notes
Observe thesettings recom mended onthe fol-
lowing pages. Thewindows couldotherwisefog
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 ature
and thehumidity ofthe vehicle interiorand fil-
ters undesirable substancesfrom theair.
The air-con ditionin gsystem ordual-zon eauto-
matic climate control can only beoperated
when theengin eis runn ing.Optimum operation
is only achieved withtheside windows andpan-
orama roofwith power tilt/sliding panelclosed.
If you start theengine usingyoursmart phone,
the last select edclimate control settingisreac-
tivat ed(Ypage 83).
The residual heatfunctioncanonly beactivat ed
or deactivat edwith theignition switched off
(Y page 120). Always
keepthevent ilation flapsbehind the
side trimpanel inthe cargo compart mentclear
(Y page 107). Otherwisethevehicle willnotbe
vent ilated correctly.
i Vent
ilate thevehicle forabrief period during
warm weather, e.g.using theconvenien ce
opening feature(Ypage 83).This willspeed
up the cooling process andthedesired inte-
rior temper aturewillbereached more
quickly.
i The
integ rated filterfilters outmost parti-
cles ofdust andsoot andcomplet elyfilters
out pollen. Italso reduces gaseous pollutant s
and odors. Aclogged filterreduces the
amount ofair supplied tothe vehicle interior.
For this reason, youshould alwaysobserve
the inter valforreplacing thefilter, which is
specified inthe Mainten anceBooklet.Asit
depends onenviro nmentalcon ditions ,e.g.
heavy airpollution, theinter valmay be
short erthan statedinthe Mainten anceBook-
let.
i It
is possible thatunder certaincirc umstan -
ces theresidual heatfunction may beactiva-
