Checking levels
Take care when working under the bonnet, as certain areas of the engine may be extremely hot (risk of burns) and the cooling fan could start at any   time   (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 
panel for vehicles so equipped, or 
using
  the   dipstick.Checking using the dipstick
The location of the dipstick is shown in the corresponding   underbonnet   layout   view.
F
 
T
 ake   the   dipstick   by   its   coloured   grip   and  
r
emove   it   completely.
F
 
W
 ipe   the   end   of   the   dipstick   using   a   clean  
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 .
It is normal to top-up the oil level between 
two
 
services
 
(or
 
oil
 
changes).
 
CITROËN
 
r
ecommends
 
that
 
you
 
check
 
the
 
level,
 
and
 
top-
up
 
if
 
necessary,
 
every
 
3
 
000
 
miles
 
(5
 
000
 
kms).
Check
 
all
 
of
 
these
 
levels
 
regularly,
 
in
 
line
 
with
 
the
 
manufacturer's   service   schedule.   Top   them   up   if   necessary,   unless   other wise   indicated.
If
 
a
 
level
 
drops
 
significantly,
 
have
 
the
 
corresponding   system   checked   by   a   CITROËN   dealer   or   a   qualified   workshop.
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. A = MA X
B = MIN
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

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

Fluid specification
The coolant must conform to the 
manufacturer's r ecommendations.
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.To p p i n g - u p
The reservoir must be topped-up without delay 
by
  a   CITROËN   dealer   or   a   qualified   workshop.
Diesel fuel additive level 
(Diesel with particle filter)
The additive reservoir low level is 
indicated  by   fixed   illumination   of   this  
w
arning   lamp,   accompanied   by   an  
a
udible   signal   and   a   message   that  
t
he particle filter additive level is 
too low.
The
 
warning   lamp   comes   on   when   the   ignition  
i
s
 
switched   on,   or   every   time   the   stalk   is  
o
perated,
  until   the   reservoir   is   refilled.
Next
 
time
  you   stop,   refill   the   screenwash   /

Screenwash/headlamp 
wash level low
In the case of vehicles fitted with 
headlamp washers, when the fluid 
reservoir low level is reached this 
warning
  lamp   comes   on   in   the
 in
strument panel, accompanied by an 
audible
  signal   and   a   message. Avoid
  prolonged   contact   of   used   oil   or  
f
luids   with   the   skin.
Most of these fluids are harmful to 
health
  or   indeed   very   corrosive.
Do not discard used oil or fluids into 
sewers
  or   onto   the   ground.

Checks
12 V battery
The battery does not require any 
maintenance.
However,  check   that   the   terminals  
a
re   clean   and   correctly   tightened,  
p
articularly   in   summer   and   winter.Refer
  to   the   manufacturer's  s
ervice schedule for details of the 
replacement intervals for these 
components.
Air filter and passenger compartment filter
Replace the oil filter each time the 
engine   oil   is   changed.
Refer
  to   the   manufacturer's  
s
ervice schedule for details of 
the replacement interval for this 
component.
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   technology   and
 s
pecification.
 T
he involvement of a CITROËN dealer 
or
  a   qualified   workshop   is   essential   when
 r
eplacing   or   disconnecting   the   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  
h
ave an adverse effect on the per formance 
of   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  
i
llumination   of   this   warning   lamp  
a
ccompanied   by   a   warning   message.
As soon as the traffic conditions permit, 
regenerate
  the   filter   by   driving   at   a  
s
peed   of   at   least   40   mph   (60   km/h)   until  
t
he
 
warning   lamp   goes   off.
If
 
the   warning   lamp   stays   on,   this  
i
ndicates   a   low   additive   level.
For more information on Checking  
levels  and the Diesel additive level in 
particular,
  refer   to   the   corresponding  
s
ection.
On a new vehicle, the first particle 
filter
  regeneration   operations   may   be  
a
ccompanied   by   a   "burning"   smell,  
w
hich   is   per fectly   normal.
Following
  prolonged   operation   of   the  
v
ehicle at very low speed or at idle, 
you
  may,   in   exceptional   circumstances,  
n
otice the emission of water vapour at 
the
 
exhaust   on   acceleration.   This   does  
n
ot affect the behaviour of the vehicle 
or
 
the   environment.
When
 
carrying
 
out
 
work
 
on
 
the
 
battery,
 
refer
 
t
o the " 12 V batter y " section for details of the 
precautions
 
to
 
be
 
taken
 
before
 
disconnecting
 
t
he
 
battery
 
and
 
following
 
its
 
reconnection.

Brake wear depends on the style of   driving,   particularly   in   the   case o
f vehicles used in town, over short 
distances.
  It   may   be   necessary   to   have
 t
he   condition   of   the   brakes   checked,
 e
ven   between   vehicle   services.
Brake pads
For information on checking brake disc wear, contact a CITROËN dealer 
or
  a   qualified   workshop.
Brake disc wear
Only use products recommended by 
CITROËN or products of equivalent 
quality
 an
d
 sp
 ecification.
In order to optimise the operation of 
units as important as those in the 
braking
  system,   CITROËN   selects   and  
o
ffers   very   specific   products.
After
  washing   the   vehicle,   dampness,  
o
r in wintry conditions, ice can form 
on
  the   brake   discs   and   pads:   braking  
e
fficiency   may   be   reduced.   Make   light  
b
rake   applications   to   dry   and   defrost  
t
he   brakes.
Electric parking brake
For more information, refer to the " Electric 
parking brake - Operating faults "
  section.
This system does not require any 
routine
  servicing.   However,   in   the  
e
vent of a problem, have the system 
checked   by   a   CITROËN   dealer   or   a  
q
ualified
 w
 orkshop.
Manual gearbox
The gearbox does not require any m
aintenance   (no   oil   change).
Refer
  to   the   manufacturer's   service  
s
chedule   for   the   checking   interval   for  
t
his
 c
 omponent.
Automatic gearbox
The gearbox does not require any maintenance   (no   oil   change).
Refer
  to   the   manufacturer's   service  
s
chedule for details of the level 
checking
  interval   for   this   component.
To
  avoid   damaging   the   electrical   units,  
n
ever use   a   high   pressure   jet   wash   in  
t
he   engine   compartment.
Unless
  there   is   a   leak   in   the   circuit,   a   drop   in  
t
he   brake   fluid   level   indicates   that   the   brake  
p
ads   are   worn.

AdBlue® additive and SCR system
for
 
BlueHDi   Diesel   engines
To assure respect for the environment and 
conformity with the new Euro 6 emissions 
standard,
  without   adversely   affecting   the  
p
er formance or fuel consumption of Diesel 
engines,
  CITROËN   has   taken   the   decision   to  
e
quip its vehicles with an effective system that 
associates SCR (Selective Catalytic Reduction) 
with a particle filter (FAP) for the treatment of 
exhaust
  gases.
Presentation of the SCR system
Using a fluid called AdBlue® containing urea, a c
atalytic
 
converter
 
turns
 
up
 
to   85%   of   nitrogen  
o
xides
 
(NOx)
 
into
 
nitrogen
 
and   water,   which   are  
h
armless
 
to
 
health
 
and
 
the
 
environment. The AdBlue
® additive is held in a special 
tank
 
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 
longer
 
meet
 
the
 
Euro   6   standard:   you  
v
ehicle
 
becomes
 
polluting.
In the event of a confirmed fault 
with
 
the
 
SCR
 
system,   you   must   go  
t
o a CITROËN dealer or a qualified 
workshop
 
as
 
soon   as   possible:   after  
a
 
running
 
distance   of   650   miles  
(
1 100
 
km),
 
a
 
system   will   be   triggered  
a
utomatically
 
to
 
prevent   engine   starting.
