Coolant temperature
A warning lamp will come on if the coolant,
and therefore the engine, becomes too hot.
In addition, a message will appear on the
Control Display.
Check coolant level, refer to page226.
Engine oil temperature*
When the engine is at normal operating temper-
ature, the engine oil temperature is between
approx. 2107/1006 and approx. 3007/
1506.
If the engine oil temperature is too high, a mes-
sage appears on the Control Display.
Fuel gauge
Fuel tank capacity: approx. 16.1 gallons/
61 liters.
You can find information on refueling on
page207.
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
Once the fuel level has fallen to the reserve
zone, a message briefly appears on the Control
Display and the cruising range for the remaining
amount of fuel is displayed on the computer.
Under a cruising range of approx. 30 miles/
50 km, the message remains in 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.<
