belt GMC SIERRA 2007 Workshop Manual

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, slightly recline 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.Securing a Child Restraint in the
Right Front Seat Position (Heavy
Duty Crew Cab Only)
Your vehicle has a right front passenger airbag.
Neverput a rear-facing child restraint in the
right front passenger’s seat. Here is why:
{CAUTION:
A child in a rear-facing child restraint can
be seriously injured or killed if the right
front passenger’s airbag inates. This is
because the back of the rear-facing child
restraint would be very close to the
inating airbag. Always secure a
rear-facing child restraint in a rear seat.
A rear seat is a safer place to secure a
forward-facing child restraint. If you need to
secure a forward-facing child restraint in the right
front seat position, seeWhere to Put the
Restraint on page 56.
80

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

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).
90

The threshold level can vary, however, with
specic vehicle design, so that it can be somewhat
above or below this range. Vehicle’s with dual
stage airbags also have a sensor which enables
the sensing system to monitor the position of
the driver seat. The seat position sensor provides
information which is used to determine if the
airbags should deploy at a reduced level or at full
deployment.
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 roof-mounted rollover
airbag, the sensing system detects that the
vehicle is about to roll over or has been in a severe
frontal impact or a moderate to severe side
impact. 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 rollover 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.
Airbags supplement 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 rollover airbags would not help you
in many types of collisions, including many
frontal or near frontal collisions, and rear impacts.
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 vehicles
with roof-mounted rollover airbags.
91

This switch should only be turned to the off
position if the person in the right front passenger’s
position is a member of a passenger risk group
identied by the national government as follows:
Infant.An infant (less than 1 year old)
must ride in the front seat because:

My vehicle has no rear seat;
My vehicle has a rear seat too small to
accommodate a rear-facing infant seat; or
The infant has a medical condition which,
according to the infant’s physician, makes
it necessary for the infant to ride in the front
seat so that the driver can constantly
monitor the child’s condition.
Child age 1 to 12.A child age 1 to 12 must
ride in the front seat because:

My vehicle has no rear seat;
Although children ages 1 to 12 ride in the rear
seat(s) whenever possible, children
ages 1 to 12 sometimes must ride in the front
because no space is available in the rear
seat(s) of my vehicle; or
The child has a medical condition which,
according to the child’s physician, makes
it necessary for the child to ride in the front
seat so that the driver can constantly monitor
the child’s condition.
Medical Condition.A passenger has a
medical condition which, according to his or
her physician:

Causes the passenger airbag to pose a
special risk for the passenger; and
Makes the potential harm from the passenger
airbag in a crash greater than the potential
harm from turning off the airbag and allowing
the passenger, even if belted, to hit the
dashboard or windshield in a crash.

Passenger Sensing System
If your vehicle has one of the indicators pictured in
the following illustrations, then your vehicle has
a passenger sensing system for the right front
passenger’s position, unless there is an airbag off
switch located in the glovebox. If there is an
airbag off switch, your vehicle does not have a
passenger sensing system. SeeAirbag Off Switch
on page 93for more information.
The passenger airbag status indicator will be
visible when you start your vehicle on the
overhead console.
The words ON and OFF, or the symbol for on and
off, will be visible during the system check.When the system check is complete, either the
word ON or the word OFF, or the symbol for on or
the symbol for off, will be visible. SeePassenger
Airbag Status Indicator on page 252.
The passenger sensing system will turn off the
right front passenger’s frontal airbag under certain
conditions. The driver’s airbags are not part of
the passenger sensing system.
The passenger sensing system works with
sensors that are part of the right front passenger’s
seat and safety belt. The sensors are designed
to detect the presence of a properly-seated
occupant and determine if the passenger’s frontal
airbag should be enabled (may inate) or not.
Accident statistics show that children are safer
if they are restrained in the rear rather than
the front seat.
We recommend that children be secured in a rear
seat, including: an infant or a child riding in a
rear-facing child restraint; a child riding in a
forward-facing child seat; an older child riding in a
booster seat; and children, who are large
enough, using safety belts.
