2019 MERCEDES-BENZ SLC climate settings

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
Climate control regulates the temperature andthe humidity in the vehicle interior and filtersundesirable substances out of the air.
Climate control can only be operated when theengine is running. Optimum operation is only
achieved with the side windows and roofclosed.
iWhen the weather is warm, ventilate thevehicle for a brief period. This will speed upthe cooling process and the desired vehicleinterior 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 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.
