Warning! G
Severe conditions (e.g. strong air pollution)
may require replacement of the filter before
its scheduled interval. A clogged filter will
reduce the air volume to the interior and the
windows could fog up, impairing visibility
and endangering you and others. Have a
clogged filter replaced as soon as possible
at an authorized Mercedes-Benz Light Truck
Center.
Warning! G
Follow the recommended settings for heat-
ing and cooling given on the following
pages. Otherwise the windows could fog up,
impairing visibility and endangering you and
others.

If the vehicle interior is hot, ventilate the in-
terior before driving off, see “Summer opening
feature” (
୴ page 237). The automatic climate
control will then adjust the interior temperature
to the set value much faster.
Keep the air intake grille in front of the wind-
shield free of snow and debris.
Warning! G
When the automatic climate control system
is switched off, the outside air supply and
circulation are also switched off. Only
choose this settings for a short time. Other-
wise the windows could fog up, impairing
visibility and endangering you and others.
