Collision risk alert
System providing a warning to the driver that their vehicle is at risk of collision with the vehicle in front.
T he   collision   risk   alert   system   can   be   activated  
o

r   deactivated   by   the   driver.
From
  the   secondary   page   of   the   "Driving
assistance "
  menu:
F

s
elect the "Vehicle settings "
  menu,
F
 
c
heck   the   "Collision risk alert "
  line   and  
c

onfirm.
This
  system   has   been   designed   to  
i

mprove   driving   safety.
It
  is   the   responsibility   of   the   driver   to  
k

eep   a   constant   check   on   the   state   of  
t

he   traffic,   to   assess   the   relative   speed  
a

nd   distance   of   other   vehicles.
The
  collision   risk   alert   system   can   never  
r

eplace   the   need   for   vigilance   on   the  
p

art   of   the   driver.
This
  system   operates   from   20   mph  
(

30 km/h),   only   when   other   vehicles   are  
r

unning   in   the   same   direction   as   your  
v

ehicle;   the   system   does   not   detect  
s

tationary   objects.   A   radar   is   fitted   at  
t

he   front   of   the   vehicle. The
  alert   thresholds   determine   how   you   want   to  
b

e   alerted   to   the   presence   of   a   vehicle   running  
i

n   front   of   you.
You
  can   choose   from   three   thresholds:
-
 
1
:   
"
Distant",   to   be   given   an   early   alert  
(

cautious
 d
riving).
-
 
2
:   "Normal".
-
 
3
:   
"
Close",   to   be   given   a   later   alert   (sporty  
d

riving).
Setting the thresholds for
the alert
This function can be deactivated permanently   by   a   CITROËN   dealer   or   a  
q

ualified
 w
orkshop.
From

The change from one level of alert to   the   next   takes   place   if   the   driving  
c

onditions   do   not   change   (speed  
u

nchanged,   no   change   of   lane...)
Severe
  weather   conditions   (very   heavy  
r

ain,   accumulation   of   snow   in   front  
o

f   the   radar)   may   inter fere   with   the  
o

peration   of   the   system,   resulting   in  
t

he   display   of   the   message   "System
inactive: Reduced visibility ".
  The  
s

ystem   remains   unavailable   until   the  
m

essage
 d
isappears.
If
  the   speed   of   your   vehicle   is   too   high  
w

hen   approaching   another   vehicle,   the  
f

irst   level   of   alert   may   not   be   displayed:  
t

he   level   2   alert   may   be   displayed  
d

i r e c t l y.
On
  the   other   hand,   the   level   1   alert  
i

s   never   displayed   with   the   triggering  
t

hreshold   3   (close).
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

ynamics,   the   speed   of   your   vehicle   and  
t

he   speed   of   the   vehicle   in   front,   the   driving  
c

onditions,   the   situation   with   your   vehicle  
(

cornering,   pedals   pressed,   etc.)   to   trigger   the  
a

lert   at   the   right   moment. Level 3
:   an   increase   in  t
he   tension   of   the   driver's  
s

eat   belt,   to   hold   the   driver  
a

gainst   the   backrest   of   their  
sea

t.
The
  3
rd level of alert is not triggered or i
s
 
interrupted   in   the   event   of   an   impact  
b

etween   the   two   vehicles.
The increase in the tension of the
driver's
  seat   belt   is   intended   only   as   an  
a

lert:
 
it
  does   not   in   any   circumstances  
a

ssure
  the   function   of   driver   safety.
The
 
triggering   of   this   alert   does   not   act  
o

n

safety   functions   provided   by   the  
s

eat
 
belts.

Operating fault
In the event of a fault, you are
alerted  by   the   display   of   the   Service

arning   lamp,   accompanied   by   a  
m

essage.
Consult
  a   CITROËN   dealer   or   a

a

ccumulations   of   grime   (dust,   mud...)  
o

Lane departure warning system
System which, using a camera which recognises   solid   or   broken   lines,   detects   the  
i

nvoluntary   crossing   of   longitudinal   traffic   lane  
m

arkings   on   the   ground.
To
  provide   safe   driving,   the   camera   analyses  
t

he   image   then,   if   the   driver's   attention   drops,  
t

riggers   a   warning   if   the   vehicle   drifts   over  
a

  lane   marking   (speed   higher   than   50   mph  
(

80 km/h)).
This
  system   is   particularly   useful   on   motor ways  
a

nd   main   roads. Activation
  and   deactivation   of   the   function   is  
d

one   in   the   touch   screen   tablet.

Parking sensors
This function cannot, in any
circumstances,   take   the   place   of   the

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

 t

hirty   centimetres,   the   audible   signal   becomes
 c

ontinuous.

This supplements the audible signal by d isplaying   bars   in   the   screen   or   the   instrument
