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 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 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  
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   starting.

Practical information

Freezing of the AdBlue® additive
The
 
AdBlue
® additive freezes at t
emperatures   below   around   -11°C.
The
 
SCR
 
system   includes   a   heater  
f

or
 
the
 
AdBlue
® tank, allowing you to c
ontinue
 
driving   in   very   cold   conditions.
Topping-up the AdBlue®
Filling the AdBlue® tank is an operation i
ncluded
 
in
 
every
 
routine   service   on   your  
v

ehicle
 
by
 
a
 
CITROËN   dealer   or   a   qualified  
w

orkshop.
Nevertheless,
 
given   the   capacity   of   the   tank,   it  
m

ay
 
be
 
necessary
  to   top-up   the   fluid   between  
s

ervices,
 
more
 
particularly   if   an   alert   (warning  
l

amps
 
and
 
a
 
message)   signals   the   requirement.
You
 
can
 
go
 
to
 
a
 
CITROËN   dealer   or   a   qualified  
w

orkshop.
If
 
you
 
envisage
 
topping-up   yourself,   please  
r

ead
 
the
 
following
 
warnings   carefully.Precautions in use
Use only AdBlue® fluid that meets the I
SO 22241
 
standard.
AdBlue® is a urea-based solution. This liquid is n
on-flammable,   colourless   and   odourless   (kept  
i

n
 
a
 
cool   area).
In
 
the
 
event   of   contact   with   the   skin,   wash  
t

he
 
affected   area   with   soap   and   water.   In   the  
e

vent
 
of
  contact   with   the   eyes,   wash   (irrigate)  
t

he
 
eyes   with   large   amounts   of   water   or   with  
a

n
 
eye
 
wash   solution   for   at   least   15   minutes.  
I

f
 
a
 
burning   sensation   or   irritation   persists,   get  
m

edical
  attention.
If
 
swallowed,   immediately   wash   out   the   mouth  
w

ith
 
clean   water   and   then   drink   plenty   of   water.
In
 
certain   conditions   (high   ambient  
t

emperature,   for   example),   the   risk   of   release   of  
a

mmonia   cannot   be   excluded:   do   not   inhale   the  
f

luid.
 
Ammonia   vapour   has   an   irritant   effect   on  
m

ucous
  membranes   (eyes,   nose   and   throat).The
  supply   in   a   non-drip   bottle   simplifies  
t

opping-up.   You   can   obtain   1.89   litre   (half   a   US  
g

allon)   bottles   from   a   CITROËN dealer   or   a  
q

ualified
 w
orkshop.
Never
  dilute   AdBlue
® with water.
N
ever
 
pour
 
AdBlue® into the Diesel fuel
tank.
Never
 
top-up
 
from
 
an   AdBlue
®
dispenser
 
reserved
 
for
 
heavy
 
goods  
v

ehicles.
Keep
 
AdBlue
® out of the reach of
children,
 
in
 
its
  original   bottle.
Never
 
transfer   AdBlue
® to another
container:
 
it
 
would
 
lose
  its   purity.
