an average of recent driving conditions.
As your
driving conditions change, this data is gradually updated.
Fuel range cannot be reset.
Average Fuel Economy
Press the fuel information button until AVG appears in
the display. Average fuel economy is how many
miles per gallon your vehicle is getting based on current

So, be
sure to check your oil level often. See
Engine Oil on
page 5-13.

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 identified as
SAE 5W-30.
If you cannot find such SAE 5W-30 oils,
you can use an SAE IOW-30 oil which has the API
Starburst symbol,
if it's going to be 0°F (-18°C)
or above. Do not use other viscosity grade oils, such as
SAE IOW-40 or SAE 20W-50 under any conditions.
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 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 OW-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 YO
when to change the engine oil-and filter. This is
IU know
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 ENG OIL light 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 filter must be changed
at least once a year and at this time the system must be
reset. 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 CHANGE ENG OIL Light
The GM Oil Life System calculates when to change
your engine oil and filter 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 ENG OIL light being turned on, reset the
system.
To reset the CHANGE ENG OIL light, do the following:
1. Turn the ignition key to RUN with the

times within five seconds.
For vehicles with the Driver Information Center, see
Driver Information Center (DE) on page 3-43 to reset
the system.
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
filter 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 CleanedFilter
The engine air cleanedfilter
is located toward the front
of the engine compartment
on the passenger’s side
of the vehicle.

Engine Oil Scheduled Maintenance
Change engine oil and filter as indicated by the GM
Oil Life System (or every 12 months, whichever
occurs first). Reset the system.
Your vehicle has a computer system that lets you know
when
to change the engine oil and filter. 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 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 filter must be
changed at least once a year and at this time the system
must be reset.
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. See
Engine Oil on
page 5-13 for information on resetting the system.
After the services are performed, record the date, odometer reading and who performed the service on the
maintenance record pages in Part
E of this schedule.
