Climatronic (automatic air conditioning) Description The Climatronic system is an automatic heating, fresh air and cool-
ing system which provides optimal comfort for the occupants of the
car.
The Climatronic maintains fully automatically a convenience temperature. This is
achieved by automatically varying the temperature of the outflowing air, the
blower stages and the air distribution. The system also takes into account sun-
light which eliminates the need to alter the settings manually. The automatic
mode
⇒
page 92 ensures maximum well-being of the occupants at all times of
the year.
Description of Climatronic system
The cooling operates only if the following conditions are met:
● engine running,
● outside temperature above approx. +2 °C,
● AC switched on.
The AC compressor is switched off at a high coolant temperature in order to pro-
vide cooling at a high load of the engine.
Recommended setting for all periods of the year:
● Set the desired temperature, we recommend 22 °C.
● Press the button AUTO
⇒ fig. 95 .
● Move the air outlet vents 3 and 4 so that the air flow is directed slightly up-
wards. Note
● We recommend that you have Climatronic cleaned by a specialist garage once
every year.
● On vehicles equipped with a factory-fitted radio or radio navigation system,
the information of the Climatronic is also shown on the display. This function can
be switched off, see operating instructions of the radio or the radio navigation
system.
