General information regarding the on-
board computer functions 
Range on remaining fuel 
The range on remaining fuel is continuously re-
computed while driving based on fuel level, cur-
rent consumption and average consumption.
The more the fuel level falls, the more spontane-
ously the display reacts. For this reason, range on 
remaining fuel is not displayed if less than 15 kilo-
meters (9 miles). 
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 add only a small 
quantity of fuel, this cannot be used to calculate 
the range on remaining fuel. 
Average consumption and average speed 
The displayed values 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 mea-
surements. Values can thus be collected over long 
periods.
Disconnecting the car battery clears these memo-
ries. 
Outside temperature 
The outside temperature display does not indi-
cate, if ice is on the road. 
Even if a temperature above 32°F (0°C) is dis-
played, ice may still form on the road, for instance 
on bridges or when the road passes through a 
heavily shaded area. 
Tire pressure
The function of the on-board computer Tire 
pressure 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 “Pressure info” display in the Tire 
pressure menu.
