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
Ractivate 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 (
Ypage 139).
The residual heat function can only be activated
or deactivated with the ignition switched off
(
Ypage 131). 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 92). This will speed
up the cooling process and the desired inte-
rior temperature 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. The
vehicle is then ventilated for 30 minutes to dry
the automatic climate control.
iHybrid vehicles: be sure to observe the
notes in the supplement. Otherwise, you may
not recognize dangers.

Optimum use of automatic climate
control
Optimum use of the automatic climate
control
The following contains notes and recommenda-
tions on how best to use dual-zone automatic
climate control or 3-zone automatic climate
control (vehicles in Canada only).
XActivate climate control using the Ã
rocker switch. The indicator lamp above the
à rocker switch lights up. The "Cooling
with dehumidification" function is activated in
automatic mode.
XSet the temperature to 72 ‡ (22 †).
iOnly use the "Windshield defrosting" func-
tion briefly until the windshield is clear again.
iOnly 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 switched off when the ignition is switched on.
DYNAMIC SELECT switch (except
Mercedes-AMG C 63 /C63S)
You can choose between various drive programs
with the DYNAMIC SELECT switch
(
Ypage 144).
If you have selected drive program E:
Rwhen heating, the electrical heater booster is
deactivated and heat output is reduced as a
result
Rthe rear window defroster running time is
reduced If you have selected drive program
C,Sor 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 (
Ypage 141).
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
à rocker switch (
Ypage 127).
Activating/deactivating
XTurn the SmartKey to position 2in the igni-
tion lock (Ypage 136).
XTo switch on: set the airflow to level 1or
higher using the Hrocker switch.
XTo switch off: set the airflow to level 0using
the H rocker switch.
i3-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.
Activating/deactivating
XPress the ¿rocker switch up or down.
The indicator lamp above the rocker switch lights up or goes out.
Problems with the "Cooling with air dehumidification" function
ProblemPossible causes/consequences and MSolutions
The indicator lamp above
the¿ rocker switch
remains off. The cooling
with air dehumidification
function cannot be acti-
vated via the multimedia
system any longer
(
Ypage 276).
Cooling with air dehumidification has been deactivated due to a mal-
function.
XVisit 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.
During automatic controlling, the "Cooling with
air dehumidification" function is activated.

however, continues to be controlled automati-
cally. When the manually set function switches
back to automatic mode, the indicator lamp
above the Ãrocker switch lights up again.

ProblemPossible causes/consequences andMSolutions
Vehicles with a gasoline
engine:
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.
XOnly depress the accelerator pedal slightly.
Otherwise, non-combusted fuel may get into the catalytic converter
and damage it.
XHave the cause rectified immediately at a qualified specialist work-
shop.
The coolant temperature
display is pointing to the
red mark.The coolant level is too low. The coolant is too hot and the engine is no
longer being cooled sufficiently.
XStop as soon as possible and allow the engine and the coolant to
cool down.
XCheck the coolant level (Ypage 306). Observe the warning notes
as you do so and add coolant if necessary.
