In order for these systems to be fully effective, follow the operation and maintenance guidelines belo w:
F
 
T
o   obtain   an   even   air   distribution,   take   care   not   to   obstruct   the   exterior   air   intake   grilles  
l

ocated   at   the   base   of   the   windscreen,   the   nozzles,   the   vents   and   the   air   outlets,   as   well  
a

s   the   air   extractor   located   in   the   boot.
F
 
D
o   not   cover   the   sunshine   sensor,   located   on   the   dashboard;   this   is   used   for   regulation  
o

f   the   air   conditioning   system.
F
 
O
perate   the   air   conditioning   system   for   at   least   5   to   10   minutes,   once   or   twice   a   month  
t

o   keep   it   in   per fect   working   order.
F
 
E
nsure   that   the   passenger   compartment   filter   is   in   good   condition   and   have   the   filter  
e

lements   replaced   regularly.
  W

e   recommend   the   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  
o

ccupants   and   the   cleanliness   of   the   passenger   compartment   (reduction   of   allergic  
s

ymptoms,   bad   odours   and   greasy   deposits).
F
 
T
o   ensure   correct   operation   of   the   air   conditioning   system,   you   are   also   advised   to   have  
i

t   checked   regularly   as   recommended   in   the   maintenance   and   warranty   guide.
F
 
I
f   the   system   does   not   produce   cold   air,   switch   it   off   and   contact   a   CITROËN   dealer   or   a  
q

ualified
 w
orkshop.
Recommendations for ventilation and air conditioning
If after an extended stop in sunshine, the  i nterior  t emperature  i s  v ery  h igh,  f irst  
v

entilate   the   passenger   compartment   for  
a

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

nough   to   quickly   change   the   air   in   the  
p

assenger
 c
ompartment.
The
  air   conditioning   system   does   not  
c

ontain   chlorine   and   does   not   present  
a

ny   danger   to   the   ozone   layer.
The
  condensation   created   by   the   air  
c

onditioning   results   in   a   discharge  
o

f   water   under   the   vehicle   which   is  
p

er fectly   normal.
When

the
 
maximum
 
load

a
 
steep
 
gradient
 
in
 
high
 
temperatures,
 
switching
 
off
 
the
 
a

ir
 
conditioning
 
increases
 
the
 
available
 
engine
 
power
 
and
 
so
 
improves
 
the
 
towing
 
ability.
Stop & Start
The heating and air conditioning s ystems   only   work   when   the   engine   is
