GMC SIERRA DENALI 2010 Owners Manual

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.

Airbag System
The vehicle has the following airbags:
.A frontal airbag for the driver.
.A frontal airbag for the right front passenger.
.A seat‐mounted side impact airbag for the driver.
.A seat‐mounted side impact airbag for the right
front passenger.
.A roof-rail airbag for the driver and passenger
directly behind the driver.
.A roof-rail airbag for the right front passenger and
the person seated directly behind that passenger.
All of the airbags in the vehicle will have the word
AIRBAG embossed in the trim or on an attached label
near the deployment opening.
For frontal airbags, the word AIRBAG will appear on the
middle part of the steering wheel for the driver and on
the instrument panel for the right front passenger.
With seat‐mounted side impact airbags, the word
AIRBAG will appear on the side of the seatback closest
to the door.
With roof-rail airbags, the word AIRBAG will appear
along the headliner or trim. Airbags are designed to supplement the protection
provided by safety belts. Even though today's airbags
are also designed to help reduce the risk of injury from
the force of an inflating bag, all airbags must inflate very
quickly to do their job.
Here are the most important things to know about the
airbag system:
{WARNING:
You can be severely injured or killed in a crash if
you are not wearing your safety belt
—even if you
have airbags. Airbags are designed to work with
safety belts, but do not replace them. Also,
airbags are not designed to deploy in every crash.
In some crashes safety belts are your only
restraint. See When Should an Airbag Inflate?
on
page 2‑61
.
Wearing your safety belt during a crash helps
reduce your chance of hitting things inside the
vehicle or being ejected from it. Airbags are
“supplemental restraints” to the safety belts.
Everyone in your vehicle should wear a safety belt
properly —whether or not there is an airbag for
that person.
2-56

{WARNING:
Airbags inflate with great force, faster than the
blink of an eye. Anyone who is up against, or very
close to, any airbag when it inflates can be
seriously injured or killed. Do not sit unnecessarily
close to the airbag, as you would be if you were
sitting on the edge of your seat or leaning forward.
Safety belts help keep you in position before and
during a crash. Always wear your safety belt,
even with airbags. The driver should sit as far
back as possible while still maintaining control of
the vehicle.
Occupants should not lean on or sleep against the
door or side windows in seating positions with
seat-mounted side impact airbags and/or roof-rail
airbags.
{WARNING:
Children who are up against, or very close to, any
airbag when it inflates 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. Always secure children properly in
your vehicle. To read how, seeOlder Children
on
page 2‑33
or Infants and Young Childrenon
page 2‑36
.
2-57

There is an airbag
readiness light on the
instrument panel cluster,
which shows the airbag
symbol.
The system checks the airbag electrical system for
malfunctions. The light tells you if there is an electrical
problem. See Airbag Readiness Light
on page 4‑31for
more information.
Where Are the Airbags?
The driver frontal airbag is in the middle of the steering
wheel.
2-58

The right front passenger frontal airbag is in the
instrument panel on the passenger's side.
Driver Side Shown, Passenger Side Similar
The seat‐mounted side impact airbags for the driver and
right front passenger are in the side of the seatbacks
closest to the door.
2-59

Driver Side shown, Passenger Side similar
The roof-rail airbags for the driver, right front passenger,
and second row outboard passengers are in the ceiling
above the side windows.
{WARNING:
If something is between an occupant and an
airbag, the airbag might not inflate properly or it
might force the object into that person causing
severe injury or even death. The path of an
inflating airbag must be kept clear. Do not put
anything between an occupant and an airbag, and
do not attach or put anything on the steering
wheel hub or on or near any other airbag
covering.
Do not use seat accessories that block the
inflation path of a seat-mounted side impact
airbag.
Never secure anything to the roof of a vehicle with
roof-rail airbags by routing a rope or tie down
through any door or window opening. If you do,
the path of an inflating roof-rail airbag will be
blocked.
2-60

When Should an Airbag Inflate?
Frontal airbags are designed to inflate in moderate to
severe frontal or near-frontal crashes to help reduce the
potential for severe injuries mainly to the driver's or right
front passenger's head and chest. However, they are
only designed to inflate if the impact exceeds a
predetermined deployment threshold. Deployment
thresholds are used to predict how severe a crash is
likely to be in time for the airbags to inflate and help
restrain the occupants.
Whether the frontal airbags will or should deploy is not
based on how fast your vehicle is traveling. It depends
largely on what you hit, the direction of the impact, and
how quickly your vehicle slows down.
Frontal airbags may inflate at different crash speeds.
For example:
.If the vehicle hits a stationary object, the airbags
could inflate at a different crash speed than if the
vehicle hits a moving object.
.If the vehicle hits an object that deforms, the
airbags could inflate at a different crash speed
than if the vehicle hits an object that does not
deform.
.If the vehicle hits a narrow object (like a pole), the
airbags could inflate at a different crash speed
than if the vehicle hits a wide object (like a wall).
.If the vehicle goes into an object at an angle, the
airbags could inflate at a different crash speed
than if the vehicle goes straight into the object.
Thresholds can also vary with specific vehicle design.
Frontal airbags are not intended to inflate during vehicle
rollovers, rear impacts, or in many side impacts.
If the GVWR (Gross Vehicle Weight Rating) of your
vehicle is 8,500 lb (3 855 kg) or above, the vehicle has
single stage airbags. If the GVWR is below 8,500 lb
(3 855 kg) then the vehicle has dual stage airbags. You
can find the GVWR on the certification label on the rear
edge of the driver's door. See Loading the Vehicle
on
page 5‑31for more information.
The vehicle may have dual‐stage frontal airbags.
Dual-stage airbags adjust the restraint according to
crash severity. The vehicle has electronic frontal
sensors, which help the sensing system distinguish
between a moderate frontal impact and a more severe
frontal impact. For moderate frontal impacts, dual-stage
airbags inflate at a level less than full deployment. For
more severe frontal impacts, full deployment occurs.
2-61

Vehicles with dual stage airbags also have a driver's
seat position sensor which enables the sensing system
to monitor the position of the driver seat (all models).
The seat position sensor provides information that is
used to determine if the airbags should deploy at a
reduced level or at full deployment.
The vehicle may or may not have seat‐mounted side
impact and roof-rail airbags. SeeAirbag System
on
page 2‑56. Seat‐mounted side impact and roof-rail
airbags are intended to inflate in moderate to severe
side crashes. In addition, these roof-rail airbags are
intended to inflate during a rollover or in a severe frontal
impact. Seat‐mounted side impact and roof-rail airbags
will inflate if the crash severity is above the system's
designed threshold level. The threshold level can vary
with specific vehicle design. Roof-rail airbags are not intended to inflate in rear
impacts. A seat‐mounted side impact airbag is intended
to deploy on the side of the vehicle that is struck. Both
roof-rail airbags will deploy when either side of the
vehicle is struck, or if the sensing system predicts that
the vehicle is about to roll over, or in a severe frontal
impact.
In any particular crash, no one can say whether an
airbag should have inflated simply because of the
damage to a vehicle or because of what the repair costs
were. For frontal airbags, inflation is determined by what
the vehicle hits, the angle of the impact, and how
quickly the vehicle slows down. For seat‐mounted side
impact and roof-rail airbags, deployment is determined
by the location and severity of the side impact. In a
rollover event, roof-rail airbag deployment is determined
by the direction of the roll.
2-62

What Makes an Airbag Inflate?
In a deployment event, the sensing system sends an
electrical signal triggering a release of gas from the
inflator. Gas from the inflator fills the airbag causing the
bag to break out of the cover and deploy. The inflator,
the airbag, and related hardware are all part of the
airbag module.
Frontal airbag modules are located inside the
steering wheel and instrument panel. For vehicles with
seat‐mounted side impact airbags, there are airbags
modules in the side of the front seatbacks closest to the
door. For vehicles with roof-rail airbags, there are airbag
modules in the ceiling of the vehicle, near the side
windows that have occupant seating positions.
How Does an Airbag Restrain?
In moderate to severe frontal or near frontal collisions,
even belted occupants can contact the steering wheel
or the instrument panel. In moderate to severe side
collisions, even belted occupants can contact the inside
of the vehicle.
Airbags supplement the protection provided by safety
belts. Frontal airbags distribute the force of the impact
more evenly over the occupant's upper body, stopping
the occupant more gradually. Seat‐mounted side impact
and roof-rail airbags distribute the force of the impact
more evenly over the occupant's upper body.
Rollover capable roof-rail airbags are designed to help
contain the head and chest of occupants in the
outboard seating positions in the first and second rows.
The rollover capable roof-rail airbags are designed to
help reduce the risk of full or partial ejection in rollover
events, although no system can prevent all such
ejections.
But airbags would not help in many types of collisions,
primarily because the occupant's motion is not toward
those airbags. SeeWhen Should an Airbag Inflate?
on
page 2‑61for more information.
Airbags should never be regarded as anything more
than a supplement to safety belts.
2-63

What Will You See After an Airbag
Inflates?
After the frontal airbags and seat-mounted side impact
airbags inflate, they quickly deflate, so quickly that
some people may not even realize an airbag inflated.
Roof-rail airbags may still be at least partially inflated for
some time after they deploy. Some components of the
airbag module may be hot for several minutes. For
location of the airbag modules, seeWhat Makes an
Airbag Inflate? on page 2‑63.
The parts of the airbag that come into contact with you
may be warm, but not too hot to touch. There may be
some smoke and dust coming from the vents in the
deflated airbags. Airbag inflation does not prevent the
driver from seeing out of the windshield or being able to
steer the vehicle, nor does it prevent people from
leaving the vehicle.
{WARNING:
When an airbag inflates, there may be dust in the
air. This dust could cause breathing problems for
people with a history of asthma or other breathing
trouble. To avoid this, everyone in the vehicle
should get out as soon as it is safe to do so.
If you have breathing problems but cannot get out
of the vehicle after an airbag inflates, then get
fresh air by opening a window or a door. If you
experience breathing problems following an airbag
deployment, you should seek medical attention.
The vehicle has a feature that may automatically unlock
the doors, turn on the interior lamps and hazard warning
flashers, and shut off the fuel system after the airbags
inflate. You can lock the doors, turn off the interior
lamps and hazard warning flashers by using the
controls for those features.
