Engine Oil Consumption
Engine oil consumption can only be
determined after a certain mileage
has been covered. During the break-
in period, higher oil consumption may
be noticed and is normal.
Economical Driving Indicator
(ECONOMY)
The indicator shows the fuel con­
sumption tendency during various dri­
ving modes.
High fuel consumption is indicated if
the pointer moves into the red area;
economical driving is indicated when
it is in the black area. The indications
should only be compared within the
same gear.
Do not compare fuel consumption
readings between different gears. The
following rule applies: If you drive at
equal speeds, the fuel consumption is
lower in the higher gear, although in
this gear the pointer is more frequent­
ly in the red area.
Charge Indicator Lamp
Should the charge indicator lamp
fail to come on prior to starting when
the key is in steering lock position
2 or should it fail to go out after
starting or during operation, this
indicates a fault which must be
repaired at an authorized
MERCEDES-BENZ dealer as soon
as possible.
Oil Pressure Gauge
The oil pressure at idle speed may
drop to 0.3 bar (4.4 psi) if the engine
is at operating temperature. This
will not jeopardize its operational
reliability.
Pressure must, however, rise imme­
diately upon acceleration.
Low Engine Oil Level Indicator
Lamp
The indicator lamp comes on with the
key in steering lock position 2 and
should go out when the engine is run­
ning.
If the indicator lamp comes on with
the engine running and at operating
temperature, the oil level has dropped
to the minimum mark on the dipstick.
When this occurs, the indicator lamp
will first come on intermittently and
then stay on if the oil level drops fur­
ther. Engine oil should be added at
the next opportunity (we recommend
that you add 1 liter [1.1 US qt]).
In addition to the indicator lamp, the
engine oil level should be periodically
checked with the dipstick, for exam­
ple after a fuel stop, or before a long
trip (see page 71).
