Notice:Use only engine oil identied as meeting
GM Standard GM6094M and showing the American
Petroleum Institute Certied 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 of extreme cold, where the
temperature falls below−20°F (−29°C) 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
Do not add anything to your oil. The recommended oils
with the starburst symbol that meet GM Standard
GM6094M 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 miles (8 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).
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 lter
every 3,000 miles (5 000 km) or 3 months — whichever
occurs rst.
If none of them is true, use the long trip/highway
maintenance schedule. Change the oil and lter every
7,500 miles (12 500 km) or 12 months — whichever
occurs rst. Driving a vehicle with a fully warmed engine
under highway conditions will cause engine oil to
break down slower.

When to Change Engine Oil (Vehicles
With the GM Oil Life System)
If so equipped, 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.
An ENGINE OIL CHANGE SOON 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 Oil Life System
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 an
ENGINE OIL CHANGE SOON message being
turned on, reset the system.
Always reset the engine oil life to 100% after every oil
change. It will not reset itself. To reset the Oil Life
System, do the following:
1. Display OIL LIFE on the DIC.
2. Press and hold the RESET button for more than
ve seconds. The oil life will change to 100%.
3. Turn the key to OFF.
If the ENGINE OIL CHANGE SOON message comes
back on when you start your vehicle, the engine oil
life system has not reset. Repeat the 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.
Do not 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
SeeEngine Compartment Overview on page 5-14for
the location of the engine air cleaner/lter.
5-21

When to Inspect the Engine Air
Cleaner/Filter
Inspect the air cleaner/lter every 15,000 miles
(25 000 km) and replace every 30,000 miles
(50 000 km). If you are driving in dusty/dirty conditions,
inspect the lter at each oil change.
How to Inspect the Engine Air
Cleaner/Filter
To inspect the air cleaner/lter remove the lter from the
vehicle and lightly shake the lter to release loose
dust and dirt. If the lter remains caked with dirt, a new
lter is required.
To inspect or replace the engine air cleaner/lter do the
following:
1. Loosen the two clips on top of the engine air
cleaner/lter housing and lift the lter cover tabs out
of the housing.
2. Push the housing cover toward the engine,
compressing the hose.
3. Pull out the lter. Inspect or replace the engine air
cleaner/lter.4. To reinstall the housing cover, make sure the lter
cover tabs position through the slots in the housing.
A notch on the sides of the lter cover will indicate
the correct engagement.
5. Fasten the two clips on the top of the housing when
you are nished.
{CAUTION:
Operating the engine with the air cleaner/lter
off can cause you or others to be burned. The
air cleaner not only cleans the air, it helps to
stop ame if the engine backres. If it is not
there and the engine backres, you could be
burned. Do not drive with it off, and be careful
working on the engine with the air
cleaner/lter off.
Notice:If the air cleaner/lter is off, a backre can
cause a damaging engine re. And, dirt can
easily get into your engine, which will damage it.
Always have the air cleaner/lter in place when you
are driving.

Automatic Transaxle Fluid
When to Check and Change
A good time to check your automatic transaxle uid
level is when the engine oil is changed.
Change both the uid and lter every 50,000 miles
(83 000 km) if the vehicle is mainly driven under one or
more of these conditions:
In heavy city traffic where the outside temperature
regularly reaches 90°F (32°C) or higher.
In hilly or mountainous terrain.
When doing frequent trailer towing.
Uses such as found in taxi, police or delivery
service.
If you do not use your vehicle under any of these
conditions, change the uid and lter at 100,000 miles
(166 000 km).
SeePart A: Scheduled Maintenance Services on
page 6-4.
How to Check
Because this operation can be a little difficult, you may
choose to have this done at the dealership service
department.
If you do it yourself, be sure to follow all the instructions
here, or you could get a false reading on the dipstick.
Notice:Too much or too little uid can damage the
transaxle. Too much can mean that some of the uid
could come out and fall on hot engine or exhaust
system parts, starting a re. Too little uid could
cause the transaxle to overheat. Be sure to get an
accurate reading if you check the transaxle uid.
Wait at least 30 minutes before checking the transaxle
uid level if you have been driving:
When outside temperatures are above 90°F (32°C).
At high speed for quite a while.
In heavy traffic — especially in hot weather.
While pulling a trailer.

7. Remove any rust or dirt
from the wheel bolts,
mounting surfaces
and spare wheel.
{CAUTION:
Rust or dirt on the wheel, or on the parts to
which it is fastened, can make the wheel nuts
become loose after a time. The wheel could
come off and cause an accident. When you
change a wheel, remove any rust or dirt from
the places where the wheel attaches to the
vehicle. In an emergency, you can use a cloth
or a paper towel to do this; but be sure to use
a scraper or wire brush later, if you need to, to
get all the rust or dirt off.
{CAUTION:
Never use oil or grease on studs or nuts. If
you do, the nuts might come loose. Your wheel
could fall off, causing a serious accident.
8. Place the compact spare tire on the wheel-mounting
surface.
9. Then reinstall the
wheel nuts with the
rounded end of
the nuts toward the
wheel.
Make sure each wheel bolt is centered in each wheel
hole while tightening the nuts. Tighten each nut by
hand until the wheel is held against the hub.
