AdBlue® additive and SCR system
f
or
 
BlueHDi   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 urea, a
 
catalytic
 
converter
 
turns
 
up
 
to
 
85%   of   nitrous o

xides
 
(NOx)
 
into
 
nitrogen
 
and
 
water,   which   are
 h

armless
 
to
 
health
 
and
 
the
 
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 s
ystem
 
required
 
by   regulations   prevents  
s

tarting
 
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   starting.
