AdBlue® additive and SCR system
for
 
BlueHDi   Diesel   engines
To assure respect for the environment and
conformity with the new Euro 6 emissions
standard,
  without   adversely   affecting   the  
p

er formance or fuel consumption of Diesel
engines,
  CITROËN   has   taken   the   decision   to  
e

quip its vehicles with an effective system that
associates SCR (Selective Catalytic Reduction)
with a particle filter (FAP) for the treatment of
exhaust
  gases.
Presentation of the SCR system
Using a fluid called AdBlue® containing urea, a c
atalytic
 
converter
 
turns
 
up
 
to   85%   of   nitrogen  
o

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

armless
 
to
 
health
 
and
 
the
 
environment. The AdBlue
® additive is held in a special
tank
 
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  
p

revents
 
starting
 
of   the   engine.
If the SCR

is faulty, the level of
emissions from your vehicle will no
longer
 
meet
 
the
 
Euro   6   standard:   you  
v

ehicle
 
becomes
 
polluting.
In the event of a confirmed fault
with
 
the
 
SCR
 
system,   you   must   go  
t

o a CITROËN dealer or a qualified
workshop
 
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.
