In the event of a fault with the SCR emissions control system
In the event of the detection of a fault
The  AdBlue,   SERVICE   and   diagnostic  
w

arning   lamps   come   on,   accompanied   by   an  
a

udible   signal   and   the   display   of   the   message  
"

f

ault   is   detected   for   the   first   time,   then   when  
s

witching   on   the   ignition   for   subsequent  
j

ourneys,   while   the   fault   persists. During an authorised driving phase (between
650 miles and 0 miles) (1 100 km and 0 km)
If
  a   fault   with   the   SCR   system   is   confirmed  
(

after   30   miles   (50   km)   covered   with   the  
p

ermanent   display   of   the   message   signalling  
a

  fault),   the   SERVICE   and   engine   diagnostic  
w

(

e.g.   "Emissions   fault:   Starting   prevented   in  
1

50   miles")   indicating   the   remaining   range  
e

xpressed   in   miles   or   kilometres.
While
  driving,   the   message   is   displayed   every
 3

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.
For
  more   information   on   Stop & Star t,

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.
