use
 
of
 
a
 
combined
 
passenger
 
compartment
 
filter.
 
Thanks
 
to
 
its
 
s

pecial active additive, it contributes to the purification of the air breathed by the
occupants
 
and
 
the
 
cleanliness
 
of
 
the
 
passenger
 
compartment
 
(reduction
 
of
 
allergic
 
s

ymptoms,
 
bad
 
odours
 
and
 
greasy
 
deposits).

ensure
 
correct
 
operation

system,
 
you
 
are

the
 
system
 
does

When
 
towing
 
the
 
maximum
 
load
 
on
 
a
 
steep
 
gradient
 
in
 
high
 
temperatures,
 
switching
 
off
 
the
 a
ir
 
conditioning
 
increases
 
the
 
available
 
engine
 
power
 
and
 
so
 
improves
 
the
 
towing
 
ability. The condensation created by the air
conditioning
  results   in   a   discharge  
o

f water under the vehicle which is
per fectly   normal.
If   after   an   extended   stop   in   sunshine,  
t

he   interior   temperature   is   very  
h

igh,   first   ventilate   the   passenger  
c

ompartment   for   a   few   moments.
Put   the   air   flow   control   at   a   setting   high  
e

nough   to   quickly   change   the   air   in   the  
p

assenger

ompartment.
The   air   conditioning   system   does   not  
c

ontain chlorine and does not present
any   danger   to   the   ozone   layer.

-
 
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

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