Possible cause:
The fuel tank contains no more

Refuelling ( 93).
Range
z
The range readout 1
dicates how far you can ride with
the fuel remaining in the tank.
This distance is calculated on the
basis of average consumption
and the quantity of fuel on board.
RANGE
When the motorcycle is
propped on its side stand
the slight angle of inclination
means that the sensor cannot
register the fuel level correctly.
This is the reason why the
range is calculated only
when the side stand is in the
retracted position.
The range reading appears
automatically on the multifunc-
tion display when fuel is down
to the reserve level.
After a refuelling stop, range is
recalculated if the amount of
fuel in the tank is greater than
the reserve quantity.

NOTICE
The calculated range is only
an approximate figure. Con-
sequently, BMW Motorrad re-
commends that you should not
try to use the full range before
refuelling.
