Maintenance
In the event of a malfunction with the system, the "ECO OFF"   switch   warning   lamp   flashes,  
t

hen   comes   on   continuously.
Ha

ve   it   checked   by   a   CITROËN   dealer   or   a  
q

ualified
 w
orkshop.
Operating fault
This system requires a specific battery with   a   special   specification   and   technology  
(

reference numbers   available   from   a   CITROËN  
d

ealer   or   a   qualified   workshop).
Fitting
  a   battery   not   listed   by   CITROËN  
i

ntroduces   the   risk   of   malfunction   of   the  
s

ystem. Before
  doing   anything   under   the  
b

onnet,   deactivate   the   Stop   &   Start  
s

ystem   to   avoid   any   risk   of   injury  
r

esulting   from   automatic   operation   of  
S

TART   mode.
The   Stop   &   Start   system   makes   use  
o

f   advanced   technology.   All   work   on  
t

his   type   of   battery   must   be   done   only  
b

y   a   CITROËN   dealer   or   a   qualified  
w

orkshop.
In
 
the
 
event
 
of
 
a
 
fault
 
in
 
STOP
 
mode,
 
the
 v

ehicle
 
may
 
stall.
 
All
 
of
 
the
 
instrument
 p

anel
 
warning
 
lamps
 
come
 
on.
Depending
 
on
 
version,
 
an
 
alert

essage
 
may
 
also
 
be
 
displayed
 
asking
 
y

ou
 
to
 
put
 
the
 
gear
 
lever
 
into
 
position
 
N
and
 
put
 
your
 
foot
 
on
 
the
 
brake
 
pedal.
It is then necessary to switch off the
ignition,
 
then
 
restart
 
the
 
engine
 
using
 
t

he
 
key
 
or
 
the
 
"START/STOP"
 
button.
