Using the Maintenance Schedule
We at General Motors want to help you keep your
vehicle in good working condition. But we do
not know exactly how you will drive it. You may
drive very short distances only a few times a week.
Or you may drive long distances all the time in
very hot, dusty weather. You may use your vehicle
in making deliveries. Or you may drive it to
work, to do errands, or in many other ways.
Because of all the different ways people use their
vehicles, maintenance needs vary. You may
need more frequent checks and replacements.
So please read the following and note how
you drive. If you have any questions on how to
keep your vehicle in good condition, see your
GM Goodwrench
®dealer.This schedule is for vehicles that:
carry passengers and cargo within
recommended limits. You will nd these limits
on the tire and loading information label.
SeeLoading Your Vehicle on page 390.

(a)Visually inspect brake lines and hoses for
proper hook-up, binding, leaks, cracks, chang,
etc. Inspect disc brake pads for wear and rotors for
surface condition. Inspect other brake parts,
including calipers, parking brake, etc.
(b)Visually inspect front and rear suspension and
steering system for damaged, loose, or missing
parts, signs of wear, or lack of lubrication. Inspect
power steering lines and hoses for proper
hook-up, binding, leaks, cracks, chang, etc.
Visually check constant velocity joints, rubber
boots, and axle seals for leaks.
(c)Visually inspect hoses and have them replaced
if they are cracked, swollen, or deteriorated.
Inspect all pipes, ttings, and clamps; replace with
genuine GM parts as needed. To help ensure
proper operation, a pressure test of the cooling
system and pressure cap and cleaning the outside
of the radiator and air conditioning condenser is
recommended at least once a year.
(d)Visually inspect wiper blades for wear or
cracking. Replace wiper blades that appear worn
or damaged or that streak or miss areas of
the windshield.(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, hood latch
assembly, secondary latch, pivots, spring anchor,
release pawl, rear compartment hinges, outer
liftgate handle pivot points, rear door detent link,
roller mechanism, liftgate handle pivot points, latch
bolt, fuel door hinge, cargo 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.
559

(h)Change automatic transmission uid and lter
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 449 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.
(k)Inspect system. Check all fuel and vapor lines
and hoses for proper hook-up, routing, and
condition. Check that the purge valve works
properly, if equipped. Replace as needed.(l)If you drive regularly under dusty conditions,
inspect the lter at each engine oil change.
(m)Visually inspect belt for fraying, excessive
cracks, or obvious damage. Replace belt if
necessary.
Owner Checks and Services
These owner checks and services should be
performed at the intervals specied to help
ensure the safety, dependability, and emission
control performance of your vehicle. Your
GM Goodwrench
®dealer can assist you with
these checks and services.
Be sure any necessary repairs are completed at
once. Whenever any uids or lubricants are added
to your vehicle, make sure they are the proper
ones, as shown inRecommended Fluids and
Lubricants on page 564.
At Each Fuel Fill
It is important to perform these underhood checks
at each fuel ll.

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 can
offer you one of the following:
Shuttle Service
Shuttle service is the preferred means of offering
Courtesy Transportation and participating
dealers 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 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.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 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, 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.
582

Additional Program Information
All program options, such as shuttle service, may
not be available at every dealer. Please contact
your dealer for specic information about
availability. All Courtesy Transportation
arrangements will be administered by appropriate
dealer 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.
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 so equipped, 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. If your vehicle is
equipped with StabiliTrak
®, steering performance,
including yaw rate, steering wheel angle, and
lateral acceleration, is also recorded. 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.
