Service
Your dealer knows your vehicle best and wants
you to be happy with it. We hope you will go
to your dealer for all your service needs. You will
get genuine GM parts and GM-trained and
supported service people.
We hope you will want to keep your GM vehicle
all GM. Genuine GM parts have one of these
marks:
Accessories and Modications
When you add non-GM accessories to your vehicle
they can affect your vehicle’s performance and
safety, including such things as, airbags, braking,
stability, ride and handling, emissions systems,
aerodynamics, durability, and electronic systems
like anti-lock brakes, traction control and
stability control. Some of these accessories may
even cause malfunction or damage not covered by
warranty.
GM Accessories are designed to complement and
function with other systems on your vehicle.
Your GM dealer can accessorize your vehicle
using genuine GM Accessories. When you go to
your GM dealer and ask for GM Accessories,
you will know that GM-trained and supported
service technicians will perform the work using
genuine GM Accessories.

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.
Doing Your Own Service Work
{CAUTION:
You can be injured and your 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 you attempt any
vehicle maintenance task.
Be sure to use the proper nuts, bolts,
and other fasteners. English and metric
fasteners can be easily confused. If you
use the wrong fasteners, parts can later
break or fall off. You could be hurt.
If you want to do some of your own service work,
you will want to use the proper service manual.
It tells you much more about how to service your
vehicle than this manual can. To order the
proper service manual, seeService Publications
Ordering Information on page 497.
364

Your vehicle has an airbag system. Before
attempting to do your own service work, see
Servicing Your Airbag-Equipped Vehicle on
page 58.
You should keep a record with all parts receipts
and list the mileage and the date of any service
work you perform. SeeMaintenance Record
on page 477.
Adding Equipment to the Outside of
Your Vehicle
Things you might add to the outside of your
vehicle can affect the airow around it. This may
cause wind noise and affect windshield washer
performance. Check with your dealer before
adding equipment to the outside of your vehicle.
Fuel
Use of the recommended fuel is an important part
of the proper maintenance of your vehicle. To
help keep your engine clean and maintain optimum
vehicle performance, GM recommends the use
of gasoline advertised as TOP TIER Detergent
Gasoline.
The 8th digit of your Vehicle Identication Number
(VIN) shows the code letter or number that
identies your engine. You will nd the VIN at the
top left of the instrument panel. SeeVehicle
Identication Number (VIN) on page 451.
365

Gasoline Octane
If your vehicle has the 4.6L V8 engine (VIN
Code A), use premium unleaded gasoline with a
posted octane rating of 91 or higher. You may also
use regular unleaded gasoline rated at 87
octane or higher, but your vehicle’s acceleration
may be slightly reduced, and you may notice
a slight audible knocking noise, commonly referred
to as spark knock. If the octane is less than 87,
you may notice a heavy knocking noise when you
drive. If this occurs, use a gasoline rated at 87
octane or higher as soon as possible. Otherwise,
you might damage your engine. If you are
using gasoline rated at 87 octane or higher and
you hear heavy knocking, your engine needs
service.
If your vehicle has the 4.4L V8 engine (VIN
Code D), use premium unleaded gasoline with a
posted octane rating of 91 or higher. For best
performance, use premium unleaded gasoline with
a posted octane rating of 93. In an emergency,you can use regular unleaded gasoline with an
octane rating of 87 or higher. If 87 octane fuel is
used, do not perform any aggressive driving
maneuvers such as wide open throttle applications.
You may also hear audible spark knock during
acceleration. Rell your tank with premium fuel as
soon as possible to avoid damaging your
engine. If you are using gasoline rated at 91
octane or higher and you hear heavy knocking,
your engine needs service.
Gasoline Specications
At a minimum, gasoline should meet ASTM
specication D 4814 in the United States or
CAN/CGSB-3.5 in Canada. Some gasolines may
contain an octane-enhancing additive called
methylcyclopentadienyl manganese tricarbonyl
(MMT). General Motors recommends against the
use of gasolines containing MMT. SeeAdditives
on page 367for additional information.
366

Gasolines containing oxygenates, such as ethers
and ethanol, and reformulated gasolines may
be available in your area. General Motors
recommends that you use these gasolines if they
comply with the specications 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:Your vehicle was not designed for
fuel that contains methanol. Do not use
fuel containing methanol. It can corrode metal
parts in your fuel system and also damage
the plastic and rubber parts. That damage
would not be covered under your warranty.Some gasolines that are not reformulated for low
emissions may contain an octane-enhancing
additive called methylcyclopentadienyl manganese
tricarbonyl (MMT); ask the attendant where you
buy gasoline whether the fuel contains MMT.
General Motors recommends against the use of
such gasolines. Fuels containing MMT can reduce
the life of spark plugs and the performance of
the emission control system may be affected. The
malfunction indicator lamp may turn on. If this
occurs, return to your dealer for service.
Fuels in Foreign Countries
If you plan on driving in another country outside
the United States or Canada, the proper fuel may
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 your
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.

When the system has calculated that oil life has
been diminished, it will indicate that an oil change
is necessary. A CHANGE OIL NOW message
in the DIC will come on. SeeDIC Warnings and
Messages on page 206. Change your oil as
soon as possible within the next 600 miles
(1 000 km). It is possible that, if you are driving
under the best conditions, the oil life system may
not indicate that an oil change is necessary for
over a year. However, your engine oil and
lter must be changed at least once a year and at
this time the system must be reset. Your dealer
has GM-trained service people who will perform
this work using genuine GM parts and reset
the system. It is also important to check your oil
regularly and keep it at the proper level.
If the system is ever reset accidentally, you must
change your oil at 3,000 miles (5 000 km)
since your last oil change. Remember to reset the
oil life system whenever the oil is changed.How to Reset the Engine Oil Life
System and the Oil Life Indicator
The Engine Oil Life System calculates when to
change your engine oil and lter based on vehicle
use. Anytime your oil is changed, reset the
system so it can calculate when the next oil
change is required. If a situation occurs where you
change your oil prior to a CHANGE OIL NOW
message in the DIC being turned on, reset
the system.
After the oil has been changed, the CHANGE OIL
NOW message and the oil life indicator must
be reset. To reset the message use the following
procedure:
1. Press the up or down arrow to scroll the DIC
to show OIL LIFE.
2. Once the XXX% ENGINE OIL LIFE menu item
is highlighted, press and hold the RESET
button until the percentage shows 100%.
If the percentage does not return to 100% or if
the CHANGE OIL NOW message comes
back on when you start your vehicle,
the engine oil life system has not reset.
Repeat the procedure.
