  Air conditioning  
 To ensure that your system operates  
correctly, it is recommended to have 
it checked regularly.  
 Water  arising  from  condensation  
in  the  air  conditioning  drains  away 
through a hole provided for this pur-
pose. A pool of water may thus form 
under the vehicle when stationary.  
 To  keep  the  air  conditioning  com- 
pressor well sealed, it is essential to 
operate  the  air  conditioning  at  least 
once in every month.  
 Regardless  of  the  season,  the  air  
conditioning  is  useful,  since  it  re-
moves humidity and condensation. 
To  be  effective,  the  air  conditioning  
should  only  be  used  with  the  win-
dows closed. 
 If after a lengthy stop in bright sunlight 
the interior temperature is excessive, 
air  the  passenger  compartment  by 
opening  the  windows  for  a  few  mo-
ments, then close them again. 
 The air conditioning operates by using 
power from the engine. This results in 
a slight increase in fuel consumption.

nance  schedule  (see  "Maintenance 
Guide").  
  Air circulation  
   A i r   v e n t s   o n   t h e   fl   o o r   u n d e r n e a t h   t h e   
front  seats  provide  enhanced  heat-
ing  for  the  rear  seat  positions;  take 
care not to obstruct them.  
  Air vents  
 The air vents to the face have grilles  
and  thumbwheels  to  adjust  the  air 
 fl   o w    a n d    d i r e c t i o n    ( u p - d o w n ,    r i g h t -
left).  
 The  automatic  regulation  of  the  air 
conditioning,  inside  the  cabin,  uses 
a  number  of  sensors  (sunlight  sen-
sor,  outside  temperature  sensor...) 
that relieve you of the need to make 
frequent  adjustments  outside  the 
displayed temperature.  
 Be  careful  not  to  obstruct  the  sun- 
light  sensor,  located  on  the  dash-
board behind the instrument panel.

distribution 
   
     Press  on  button    2   to  make  the 
display  scroll  through  the  differ-
ent types of air distribution.  
 The  air  distribution  chosen 
is  shown  by  the  lighting  of 
the  corresponding  warning 
lamps on the display  2.  
  3.  Mode of adjustment  of temperature for  
the passenger 
   
     Press  on  button    3   to  have  inde-

 This control is for isolating disagree- 
able  odours  or  fumes  coming  from 
outside.  
   
     Press  on  button    4 ,  to  exclude 
entry of outside air. The warning  
lamp lights up.  
  This should be cancelled as soon  as  possible  to  permit  renewal  of

     Press  again  on  button    4 ,  to  de-
activate air recirculation.   
  5. Air conditioning  
 The  air  conditioning  can  only  oper- 
ate when the engine is running. The 
 a i r   b l o w e r   c o n t r o l   ( a d j u s t i n g   t h e   fl   o w

lamp lights up.  
    To  be  effective,    the  air  condi-
tioning should be operated   only-
   with the windows closed.  
 If  your  vehicle  is  not  equipped  with  
air  conditioning,  you  will  have  the 
same  control  panel  but  without  the 
 
A/C   button.
