Safe Driving Driving Economically
The First 1,000 Miles (1,500 km)
Emission Control
Special devices of the engine
and/or adjustments 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,
because in such cases the danger
of carbon monoxide poisoning still
exists). These devices, of course,
will function properly only when
maintained strictly according to
factory specifications. Any adjust­
ments on the engine should, there­
fore, be carried out only by qualified
MERCEDES-BENZ technicians. The
devices may not be disconnected
or removed nor the adjustments be
altered in any way. Moreover, the
specified service and maintenance
jobs must be carried out regularly
according to MERCEDES-BENZ
servicing requirements. These serv­
ice and maintenance jobs partic­
ularly require the checking of the
carbon monoxide content, the
adjustment of the engine idling
speed and distributor timing. For
details refer to the Emission
Systems Manual.
Fuel Consumption
Fuel consumption depends to a
great extent on driving habits and
operating conditions. For econo­
mical driving you should
• avoid frequent and quick
acceleration
• avoid frequent slowdowns
• avoid high speeds
Driving in low temperature weather,
in stop-and-go city traffic and on
short hops, and in hilly country
also increases fuel consumption.
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.
Frequent high engine speed opera­
tion will also cause increased oil
consumption.
The more cautiously you treat your
engine during the break-in period,
the more satisfied you will be with
its performance later on. There­
fore, drive your vehicle during the
first 1,000 miles (1,500 km) at mod­
erate vehicle and engine speeds.
During this period, avoid heavy
loads (full throttle driving) and high
RPMs (no more than
2h
of maxi­
mum 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
vehicle by means of manually shift­
ing to a lower gear. We recommend
to select positions “ S” or “ L"
only at moderate speeds (for hill
driving).
After 1,000 miles (1,500 km), speeds
may gradually be increased to the
permissible maximum.
