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
Climate control regulates thetemper atureand
the humidity inthe vehicle interiorand filters
undesirable substancesout ofthe air.
Climate control can only beoperated whenthe
engin eis runn ing.Optimum operation isonly achieved
withtheside windows androof
closed.
i When
theweather iswarm, ventilate the
vehicle forabrief period. Thiswillspeed up
the cooling process andthedesired vehicle

cles ofdust andsoot andcomplet elyfilters
