AUTOMATIC AIR CONDITIONING
A. DRIVER’S CONTROL PANEL
1. Automatic comfort regulation
A press on this button, con-
fi rmed by the display of the

A/C warning lamp and of

AUTO on the screen, pro-
vides automatic control, at the tem-
perature selected, of all the following
5 functions:
- air fl ow,
- cabin temperature, on left hand side and right hand side,
- air distribution,
- air conditioning,
- automatic air recirculation. For this facility to operate, it is rec-
ommended to keep all the air vents
open.
Using the
AUTO mode will prevent
the formation of mist inside the vehicle
in cold or humid weather.
When starting from cold, in order to
avoid a rush of cold air, the blower
attains its optimum level progres-
sively. 2. Adjustment of temperature
To display the desired temperature,
press button:
-
– to decrease the temperature,
- + to increase the temperature.
An adjustment around 21 will pro-
vide an agreeable temperature level.
However, depending on your prefer-
ence, anything between 18 and 24
is quite normal.
For optimum comfort, it is recom-
mended to avoid an adjustment dif-
ference greater than 3 between right
and left.
Actual temperatures experienced in
the passenger compartment are de-
pendent on external factors and for
this reason might not be identical to
those displayed.
On entering the vehicle, the inside
temperature may be much colder (or
hotter) than would be comfortable. It
serves no purpose to alter the tem-
perature displayed in an attempt to
attain your preference more rapidly.
The system automatically uses its
maximum performance to make up
the difference in temperature as
soon as possible.

Manual resumption of one or
more functions
It is possible to adjust each of the
functions 3, 4 , 6 and 10 manually.
The display of the "AUTO" function

ton cancels all personal settings,
including the passenger's tem-
perature, and
