5-22 Instruments and Controls
Average Fuel Economy
This display shows the
approximate average liters per
100 kilometers (L/100 km) or miles
per gallon (mpg). This number is
calculated based on the number
of L/100 km (mpg) recorded since
the last time this menu item was
reset. The fuel economy can be
reset by pressing SET/CLR while
the Average Fuel Economy display
is showing. The display may not
reset to zero.
Instantaneous Fuel Economy
This display shows the current
fuel economy in either liters per
100 kilometers (L/100 km) or miles
per gallon (mpg). This number
reflects only the fuel economy
that the vehicle has right now and
changes frequently as driving
conditions change. Unlike average
economy, this display cannot be
reset.
Average Vehicle Speed
This display shows the average
speed of the vehicle in kilometers
per hour (km/h) or miles per
hour (mph). This average is
calculated based on the various
vehicle speeds recorded since the
last reset of this value. The average
speed can be reset by pressing
SET/CLR while the Average Vehicle
Speed display is showing.
Timer
This display can be used as a timer.
To start the timer, press SET/CLR
while Timer is displayed. The
display will show the amount of time
that has passed since the timer was
last reset, not including time the
ignition is off. Time will continue to
be counted as long as the ignition is
on, even if another display is being
shown on the DIC. The timer will
record up to 99 hours, 59 minutes
and 59 seconds (99:59:59) after
which the display will return to zero.
To stop the timer, press SET/CLR
briefly while Timer is displayed. To
reset the timer to zero, press and
hold SET/CLR.
Digital Speedometer
The speedometer shows how fast
the vehicle is moving in either
kilometers per hour (km/h) or miles
per hour (mph). The speedometer
cannot be reset.

or Navigation System Turn-by-Turn
guidance. See The OnStar Owner's
Guide or the Navigation manual,
if the vehicle has navigation, for
more information.
