Safe Driving
Charge Indicator Lamp
Should the charge indicator lamp
fail to come on prior to starting when
the ignition key is in position "2" or
should it fail to go out after starting
or during operation, this indicates a
fault which must be repaired at a
MERCEDES-BENZ service station as
soon as possible.
Oil Pressure Gauge
The oil pressure may drop at idle
speed to 0.5 bar/7.1 psi if the engine
is at operating temperature. This will
not jeopardize its operational reliabi
lity. Pressure must, however, rise
immediately upon acceleration.
The oil pressure gauge does not
provide any information concerning
the oil level in the engine.
Coolant Temperature Gauge
Due to the pressurized cooling
system, the coolant only starts
boiling at a temperature of approx.
125° C/257° F with a antifreeze-
blended coolant fill protecting down
to -30° C /-22° F (see also "Fuels,
Coolants, Lubricants, etc.").
During severe operating conditions
and stop-and-go city traffic, the
coolant temperature must not rise
above the red marking.
Engine Oil Consumption
Engine oil consumption can only be
determined after a certain mileage
has been covered. During the
break-in period, higher oil consump
tion may be noticed and is normal.
Frequent high engine speed opera
tion will also cause increased oil
consumption.
Emission Control
Certain systems of the engine serve
to keep the toxic components of the
exhaust gases within permissible
limits required by law. (Nevertheless,
we urgently advise you not to let the
engine run in a closed garage.)
These systems, of course, will func
tion properly only when maintained
strictly according to factory specifi
cations. Any adustments on the
engine should, therefore, be carried
out only by qualified MERCEDES-
BENZ technicians. The adjustments
of the engine should not be altered
in any way. Moreover, the specified
service and maintenance jobs must
be carried out regularly according to
MERCEDES-BENZ servicing require
ments. For details refer to Mainten
ance Booklet.
