Low Engine Oil Level Message
Your vehicle may be equipped with a low engine oil
level message.
This message is displayed for 60 seconds at the start of
each ignition cycle when the engine oil level is low.
Four chimes will also sound.
When the ignition is turned off, this message will be
displayed again for three seconds to remind you
that your engine oil level is low. Be sure to have your
vehicle serviced right away.
See
Engine Oil on page 5-16on how to check the oil
level and for what type of oil to add.
Change Engine Oil Message
This message is displayed when the engine oil needs to
be changed. It will appear for 60 seconds.
Once the engine oil has been changed, the CHANGE
ENGINE OIL message must be reset. Until it is
reset, this message will be displayed for 60 seconds
each time you start the engine. For more information on
resetting the system, see ªHow to Reset the Change
Engine Oil Messageº under

What Kind of Engine Oil to Use
Oils recommended for your vehicle can be identi®ed by
looking for the starburst symbol.
This symbol indicates that the oil has been certi®ed by
the American Petroleum Institute (API). Do not use
any oil which does not carry this starburst symbol.
If you choose to perform
the engine oil change
service yourself, be sure
the oil you use 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 certi®ed
for gasoline engines.
You should also use the proper viscosity oil for your
vehicle, as shown in the viscosity chart.
3400 (Code E) V6 Engine
5-18

As in the chart shown previously, if you have the
3400 V6 engine, SAE 5W-30 is the only viscosity grade
recommended for your vehicle. You should look for
and use only oils which have the API Starburst symbol
and which are also identi®ed as SAE 5W-30. If you
cannot ®nd such SAE 5W-30 oils, you can use an
SAE 10W-30 oil which has the API Starburst symbol, if
it's going to be 0ÉF (-18ÉC) or above. Do not use
other viscosity grade oils, such as SAE 10W-40 or
SAE 20W-50 under any conditions.
As shown in the following chart, if you have the
3800 V6 engine, SAE 10W-30 is the viscosity grade
recommended for your vehicle. However, you can use
SAE 5W-30 if it's going to be colder than 60ÉF
(16ÉC) before your next oil change. When it's very cold,
colder than 0ÉF (-18ÉC), you should use an SAE 5W-30
oil. These numbers on an oil container show its
viscosity, or thickness. Do not use other viscosity grade
oils, such as SAE 10W-40 or SAE 20W-50 under any
conditions.
3800 (Code K) V6 Engine
5-19

Notice:Use only engine oil with the American
Petroleum Institute Certi®ed For Gasoline Engines
starburst symbol. Failure to use the recommended
oil can result in engine damage not covered by
your warranty.
GM Goodwrench
žoil meets all the requirements for
your vehicle.
If you are in an area of extreme cold, where the
temperature falls below-20ÉF (-29ÉC), it is
recommended that you use 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
(GM Oil Life System)
Your vehicle has a computer system that lets you
know when to change the engine oil and ®lter. This is
based on engine revolutions and engine temperature,and not on mileage. Based on driving conditions, the
mileage at which an oil change will be indicated can vary
considerably. For the oil life system to work properly,
you must reset the system every time the oil is changed.
When the system has calculated that oil life has been
diminished, it will indicate that an oil change is
necessary. A CHANGE ENGINE OIL message will
come on. Change your oil as soon as possible within
the next two times you stop for fuel. 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 Change Engine Oil
Message
The GM 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 ENGINE OIL message being turned on, reset
the system.
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 Radio
1. Turn the ignition to ACC or ON, with the radio off.
2. Press and hold the TUNE DISP button on the radio
for at least ®ve seconds until SETTINGS is
displayed.
3. Press the SEEK PSCAN up or down arrow to scroll
through the main menu.
4. Scroll until OIL LIFE appears on the display.
5. Press the 1 PREV or 2 NEXT buttons to enter the
submenu. RESET will be displayed.
6. Press the TUNE 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 indicator has been reset, scroll until EXIT
appears on the display.
8. Press the TUNE DISP button to exit programming.
A chime will be heard to verify the exit.
5-21

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 ®ve seconds. If the CHANGE ENGINE
OIL message ¯ashes, 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
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 dispose of 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 threat to the environment. If you
change your own oil, be sure to drain all the oil from the
®lter before disposal. Never 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
When to Inspect the Engine Air
Cleaner/Filter
Inspect the air cleaner/®lter at every oil change and
replace at the ®rst oil change after 25,000 miles
(40,000 km).
How to Inspect the Engine Air
Cleaner/Filter
To inspect the air cleaner/®lter remove the ®lter from the
vehicle and lightly shake ®lter to release loose dust
and dirt. If the ®lter remains ªcakedº with dirt, a new ®lter
is required.
See
Engine Compartment Overview on page 5-12for
location of air cleaner/®lter.
