We recommend the use of one of t
he   three   AUTO   modes   available:  
t

hey   provide   optimised   regulation   of  
t

he   temperature   in   the    passenger  
c

ompartment   according   to   the  
c

omfort   value   that   you   have  
c

hosen. F

P
ress the "AUTO"
 
button   repeatedly:
-
 
a
  first   indicator   lamp   comes   on;   the  
"

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

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

intense"   mode   setting   is   selected.
The
 
air
 
conditioning   system   operates   when   the   engine   is   running.
1. Automatic comfort programme
This system is designed to operate effectively i
n   all   seasons,   with   the   windows   closed.When
  the   engine   is   cold,   the   air   flow   will  
r

each   its   optimum   level   progressively,  
t

aking   account   of   the   weather   and   the  
d

esired   comfort   level   so   as   to   avoid   too  
g

reat   a   distribution   of   cold   air.
On   entering   the   vehicle,   if   the   interior  
t

emperature   is   much   colder   or   warmer  
t

han   the   comfort   value,   there   is   no  
n

eed   to   change   the   value   displayed   in  
o

rder   to   obtain   the   comfort   required.  
T

he   system   corrects   the   difference  
i

n   temperature   automatically   and   as  
q

uickly   as   possible.
These
 
three
 
modes
 
automatically
 
adjust
 
the
 
a

ir
 
flow,
 
according
 
to
 
the
 
desired
 
setting,
 
while
 
a

lso
 
maintaining
 
the
 
desired
 
comfort
 
value.
