2005 GMC Envoy/Envoy XL/Envoy Denali Owner ManualM

Q:What if a child is wearing a lap-shoulder belt,
but the child is so small that the shoulder belt
is very close to the child’s face or neck?
A:If the child is sitting in a seat next to a window,
move the child toward the center of the vehicle.
If the child is sitting in the center rear seat
passenger position, move the child toward the
safety belt buckle. In either case, be sure that the
shoulder belt still is on the child’s shoulder, so
that in a crash the child’s upper body would have
the restraint the belts provide.
If the child is sitting in a rear seat outside position,
seeRear Safety Belt Comfort Guides for Children
and Small Adults on page 1-23.
{CAUTION:
Never do this.
Here a child is sitting in a seat that has a
lap-shoulder belt, but the shoulder part is
behind the child. If the child wears the belt in
this way, in a crash the child might slide under
the belt. The belt’s force would then be applied
right on the child’s abdomen. That could cause
serious or fatal injuries.
1-28

A forward-facing child seat (C-E) provides restraint for
the child’s body with the harness and also sometimes
with surfaces such as T-shaped or shelf-like shields.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.

Airbag System
Your vehicle has a frontal airbag for the driver and
another frontal airbag for the right front passenger. Your
vehicle may also have roof-mounted airbags designed for
either side impact or rollover deployment. Roof-mounted
airbags are available for the driver and the passenger
seated directly behind the driver and for the right front
passenger and the passenger seated directly behind that
passenger.
If your vehicle has roof-mounted airbags, the words AIR
BAG will appear on the airbag covering on the sidewall
trim near the driver’s and right front passenger’s window.
Frontal airbags are designed to help reduce the risk of
injury from the force of an inating frontal airbag.
But these airbags must inate very quickly to do their
job and comply with federal regulations.Here are the most important things to know about the
airbag system:
{CAUTION:
You can be severely injured or killed in a crash
if you are not wearing your safety belt — even
if you have airbags. 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. All airbags are
designed to work with safety belts but do not
replace them.
CAUTION: (Continued)
1-48

The right front passenger’s airbag is in the instrument
panel on the passenger’s side.If your vehicle has a roof-mounted airbag for the driver
and the person seated directly behind the driver, it
is located in the ceiling above the side windows.
1-51

If your vehicle has a roof-mounted airbag for the right
front passenger and the person directly behind that
passenger, it is located in the ceiling above the
side windows.
{CAUTION:
If something is between an occupant and an
airbag, the bag might not inate properly or it
might force the object into that person causing
severe injury or even death. The path of an
inating 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. And, if your vehicle has
roof-mounted airbags, never secure anything
to the roof of your vehicle by routing the rope
or tiedown through any door or window
opening. If you do, the path of an inating side
impact airbag will be blocked. The path of an
inating airbag must be kept clear.
1-52

What Makes an Airbag Inate?
In an impact of sufficient severity, the airbag sensing
system detects that the vehicle is in a crash. In the case
of a “rollover capable” roof-mounted airbag, the
sensing system detects that the vehicle is about to roll
over. For both frontal and roof-mounted airbags, the
sensing system triggers a release of gas from the
inator, which inates the airbag. The inator, airbag,
and related hardware are all part of the airbag modules
inside the steering wheel and in the instrument panel
in front of the right front passenger. For vehicles
with roof-mounted airbags, the airbag modules are
located in the ceiling of the vehicle, near the side
windows.
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. The airbag supplements the protection
provided by safety belts. Airbags distribute the force of
the impact more evenly over the occupant’s upper
body, stopping the occupant more gradually. But the
frontal airbags would not help you in many types
of collisions, including rollovers, rear impacts, and many
side impacts, primarily because an occupant’s motion
is not toward the airbag. Roof-mounted airbags
would not help you in many types of collisions, including
frontal or near frontal collisions, and rear impacts,
primarily because an occupant’s motion is not toward
those airbags. Airbags should never be regarded
as anything more than a supplement to safety belts, and
then only in moderate to severe frontal or near-frontal
collisions for the driver’s and right front passenger’s
frontal airbags, and only in moderate to severe
side collisions or rollovers for the roof-mounted airbags.
1-55

What Will You See After an Airbag
Inates?
After an airbag inates, it quickly deates, so quickly
that some people may not even realize the airbag
inated. Some components of the airbag module — the
steering wheel hub for the driver’s airbag, the
instrument panel for the right front passenger’s bag or
the ceiling of your vehicle near the side windows — will
be hot for a short time. The parts of the bag that
come into contact with you may be warm, but not too
hot to touch. There will be some smoke and dust coming
from the vents in the deated airbags. Airbag ination
does not prevent the driver from seeing or being able to
steer the vehicle, nor does it stop people from leaving
the vehicle.
{CAUTION:
When an airbag inates, there is 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
can not get out of the vehicle after an airbag
inates, 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.
Your vehicle has a feature that will automatically unlock
the doors and turn the interior lamps on when the
airbags inate (if battery power is available). You can
lock the doors again and turn the interior lamps off
by using the door lock and interior lamp controls.
