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 CHG OIL message in the
message center will come on. SeeChange Engine
Oil Message on page 183for more information
on this message. Change the 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, the engine oil and lter must be changed
at least once a year and at this time the system
must be reset. Your retailer has trained service
people who will perform this work using genuine
Saturn parts and reset the system. It is also
important to check the oil regularly and keep it at
the proper level.
If the system is ever reset accidentally, you must
change the 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 the engine oil and lter based on vehicle
use. Anytime the oil is changed, reset the
system so it can calculate when the next oil
change is required. If a situation occurs where you
change the oil prior to the CHG OIL message
being turned on, reset the system.

After changing the engine oil, reset the system by
doing the following:
1. Press and release the trip/reset button until
the OIL LIFE message is displayed.
2. Then press and hold the trip/reset button until
a chime sounds ve times, and RESET is
displayed in the message center.
When the system is reset, the odometer will
again be displayed in the message center.
3. Turn the ignition key to LOCK.
If the CHG OIL message comes back on when
you start your vehicle, the engine oil life system
has not reset. Repeat the procedure.
Your vehicle has a unique oil lter element. When
installing the ller cap do not exceed 18 lb-ft
(25
Y). Inspect the condition of the O-ring and
replace if damaged. See your Saturn retailer
for additional information.
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 used oil, ask your retailer,
a service station or a local recycling center
for help.

Headlamp Aiming
Headlamp aim has been preset at the factory and
should need no further adjustment.
If your vehicle is damaged in an accident, the
headlamp aim may be affected. Aim adjustment to
the low-beam headlamps may be necessary if it
is difficult to see the lane markers (for horizontal
aim), or if oncoming drivers ash their high-beam
headlamps at you (for vertical aim). If you
believe your headlamps need to be re-aimed, we
recommend that you take your vehicle to your
retailer for service.

center comes on, it means that service is required
for your vehicle. SeeChange Engine Oil

system may not indicate that vehicle service 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 Saturn retailer has Saturn-trained service
technicians who will perform this work using
genuine Saturn parts and reset the system.If the engine oil life system is ever reset
accidentally, you must service your vehicle within

System and resetting the system.

services, checks, and inspections are required.

required more often.
