Checking levels
Take care when working under the bonnet,   as   certain   areas   of   the   engine  
m

ay   be   extremely   hot   (risk   of   burns)  
a

nd   the   cooling   fan   could   start   at   any  
t

ime   (even   with   the   ignition   off).
Engine oil level
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.
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.
If 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.
A = MA X
B = MIN
To
  ensure   that   the   reading   is   correct,  
y

our   vehicle   must   be   parked   on   a   level  
s

ur face   with   the   engine   having   been   off  
f

or   more   than   30   minutes.
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).The
  location   of   the   dipstick   is   shown   in   the  
c

orresponding   underbonnet   layout   view.
F
 
T

r

emove   it   completely.
F
 
W

n

on-fluffy   cloth.
F
 
R
efit   the   dipstick   and   push   fully   down,   then  
p

ull   it   out   again   to   make   the   visual   check:  
t

he   correct   level   is   between   the   marks   A
and B .
Oil grade
Before topping-up the oil or changing the oil, c
heck   that   the   oil   is   the   correct   grade   for   your  
e

ngine   and   conforms   to   the   manufacturer's  
r

ecommendations.

In
  order   to   maintain   the   reliability   of   the   engine  
a

nd   emission   control   system,   never   use  
a

Brake fluid level
Changing the fluid
Refer to the manufacturer's service schedule f
or   details   of   the   interval   for   this   operation.

Checks
12 V battery
The battery does not require any maintenance.
H owever,   check   regularly   that   the   terminals  
a

re   correctly   tightened   (versions   without   quick  
r

elease   terminals)   and   that   the   connections  
a

re   clean.Refer to the manufacturer's service schedule for details of the
replacement
  intervals   for   these  
c

omponents.
Air filter and passenger compartment filter
Replace the oil filter each time the e ngine   oil   is   changed.
Refer
  to   the   manufacturer's  
s

ervice schedule for details of
the
  replacement   interval   for   this  
c

omponent.
Oil filter
Unless other wise indicated, check these components in accordance with the manufacturer's service schedule and according to your engine.
O ther 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  
h

ave   an   adverse   effect   on   the   per formance  
o

f   the   air   conditioning   system   and   generate  
u

ndesirable
 o
dours.
Particle filter (Diesel)
The start of saturation of the
particle filter is indicated by the
fixed  illumination   of   this   warning  
l

amp   accompanied   by   a   warning  
m

essage.
As
 
soon
 
as
  the   traffic   conditions   permit,

In the event of a fault with the SCR emissions control system
In the event of the detection
of a faultDuring an authorised driving phase (between
650 miles and 0 miles) (1 100 km and 0 km)
A
  system   that   prevents   engine   starting   is   activated   automatically   from   650   miles   (1   100   km)   after   confirmation   of   a   fault   with   the   SCR   emissions  
c

ontrol   system.   Have   the   system   checked   by   a   CITROËN   dealer   or   a   qualified   workshop   as   soon   as   possible.
If   it   is   a   temporary   fault,   the   alert  
d

isappears   during   the   next   journey,

ault".
The
  alert   is   triggered   when   driving   when   the  
f

ault   is   detected   for   the   first   time,   then   when  
s

witching   on   the   ignition   for   subsequent  
j

ourneys,   while   the   fault   persists. If
  a   fault   with   the   SCR   system   is   confirmed   (after
 3

While
  driving,   the   message   is   displayed   every
