Charge Indicator Lamp; Low Engine Oil Level Warning; Lamp - Mercedes-Benz 190 E 2.3 1991 Owner's Manual

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 autho­
rized MERCEDES-BENZ dealer im­
mediately.
If the charge indicator lamp comes on
while the engine is running, this may
indicate that the poly-V-belt has brok­
en. Should this condition occur, the
poly-V-belt must be replaced before
continuing to operate the vehicle.
Otherwise, the engine will overheat
due to an inoperative water pump
which may result in damage to the
engine.
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.
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 speeds results in
increased consumption.

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 engine is
running.
If the warning lamp comes on with
the engine running and at operating
temperature, the engine oil level has
dropped to approximately the mini­
mum 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, continue to drive
to the nearest service station where
the engine oil should be topped to the
"full" mark of the dipstick (page 78).
In addition to the warning lamp, the
engine oil level should be periodically
checked with the dipstick, for example
during a fuel stop, or before a long trip
(see page 78).
