Optimum use of dual-zone automatic
climate control
The following contains notes and recommen-
dations on optimum use of the dual-zone
automatic climate control.
Activate climate control using the à and
R
¿/Á buttons. The indicator lamps in
the à and ¿/Á buttons light up.
Set the temperature to 72 ‡ (22 †).
R
Only use the "Windshield defrosting" func-
R
tion briefly until the windshield is clear
again.
Only use air-recirculation mode briefly, e.g.
R
if there are unpleasant outside odors or
when in a tunnel. The windows could oth-
erwise fog up, since no fresh air is drawn
into the vehicle in air-recirculation mode.
Use the ZONE function to adopt the tem-
R
perature settings on the driver's side for
the front-passenger side as well. The indi-
cator lamp above the á button goes
out.
Vehicles with COMAND: if you change the
R
settings of the climate control system, the
climate status display appears for approx-
imately three seconds at the bottom of the
screen in the COMAND display. See also
the separate COMAND operating instruc-
tions. You will see the current settings of
the various climate control functions.
During automatic engine switch-off, the cli-
mate control system only operates at a
reduced capacity. If you require the full cli-
mate control output, you can switch off the
ECO start/stop function by pressing the ECO
button ( page 163).
