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 CHANGE ENGINE OIL
Message
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 ENGINE OIL message being turned on, reset
the system.To reset the CHANGE ENGINE OIL message, see ªGM
Oil Life Systemº under
DIC Operation and Displays
on page 3-51for vehicles equipped with the DIC, or do
the following:
1. Turn the ignition key to RUN with the engine off.
2. Fully press and release the accelerator pedal three
times within ®ve seconds.
If the OIL LIFE RESET message ¯ashes for 10 seconds,
the system is reset.
If the system does not reset, try the procedure once
again. If it still does not reset, see your dealer for service.
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.

Windshield Washer Fluid
What to Use
When you need windshield washer ¯uid, be sure to read
the manufacturer's instructions before use. If you will be
operating your vehicle in an area where the temperature
may fall below freezing, use a ¯uid that has sufficient
protection against freezing. See
Engine Compartment
Overview on page 5-12for reservoir location.
Adding Washer Fluid
Your vehicle has a low washer ¯uid message that
comes on when the washer ¯uid is low. The message is
displayed for 15 seconds at the start of each ignition
cycle. When the LOW WASHER FLUID message
is displayed, you will need to add washer ¯uid to the
windshield washer ¯uid reservoir.
The windshield washer
¯uid reservoir is located in
the engine compartment
toward the front of the
vehicle on the driver's side.
Open the cap with the washer symbol on it. Add washer
¯uid until the tank is full.
Notice:
·When using concentrated washer ¯uid, follow
the manufacturer's instructions for adding
water.
·Don't mix water with ready-to-use washer ¯uid.
Water can cause the solution to freeze and
damage your washer ¯uid tank and other parts
of the washer system. Also, water doesn't
clean as well as washer ¯uid.
·Fill your washer ¯uid tank only three-quarters
full when it's very cold. This allows for
expansion if freezing occurs, which could
damage the tank if it is completely full.
·Don't use engine coolant (antifreeze) in your
windshield washer. It can damage your
washer system and paint.

damaged. The repairs wouldn't be covered by
your warranty.
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter or accessory power outlets. Turn off the
radio and all lamps that aren't needed. This
will avoid sparks and help save both batteries. And
it could save your radio!
4. Open the hoods and locate the positive (+) and
negative (-) terminal locations of the other vehicle.
Your vehicle has a remote positive (+) jump
starting terminal and a remote negative (-) jump
starting terminal. You should always use these
remote terminals instead of the terminals on the
battery.The remote positive (+)
terminal is located under a
red plastic cover near
the engine accessory drive
bracket. To access the
remote positive (+)
terminal, open the red
plastic cover.
