confi rmed by the display of
the A/C
warning lamp and

vides automatic control, at the tem-
perature selected, of all the following
5 functions:

- passenger compartment tem-
perature, left and right,

- air distribution,

- air conditioning,

- automatic air recirculation.

For this facility to operate, it is recom-
mended that all air vents are kept
open.

mode will prevent
the formation of mist inside the ve-
hicle in cold or humid weather.
When starting from cold, in order to

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.

more functions

functions 3, 4
