Information about using dual-zone
automatic climate control
The following contains notes and
recommendations on optimum use of 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"
R
function 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
otherwise fog up, since no fresh air is drawn
into the vehicle in air-recirculation mode.
Use the ZONE function to adopt the
R
temperature settings on the driver's side
for the front-passenger side as well. The
indicator 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
approximately three seconds at the bottom
of the screen in the COMAND display. See
also the separate COMAND operating
instructions. You will see the current
settings of the various climate control
functions.
During automatic engine switch-off, the
climate control only operates at a reduced
capacity. If you require the full climate control
output, you can switch off the ECO start/stop
function by pressing the ECO button
( page 163).
