To direct the airflow through the rear air vents
001E To direct the airflow through the footwell vents Information about using dual-zone
automatic climate control
The following contains notes and
recommendations on optimum use of dual-
zone automatic climate control.
R Activate climate control using the 0006and
0007/0005 buttons. The indicator lamps in
the 0006 and0007/0005 buttons light up.
R Set the temperature to 72 ‡ (22 †).
R Only use the 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 ZONE function to adopt the
temperature settings on the driver's side
for the front-passenger side as well. The
indicator lamp above the 0004button goes
out.
i During automatic engine switch-off, the
ECO start/stop function only operates at a
reduced capacity. If you require the full

more quickly. Only deactivate the cooling
with air dehumidification function for a short
time to preven tthe windows from fogging up.
The cooling with air dehumidification function
is only available when the engine is running.
The air inside the vehicle is cooled and
dehumidified according to the temperature
selected.
Condensation may drip from the underside of
the vehicle when it is in cooling mode. This is
normal and not a sign that there is a
malfunction.
Activating/deactivating Example:

indicator lamp in the button flashes three
times or remains off. You can no longer switch
on the cooling with air dehumidification
function.
X Visit a qualified specialist workshop. Setting climate control to automatic
Points to observe before use If you switch off the cooling function, the
vehicle will not be cooled when weather
conditions are warm. The windows can fog up
more quickly. Only deactivate the cooling
with air dehumidification function for a short
time to prevent the windows from fogging up.
In automatic mode, the set temperature is
maintained automatically at a constant level.
The system automatically regulates the
temperature of the dispensed air, the airflow
and the air distribution.
Automatic mode will achieve optimal
operation if cooling with air dehumidification
is also activated. If necessary, cooling with air
dehumidification can be deactivated.
In the rear compartment, you can also switch
climate control for the rear seats to automatic
mode using the 0006button.
