notes
Observe thesettings recom mended onthe fol-
lowing pages. Thewindows couldotherwise
fog up.
To preven tthe windows fromfogging up:
R switch offclimate control only briefly
R switch onair-rec irculation modeonlybriefly
R switch onthe cooling withairdehumidifica-
tion function
R switch onthe defrost windshield function
briefly, ifrequired
The air-con ditionin gsystem ordual-zon eauto-
matic climate control regulates thetemper a-
ture andthehumidity ofthe vehicle interior
and filters undesirable substancesfrom the
air.
The air-con ditionin gsystem ordual-zon eauto-
matic climate control can only beoperated
when theengin eis runn ing.Optimum opera-
tion isonly achieved withtheside windows
and panorama roofwith power tilt/sliding
panel closed.
If you start theengine usingyoursmart phone,
the last select edclimate control settingis
react ivated (Ypage 84).
The residual heatfunction canonly beactiva-
ted ordeactivat edwith theignition switched
off (Ypage 122). Always
keepthevent ilation flapsbehind the
side trimpanel inthe cargo compart ment
clear (Ypage 108). Otherwisethevehicle will
not bevent ilated correctly.
i Vent
ilate thevehicle forabrief period dur-
ing warm weather, e.g.using theconveni-
ence opening feature(Ypage 84).This will
speed upthe cooling process andthe
desired interiortemper aturewillbereached
more quickly.
i The
integ rated filterfilters outmost parti-
cles ofdust andsoot andcomplet elyfilters
out pollen. Italso reduces gaseous pollu-
tant sand odors. Aclogged filterreduces the
amount ofair supplied tothe vehicle inte-
rior. Forthis reason, youshould always
observe theinter valforreplacing thefilter,
which isspecified inthe Mainten anceBook-
let. Asitdepends onenviro nmentalcon di-
tion s,e.g. heavy airpollution, theinter val
may beshort erthan statedinthe Mainte-
nanc eBook let.
i It
is possible thatunder certaincirc um-
stan cestheresidual heatfunction may be
activat edautomatic allyanhour after the
Smart Keyhasbeen removed inorder todry
the automatic climatecontrol. Thevehicle is
then ventilated for30minut es. Overview
