Trip Computer
The vehicle may have a trip
computer. The trip computer
provides information on driving
data. This information is continually
recorded and evaluated
electronically. If power has been
interrupted or if the battery voltage
has dropped too low, the values
stored in the trip computer will
be lost.
To access trip computer vehicle
data, do one of the following:
Press the BC button on the audio
system.
Press the left thumbwheel, if your
vehicle has this feature, on the
steering wheel.
Once an audio function has been
selected, the rows of the trip
computer function are displayed.The functions are displayed in the
following order:

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

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.
