Between the blue and red zones
Normal operating range. The needle
may rise as far as the edge of the red
sector during normal operation.
Once the indicator lamp stays on con-
tinuously, there are still approx.
2 gallons/8 liters of fuel in the fuel tank.
Blue
The engine is still cold. Drive at moder-
ate engine and vehicle speeds.
Fuel tank capacity approx. 16.6 gal./
63 liters.
Red
If the tilt of the vehicle varies – when
you are driving in mountainous areas,
for example – the needle may fluctuate
slightly.
When you switch on the ignition, the
warning lamp comes on briefly as an
operation check.
If the lamp comes on while operating
the vehicle: the engine has overheated.
Switch off the engine immediately and
allow it to cool down.
Fill the fuel tank before it is com-
pletely empty. Driving to the last
drop of fuel can prevent the engine
from operating properly and result in
damage.<

When you switch on the ignition, the
