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

 
running
 
dis
-
tance
 
of

 
650

 
miles
 
(1 
100  
km),
 
a

 
system

 
will

 
be

 
triggered
 
au
-
tomatically
 
to

 
prevent
 
engine
 
starting.

BATTERY
The battery  is  located  under  the   bonnet.
For   access   to   the   (+)   terminal:
F
 
release
 
the
 
bonnet
 
using
 
the
 
interior
 
lever

,  
then
 
the
 
exterior
 
safety
 
catch,
F

 
raise
 
the

and
 
secure
 
it
 
with
 
its stay

,
F

lift the plastic cover for access to
the (+)

  terminal.
Access to the battery
The presence of this label, in
particular with the Stop & Start
system, 
indicates
 
the
 
use
 
of
 
a 12 

V  
lead-acid
 
battery
 
with
 
spe
-
cial
 
technology
 
and
 
specification; the

 
involvement
 
of
 
a
 
CITROËN dealer

 
or
 
a
 
qualified
 
workshop
 
is essential

 
when
 
replacing
 
or
 
dis
-
connecting
  the   battery.
Procedure
 
for
 
starting
 
the
 
engine
  
using
 
another

 
battery
 
or
 
charging
 
a
 
dis
-
charged   battery.
After  
refitting
 
the
 
battery
,  
the
 
Stop

 
&
 
Start
 
system
 
will
 
only
 
be
 
active

 
after
 
a
 
continuous
 
period
 
of

 
immobilisation
 
of
 
the
 
vehicle,
 
a

 
period
 
which
 
depends
 
on
 
the
 
climatic

 
conditions
 
and
 
the
 
state
 
of

 
charge
 
of
 
the
 
battery
 
(up
 
to
 
about

  8   hours). First
 check  that  the  slave  battery  has
 a  nominal  voltage  of  12  V  
and

 
a
 
capacity
 
at
 
least
 
equal
 
to
 
that

  of   the   discharged   battery.
Do
 
not
 
try
 
to
 
start
 
the
 
engine
 
by
 
connecting

  a   battery   charger.
Do
 
not
 
disconnect
 
the
 
(+)

a

ll operations on the battery
must  be  carried  out  in  a  well  ventilated
 area  and  away  from  naked
 flames  and  sources  of  
sparks,

TOWING A TRAILER
We recommend  the  use  of  genu -
ine  CITROËN  towbars  and  their  
harnesses

 
that
 
have
 
been
 
tested
 
and

 
approved
 
from
 
the
 
design
 
stage

 
of
 
your
 
vehicle,
 
and
 
that
 
the

 
fitting
 
of
 
the
 
towbar
 
is
 
en
-
trusted
 
to
 
a
 
CITROËN
 
dealer
 
or
 
a

  qualified   workshop.
If
 
the
 
towbar
 
is
 
not
 
fitted
 
by
 
a
 
CITROËN

 
dealer
,  
it
 
must
 
still
 
be

 
fitted
 
in
 
accordance
 
with
 
the
 
vehicle

 
manufacturer's
 
instruc
-
tions.
Your
 
vehicle
 
is
 
primarily
 
designed
 
for
 
transporting

 
people
 
and
 
luggage,
 
but
 
it
 
may

 
also   be   used   for   towing   a   trailer.
Driving  
with
 
a
 
trailer
 
places
 
greater
 
de
-
mands
 
on
 
the
 
towing
 
vehicle
 
and
 
the
 
driver

  must   take   particular   care.
Driving advice
Distribution of loads

Distribute
 
the
 
load
 
in
 
the
 
trailer
 
so
 
that

 
the
 
heaviest
 
items
 
are
 
as
 
close
 
as

 
possible
 
to
 
the
 
axle
 
and
 
the
 
nose
 
weight

 
approaches
 
the
 
maximum
 
permitted

  without   exceeding   it.
Air
 
density
 
decreases
 
with
 
altitude,
 
thus
 
reducing

 
engine
 
performance.
 
Above
 


000  
metres,
 
the
 
maximum
 
towed
 
load
 
must

 
be
 
reduced
 
by
 
10 
%  
for
 
every
 
1 000

  metres   of   altitude.
Side wind
F
 
T
ake  
into
 
account
 
the
 
increased
 
sensitivity

  to   side   wind.
Cooling
Towing
 
a
 
trailer
 
on
 
a
 
slope
 
increases
 
the

  temperature   of   the   coolant.
As
 
the
 
fan
 
is
 
electrically
 
controlled,
 
its
 
cooling

 
capacity
 
is
 
not
 
dependent
 
on
 
the

  engine   speed.
F
 
T
o  
lower
 
the
 
engine
 
speed,
 
reduce
 
your

  speed. The
 
maximum
 
towed
 
load
 
on
 
a
 
long
 
in
-
cline  depends  on  the  gradient  and  the  ambient
  temperature.
In  all  cases,  keep  a  check  on  the  
 
coolant

  temperature.
F
 
If
 
the
 
warning
 
lamp
 
and
 
the
 
ST

OP  
warning
 
lamp
 
come
 
on,

 
stop
 
the
 
vehicle
 
and
 
switch

 
of
f  
the
 
engine
 
as
 
soon

  as   possible.
Braking
Towing
 
a
 
trailer
 
increases
 
the
 
braking
 
distance.
T

o  
avoid
 
overheating
 
of
 
the
 
brakes
 
on
 
a
 
long

 
mountain
 
type
 
of
 
descent,
 
the
 
use
 
of

  engine   braking   is   recommended.
Tyres
F
 
Check
 
the
 
tyre
 
pressures
 
of
 
the
 

towing

 
vehicle
 
and
 
of
 
the
 
trailer
,  
observing

 
the
 
recommended
 
pres
-
sures.
Lighting
F
 
Check
 
the
 
electrical
 
lighting
 
and
 
sig
-
nalling
  on   the   trailer.
Refer
 
to
 
the
 
"T
echnical  
data"
 
section
 
for
 
details

 
of
 
the
 
weights
 
and
 
towed
 
loads
 
which

  apply   to   your   vehicle.
The
 
rear
 
parking
 
sensors
 
will
 
be

 
deactivated
 
automatically
 
if
 
a

 
genuine
 
CITROËN
 
towbar
 
is
 
used.
