The following contains notes and recommenda-
tions on how best to use dual-zone automatic
climate control or 3-zone automatic climate
control (vehicles in Canada only).
XActivate climate control using the Ã
rocker switch. The indicator lamp above the
à rocker switch lights up. The "Cooling
with dehumidification" function is activated in
automatic mode.
XSet the temperature to 72 ‡ (22 †).
iOnly use the "Windshield defrosting" func-
tion briefly until the windshield is clear again.
iOnly 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.
Vehicles with 3-zone automatic climate control:
use the "Residual heat" function if you want to
heat or ventilate the vehicle interior when the
ignition is switched off. The residual heat func-
tion can only be activated or deactivated with
the ignition switched off. The residual heat func-
tion is switched off when the ignition is switched on.
