Notes on using 3-zone automatic
climate control
Automatic climate control The following contains instructions and
recommendations to enable you to ge tthe
most out of your automatic climate control.
R Activate climate control using the 0004and
0005 buttons. The indicator lamps in the
0004 and0005 buttons light up.
R In automatic mode, you can also use the
000A button to adjust airflow (FOCUS/
MEDIUM/DIFFUSE). The MEDIUM level is
recommended.
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 ZONE function to adopt the
temperature settings on the driver's side
for the front-passenger side and the rear
compartmenta s well.The indicator lamp in
the 0003 button goes out.
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.
ECO start/stop function During automatic engine switch-off, the ECO
start/stop function only operates at a

Switching climate control on/off
Points to observe before use When the climate control is switched off, the
air supply and air circulation are also
switched off. Only use this setting for a brief
period. The windows could otherwise fog up.
Only switch off climate control briefly to
prevent the windows from fogging up.

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.

particular at low temperatures. Only use air-
recirculation mode briefly to prevent the
windows from fogging up.
You can deactivate the flow of fresh air if
unpleasant odors are enteringt he vehicle
from outside. The air already inside the
vehicle will then be recirculated.
The operation of air-recirculation mode is the
same for all control panels.

Important safety notes
G
WARNING
Very hot or very cold air can flow from the air
vents. This could result in burns or frostbite in
the immediate vicinity of the air vents. There
is a risk of injury.
Make sure that all vehicle occupants always
maintain a sufficient distance to the air
outlets. If necessary, redirect the airflow to
another area of the vehicle interior.
In order to ensure the direct flow of fresh air
through the air vents into the vehicle interior,
please observe the following notes:
R keep the air inlet between the windshield
and the hood free of blockages, such as ice,
snow or leaves.
R never cover the air vents or air intake grilles
in the vehicle interior.
