AUTOMATIC AIR CONDITIONING 1 - Automatic operation
This system automatically regulates
temperature, air fl ow and air distribu-

according to the temperature selected
(for each side, right and left).
It provides an optimum level of comfort
regardless of the climatic conditions,

by permanent use of the automatic
air conditioning mode (press the AUTO
button ) and with all the vents open.
Having no airfl ow prevents the air con-
ditioning and the system in general
from working.

To prevent misting of the interior
of the vehicle in cold and damp
conditions, the use of AUTO
mode is recommended. 2 - Adjustment of
temperature on left
hand side
To set and display the de-
sired temperature, rotate
control 2 or 3 :
The display HI (high) corre-
sponds to a demand for maxi-
mum heating (above 27).
The display LO (low) cor-
responds to a demand for
maximum air conditioning
(below 15).

temperature on right
hand side
- To the left to lower the tempera- ture
- To the right to raise the tempera- ture
The difference between the tempera-
tures on the right and on the left can-
not be greater than 3 degrees.
A setting around 21 will provide a tem-
perature that is comfortable. Depending
on your requirements, an adjustment
between 18 and 24 is normal.
A press on this control,
confi rmed by the display of

"A/C" and "AUTO" , auto-
matically manages all the
5 following functions according to
the temperature chosen:
