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
 
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.
Stop & Start
The heating and air conditioning s ystems   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.

Dual-zone manual air conditioning with temperature regulation
The air conditioning system only works with the engine r unning.

  temperature   at   the   nozzles   and   vents  
i

s   regulated   by   the   system   according   to   the  
t

emperature   in   the   passenger   compartment

can
 
each
 
adjust
 t

The value indicated corresponds to a level of c
omfort   and   not   to   a   temperature   in   degrees   Celsius o

r   Fahrenheit   (depending   on   the   unit   selected).
A
  setting   of   around   21   provides   optimum   comfort.
 D

epending   on   your   requirements,   a   setting   between
 1

8   and   24   is   normal.
In addition, it is recommended that a difference between   left   and   right   of   more   than   3   should   be  
av

oided. The
  air   flow   symbol   (a   fan)   fills   progressively  
a

ccording   to   the   quantity   of   air   wanted.
By   reducing   the   air   flow   to   minimum,   you   are  
s

topping
 v
entilation.
Avoid   driving   for   too   long   without  
v

entilation   (risk   of   misting   and  d
eterioration   of   air   quality).

Driving recommendations
Observe the driving regulations and remain vigilant   whatever   the   traffic   conditions.
Pay
  close   attention   to   the   traffic   and   keep   your  
h

ands   on   the   wheel   so   that   you   are   ready   to  
r

eact   at   any   time   to   any   eventuality.
On
  a   long   journey,   a   break   every   two   hours   is  
s

trongly
 re
commended.
In
  difficult   weather,   drive   smoothly,   anticipate  
t

he   need   to   brake   and   increase   the   distance  
f

rom   other   vehicles.
Driving on flooded roads
We strongly advise against driving on flooded roads,   as   this   could   cause   serious   damage  
t

o   the   engine   or   gearbox,   as   well   as   to   the  
e

lectrical   systems   of   your   vehicle.If
  you   are   obliged   to   drive   through   water:
-  
c
heck   that   the   depth   of   water   does   not  
e

xceed   15   cm,   taking   account   of   waves  
t

hat   might   be   generated   by   other   users,
-  
d
eactivate   the   Stop   &   Start   system,
-  
d
rive   as   slowly   as   possible   without  
s

talling.   In   all   cases,   do   not   exceed   6   mph  (
10 km/h),
-  d o   not   stop   and   do   not   switch   off   the  
e

ngine.
On
  leaving   the   flooded   road,   as   soon   as  
c

ircumstances   allow,   make   several   light   brake  
a

pplications   to   dry   the   brake   discs   and   pads.
If
  in   doubt   on   the   state   of   your   vehicle,   contact  
a

  CITROËN   dealer   or   a   qualified   workshop.
Important!
Never drive with the parking brake applied   -   Risk   of   overheating   and  
d

amage   to   the   braking   system!
Risk
  of   fire!
As
  the   exhaust   system   of   your   vehicle  
i

s   very   hot,   even   several   minutes   after  
s

witching   off   the   engine,   do   not   park  
o

r   run   the   engine   over   areas   where  
in

flammable
 s
ubstances
 an
d
 m
aterials
 a

re   present:   grass,   leaves,   etc.
Never
  leave   a   vehicle   unsupervised  
w

ith   the   engine   running.   If   you   have  
t

o   leave   your   vehicle   with   the   engine  
r

unning,   apply   the   parking   brake  
a

nd   put   the   gearbox   into   neutral   or  
p

osition

N or P,
  depending   on   the   type  
o

f   gearbox.

When towing
Distribution of loads
F Distribute  the   load   in   the   trailer   so   that   the h
eaviest   items   are   as   close   as   possible   to t

he   axle   and   the   nose   weight   approaches   the
 m

aximum   permitted   without   exceeding   it.
Air
  density   decreases   with   altitude,   thus  
r

educing   engine   per formance.   Above  
1 0

00 metres,   the   maximum   towed   load   must  
b

e   reduced   by   10 %   for   every   1 000   metres   of  
al

titude.
Side wind
F Take   into   account   the   increased   sensitivity  t
o   side   wind.
For
  more   information   on   Weights
, refer
to   the   corresponding   section.
The   rear   parking   sensors   will   be  
d

eactivated   automatically   to   avoid   the  
a

udible   signal   if   a   genuine   CITROËN  
t

owbar   is   used.
Cooling
Towing a trailer on a slope increases the temperature   of   the   coolant.
As
  the   fan   is   electrically   controlled,   its   cooling  
c

apacity   is   not   dependent   on   the   engine   speed.
F
 
T
o   lower   the   engine   speed,   reduce   your  
s

peed.
The
  maximum   towed   load   on   a   long   incline  
d

epends   on   the   gradient   and   the   ambient  
t

emperature.
In
  all   cases,   keep   a   check   on   the   coolant  
t

emperature. F
 
I
f   the   warning   lamp   and   the  
S

TOP
 
warning   lamp   come   on,  
s

top   the   vehicle   and   switch   off  
t

he   engine   as   soon   as   possible.
Braking
Towing a trailer increases the braking distance.
T o   avoid   overheating   of   the   brakes,   the   use   of  
e

ngine   braking   is   recommended.
Ty r e s
F Check  the   tyre   pressures   of   the   towing  v
ehicle   and   of   the   trailer,   observing   the  
re

commended
 p
ressures.
Lighting
F Check  the   electrical   lighting   and   signalling  o
n   the   trailer   and   the   headlamp   beam  
h

eight   of   your   vehicle.
For
  more   information   on   Adjusting the
headlamp beam height , refer to the
corresponding
 s

ection.
