R Set th etem peratur etof72‡ (22 †).
R Only use th e"Windshield defrosting"
function briefly until th ewindshield is clear
again.
R Only use air-recirculation mod ebriefly, e.g.
if there are unpleasan toutside odor sor
when in atunnel. The windows could
otherwise fog up, since no fresh air is drawn
int ot he vehicl einair-recirculation mode.
R Use th eZON Efunction to adopt the
temperature setting sonthedriver's side
for the front-passenger side and the rear
compartment as well. The indicato rlamp
above the 0010button goes out.
R Use the residual heat function if you want
to heat or ventilate the vehicle interior
when the ignition is switched off. The
