Notes on using THERMATIC automatic
climate control

dations on optimum operation of THERMATIC
automatic climate control.
Activate climate control using the à and
R
Á buttons. The indicator lamps in the
à and Á buttons light up.
Set the temperature to 22 †.
R
Only use the demisting function briefly,
R
until the windscreen is clear again.
Only use the air-recirculation mode briefly,

e.g. if there are unpleasant outside odours
or when in a tunnel. The windows could
otherwise mist up as, in air-recirculation
mode, no fresh air is drawn into the vehicle.
Use the ZONE function to adopt the tem-

perature settings on the driver's side for
the front-passenger side as well. The indi-
cator lamp in the á button goes out.
