fuel GMC SIERRA 2007 Repair Manual

(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.
630

(k)Inspect system. Check all fuel and vapor lines
and hoses for proper hook-up, routing, and
condition. Check that the purge valve, if the vehicle
has one, works properly. Replace as needed.
(l)Extreme Duty Service: Change transfer case
uid if the vehicle is mainly driven off-road in
four-wheel drive, or is used for heavy trailer towing.
Farming, mining, forestry, and Department of
Natural Resources (DNR) vehicles meet this
denition.
(m)During any maintenance, if a power washer is
used to clean mud and dirt from the underbody,
care should be taken to not directly spray the
transfer case output seals. High pressure water can
overcome the seals and contaminate the transfer
case uid. Contaminated uid will decrease the life
of the transfer case and should be replaced.
(n)Vehicles with diesel engine or with GVWR
above 10,000 lbs (4 536 kg) only: Inspect shields
for damage or looseness. Adjust or replace as
required. This is a Noise Emission Control Service.
Applicable to vehicles sold in the United States
and recommended for vehicles sold in Canada.
(p)If you drive regularly under dusty conditions,
inspect the lter or change indicator (if equipped)
at each engine oil change.(q)Visually inspect belt for fraying, excessive
cracks, or obvious damage. Replace belt if
necessary.

650

Scheduling Service Appointments
When your vehicle requires warranty service,
contact your dealer/retailer and request an
appointment. By scheduling a service appointment
and advising your service consultant of your
transportation needs, your dealer/retailer can help
minimize your inconvenience.
If your vehicle cannot be scheduled into the
service department immediately, keep driving it
until it can be scheduled for service, unless,
of course, the problem is safety-related. If it is,
please call your dealership/retailer, let them know
this, and ask for instructions.
If the dealer/retailer requests that you simply drop
the vehicle off for service, you are urged to do
so as early in the work day as possible to allow for
the same day repair.
Transportation Options
Warranty service can generally be completed
while you wait. However, if you are unable to wait,
GM helps to minimize your inconvenience by
providing several transportation options.
Depending on the circumstances, your
dealer/retailer can offer you one of the following:
Shuttle Service
Shuttle service is the preferred means of offering
Courtesy Transportation and participating
dealers/retailers can provide you with shuttle
service to get you to your destination with minimal
interruption of your daily schedule. This includes
one-way or round trip shuttle service within
reasonable time and distance parameters for the
dealer’s/retailer’s area.
Public Transportation or Fuel
Reimbursement
If your vehicle requires overnight warranty repairs,
and public transportation is used as ‘shuttle
service,’ the reimbursement is limited to the
associated shuttle allowance and must be
supported by original receipts.
654

In addition, for U.S. customers, should you arrange
transportation through a friend or relative, limited
reimbursement for reasonable fuel expenses may
be available. Claim amounts should reect actual
costs and be supported by original receipts.
Courtesy Rental Vehicle
Your dealer/retailer may arrange to provide you
with a courtesy rental vehicle or reimburse you for
a rental vehicle that you obtain if your vehicle is
kept for an overnight warranty repair. Rental
reimbursement will be limited and must be
supported by original receipts. This requires that
you sign and complete a rental agreement
and meet state/provincial, local, and rental vehicle
provider requirements. Requirements vary and
may include minimum age requirements, insurance
coverage, credit card, etc. You are responsible
for fuel usage charges and may also be
responsible for taxes, levies, usage fees,
excessive mileage, or rental usage beyond the
completion of the repair.
Generally it is not possible to provide a like-vehicle
as a courtesy rental.
Additional Program Information
All program options, such as shuttle service, may
not be available at every dealer/retailer. Please
contact your dealer/retailer for specic information
about availability. All Courtesy Transportation
arrangements will be administered by appropriate
dealer/retailer personnel.
General Motors reserves the right to unilaterally
modify, change or discontinue Courtesy
Transportation at any time and to resolve all
questions of claim eligibility pursuant to the terms
and conditions described herein at its sole
discretion.
655

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.
