pends on driving habits and operating con-
ditions.
To save fuel you should:

Keep tires at the recommended infla-
tion pressures


Remove unnecessary loads


Remove roof rack when not in use


Allow engine to warm up under low
load use


Avoid frequent acceleration and decel-
eration


Have all maintenance work performed
by qualified technicians at the intervals
specified in the Service Booklet and as
required by the FSS. Contact your au-
thorized Mercedes-Benz Center
Fuel consumption is also increased by driv-
ing in cold weather, in stop-and-go traffic,
on short trips and in hilly country.
