Optimum use of dual-zone climate
control
The following contains notes and recommen-
dations on optimum use of dual-zone climate
control.
You can switch on climate control by using
R
the à and ¿ or à and Á but-
tons. The indicator lamps in the à and
¿ buttons or the à and Á but-
tons 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 sepa-
rate operating instructions). 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 170).
