ROnly use the "Windshield defrosting" function
briefly until the windshieldisclear again.
ROnly use air-recirculation mode briefly, e.g. if
there are unpleasant outside odors or when in
at unnel. The windows could otherwise fog up,
since no fresh air is drawn into the vehicle in
air-recirculation mode.
ECO start/stop function
During automatic engine switch-off, the climate
control system only operates at areduced capa-
city. If you require the full climate control output,
you can switch off the ECO start/stop function
by pressing the ECO button (
Ypage 106).

Switchingc ooling with air dehumidification on/off
General notes
If you deactivate the "Cooling with air-dehumidification" function, the air inside the vehicle will not
be cooled. The air inside the vehicle will also not be dehumidified. The windows can fog up more
quickly. Therefore, only deactivate the "Cooling with air-dehumidification" function briefly.
The "Cooling with air dehumidification" function is only available when the engine is running.
The air inside the vehicle is cooled and dehumidified according to the temperature selected.
Condensation may drip from the underside of the vehicle when it is in cooling mode. This is normal
and not asign that there is amalfunction.

Problems with the "Cooling with air dehumidification" function
!If the cooling with air dehumidification does not switch on, it is possible that the climate control
system has lost coolant.

Setting climate control to automatic
General notes
In automatic mode, the set temperature is main-
tained at aconstant level. The system automat-
ically regulates the temperature of the dis-
pensed air, the airflow and the air distribution.
Automatic mode works best when cooling with
air dehumidification is also activated. If neces-
sary, cooling with air dehumidification can be
deactivated.

Important safety notes
GWARNING
Very hot or very cold air can flow from the air
vents. This could result in burns or frostbitei n
the immediate vicinity of the air vents. There
is ar isk of injury.
Make sure that all vehicle occupants always
maintain asufficient distance to the air out-
lets. If necessary, redirect the airflow to
another area of the vehicle interior.
In order to ensure the direct flow of fresh air
through the air ventsi nto the vehicle interior,
please observe the following notes:
Rkeep the air inlet between the windshield and
the hood free of blockages, such as ice, snow or leaves.
Rnever cover the air ventsora ir intake grilles in
the vehicle interior.
iFor virtually draft-free ventilation, adjust the
sliders of the air ventstot he center position.
iIf the automatic climate control constantly
differs from the set temperature or if unde-
