Load reduction mode
System which manages the use of certain functions   according   to   the   level   of   charge  
r

emaining   in   the   battery.
When
  the   vehicle   is   being   driven,   the   load  
r

eduction   function   temporarily   deactivates  
c

ertain   functions,   such   as   the   air   conditioning,  
t

he   heated   rear   screen...
The
  deactivated   functions   are   reactivated  
a

utomatically   as   soon   as   conditions   permit.System
  which   manages   the   duration   of   use   of  c
ertain functions to conserve a sufficient level
of
  charge   in   the   battery.
After
  the   engine   has   stopped,   you   can  
s

till   use   functions   such   as   the   audio   and  
t

elematics   system, windscreen   wipers,   dipped  
b

eam   headlamps, courtesy   lamps,   etc.   for  
a

  maximum   combined   duration   of   about

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.

and
  B.
Oil grade
Before topping-up the oil or changing the oil, c

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

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.
Particle filter (Diesel)
The start of saturation of the
particle  filter   is   indicated   by   the  
f

ixed   illumination   of   this   warning  
l

amp   accompanied   by   a   warning  
m

essage.
As
 
soon
 
as
  the   traffic   conditions   permit,  
r

egenerate
 
the   filter   by   driving   at   a   speed   of   at  
l

east
 
40
 
mph   (60   km/h)   until   the   warning   lamp  
g

oes
 
off.
If
 
the
 
warning   lamp   stays   on,   this   indicates   a  
l

ow
 
additive   level.
Refer
 
to
 
the   "Diesel   additive   level"   section.
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,  
y

ou
 
may,   in   exceptional   circumstances,  
n

otice   the   emission   of   water   vapour   at  
t

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. 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:   your  
v

ehicle
 
becomes
 
polluting.
In
 
the
 
event
 
of
 
a
 
confirmed   fault  
w

ith
 
the
 
SCR
 
system,   you   must   go  
t

o
 
a
 
CITROËN
 
dealer   or   a   qualified  
w

orkshop
 
as
 
soon   as   possible:   after   a  
r

unning
 
distance
 
of   650   miles  
(1
 
100
 
km),
 
a
 
system   will   be   triggered  
a

utomatically
 
to
 
prevent   engine   starting.
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.

In the event of the risk of non-starting related to a lack of AdBlue®
Remaining range between 350 and 1500 miles (600 and 2 400 km)
When switching on the ignition, the U REA warning   lamp   comes   on,   accompanied
