Setting the Compass
The compass is self-calibrating, which eliminates the
need to manually set the compass.
However, under certain circumstances, such as during a
long distance cross-country trip, it will be necessary
to compensate for compass variance and reset the zone
through the DIC.
Compass variance is the difference between earth's
magnetic north and true geographic north. If not
adjusted to account for compass variance, the compass
in your vehicle could give you false readings.
In order to do this, you will have to set or calibrate the
compass to the variance zone in which you are located.

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 OIL SOON light 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 GM 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 a
CHANGE OIL SOON message appearing on the DIC,
reset the system.
To reset the GM Oil Life System, after the oil has been
changed, use the following procedure:
1. Press the options button on the DIC until ENGINE
OIL MONITOR appears on the DIC screen.
2. Press the set/reset button to reset the system.
The next screen indicates that the engine oil monitor
system has been reset.
If the vehicle is equipped with the trip computer DIC,
when the gage button is pressed and the OIL LIFE
REMAINING mode appears, it should read 100 percent
OIL LIFE REMAINING.

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.
Supercharger Oil
Unless you are technically
quali®ed and have the
proper tools, you should let
your dealer or a quali®ed
service center perform
this maintenance.
See
Engine Compartment Overview on page 5-12for
the Supercharger Oil ®ll location.
When to Check
Check oil level every 30,000 miles (50 000 km) or every
36 months, whichever occurs ®rst.
What Kind of Oil to Use
Use only the recommended supercharger oil. SeePart D:
Recommended Fluids and Lubricants on page 6-16.
5-21

How to Check and Add Oil
Park the vehicle on a level surface. 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 ®ll plug
while the engine is hot, pressure may cause
hot oil to blow out of the oil ®ll hole. You may
be burned. Do not remove the plug until the
engine cools.
1. Clean the area around the oil ®ll plug before
removing it.
2. Remove the oil ®ll plug.
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.
Tighten to 88 lb-in (10Y).
Engine Air Cleaner/Filter
The engine air cleaner/®lter is located in the engine
compartment on the driver's side of the vehicle.
See
Engine Compartment Overview on page 5-12for
more information on location.
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 engine 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 ªcakedº with dirt,
a new ®lter is required.

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 90ÉF (32ÉC) 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).
See
Part 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
your 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 your
transaxle ¯uid.
Wait at least 30 minutes before checking the transaxle
¯uid level if you have been driving:
·When outside temperatures are above 90ÉF (32ÉC).
·At high speed for quite a while.
·In heavy traffic ± especially in hot weather.
·While pulling a trailer.
