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  
y

our   vehicle   is   too   close   to   or   closing  
t

oo   quickly   on   the   vehicle   ahead   of   you,  
t

he   system   automatically   operates   the  
b

rakes   to   reduce   the   speed   of   impact.   A  
c

ollision   can   be   avoided   automatically   if   the

  are   then   alerted   by   the   display   of  
t

his   warning   lamp,   accompanied   by  
a

  automatic   braking   may   bring   the   vehicle   to  a
  complete   stop   if   the   situation   requires   it.
The
  brake   lamps   on   your   vehicle   come   on   to  
w

arn   other   road   users. The
  triggering   of   the   system   may   cause  
t

d

epresses   the   clutch   pedal   quickly

Setting the alert thresholds
Press this button repeatedly to cycle through   the   thresholds.
The
  default   setting   is   "Normal".
The
 
alert
 
thresholds   determine   how   you   want   to   be   warned   of   the   imminent   risk   of   collision   with   the  
v

ehicle
 
ahead   of   you.
You
 
can
 
choose   one   of   three   thresholds:
A.
 "

Far",
  to   be   given   early   warning   (cautious   driving).
B.
 "

Normal".
C.
 "

Close",   for   a   later   warning   (sporty   driving).
Deactivation / Reactivation
Press this button for more than 3 seconds.

Never leave accumulations of snow or any   object   projecting   above   the   bonnet  
o

r   in   front   of   the   roof:   this   might   fall   into  
t

he   field   of   vision   of   the   sensor   and  
g

enerate   a   detection.
Operating limits
The system  o nly  d etects  v ehicles  (cars,  lorries) t
hat   are   stationary   or   moving   in   the   same  
d

irection   as   your   vehicle. In
  difficult   weather   conditions   (very  
h

eavy   rain,   snow,   fog,   hail...),   braking  
d

istances   increase,   which   can   reduce  
t

he   ability   of   the   system   to   avoid   a  
c

ollision.
The
  driver   must   therefore   remain  
par

ticularly
 v
igilant.
The
  system   is   not   triggered   or   is   interrupted   if  
t

he
 d
river:
-
 
a
ccelerates   strongly   (even   if   the   speed  
l

imiter   is   on),
-
 
o
r   turns   the   steering   wheel   suddenly  
(

avoiding
 m
anoeuvre).
Detection
  capability   is   less   effective   if:
-
 
y
ou   are   driving   on   roads   with   pronounced  
b

ends   and/or   on   roads   in   poor   condition,
-
 
y
our   vehicle   is   excessively   loaded,   as  
t

his   changes   the   horizontal   attitude   of   the  
v

ehicle.
-
 
y
our   vehicle   skids.
It
  does   not   detect   small   vehicles  
(

bicycles,   motorcycles),   pedestrians   or  
a

nimals,   nor   non-reflective   stationary  
ob

jects.Unwanted triggering of the system
It is possible for the system to detect a risk of imminent   collision   and   start   working,   in   the  
fo

llowing
 c
onditions
 in par
ticular:
-
 
d
etection   of   an   object   located   close   to   the  
e

b

arrier,   lamp   post   or   road   sign),
-
 
d
etection   of   a   structure   located   at   the   top  
o

h

oarding,   steet   lighting),
-
 
d
etection   of   reflective   objects   (central  
r

eservation...)   in   the   road,

Electrical energy economy mode*
System which manages the duration of use of certain functions to conserve a sufficient level of charge   in   the   battery.
After
  the   engine   has   stopped,   you   can   still   use   functions   such   as   the   audio   system, windscreen  
w

ipers,   dipped   beam   headlamps, courtesy   lamps,   etc.   for   a   maximum   combined   duration   of  
t

wenty minutes.
This
  period   may   be   greatly   reduced   if   the   battery   is   not   fully   charged.
Let
  the   engine   run   for   the   duration  
s

pecified   to   ensure   that   the   battery  
c

harge   is   sufficient.
Do
  not   repeatedly   and   continuously  
r

estart   the   engine   in   order   to   charge   the  
b

attery.
A
  flat   battery   prevents   the   engine   from  
s

tarting.
Refer
  to   the   "Battery"   section.
Switching to economy mode
Once this time has elapsed the active functions are   put   on   standby.
Exiting economy mode
These functions are reactivated automatically next   time   the   vehicle   is   driven.
To restore the use of these functions
immediately,
  start   the   engine   and   let   it   run   for   at
