In order for these systems to be fully effective, follow the operation and maintenance
guidelines below:
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
as
  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
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
qualified
 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
any
  danger   to   the   ozone   layer.
The condensation created by the air
conditioning
  results   in   a   discharge  
o

f water under the vehicle which is
per 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
in
  the   passenger   compartment,   you   can  
t

emporarily deactivate the Stop & Start
system.
For more information on Stop & Star t ,
refer
  to   the   corresponding   section.

When towing
Distribution of loads
F Distribute the load in the trailer so that the heaviest items are as close as possible to
the
  axle   and   the   nose   weight   approaches   the
 m

aximum   permitted   without   exceeding   it.
Air density decreases with altitude, thus
reducing
  engine   per formance.   Above  
1 0

00 metres,   the   maximum   towed   load   must  
b

e reduced by 10 % for every 1 000 metres of
altitude.
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
audible
  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
the
  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
height
  of   your   vehicle.
For more information on Adjusting the
headlamp beam height , refer to the
corresponding
 s

ection.

driver's
 
field
 
of
 
vision),
 
as
 
soon
 
as
 
this
 
p

resents
 
a
 
potential
 
danger. Sensors fitted in the front and rear bumpers
monitor
  the   blind   spots.
This
 
system
 
is

mirror   and   door   mirrors.   It   is   the   driver's  
r

esponsibility
 
to
 
constantly
 
check
 
the
 
traffic,
 
to   assess   the   distances   and   relative   speeds   of  
o

ther

In the event of a fault, this warning lamp flashes for a few moments in
the instrument panel, accompanied
by
  a   message.
Operating fault
Have it checked by a CITROËN dealer or a qualified w orkshop. The system may suffer temporary
interference in certain weather
conditions
  (rain,   hail...).
In   particular,   driving   on   a   wet   sur face  o
r   moving   from   a   dry   area   to   a   wet   area  c
an   cause   false   alerts   (for   example,   the  
p

resence   of   a   fog   of   water   droplets   in  
t

he   blind   spot   angle   is   interpreted   as   a  
v

ehicle).
In bad or wintry weather, ensure that
the sensors are not covered by mud, ice
or
  snow.
Take
  care   not   to   cover   the   warning   zone  
i

n the door mirrors or the detection
zones on the front and rear bumpers
with
  adhesive   labels   or   other   objects;  
t

hey may hamper the correct operation
of
  the   system.
High pressure jet wash
When
  washing   your   vehicle,   direct   the  
l

ance   at   least   30   cm   away   from   the  
sen

sors.In
  addition   to   the   fixed   warning   lamp   in   the   door  
m

irror on the side in question, a correction of
trajectory   will   be   felt   if   you   cross   a   lane   marking  w
ith the direction indicators on, to help you
avoid   a   collision.
Conditions for operation

This system indicates the proximity of an obstacle   (examples:   pedestrian,   vehicle,   tree,  
g

ate)   which   comes   within   the   field   of   detection  
o

f   sensors   located   in   the   bumper.
Certain
  types   of   obstacle   (examples:   stake,  
r

oadworks   cone)   detected   initially   will   no   longer  
b

e detected at the end of the manoeuvre, if
they
  are   located   in   blind   spots   in   the   sensors'  
f

ield
 o
f
 d
etection.
Parking sensors
This system cannot in any
circumstances replace the need for
vigilance   on   the   part   of   the   driver.The
  system   is   switched   on   by   engaging   reverse  
g

e a r.
This   is   confirmed   by   an   audible   signal.
The system is switched off when you come out
of   reverse   gear.
Audible assistance
The proximity information is given by an i
ntermittent   audible   signal,   the   frequency   of   which i

ncreases   as   the   vehicle   approaches   the   obstacle.
The
  sound   emitted   by   the   speaker   (right   or   left)
 i

ndicates   the   side   on   which   the   obstacle   is   located.
When the distance between the vehicle and
the
  obstacle   becomes   less   than   approximately
 t

hirty   centimetres,   the   audible   signal   becomes
 c

ontinuous.
Rear parking sensors
Visual assistance
This supplements the audible signal by d isplaying   bars   in   the   screen   or   the   instrument  
p

anel   which   move   progressively   nearer   to  
t

he   vehicle.   When   the   obstacle   is   near,   the  
"

Danger"   symbol   is   displayed.
