The design of the control panel and the
functions of Heatmatic are identical to that
of 2-zone Thermatic.
Exception: 2-zone Thermatic has the addi-
tional "A/C" function 9. 2-zone Thermatic combines a heating and
ventilation system with a cooling system.

g 119General notes
2-zone Thermatic*/Thermotronic* controls
the temperature and the humidity of the vehi-
cle interior and filters out undesirable sub-
stances from the air.
Heatmatic/2-zone Thermatic*/
Thermotronic* is only operational when the
engine is running. Optimum operation is only
achieved when you drive with the side win-
dows closed. i
Ventilate the vehicle for a brief period
during warm weather. This will speed up the
cooling process and the desired interior
temperature will be reached more quickly.
i The integrated filter filters out most par-
ticles of dust and completely filters out
pollen. A clogged filter reduces the amount
of air supplied to the vehicle interior. For
this reason, you should always observe the
interval for replacing the filter, which is specified in the Service Booklet. As it
depends on environmental conditions, e.g.
heavy air pollution, the interval may be
shorter than stated in the Service Booklet
. G
Risk of accident
Observe the settings recommended on the
following pages. The windows could other-
wise mist up. This may obstruct your vie w
of the traffic situation, thereby causing an
accident . Cont
