Useful information
i This Operator's Manual describes all models
and all standard and optional equipment of
your vehicle available at the time of publica-
tion of the Operator's Manual. Country-spe-
cific 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 28).
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
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 cli-
mate.
For vehicles with a combustion engine, the
"Cooling with air dehumidification" function is
only available when the engine is running. For
hybrid vehicles, the "Cooling with air dehumidi-
fication" function is also available via the elec-
tric refrigerant compressor when the engine is
not running. Optimum climate control is only
achieved with the side windows and roof closed.
If you start the engine using your smartphone,
the last selected climate control setting is reac-
tivated ( Y
page 164).
The residual heat function can only be activated
or deactivated with the ignition switched off
( Y
page 152).
i Ventilate the vehicle for a brief period during
warm weather, e.g. using the convenience
opening feature ( Y
page 95). 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.
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 Book-
let.
i It is possible that the blower may be activa-
t ed automatically 60 minutes after the Smart-
Key has been removed depending on various
factors, e.g. the outside temperature. The
vehicle is then ventilated for 30 minutes to dry
the climate control system.140

Problems with the "Cooling with air dehumidification" function Problem
Possible causes/consequences and P Solutions
The indicator lamp in the
V button flashes
three times or remains
off. Cooling with air
dehumidification can
also no longer be activa-
ted using the multimedia
system (see the sepa-
rate operating instruc-
tions). Cooling with air dehumidification has been deactivated due to a mal-
function. X
Visit a qualified specialist workshop.
Setting climate control to automatic
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.
The "Cooling with air dehumidification" function
is activated automatically in automatic mode.

Problems with the rear window defroster Problem
Possible causes/consequences and P Solutions
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.
Switching air-recirculation mode
on/off
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.

tion" function is activated
Switching the residual heat on or off
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 approx-
imately 30 minutes.
The heating or ventilation time depends on the
temperature that has been set.152
