Coolant level
The coolant level should be close to   the   "MA X"   mark   but   should   never  
e

xceed   it.
In
 
addition,   as   the   cooling   system   is   pressurised,
 w

ait
 
at
 
least   one   hour   after   switching   off   the
 e

ngine
 
before   carrying   out   any   work.
To
 
avoid
 
any   risk   of   scalding,   unscrew   the   cap
 b

y
 
two
 
turns   to   allow   the   pressure   to   drop.   When
 t

he
 
pressure   has   dropped,   remove   the   cap   and

12 V battery
The battery does not require any maintenance.However, check that the terminals are clean and   correctly   tightened,   particularly   in   summer a

nd   winter.
Refer to the manufacturer's service   schedule   for   details   of   the  
r

eplacement   intervals   for   these

Air filter and passenger compartment filter
Replace the oil filter each time the e ngine   oil   is   changed.
Refer

s

ervice   schedule   for   details   of  
t

Oil filterThe presence of this label, in particular with
the   Stop   &   Start   system,   indicates   the   use   of  
a

  specific   12   V   lead-acid   battery   with   special  
t

echnology   and   specification.   The   involvement  
o

f   a   CITROËN   dealer   or   a   qualified   workshop  
i

s   essential   when   replacing   or   disconnecting  
t

he   battery.
Unless
  other wise   indicated,   check   these   components   in   accordance   with   the   manufacturer's   service   schedule   and   according   to   your   engine.
Other wise,   have   them   checked   by   a   CITROËN   dealer   or   a   qualified   workshop.
Depending   on   the   environment   (e.g.   dusty  
a

tmosphere)   and   the   use   of   the   vehicle  
(e.g.   city   driving),   replace them twice as often
if necessary .
A   clogged   passenger   compartment   filter   may

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

In

the
 
following
 
warnings   carefully.Precautions in use
Use only AdBlue® additive that meets t
he ISO 22241
 
standard.
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

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

f
 
ammonia
 
cannot   be   excluded:   do   not   inhale  
t

he
 
product.
 
Ammonia   vapour   has   en   irritant  
e

ffect
 
on
 
mucous   membranes   (eyes,   nose   and  
t

hroat). The
