Service
Your dealer knows your vehicle best and wants you to
be happy with it. We hope you'll go to your dealer for
all your service needs. You'll get genuine GM parts and
GM
-trained and supported service people.
We hope you'll want to keep your GM vehicle all GM.
Genuine GM parts have one of these marks:
Doing Your Own Service Work
If you want to do some of your own service work, you'll
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, see ªService
and Owner Publicationsº in the Index.
Your vehicle has an air bag system. Before attempting to
do your own service work, see ªServicing Your Air
Bag
-Equipped Vehicleº in the Index.
You should keep a record with all parts receipts and list
the mileage and the date of any service work you
perform. See ªMaintenance Recordº in the Index.

6-3
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. ªEnglishº and ªmetricº
fasteners can be easily confused. If you use
the wrong fasteners, parts can later break
or fall off. You could be hurt.
Adding Equipment to the Outside of
Your Vehicle
Things you might add to the outside of your vehicle can
affect the airflow 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
The 8th digit of your vehicle identification number
(VIN) shows the code letter for your engine. You will
find the VIN at the top left of your instrument panel.
(See ªVehicle Identification Numberº in the Index.)
If you have the 3800 V6 engine (VIN Code K), use
regular unleaded gasoline rated at 87 octane or higher.
If you're using fuel rated at the recommended octane or
higher and you hear heavy knocking, your engine needs
service. But don't worry if you hear a little pinging
noise when you're accelerating or driving up a hill.
That's normal, and you don't have to buy a higher
octane fuel to get rid of pinging. It's the heavy, constant
knock that means you have a problem.
If you have the 3800 Supercharged V6 engine
(VIN Code 1), use premium unleaded gasoline rated at
91 octane or higher. With the 3800 Supercharged
engine, in an emergency, you may be able to use a lower
octane
-- as low as 87 -- if heavy knocking does not
occur. If you are using 91 or higher octane unleaded
gasoline and you hear heavy knocking, your engine
needs service.

As shown in the chart, SAE 10W-30 is best for your
vehicle. However, you can use SAE 5W
-30 if it's going
to be colder than 60F (16C) before your next oil
change. When it's very cold, you should use SAE
5W
-30. These numbers on an oil container show its
viscosity, or thickness. Do not use other viscosity oils,
such as SAE 20W
-50.
NOTICE:
Use only engine oil with the American Petroleum
Institute Certified For Gasoline Engines
starburst symbol. Failure to use the
recommended oil can result in engine damage not
covered by your warranty.
GM Goodwrench oil meets all the requirements for
your vehicle.
If you are in an area where the temperature falls below
-20F (-29C), consider using either an SAE 5W-30
synthetic oil or an SAE 0W
-30 oil. Both will provide
easier cold starting and better protection for your engine
at extremely low temperatures.
Engine Oil Additives
Don't add anything to your oil. The recommended oils
with the starburst symbol are all you will need for good
performance and engine protection.
When to Change Engine Oil (Vehicles
Without the GM Oil Life System)
If any one of these is true for you, use the short trip/city
maintenance schedule:
Most trips are less than 5 to 10 miles (8 to 16 km).
This is particularly important when outside
temperatures are below freezing.
Most trips include extensive idling (such as frequent
driving in stop
-and-go traffic).
Most trips are through dusty areas.
You frequently tow a trailer or use a carrier on top of
your vehicle.
The vehicle is used for delivery service, police, taxi
or other commercial application.
Driving under these conditions causes engine oil to
break down sooner. If any one of these is true for your
vehicle, then you need to change your oil and filter
every 3,000 miles (5 000 km) or 3 months
-- whichever
occurs first.
Page 290 of 402

6-15
If none of them is true, use the long trip/highway
maintenance schedule. Change the oil and filter every
7,500 miles (12 500 km) or 12 months
-- whichever
occurs first. Driving a vehicle with a fully warmed
engine under highway conditions causes engine oil to
break down slower.
When to Change Engine Oil (Vehicles With
the GM Oil Life System Option)
If so equipped, your vehicle has a computer that lets you
know when to change your engine oil. This is not based
on mileage, but on engine revolutions and engine
operating temperature. When the computer has
calculated that the oil needs changing, the GM Oil Life
System will indicate that a change is necessary.
The mileage between oil and filter changes will vary
depending on how you drive your vehicle
-- usually
between 3,000 miles (5 000 km) and 7,500 miles
(12 500 km) since your last oil and filter change.
Under severe conditions, the system may come on
before 3,000 miles (5 000 km). Never drive your vehicle
more than 7,500 miles (12 500 km) or 12 months
(whichever occurs first) without an oil change.
The system won't detect dust in the oil. So, if you drive
in a dusty area, be sure to change your oil and filter
every 3,000 miles (5 000 km) or sooner. Remember to
reset the Oil Life System whenever the oil is changed.How to Reset the Oil Life System (If Equipped)
Always reset the engine oil life to 100% after every oil
change. It will not reset itself. To reset the Oil Life
System, press and hold the RESET button for more than
five seconds while the OIL LIFE is being displayed on
the DIC. The oil life will change to 100%.
What to Do with Used Oil
Did you know that used engine oil contains certain
elements that may be unhealthy for your skin and could
even cause cancer? Don't let used oil stay on your skin
for very long. Clean your skin and nails with soap and
water, or a good hand cleaner. Wash or properly throw
away clothing or rags containing used engine oil.
(See the manufacturer's warnings about the use and
disposal of oil products.)
Used oil can be a real threat to the environment. If you
change your own oil, be sure to drain all free
-flowing oil
from the filter before disposal. Don't ever dispose of oil
by putting it in the trash, pouring it on the ground,
into sewers, or into streams or bodies of water. Instead,
recycle it by taking it to a place that collects used oil.
If you have a problem properly disposing of your used
oil, ask your dealer, a service station or a local recycling
center for help.

Engine Air Cleaner/Filter
The air cleaner/filter is on the driver's side of the engine
compartment. To check or replace the air cleaner/filter:
1. Loosen the two clips on top of the air cleaner
housing and lift the filter cover tabs out of
the housing.
2. Push the filter housing cover toward the engine,
compressing the hose.3. Pull out the filter.
4. Replace the air filter and make sure the filter cover
tabs position through the slots in the housing.
A notch on the sides of the filter cover will indicate
the correct engagement.
5. Fasten the two clips on the top of the housing when
you are finished.
Refer to the Maintenance Schedule to determine when to
replace the air filter.
See ªScheduled Maintenance Servicesº in the Index.
CAUTION:
Operating the engine with the air cleaner/filter
off can cause you or others to be burned. The air
cleaner not only cleans the air, it stops flame if
the engine backfires. If it isn't there, and the
engine backfires, you could be burned. Don't
drive with it off, and be careful working on the
engine with the air cleaner/filter off.
Page 292 of 402

6-17
NOTICE:
If the air cleaner/filter is off, a backfire can cause
a damaging engine fire. And, dirt can easily get
into your engine, which will damage it. Always
have the air cleaner/filter in place when
you're driving.
Passenger Compartment Air Filter
(If Equipped)
If your vehicle has this feature, the outside air entering
the vehicle is routed through a filter. The filter removes
certain particles from the air, including pollen and dust
particles. Reductions in airflow, which may occur more
quickly in dusty areas, indicate that the filter needs to be
replaced early.
The particle filter is located
under a removeable panel
located at the base of the
windshield on the
passenger's side.
The filter should be replaced as part of the routine
scheduled maintenance. See ªMaintenance Scheduleº in
the Index for replacement intervals. See your dealer for
details on changing the filter.
Once you remove your filter, if you choose not to
replace it, it will not damage your vehicle. However, the
air will no longer be filtered.

Supercharger Oil
Unless you are
technically qualified
and have the proper
tools, you should let
your dealer or a
qualified service
center perform
this maintenance.
When to Check
Check oil level every 30,000 miles (50 000 km) or every
36 months, whichever occurs first.
What Kind of Oil to Use
Use only the recommended supercharger oil. See
ªRecommended Fluids and Lubricantsº in the Index.
How to Check and Add Oil
Check oil only when the engine is cold. Allow the
engine to cool two to three hours after running.
CAUTION:
If you remove the supercharger oil fill plug while
the engine is hot, pressure may cause hot oil to
blow out of the oil fill hole. You may be burned.
Do not remove the plug until the engine cools.
1. Clean the area around the oil fill plug before
removing it.
2. Remove the oil fill plug using a 3/16 inch
Allen wrench.
3. The oil level is correct when it just reaches the
bottom of the threads of the inspection hole.
4. Replace the oil plug with the O
-ring in place.
