5-2 Service and Appearance Care
Service
For service and parts needs, visit
your dealer/retailer. You will receive
genuine GM parts and GM-trained
and supported service people.
Genuine GM parts have one
of these marks:
Accessories and
Modi cations
When non-dealer/non-retailer
accessories are added to the vehicle,
they can affect vehicle performance
and safety, including such things
as airbags, braking, stability, ride
and handling, emissions systems,
aerodynamics, durability, and
electronic systems like antilock
brakes, traction control, and stability
control. Some of these accessories
could even cause malfunction or
damage not covered by the vehicle
warranty.
Damage to vehicle components
resulting from the installation or use
of non-GM certi ed parts, including
control module modi cations, arenot covered under the terms of the
vehicle warranty and may affect
remaining warranty coverage for
affected parts.
GM Accessories are designed to
complement and function with other
systems on the vehicle. Your GM
dealer/retailer can accessorize
the vehicle using genuine GM
Accessories. When you go to your
GM dealer/retailer and ask for
GM Accessories, you will know that
GM-trained and supported service
technicians will perform the
work using genuine GM
Accessories.

Airbag-Equipped Vehicle on
page 1-58.

California Proposition 65
Warning
Most motor vehicles, including this
one, contain and/or emit chemicals
known to the State of California
to cause cancer and birth defects or
other reproductive harm. Engine
exhaust, many parts and systems
(including some inside the vehicle),
many uids, and some component
wear by-products contain and/or
emit these chemicals.
California Perchlorate
Materials Requirements
Certain types of automotive
applications, such as airbag
initiators, seat belt pretensioners,
and lithium batteries contained in
remote keyless transmitters, may
contain perchlorate materials.
Special handling may be necessary.
For additional information, see
www.dtsc.ca.gov/hazardouswaste/
perchlorate.
Doing Your Own
Service Work
{CAUTION
You can be injured and the
vehicle could be damaged if you
try to do service work on a vehicle
without knowing enough about it.
Be sure you have sufficient
knowledge, experience, the
proper replacement parts, and
tools before attempting any
vehicle maintenance task.
Be sure to use the proper
nuts, bolts, and other
fasteners. English and metric
fasteners can be easily
confused. If the wrong
fasteners are used, parts
can later break or fall off.
You could be hurt.
If doing some of your own service
work, use the proper service
manual. It tells you much moreabout how to service the vehicle
than this manual can. To order the
proper service manual, see
Service Publications Ordering
Information on page 7-15.
This vehicle has an airbag system.
Before attempting to do your
own service work, seeServicing
Your Airbag-Equipped Vehicle
on page 1-57.
Keep a record with all parts receipts
and list the mileage and the date
of any service work performed. See
Maintenance Record on page 6-16.Adding Equipment to the
Outside of the Vehicle
Things added to the outside of
the vehicle can affect the air ow
around it. This can cause wind noise
and can affect fuel economy and
windshield washer performance.
Check with your dealer/retailer
before adding equipment to
the outside of the vehicle.
5-4 Service and Appearance Care
Fuel
Use of the recommended fuel
is an important part of the proper
maintenance of this vehicle. To help
keep the engine clean and maintain
optimum vehicle performance, we
recommend the use of gasoline
advertised as TOP TIER Detergent
Gasoline.
Gasoline Octane
Use regular unleaded gasoline with a
posted octane rating of 87 or higher.
If the octane rating is less than 87,
you might notice an audible knocking
noise when you drive, commonly
referred to as spark knock. If this
occurs, use a gasoline rated at
87 octane or higher as soon as
possible. If you are using gasoline
rated at 87 octane or higher and you
hear heavy knocking, the engine
needs service.
Gasoline Speci cations
At a minimum, gasoline should
meet ASTM speci cation D 4814
in the United States or CAN/
CGSB-3.5 or 3.511 in Canada.
Some gasolines contain an
octane-enhancing additive called
methylcyclopentadienyl manganese
tricarbonyl (MMT). We recommend
against the use of gasolines
containing MMT. SeeAdditives on
page 5-5for additional information.
California Fuel
If the vehicle is certi ed to meet
California Emissions Standards,
it is designed to operate on fuels
that meet California speci cations.
See the underhood emission control
label. If this fuel is not available in
states adopting California emissions
standards, the vehicle will operate
satisfactorily on fuels meeting federal
speci cations, but emission control
system performance might be
affected. The malfunction indicator
lamp could turn on and the vehiclemight fail a smog-check test. See
Malfunction Indicator Lamp on
page 3-39. If this occurs, return to
your authorized dealer/retailer for
diagnosis. If it is determined that the
condition is caused by the type of
fuel used, repairs might not be
covered by the vehicle warranty.
Additives
To provide cleaner air, all gasolines
in the United States are now required
to contain additives that help prevent
engine and fuel system deposits
from forming, allowing the emission
control system to work properly.
In most cases, you should not have
to add anything to the fuel. However,
some gasolines contain only the
minimum amount of additive required
to meet U.S. Environmental
Protection Agency regulations.
To help keep fuel injectors and
intake valves clean, or if the vehicle
experiences problems due to dirty
injectors or valves, look for gasoline
that is advertised as TOP TIER
Detergent Gasoline.
Service and Appearance Care 5-5
For customers who do not use TOP
TIER Detergent Gasoline regularly,
one bottle of GM Fuel System
Treatment PLUS, added to the fuel
tank at every engine oil change,
can help clean deposits from fuel
injectors and intake valves. GM Fuel
System Treatment PLUS is the only
gasoline additive recommended by
General Motors.
Also, your dealer/retailer has
additives that will help correct and
prevent most deposit-related
problems.
Gasolines containing oxygenates,
such as ethers and ethanol, and
reformulated gasolines might
be available in your area. We
recommend that you use these
gasolines, if they comply with the
speci cations described earlier.
However, E85 (85% ethanol) and
other fuels containing more than
10% ethanol must not be used in
vehicles that were not designed for
those fuels.Notice:This vehicle was not
designed for fuel that contains
methanol. Do not use fuel
containing methanol. It can
corrode metal parts in the fuel
system and also damage plastic
and rubber parts. That damage
would not be covered under
the vehicle warranty.
Some gasolines that are
not reformulated for low
emissions can contain an
octane-enhancing additive called
methylcyclopentadienyl manganese
tricarbonyl (MMT); ask the attendant
where you buy gasoline whether the
fuel contains MMT. We recommend
against the use of such gasolines.
Fuels containing MMT can reduce
the life of spark plugs and the
performance of the emission control
system could be affected. The
malfunction indicator lamp might turn
on. If this occurs, return to your
dealer/retailer for service.Fuels in Foreign
Countries
If you plan on driving in another
country outside the United States or
Canada, the proper fuel might be
hard to nd. Never use leaded
gasoline or any other fuel not
recommended in the previous text
on fuel. Costly repairs caused
by use of improper fuel would not
be covered by the vehicle warranty.
To check the fuel availability, ask
an auto club, or contact a major oil
company that does business in
the country where you will be
driving.
