automatic climate control (2‑zone)
THERMATIC automatic climate control The following contains notes and recommen-
dations on optimum use of THERMATIC auto-
matic climate control.
R Activate climate control using the Ã
rocker switch. The indicator lamp above
the à rocker switch lights up. The "Cool-
ing with air dehumidification" function is
not activated automatically in automatic mode. If necessary, activate this function
(Y page 161).
R Set the temperature to 22 †.
R Only use the windscreen demisting func-
tion briefly until the windscreen is clear
again.
R Only use air-recirculation mode briefly, e.g.
if there are unpleasant outside odours or
when in a tunnel. The windows could oth-
erwise mist up as no fresh air is drawn into
the vehicle in air-recirculation mode. 156
