Drive Sensibly - Save Fuel
Fuel consumption to a great extent
depends on driving habits and operat
ing conditions.
To save fuel you should:
• keep tires at the recommended
inflation pressures
• remove unnecessary loads
• remove ski racks or roof-mounted
luggage racks when not in use
• allow engine to warm up under low
load use
• avoid frequent acceleration and
deceleration
• have all maintenance work per
formed at regular intervals by an
authorized MERCEDES-BENZ
dealer.
Fuel consumption is also increased
by driving in cold weather in stop-
and-go traffic on short trips and in
hilly country.

The First 1500 km (1000 Miles)
The more cautiously you treat your
vehicle during the break-in period the
more satisfied you will be with its per
formance 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 RPM
(no more than % of maximum per
missible speed in each gear).
Avoid accelerating by kickdown. It is
not recommended to brake the
vehicle by 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.
