Mercedes-Benz 260 E 124 1988 Owner's Manual page 69

Charge Indicator Lamp
Should the charge indicator lamp fail
to come on prior to starting when the
key is in steering lock position
should it fail to go out after starting or
during operation, this indicates a fault
which must be repaired at an author­
ized MERCEDES-BENZ dealer as
soon as possible.
If the charge indicator lamp comes on
while the engine is running, this may
indicate that the poly-V-belt has bro­
ken. 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.
Low Engine Oil Level Indicator
Lamp
The indicator lamp comes on with the
or
key in steering lock position
2
should go out when the engine is
running.
If the indicator 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. Wenn this
occurs, the indicator 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 (see
page 74).
In addition to the indicator 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 74).
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.
Exterior Light Failure Indicator
Lamp
The light failure indicator comes on
and with the key in steering lock position
2
and should go out when the engine
starts.
If it comes on with the engine running,
it indicates a light failure.
If an exterior light fails, the indicator
will come on only when that light is
switched on.
If a brake or turn signal light fails, the
light failure indicator will come on
when applying the brake or actuating
the turn signal and stay on until the
engine is turned off.
Caution!
If additional lighting equipment is in­
stalled (e.g. auxiliary headlamps etc.)
be certain to connect into the fuse
before the failure indicator monitoring
unit in order to avoid damaging the
system.
