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 serious engine damage that is
not covered by the Mercedes-Benz
Limited Warranty.

Engine Oil Pressure Gauge

The oil pressure at idle speed may
drop if the engine is at operating
temperature. This will not jeop­
ardize the engine's operational
reliability.
Pressure must, however, rise
immediately upon acceleration.
Note:
If the oil pressure gauge needle
drops to "0" with the engine
running, 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.
