The following contains notes and
recommendations on optimum use of dual-
zone automatic climate control.
R Activate climate control using the 0006and
0007/0005 buttons. The indicator lamps in
the 0006 and0007/0005 buttons light up.
R Set the temperature to 72 ‡ (22 †).
R Only use the "Windshield defrosting"
function briefly until the windshield is clear
again.
R Only use air-recirculation mode briefly, e.g.
if there are unpleasant outside odors or
when in a tunnel. The windows could
otherwise fog up, since no fresh air is drawn
into the vehicle in air-recirculation mode.
