DIGITAL AIR CONDITIONING
The air conditioning system operates
with the engine running.
1. Automatic comfort regulation
A press on this button,
confi 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,
- passenger compartment tempe- rature, left and right,
- air distribution,
- air conditioning,
- automatic air recirculation. For this facility to operate, it is rec-
ommended that all air vents are kept
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 air fan
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.
A setting around 21 will provide
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 a difference of set-
tings of more than 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 operates automatically
to correct the difference in tempera-
ture 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
will then go off.

Resumption by the driver of the
adjustment of passenger com-
partment temperatures (for the
front and rear passengers)

A long press on the "AUTO" but-
ton cancels all personal settings,
including the passenger's tem-
perature, and returns the system
to automatic operation.

passengers present can still have
the benefi t of air circulation, even

you switch on the ignition as well
as when you stop the engine.

ing the air fan is displayed while the

several minutes. The duration
and availability of the function
depends on the state of charge
