Optimum use of 3-zone automatic cli-
mate control
3-zone automatic climate control
The following contains instructions and rec-
ommendations to enable you to get the most
out of your 3-zone automatic climate control.
R Activate climate control using the Ã
rocker switch. The indicator lamp above
the à rocker switch lights up. The "Cool-
ing with air dehumidification" function is
not activated automatically in automatic
mode. If necessary, activate this function
(
Y
page 143).
R Set the temperature to 72 ‡ (22 †).
R Only use the "Windshield defrosting" func-
tion 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 oth-
erwise 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 deac-
tivated with the ignition switched off. The
residual heat function is switched off when
the ignition is switched on.
AGILITY SELECT switch
You can choose between various drive pro-
grams with the AGILITY SELECT switch
(
Y
page 167).
If you have selected the drive program E, the
climate control switches to Eco mode.
In Eco mode:
R the cooling output is reduced when cooling
R when heating, the electrical heater booster
is deactivated and heat output is reduced
as a result
R the rear window defroster running time is
reduced
If you have selected the drive program C, S or
S+ the climate control switches to Comfort
mode. The current climate control settings
are maintained in Comfort mode.
ECO start/stop function
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 (
Y
page 162).
