To assure respect for the environment and conformity with the new Euro 6
emissions
standard, without adversely
af
fecting the performance or fuel
consumption
of Diesel engines,
CITROËN
has taken the decision to
equip
its vehicles with an effective
system
that associates SCR (Selective
Catalytic Reduction) with a particle
filter
(FAP) for the treatment of exhaust
gases.
Presentation of the Scr system
Using an additive called adBlue®
containing urea, a catalytic converter
turns up to 85% of nitrous oxides
(
no
x) into nitrogen and water, which
are
harmless
to
health
and
the
environment.
The
a
dBlue
® additive is held in a
special
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).
d
uring each scheduled service of
your vehicle by a CITR
o Ë n dealer
or
a
qualified 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.
o
nce the a dBlue
® 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 standard: you
vehicle
becomes
polluting.
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
running
distance
of
650 miles
(1
100
km),
a
system
will be triggered
automatically
to
prevent engine
starting.
