Useful information
i This Operator's Manual describes all
models and all standard and optional
equipment 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
specialist workshops: (Y page 27).Overview of climate control systems
Important safety notes
Observe the settings recommended on the
following 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
dehumidification 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
interior climate.
The "Cooling with air dehumidification"
function is only available when the engine is
running. Optimum climate control is only
achieved with the side windows and roof
closed.
The residual heat function can only be
activated or deactivated with the ignition
switched off (Y page 163).
i Ventilate the vehicle for a brief period
during warm weather, e.g. using the
convenience opening feature
(Y page 100). This will speed up the cooling process and the desired interior
temperature will be reached more quickly.
i The integrated filter filters out most
particles 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. For this reason, you should
always observe 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
activated automatically 60 minutes after
the key has been removed depending on
various factors, e.g. the outside
temperature. The vehicle is then ventilated
for 30 minutes to dry the automatic climate
control. 152

air dehumidification
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,
deactivate the cooling with air-
dehumidification function only 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 a sign that there is a
malfunction.
Activating/deactivating cooling with
air dehumidification You can activate or deactivate the "Cooling
with air dehumidification" function using
COMAND (see the separate operating
instructions).156

malfunction.
X
Visit a qualified specialist workshop. Setting climate control to automatic
General notes In automatic mode, the set temperature is
maintained automatically at a constant level.
The system automatically regulates the
temperature 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-
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,
deactivate the cooling with air-
dehumidification function only briefly. Controlling front climate control

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. Activating/deactivating X
Turn the SmartKey to position 2in the

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-
recirculation 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
recirculated.
If you switch on air-recirculation mode, the
windows can fog up more quickly, in
particular at low temperatures. Only use air-
recirculation mode briefly to prevent the
windows from fogging up.
Activating/deactivating X
Turn the SmartKey to position 2in the
ignition lock (Y page 171).
X To activate: press the0072rocker switch
up or down.
The indicator lamp in the 0072rocker
switch lights up.
i Air-recirculation mode is automatically
activated at high levels of pollution or at
high outside temperatures. The indicator
lamp in the 0072rocker 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. i
Air-recirculation mode deactivates
automatically:
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 dehumidification" function is
activated Activating/deactivating the residual
heat function
General notes Vehicles with rear-compartment climate
control:
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 rear and front compartment of the vehicle
for approximately 15 minutes. If the "Residual
heat" function is set for only the front or only
the rear compartment, it is possible to
continue heating or ventilating for
approximately 30 minutes.
Vehicles without rear-compartment
climate control: 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. Operating the climate control systems
