Drive Sensibly — Save Fuel
Fuel consumption depends to a great
extent on driving habits and operating
conditions
In order to save fuel you should:
• ensure that tire pressures are
correct
• not carry unnecessary loads
• remove ski racks or roof-mounted
luggage racks when not in use
• not warm up your engine at idle
and with the vehicle at standstill
• avoid frequent acceleration and
deceleration
• avoid frequent braking
• avoid unnecessarily high speeds
• have all the maintenance jobs
specified by us carried out at
regular intervals by a
MERCEDES-BENZ service station
Driving in low temperature weather, in
stop-and-go city traffic and on short
hops, and in hilly country as well,
increases fuel consumption
