Overview of climatecontrol systems
General notes
Observe the settings recommended on the fol-
lowing pages. The windows could otherwise fog
up.
To preventt he 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 function
briefly, if required
Climate control regulates the temperature and
air humidity in the vehicle interior. The interior
filter cleans the air, thus improvingt he 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 vehicle via your smartphone, the
last selected climate control setting is activated
(
Ypage 134).
iVentilate the vehicle for abrief period during
warm weather, e.g. using the convenience
opening feature (
Ypage 88). This will speed
up the cooling process and the desired inte-
rior temperature will be reached more
quickly.
iThe integrated filter filters out most parti-
cles of dust and soot and completely filters
out pollen. It also reduces gaseous pollutants
and odors. Aclogged filter reduces the
amount of air supplied to the vehicle interior.
For this reason, you should alwayso bserve
the interval for replacing the filter, which is
specified in the Maintenance Booklet. As it
depends on environmental conditions ,e.g.
heavy air pollution, the interval may be
shorter than stated in the Maintenance Book- let.
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 climate control system.
