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.
Fuel Reserve Warning Lamp
The fuel reserve warning lamp will
come on when the key in the steer­
ing lock is turned to position “2” ,
and will go out after the engine is
running.
If the warning lamp stays on after
the engine starts, or comes on while
driving, it indicates that the fuel level
is down to the reserve quantity.
Oil Pressure Gauge
The oil pressure may drop at idle
speed to 0.3 bar/4.4 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 will not
provide early warning of low oil level.
Therefore, check oil level at regular
intervals with the dipstick.
Coolant Temperature Gauge
Due to the pressurized cooling
system, the coolant only starts
boiling at a temperature of approx.
125° C/257° F with an anti-corro-
sion/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.
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 adjustments 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 the
Maintenance Booklet.
