GMC SIERRA 2008 Repair Manual

6. If your child restraint has a top tether, follow the
child restraint manufacturer’s instructions regarding
the use of the top tether. SeeLower Anchors
and Tethers for Children (LATCH) on page 1-45for
more information.
7. Push and pull the child restraint in different
directions to be sure it is secure.
To remove the child restraint, unbuckle the vehicle’s
safety belt and let it go back all the way. If the top tether
is attached to a top tether anchor, disconnect it.Securing a Child Restraint in the
Center Front Seat Position
{CAUTION:
A child in a child restraint in the center front
seat can be badly injured or killed by the
frontal airbags if they inate. Never secure a
child restraint in the center front seat. It is
always better to secure a child restraint in a
rear seat.
Do not use child restraints in the center front seat
position.

Securing a Child Restraint in the
Right Front Seat Position (With
Airbag Off Switch)
Your vehicle has airbags. A rear seat is a safer place to
secure a forward-facing child restraint. SeeWhere to
Put the Restraint on page 1-44.
There may be a switch in the glove box that you can
use to turn off the right front passenger’s frontal airbag.
SeeAirbag Off Switch on page 1-76for more on
this, including important safety information.
A label on your sun visor 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.
{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.
Even though the airbag off switch is designed
to turn off the right front passenger’s frontal
airbag, 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. We recommend that rear-facing
child restraints be secured in the rear seat,
even if the airbag is off.
If you 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.
1-58

{CAUTION:
If the airbag readiness light 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, 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)
until you have your vehicle serviced. See
Airbag Off Switch on page 1-76andAirbag
Readiness Light on page 3-38for more on this,
including important safety information.
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, seeLower
Anchors and Tethers for Children (LATCH) on
page 1-45for how to install your child restraint usingLATCH. If you secure a child restraint using a safety
belt and it uses a top tether, seeLower Anchors
and Tethers for Children (LATCH) on page 1-45for top
tether anchor locations.
Do not secure a child restraint in a position without a
top tether anchor 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 strap must
be anchored.
In Canada, the law requires that forward-facing child
restraints have a top tether, and that the tether be
attached.
You will be using the lap-shoulder belt to secure the
child restraint in this position. Follow the instructions that
came with the child restraint.
1. Move the seat as far back as it will go before
securing the forward-facing child restraint.
If you have no other choice but to install 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 airbag off light should light and stay lit when
you start the vehicle. SeeAirbag Off Light on
page 3-39.
2. Put the child restraint on the seat.
1-59

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. Push the latch plate into the buckle until it clicks.
Make sure the release button is positioned so you
would be able to unbuckle the safety belt quickly
if necessary.5. Pull the rest of the shoulder belt all the way out of
the retractor to set the lock.
1-60

6. To tighten the belt, push down on the child restraint,
pull the shoulder portion of the belt to tighten the
lap portion of the belt and feed the shoulder
belt back into the retractor. If you are using a
forward-facing child restraint, you may nd it helpful
to use your knee to push down on the child
restraint as you tighten the belt.
7. If your vehicle does not have a rear seat and your
child restraint has a top tether, follow the child
restraint manufacturer’s instructions regarding the
use of the top tether. SeeLower Anchors and
Tethers for Children (LATCH) on page 1-45.8. Push and pull the child restraint in different
directions to be sure it is secure.
To remove the child restraint, unbuckle the vehicle’s
safety belt and let it go back all the way. If the top tether
is attached to a top tether anchor, disconnect it.
If you had turned the airbag off with the switch,
remember to be sure to use the airbag off switch to turn
on the right front passenger’s airbag when you remove
the child restraint from the vehicle unless the person
who will be sitting there is a member of a passenger
airbag risk group. SeeAirbag Off Switch on page 1-76.
{CAUTION:
If the right front passenger’s airbag is turned
off for a person who is not in a risk group
identied by the national government, that
person will not have the extra protection of an
airbag. In a crash, the airbag will not be able to
inate and help protect the person sitting there.
Do not turn off the passenger’s airbag unless
the person sitting there is in a risk group
identied by the national government. See
Airbag Off Switch on page 1-76for more on this,
including important safety information.

Securing a Child Restraint in the
Right Front Seat Position (With
Passenger Sensing System)
Your vehicle has airbags. A rear seat is a safer place to
secure a forward-facing child restraint. SeeWhere to
Put the Restraint on page 1-44.
In addition, your vehicle may have a passenger sensing
system which is designed to turn off the right front
passenger’s frontal airbag under certain conditions. See
Passenger Sensing System on page 1-80and
Passenger Airbag Status Indicator on page 3-41for
more information on this, including important safety
information.
A label on your sun visor 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.
{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.
Even though the passenger sensing system is
designed to turn off the right front passenger’s
frontal airbag if the system detects a
rear-facing child restraint, 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. We
recommend that rear-facing child restraints be
secured in a rear seat, even if the airbag is off.
If you 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.
SeePassenger Sensing System on page 1-80
for additional information.

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, seeLower
Anchors and Tethers for Children (LATCH) on
page 1-45for how to install your child restraint using
LATCH. If you secure a child restraint using a safety belt
and it uses a top tether, seeLower Anchors and
Tethers for Children (LATCH) on page 1-45for top
tether anchor locations.
Do not secure a child seat in a position without a top
tether anchor 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 strap must
be anchored.
In Canada, the law requires that forward-facing child
restraints have a top tether, and that the tether be
attached.
You will be using the lap-shoulder belt to secure the
child restraint in this position. Follow the instructions that
came with the child restraint.
1. Move the seat as far back as it will go before
securing the forward-facing child restraint.

7. If your child restraint manufacturer recommends
using a top tether and the position you are using
has a top tether anchor, attach and tighten the top
tether to the top tether anchor. Refer to the
instructions that came with the child restraint and to
Lower Anchors and Tethers for Children (LATCH)
on page 1-45.
8. Push and pull the child restraint in different
directions to be sure it is secure.
If the airbag is off, the off indicator in the passenger
airbag status indicator will come on and stay on when
the vehicle is started.
If a child restraint has been installed and the on
indicator is lit, turn the vehicle off. Remove the child
restraint from the vehicle and reinstall the child restraint.If, after reinstalling the child restraint and restarting the
vehicle, the on indicator is still lit, check to make
sure that the vehicle’s seatback is not pressing the child
restraint into the seat cushion. If this happens, slightly
recline the vehicle’s seatback and adjust the seat
cushion if possible. Also make sure the child restraint is
not trapped under the vehicle head restraint. If this
happens, adjust the head restraint.
Remove any additional material from the seat such as
blankets, cushions, seat covers, seat heaters or seat
massagers before reinstalling or securing the child
restraint.
If the on indicator is still lit, secure the child in the child
restraint in a rear seat position in the vehicle and
check with your dealer/retailer. If no rear seat is
available, do not install a child restraint in this vehicle
and check with your dealer/retailer.
To remove the child restraint, unbuckle the vehicle’s
safety belt and let it go back all the way. If the top tether
is attached to a top tether anchor, disconnect it.
