RECOMMENDATIONS FOR VENTILA TION AND AIR CONDITIONING
In order for  these  systems  to  be  fully  ef fective,  follow  the  operation  and  maintenance
  guidelines   below:
F
 
T
o  
obtain
 
an
 
even
 
air
 
distribution,
 
take
 
care
 
not
 
to
 
obstruct

s  
located
 
at
 
the
 
base
 
of
 
the
 
windscreen,
 
the
 
nozzles,
 
the
 
vents

 
and
 
the
 
air
 
outlets,
 
as
 
well
 
as
 
the
 
air
 
extractor
 
located
 
in
 
the
 
boot.
F

 
Do
 
not
 
cover
 
the
 
sunshine
 
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
 
towing
 
the
 
maximum
 
load
 
on
 
a
 
steep
 
gradient
 
in
 
high
 
temperatures,
 
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
 very
 high,  first  ventilate  the  pas -
senger  compartment  for  a  few  moments.
Put
 
the
 
air
 
flow

at
 
a
 
set

ting
 
high
 
enough
 
to
 
quickly
 
change

 
the
 
air
 
in
 
the
 
passenger
 
compartment.
The

 
air
 
conditioning
 
system
 
does

 
not
 
contain
 
chlorine
 
and
 
does

 
not
 
present
 
any
 
danger
 
to
 
the

  ozone   layer.
The
 
condensation
 
created
 
by
 
the

 
air
 
conditioning
 
results
 
in
 
a
 
discharge

 
of
 
water
 
under
 
the
 
ve
-
hicle
  which   is   perfectly   normal.
Stop & Start
The
 
heating
 
and
 
air
 
conditioning
 
systems
 
only
 
work
 
when
 
the
 
engine
 
is
 
running.

 
T
o  
maintain
 
a
 
comfortable
 
temperature

you
 
can
