Safe Driving
Oil Pressure Gauge
The oil pressure at idle speed may
d ro p to 0.3 bar/4.4 psi if the engine is
at operating tem perature. This will not
jeopardize its operational reliability.
Pressure must, however, rise
^ immediately upon acceleration.
The oil pressure gauge will not
B provide early warning of low oil level.
B Therefore, check oil level at regular
intervals w ith the dipstick.
Coolant Temperature Gauge
If the antifreeze m ixture is good to
— 30° C/ — 22° F, the boiling point of
the coolant in the pressurized cooling
system of your vehicle is approx.
125° C/257° F (see also “ Fuels, C ool­
ants, Lubricants, e tc .” ).
During severe operating conditions
and stop-and-go city traffic the
coolant tem perature m ust not rise
above the red marking.
Emission Control
Certain system s of the engine serve
to keep the to xic com ponents of the
exhaust gases w ithin perm issible
lim its required by law. (Nevertheless,
we urgently advise you not to let the
engine run in a closed garage.) These
system s, of course, will function
properly only when maintained strictly
according to factory specifications.
Any adjustm ents on the engine
should, therefore, be carried out only
by qualified MERCEDES-BENZ te ch ­
nicians. The adjustm ents of the
engine should not be altered in any
way. M oreover, the specified service
and maintenance jobs m ust be
carried out regularly according to
MERCEDES-BENZ servicing require­
m ents. For details refer to the
Maintenance Booklet.
Engine Oil Consumption
Engine oil consum ption can only be
determ ined after a certain mileage
has been covered. During the break-
in period, higher oil consum ption may
be noticed and is normal.
