Switching on
The cruise control is switched on manually, i
t   requires   a   vehicle   speed   of   between   18   and  
1

12 mph   (30   and   180   km/h).
An
  automatic   gearbox   must   be   in   position   D
or M . Other wise,
  the   last   setting   made   will   be   used  
w

hen   switching   on   the   system.
Switching   off   the   ignition   cancels   any  
p

rogrammed   speed   setting.
When   the   cruise   control   is   operating,  S
top   &   Start   is   automatically  d
eactivated.

ringing   it   to   a   complete   stop,   the  
s

ystem   holds   the   vehicle   stationary   ;

Alerts
According to the collision risk detected by the system   and   the   alert   threshold   chosen,   three  
l

evels   of   alert   can   be   triggered.
Level 1 :
  visual   alert   only   (orange)  
i

ndicating   that   the   vehicle   in   front   is  
v

ery   close.   The   message   "Vehicle
close "
  is   displayed.
Level 2 :
  visual   (red)   and   audible  
a

lerts   indicating   that   a   collision   is  
i

mminent.   The   message   "Brake! " is
displayed.
This
  level   of   alert   is   based   on   the   inter-vehicle  
t

ime   between   your   vehicle   and   the   one   in   front.
This
  level   of   alert   is   based   on   a   time   before  
c

ollision.   It   takes   account   of   the   vehicle  
d

Park Assist
This system provides active assistance with parking.   It   detects   a   parking   space   then  
o

perates   the   steering   to   park   in   the   space.
It
  operates   the   steering   while   the   driver  
m

anages   the   accelerator,   brakes,   gears   and  
c

lutch   (manual   gearbox).   During   phases   of  
e

ntry   into   and   exit   from   a   parking   space,   the  
s

ystem   provides   visual   and   audible   information  
t

o   the   driver   in   order   to   make   the   manoeuvres  
s

afe.   It   may   be   necessary   to   move   for wards  
a

nd   backwards   more   than   once. During
  a   manoeuvre   the   steering  
w

heel   turns   quickly:   do   not   hold   the  
s

teering   wheel,   do   not   place   your   hands  
b

etween   the   spokes   of   the   steering  
w

heel   and   take   care   with   loose   and  
b

ulky   clothing,   scarves,   handbags...  
T

here   is   a   risk   of   injury.
When
  Park   Assist   is   activated,   it  
p

revents   a   change   to   STOP   mode   of  
S

top   &   Start.   In   STOP   mode,   activation  
o

f   Park   Assist   restarts   the   engine.
The
  Park   Assist   system   cannot   in   any  
c

ircumstances   replace   the   need   for  
v

igilance   on   the   part   of   the   driver.
The
  driver   must   remain   in   control  
o

f   their   vehicle   ensuring   that   the  
s

pace   remains   clear   throughout   the  
m

anoeuvre.
In
  some   circumstances,   the   sensors  
m

ay   not   detect   small   obstacles   located  
i

n   their   blind   spots.
The
  driver   can   take   control   at   any   time   by  
g

ripping   the   steering   wheel. The
  Park   Assist   system   provides   assistance   for  t
he   following   manoeuvres:

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  
su

rfaces.
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  
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

When this warning lamp comes on, coupled   with   the   STOP  and   ABS   warning

EBFD).
Anti-lock braking system (ABS) and electronic brake force
distribution (EBFD)
The fixed illumination of this warning lamp   indicates   that   there   is   a   fault  
w

ith   the   ABS. 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   grip   that   could   make   it   difficult   to   move  
o

ff   or   make   progress   on   deep   fresh   snow   or  
c

ompacted   snow.
In these situations, the intelligent traction
control
 

limits   the   amount   of   wheel   spin   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.
When
  changing   wheels   (tyres   and  
r

ims),   ensure   that   these   are   approved  
f

or   your   vehicle.
Normal
  operation   of   the   ABS   may   make  
i

tself   felt   by   slight   vibrations   of   the   brake  
ped

al.
In emergency braking, press ver y
firmly and maintain this pressure.
You must stop as soon as it is safe to do so.
In
 
both
 
cases,   have   the   system   checked   by   a  
C

ITROËN   dealer   or   a   qualified   workshop   as
