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.

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.
