and
 
the
 
air
 
outlets,
 
as
 
well
 
as

located
 
in
 
the

F

 
Do
 
not
 
cover

sensor
,  
located
 
on
 
the
 
dashboard;
 
this
 
is
 
used

  for   regulation   of   the   air   conditioning   system.
F
 
Operate
 
the
 
air
 
conditioning
 
system
 
for
 
at
 
least
 
5
 
to
 
10
 
minutes,
 
once
 
or
 
twice

  a   month   to   keep   it   in   perfect   working   order.
F
 
Ensure
 
that
 
the
 
passenger
 
compartment
 
filter
 
is
 
in
 
good
 
condition
 
and
 
have

  the   filter   elements   replaced   regularly.
  W

e  
recommend
 
the
 
use
 
of
 
a
 
combined
 
passenger
 
compartment
 
filter
.  
Thanks

 
to
 
its
 
special
 
active
 
additive,
 
it
 
contributes
 
to
 
the
 
purification
 
of
 
the

 
air
 
breathed
 
by
 
the
 
occupants
 
and
 
the
 
cleanliness
 
of
 
the
 
passenger
 
compartment

 
(reduction
 
of
 
allergic
 
symptoms,
 
bad
 
odours
 
and
 
greasy
 
deposits).
F

 
T
o  
ensure
 
correct
 
operation
 
of
 
the
 
air
 
conditioning
 
system,
 
you
 
are
 
also
 
advised

 
to
 
have
 
it
 
checked
 
regularly
 
as
 
recommended
 
in
 
the
 
mainte
-
nance
  and   warranty   guide.
F
 
If
 
the
 
system
 
does
 
not
 
produce
 
cold
 
air
,  
switch
 
it
 
of
f  
and
 
contact
 
a
 
CITROËN

  dealer   or   a   qualified   workshop.
When

a
 
steep

switching

 
of
f  
the
 
air
 
conditioning
 
increases
 
the
 
available
 
engine
 
power
 
and
 
so

  improves   the   towing   ability. If
 
after
 
an
 
extended
 
stop
 
in
 
sun

shine,  
the
 
interior
 
temperature
 
is

to
 
quickly
 
change

 
the
 
air
 
in
 
the

The

 
air
 
conditioning
 
system
 
does

 
not
 
contain
 
chlorine
 
and
 
does

 
not
 
present
 
any
 
danger
 
to
 
the

The
 
condensation
 
created
 
by

results
 
in
 
a
 
discharge

work
 
when
 
the

is
 
running.
