Seats and Seat Controls
This section tells you about the seats -- how to adjust
them, and fold them up and down. It also tells you about
reclining front seatbacks and head restraints.
Manual Front Seat
CAUTION:
You can lose control of the vehicle if you try to
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
don't want to. Adjust the driver's seat only when
the vehicle is not moving.
You can adjust the seat
with this lever located at
the front of the seat.
Slide the lever toward the passenger's side to unlock the
seat. Using your body, slide the seat to where you want
it. Then, release the lever and try to move the seat with
your body in order to make sure the seat is locked
into place.

1-3 Power Lumbar Control (If Equipped)
If you have power lumbar
adjustment, you can
increase or decrease
lumbar support in an area
of the lower seatback.
To increase support, press and hold the front of the
rocker switch. Let go of the switch when the lower
seatback reaches the desired level of support.
To decrease support, press and hold the rear of the
rocker switch. Let go of the switch when the lower
seatback reaches the desired level of support.
Reclining Seatbacks
To adjust the front seatback, move the lever rearward.
Release the lever to lock the seatback where you want it.
Move the lever again rearward and the seatback will go
to an upright position.

1-4
But don't have a seatback reclined if your vehicle
is moving.
CAUTION:
Sitting in a reclined position when your vehicle is
in motion can be dangerous. Even if you buckle
up, your safety belts can't do their job when
you're reclined like this.
The shoulder belt can't do its job because it
won't be against your body. Instead, it will be
in front of you. In a crash you could go into it,
receiving neck or other injuries.
The lap belt can't do its job either. In a crash the
belt could go up over your abdomen. The belt
forces would be there, not at your pelvic bones.
This could cause serious internal injuries.
For proper protection when the vehicle is in
motion, have the seatback upright. Then sit well
back in the seat and wear your safety belt properly.

1-5 Head Restraints
Slide the head restraint up or down so that the top of the
restraint is closest to the top of your ears. This position
reduces the chance of a neck injury in a crash.
Seatback Latches
The front seatback folds forward to let you access
the rear of the cab. To fold the seatback, pull the easy
entry lever located on the outboard side of the seat.
To return the seatback to the upright position, push the
seatback rearward until it latches. Then it will be locked
into place.
CAUTION:
If the seatback isn't 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.

Safety Belts: They're for Everyone
This part of the manual tells you how to use safety belts
properly. It also tells you some things you should not do
with safety belts.
CAUTION:
Don't let anyone ride where he or she can't wear
a safety belt properly. If you are in a crash and
you're not wearing a safety belt, your injuries
can be much worse. You can hit things inside the
vehicle or be ejected from it. You can be seriously
injured or killed. In the same crash, you might
not be if you are buckled up. Always fasten your
safety belt, and check that your passengers' belts
are fastened properly too.
CAUTION:
It is extremely dangerous to ride in a cargo area,
inside or outside of a vehicle. In a collision,
people riding in these areas are more likely to be
seriously injured or killed. Do not allow people
to ride in any area of your vehicle that is not
equipped with seats and safety belts. Be sure
everyone in your vehicle is in a seat and using a
safety belt properly.
Your vehicle has a light
that comes on as a reminder
to buckle up. See ªSafety
Belt Reminder Lightº in
the Index.

In most states and Canadian provinces, the law says to
wear safety belts. Here's why: They work.
You never know if you'll be in a crash. If you do have
a crash, you don't know if it will be a bad one.
A few crashes are mild, and some crashes can be so
serious that even buckled up a person wouldn't survive.
But most crashes are in between. In many of them,
people who buckle up can survive and sometimes
walk away. Without belts they could have been badly
hurt or killed.
After more than 30 years of safety belts in vehicles,
the facts are clear. In most crashes buckling up does
matter ... a lot!Why Safety Belts Work
When you ride in or on anything, you go as fast as it goes.
Take the simplest vehicle. Suppose it's just a seat
on wheels.
