Notes on using dual-zone automatic climate control
The following contains notes and recommendations on optimum use of dualzone automatic climate control.
• Activate climate control using the
and
buttons. The indicator lamps in the
and
buttons light up.
• Set the temperature to 72 °F (22 °C).
• Only use the "defrosting" function briefly until the windshield is clear
again.
• 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 ZONE function to adopt the
temperature settings on the driver's side
for the front-passenger side as well. The
indicator lamp in the 
button goes
out.
