Example: washer fluid reservoir
Depending on the vehicle version, the washer
fluid reservoir for the windscreen washer sys-
tem and the headlamp cleaning system has a
capacity of approximately 10 or 15 litres.
When the washer fluid level in the washer fluid
reservoir is too low, the on-board computer dis-
plays a grey event window with the

Add a washer fluid concentrate according to
Mercedes-Benz Specifications for Service Prod-
ucts Sheet No. 371.0 throughout the entire
year. Adjust the mixing ratio to suit the outside
temperature.
At temperatures above freezing, use a washer
concentrate for the summer to prevent smear-
ing. If there is a risk of frost, use a washer fluid
concentrate for winter to prevent the water from
freezing on the windscreen.

Cyclone dust prefilter
The cyclone dust prefilter is integrated into the
inlet port and increases the operating life of the
air filter in dusty conditions.
Dust particles escape from the inlet port on
extraction valves
:
to reduce clogging of the air
filter. Dust particles can collect in extraction
valves
:
and for this reason extraction
valves
:
must be emptied regularly. If you reg-
ularly drive in dusty areas, empty the valve at
least once per week and in the case of air with
high concentrations of dust, once a day. Also
check extraction valves
:
regularly for dam-
age. Have damaged extraction valves
:
replaced immediately at a qualified specialist
workshop.
