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 u
rea,

a

catalytic

converter

turns

up to 85%
o

f

nitrous

oxides

(NOx)

into

nitrogen and
w

ater,

which

are

harmless

to

health and the
e

nvironment. 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.
