Safe Driving
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 reliability. Pressure
must, however, rise immediately
upon acceleration.
The oil pressure gauge will not pro­
vide early warning of low oil level.
Therefore, check oil level at regular
intervals with the dipstick.
Coolant Temperature Gauge
Due to the pressurized cooling sys­
tem, the coolant only starts boiling
at a temperature of approx. 125° C/
257° F with an anti-corrosion/anti­
freeze-blended coolant fill protect­
ing 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.
Emission Control
Certain systems of the engine
serve to keep the toxic com­
ponents 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 sys­
tems, of course, will function
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 re­
quirements. For details refer to the
Maintenance Booklet.
Engine Oil Consumption
Engine oil consumption can only be
determined after a certain mileage
has been covered. During the
break-in period, higher oil con­
sumption may be noticed and is
normal.
