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:
Rswitch off climate control only briefly
Rswitch on air-recirculation mode only briefly
Rswitch on the cooling with air dehumidifica-
tion function
Rswitch 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.
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.
If you start the engine using your smartphone,
the last selected climate control setting is reac-
tivated (
Ypage 123).
The residual heat function can only be activated
or deactivated with the ignition switched off
(
Ypage 116).
To enable the air conditioning, pollutant moni-
toring and air filtering systems to function cor-
rectly, an interior filter must be used at all times. Ensure that the filter is properly installed and
that the filter housing in the engine compart- ment is correctly and tightly sealed by the cover
at all times during operation. Use filters that
have been recommended and approved by
Mercedes-Benz. Always have service work car-
ried out at a qualified specialist workshop.
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 suppliedto 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 condi- tions, e.g. heavy air pollution, the interval may
be shorter than stated in the Maintenance Book-
let.
iVentilate the vehicle for a brief period during
warm weather, e.g. using the convenience
opening feature (
Ypage 86). This will speed
up the cooling process and the desired inte-
rior t
emperature will be reached more
quickly.
iIt is possible that the blower may be activa-
ted automatically 60 minutes after the Smart-
Key has been removed depending on various
factors, e.g. the outside temperature. In vehi-
cles with the KEYLESS-GO or KEYLESS-GO
start function, the blower can switch on auto-
matically after the engine has been switched
off and the door opened. The vehicle is then
ventilated for 30 minutes to dry the automatic
climate control.

Climate control

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.
During automatic controlling, the "Cooling with
air dehumidification" function is activated.
Setting climate control to automatic
XTurn the SmartKey to position 2in the ignition
lock (Ypage 121).
XSet the desired temperature using the 0082
rocker switch.
XTo activate: press the0058rocker switch up
or down.
The indicator lamp in the 0058rocker switch
lights up.
XTo switch to manual operation: press the
0097 rocker switch up or down.
The indicator lamp in the 0058rocker switch
goes out.
In automatic mode, if you adjust the airflow or
air distribution manually, the indicator lamp on
the 0058 rocker switch goes out. The function
which has not been changed manually, however,
continues to be controlled automatically. When
the manually set function switches back to auto-
matic mode, the indicator lamp on the 0058
rocker switch lights up again.
Adjusting the climate mode settings
In automatic mode you can select the following
airflow settings for the driver's and front-
passenger areas:
FOCUS high airflow, slightly cooler setting
MEDIUM medium airflow, standard setting
DIFFUSE low airflow, slightly warmer and draft- free setting
XTo set:set the climate mode using the mul-
timedia system (Ypage 247).
Setting the temperature
General notes
You can set the temperature separately for the
following areas:
Rfront footwells, left and right
Rdriver and front passenger area
Setting the temperature
XTurn the SmartKey to position 2in the ignition
lock (Ypage 121).
XTo increase or reduce: press the0082
rocker switch up or down.
XOnly change the temperature setting in small
increments. Start at 72 ‡ (22 †).
Setting the footwell temperature
The footwell temperature for the driver and front
passenger can be set separately using the mul-
timedia system (see the Digital Operator's Man-
ual).

Setting the air distribution via the mul-
timedia system
The air distribution for the left and right sides of
the driver's and front-passenger areas can be
adjusted using the multimedia system (see the
Digital Operator's Manual).
Setting the airflow
General notes
You can select different airflow settings for the
driver's and front-passenger sides.
Setting the airflow

iYou can also set the airflow using the mul-
timedia system (see the Digital Operator's
Manual).
Activating or deactivating the syn-
chronization function
Climate control can be set centrally using the
synchronization function. The settings for tem-
perature, air distribution and airflow on the driv-
er's side are adopted for the front-passenger
side.
XTo activate or deactivate: activate or deac-
tivate the "Synchronization" function via the
multimedia system (see the Digital Operator's
Manual).
The synchronization function deactivates if the
settings for the front-passenger side are
changed.
Defrosting the windshield
General notes
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" function
as soon as the windshield is clear again.
