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 an
accident if I am wearing a safety belt?
A:Youcouldbe — whether you are wearing a
safety belt or not. But you can unbuckle a
safety belt, even if you are upside down. And
your chance of being conscious during and
after an accident, so youcanunbuckle and get
out, ismuchgreater if you are belted.
Q:If my vehicle has airbags, why should I
have to wear safety belts?
A:Airbags are in many vehicles today and will be
in most of them in the future. But they are
supplemental systems only; so they workwith
safety belts — not instead of them. Every
airbag system ever offered for sale has
required the use of safety belts. Even if you
are in a vehicle that has airbags, you 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.
26

Right Front Passenger Position
To learn how to wear the right front passenger’s
safety belt properly, seeDriver Position on
page 27.
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 which may turn off
the passenger’s frontal airbag. 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.

{CAUTION:
Children who are up against, or very close
to, any airbag when it inates can be
seriously injured or killed. Airbags plus
lap-shoulder belts offer protection for
adults and older children, but not for
young children and infants. Neither the
vehicle’s safety belt system nor its airbag
system is designed for them. Young
children and infants need the protection
that a child restraint system can provide.
49

{CAUTION:
A child can be seriously injured or killed
in a crash if the child is not properly
secured in the child restraint. Make sure
the child is properly secured, following
the instructions that came with that
restraint.
Because there are different systems, it is important
to refer to the instructions that come with the
restraint. A child can be endangered in a crash if
the child is not properly secured in the child
restraint.
Where to Put the Restraint
Accident statistics show that children are safer
if they are restrained in the rear rather than
the front seat.
We recommend that child restraints be secured in
a rear seat including an infant riding in a
rear-facing infant seat, a child riding in a
forward-facing child seat and an older child riding
in a booster seat.
Your vehicle may have a label on your sun visor
that says, “Never put a rear-facing child seat in the
front.” This is because the risk to the rear-facing
child is so great, if the airbag deploys.
Never put a child in a rear-facing child restraint in
the right front passenger seat unless your
vehicle has the passenger sensing system or an
airbag off switch and the passenger airbag
status indicator or the airbag off light shows off.
55

Never put a rear facing child restraint in the right
front passenger seat unless the airbag is off.
Here is why:
{CAUTION:
A child in a rear-facing child restraint can
be seriously injured or killed if the right
front passenger’s airbag inates. This is
because the back of the rear-facing child
restraint would be very close to the
inating airbag. Be sure the airbag is off
before using a rear-facing child restraint
in the right front seat position.
CAUTION: (Continued)
CAUTION: (Continued)
Even though the passenger sensing
system or airbag off switch are designed
to turn off the passenger’s frontal airbag
under certain conditions, no system is
fail-safe, and no one can guarantee that
an airbag will not deploy under some
unusual circumstance, even though it is
turned off. General Motors recommends
that rear-facing child restraints be
transported in vehicles with a rear seat
that will accommodate a rear-facing child
restraint, whenever possible.
If you need to secure a forward-facing
child restraint in the right front seat,
always move the front passenger seat as
far back as it will go. It is better to secure
the child restraint in a rear seat.
