Engine oil thermometer
The engine oil temperature is between approx.
1607/706 and approx. 3407/1706 during
normal operation.
If the engine oil temperature is too high, a mes-
sage appears on the Control Display.
Fuel gage
Fuel tank capacity: approx. 18.5 US gallons/
70 liters, including the reserve capacity of
approx. 2.1 gallons/8 liters. You can find infor-
mation on refueling on page166.
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.
After the reserve quantity has been reached, a
message appears for a short time on the Con-
trol 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, as otherwise engine functions are not
ensured and damage can occur.<
Service requirements
The remaining distance to be driven and the
date for the next maintenance are briefly indi-
cated with the ignition key in position 2.
Your BMW Service Advisor will determine
your vehicle's current service require-
ments by reading out the data stored in the
