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 imme-
diately.
If the charge indicator lamp comes
on while the engine is running,
this may indicate that the poly-V-
belt has broken. Should this
condition occur, the poly-V-belt
must be replaced before con-
tinuing to operate the vehicle.
Otherwise, the engine will over-
heat due to an inoperative water
pump which may result in damage
to the engine.
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. Frequent driving at high
engine speeds results in increased
consumption.
Engine Oil Pressure Gauge
The oil pressure at idle speed may
drop to 4.4 psi (0.3 bar) if the en-
gine is at operating temperature.
This will not jeopardize its opera-
tional reliability.
Pressure must, however, rise
immediately upon acceleration.
Low Engine Oil Level Warning
Lamp
The warning lamp comes on with
the key in steering lock position 2
and should go out when the en-
gine is running.
If the warning lamp comes on with
the engine running and at opera-
ting temperature, the engine oil
level has dropped to approxima-
tely the minimum mark on the
dipstick. When this occurs, the
warning lamp will first come on
intermittently and then stay on if
the oil level drops further. If no oil
leaks are noted and there is no
loss in engine oil pressure, con-
tinue to drive to the nearest ser-
vice station where the engine oil
should be topped to the “full”
mark of the dipstick (see Index).
In addition to the warning lamp,
the engine oil level should be
periodically checked with the dip-
stick, for example during a fuel
stop, or before a long trip (see
Index).
