GMC SIERRA 2010 Repair Manual

The person keeps going until stopped by something.
In a real vehicle, it could be the windshield...or the instrument panel...

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 is why
safety belts make such good sense.
Questions and Answers About
Safety Belts
Q: Will I be trapped in the vehicle after a crash if Iam wearing a safety belt?
A: You could be—whether you are wearing a safety
belt or not. But your chance of being conscious
during and after an accident, so you can unbuckle
and get out, is muchgreater if you are belted. And
you can unbuckle a safety belt, even if you are
upside down.
Q: If my vehicle has airbags, why should I have to wear safety belts?
A: Airbags are supplemental systems only; so they
work withsafety belts —not instead of them.
Whether or not an airbag is provided, all occupants
still have to buckle up to get the most protection.
That is true not only in frontal collisions, but
especially in side and other collisions.

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.
2-21

Sit up straight and always keep your feet on the floor
in front of you. 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 would be less likely to slide under the lap belt.
If you slid under it, the belt would apply force on 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 shoulder belt locks if there is a sudden stop or
crash.

Q: What is wrong with this?
A:The shoulder belt is too loose. It will not give as
much protection this way.
{WARNING:
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 snugly against your body.
2-23

Q: What is wrong with this?
A:The lap belt is too loose. It will not give nearly as
much protection this way.
{WARNING:
You can be seriously hurt if your lap belt is too
loose. In a crash, you could slide under the lap
belt and apply force on your abdomen. This could
cause serious or even fatal injuries. The lap belt
should be worn low and snug on the hips, just
touching the thighs.
2-24

Q: What is wrong with this?
A:The belt is buckled in the wrong buckle.
{WARNING:
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 on the pelvic bones. This
could cause serious internal injuries. Always
buckle your belt into the buckle nearest you.
2-25

Q: What is wrong with this?
A:The belt is over an armrest.
{WARNING:
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 on the abdomen,
not on the pelvic bones, and that could cause
serious or fatal injuries. Be sure the belt goes
under the armrests.
2-26

Q: What is wrong with this?
A:The shoulder belt is worn under the arm. It should
be worn over the shoulder at all times.
{WARNING:
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 are not as strong as shoulder bones.
You could also severely injure internal organs like
your liver or spleen. The shoulder belt should go
over the shoulder and across the chest.
2-27

Q: What is wrong with this?
A:The belt is behind the body.
{WARNING:
You can be seriously injured by not wearing the
lap-shoulder belt properly. In a crash, you would
not be restrained by the shoulder belt. Your body
could move too far forward increasing the chance
of head and neck injury. You might also slide
under the lap belt. The belt force would then be
applied right on the abdomen. That could cause
serious or fatal injuries. The shoulder belt should
go over the shoulder and across the chest.
