The TRC and DSC systems offer increased   safety   in   normal   driving,   but  
s

hould   not   encourage   the   driver   to   take  
e

xtra   risks   or   drive   at   high   speed.
The correct operation of these
systems
  depends   on   observation   of  
t

he
 ma
nufacturer's
 r
ecommendations
 r

egarding   the   wheels   (tyres   and   rims),  
t

he   braking   components,   the   electronic  
c

omponents   and   the   assembly   and  
r

epair   procedures   used   by   CITROËN  
d

ealers.
After
  an   impact,   have   the   system  
c

hecked   by   a   CITROËN   dealer   or   a  
q

ualified
 w
orkshop.
Deactivation
In exceptional conditions (starting a vehicle which   is   bogged   down,   stuck   in   snow,   on   soft  
g

round...),   it   may   be   advisable   to   deactivate   the  
D

SC   and   TRC   systems,   so   that   the   wheels   can  
s

pin   freely   and   regain   grip.
Operating fault
However, it is recommended that these systems   be   reactivated   as   soon   as   possible.

P
ress   this   button   briefly.
This
  warning   lamp   comes   on:   the  
T

RC   system   no   longer   acts   on   the  
o

peration   of   the   engine.
Reactivation
The TRC and DSC control systems are reactivated   automatically   every   time   the   engine  
i

s   started. F
 
P
ress   the   button   again   to  
r

eactivate   it   manually. Illumination
  of   this   warning   lamp,  a
ccompanied   by   an   audible   signal,

Drive
  carefully   at   reduced   speed   and   contact  
a

  CITROËN   dealer   or   a   qualified   workshop   to  
h

ave   the   system   checked.

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

ay   be   extremely   hot   (risk   of   burns)   and  
t

he   cooling   fan   could   start   at   any   time  
(

even   with   the   ignition   off).
Engine oil level
The check of the oil level is carried out   with   the   dipstick,   located   under  
t

he   bonnet.   For   the   position   of   the  
d

ipstick,   refer   to   the   under-bonnet  
v

iew   on   a   previous   page.
Checking with 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.
To
  ensure   the   accuracy   of   the   reading,  
y

our   vehicle   must   be   on   a   level  
s

ur face,   with   the   engine   off   for   at   least  
3

0 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   km). If
  you   find   that   the   oil   level   is   above   the   A   mark  
o

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

f   engine   damage),   contact   a   CITROËN  
d

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

ust   top-up   the   engine   oil.
Refer
  to   the   under-bonnet   view   for   the   location  
o

f   the   dipstick   on   your   vehicle.
F
 
T

t

hen   pull   it   out   again   for   a   visual   check   of

t

wo   marks   A   and   B.

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  
r

eplacement   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  
t

he   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.
When
  carrying   out   any   operation   on   the  
12

f

or   details   of   the   precautions   to   be   taken   before  
s

General points
Lead-acid starter batteries
Batteries contain harmful substances such   as   sulphuric   acid   and   lead.
They
  must   be   disposed   of   in  
a

ccordance   with   regulations   and   must  
n

ot,   in   any   circumstances,   be   discarded  
w

ith   household   waste.
Take
  used   remote   control   batteries   and  
v

ehicle batteries to a special collection
point. Protect
  your   eyes   and   face   before  h
andling   the   battery.
All
  operations   on   the   battery   must   be  
c

arried   out   in   a   well   ventilated   area   and  
a

way   from   naked   flames   and   sources  
o

f   sparks,   so   as   to   avoid   the   risk   of  
e

xplosion   or   fire.
Wash
  your   hands   after wards.
