Engine oil thermometer
The general operating temperature lies
between 1757/806 and 2507/1206. Do
not exceed a value of approx. 2657/1306.
If the engine oil temperature is too high, the per-
missible engine speed, and with it the available
engine output is reduced.
Fuel gauge
Fuel tank capacity: approx. 18.5 gallons/
70 liters. You will find information on refueling
on page174.
If the tilt of the vehicle varies for a longer period,
when you are driving in mountainous areas, for
example, the indicator may fluctuate slightly.
Reserve
After the reserve quantity has been reached, a
message briefly appears on the Control Display;
the remaining range is shown in the computer.
Below a range of approx. 30 miles/50 km, the
message remains on the Control Display.Refuel as soon as possible once your
cruising range falls below 30 miles/
50 km, otherwise engine functions are not
ensured and damage can occur.<

Outside temperature
If the display drops to +377/+36, a signal
sounds and a warning lamp lights up. A mes-
sage appears on the Control Display. There is
an increased danger of ice.
Even at temperatures above +377/
+36 ice can form. Therefore, drive care-
fully, e.g. on bridges and sections of road in the
shade, otherwise there is an increased accident
risk.<
