airbag GMC SIERRA 2007 Repair Manual

Your vehicle’s original equipment tires are listed
on the Tire and Loading Information Label.
This label is attached to the vehicle’s center pillar
(B-pillar). SeeLoading Your Vehicle on page 425,
for more information about the Tire and Loading
Information Label and its location on your vehicle.
Different Size Tires and Wheels
If you add wheels or tires that are a different size
than your original equipment wheels and tires,
this could affect the way your vehicle performs,
including its braking, ride and handling
characteristics, stability, and resistance to rollover.
Additionally, if your vehicle has electronic
systems such as anti-lock brakes, rollover airbags,
traction control, and electronic stability control,
the performance of these systems can be affected.
{CAUTION:
If you add different sized wheels, your
vehicle may not provide an acceptable
level of performance and safety if tires not
recommended for those wheels are
selected. You may increase the chance
that you will crash and suffer serious
injury. Only use GM specic wheel and
tire systems developed for your vehicle,
and have them properly installed by a GM
certied technician.
SeeBuying New Tires on page 568and
Accessories and Modications on page 486for
additional information.

Electrical System
Add-On Electrical Equipment
Notice:Do not add anything electrical to your
vehicle unless you check with your dealer
rst. Some electrical equipment can damage
your vehicle and the damage would not
be covered by your warranty. Some add-on
electrical equipment can keep other
components from working as they should.
Add-on equipment can drain your vehicle’s battery,
even if your vehicle is not operating.
Your vehicle has an airbag system. Before
attempting to add anything electrical to your
vehicle, seeServicing Your Airbag-Equipped
Vehicle on page 102.
Windshield Wiper Fuses
The windshield wiper motor is protected by an
internal circuit breaker and a fuse. If the motor
overheats due to heavy snow, etc., the wiper will
stop until the motor cools. If the overload is
caused by some electrical problem and not snow,
etc., be sure to get it xed.
Power Windows and Other Power
Options
Circuit breakers protect the power windows and
other power accessories. If the current load is too
heavy, the circuit breaker opens and then
closes after a cool down period, protecting the
circuit until the problem is xed or goes away.
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected
from short circuits by a combination of fuses,
circuit breakers and fusible thermal links.
This greatly reduces the chance of res caused by
electrical problems.
Look at the silver-colored band inside the fuse. If
the band is broken or melted, replace the fuse.
Be sure you replace a bad fuse with a new one of
the identical size and rating.
If you ever have a problem on the road and do not
have a spare fuse, you can borrow one that has the
same amperage. Just pick some feature of your
vehicle that you can get along without, like the radio
or cigarette lighter, and use its fuse if it is the
correct amperage. Replace it as soon as you can.

(e)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.
Have any torn or frayed safety belts replaced. Also
look for any opened or broken airbag coverings,
and have them repaired or replaced. The
airbag system does not need regular maintenance.
(f)Lubricate all key lock cylinders, body door
hinges, hood latch assembly, secondary latch,
pivots, spring anchor, release pawl, tailgate hinges,
tailgate linkage, tailgate handle pivot points,
latch bolt, fuel door hinge, locks, and folding seat
hardware. More frequent lubrication may be
required when exposed to a corrosive
environment. Applying silicone grease on
weatherstrips with a clean cloth will make them
last longer, seal better, and not stick or squeak.
(g)Check vent hose at transfer case for kinks and
proper installation. Check to be sure vent hose
is unobstructed, clear, and free of debris.(h)Change automatic transmission uid and lter
if the vehicle Gross Vehicle Weight Rating
(GVWR) is over 8600 lbs or if the vehicle is mainly
driven under one or more of these conditions:
In heavy city traffic where the outside
temperature regularly reaches 90°F (32°C) or
higher.
In hilly or mountainous terrain.
When doing frequent trailer towing.
Uses such as found in taxi, police or delivery
service.
(i)Drain, ush, and rell cooling system. This
service can be complex; you should have
your dealer perform this service. See Engine
Coolant on page 513 for what to use. Inspect
hoses. Clean radiator, condenser, pressure cap,
and ller neck. Pressure test the cooling
system and pressure cap.
(j)A uid loss in any vehicle system could indicate
a problem. Have the system inspected and
repaired and the uid level checked. Add uid if
needed.

Vehicle Data Collection and Event
Data Recorders
Your vehicle, like other modern motor vehicles,
has a number of sophisticated computer
systems that monitor and control several
aspects of the vehicle’s performance. Your
vehicle uses on-board vehicle computers
to monitor emission control components to
optimize fuel economy, to monitor conditions
for airbag deployment and, if the vehicle
has the Anti-lock Brake System (ABS), to
provide anti-lock braking and to help the driver
control the vehicle in difficult driving
situations. Some information may be stored
during regular operations to facilitate repair of
detected malfunctions; other information is
stored only in a crash event by computer
systems, such as those commonly called Event
Data Recorders (EDR).
In a crash event, computer systems, such as
the airbag Sensing and Diagnostic Module
(SDM) in your vehicle may record information
about the condition of the vehicle and how
it was operated, such as data related to engine
speed, brake application, throttle position,vehicle speed, safety belt usage, airbag
readiness, airbag performance, and the
severity of a collision. This information has
been used to improve vehicle crash
performance and may be used to improve
crash performance of future vehicles and
driving safety. Unlike the data recorders on
many airplanes, these on-board systems do not
record sounds, such as conversation of
vehicle occupants.
To read this information, special equipment is
needed and access to the vehicle or the
device that stores the data is required. GM will
not access information about a crash event
or share it with others other than:
with the consent of the vehicle owner or, if
the vehicle is leased, with the consent of
the lessee,
in response to an official request of police
or similar government office,
as part of GM’s defense of litigation
through the discovery process, or
as required by law.
