Notes on using climate control
Automatic climate control
Below, you can find a number of notes and
recommendations to help you use climate
control optimally.
R Activate climate control using the Ã
rocker switch. The indicator lamp in the
à rocker switch lights up.
R Set the temperature to 72 ‡ (22 †).
R Only use the "Windshield defrosting"
function briefly until the windshield is clear
again.
R Only 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.
R Use the residual heat function if you want
to heat or ventilate the vehicle interior
when the ignition is switched off. The
residual heat function can only be activated
or deactivated with the ignition switched
off. The residual heat function is switched
off when the ignition is switched on.
If you are controlling the rear climate control
using the front control panel, note the
following:
R If you set rear-compartment climate
control using the front control panel, the
Y symbol appears in the rear-
compartment control panel display.
R If the rear-compartment climate control is
set using the front control panel, it cannot
be set at the same time using the rear
control panel. If controlling the rear climate
control from the front control panel is
locked, wait five seconds. You will then be
able to control the rear climate control
using the rear control panel.
R After selecting the rear compartment
settings, the front climate control can be
controlled automatically again via
COMAND after five seconds.
Alternatively, you can select "Cancel rear
compartment" in the COMAND air-
conditioning function bar.
ECO start/stop function
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
(
