Charge Indicator Lamp; Pressure Warning Lamp - Mercedes-Benz 300 SL 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 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 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 with
Oil Pressure Warning Lamp
With the key in steering lock position
2, the oil pressure warning lamp comes
on and goes out with the engine
running.
The oil pressure at idle speed may drop
if the engine is at operating
temperature. This will not jeopardize
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 immediately 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.
