located on the outboard side of the seat. Release the
lever to lock the seatback where you want it. Lift
the lever again without pushing on the seatback and the
seatback will go to an upright position.

see
Power Seats on page 1-4
for further information on
how to operate the reclining seatback feature.
1-6
But don’t have a seatback reclined if your vehicle is
moving.
{CAUTION:
Information Provided by:
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. 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.
Head Restraints
Adjust your head restraint so that the top of the restraint
is closest to the top of your head. This position
reduces the chance of a neck injury in a crash.
To raise the head restraint pull up on the head restraint.
On some models the head restraints tilt forward and
rearward also.
The rear seat head restraints in your vehicle may be
adjustable. They work the same as the front seat head
restraints, except they do not tilt forward and rearward.
1-7
Seatback Latches
Information Provided by:
Rear Seats
{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.
The seatbacks fold forward to let you access the rear of
the cab.
To fold a front seatback forward, lift the lever at the
base of the seat to release the seatback.
The lever is located on the outboard side of the seat
cushion.
To return the seatback to the upright position, push the
seatback rearward until it latches. After returning the
seatback to its upright position, push and pull on
the seatback to make sure it is locked.

Rear Seat Operation (Extended Cab)
Folding the Rear Seat
The extended cab’s rear seat can be folded up to
provide more cargo space. To fold the seat do the
following:
1. Pull forward on the
release strap located
under the rear seat
cushion.
2. Fold the seat cushion upward until it latches with
the seatback.
3. Push and pull on the seat to make sure the seat is
secure.
The extended cab’s rear seat can also be folded open
Information Provided by:
for more seating space. To use the seat do the following:
1. Push rearward on the seat cushion while pulling
up on the release strap under the seat cushion.
Pull the seat cushion downward until it latches.
2. After pulling the seat cushion down, pull up on it to
make sure it is locked.
Rear Seat Operation (Crew Cab)
The second row rear seat has a 60/40 split seat. Either
side of the rear seat may be folded down to give
you more cargo space.
Make sure that nothing is under or in front of the seat
and that the head restraints are completely lowered.
To fold the rear seat, do the following:
1. Pull up on the strap
loop at the rear of the
seat cushion. Then,
pull the seat cushion up
and fold it forward.
2. After folding the seat cushion fully forward, pull the
seatback forward and fold the seatback down until it
is flat. If the seatback cannot fold flat because it
interferes with the cushion, try moving the front seat
forward and/or bringing the front seat more
upright. The lever at the base of the seat must be
turned rearward to release the seatback.
To return the seat to the passenger position do the
following:
1. Lift the seatback up and push it rearward all
the way.
2. Lower the seat cushion until it latches into position.
3. Pull forward on the seatback and up on the seat
cushion to make sure the seat is securely in
place.
Check to see that the buckles on the driver’s side
seatback are accessible to the outboard and center
occupant and are not under the seat cushions.

Safety Belts
Information Provided by:
Safety Belts: They Are 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
Safety Belt Reminder
Light on page 3-36
In most states and in all Canadian provinces, the law
says to wear safety belts. Here’s why:

You never know if you’ll be in a crash. If you do have a
Information Provided by:
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.

Questions and Answers About
Information Provided by:
Safety Belts
Q: Won’t I be trapped in the vehicle after an
accident if I’m wearing a safety belt?
or the safety belts!
With safety belts, you slow down as the vehicle does.
You get more time to stop. You stop over more distance,
and your strongest bones take the forces. That’s why
safety belts make such good sense.
1-14
A: You
could
be – whether you’re wearing a safety
belt or not. But you can unbuckle a safety belt,
even if you’re upside down. And your chance
of being conscious during and after an accident,

Q: If my vehicle has air bags, why should I have to
wear safety belts?
A: Air bags are in many vehicles today and will be in
most of them in the future. But they are
supplemental systems only; so they work
safety belts – not instead of them. Every air bag
system ever offered for sale has required the
use of safety belts. Even if you’re in a vehicle that
has air bags, you still have to buckle up to get
the most protection. That’s true not only in frontal
collisions, but especially in side and other
collisions.

Q: If I’m a good driver, and I never drive far from
Information Provided by:
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, see
or
Infants and Young Children on page 1-34
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
Information Provided by:
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 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.
Don’t 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 isn’t long enough, see
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.
.

5. To make the lap part tight, pull down on the buckle
Information Provided by:
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’d 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’s a sudden stop or crash,
or if you pull the belt very quickly out of the retractor.
1-17
Q: What’s wrong with this?
Information Provided by:
A: The shoulder belt is too loose. It won’t give nearly
as much protection this way.
{CAUTION:
You can be seriously hurt if your shoulder belt
is too loose. In a crash, you would move
forward too much, which could increase injury.
The shoulder belt should fit against your body.
1-18
Q: What’s wrong with this?
Information Provided by:
A: The belt is buckled in the wrong place.
{CAUTION:
You can be seriously injured if your belt is
buckled in the wrong place like this. In a crash,
the belt would go up over your abdomen. The
belt forces would be there, not at the pelvic
bones. This could cause serious internal
injuries. Always buckle your belt into the
buckle nearest you.
1-19
Q: What’s wrong with this?
Information Provided by:
A: The belt is over an armrest.
{CAUTION:
You can be seriously injured if your belt goes
over an armrest like this. The belt would be
much too high. In a crash, you can slide under
the belt. The belt force would then be applied
at the abdomen, not at the pelvic bones, and
that could cause serious or fatal injuries. Be
sure the belt goes under the armrests.
1-20
Q: What’s wrong with this?
Information Provided by:
A: The shoulder belt is worn under the arm. It should
be worn over the shoulder at all times.
{CAUTION:
You can be seriously injured if you wear the
shoulder belt under your arm. In a crash, your
body would move too far forward, which would
increase the chance of head and neck injury.
Also, the belt would apply too much force to
the ribs, which aren’t as strong as shoulder
bones. You could also severely injure internal
organs like your liver or spleen.
1-21
Q: What’s wrong with this?
Information Provided by:
A: The belt is twisted across the body.
{CAUTION:
You can be seriously injured by a twisted belt.
In a crash, you wouldn’t have the full width of
the belt to spread impact forces. If a belt is
twisted, make it straight so it can work
properly, or ask your dealer to fix it.
1-22
To unlatch the belt, just push the button on the buckle.
Information Provided by:
The belt should go back out of the way.
Before you close the door, be sure the belt is out of the
way. If you slam the door on it, you can damage
both the belt and your vehicle.
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 don’t 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’s more
likely that the fetus won’t be hurt in a crash. For
pregnant women, as for anyone, the key to making
safety belts effective is wearing them properly.
1-23
Right Front Passenger Position
Information Provided by:
To learn how to wear the right front passenger’s safety
belt properly, see
The right front passenger’s safety belt works the same
way as the driver’s safety belt—except for one thing.
If you ever pull the shoulder portion of the belt out all the
way, you will engage the child restraint locking feature
which may turn off the passenger’s frontal air bag. If this
happens unintentionally, just let the belt go back all
the way and start again.
Driver Position on page 1-16
.
Center Passenger Position
If your vehicle has front and rear bench seats, someone
can sit in the center positions.
When you sit in the center rear seat position of a crew
cab you have a lap-shoulder belt which is similar to
the rear outside seat positions. To learn how to wear this
belt see “Lap-Shoulder Belt” under
Passengers on page 1-26
