Indicator and warning
lamps
Technology that monitors itself
The indicator and warning lamps identified
by the
+ symbol are subjected to an oper-
ation check each time you switch on the
ignition or start the engine. They each light
up once for different periods of time.
When a malfunction occurs in a monitored
system, the corresponding lamp will either
fail to go out when the engine is started, or
it will come on again during normal driving,
usually accompanied by a Check Control
message. You will find more details on the
specified pages.
Fixed indicator and warning lampsColors The indicator and warning lamps can light
up in different colors and combinations.
>Red:
Stop immediately
or
important reminder
>Red and yellow:
Continue to drive; drive cautiously
>Yellow:
Have the system checked at the earliest
opportunity
or
for your information
>Green or blue:

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
message appears on the Control Display.
Fuel gauge
Fuel tank capacity: approx. 18.5 US gal-
lons/70 liters, including the reserve capac-
ity of approx. 2.1 gallons/8 liters. You can
find information on refueling on page 162.
If the tilt of the vehicle varies for a longer
period, when you are driving in mountain-
ous areas, for example, the indicator may
fluctuate slightly.
After the reserve quantity has been
reached, a message appears for a short
time on the Control Display; the remaining
range is shown in the computer. Below a
range of approx. 30 miles/50 km, the mes-
sage 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.<
