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
refueling, 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.
