GMC SIERRA 2007 Owner's Manual

See “Safety Belts” and “Child Restraints” in the
Index for additional information about the
importance of proper restraint use.
{CAUTION:
If the airbag readiness light in the
instrument panel cluster ever comes on
and stays on, it means that something
may be wrong with the airbag system. If
this ever happens, have the vehicle
serviced promptly, because an adult-size
person sitting in the right front
passenger’s seat may not have the
protection of the airbag(s). SeeAirbag
Readiness Light on page 250for more on
this, including important safety
information.A thick layer of additional material, such as a
blanket or cushion, or aftermarket equipment such
as seat covers, seat heaters, and seat massagers
can affect how well the passenger sensing
system operates. You may want to consider not
using seat covers or other aftermarket equipment.
SeeAdding Equipment to Your Airbag-Equipped
Vehicle on page 102for more information
about modications that can affect how the system
operates.
{CAUTION:
Stowing of articles under the passenger’s
seat or between the passenger’s seat
cushion and seatback may interfere with
the proper operation of the passenger
sensing system.
101

Servicing Your Airbag-Equipped
Vehicle
Airbags affect how your vehicle should be
serviced. There are parts of the airbag system in
several places around your vehicle. You do
not want the system to inate while someone is
working on your vehicle. Your dealer and the
service manual have information about servicing
your vehicle and the airbag system. To purchase a
service manual, seeService Publications
Ordering Information on page 663.
{CAUTION:
For up to 10 seconds, after the ignition is
turned off and the battery is disconnected,
an airbag can still inate during improper
service. You can be injured if you are
close to an airbag when it inates.
CAUTION: (Continued)
CAUTION: (Continued)
Avoid yellow connectors. They are
probably part of the airbag system. Be
sure to follow proper service procedures,
and make sure the person performing
work for you is qualied to do so.
The airbag system does not need regular
maintenance.
Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to the front
or sides of the vehicle that could keep the
airbags from working properly?
A:Yes. If you add things that change your
vehicle’s frame, bumper system, height,
front end or side sheet metal, they may keep
the airbag system from working properly.
Also, the airbag system may not work properly
if you relocate any of the airbag sensors.
102

If you have any questions about this, you
should contact Customer Assistance before
you modify your vehicle. The phone numbers
and addresses for Customer Assistance
are in Step Two of the Customer Satisfaction
Procedure in this manual. SeeCustomer
Satisfaction Procedure on page 644.
Q:What if I added a snow plow? Will it keep
the airbags from working properly?
A:We have designed our airbag systems to work
properly under a wide range of conditions,
including snow plowing with vehicles that have
the optional Snow Plow Prep Package
(RPO VYU). But do not change or defeat the
snow plow’s “tripping mechanism.” If you
do, it can damage your snow plow and your
vehicle, and it may cause an airbag ination.
Q:Because I have a disability, I have to get
my vehicle modied. How can I nd out
whether this will affect my airbag system?
A:Changing or moving any parts of the
front seats, safety belts, the airbag sensing
and diagnostic module, rollover sensor
module, steering wheel, instrument panel,
overhead console, ceiling headliner, ceiling
and pillar garnish trim, roof-mounted rollover
airbag modules, or airbag wiring can affect the
operation of the airbag system. If you have
questions, call Customer Assistance. The
phone numbers and addresses for Customer
Assistance are in Step Two of the Customer
Satisfaction Procedure in this manual.
SeeCustomer Satisfaction Procedure on
page 644.
103

Restraint System Check
Checking the Restraint Systems
Now and then, make sure the safety belt reminder
light and all your belts, buckles, latch plates,
retractors and anchorages are working properly.
Look for any other loose or damaged safety
belt system parts. If you see anything that might
keep a safety belt system from doing its job, have
it repaired. Keep safety belts clean and dry.
SeeCare of Safety Belts on page 601for more
information.
Torn or frayed safety belts may not protect you in
a crash. They can rip apart under impact forces.
If a belt is torn or frayed, get a new one right away.Also look for any opened or broken airbag covers,
and have them repaired or replaced. The airbag
system does not need regular maintenance.
Notice:If you damage the covering for the
driver’s or the right front passenger’s airbag,
or the side impact airbag covering on the
ceiling near the side windows, the airbag may
not work properly. You may have to replace
the airbag module in the steering wheel, both
the airbag module and the instrument panel
for the right front passenger’s airbag, or
side impact airbag module and ceiling covering
for roof-mounted rollover airbags (if equipped).
Do not open or break the airbag coverings.
104

Replacing Restraint System Parts
After a Crash
{CAUTION:
A crash can damage the restraint systems
in your vehicle. A damaged restraint
system may not properly protect the
person using it, resulting in serious injury
or even death in a crash. To help make sure
your restraint systems are working
properly after a crash, have them inspected
and any necessary replacements made as
soon as possible.
If you have had a crash, do you need new belts or
LATCH system parts?
After a very minor collision, nothing may be
necessary. But if the belts were stretched, as they
would be if worn during a more severe crash,
then you need new parts.
If the LATCH system was being used during a
more severe crash, you may need new LATCH
system parts.If belts are cut or damaged, replace them.
Collision damage also may mean you will need to
have LATCH system, safety belt or seat parts
repaired or replaced. New parts and repairs may
be necessary even if the belt or LATCH system
was not being used at the time of the collision.
If an airbag inates, you will need to replace airbag
system parts. See the part on the airbag system
earlier in this section.
If the frontal airbags inate you will also need to
replace the driver and front passenger’s safety belt
retractor assembly. Be sure to do so. Then the
new retractor assembly will be there to help protect
you in a collision.
After a crash you may need to replace the driver
and front passenger’s safety belt retractor
assemblies, even if the frontal airbags have not
deployed. The driver and front passenger’s safety
belt retractor assemblies contain the safety belt
pretensioners. Have your safety belt pretensioners
checked if your vehicle has been in a collision,
or if your airbag readiness light stays on after you
start your vehicle or while you are driving. See
Airbag Readiness Light on page 250.
