General information regarding the
on-board computer functions
Range on remaining fuel
The range on remaining fuel is continuously recal-
culated during the journey based on the fuel level,
current consumption and average consumption.
The more the fuel level falls, the more spontan-
eously the display reacts. For this reason, the
range on remaining fuel is not displayed if less
than 9 miles (15 kilometers).
If the vehicle's inclination changes while driving or
refuelling, incorrect range information may tempo-
rarily be given.
Note
If the tank is nearly empty and you top up with only
a small quantity of fuel, an accurate range on re-
maining fuel is impossible.
Average consumption and average speed
The values displayed are based on the distance
travelled since the last reset to "zero".
You can set the starting time for a measurement
before or during the trip.
Switching the ignition off does not reset the meas-
urements. It is therefore possible to collect values
over long periods.
Disconnecting the car battery will cause these
memories to be erased.
Tire pressure
The Tire pressure function of the on-board com-
puter displays the tire pressures dependent on
temperature in the four wheels. You can watch the
tire pressure rise and fall while driving.
The display is only for information. To correct the
tire pressures, always use the displayed values
from the "Info pressure" display in the Tire pres-
sure menu.
