Notes on using automatic climate
control
Climate control system
Below, you can find a number of notes and
recommendations to help you use climate
control optimally.
Activate climate control using the Ã
R
rocker switch. The indicator lamp in the
à rocker switch lights 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 residual heat function if you want to
R
heat or ventilate the vehicle interior when
the ignition is switched off. The residual
heat function can only be activated or deac-
tivated 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 follow-
ing:
If you set rear-compartment climate con-
R
trol using the front control panel, the Y
symbol appears in the rear-compartment
control panel display.
If the rear-compartment climate control is
R
set using the front control panel, it cannot
be set at the same time using the rear con-
trol 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.
After selecting the rear compartment set-
R
tings, the front climate control can be con-
trolled automatically again via COMAND
after five seconds.

Alternatively, you can select "Cancel rear
compartment" in the COMAND air-condi-
