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
Rswitch on the defrost windshield functionbriefly, if required
The air-conditioning system or dual-zone auto-matic climate control regulates the temperatureand the humidity of the vehicle interior and fil-ters undesirable substances from the air.
The air-conditioning system or dual-zone auto-matic climate control can only be operatedwhen the engine is running. Optimum operationis only achieved with the side windows and pan-orama roof with power tilt/sliding panel closed.
If you start the engine using your smartphone,the last selected climate control setting is reac-tivated (Ypage 83).
The residual heat function can only be activatedor deactivated with the ignition switched off(Ypage 120).
Always keep the ventilation flaps behind theside trim panel in the cargo compartment clear(Ypage 107). Otherwise the vehicle will not beventilated correctly.
iVentilate the vehicle for a brief period duringwarm weather, e.g. using the convenienceopening feature (Ypage 83). This will speedup the cooling process and the desired inte-rior temperature will be reached morequickly.
iThe integrated filter filters out most parti-cles of dust and soot and completely filtersout pollen. It also reduces gaseous pollutantsand odors. A clogged filter reduces theamount of air supplied to the vehicle interior.For this reason, you should always observethe interval for replacing the filter, which isspecified in the Maintenance Booklet. As itdepends on environmental conditions, e.g.heavy air pollution, the interval may beshorter than stated in the Maintenance Book-let.
iIt is possible that under certain circumstan-ces the residual heat function may be activa-ted automatically an hour after the SmartKeyhas been removed in order to dry the auto-matic climate control. The vehicle is then ven-tilated for 30 minutes.
