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 1-29orInfants and Young Children on page 1-32. 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 so you can sit up straight. To see
how, see ªSeatsº in the Index.
1-14
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 1-14.
The right front passenger's safety belt works the same
way as the driver's safety belt Ð except for one
thing. If you ever pull the lap 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 Front Passenger Position
Lap Belt
If your vehicle has a front bench seat, someone can sit
in the center position.
When you sit in the center front seating position, you
have a lap safety belt, which has no retractor. To make
the belt longer, tilt the latch plate and pull it along the belt.

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 shoulder 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 seat. 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. Remove the guide from its storage pocket on the
top of the seatback.
1-26
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 next to a
window so the child can wear a lap-shoulder belt and
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.
1-29
{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 sitting in a seat next to a window,
move the child toward the center of the vehicle.
If the child is sitting in the center rear seat
passenger 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 sitting in a rear seat outside position,
see
Rear Safety Belt Comfort Guides for Children
and Small Adults on page 1-26
.
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.
1-30
Infants and Young Children
Everyone in a vehicle needs protection! This includes
infants and all other children. Neither the distance
traveled nor the age and size of the traveler changes
the need, for everyone, to use safety restraints. In fact,
the law in every state in the United States and in
every Canadian province says children up to some age
must be restrained while in a vehicle.
Every time infants and young children ride in vehicles,
they should have the protection provided by appropriate
restraints. Young children should not use the vehicle's
adult safety belts alone, unless there is no other choice.
Instead, they need to use a child restraint.
{CAUTION:
People should never hold a baby in their arms
while riding in a vehicle. A baby doesn't weigh
much Ð until a crash. During a crash a baby
will become so heavy it is not possible to hold
CAUTION: (Continued)
