Average fuel consumption
If you continue to press the button on the
turn signal lever, the average fuel con-
sumption last displayed is recalculated
from that point in time.
Any time spent when the vehicle is station-
ary and the engine shut off is ignored in the
calculation.
Cruising range
The computer bases its calculations of the
cruising range on the preceding driving
style and on the remaining fuel in the tank.
It is important that you refuel when
the cruising range falls below approx.
30 miles/50 km. Otherwise, the engine
cannot be guaranteed to operate properly
and damage may result.
