i Notes/tips
Activate climate control using the à and ¿
buttons. The indicator lamps above the à and
¿ buttons light up.
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 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.
