The vehicle can be stopped whatever the position   of   the   gear   selector   (N , E or R ).
However,
  there   is   an   audible   signal   on   opening  
t

he   driver's   door   if   the   gear   selector   is   not   at  
p

osition N .
Switching off
When the vehicle is stopped with the e
ngine   running,   always   put   the   gear  
s

elector to neutral N .
There
  is   a   continuous   audible   signal

On a descending slope, with the vehicle
stationary and reverse gear engaged,
the vehicle is held momentarily when you
release the brake pedal.

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

nd   contribute   towards   better   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
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.
Traction control (TRC)
This system optimises traction in order to limit wheel   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   the  
d

river,   this   system   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

Active City Brake
Active City B rake  i s  a  d riving  a ssistance  s ystem  t
hat   aims   to   avoid   a   frontal   collision   or   reduce  
t

he   speed   of   an   impact   if   the   driver   does   not  
r

eact   or   reacts   too   late   (brake   application   too  
l

ate). This
  system   is   designed   to   improve  
d

riving   safety.
It
  remains   the   driver's   responsibility   to  
c

ontinuously   monitor   the   state   of   the  
t

raffic   and   to   assess   the   distances   and  
r

elative   speeds   of   other   vehicles.
Active
  City   Brake   can   in   no  
c

ircumstances   replace   the   need   for  
v

igilance   on   the   part   of   the   driver.
Never
  look   at   the   laser   sensor   through  
a

n   optical   instrument   (magnifying   glass,  
m

icroscope...)   at   a   distance   of   less   than  
1

0   centimetres:   risk   of   eye   injury.Automatic
  braking   occurs   later   than   if  
d

one   by   the   driver,   so   as   to   intervene  
o

nly   when   there   is   a   high   risk   of  
c

ollision.Principle
Using a laser sensor and a camera located at the   top   of   the   windscreen,   this   system   detects  
a

  vehicle   running   in   the   same   direction   or  
s

tationary   ahead   of   your   vehicle.
When
  necessary,   the   vehicle's   braking   system  
i

s   operated   automatically   to   reduce   the   speed  
o

f   impact   or   to   help   avoid   a   collision   with   the  
v

ehicle

Operation
Three levels of operation are possible:
●  P re-collision alert :
  if   a   risk   of   collision w

ith   a   vehicle   is   detected,   a   warning   lamp
 c

omes   on   in   the   instrument   panel   together
 w

ith   an   audible   signal   to   encourage   the
 d

river   to   make   an   avoiding   manoeuvre.   The
 t

hresholds   for   triggering   the   alert   can   be   set.
●
 
Br
aking assistance :
  increases   the  
b

raking   started   by   the   driver,   only   if   a   risk  
o

f   collision   is   detected.
●
 
A
utomatic pre-collision braking:
  when

our   vehicle   is   too   close   to   or   closing  
t

oo   quickly   on   the   vehicle   ahead   of   you,  
t

Snow chains
In wintry conditions, snow chains improve traction as well as the behaviour of the vehicle when braking.
Advice on installation
