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.

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

Engine oil change
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

nd   emission   control   system,   never   use  
a

dditives   in   the   engine   oil. The
  brake   fluid   level   should   be   close  t
o   the   "MA X"   mark.   If   it   is   not,   check  t
he   brake   pad   wear.
Brake fluid level
Changing the fluid
Refer to the manufacturer's service schedule f
or   details   of   the   interval   for   this   operation.
Fluid specification
The brake fluid must conform to the manufacturer's r ecommendations.

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   by
 t

wo
 
turns
 
to   allow   the   pressure   to   drop.   When   the
 p

ressure
 
has   dropped,   remove   the   cap   and   top
 u

p
 
the
 
level.
Changing the coolant
The coolant does not have to be replaced at routine services.
The cooling fan may star t after switching
off the engine: take care with ar ticles and
clothing that might be caught by the fan
blades. When   the   engine   is   warm,   the   temperature   of  
t

he   coolant   is   regulated   by   the   fan.
Fluid specification
The coolant must conform to the ma
nufacturer's r ecommendations.
Fluid specification
For optimum cleaning and to avoid freezing, this   fluid   must   not   be   topped   up   or   replaced

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

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

ave   an   adverse   effect   on   the   per formance  
o

f   the   air   conditioning   system   and   generate
