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.
37

{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.
56

{CAUTION:
A child in a child restraint in the center
front seat can be badly injured or killed by
the right front passenger’s airbag if it
inates. Never secure a child restraint in
the center front seat. It is always better to
secure a child restraint in the rear seat.
Do not use child restraints in the center front seat
position. The restraints will not work properly.
There is limited space in the rear seating area of
an extended cab model. If you want to secure
a child restraint in a rear seating position of
an extended cab model, especially in the rear
center position, be sure to study the instructions
that came with your child restraint to see if there is
enough room to secure your seat properly.If your vehicle has the passenger sensing system
or the airbag off switch and you need to secure
a rear-facing child restraint in the right front
passenger’s seat, the passenger’s frontal airbag
must be off. SeePassenger Sensing System
on page 103,Airbag Off Switch on page 100,
Securing a Child Restraint in the Right Front Seat
Position (Regular and Extended Cab) (With
Airbag Off Switch) on page 78orSecuring a Child
Restraint in the Right Front Seat Position
(Regular and Extended Cab) (With Passenger
Sensing System) on page 85for more on
this including important safety information.
Wherever you install a child restraint, be sure to
secure the child restraint properly.
Keep in mind that an unsecured child restraint can
move around in a collision or sudden stop and
injure people in the vehicle. Be sure to properly
secure any child restraint in your vehicle — even
when no child is in it.

2. SeeSecuring a Child Restraint in the Right
Front Seat Position (Regular and Extended
Cab) (With Airbag Off Switch) on page 78
orSecuring a Child Restraint in the Right
Front Seat Position (Regular and Extended
Cab) (With Passenger Sensing System)
on page 85for instructions on installing the
child restraint using the safety belts.
3. Push and pull the child restraint in different
directions to be sure it is secure.
Extended Cab Models
1. Attach and tighten the lower attachments to
the lower anchors. If the child restraint does
not have lower attachments or the desired
seating position does not have lower anchors,
secure the child restraint with the top tether
and the safety belts. Refer to your child
restraint manufacturer instructions and the
instructions in this manual.
1.1. Find the lower anchors for the desired
seating position.
1.2. Put the child restraint on the seat.
1.3. Attach and tighten the lower
attachments on the child restraint to the
lower anchors.2. If the child restraint manufacturer recommends
that the top tether be attached, attach and
tighten the top tether to the top tether anchor,
if your vehicle has one. Refer to the child
restraint instructions and the following steps:
2.1. When using a child restraint with a top
tether in the rear driver’s side position,
raise the head restraint and route
the top tether through the fabric loop
and under the center shoulder belt.
Then, attach the top tether to the metal
anchor point at the center rear
seating position.
