i Notes/tips
Only use the "defrosting" function briefly until the
windshield is clear again.
Use the ZONE function to adopt the temperature
settings on the driver's side for the front-passenger
side and the rear compartment as well. The indicator
lamp above the á button goes out.
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, as in air-
recirculation mode, no fresh air is drawn into the
vehicle.
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.
Activate climate control using the à and ¿
buttons. The indicator lamps above the à and
¿ buttons light up. You can also set the airflow
and air distribution of the automatic climate control
to one of three levels (FOCUS/MEDIUM/DIFFUSE).
You can set the desired level using button G. The
MEDIUM level is recommended.
