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

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.

instruction,
 
etc)
 
a
 
continuous

Gear shift indicator*
Depending on the driving situation and your vehicle's   equipment,   the   system   may   advise  
y

ou   to   skip   one   (or   more)   gear(s).   You   can  
f

ollow   this   instruction   without   engaging   the  
i

ntermediate
 g
ears.
The
  gear   engagement   recommendations   must  
n

ot   be   considered   compulsory.   In   fact,   the  
c

onfiguration   of   the   road,   the   amount   of   traffic  
a

nd   safety   remain   determining   factors   when  
c

hoosing   the   best   gear.   Therefore,   the   driver  
r

emains   responsible   for   deciding   whether   or   not  
t

o   follow   the   advice   given   by   the   system.
This
  function   cannot   be   deactivated. -

The
  information   appears   in   the   instrument  
p

anel   in   the   form   of   an   arrow.
System
  which   reduces   fuel   consumption   by   recommending   the   most   appropriate   gear.
With   an   automatic   gearbox,   the   system   is   only  
a

* Depending
  on   engine.
On
  vehicle   fitted   with   a   manual   gearbox,  
t

he   arrow   may   be   accompanied   by   the   gear  
re

commended. The
  system   adapts   its   gear   change  
r

ecommendation   according   to   the  
d

riving   conditions   (slope,   load, ...)   and  
t

he   demands   of   the   driver   (power,
