Checking levels
The check is carried out either when the   ignition   is   switched   on   using   the  
o

il   level   indicator   in   the   instrument  
p

anel   for   vehicles   so   equipped,   or  
u

sing   the   dipstick.
Engine oil level
Checking using
the dipstick
Check all of these levels regularly, in line with the manufacturer's service schedule. Top them up if necessary, unless other wise indicated.
I f   a   level   drops   significantly,   have   the   corresponding   system   checked   by   a   CITROËN   dealer   or   a   qualified   workshop.
It
  is   normal   to   top   up   the   oil   level   between  
t

wo   services   (or   oil   changes).   CITROËN  
r

ecommends   that   you   check   the   level,   and   top  
u

p   if   necessary,   every   3   000   miles   (5   000   kms).A
  =   MA X
B
  =   MINIf
  you   find   that   the   level   is   above   the   A   mark   or  
belo

w the B   mark,   do not star t the engine.
-
 
I
f   the   level   is   above   the   MAX
 
mark   (risk  
o

f   damage   to   the   engine),   contact   a  
C

ITROËN   dealer   or   a   qualified   workshop.
-
 
I
f   the   level   is   below   the   MIN
 
mark,   you  
m

ust   top   up   the   engine   oil.
Oil grade
Before topping-up the oil or changing the oil, check   that   the   oil   is   the   correct   grade   for   your  
e

ngine   and   conforms   to   the   manufacturer's  
r

ecommendations.
Take

Refer to the manufacturer's service schedule for   details   of   the   interval   for   this   operation.
In
  order   to   maintain   the   reliability   of   the   engine  
a

Brake fluid level
Changing the fluid
Refer to the manufacturer's service schedule for   details   of   the   interval   for   this   operation.
Fluid specification
The brake fluid must conform to the manufacturer's r ecommendations.
The
  brake   fluid   level   should   be   close  
t

o   the   "MA X"   mark.   If   it   is   not,   check  
t

Power steering
fluid level
The power steering fluid level should b

Specification of the fluid
To ensure optimum cleaning and to avoid freezing,   the   fluid   should   never   be   topped   up   or r

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 urea, a
 
catalytic
 
converter
 
turns
 
up
 
to
 
85%   of   nitrous o

xides
 
(NOx)
 
into
 
nitrogen
 
and
 
water,   which   are
 h

armless
 
to
 
health
 
and
 
the
 
environment.
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   prevents  
s

tarting
 
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

as
 
soon   as   possible:   after  
a

 
running
 
distance   of   650   miles  
(

1 100

a
