Overview of climate control systems
General notes
Observe the settings recommended on the fol-lowing pages. The windows could otherwisefog 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
Rswitch on the defrost windshield functionbriefly, if required
The air-conditioning system or dual-zone auto-matic climate control regulates the tempera-ture and the humidity of the vehicle interiorand filters undesirable substances from theair.
The air-conditioning system or dual-zone auto-matic climate control can only be operatedwhen the engine is running. Optimum opera-tion is only achieved with the side windowsand panorama roof with power tilt/slidingpanel closed.
If you start the engine using your smartphone,the last selected climate control setting isreactivated (Ypage 84).
The residual heat function can only be activa-ted or deactivated with the ignition switchedoff (Ypage 122).
Always keep the ventilation flaps behind theside trim panel in the cargo compartmentclear (Ypage 108). Otherwise the vehicle willnot be ventilated correctly.
iVentilate the vehicle for a brief period dur-ing warm weather, e.g. using the conveni-ence opening feature (Ypage 84). This willspeed up the cooling process and thedesired interior temperature will be reachedmore quickly.
iThe integrated filter filters out most parti-cles of dust and soot and completely filtersout pollen. It also reduces gaseous pollu-tants and odors. A clogged filter reduces theamount of air supplied to the vehicle inte-rior. For this reason, you should alwaysobserve the interval for replacing the filter,which is specified in the Maintenance Book-let. As it depends on environmental condi-tions, e.g. heavy air pollution, the intervalmay be shorter than stated in the Mainte-nance Booklet.
iIt is possible that under certain circum-stances the residual heat function may beactivated automatically an hour after theSmartKey has been removed in order to drythe automatic climate control. The vehicle isthen ventilated for 30 minutes.
