Stop & Start
The heating and air conditioning systems   only   work   when   the   engine   is  
r

unning.
To
  maintain   a   comfortable   temperature  
i

n   the   passenger   compartment,   you   can  
t

emporarily   deactivate   the   Stop   &   Start  
s

ystem.
For
  more   information   on   Stop   &   Start,

In

  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
occupants
 
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.
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
 c
ompartment.
The   air   conditioning   system   does   not  
c

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

Automatic operation
We recommend the use of one of t
he   three   AUTO   modes   available:  
t

hey   provide   optimised   regulation   of  
t

he   temperature   in   the    passenger  
c

ompartment   according   to   the  
c

omfort   value   that   you   have  
c

hosen. F

P
ress the "AUTO"
 
button   repeatedly:
-
 
a
  first   indicator   lamp   comes   on;   the  
"

light"   setting   mode   is   selected,
-
 
a
  second   indicator   lamp   comes   on;   the  
"

medium"   setting   mode   is   selected,
-
 
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  
g

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

emperature   is   much   colder   or   warmer  
t

han   the   comfort   value,   there   is   no  
n

eed   to   change   the   value   displayed   in  
o

rder   to   obtain   the   comfort   required.  
T

he   system   corrects   the   difference  
i

n   temperature   automatically   and   as  
q

uickly   as   possible.
These
 
three
 
modes
 
automatically
 
adjust
 
the
 
a

ir
 
flow,
 
according
 
to
 
the
 
desired
 
setting,
 
while

lso
 
maintaining

comfort
 
value.

8. Air intake / Air recirculation
F Press this button for recirculation of the interior
air.
  The   indicator   lamp   in   the  
b

o

dours
 
and
  smoke.
F

A

s soon as possible, press this button
again
 
to   permit   the   intake   of   outside   air   and  
p

revent

i

ndicator   lamp   in   the   button   goes   off.
Avoid
  prolonged   operation   in   interior   air  
r

ecirculation   mode   (risk   of   misting   and  
d

eterioration   of   air   quality). For
  example,   while   you   are   away   from   the  
v

ehicle,   the   passengers   can   still   enjoy   some   air  
c

irculation   without   having   the   engine   running.
This
  function   is   available   after   switching   on   the  
i

gnition,   as   well   as   after   stopping   the   engine.
The period that the function is available
depends
  on   the   state   of   charge   of   the   battery.

t

he   function   is   confirmed   by   the   display   of  
t

wo dashes in the control screens and four
air
  flow   level   indicator   lamps.

a

ir   recirculation   mode   or   driving   for  
l

ong   periods   with   the   system   off   (risk   of  
m

isting   and   deterioration   of   air   quality).
This switch does not operate the air
conditioning,
  only   the   air   fan.
When the "REST" function is activated,
you
  cannot   modify   the   temperature,   air  
f
