Boost Gage
If your vehicle is equipped with this gage, it is located
on the steering column.
This gage indicates vacuum during light to moderate
throttle and boost under heavier throttle.
This gage displays the air pressure level in the intake
manifold before it enters the engine’s combustion
chamber.
This gage is automatically centered at zero every time
the ignition is turned to RUN. Actual vacuum or boost
is displayed from this zero point.The boost gage is also equipped with three pairs of
lights that are located on each side of the gage. These
lights are used to indicate three different engine rpm
levels. The default setting for the lower pair of lights is
4,400 rpm, the middle pair of lights is 5,600 rpm, and the
top pair of lights is 6,200 rpm. These settings can be
adjusted by turning the stem behind each light. To have
the light pair come on at a higher rpm level, turn the stem
counterclockwise. To have the light pair come on at a
lower rpm level, turn the stem clockwise. Each turn
adjusts the settings by 100 rpm. To restore the default
settings, press and hold any stem for three seconds.
The lights will ash three times.
To turn the lights off or on, press and release any stem.Message Center
The message center is located in the instrument
panel cluster. It gives you important safety and
maintenance facts.
If there are several messages, each message will be
shown for a few seconds and will continue to repeat until
cleared. To clear a message, press the trip/reset button
while the message you want to clear is being displayed.
Many messages will also cause a chime to sound, to
alert you to the message. United States

Scheduled Maintenance
When the CHG OIL message in the message center
comes on, it means that service is required for
your vehicle. SeeChange Engine Oil Message on
page 3-45. Have your vehicle serviced 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 engine oil life 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 3,000 miles
(5 000 km) since your last service. Remember to reset
the oil life system whenever the oil is changed. See
Engine Oil Life System on page 5-20for information on
the Engine Oil Life System and resetting the system.When the CHG OIL message appears, certain
services, checks, and inspections are required.
Required services are described in the following for
“MaintenanceI” and “MaintenanceII.” Generally, it is
recommended that your rst service be MaintenanceI,
your second service be MaintenanceII, and that you
alternate MaintenanceIand MaintenanceIIthereafter.
However, in some cases, MaintenanceIImay be
required more often.
MaintenanceI— Use MaintenanceIif the CHG OIL
message comes on within 10 months since the
vehicle was purchased or MaintenanceIIwas
performed.
MaintenanceII— Use MaintenanceIIif the previous
service performed was MaintenanceI. Always use
MaintenanceIIwhenever the message comes on
10 months or more since the last service or if the
message has not come on at all for one year.
