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
activate the "Windshield defrosting" 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 139).
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 condi-
tions, e.g. heavy air pollution, the interval may
be shorter than stated in the Maintenance Book-
let.
i Ventilate the vehicle for a brief period during
warm weather, e.g. using the convenience
opening feature ( Y
page 92). This will speed
up the cooling process and the desired inte-
rior temperature will be reached more
quickly.
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 automatic climate control.
i Hybrid vehicles: be sure to observe the
notes in the supplement. Otherwise, you may
not recognize dangers.

Overview of climate control systems
Climate control

i 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.
Vehicles with 3-zone automatic climate control:
use the "Residual heat" function if you want to
heat or ventilate the vehicle interior when the
ignition is switched off. The residual heat func-
tion can only be activated or deactivated with
the ignition switched off. The residual heat func-
tion is deactivated when the ignition is switched
on.
DYNAMIC SELECT switch (except
Mercedes-AMG GLC 63 4MATIC/
GLC 63 S 4MATIC) You can choose between various drive programs
with the DYNAMIC SELECT switch
( Y
page 144).
If you have selected drive program E :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 142).
Operating the climate control sys-
tems
Activates/deactivates 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 128).
Activating/deactivating X
Turn the SmartKey to position H in the igni-
tion lock ( Y
page 136). 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.
Switching cooling with air dehumidification on/off
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. Operating the climate control systems 127

Problem
Possible causes/consequences and P Solutions
The engine is not running
smoothly and is misfir-
ing. There is a malfunction in the engine electronics or in a mechanical
component of the engine management system. X
Only depress the accelerator pedal slightly.
Otherwise, non-combusted fuel may get into the catalytic converter
and damage it. X
Have the cause rectified immediately at a qualified specialist work-
shop.
The coolant temperature
display indicates a value
within the red band. The coolant level is too low. The coolant is too hot and the engine is no
longer being cooled sufficiently. X
Stop as soon as possible and allow the engine and the coolant to
cool down. X
Check the coolant level ( Y
page 322). Observe the warning notes
as you do so and add coolant if necessary.
