R Activate climate control using the 0058
rocker switch. The indicator lamp above
the 0058 rocker switch lights up. The "Cool-
ing with air dehumidification" function is
not activated automatically in automatic mode. If necessary, activate this function
(Y
page 143).
R Set the temperature to 72 ‡ (22 †).
R Only use the "Windshield defrosting" func-
tion briefly until the windshield is clear
again.
R Only use air-recirculation mode briefly, e.g.
if there are unpleasant outside odors or
when in a tunnel. The windows could oth-
erwise fog up, since no fresh air is drawn
into the vehicle in air-recirculation mode. Overview of climate control systems

You can choose between various drive pro-
grams with the AGILITY SELECT switch
(Y

If you have selected the drive program E, the
climate control switches to Eco mode.
In Eco mode:
R the cooling output is reduced when cooling
R when heating, the electrical heater booster
is deactivated and heat output is reduced
as a result
R the rear window defroster running time is
reduced
If you have selected the drive program C,S or
S+ the climate control switches to Comfort

are maintained in Comfort mode.
ECO start/stop function During automatic engine switch-off, the cli-
mate control system only operates at a
reduced capacity. If you require the full cli-
mate control output, you can switch off the
ECO start/stop function by pressing the ECO

3-zone automatic climate control The following contains instructions and rec-
ommendations to enable you to get the most
out of your 3-zone automatic climate control.
R Activate climate control using the 0058
rocker switch. The indicator lamp above
the 0058 rocker switch lights up. The "Cool-
ing with air dehumidification" function is
not activated automatically in automatic
mode. If necessary, activate this function

if there are unpleasant outside odors or
when in a tunnel. The windows could oth-
erwise fog up, since no fresh air is drawn
into the vehicle in air-recirculation mode.
R Use the residual heat function if you want to
heat or ventilate the vehicle interior when
the ignition is switched off. The residual
heat function can only be activated or deac-
tivated with the ignition switched off. The
residual heat function is switched off when the ignition is switched on.

air dehumidification
General notes If you deactivate the "Cooling with air-dehu-

cle will also not be dehumidified. The win-
dows can fog up more quickly. Therefore,
deactivate the cooling with air-dehumidifica-
tion function only briefly.
The "Cooling with air dehumidification" func-
tion is only available when the engine is run-
ning. 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 isnormal and not a sign that there is a malfunc-
tion.

General notes In automatic mode, the set temperature is
maintained automatically at a constant level.
The system automatically regulates the tem-
perature of the dispensed air, the airflow and
the air distribution.
The automatic mode functions optimally
when the "Cooling with air dehumidification"
function is activated. The "Cooling with air
dehumidification" function must be activated
manually in automatic mode. If necessary,
"Cooling with air dehumidification" can also
be deactivated.
If you deactivate the "Cooling with air-dehu-
midification" function, the air inside the vehi- cle will not be cooled. The air inside the vehi-
cle will also not be dehumidified. The win-
