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 interior
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.
If you start the engine using your smartphone,
the last selected climate control setting is reac-
tivated ( Y
page 149).
The residual heat function can only be activated
or deactivated with the ignition switched off
( Y
page 137).
i Ventilate the vehicle for a brief period during
warm weather, e.g. using the convenience
opening feature ( Y
page 96). 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-
ted 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. Overview of climate control systems 129
Climate control
Notes on using automatic climate
control
Optimum use of the automatic climate
control The following contains notes and recommenda-
tions on optimum use of the dual-zone or 3-zone
automatic climate control. R
Activate climate control using the X
rocker switch. The indicator lamp above the
X rocker switch lights up. The "Cooling
with air dehumidification" function is not acti-
vated automatically in automatic mode. If
necessary, activate this function
( Y
page 133).R
Set the temperature to 72 ‡ (22 †). R
Only use the "Windshield defrosting" function
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 otherwise fog up,
since no fresh air is drawn into the vehicle in
air-recirculation mode. R
Vehicles with 3-zone automatic climate con-
trol or PLUG-IN HYBRID: 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 deactivated with the igni-
tion switched off. The residual heat function is
switched off when the ignition is switched on.
DYNAMIC SELECT switch (except
Merc edes-AMG vehicles)You can choose between various drive programs
with the DYNAMIC SELECT switch
( Y
page 154).
If you have selected drive program E :R
the cooling output is reduced when cooling R
when heating, the electrical heater booster is
deactivated and heat output is reduced as a
result R
the rear window defroster running time is
reduced
If you have selected drive program C , S or S+ ,
the current climate settings are maintained. ECO start/stop function During automatic engine switch-off, the climate
control system only operates at a reduced capa-
city. If you require the full climate control output,
you can switch off the ECO start/stop function
by pressing the ECO button ( Y
page 151).
Operating the climate control sys-
tems
Activating/deactivating climate con-
trol
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
X rocker switch ( Y
page 133).
Switching on/off X
Turn the SmartKey to position 2 in the ignition
lock ( Y
page 146). X
To switch on: set the airflow to level 1 or
higher using the H rocker switch.X
To switch off: set the airflow to level 0 using
the H rocker switch.
i 3-zone automatic climate control: when cli-
mate control is switched off, "OFF" appears in
the rear-compartment display.132
