If the LOW ENG OIL LEVEL message appears on
the instrument panel, it means you need to check
your engine oil level right away. For more information,
see ªLow Oil Level Messageº in the Index.
You should check your engine oil level regularly; this is
an added reminder.
Checking Engine Oil
It's a good idea to check your engine oil every time you
get fuel. In order to get an accurate reading, the oil must
be warm and the vehicle must be on level ground.

The engine oil dipstick handle is the yellow loop located
near the front of the engine. See ªEngine Compartment
Overviewº in the Index for more information on location.

Turn off the engine and give the oil several minutes to
drain back into the oil pan. If you don't, the oil dipstick
might not show the actual level.
Pull out the dipstick and clean it with a paper towel or
cloth, then push it back in all the way. Remove it again,
keeping the tip down, and check the level.

When to Add Engine Oil
If the oil is at or below the lower mark, then you'll need
to add at least one quart of oil. But you must use the
right kind. This part explains what kind of oil to use. For
crankcase capacity, see ªCapacities and Specificationsº
in the Index.
NOTICE:
Don't add too much oil. If your engine has so much
oil that the oil level gets above the cross
-hatched
area that shows the proper operating range, your
engine could be damaged.

The engine oil fill cap is located toward the front of
the engine near the yellow
-looped engine oil dipstick
handle. See ªEngine Compartment Overviewº in the
Index for more information on location.
Be sure to fill it enough to put the level somewhere in
the proper operating range. Push the dipstick all the way
back in when you're through.
What Kind of Engine Oil to Use
Oils recommended for your vehicle can be identified by
looking for the starburst symbol.
This symbol indicates that the oil has been certified by
the American Petroleum Institute (API). Do not use any
oil which does not carry this starburst symbol.
If you change your own oil,
be sure you use oil that has
the starburst symbol on the
front of the oil container.
If you have your oil
changed for you, be sure
the oil put into your engine
is American Petroleum
Institute certified for
gasoline engines.
You should also use the proper viscosity oil for your
vehicle, as shown in the following chart:

6-15
3400 (Code E) V6 EngineAs in the chart shown previously, if you have the
3400 V6 engine, SAE 5W
-30 is best for your vehicle.
However, you can use SAE 10W
-30 if it's going to be
0
F (
-18
C) or above. These numbers on an oil
container show its viscosity, or thickness. Do not use
other viscosity oils, such as SAE 20W
-50.

6-16
As shown in the following chart, if you have the
3800 V6 engine, SAE 10W
-30 is best for your vehicle.
However, you can use SAE 5W
-30 if it's going to be
colder than 60
F (16
C) 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
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 10,000 miles (16 000 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 10,000 miles
(16 000 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 CHANGE ENGINE OIL message whenever
the oil is changed.

How to Reset the Change Engine Oil Message
After changing the engine oil, the system must be reset.
To reset the CHANGE ENGINE OIL message use one
of the following procedures:
Using the RDS Radio (If Equipped)
1. Turn the ignition to ACC or ON, with the radio off.
2. Press and hold the DISP button on the radio for at
least five seconds until SETTINGS is displayed.
3. Press the SEEK up or down arrow to scroll through
the main menu.
4. Scroll until OIL LIFE appears on the display.
5. Press the PREV or NEXT button to enter the
submenu. RESET will be displayed.
6. Press the DISP button to reset. A chime will be heard
to verify the new setting and DONE will be
displayed for one second.
7. Once the message has been reset, scroll until EXIT
appears on the display.
8. Press the DISP button to exit programming.
A chime will be heard to verify the exit.Using the Accelerator Pedal
1. Turn the ignition to ON, with the engine off.
2. Fully press and release the accelerator pedal three
times within five seconds. If the CHANGE ENGINE
OIL message flashes, the system is reset. However,
if it stays on, it did not reset. You'll need to repeat
the reset procedure.
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 engine air cleaner/filter is located on the driver's
side of the engine compartment. See ªEngine
Compartment Overviewº in the Index for more
information on location.
To check or replace the engine air cleaner/filter do
the following:
1. Loosen the two clips on the top of the engine air
cleaner/filter housing and lift the filter cover tabs
out of the housing.
2. Push the filter cover housing toward the engine,
compressing the duct convolutes.
3. Pull out the filter.
4. Check or install a new engine air cleaner/filter.
See ªNormal Maintenance Replacement Partsº
in the Index.
5. To reinstall the cover, position the tabs through the
slots on the housing. A notch on the sides of the
filter cover will indicate the correct engagement.
Re
-clip 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.
