Particular situations
In certain situations (e.g. starting the engine), the   parking   brake   can   automatically   alter   its  
f

orce.   This   is   normal   operation.
To
  advance   your   vehicle   a   few   centimetres  
w

ithout   starting   the   engine,   but   with   the   ignition  
o

n,   press   on   the   brake   pedal   and   release   the  
p

arking   brake   by pulling then releasing the
control lever A .
  The   full   release   of   the   parking  
b

rake   is   confirmed   by   the   warning   lamps   in  
t

he control lever A   and   in   the   instrument   panel  
g

oing   off   and   display   of   the   message   "Parking  
b

rake   off ".
Emergency braking
In the event of failure of the electronic
stability   control   system,   signalled   by t

he   illumination   of   this   warning   lamp,
 b

raking   stability   is   then   not   guaranteed.
