Electronic stability control (ESC)
Definitions
Anti-lock braking system (ABS)
and electronic brake force
distribution (EBFD)
This system improves the stability and manoeuvrability   of   your   vehicle   when   braking  
a

nd   contributes   towards   improved   control   on  
c

orners, in particular on poor or slippery road
surfaces.
The
  ABS   prevents   wheel   lock   in   the   event   of  
em

ergency
 b
raking.
The
  EBFD   manages   the   braking   pressure  
w

heel   by   wheel.
Emergency braking assistance
(EBA)
In an emergency, this system enables you to reach   the   optimum   braking   pressure   more  
q

uickly   and   therefore   reduce   the   stopping  
di

stance.
It
  is   triggered   according   to   the   speed   at   which  
t

he   brake   pedal   is   pressed.   This   is   felt   by   a  
r

eduction in the resistance of the pedal and an
increase
  in   the   effectiveness   of   the   braking.
Anti-slip regulation (ASR)
The ASR system (also known as Traction Control)   optimises   traction   in   order   to   limit  
w

heel   slip   by   acting   on   the   brakes   of   the   driving  
w

heels   and   on   the   engine.   It   also   improves  
t

he directional stability of the vehicle on
acceleration.
Dynamic stability control (DSC)
If there is a difference between the path
followed   by   the   vehicle   and   that   required   by  
t

he   driver,   the   DSC   monitors   each   wheel   and  
a

utomatically   acts   on   the   brake   of   one   or   more  
w

heels   and   on   the   engine   to   return   the   vehicle  
t

o   the   required   path,   within   the   limits   of   the   laws  
o

f   physics.

Grip control
Special patented traction control system which improves   traction   on   snow,   mud   and   sand.
This
  system,   the   operation   of   which   has   been  
o

ptimised   for   each   situation,   allows   you   to  
m

anoeuvre   in   most   conditions   of   poor   grip  
(

  205/50   R   17   tyres,   this   system   offers  
a

  compromise   between   safety,   adhesion   and  
t

raction.   These   tyres   work   equally   well   in   winter  
a

nd   summer.
A five-position selector allows you to choose
the
  setting   best   suited   to   the   driving   conditions  
en

countered.
An
  indicator   lamp   associated   with   each   mode  
c

omes   on   to   confirm   your   choice.
A specific and additional display appears
temporarily
  in   the   touch   screen   to   confirm   the  
s

election   made   with   the   knob. Every
  time   the   ignition   is   switched   off,  
t

Differents
  modes   are   provided:
Standard (ESC)
This mode is calibrated for a low level of wheel s
