Engine Oil Life System
When to Change Engine Oil
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 message will come
on. SeeDIC Warnings and Messages on page 3-69.
Change your oil as soon as possible within the next
600 miles (1 000 km). 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 Engine Oil Life
System
The Engine 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 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.
3. Turn the key to OFF.
5-18

If the CHANGE OIL 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.
Supercharger Oil
Unless you are technically qualied and have the proper
tools, you should let your dealer perform this
maintenance.
SeeEngine 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. See
Recommended Fluids and Lubricants on page 6-12.
5-19

How to Check and Add Oil
{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.
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.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.
SeeEngine Compartment Overview on page 5-12for
more information on location.
When to Inspect the Engine
Air Cleaner/Filter
Inspect the air cleaner/lter at the MaintenanceII
intervals and replace at the rst oil change after
50,000 miles (83 000 km). SeeScheduled Maintenance
on page 6-4for more information. If you are driving
in dusty/dirty conditions, inspect the lter at each engine
oil change.
5-20

Automatic Transaxle Fluid
When to Check and Change
A good time to check the 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 the vehicle is not used under any of these
conditions, change the uid and lter at
100,000 miles (166 000 km).
SeeScheduled Maintenance 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.
To get the right reading, the uid should be at normal
operating temperature, which is 180°F to 200°F
(82°C to 93°C).
Get the vehicle warmed up by driving about
15 miles (24 km) when outside temperatures are
above 50°F (10°C). If it is colder than 50°F (10°C),
you may have to drive longer.
