Useful information
iThis 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.
iRead the information on qualified
specialist workshops: (Ypage 28).
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:
Rswitch off climate control only briefly
Rswitch on air-recirculation mode only
briefly
Rswitch on the cooling with air
dehumidification function
Rswitch on the defrost windshield function
briefly, if required
Climate control regulates the temperature
and the humidity in the vehicle interior and
filters undesirable substances out of the air.
Climate control can only be operated when
the engine is running. Optimum operation 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 (Ypage 161).
iVentilate the vehicle for a brief period
during warm weather, e.g. using the
convenience opening feature (Ypage 95).
This will speed up the cooling process and
the desired interior temperature will be
reached more quickly.
iThe 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.
iIt is possible that the residual heat
function may be activated automatically an
hour after the SmartKey has been removed
in order to dry the automatic climate
control. The vehicle is then ventilated for
30 minutes.

Activating/deactivating cooling with
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,
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 a sign that there is a
malfunction.
Activating/deactivating
Example:Zbutton
XTo activate:press theZ/Vbutton.
The indicator lamp in theZ/V
button lights up.
XTo deactivate:press theZ/V
button.
The indicator lamp in theZ/V
button goes out. The "Cooling with air
dehumidification" function has a delayed
switch-off feature.

Setting climate control to automatic
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.
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.
Automatic mode will achieve optimal
operation if cooling with air dehumidification
is also activated. If necessary, cooling with air
dehumidification can be deactivated.
In the rear compartment, you can also switch
climate control for the rear seats to automatic
mode using theXbutton.
Activating/switching
XTurn the SmartKey to position2in the
ignition lock (Ypage 167).
XSet the desired temperature.
XTo activate:press theXbutton.
The indicator lamp in theXbutton lights
up. Automatic air distribution and airflow
are activated.
XTo switch to manual mode:press the
