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)
with
  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. 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:   your  
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  
r

unning
 
distance
 
of   650   miles  
(1
 
100
 
km),
 
a
 
system   will   be   triggered  
a

utomatically
 
to
 
prevent   engine   starting.
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.

In the event of a fault with the SCR emissions control system
In the event of the detection

Freezing of the AdBlue® additive
The AdBlue
® additive freezes at
temperatures   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® additive
Precautions in useFilling the AdBlue® tank is an operation i
ncluded in every routine service on your
vehicle
 
by
 
a
 
CITROËN   dealer   or   a   qualified  
w

orkshop.
Nevertheless,
 
given   the   capacity   of   the   tank,  
i

t
 
may
 
be
 
necessary   to   top-up   the   additive  
b

etween
 
services,
  more   particularly   if   an   alert  
(

warning
 
lamps
 
and   a   message)   signals   the  
r

equirement.
You
 
can
 
got
 
to
 
a
 
CITROËN   dealer   or   a   qualified  
w

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

ead
 
the
 
following
 
warnings   carefully. Keep AdBlue
® out of the reach of
children,
 
in
 
its
  original   bottle.
Never transfer AdBlue
® to another
container:
 
it
 
would
 
lose
  its   purity. Never
  dilute   the   additive   with   water.
Never pour the additive into the Diesel
fuel   tank.
Never   top-up   from   an   AdBlue®
dispenser
 
reserved
 
for
 
heavy
 
goods  
v

ehicles.
Use only AdBlue
® additive that meets the I
SO 22241
 
standard.
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.
The AdBlue® additive is an urea-based
solution.
 
This   liquid   is   non-flammable,  
c

olourless
 
and   odourless   (kept   in   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  
o

f
 
ammonia
 
cannot   be   excluded:   do   not   inhale  
t

he
 
product.
 
Ammonia   vapour   has   an   irritant  
e

ffect
 
on
 
mucous   membranes   (eyes,   nose   and  
t

hroat).
