GMC SIERRA 2007 Manual Online

If your child restraint has the LATCH system, see
Lower Anchors and Tethers for Children
(LATCH) on page 58.
There is no top tether anchor in the right front
passenger’s position. Do not secure a child seat in
this position 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 tether must be anchored. See
Lower Anchors and Tethers for Children (LATCH)
on page 58if your child restraint has a top
tether.
You will be using the lap-shoulder belt to secure
the restraint in this position. Be sure to follow
the instructions that came with the child restraint.
Secure the child in the child restraint when
and as the instructions say.
1. Because your vehicle has a right front
passenger’s frontal airbag, always move
the seat as far back as it will go before
securing a forward-facing child restraint. See
Manual Seats on page 9orPower Seats
on page 10.
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.
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.
81

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 out of the retractor
once the lock has been set.
82

7. Push and pull the child restraint in different
directions to be sure it is secure.
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 the following airbags:
A frontal airbag for the driver.
A frontal airbag for the right front passenger.Your vehicle may have the following airbags:
A roof-mounted rollover airbag for the driver
and right front passenger.
A roof-mounted rollover airbag for the second
row outboard passenger positions.
If your vehicle has roof-mounted rollover airbags,
the word AIRBAG will appear on the airbag
covering on the headliner above the sidewall trim
near the driver’s and right front passenger’s
window and the rear passenger’s outboard seating
positions.
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 inating bag, all
airbags must inate very quickly to do their job.
83

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:
Frontal airbags for the driver and right
front passenger are designed to deploy in
moderate to severe frontal and near
frontal crashes. They are not designed to
inate in rollover, rear 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.
Roof-mounted rollover airbags are
designed to inate in moderate to severe
crashes where something hits the side of
your vehicle, during a vehicle rollover, or
in a severe frontal impact. They are not
designed to inate in rear crashes. If your
vehicle has roof-mounted airbags, they
are designed to provide both side impact
protection and rollover protection.
CAUTION: (Continued)
84

CAUTION: (Continued)
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 side impact
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.
{CAUTION:
Anyone who is up against, or very close
to, any airbag when it inates can be
seriously injured or killed. Airbags plus
lap-shoulder belts offer the best
protection for adults, 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 45orInfants and Young Children on
page 48.
85

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 250for more information.Where Are the Airbags?
The driver’s airbag is in the middle of the steering
wheel.
86

The right front passenger’s airbag is in the
instrument panel on the passenger’s side.If your vehicle has a roof-mounted rollover airbag
for the driver and the person seated directly
behind the driver, it is located in the ceiling above
the side windows.
87

If your vehicle has a roof-mounted rollover 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 side impact 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 side
impact airbag will be blocked. The path of
an inating airbag must be kept clear.
88

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.
Frontal airbags may inate at different crash
speeds. For example:
If the vehicle hits a stationary object, the
airbags could inate at a different crash speed
than if the vehicle hits a moving object.
If the vehicle hits an object that deforms, the
airbags could inate 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 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 airbags could inate at a different crash
speed than if the vehicle goes straight into
the object.
Frontal airbags (driver and right front passenger)
are not intended to inate during vehicle
rollovers, rear impacts, or in many side impacts.
Your vehicle has a seat position sensor which
enables the sensing system to monitor the
fore and aft position of the driver’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.
Your vehicle may or may not have roof-mounted
rollover airbags and a rollover sensor. See
Airbag System on page 83. These “rollover
capable” airbags are intended to inate in
moderate to severe side crashes, during a rollover,
or in a severe frontal impact. A roof-mounted
rollover airbag will inate if the crash severity is
above the system’s designed “threshold level.”
89

The threshold level can vary with specic vehicle
design. Roof-mounted airbags are not intended
to inate in rear impacts. Both roof-mounted
rollover airbags will deploy when either side of the
vehicle is struck, during a rollover, or in a
severe frontal impact.
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 what the vehicle hits, the angle
of the impact, and how quickly the vehicle slows
down. For roof-mounted rollover airbags,
ination is determined by the location and severity
of the impact or a rollover event.
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 on page 390for tips on
off-road driving.
If the GVWR (Gross Vehicle Weight Rating) of
your vehicle is 8,500 lb (3 855 kg) or above, your
vehicle has single stage airbags. If the GVWR
is below 8,500 lb (3 855 kg), your vehicle has dual
stage airbags. You can nd the GVWR on thecertication label on the rear edge of the driver’s
door. SeeLoading Your Vehicle on page 425
for more information.
Single Stage Airbags
If your vehicle has frontal airbags with single stage
deployment and your vehicle goes straight into
a wall that does not move or deform, the threshold
level is about 12 to 16 mph (19 to 26 km/h). The
threshold level can vary, however, with specic
vehicle design, so that it can be somewhat above
or below this range.
Dual Stage Airbags
If your vehicle has frontal airbags with dual stage
deployment, the amount of restraint will adjust
according to crash severity. Your vehicle has
electronic frontal sensors which help the sensing
system distinguish between a moderate 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 23 mph (29 to 37 km/h).
