Q: If I am a good driver, and I never drive far fromhome, why should I wear safety belts?
A: You may be an excellent driver, but if you are in a
crash —even one that is not your fault —you and
your passenger(s) 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 section 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 infants. If a child will be riding in
the vehicle, see Older Children
on page 2‑39orInfants
and Young Childrenon page 2‑42. Follow those rules
for everyone's protection.
It is very important for all occupants to buckle up.
Statistics show that unbelted people are hurt more often
in crashes than those who are wearing safety belts.
Occupants who are not buckled up can be thrown out of
the vehicle in a crash. And they can strike others in the
vehicle who are wearing safety belts.
First, before you or your passenger(s) wear a safety
belt, there is important information you should know.

4. If equipped with a shoulder belt height adjuster,move it to the height that is right for you.
See “Shoulder Belt Height Adjustment” later in
this section.
5. To make the lap part tight, pull up on the shoulder belt.
It may be necessary to pull stitching on the safety
belt through the latch plate to fully tighten the lap
belt on smaller occupants.
To unlatch the belt, push the button on the buckle.
The belt should return to its stowed position.
Before a door is closed, be sure the safety belt is out
of the way. If a door is slammed against a safety belt,
damage can occur to both the safety belt and the
vehicle.

{WARNING:
A safety belt that is not properly worn may not
provide the protection needed in a crash.
The person wearing the belt could be seriously
injured. 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.
4. Buckle, position, and release the safety belt asdescribed previously in this section. Make sure that
the shoulder belt crosses the shoulder.
To remove and store the comfort guide, squeeze the
belt edges together so that the safety belt can be
removed from the guide. Slide the guide onto the
storage clip.
