DIGITAL AIR CONDITIONING 1 - Automatic operation
This system automatically regulates
temperature, air fl ow and air distribu-
tion in the passenger compartment
according to the temperature selected
(for each side, right and left).
It provides an optimum level of comfort
regardless of the ambient 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
conditioning and the system in gen-
eral from working.

To prevent the formation of con-
densation inside 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).
3 - Adjustment of
temperature on right
hand side
- To the left to lower the temperature
-
To the right to raise the temperature
The difference between the tem-
peratures on the right and on the left
cannot be greater than 3 degrees.
A setting around 21 will provide a
temperature that is comfortable.
Depending on your requirements,
an adjustment between 18 and 24 is
normal.
A press on this control, con-
fi rmed by the display of
"A/C"
and "AUTO" , automatically
manages all the 5 following
functions according to the tempera-
ture chosen:
- Flow of air.
- Cabin temperature.
- Distribution of air.

 When you enter the vehicle, the
temperature inside the vehicle
may be much colder (or warmer)
than is comfortable. There is no
point in modifying the displayed
temperature to try to attain the
desired level of comfort. The
system operates automatically
to correct this temperature differ-
ence as rapidly as possible.

 When starting the engine from
cold, in order to avoid distributing
too much cold air, the blower will
attain its optimum level gradually.
