To preven tthe windows fromfogging up:
R switch offclimate control only briefly

Climate control regulates thetemper atureand
the humidity inthe vehicle interiorand filters
undesirable substancesout ofthe air.
Climate control can only beoperated whenthe
engin eisr unn ing. Optimum operation isonly achieved
withtheside windows androof
closed.

theweather iswarm, ventilate the
vehicle forabrief period. Thiswillspeed up
the cooling process andthedesired vehicle

cles ofdust andsoot andcomplet elyfilters
