Q:If I am 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 are
in an accident — even one that is not your
fault — you and your passengers can be hurt.
Being a good driver does not 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
Older Children on page 39orInfants and Young
Children on page 42. Follow those rules for
everyone’s protection.
First, you will want to know which restraint
systems your vehicle has.
We will start with the driver position.
Driver Position
Lap-Shoulder Belt
The driver has a lap-shoulder belt. Here is 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.

To unlatch the belt, push the button on the buckle.
The belt should go back out of the way. When
the safety belt is not in use, slide the latch plate up
the safety belt webbing. The latch plate should
rest on the stitching on the safety belt, near
the guide loop on the side wall.
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.
Shoulder Belt Height Adjustment
Before you begin to drive, move the shoulder belt
height adjuster to the height that is right for you.
Adjust the height so that the shoulder portion of the
belt is centered on your shoulder. The belt should
be away from your face and neck, but not falling off
your shoulder. Improper shoulder belt height
adjustment could reduce the effectiveness of the
safety belt in a crash.
To move it down, press
the release button (A)
and move the height
adjuster to the desired
position. You can move
the height adjuster up
just by pushing up on the
shoulder belt guide.
After you move the height adjuster to where you
want it, try to move it down without pressing the
release button to make sure it has locked into
position.
