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
A 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.
If your vehicle has a manual
bucket, split bench
or full
bench seat, you can adjust it
with this lever at the front
of the seat.
Slide the lever at the front
of the seat toward the
passenger’s side to unlock it. 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.

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 of the base level bench seat folds
forward to let you access the rear of the cab. Your
seatback will move back and forth freely, unless you
come to a sudden stop. Then it will lock into place. If
you have
a Crew Cab, your front seatback is designed
not to fold forward. Access to the rear of the cab is
available by using the rear doors.
The front seatback
of split bench seat and bucket seats
fold forward to let you access the rear of the cab.
To fold a front split bench
or bucket seatback forward,
pull this lever forward and
fold the seatback forward.
To return the seatback to the upright position, just push
the seatback rearward until it latches. After returning the
seatback to its upright position, pull
the seatback
forward to make sure
it is locked.
The rear seatback of a rear bench seat without a center
armrest can be folded forward to let you reach the
area behind
it. Your seatback will move back and forth
freely, unless you come to
a sudden stop. Then, it will
lock into place.
The Crew Cab rear seatback
with a center armrest folds
forward to let you access
the area behind it.

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 “Safety
Belt Reminder Light” 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
25 years of safety belts in vehicles,
the facts are clear. In most crashes buckling up does
matter
... a lot!

How to Wear Safety Belts Properly
Adults
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, see the part of this manual called
“Children.” 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’s how to wear
it properly.
1. Close and lock the door.
2. Adjust the seat (to see how, see “Seats” in the Index)
so you can sit up straight.

3. Pick up the latch plate and pull the belt across you.
Don’t let it get twisted.
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 isn’t long enough, see “Safety Belt
Extender” at the end of this section.
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.

A child in a rearfacing child restraint can be
seriously injured if the right front passenger’s air
bag inflates. This is because the back of a rearfacing child restraint would be very close to
the inflating air bag. Always secure a rearfacing
child restraint in the rear seat.
You’ll be using the lap-shoulder belt. See the earlier part
about the top strap if the child restraint has one.
1. Because your vehicle has a right front passenger air
bag, always move the seat as far back as it will
go
before securing a forward-facing child restraint. (See
“Seats” in the Index.)
for the child restraint.
2. Put the restraint on the seat. Follow the instructions
4. Pick up the latch plate, and run the lap and shoulder
portions of the vehicle’s safety belt through or
around the restraint. The child restraint instructions
will show you how.
If the shoulder belt goes in front
of the child’s face or
neck, put it behind the child restraint.
3. Secure the child in the child restraint as the
instructions say.
5. Buckle the belt. Make sure the release button is
positioned
so you would be able to unbuckle the
safety belt quickly if you ever had to.
