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.
~~
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 the split bench seat and bucket
seats fold forward to let you access the rear of the cab.

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.
And it explains the air bag system.
’
A CAUTION:
I
- -
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. 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.
Why Safety Belts Work
When you ride in or on anything, you go as fast as
it goes.
After more than
30 years of safety belts in vehicles,
the facts are clear. In most crashes buckling up does
matter
... a lot!
Take the
simplest vehicle. Suppose it’s just a seat
on wheels.

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.
Here Are Questions Many People Ask
About Safety Belts -- and the Answers
Won’t I be trapped in the vehicle after an
accident if I’m wearing a safety belt?
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,
so
you can unbuckle and get out, is much greater if
you are belted.
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 with
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 stili 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
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
control9 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
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.
