Overview of climate control systems
General notes
Observe the settings recommended on the fol-
lowing pages. The windows could otherwise fog up.
To prevent the windows from fogging up:
R switch off climate control only briefly
R switch on air-recirculation mode only briefly
R switch on the cooling with air dehumidifica-
tion function
R activate the "Windshield defrosting" function
briefly, if required
Climate control regulates the temperature and
air humidity in the vehicle interior. The interior
filter cleans the air, thus improving the interior
climate.
The cooling with air dehumidification function is only available when the engine is running. Opti-mum climate control is only achieved with the
side windows closed. i
Ventilate the vehicle for a brief period during
warm weather, e.g. using the convenience
opening feature (Y page 78). This will speed
up the cooling process and the desired inte-
rior temperature will be reached more
quickly.
i The integrated filter filters out most parti-
cles of dust and soot and completely filters
out pollen. It also reduces gaseous pollutants and odors. A clogged filter reduces the
amount of air supplied to the vehicle interior.
Depending on the operating conditions and
environmental influences, the interval for
replacing the filter may be shorter than speci- fied.
i It is possible that the blower may be activa-
ted automatically 60 minutes after the engine has been switched off depending on various
factors, e.g. the outside temperature. The
vehicle is then ventilated for 30 minutes to drythe climate control system. Control panel for dual-zone automatic climate control

climate control
Dual-zone automatic climate control The following contains instructions and recom-
mendations to enable you to get the most out of
your dual-zone automatic climate control:
R Activate climate control using the 0058
rocker switch. The indicator lamp above the
0058 rocker switch lights up. The "Cooling
with air dehumidification" function is not acti- vated automatically in automatic mode. If
necessary, activate this function
(Y page 104).
R Set the temperature to 72 ‡ (22 †).
R Only use the "Windshield defrosting" function
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 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 a reduced capa-
city. If you require the full climate control output, you can switch off the ECO start/stop function
by pressing the ECO button (Y page 114).Operating the climate control sys-
tems Setting climate control
General notes When the climate control is switched off, the air
supply and air circulation are also switched off. The windows could fog up. Therefore, switch off
climate control only briefly
Switch on climate control primarily using the
0058 rocker switch (Y page 105).
Activating/deactivating X
Select key position 0048with the Start/Stop
button (Y page 111).
X To switch on: set the airflow to level 1or
higher using the Hrocker switch.
X To switch off: set the airflow to level 0using
the H rocker switch. Switching cooling with air dehumidi-
fication on/off
General notes If you deactivate the "Cooling with air-dehumid-
ification" 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, deactivate the cooling
with air-dehumidification function only briefly.
The "Cooling with air dehumidification" function is only available when the engine is running. Theair 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 a sign that there is a malfunc-
tion.
Activating/deactivating X
Press the 005Arocker switch up or down.

General notes In automatic mode, the set temperature is main-
tained automatically at a constant level. The
system automatically regulates the temperature of the dispensed air, the airflow and the air dis- tribution.
During automatic controlling, the "Cooling with
air dehumidification" function is activated.

General notes The rear window defroster has a high current
draw. You should therefore switch it off as soon
as the rear window is clear. Otherwise, the rear
window defroster switches off automatically
after several minutes.
If the battery voltage is too low, the rear window defroster may switch off. 106

defroster has deactiva-
ted prematurely or can-

General notes You can also temporarily deactivate the flow of
fresh air manually if unpleasant odors are enter-
ing the vehicle from outside. The air already
inside the vehicle will then be recirculated.
If you switch on air-recirculation mode, the win-
dows can fog up more quickly, in particular at
low temperatures. Only use air-recirculation
mode briefly to prevent the windows from fog-
ging up.

WARNING
Very hot or very cold air can flow from the air vents. This could result in burns or frostbite in the immediate vicinity of the air vents. There
is a risk of injury.
Make sure that all vehicle occupants always
maintain a sufficient distance to the air out-
lets. If necessary, redirect the airflow to
another area of the vehicle interior. Air vents
