2010 GMC SIERRA DENALI airbag

Shoulder Belt Height Adjuster
The vehicle has a shoulder belt height adjuster for the
driver and right front passenger positions.
Adjust the height so that the shoulder portion of the belt
is centered on the shoulder. The belt should be away
from the face and neck, but not falling off the shoulder.
Improper shoulder belt height adjustment could reduce
the effectiveness of the safety belt in a crash.
Squeeze the buttons (A)
on the sides of the height
adjuster and move the
height adjuster to the
desired position.
The adjuster can be moved up just by pushing up on
the shoulder belt guide.
After the adjuster is set to the desired position, try to
move it down without squeezing the buttons to make
sure it has locked into position.
Safety Belt Pretensioners
This vehicle has safety belt pretensioners for front
outboard occupants. Although the safety belt
pretensioners cannot be seen, they are part of the
safety belt assembly. They can 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 the vehicle has side impact airbags, safety belt
pretensioners can help tighten the safety belts in a side
crash or a rollover event.
Pretensioners work only once. If the pretensioners
activate in a crash, they will need to be replaced, and
probably other new parts for the vehicle's safety belt
system. See Replacing Restraint System Parts After a
Crash on page 2‑74.

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.
{WARNING:
Children can be seriously injured or strangled if a
shoulder belt is wrapped around their neck and
the safety belt continues to tighten. Never leave
children unattended in a vehicle and never allow
children to play with the safety belts.
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. Every time infants
and young children ride in vehicles, they should have
the protection provided by appropriate child restraints.
Children who are not restrained properly can strike
other people, or can be thrown out of the vehicle.
{WARNING:
Never do this.
Never hold an infant or a child while riding in a
vehicle. Due to crash forces, an infant or a child
will become so heavy it is not possible to hold it
during a crash. For example, in a crash at only
40 km/h (25 mph), a 5.5 kg (12 lb) infant will
suddenly become a 110 kg (240 lb) force on a
person's arms. An infant should be secured in an
appropriate restraint.

{WARNING:
Never do this.
Children who are up against, or very close to, any
airbag when it inflates can be seriously injured or
killed. Never put a rear-facing child restraint in the
right front seat. Secure a rear-facing child restraint
in a rear seat. It is also better to secure a(Continued)
WARNING: (Continued)
forward-facing child restraint in a rear seat. If you
must secure a forward-facing child restraint in the
right front seat, always move the front passenger
seat as far back as it will go.
2-37

Where to Put the Restraint
According to accident statistics, children and infants are
safer when properly restrained in a child restraint
system or infant restraint system secured in a rear
seating position.
We recommend that children and child restraints be
secured in a rear seat, including: an infant or a child
riding in a rear-facing child restraint; a child riding in a
forward-facing child seat; an older child riding in a
booster seat; and children, who are large enough, using
safety belts.
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.
{WARNING:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger airbag inflates. This is because the
back of the rear-facing child restraint would be
very close to the inflating airbag. A child in a
forward-facing child restraint can be seriously
(Continued)
WARNING: (Continued)
injured or killed if the right front passenger airbag
inflates and the passenger seat is in a forward
position.
The vehicle may have a passenger sensing
system which is designed to turn off the right front
passenger frontal airbag under certain conditions.
Even if the passenger sensing system,
if equipped, has turned off the right front
passenger frontal airbag, no system is fail-safe.
No one can guarantee that an airbag will not
deploy under some unusual circumstance, even
though it is turned off.
Secure rear-facing child restraints 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 2‑66
for additional information.

{WARNING:
A child in a child restraint in the center front seat
can be badly injured or killed by the frontal
airbags if they inflate. 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.
When securing a child restraint in a rear seating
position, study the instructions that came with your child
restraint to make sure it is compatible with this vehicle.
Wherever a child restraint is installed, 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.
Lower Anchors and Tethers for
Children (LATCH)
The LATCH system holds a child restraint during driving
or in a crash. This system is designed to make
installation of a child restraint easier. The LATCH
system uses anchors in the vehicle and attachments on
the child restraint that are made for use with the LATCH
system.
Make sure that a LATCH-compatible 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. When installing a child
restraint with a top tether, you must also use either the
lower anchors or the safety belts to properly secure the
child restraint. A child restraint must never be installed
using only the top tether and anchor.
In order to use the LATCH system in your vehicle, you
need a child restraint that has LATCH attachments. The
child restraint manufacturer will provide you with
instructions on how to use the child restraint and its
attachments. The following explains how to attach a
child restraint with these attachments in your vehicle.
Not all vehicle seating positions or child restraints have
lower anchors and attachments or top tether anchors
and attachments.
2-43

To remove the child restraint, unbuckle the vehicle
safety belt and let it return to the stowed position. If the
top tether is attached to a top tether anchor,
disconnect it.
Securing a Child Restraint in the
Right Front Seat Position
This vehicle has airbags. A rear seat is a safer place to
secure a forward-facing child restraint. SeeWhere to
Put the Restraint on page 2‑42.
In addition, the vehicle may have a passenger sensing
system which is designed to turn off the right front
passenger frontal airbag under certain conditions. See
Passenger Sensing System
on page 2‑66and
Passenger Airbag Status Indicatoron page 4‑32for
more information, including important safety information.
A label on the 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.
{WARNING:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger airbag inflates. This is because the
back of the rear-facing child restraint would be
very close to the inflating airbag. A child in a
forward-facing child restraint can be seriously
injured or killed if the right front passenger airbag
inflates and the passenger seat is in a forward
position.
The vehicle may have a passenger sensing
system which is designed to turn off the right front
passenger frontal airbag under certain conditions.

WARNING: (Continued)
Even if the passenger sensing system,
if equipped, has turned off the right front
passenger frontal airbag, no system is fail-safe.
No one can guarantee that an airbag will not
deploy under some unusual circumstance, even
though it is turned off.
Secure rear-facing child restraints 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 2‑66
for additional information.
If the child restraint has the LATCH system, see Lower
Anchors and Tethers for Children (LATCH)
on
page 2‑43for how and where to install the child
restraint using LATCH. If a child restraint is secured
using a safety belt and it uses a top tether, see Lower
Anchors and Tethers for Children (LATCH)
on
page 2‑43for 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.
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.
2-53

6. To tighten the belt, push down on the childrestraint, pull the shoulder portion of the belt to
tighten the lap portion of the belt and feed the
shoulder belt back into the retractor. When
installing a forward-facing child restraint, it may be
helpful to use your knee to push down on the child
restraint as you tighten the belt.
7. Push and pull the child restraint in different directions to be sure it is secure. If the vehicle is equipped with the passenger sensing
system, and when the passenger sensing system has
turned off the right front passenger frontal airbag, the off
indicator in the passenger airbag status indicator should
light and stay lit when you start the vehicle. See
Passenger Airbag Status Indicator on page 4‑32.
If a child restraint has been installed and the on
indicator is lit, see
“If the On Indicator is Lit for a Child
Restraint” underPassenger Sensing System
on
page 2‑66for more information.
To remove the child restraint, unbuckle the vehicle
safety belt and let it return to the stowed position.
