so
 
improves

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
