Automatic climate control
The automatic climate control is operation-
al whenever the engine is running. You can
operate the climate control system in ei-
ther the automatic or manual mode. The
system cools or heats the interior depend-
ing on the selected interior temperature
and the current outside temperature.
It can only function optimally when you are
driving with the windows and the tilt/slid-
ing sunroof/panorama sunroof* closed.
It is possible to completely deactivate the
climate control system (
୴ page 428).
Nearly all dust particles, pollutants and
odors are filtered out before outside air en-
ters the passenger compartment through
the air distribution system.
The following automatic climate control
functions can be operated via COMAND:
i
If you have the air distribution and air vol-
ume automatically controlled, you can adjust the
temperature, footwell temperature and air flow.
The following basic settings are recommended:
ț Automatic air distribution control
(
୴ page 428)
ț Temperature: 72°F (22°C) (୴ page 429)
ț Footwell temperature: 0 (୴ page 232)
ț Air flow: focused (୴ page 233)
Warning! G
Follow the recommended settings for heat-
ing and cooling given on the following pages
and in the “COMAND automatic climate
control” section (
୴ page 229). Otherwise
the windows could fog up, impairing visibili-
ty and endangering you and others.
i
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.
If the vehicle interior is hot, ventilate the interior
before driving off, see “Summer opening fea-
ture” (
୴ page 355). The automatic climate con-
trol 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, leaves, sticks, and any other
debris.
Do not obstruct air volume by placing objects on
the air volume-through exhaust slots below the
rear window.
