Information about using automatic climate control
The following contains notes and recommendations on optimum use of automatic climate control.
R Activate climate control using the 
and
buttons. The indicator lamps in the
and
buttons light up.
• Set the temperature to 72 º F (22 º 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, since no fresh air is drawn into the vehicle in air-recirculation mode.
• 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.
