2007 GMC SIERRA seats

Safety Belt Pretensioners
Your vehicle has safety belt pretensioners for the
driver and right front passenger. Although you
cannot see them, they are part of the safety belt
assembly. They help tighten the safety belts during
the early stages of a moderate to severe frontal,
near frontal, or rear crash if the threshold conditions
for pretensioner activation are met. And, if your
vehicle has side impact rollover airbags, safety belt
pretensioners can help tighten the safety belts in a
side crash or a rollover event.
Pretensioners work only once. If they activate in a
crash, you will need to get new ones, and
probably other new parts for your safety belt
system. SeeReplacing Restraint System Parts
After a Crash on page 105.
Safety Belt Extender
If the vehicle’s safety belt will fasten around you,
you should use it.
But if a safety belt is not long enough, your
dealer/retailer will order you an extender. When
you go in to order it, take the heaviest coat you will
wear, so the extender will be long enough for
you. To help avoid personal injury, do not
let someone else use it, and use it only for the
seat it is made to t. The extender has been
designed for adults. Never use it for securing child
seats. To wear it, attach it to the regular safety
belt. For more information, see the instruction
sheet that comes with the extender.

Child Restraints
Older Children
Older children who have outgrown booster seats
should wear the vehicle’s safety belts.
Q:What is the proper way to wear safety
belts?
A: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.
According to accident statistics, children are safer
when properly restrained in the rear seating
positions than in the front seating positions.
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.
45

A booster seat (F-G) is a child restraint designed
to improve the t of the vehicle’s safety belt
system. Some booster seats have a shoulder belt
positioner, and some high-back booster seats
have a ve-point harness. A booster seat can also
help a child to see out the window.
Q:How Should I Use a Child Restraint?
A:A child restraint system is any device designed
for use in a motor vehicle to restrain, seat, or
position children. A built-in child restraint
system is a permanent part of the motor
vehicle. An add-on child restraint system is a
portable one, which is purchased by the
vehicle’s owner. To help reduce injuries, an
add-on child restraint must be secured in
the vehicle. With built-in or add-on child
restraints, the child has to be secured within
the child restraint.
When choosing an add-on child restraint, be
sure the child restraint is designed to be
used in a vehicle. If it is, it will have a label
saying that it meets federal motor vehicle
safety standards. Then follow the instructions
for the restraint. You may nd these
instructions on the restraint itself or in a
booklet, or both.

Securing an Add-on Child Restraint in
the Vehicle
{CAUTION:
A child can be seriously injured or killed
in a crash if the child restraint is not
properly secured in the vehicle. Make sure
the child restraint is properly installed in
the vehicle using the vehicle’s safety belt
or LATCH system, following the
instructions that came with that restraint,
and also the instructions in this manual.To help reduce the chance of injury, the child
restraint must be secured in the vehicle. Child
restraint systems must be secured in vehicle seats
by lap belts or the lap belt portion of a lap-shoulder
belt, or by the LATCH system. SeeLower
Anchors and Tethers for Children (LATCH) on
page 58for more information. A child can
be endangered in a crash if the child restraint is
not properly secured in the vehicle.
When securing an add-on child restraint, refer to
the instructions that come with the restraint
which may be on the restraint itself or in a booklet,
or both, and to this manual. The child restraint
instructions are important, so if they are not
available, obtain a replacement copy from the
manufacturer.
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.
54

Do not secure a child restraint in the front
passenger’s position if your vehicle has rear seats,
if a national or local law requires that the top
tether be attached, or if the instructions that come
with the child restraint say that the top tether
must be attached. There is no place to attach the
top tether in this position.
Accident statistics show that children are safer if
they are restrained in the rear rather than the front
seat. SeeWhere to Put the Restraint on page 56
for additional information.
Securing a Child Restraint Designed for
the LATCH System
{CAUTION:
If a LATCH-type child restraint is not
attached to anchors, the restraint will not
be able to protect the child correctly. In a
crash, the child could be seriously injured
or killed. Make sure that a LATCH-type
CAUTION: (Continued)
CAUTION: (Continued)
child restraint is properly installed using
the anchors, or use the vehicle’s safety
belts to secure the restraint, following the
instructions that came with that restraint,
and also the instructions in this manual.
{CAUTION:
Each top tether anchor, except the center
top tether anchors in crew and extended
cab models, and lower anchors in the
vehicle are designed to hold only one
child restraint. Attaching more than one
child restraint to a single anchor could
cause the anchor or attachment to come
loose or even break during a crash.
CAUTION: (Continued)
62

A rear seat is a safer place to secure a forward
facing child restraint. SeeWhere to Put the
Restraint on page 56. If you need to secure a
forward-facing child restraint in the right front seat
position, move the seat as far back as it will go
before securing a forward-facing child restraint.
SeeManual Seats on page 9orPower Seats on
page 10.
{CAUTION:
If the airbag readiness light in the
instrument panel cluster ever comes on
when you have turned off the airbag, it
means that something may be wrong with
the airbag system. The right front
passenger’s airbag could inate even
though the switch is off. If this ever
happens, have the vehicle serviced
promptly. Until you have the vehicle
CAUTION: (Continued)
CAUTION: (Continued)
serviced, do not let anyone whom the
national government has identied as a
member of a passenger airbag risk group
sit in the right front passenger’s position
(for example, do not secure a rear-facing
child restraint in the right front
passenger’s seat). SeeAirbag Off Switch
on page 93.
If your child restraint has the LATCH system, see
Lower Anchors and Tethers for Children
(LATCH) on page 58.
If your vehicle has a rear seat, there is no top
tether anchor at the right front seating position. Do
not secure a child seat in this position if a
national or local law requires that the top tether be
anchored or if the instructions that come with
the child restraint say that the top tether must be
anchored. SeeLower Anchors and Tethers for
Children (LATCH) on page 58if the child restraint
has a top tether.

You will be using the lap-shoulder belt to secure
the child restraint in this position. Be sure to follow
the instructions that came with the child restraint.
Secure the child in the child restraint when and as
the instructions say.
1. Your vehicle has a right front passenger’s
frontal airbag. SeeAirbag Off Switch on
page 93. If your child restraint is
forward-facing, move the seat as far back as
it will go before securing the restraint in
this seat. SeeManual Seats on page 9or
Power Seats on page 10. If you need to use a
rear-facing child restraint in this seat, make
sure the airbag is off once the child restraint
has been installed.
When the airbag off switch has turned off the
right front passenger’s frontal airbag, the
off indicator in the overhead console should
light and stay lit when you turn the ignition to
RUN or START after the system check is
completed. SeeAirbag Off Light on page 250.
2. Put the child restraint on the seat.3. Pick up the latch plate, and run the lap and
shoulder portions of the vehicle’s safety belt
through or around the restraint. The child
restraint instructions will show you how.
4. Buckle the belt. Make sure the release button
is positioned so you would be able to unbuckle
the safety belt quickly if you ever had to.
73

CAUTION: (Continued)
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.
If your vehicle does not have a rear seat that will
accommodate a rear-facing child restraint, we
recommend that rear-facing child restraints not be
transported in your vehicle, even if the airbag is off.
If your child restraint has the LATCH system, see
Lower Anchors and Tethers for Children
(LATCH) on page 58.
If your vehicle has a rear seat, there is no top
tether anchor at the right front seating position. Do
not secure a child seat in this position if a
national or local law requires that the top tether be
anchored or if the instructions that come with
the child restraint say that the top tether must be
anchored. SeeLower Anchors and Tethers for
Children (LATCH) on page 58if the child restraint
has a top tether.You will be using the lap-shoulder belt to secure
the child restraint in this position. Be sure to follow
the instructions that came with the child restraint.
Secure the child in the child restraint when and as
the instructions say.
1. Your vehicle has a right front passenger’s
frontal airbag. SeePassenger Sensing
System on page 97. We recommend that
rear-facing child restraints be secured in a rear
seat, even if the airbag is off. If your child
restraint is forward-facing, move the seat as
far back as it will go before securing the
child restraint in this seat. SeeManual Seats
on page 9orPower Seats on page 10.
When the passenger sensing system has
turned off the right front passenger’s frontal
airbag, the off indicator in the passenger
airbag status indicator should light and stay lit
when you turn the ignition to RUN or
START after the system check is completed.
SeePassenger Airbag Status Indicator on
page 252.
2. Put the child restraint on the seat.
