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.

Breakdown related to a lack of AdBlue® additive
When switching on the ignition, the SERVICE warning   lamp   comes   on   and   the   UREA  
w

When
  driving,   this   display   appears   every

Topping-up the AdBlue® additive
Precautions in use
Use only AdBlue® additive that meets the I
SO 22241
 
standard.
The
 
supply
 
in
 
a
 
non-drip   bottle   simplifies  
t

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

allon)
 
bottles
 
from   a   CITROËN dealer   or   a  
q

ualified
 w

orkshop.
Keep
 
AdBlue
® out of the reach of
children,
 
in
 
its
  original   bottle.
Never
 
transfer   AdBlue
® to another
container:
 
it
 
would
 
loose   its   purity. Never
  dilute   the   additive   with   water.
Never   pour   the   additive   into   the   Diesel  
f

uel   tank.
Never   top-up   from   an   AdBlue®
dispenser
 
reserved
 
for
 
heavy
 
goods  
v

ehicles.
Filling
 
the
 
AdBlue
® tank is an operation i

in
 
every
 
routine   service   on   your  
v

ehicle
 
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. The
  AdBlue
® additive is an urea-based s
olution.
 
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

ammonia
 
cannot   be   excluded:   do   not   inhale

CITROËN Localised Assistance Call
When the ignition is switched on, the green LED  comes   on   for   3   seconds   indicating that

  the   system   is   operating   correctly.
If
  the   orange   LED   flashes:   there   is   a  
system

  fault.
If
  the   orange   LED   is   on   continuously:   the  
backup

  battery   must   be   replaced.
In
  either   case,   contact   a   CITROËN   dealer.
Pressing
 
this

again
 
immediately   cancels   the   request.
The

Operation of the system
The green LED remains on (without flashing) when communication is established.
  It   goes   off   at   the   end   of   communication.
This
  call   is   dealt   with   by   the  
C
ITR o Ë n   Localised   Emergency   Call   centre  
which

  receives   locating   information   from   the   vehicle   and   can   send   a  
detailed

  alert   to   the   appropriate   emergency   services.   In   countries   in  
which

  the   team   is   not   operational,   or   when   the   locating   service   has  
been

  expressly   declined,   the   call   is   dealt   with   directly   by   the   emergency  
services

  (112)   without   the   vehicle   location.
If
  an   impact   is   detected   by   the   airbag   control   unit,   and  
independently

  of   the   deployment   of   any   airbags,   an   emergency   call  
is

  made   automatically.
