2008 GMC ENVOY DENALI lock

To assist you in locating
the lower anchors, each
seating position with lower
anchors has two labels,
near the crease between
the seatback and the
seat cushion.
The labels are located above a ap, at the base of
the seatback, in the rear outside seating positions. The
anchors are located under the ap. In order to get to the
anchors you will need to pull the strap at the center of the
seat where the seat cushion meets the seatback. This will
allow you to fold the seat cushion up and out of the way.
Lift the ap to expose the anchors and then lower the
seat cushion. Be sure the cushion is locked into place.The top tether anchors for each rear seating position
are located on the oor in the cargo area of your vehicle.
Do not use the rear tie-down brackets near the liftgate
for attaching top tethers. Be sure to use an anchor
located on the same side of the vehicle as the seating
position where the child restraint will be placed.
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 attached, or if the instructions that
come with the child restraint say that the top tether
must be attached.

{CAUTION:
Children can be seriously injured or strangled
if a shoulder belt is wrapped around their neck
and the safety belt continues to tighten.
Secure any unused safety belts behind the
child restraint so children cannot reach them.
Pull the shoulder belt all the way out of the
retractor to set the lock, if your vehicle has
one, after the child restraint has been installed.
Be sure to follow the instructions of the child
restraint manufacturer.
Notice:Contact between the child restraint LATCH
attachment parts and the vehicle’s safety belt
assembly may cause damage to these parts. Make
sure when securing unused safety belts behind
the child restraint that there is no contact between
the child restraint LATCH attachment parts and
the vehicle’s safety belt assembly.Folding an empty rear seat with the safety belts
secured may cause damage to the safety belt or
the seat. When removing the child restraint, always
remember to return the safety belts to their normal,
stowed position before folding the rear seat.
1. Attach and tighten the lower attachments to the
lower anchors. If the child restraint does not have
lower attachments or the desired seating position
does not have lower anchors, secure the child
restraint with the top tether and the safety belts.
Refer to your child restraint manufacturer
instructions and the instructions in this manual.
1.1. Find the lower anchors for the desired
seating position.
1.2. Pull the strap at the center of the seat where
the seat cushion meets the seatback. This
will allow you to fold the seat cushion up and
out of the way. Lift the ap to expose the
anchors and then lower the seat cushion.
SeeRear Seat Operation on page 1-11
for additional information. Be sure the
cushion is locked into place.
1.3. Put the child restraint on the seat.
1.4. Attach and tighten the lower attachments on
the child restraint to the lower anchors.

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.
7. 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.

The roof-rail airbags for the driver, right front passenger,
and second row outboard passengers are in the
ceiling above the side windows.
{CAUTION:
If something is between an occupant and an
airbag, the airbag 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.
If your vehicle has roof-rail airbags, never
secure anything to the roof of your vehicle by
routing the rope or tie down through any door
or window opening. If you do, the path of an
inating roof-rail airbag will be blocked. Driver Side shown, Passenger Side similar

What Will You See After an Airbag
Inates?
After the frontal airbags inate, they quickly deate,
so quickly that some people may not even realize
an airbag inated. Roof-rail airbags may still be at
least partially inated 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 1-59.
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
deated airbags. Airbag ination 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.
{CAUTION:
When an airbag inates, 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
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 may automatically
unlock the doors, turn the interior lamps on, and turn
the hazard warning ashers on when the airbags inate.
You can lock the doors, turn the interior lamps off,
and turn the hazard warning ashers off by using the
controls for those features.

The passenger sensing system is designed to enable
(may inate) the right front passenger’s frontal
airbag anytime the system senses that a person of adult
size is sitting properly in the right front passenger’s
seat. When the passenger sensing system has allowed
the airbag to be enabled, the on indicator will light
and stay lit to remind you that the airbag is active.
For some children who have outgrown child restraints
and for very small adults, the passenger sensing system
may or may not turn off the right front passenger’s frontal
airbag, depending upon the person’s seating posture
and body build. Everyone in your vehicle who has
outgrown child restraints should wear a safety belt
properly — whether or not there is an airbag for that
person.
If a person of adult-size is sitting in the right front
passenger’s seat, but the off indicator is lit, it could be
because that person is not sitting properly in the seat.
If this happens, turn the vehicle off, remove any additional
material from the seat, such as blankets, cushions, seat
covers, seat heaters or seat massagers and ask the
person to place the seatback in the fully upright position,
then sit upright in the seat, centered on the seat cushion,
with the person’s legs comfortably extended. Restart the
vehicle and have the person remain in this position for
two to three minutes. This will allow the system to detect
that person and then enable the right front passenger’s
frontal airbag.Safety belts help keep the passenger in position on
the seat during vehicle maneuvers and braking, which
helps the passenger sensing system maintain the
passenger airbag status. See “Safety Belts” and “Child
Restraints” in the Index for additional information
about the importance of proper restraint use.
If you ever pull the shoulder portion of the belt out all the
way, you will engage the child restraint locking feature.
This may unintentionally cause the passenger sensing
system to turn the airbag(s) off for some adult size
occupants. If this happens, just let the belt go back
all the way and start again.
