GMC ENVOY DENALI 2005 Workshop Manual

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.5. Pull the rest of the shoulder belt all the way out of
the retractor to set the lock.

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. You should not be
able to pull more of the belt from the retractor
once the lock has been set.
1-46

7. Push and pull the child restraint in different
directions to be sure it is secure.
8. If the airbag is off, the off indicator in the inside
rearview mirror will be lit and stay lit when the
key is turned to RUN or START.
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, slightlyrecline 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.
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.
To remove the child restraint, just unbuckle the vehicle’s
safety belt and let it go back all the way. The safety
belt will move freely again and be ready to work for an
adult or larger child passenger.

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

CAUTION: (Continued)
Frontal airbags for the driver and right front
passenger are designed to deploy only in
moderate to severe frontal and near frontal
crashes. They are not designed to inate in
rollover, rear or low-speed frontal crashes, or in
many side crashes. And, for some unrestrained
occupants, frontal airbags may provide less
protection in frontal crashes than more forceful
airbags have provided in the past.
The roof-mounted airbags are designed to
inate only in moderate to severe crashes
where something hits the side of your vehicle.
They are not designed to inate in frontal or in
rear crashes. If the vehicle is equipped with
rollover capable airbags, it has been designed
to deploy the roof-mounted airbags in the event
of a vehicle rollover. Everyone in your vehicle
should wear a safety belt properly — whether or
not there is an airbag for that person.
{CAUTION:
Both frontal and roof—mounted airbags inate
with great force, faster than the blink of an
eye. If you are too close to an inating airbag,
as you would be if you were leaning forward, it
could seriously injure you. Safety belts help
keep you in position for airbag ination before
and during a crash. Always wear your safety
belt even with frontal 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.

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. SeeAirbag Readiness Light on page 3-36
for more information.Where Are the Airbags?
The driver’s airbag is in the middle of the steering wheel.
1-50

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

When Should an Airbag Inate?
The driver’s and right front passenger’s frontal airbags
are designed to inate in moderate to severe frontal or
near-frontal crashes. But they are designed to inate only
if the impact exceeds a predetermined deployment
threshold. Deployment thresholds take into account a
variety of desired deployment and non-deployment
events and are used to predict how severe a crash is
likely to be in time for the airbags to inate and help
restrain the occupants. Whether your 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.
In addition, your vehicle has “dual stage” frontal airbags,
which adjust the restraint according to crash severity.
Your vehicle is equipped with electronic frontal sensors,
which help the sensing system distinguish between a
moderate frontal impact and a more severe frontal
impact. For moderate frontal impacts, these airbags
inate at a level less than full deployment. For more
severe frontal impacts, full deployment occurs. If the front
of your vehicle goes straight into a wall that does not
move or deform, the threshold level for the reduced
deployment is about 9 to 16 mph (14 to 26 km/h), and the
threshold level for a full deployment is about 18 to 25 mph
(29 to 40 km/h). (The threshold level can vary, however,
with specic vehicle design, so that it can be somewhat
above or below this range.)Airbags may inate at different crash speeds.
For example:If the vehicle hits a stationary object, the airbag
could inate at a different crash speed than if
the object were moving.
If the object deforms, the airbag could inate at a
different crash speed than if the object does not
deform.
If the vehicle hits a narrow object (like a pole) the
airbag could inate 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
airbag could inate at a different crash speed
than if the vehicle goes straight into the object.
The frontal airbags (driver and right front passenger)
are not intended to inate during vehicle rollovers, rear
impacts, or in many side impacts because ination
would not likely help the occupants.
1-53

Your vehicle may or may not have a roof-mounted
airbag and rollover sensor. SeeAirbag System
on page 1-48. These “rollover capable” airbags are
designed to inate in moderate to severe side crashes
or during a rollover. A side impact airbag will inate
if the crash severity is above the system’s designed
“threshold level.” The threshold level can vary with
specic vehicle design. Side impact airbags are not
designed to inate in frontal or near-frontal impacts, or
rear impacts, because ination would not likely help
the occupant.
Your vehicle has seat position sensors which enable the
sensing system to monitor the position of the driver’s
seat and the right front passenger’s seat. Seat position
sensors provide information that is used to determine
if the airbags should deploy at a reduced level or at full
deployment.In any particular crash, no one can say whether an
airbag should have inated simply because of the
damage to a vehicle or because of what the repair costs
were. For frontal airbags, ination is determined by
the angle of the impact and how quickly the vehicle
slows down in frontal and near-frontal impacts. For side
impact airbags, ination is determined by the location
and severity of the impact.
The airbag system is designed to work properly under a
wide range of conditions, including off-road usage.
Observe safe driving speeds, especially on rough
terrain. As always, wear your safety belt. SeeOff-Road
Driving with Your Four-Wheel-Drive Vehicle on
page 4-16for tips on off-road driving.
