following steps to lower one or both of the rear
seatbacks:
1. Insert a tool with a small tip into the slot to unlatch
the center position safety belt buckle. Then move
the belt to the side so it is not in the way.

2. Grasp the loop located
on the side of the
seatback you want to
fold and pull until
you hear a click.
3. Fold the seatback down.
4. Repeat Steps 2 and 3 to fold down the other
seatback.
{CAUTION:
If the seatback is not locked, it could move
forward in a sudden stop or crash. That
could cause injury to the person sitting there.
Always press rearward on the seatback to be
sure it is locked.
{CAUTION:
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.
To return the seatback to the upright position, do the
following:
1. Lift the seatback up and push it back into place.
2. Reconnect the center safety belt latch plate to the
buckle.
3. Make sure the seatback is locked into place by
pushing and pulling on it.
4. Repeat Steps 1 and 3 for the other seatback.
When the seatback is not in use, it should be kept in
the upright, locked position.

How to 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 1-32
orInfants and Young Children on page 1-35. Follow
those rules for everyone’s protection.
First, you will want to know which restraint systems your
vehicle has.
We will start with the driver position.
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 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 1-31.
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.
1-17

5. Move the shoulder belt height adjuster to the height
that is right for you. SeeShoulder Belt Height
Adjustment on page 1-23.
6. To make the lap part tight, pull down on the buckle
end of the belt as you pull up on the shoulder belt.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,
or if you pull the belt very quickly out of the retractor.
