Before closing the hood, be sure that all the filler
caps are on properly. Then pull the hood down and
close it firmly.
Engine Oil
If the LOW OIL message
appears on the instrument
panel, it means you need to
check your engine oil level
right away. For more
information, see ªLow Oil
Lightº 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.

6-12
When to Add Engine Oil
If the oil is at or below the ADD 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 FULL
mark that shows the proper operating range,
your engine could be damaged.
The engine oil fill cap is
located toward the front of
the engine compartment
near the yellow looped
engine oil dipstick. 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.

6-13 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:

6-14
As in the chart shown previously, SAE 5W-30 is best for
your vehicle. However, you can use SAE 10W
-30 if it's
going to be 0F (
-18C) or above. 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 OIL light whenever the oil
is changed.

6-15
How to Reset the CHANGE OIL Light
After changing the engine oil, the system must be reset.
To reset the CHANGE OIL light after an oil change do
the following:
1. With the ignition key turned to ON, but the engine
off, fully push and release the accelerator pedal
slowly three times within five seconds.
If the CHANGE OIL light flashes, the system
is resetting.
2. Turn the key to OFF after the light has finished
flashing, then start the vehicle. If the CHANGE OIL
light comes back on, the engine oil life system has
not reset. Repeat the 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 near the front 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. Using a screwdriver, loosen the bolt on the air duct
clamp from the throttle body.
2. Remove the air duct from the throttle body.
3. Unhook the two hold-down clips located on the air
box cover.
4. Lift the air box cover and air duct assembly away
from the air box, toward the engine.

6-17
5. Hold the air box cover and air duct assembly up in
position while removing the old air filter element
from the air box.
6. To install the new engine air cleaner/filter, reverse
the steps.Be sure the tabs on the cover are inserted into the air
box slots.
Refer to the Maintenance Schedule to determine when to
replace the air filter.
See ªScheduled Maintenance Servicesº in the Index.
