Misfuel prevention (Diesel)*Mechanical device which prevents filling the tank of a Diesel vehicle with petrol. It avoids the risk of engine damage that can result from filling with the wrong   fuel.
Located
  in   the   filler   neck,   the   misfuel   prevention   device   appears   when   the   filler   cap   is   removed.
Operation
When a petrol filler nozzle is introduced into the fuel   filler   neck   of   your   Diesel   vehicle,   it   comes  
i

nto   contact   with   the   flap.   The   system   remains  
c

losed   and   prevents   filling.
do n

ot persist but introduce a d
i
esel type
filler nozzle. It
  remains   possible   to   use   a   fuel   can   to  
f

ill   the   tank.
In   order   to   ensure   a   good   flow   of   fuel,  
d

o   not   place   the   nozzle   of   the   fuel   can  
i

n   direct   contact   with   the   flap   of   the  
m

Travelling abroad
As Diesel fuel pump nozzles may b
e   different   in   other   countries,   the  
p

resence   of   the   misfuel   prevention  
d

evice   may   make   refuelling   impossible.
Before
  travelling   abroad,   we  
r

ecommend   that   you   check   with   the  
C

ITROËN   dealer   network,   whether  
y

our vehicle is suitable for the fuel
pumps
  in   the   country   in   which   you   want  
t

o   travel.

Practical information

AdBlue® additive and SCR system
f
or
 
Blue
  HDi   Diesel   engines
To assure respect for the environment and c
onformity   with   the   new   Euro   6   emissions  
s

tandard,   without   adversely   affecting   the  
p

er formance   or   fuel   consumption   of   Diesel  
e

ngines,   CITROËN   has   taken   the   decision   to  
e

quip   its   vehicles   with   an   effective   system   that  
a

ssociates   SCR   (Selective   Catalytic   Reduction)  
w

ith   a   particle   filter   (FAP)   for   the   treatment   of  
e

xhaust   gases.
Presentation of the SCR system
Using an additive called AdBlue® containing u
rea, a catalytic converter turns up to
85% of
 
nitrous
 
oxides
 
(NOx)
 
into
  nitrogen  
a

nd
 
water,
 
which
 
are
 
harmless
 
to   health   and  
t

he environment. The
  AdBlue
® additive is held in a special t
ank
 
located
  under   the   boot   at   the   rear   of  
t

he
 
vehicle.
 
It   has   a   capacity   of   17   litres:   this  
p

rovides
 
a
 
driving   range   of   about   12   500   miles  
(

20
 
000
 
km),
  after   which   an   alert   is   triggered  
w

arning
 
you
 
when   the   reserve   remaining   is  
e

nough
 
for
 
just   1   500   miles   (2   400   km).
During
 
each
  scheduled   service   of   your   vehicle  
b

y
 
a
 
CITROËN   dealer   or   a   qualified   workshop,  
t

he
 
AdBlue
® additive tank is refilled in order to a
llow
 
normal   operation   of   the   SCR   system.
If
 
the
 
estimated   mileage   between   two   services  
i

s
 
greater
 
than   12   500   miles   (20   000   km),   we  
r

ecommend
  that   you   go   to   a   CITROËN   dealer  
o

r
 
a
 
qualified   workshop   to   have   the   necessary  
t

op-up
 
carried   out. Once
  the   AdBlue
® tank is empty, a
 
system
 
required
  by   regulations  
p

revents
 
starting
 
of   the   engine.
If the SCR

is faulty, the level of
emissions
 
from
 
your   vehicle   will   no  
l

onger
 
meet
 
the
 
Euro   6   standard:   you  
v

ehicle
 
becomes
 
polluting.
In
 
the
 
event
 
of
 
a
 
confirmed   fault  
w

ith
 
the
 
SCR
 
system,   you   must   go  
t

o
 
a
 
CITROËN
 
dealer   or   a   qualified  
w

orkshop
 
as
 
soon   as   possible:   after  
a

 
running
 
distance   of   650   miles  
(

1 100
 
km),
 
a
 
system   will   be   triggered  
a

utomatically
 
to
 
prevent   engine  
s

tarting.

199
Range indicators
When switching on the ignition, an indicator gives   an   estimate   of   the   distance   that   can  
b

e   travelled   with   your   vehicle   before   engine  
s

tarting   is   automatically   prevented,   once   the  
v

ehicle   starts   using   the   reserve   of   AdBlue
® or
after
 
a
 
fault
 
is
 
detected
 
with
 
the
 
SCR
 
system.
In
 
the
 
event
 
of
 
simultaneous
 
system
 
fault
 
and  
l

ow
 
AdBlue
® level, the shortest range is the one d
isplayed. The
  engine   start   prevention   system  
r

equired   by   regulations   is   activated  
a

utomatically   once   the   AdBlue
® tank i
s
 
empty.
In the event of the risk of non-starting related to a lack of AdBlue®
Range greater than 1 500 miles (2 400 km)
