In the event of a fault with the system, this   warning   lamp   is   displayed a

ccompanied   by   a   message.
Operating fault
Have the system checked by a CITROËN dealer   or   a   qualified   workshop.
At
  the   first   use   of   the   system   after  
r

epair,   a   message   may   be   displayed  
i

ndicating   that   the   system   is   initialising.  
T

is
 
designed
 
to
 
improve

esponsibility
 
to
 
constantly

to   asses   the   distances   and   relative   speeds   of  
o

ther
 
vehicles
 
and
 
to
 
predict
 
their
 
movements   before   deciding   whether   to   change   lane.
The

s

ensors   located   in   the   bumper.
Certain
  types   of   obstacle   (stake,   roadworks  
c

one,   etc.)   detected   initially   will   no   longer   be  
d

etected   at   the   end   of   the   manoeuvre,   if   they

f   detection.
Parking sensors
This function cannot, in any
circumstances,   take   the   place   of   the  
v

igilance   of   the   driver. The
  system   is   switched   on   by   engaging   reverse  
g

e a r.
This   is   confirmed   by   an   audible   signal.
The   system   is   switched   off   when   you   come   out  
o

f   reverse   gear.
Audible assistance
The proximity information is given by an i
ntermittent   audible   signal,   the   frequency   of   which i

ncreases   as   the   vehicle   approaches   the   obstacle.
The
  sound   emitted   by   the   speaker   (right   or   left)
 i

ndicates   the   side   on   which   the   obstacle   is   located.
When
  the   distance   between   the   vehicle   and
 t

he   obstacle   becomes   less   than   approximately
 t

hirty   centimetres,   the   audible   signal   becomes
 c

ontinuous.
Rear parking sensors
Visual assistance
This supplements the audible signal by d isplaying   bars   in   the   screen   or   the   instrument  
p

anel   which   move   progressively   nearer   to  
t

he   vehicle.   When   the   obstacle   is   near,   the  
"

Danger"   symbol   is   displayed.

Front parking sensors
The sound emitted by the speaker (front or   rear)   indicates   whether   the   obstacle  
i

s   in   front   or   behind. The
  system   will   be   deactivated  
a

utomatically   if   a   trailer   is   being  
t

a

  towbar   (vehicle   fitted   with   a   towbar  
i

nstalled   in   line   with   the   manufacturer's  
r

ecommendations).In
  bad   weather   or   in   winter,   ensure  
t

hat   the   sensors   are   not   covered   with  m
ud,   ice   or   snow.   When   reverse   gear   is  e
ngaged,   an   audible   signal   (long   beep)  
i

ndicates   that   the   sensors   may   be   dirty.
Certain
  sound   sources   (motorcycle,  
l

orry,   pneumatic   drill,   etc.)   may   trigger  
t

he   audible   signals   of   the   parking  
s

ensor   system.
In
 
addition   to   the   rear   parking   sensors,   the  
f

ront
 
parking   sensors   are   triggered   when   an  
o

bstacle   is   detected   in   front   and   the   speed   of  
t

he
 
vehicle   is   still   below   6   mph   (10   km/h).

Park Assist
This system provides active assistance with parking,   detecting   a   parking   space   then  
c

ontrolling   the   steering   to   park   in   the   space.
It
  controls   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   wheel  
t

urns   quickly:   do   not   hold   the   steering  
w

heel,   do   not   place   your   hand   between  
t

he   spokes   of   the   steering   wheel   and  
t

ake   care   with   loose   and   bulky   clothing,  
s

carves,   handbags...   There   is   a   risk   of  
in

jury.
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:
