In the event of a fault with the SCR emissions control system
If it is a temporary fault, the alert disappears   during   the   next   journey,  
a

fter   self-diagnosis   of   the   SCR   system.
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.
In the event of the detection of a fault
du
ring an authorised driving phase (between
650 miles and 0 miles) (1 100 km and 0 km)
The
 
UREA,   SERVICE   and   diagnostic   warning  
l

amps
  comes   on,   accompanied   by   an   audible  
s

ignal
  and   the   display   of   the   message  
"

Emissions
 f
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

0   miles   (50   km)   covered   with   the   permanent
 d

isplay   of   the   message   signalling   a   fault),   the
 S

ERVICE   and   engine   diagnostic   warning   lamps
 c

ome   on   and   the   UREA   warning   lamp   flashes,
 a

ccompanied   by   an   audible   signal   and   the
 d

isplay   of   a   message   (e.g.:   "Emissions   fault:
 S

tarting   prevented   in   150   miles")   indicating   the
 r

emaining   range   express   in   miles   or   kilometres.
While   driving,   the   message   is   displayed   every
 3

0   seconds   while   the   fault   with   the   SCR   system
 p
ersists.
The   alert   is   repeated   when   switching   on   the ig

nition.
You
  should   go   to   a   CITROËN   dealer   or   a
 q

ualified   workshop   as   soon   as   possible.
Other wise, you will not be able to restart your
engine. You
  have   exceeded   the   authorised  
d

riving   limit:   the   starting   prevention  
s

ystem   inhibits   engine   starting.
Every 
time  the  ignition  is  switched  on,  the  SERVICE a
nd   engine   diagnostic   warning   lamps   come   on   and t

he   UREA   warning   lamp   flashes,   accompanied   by
 a

n   audible   signal   and   the   display   of   the   message
 "

Emissions   fault:   Starting   prevented".

To
  be   able   to   start   the   engine,   you   must   call   on  
a

  CITROËN   dealer   or   a   qualified   workshop.

llow   the   engine   to   run   for   at   least  
3

0 minutes,   by   driving   or   with   the   vehicle  
s

tationary, so that the battery reaches an
adequate
  state   of   charge.

disconnecting the battery
In order to maintain an adequate state of   charge   for   starting   the   engine,   it   is  
r

ecommended   that   the   battery   be   disconnected  
i

f   the   vehicle   is   taken   out   of   service   for   a   long  
p

eriod.
Wait
  2   minutes   after   switching   off   the   ignition

s

ystem,   wipers,   lighting,   ...),
F
 
s
witch   off   the   ignition   and   wait   for  
f

our minutes.
Having
  exposed   the   battery,   it   is   only  
n

ecessary   to   disconnect   the   (+)   terminal.
Following reconnection of the
battery
After reconnecting the battery, switch on the ignition   and   wait   1   minute   before   starting   to  
a

llow   initialisation   of   the   electronic   systems.
However,
  if   minor   problems   persist   following  
t

his   operation,   contact   a   CITROËN   dealer   or   a  
q

ualified
 w
orkshop.
Referring
  to   the   corresponding   section,   you  
m

ust   yourself   reinitialise   or   reset   certain  
s

ystems,   such   as:
-
 
t
he   remote   control,
-
 
t
he   electric   windows,
-
 
t
he   date   and   time,
-

Quick release terminal
di
sconnecting the (+) terminal
F Raise the lever A fully to release the clamp  B.
Reconnecting the (+) terminal
F Position   the   open   clamp   B of the cable on
the   positive   post   (+)   of   the   battery.
F
 
P
ress   down   on   the   clamp   to   position   it  
c

orrectly   on   the   battery   post.
F
 
L
ock   the   clamp   by   lowering   the   lever   A. The
  Stop   &   Start   system   may   not   be  
o

perational   during   the   trip   following   the  
f

irst   engine   start.
In
  this   case,   the   system   will   only   be  
a

vailable   again   after   a   continuous  
p

eriod   of   immobilisation   of   the   vehicle,  
a

  period   which   depends   on   the   ambient  
t

emperature   and   the   state   of   charge   of  
t

he   battery   (up   to   about   8   hours).
Do
  not   force   the   lever   as   locking  
w

ill   not   be   possible   if   the   clamp   is

ot   positioned   correctly;   start   the  
p

rocedure   again.

Load reduction modeSystem 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.Energy economy modeSystem which manages the period of use of certain functions to conserve a sufficient level of c
harge   in   the   battery.
After
  the   engine   has   stopped,   you   can   still   use   functions   such   as   the   audio   equipment,   windscreen  
w

ipers,   dipped   beam   headlamps,   courtesy   lamps,   etc.   for   a   maximum   combined   period   of  
t

hirty minutes. This
  period   may   be   greatly   reduced   if  
t

he   battery   is   not   fully   charged.
A
  flat   battery   prevents   the   engine   from  
s

tarting.
If
  the   telephone   is   being   used   at   the  
s

ame   time,   it   will   be   interrupted   after  
10
 m

inutes.
Switching to economy mode
Once this period has elapsed, a message appears   in   the   screen   indicating   that   the  
v

ehicle   has   switched   to   economy   mode   and   the  
a

ctive   functions   are   put   on   standby.
Exiting economy mode
These functions are reactivated automatically the   next   time   the   vehicle   is   driven.
F
 
I
n   order   to   resume   the   use   of   these  
f

unctions   immediately,   start   the   engine   and  
l

et   it   run   for   a   few   minutes.
The
  time   available   to   you   will   then   be   double  
t

he   period   for   which   the   engine   is   left   running.  
H

owever,   this   period   will   always   be   between  
f

ive   and   thirty   minutes.
