When the active cruise control is automatically paused, it can only be reactivated when safe conditions are restored. The message "Activation not   possible,   conditions   unsuitable"   is   displayed   while   reactivation   is   not   possible.
When
  the   conditions   allow,   it   is   recommended   that   the   function   be   reactivated   by   pressing   button   2 or 3,
  which   will   make   the   current   speed   of  
y

our   vehicle   the   new   cruise   speed   setting,   rather   than   by   pressing   button   4   (on/pause)   which   reactivates   the   cruise   control   using   the   old   cruise  
s

peed   setting,   which   may   be   very   different   from   the   current   speed   of   your   vehicle.

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   in  
c

orners,   in   particular   on   poor   or   slippery   road  
su

rfaces.
The
  ABS   prevents   wheel   lock   in   the   event   of  
em

ergency
 b
raking.
The
  electronic   brake   force   distribution   system  
m

anages   the   braking   pressure   wheel   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  
i

ncrease   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  
a

cceleration.
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.

Intelligent traction control
system ("Snow motion")
When this warning lamp comes on, coupled   with   the   STOP w arning lam p, a

ccompanied   by   an   audible   signal   and   a
 m

essage,   it   indicates   that   there   is   a   fault
 w

ith   the   electronic   brake   force   distribution
 (

EBFD),   which   could   cause   loss   of   control
 o

f   the   vehicle   when   braking.
Operation
When this warning lamp comes on, accompanied   by   an   audible   signal  
a

nd   a   message,   it   indicates   that   there  
i

s   a   fault   with   the   ABS,   which   could  
c

ause loss of control of the vehicle
when
 b

raking. Depending
  on   version,   your   vehicle   has   a  
s

ystem   to   help   driving   on   snow:   intelligent
traction control .
This   system   detects   situations   of   difficult  s
ur face   adhesion   that   could   make   it   difficult   to  
m

ove   off   or   make   progress   on   deep   fresh   snow  
o

r   compacted   snow.
In these situations, the intelligent traction
control
 

limits   the   amount   of   wheel   slip   to  
p

rovide   the   best   traction   and   trajectory   control  
f

or   your   vehicle.
The
  use   of   snow   tyres   is   strongly  
r

ecommended   on   sur faces   offering   low   levels  
o

f   adhesion.
Anti-lock braking system (ABS)
and electronic brake force
distribution (EBFD)When changing w heels  ( tyres  a nd  r ims),  m
ake   sure   that   these   are   approved   for  
y

our   vehicle.
Normal
  operation   of   the   ABS   may   make  
i

tself   felt   by   slight   vibrations   of   the   brake  
ped

al.
In emergency braking, press
very firmly without releasing the
pressure.
You must stop as soon as it is safe to do so.

cases,

dealer
