Useful information
i This Operator's Manual describes all
models and all standard and optional equip- ment of your vehicle available at the time of
publication of the Operator's Manual.
Country-specific differences are possible.
Please note that your vehicle may not be
equipped with all features described. This
also applies to safety-related systems and
functions.
i Read the information on qualified special-
ist workshops (Y page 25). Overview of climate control systems
General notes
Observe the settings recommended on the
following pages. The windows could other-
wise 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 dehumidifi-
cation function
R switch on the defrost windshield function
briefly, if required
Climate control regulates the temperature
and air humidity in the vehicle interior. The air filter cleans the air, thus improving the inte-
rior climate.
The "Cooling with air dehumidification" func-
tion is only available when the engine is run-
ning. Optimum climate control is only ach-
ieved with the side windows and roof closed.
The residual heat function can only be acti-
vated or deactivated with the ignition
switched off (Y page 139).
i Ventilate the vehicle for a brief period
during warm weather, e.g. using the con-
venience opening feature (Y page 95). This
will speed up the cooling process and the desired interior temperature will be
reached more quickly.
i The integrated filter filters out most par-
ticles of dust and soot and completely fil-
ters out pollen. It also reduces gaseous pol-
lutants and odors. A clogged filter reduces the amount of air supplied to the vehicle
interior. For this reason, you should alwaysobserve the interval for replacing the filter,which is specified in the Maintenance
Booklet. As it depends on environmental
conditions, e.g. heavy air pollution, the
interval may be shorter than stated in the
Maintenance Booklet.
i It is possible that the blower may be acti-
vated automatically 60 minutes after the
SmartKey has been removed depending on various factors, e.g. the outside tempera-
ture. The vehicle is then ventilated for
30 minutes to dry the climate control sys-
tem. 132

control
Climate control system Below, you can find a number of notes and
recommendations to help you use climate
control optimally.
R Activate climate control using the 0058
rocker switch. The indicator lamp in the
0058 rocker switch lights up.
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.
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 whenthe ignition is switched on. Overview of climate control systems
133Climate control

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
button (Y page 152). Operating the climate control sys-
tems Switching climate control on/off
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 135).
Activating/deactivating X
Turn the SmartKey to position 2in the igni-
tion lock (Y page 147).
X To activate: press the008Arocker switch
up or down.
The COMAND climate control menu opens.
X Activate climate control via the air-condi-
tioning setting bar in COMAND (see the
separate operating instructions).
X To deactivate: press the008Arocker
switch up or down.
The COMAND climate control menu opens.
X Deactivate climate control via the air-con-
ditioning setting bar in COMAND (see the
separate operating instructions). Activating/deactivating cooling with
air dehumidification
General notes 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-
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. If necessary, cooling
with air dehumidification can 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-
dows can fog up more quickly. Therefore,
deactivate the cooling with air-dehumidifica-
tion function only briefly. Setting climate control to automatic X

Setting the airflow
General notes You can select different airflow settings for
the driver's and front-passenger sides.

X Set the airflow using COMAND (see the
separate operating instructions). Switching the synchronization func-
tion on/off
Climate control can be set centrally using the synchronization function. The settings for
temperature, air distribution and airflow on
the driver's side are adopted for the front-
passenger side.
X To activate/deactivate: switch the syn-
chronization function on or off using
COMAND (see the separate operating
instructions).
The synchronization function switches off, if
the settings for the front-passenger side are
changed. Defrosting the windshield
You can use this function to defrost the wind-
shield or to clear a fogged up windshield or
front side windows on the inside.
Switch off the "Windshield defrosting" func-
tion as soon as the windshield is clear again.
X Turn the SmartKey to position 2in the igni-
tion lock (Y page 147).
X To activate: press the0064rocker switch

0050
0050Solutions The rear window
defroster has deactiva-
ted prematurely or can-
not be activated. The battery has not been sufficiently charged.
X Switch off any consumers that are not required, e.g. reading
lamps, interior lighting or the seat heating.
When the battery is sufficiently charged, the rear window
defroster can be activated again. Activating/deactivating air-recircula-
tion mode
General notes You can also temporarily deactivate the flow
of fresh air manually if unpleasant odors are
entering the vehicle from outside. The air
already inside the vehicle will then be recir-
culated.
If you switch on air-recirculation mode, the
windows can fog up more quickly, in particu-
lar at low temperatures. Only use air-recircu-
lation mode briefly to prevent the windows
from fogging up.
Activating/deactivating X
Turn the SmartKey to position 2in the igni-
tion lock (Y page 147).
X To activate: press the0072rocker switch
up or down.
The indicator lamp in the 0072rocker
switch lights up.
Air-recirculation mode is automatically acti-
vated at high levels of pollution or at high out- side temperatures. The indicator lamp in the
0072 rocker switch is not lit when automatic
air-recirculation mode is activated. Outside
air is added after about 30 minutes.
X To deactivate: press the0072rocker
switch up or down.
The indicator lamp in the 0072rocker
switch goes out. Air-recirculation mode deactivates automati-
cally:
R after approximately five minutes at outside
temperatures below approximately 41 ‡
(5 †)
R after approximately five minutes if cooling
with air dehumidification is deactivated
R after approximately 30 minutes at outside
temperatures above approximately 41 ‡
(5 †) if the "Cooling with air dehumidifica-
tion" function is activated Activating/deactivating the residual
heat function
General notes Once the engine is switched off, it is possible
to make use of the residual heat of the engine to continue heating or ventilating the front
compartment of the vehicle for approximately
30 minutes.
The heating or ventilation time depends on
the temperature that has been set.
