Charge Indicator Lamp - Mercedes-Benz 500 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.
Do not continue to drive the vehicle
with the charge indicator lamp
illuminated. Doing so could result in
engine damage that is not covered by
the Mercedes-Benz Limited Warranty.
Engine Oil Temperature Gauge
Normal operating engine oil
temperatures are from 175°F
0
(80 C) to 250°F(120°C),
During severe operating conditions and
stop-and-go traffic, the engine oil
temperature may rise close to the red
marking.
The engine should not be operated with
the engine oil temperature in the red
zone. Doing so may cause serious
engine damage which is not covered by
the Mercedes-Benz Limited Warranty.
When the engine oil temperature is
close to the red marking, relieve the
load on the engine by decreasing
vehicle speed to lower engine oil
temperature.
Once the engine oil temperature returns
to the normal temperature range, the
engine oil level should be checked. See
Engine oil level, checking in Index.
Low Engine Oil Level Warning
Lamp
With the key in steering lock position
2, the oil pressure warning lamp comes
on and goes out with the engine
running.
If the warning lamp comes on with the
engine running and at operating
temperature, the engine oil level has
dropped to approximately 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
indicated engine oil pressure, continue
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.
The low engine oil level warning light
should not be ignored. Extended
driving with the light illuminated could
result in engine damage that is not
covered by the Mercedes-Benz
Limited Warranty.
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.
