Switching on
F Press the "A /C "
button, the button's
indicator lamp comes on.
The air conditioning does not operate
when the air flow adjustment control 2

a few moments. Then return to fresh
air intake.
The recirculation of interior air isolates the
passenger compartment from exterior odours
and smoke.
Return to exterior air intake as soon as possible

Comfort

Dual-zone digital air conditioningThe air conditioning system operates when the engine is running.
Automatic operation
1. Automatic comfort programme
We recommend the use of one of
the three AUTO modes available:
they provide optimised regulation of
the temperature in the passenger
compartment according to the comfort value
that you have chosen.
These three modes automatically adjust the
air flow, according to the desired setting, while
also maintaining the desired comfort value. F
P ress the "AUTO" button repeatedly:
-

a f
irst indicator lamp comes on; the
"light" setting mode is selected,
-

a s
econd indicator lamp comes on; the
"medium" setting mode is selected,
-

a t
hird indicator lamp comes on; the
"intense" mode setting is selected. When the engine is cold, the air
flow will reach its optimum level
progressively, taking account of the
weather and the desired comfort level
so as to avoid too great a distribution
of cold air.
On entering the vehicle, if the interior
temperature is much colder or warmer
than the comfort value, there is no
need to change the value displayed in
order to obtain the comfort required.
The system corrects the difference
in temperature automatically and as
quickly as possible.
This system is designed to operate effectively
in all seasons, with the windows closed.

The value indicated on the display

temperature in degrees Celsius or Fahrenheit.
F

T

urn control 2 or 3 to the left or to the right
respectively to decrease or increase this
value.
A setting around the value 21 provides
optimum comfort. However, depending on your
requirements, a setting between 18 and 24 is
normal.
You are advised to avoid a left / right setting
difference of more than 3.
