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
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 1-34orInfants and Young Children on page 1-36. 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.

The best way to protect the fetus is to protect the
mother. When a safety belt is worn properly, it's more
likely that the fetus won't be hurt in a crash. For
pregnant women, as for anyone, the key to making
safety belts effective is wearing them properly.
Right Front Passenger Position
To learn how to wear the right front passenger's safety
belt properly, seeDriver Position on page 1-16.
The right front passenger's safety belt works the same
way as the driver's safety belt ± except for one thing.
If you ever pull the shoulder portion of the belt out all the
way, you will engage the child restraint locking feature.
If this happens, just let the belt go back all the way
and start again.
Center Passenger Position
(2nd Row)
If your vehicle has a second row bench seat, someone
can sit in the center position. When you sit in the
center position in the second row bench seat, you have
a lap-shoulder belt which works the same way as the
rear seat outside passengers' belts. To learn how
to wear a lap-shoulder belt see, ªLap-Shoulder Beltº
under
Rear Seat Passengers on page 1-28.

1. Pick up the latch plate and pull the belt across you.
Don't let it get twisted.
2. Push the latch plate into the buckle until it clicks.
Pull up on the latch plate to make sure it is secure.
When the shoulder belt is pulled out all the way
you will engage the child restraint locking feature. If
this happens, just let the belt go back all the way
and start again.If the belt is not long enough, see
Safety Belt
Extender on page 1-33.
Make sure the release button on the buckle is
positioned so you would be able to unbuckle the
safety belt quickly if you ever had to.
3. To make the lap part tight, pull down on the buckle
end of the belt as you pull up on the shoulder part.

Rear Safety Belt Comfort Guides for
Children and Small Adults
Your vehicle may have this feature already. If it doesn't,
you can get it from any GM dealer.
Rear safety belt comfort guides will provide added
safety belt comfort for older children who have outgrown
booster seats and for small adults. When installed on
a shoulder belt, the comfort guide better positions
the belt away from the neck and head.
There is one guide available for each outside passenger
position in the rear seats. To provide added safety
belt comfort for children who have outgrown child
restraints and booster seats and for smaller adults, the
comfort guides may be installed on the shoulder
belts. Here's how to install a comfort guide and use the
safety belt:
1. Locate the guide on the side of the seatback.

Child Restraints
Older Children
Older children who have outgrown booster seats should
wear the vehicle's safety belts.
If you have the choice, a child should sit in a seating
position that has a lap-shoulder belt to get the additional
restraint a shoulder belt can provide.
Q:What is the proper way to wear safety belts?
A:If possible, an older child should wear a
lap-shoulder belt and get the additional restraint a
shoulder belt can provide. The shoulder belt
should not cross the face or neck. The lap belt
should ®t snugly below the hips, just touching the
top of the thighs. It should never be worn over
the abdomen, which could cause severe or even
fatal internal injuries in a crash.
Accident statistics show that children are safer if they
are restrained in the rear seat.
In a crash, children who are not buckled up can strike
other people who are buckled up, or can be thrown
out of the vehicle. Older children need to use safety
belts properly.
1-34

{CAUTION:
Never do this.
Here two children are wearing the same belt.
The belt can't properly spread the impact
forces. In a crash, the two children can be
crushed together and seriously injured. A belt
must be used by only one person at a time.
Q:What if a child is wearing a lap-shoulder belt,
but the child is so small that the shoulder belt
is very close to the child's face or neck?
A:If the child is seated in a rear outside seat position,
move the child toward the center of the vehicle.
See
Rear Safety Belt Comfort Guides for Children
and Small Adults on page 1-31
. If the child is
sitting in the second row center seat position, move
the child toward the safety belt buckle. In either
case, be sure that the shoulder belt still is on the
child's shoulder, so that in a crash the child's
upper body would have the restraint that belts
provide. If the child is so small that the shoulder
belt is still very close to the child's face or
neck, you might want to place the child in a seat
that has a lap belt, if your vehicle has one.
