Overview of climate control systems
General notes
Observe the settings recommended on the fol-lowing pages. The windows could otherwise fogup.
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" functionbriefly, if required
Climate control regulates the temperature andair humidity in the vehicle interior. The interiorfilter cleans the air, thus improving the interiorclimate.
The "Cooling with air dehumidification" functionis only available when the engine is running.Optimum climate control is only achieved withthe side windows and roof closed.
If you start the engine using your smartphone,the last selected climate control setting is reac-tivated (Ypage 134).
The integrated filter filters out most particles ofdust and soot and completely filters out pollen.It also reduces gaseous pollutants and odors. Aclogged filter reduces the amount of air suppliedto the vehicle interior. For this reason, youshould always observe the interval for replacingthe filter, which is specified in the MaintenanceBooklet. As it depends on environmental condi-tions, e.g. heavy air pollution, the interval maybe shorter than stated in the Maintenance Book-let.
iVentilate the vehicle for a brief period duringwarm weather, e.g. using the convenienceopening feature (Ypage 91). This will speedup the cooling process and the desired inte-rior temperature will be reached morequickly.
iIt is possible that the blower may be activa-ted automatically 60 minutes after the Smart-Key has been removed depending on variousfactors, e.g. the outside temperature. Thevehicle is then ventilated for 30 minutes to drythe automatic climate control.

DSets the air distribution, left (Ypage 124)

Vehicles with 3-zone automatic climate control:use the "Residual heat" function if you want toheat or ventilate the vehicle interior when theignition is switched off. The residual heat func-tion can only be activated or deactivated withthe ignition switched off. The residual heat func-tion is deactivated when the ignition is switchedon.
DYNAMIC SELECT switch (except
Mercedes-AMG GLC 63 4MATIC/
GLC 63 S 4MATIC)
You can choose between various drive programswith the DYNAMIC SELECT switch(Ypage 139).
If you have selected drive programE:
Rwhen heating, the electrical heater booster isdeactivated and heat output is reduced as aresult
Rthe rear window defroster running time isreduced
If you have selected drive programC,SorS+,the current climate settings are maintained.
ECO start/stop function
During automatic engine switch-off, the climatecontrol system only operates at a reduced capa-city. If you require the full climate control output,you can switch off the ECO start/stop functionby pressing the ECO button (Ypage 137).

tems
Activating/deactivating climate con-
trol
General notes
When the climate control is switched off, the airsupply and air circulation are also switched off.The windows could fog up. Therefore, switch offclimate control only briefly
Switch on climate control primarily using theXrocker switch (Ypage 123).
Activating/deactivating
XTurn the SmartKey to positionHin the igni-tion lock (Ypage 131).
XTo switch on:set the airflow to level1orhigher using theHrocker switch.
XTo switch off:set the airflow to level0usingtheHrocker switch.
i3-zone automatic climate control: when cli-mate control is switched off, "OFF" appears inthe 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 notbe cooled. The air inside the vehicle will also not be dehumidified. The windows can fog up morequickly. 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 airinside 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 normaland not a sign that there is a malfunction.
Activating/deactivating
XPress theZrocker switch up or down.The indicator lamp above the rocker switch lights up or goes out.

ProblemPossible causes/consequences andPPSolutions
The indicator lamp abovetheZrocker switchremains off. The coolingwith air dehumidificationfunction cannot be acti-vated via the multimediasystem any longer(Ypage 273).
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. Thesystem automatically regulates the temperatureof the dispensed air, the airflow and the air dis-tribution.
During automatic controlling, the "Cooling withair dehumidification" function is activated.
Automatic control
XTurn the SmartKey to positionHin the igni-tion lock (Ypage 131).
XTo activate:press theXrocker switch upor down.The indicator lamp above theXrockerswitch lights up.
XSet the desired temperature using the

3-zone automatic climate control
XActivate or deactivate the "Synchronization"function using the multimedia system(Ypage 273).
The synchronization function is deactivated:
Rif the settings for the front-passenger side arechanged
Rthe settings for the rear compartment arechanged
Defrosting the windshield
General notes
You can use this function to defrost the wind-shield or to clear a fogged up windshield or frontside windows on the inside.
Switch off the "Windshield defrosting" functionas soon as the windshield is clear again.
Switching the "Windshield defrosting"
function on or off
XTurn the SmartKey to positionHin the igni-tion lock (Ypage 131).
XTo switch on:press rocker switchdonthe front control unit up or down.The indicator lamp above thedrockerswitch lights up. The current climate controlsettings are deactivated.
The climate control system switches to thefollowing functions:
Rhigh airflow
Rhigh temperature
Rair distribution to the windshield and frontside windows
Rair-recirculation mode off
iIf necessary, the "Cooling with air dehumid-ification" function is activated. In this case,the indicator lamp above theZrockerswitch remains switched off.
XTo switch off:press rocker switchdup ordown.The indicator lamp above thedrockerswitch goes out. The previously selected set-
tings are restored. Air-recirculation moderemains deactivated.
