AdBlue® additive and SCR system
f
or
Â
BlueHDi  Diesel  engines
To assure respect for the environment and c
onformity  with  the  new  Euro  6  emissions Â
s
tandard,  without  adversely  affecting  the Â
p
er formance  or  fuel  consumption  of  Diesel Â
e
ngines,  CITROËN  has  taken  the  decision  to Â
e
quip  its  vehicles  with  an  effective  system  that Â
a
ssociates  SCR  (Selective  Catalytic  Reduction) Â
w
ith  a  particle  filter  (FAP)  for  the  treatment  of Â
e
xhaust  gases.
Presentation of the SCR system
Using an additive called AdBlue® containing u
rea, a catalytic converter turns up to
85%Â of
Â
nitrous
Â
oxides
Â
(NOx)
Â
into
 nitrogen Â
a
nd
Â
water,
Â
which
Â
are
Â
harmless
Â
to  health  and Â
t
he environment. The AdBlue
® additive is held in a special
tank
Â
located
 under  the  boot  at  the  rear  of Â
t
he
Â
vehicle.
Â
It  has  a  capacity  of  17  litres:  this Â
p
rovides
Â
a
Â
driving  range  of  about  12  500  miles Â
(
20
Â
000
Â
km),
 after  which  an  alert  is  triggered Â
w
arning
Â
you
Â
when  the  reserve  remaining  is Â
e
nough
Â
for
Â
just  1  500  miles  (2  400  km).
During
Â
each
 scheduled  service  of  your  vehicle Â
b
y
Â
a
Â
CITROËN  dealer  or  a  qualified  workshop, Â
t
he AdBlue
® additive tank is refilled in order to a
llow
Â
normal  operation  of  the  SCR  system.
If
Â
the
Â
estimated  mileage  between  two  services Â
i
s
Â
greater
Â
than  12  500  miles  (20  000  km),  we Â
r
ecommend
 that  you  go  to  a  CITROËN  dealer Â
o
r
Â
a
Â
qualified  workshop  to  have  the  necessary Â
t
op-up
Â
carried  out. Once the AdBlue
® tank is empty, a
Â
system
Â
required
 by  regulations Â
p
revents
Â
starting
Â
of  the  engine.
If the SCR
is faulty, the level of
emissions
Â
from
Â
your  vehicle  will  no Â
l
onger
Â
meet
Â
the
Â
Euro  6  standard:  you Â
v
ehicle
Â
becomes
Â
polluting.
In
Â
the
Â
event
Â
of
Â
a
Â
confirmed  fault Â
w
ith
Â
the
Â
SCR
Â
system,  you  must  go Â
t
o
Â
a
Â
CITROËN
Â
dealer  or  a  qualified Â
w
orkshop
Â
as
Â
soon  as  possible:  after Â
a
Â
running
Â
distance  of  650  miles Â
(
1Â 100
Â
km),
Â
a
Â
system  will  be  triggered Â
a
utomatically
Â
to
Â
prevent  engine Â
s
tarting.
