ADBLUE® ADDITIVE AND SCR SYSTEM
FOR
B
LUE HD I D IESEL
ENGINES
To assure  respect  for  the  environment  and
 conformity  with  the  new  Euro  6  
emissions

 
standard,
 
without
 
adversely
 
af

fecting  
the
 
performance
 
or
 
fuel
 
con
-
sumption
 
of
 
Diesel
 
engines,
 
CITROËN
 
has

 
taken
 
the
 
decision
 
to
 
equip
 
its
 
ve
-
hicles
 
with
 
an
 
ef
fective  
system
 
that
 
associates SCR (Selective Catalytic
Reduction)

 
with
 
a
 
particle
 
filter
 
(F
AP)  
for

  the   treatment   of   exhaust   gases.
Presentation of the SCR system
Using an additive  called  AdBlue® con-
taining
 urea,
 a
 catalytic
 converter
 turns  
up

 
to

 
85%

 
of

 
nitrous

 
oxides

 
(NOx)
 
into
 
nitrogen

 
and

 
water

,
 
which

 
are

 
harmless
 
to

 
health
 
and
 
the
 
environment. The
 
AdBlue® additive
 is  held  in  a  spe -
cial
 tank
 located  under  the  boot  at  the  
rear

 
of

 
the

 
vehicle.
 
It
 
has
 
a
 
capacity
 
of
 
17

 
litres:

 
this

 
provides
 
a
 
driving
 
range
 
of
 
about

 
12

 
500
 
miles
 
(20
 
000
 
km),
 
after
 
which

 
an

 
alert
 
is
 
triggered
 
warning
 
you
 
when

 
the

 
reserve
 
remaining
 
is
 
enough
 
for

 
just
 
1
 
500   miles   (2   400   km).
During
 
each

 
scheduled
 
service
 
of
 
your
 
vehicle

 
by

 
a

 
CITROËN
 
dealer
 
or
 
a
 
qual
-
ified
 
workshop,
 
the
 
AdBlue® additive  tank
 is
 refilled
 in
 order
 to
 allow  normal  
operation

 
of
 
the
 
SCR
 
system.
If
 
the

 
estimated

 
mileage

 
between
 
two
 
services

 
is

 
greater

 
than

 
12

 
500
 
miles
 
(20

 
000

 
km),

 
we

 
recommend

 
that
 
you
 
go

 
to

 
a

 
CITROËN

 
dealer

 
or

 
a
 
qualified
 
workshop

 
to

 
have

 
the

 
necessary
 
top-up
 
carried

 
out. Once
 
the
 
AdBlue® tank is
 empty ,  a
 system
 required
 by  regulations  
prevents

 
starting
 
of   the   engine.
If the SCR

is faulty, the level of
emissions
 
from

 
your
 
vehicle
 
will
 
no

 
longer

 
meet

 
the
 
Euro
 
6
 
stan
-
dard:
 
you

 
vehicle

 
becomes
 
pol
-
luting.
In
 
the

 
event

 
of

 
a

 
confirmed
 
fault
 
with

 
the

 
SCR

 
system,
 
you
 
must
 
go

 
to

 
a

 
CITROËN
 
dealer
 
or
 
a
 
qualified

 
workshop
 
as
 
soon
 
as
 
possible:

 
after

 
a

dis

tance
 
of

 
650

 
miles
 
(1

. Precautions in use
The
 AdBlue® additive is  an  urea-based  solution.
 This  liquid  is  non-flammable,  
colourless

 
and
 
odourless
 
(kept
 
in
 
a
 
cool
 
area).
In

 
the

 
event

 
of
 
contact
 
with
 
the
 
skin,
 
wash

 
the

 
af

fected  
area
 
with
 
soap
 
and
 
water

.
 
In

 
the
 
event
 
of
 
contact
 
with
 
the
 
eyes,

 
wash

 
(irrigate)
 
the
 
eyes
 
with
 
large
 
amounts

 
of

 
water
 
or
 
with
 
an
 
eye
 
wash
 
solution

 
for

 
at
 
least
 
15
 
minutes.
 
If
 
a
 
burning

 
sensation
 
or
 
irritation
 
persists,
 
get

 
medical
 
attention.
If
 
swallowed,
 
immediately
 
wash
 
out
 
the
 
mouth

 
with

 
clean
 
water
 
and
 
then
 
drink
 
plenty

 
of
 
water.
In
 
certain

 
conditions
 
(high

for

 
example),
 
the
 
risk
 
of

Ammonia

fect  
on
 
mucous
 
membranes

 
(eyes,   nose   and   throat).
Keep
 
AdBlue® out of the reach
of
 
children,
 
in
 
its   original   bottle.
Never
 
transfer
 
AdBlue® to an-
other
 container:
 it
 would  loose  
its

 
purity. Use
 
only
 
AdBlue® additive
 that  meets  the
 
ISO

standard.
Never

.
Never
 
pour

 
the
 
additive
 
into
 
the
 
Diesel

tank.
The supply  in  a  non-drip  bottle  simplifies  toping-up.
