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.
Econom ical D riving Indicator
(ECONOMY)
The indicator shows the fuel consump­
tion tendency during various driving
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 frequently
in the red area.
Engine Oil Consumption
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.
When the charging indicator lamp
glows while the engine is running, the
V-belt may have been broken (which
also makes the water pump inopera­
tive). This may cause overheating and
damage to the engine. In this case the
V-belt must be replaced at once.
Deceleration Shutoff
The fuel injection process is interrupted
only during deceleration, if the driver’s
foot is fully removed from the gas
pedal.
Charge Indicator Lamp
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 immedi­
ately upon acceleration.
Engine Oil Temperature Indicator
The normal engine oil operating
temperature range is between 80° C to
120° C (176° F to 248° F).
The engine oil temperature may, under
certain conditions, rise to 150° C
(302° F) maximum. If this temperature
is exceeded, we recommend that you
check the oil level. It should not be
above the upper mark (max) on the
dipstick.
