Safe Driving The First 1500 km/1000 Miles
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 function
properly only when maintained strictly
according to factory specifications.
Any adjustments on the engine
should, therefore, be carried out only
by qualified MERCEDES-BENZ techn­
icians. 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 requirements. 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 consumption may
be noticed and is normal.
The more cautiously you treat your
engine during the break-in period, the
more satisfied you will be with its
performance later on. Therefore,
drive your vehicle during the first
1500 km/1000 miles at moderate
vehicle and engine speeds.
During this period, avoid heavy loads
(full throttle driving) and high RPMs
(no more than
2/3
of maximum
permissible speed in each gear) and
do not force the engine to labor at low
engine speed.
Avoid accelerating by kickdown. It is
not recommended to brake the
vehicle by means of manually shifting
to a lower gear. We recommend to
select positions “ 3” or “ 2” only at
moderate speeds (for hill driving).
After 1500 km/1000 miles speeds
may gradually be increased to the
permissible maximum.
