Manual Seats
This section tells you about the seats – how to adjust
them, and fold them up and down.

adjust a manual driver’s seat while the vehicle
is moving. The sudden movement could startle
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.Move the lever located under the front of a manual seat
up to unlock it. Slide the seat to where you want it
and release the lever. Try to move the seat with your
body to make sure the seat is locked into place.

Turn the knob counterclockwise to increase lumbar
support and clockwise to decrease lumbar support.

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

To return the seatback to the upright position, push the
seatback all the way back until the latch catches. If

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.

Q:If I’m a good driver, and I never drive far from
home, why should I wear safety belts?
A:You may be an excellent driver, but if you’re in an
accident – even one that isn’t your fault – you and
your passengers can be hurt. Being a good
driver doesn’t protect you from things beyond your
control, such as bad drivers.
Most accidents occur within 25 miles (40 km) of
home. And the greatest number of serious injuries
and deaths occur at speeds of less than
40 mph (65 km/h).
Safety belts are for everyone.
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 1-31
orInfants and Young Children on page 1-34. Follow
those rules for everyone’s protection.
First, you’ll want to know which restraint systems your
vehicle has.
We’ll start with the driver position.
Driver Position
This part describes the driver’s restraint system.
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.
