CHANGE ENGINE OIL ± 82:This means that the life
of the engine oil has expired and it should be changed
within 200 miles. After an oil change, the Oil Life
Indicator must be reset. See
Oil Life Indicator on
page 3-77. SeeEngine Oil on page 5-13.
CHANGE TRANS FLUID ± 47:This message will
appear when it is time to change the transaxle ¯uid. See
Part A: Scheduled Maintenance Services on page 6-4for the proper ¯uid and change intervals.
CHECK BRAKE FLUID ± 37:This message will
display if the ignition is in ON to inform the driver that
the brake ¯uid level is low. Have the brake system
serviced by a technician as soon as possible. See
Brake
System Warning and Parking Brake Indicator Light on
page 3-43
.
CHECK COOLANT LEVEL ± 2:This message will
appear when there is a low level of engine coolant. Have
the cooling system serviced by a technician as soon
as possible. See
Engine Coolant on page 5-25.CHECK FUEL GAGE ± 50:This message will appear

CHECK OIL LEVEL ± 36:For correct operation of the
low oil sensing system, your vehicle should be on a
level surface. A false CHECK OIL LEVEL message may
appear if the vehicle is parked on a grade. The oil
level sensing system does not check for actual oil level
if the engine has been off for a short period of time,
and the oil level is never checked while the engine is
running. If the CHECK OIL LEVEL message appears,
and your vehicle has been parked on level ground
with the engine off for at least 30 minutes, the oil level
should be checked by observing the oil dipstick. Prior to
checking the oil level, be sure the engine has been
off for a few minutes and your vehicle is on a level
surface. Then check the dipstick and add oil if
necessary. See
Engine Oil on page 5-13.

Trip Computer
Oil Life Indicator
This feature lets you know when to change the engine
oil. It's based on the engine oil temperatures and
your driving patterns.To see the display, press the INFO button several times
until ENGINE OIL LIFE appears. If you see 99%
ENGINE OIL LIFE, 99 percent of your current oil life
remains.
The DIC may display a CHANGE ENGINE OIL
message. For more information, see
Scheduled
Maintenance on page 6-4. If you see CHANGE ENGINE
OIL, it means the oil life is gone and you should
change the oil right away. The system doesn't check
how much oil you have, so you'll still have to check for
that. To see how, see
Engine Oil on page 5-13.
When the oil is changed, you'll need to reset the system.
See
Engine Oil on page 5-13. Always keep a written
record of the mileage and date when you changed
your oil.

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.
5-16

As in the chart shown previously, 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.
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 in the
Driver Information Center (DIC) 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.
5-17

How to Reset the CHANGE ENGINE OIL
Message
The GM Oil Life SystemŸ 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 in the Driver
Information Center (DIC) being turned on, reset
the system.
After the oil has been changed, the CHANGE ENGINE
OIL message must be reset. To reset the message,
do the following:
1. Turn the key to the ªONº position without starting
the engine.
2. Press the INFO button on the Driver Information
Center (DIC) until ENGINE OIL LIFE is displayed.
3. Press and hold the INFO RESET button until 100%
ENGINE OIL LIFE is displayed. This resets the oil
life indicator.
The percentage of oil life remaining may be checked at
any time by pressing the INFO button until ENGINE
OIL LIFE is displayed on the DIC. For more information
on the oil life indicator, see
Oil Life Indicator on
page 3-77.
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.
