economy at a particular moment
and will change frequently as driving
conditions change. This display
shows the instantaneous fuel
economy in miles per gallon (mpg) or
liters per 100 kilometers (l/100 km).
The metric display changes
depending on speed:
Below 8 mph (13 km/h), displays
in l/h.
Above 8 mph (13 km/h), displays
in l/100 km.
This screen cannot be reset.Average Consumption
This display shows the approximate
average miles per gallon (mpg) or
liters per 100 kilometers (l/100 km).
This number is calculated based
on the number of mpg (l/100 km)
recorded since the last time this
menu item was reset.
The measurement can be reset to
zero at any time and restarted.
See “Reset” later in this section.

less than 31 miles (50 km) can be
driven with the fuel remaining in
the tank.
SeeDIC Warnings and Messages
(Base and Uplevel Systems) on
page 4-37for information on

The fuel range estimate is based
on an average of the vehicle’s fuel
economy over recent driving history
and the amount of fuel remaining in
the fuel tank. This estimate will
change if driving conditions change.

For example, if driving in traffic and
making frequent stops, this display
may read one number, but if the
vehicle is driven on a freeway,
the number may change even
though the same amount of fuel
is in the fuel tank. This is because
different driving conditions produce
different fuel economies. Generally,
freeway driving produces better
fuel economy than city driving.
Fuel range cannot be reset.
Instantaneous Consumption
This display shows the current fuel
economy at a particular moment and
will change frequently as driving
conditions change. This display
shows the instantaneous fuel
economy in miles per gallon (mpg) or

The measurement can be reset to
zero at any time and restarted.
See “Reset” later in this section.Average Speed
This display shows the average
speed of the vehicle in miles per
hour (mph) or kilometers per
hour (km/h). This average is
calculated based on the various
vehicle speeds recorded since
the last reset of this value.
The measurement can be reset to
zero at any time and restarted.

Trip Consumption
This display shows the number
of gallons (gal) or liters (l) of
fuel used since the last reset.
The measurement can be reset to

Vehicle Data
Recording and
Privacy
Your Saturn vehicle has a number of
sophisticated computers that record
information about the vehicle’s
performance and how it is driven.
For example, your vehicle uses
computer modules to monitor and
control engine and transmission
performance, to monitor the
conditions for airbag deployment and
deploy airbags in a crash and, if so
equipped, to provide antilock braking
to help the driver control the vehicle.
These modules may store data to
help your dealer/retailer technician
service your vehicle. Some modules
may also store data about how you
operate the vehicle, such as rate of
fuel consumption or average speed.
These modules may also retain the
owner’s personal preferences, such
as radio pre-sets, seat positions, and
temperature settings.
