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
immediately.
If the charge indicator lamp comes
on while the engine is running,
this may indicate that the poly-V-
belt has broken. Should this con­
dition 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.

Engine Oil Pressure Gauge with
Oil Pressure Warning Lamp
With the key in steering lock
position 2, the oil pressure warn­
ing lamp comes on and should go
out when the engine is running.
The oil pressure at idle speed may
drop if the engine is at operating
temperature. This will not jeo­
pardize the engine's operational
reliability.
Pressure must, however, rise
immediately upon acceleration.
Note:
If the oil pressure warning lamp
does not go out after starting the
engine or comes on while driving
and the oil pressure gauge needle
drops to " 0 " , then damage to the
engine may occur with continued
operation. Turn off engine imme­
diately and contact an authorized
Mercedes-Benz dealer. Do not
operate the car until the condition
is repaired.
There is no need for concern
should the oil pressure warning
lamp light up briefly, (for example,
in sharp turns or hard braking)
provided the lamp goes out
immediately. We recommend you
to drive to the nearest service
station where the engine oil
should be topped to the ''full"
mark on the dipstick with an
approved oil.
