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 Â
o
r  deactivated  by  the  driver.
From
 the  secondary  page  of  the  "Driving
assistance "
 menu:
F
s
elect the "Vehicle settings "
 menu,
F
Â
c
heck  the  "Collision risk alert "
 line  and Â
c
onfirm.
This
 system  has  been  designed  to Â
i
mprove  driving  safety.
It
 is  the  responsibility  of  the  driver  to Â
k
eep  a  constant  check  on  the  state  of Â
t
he  traffic,  to  assess  the  relative  speed Â
a
nd  distance  of  other  vehicles.
The
 collision  risk  alert  system  can  never Â
r
eplace  the  need  for  vigilance  on  the Â
p
art  of  the  driver.
This
 system  operates  from  20  mph Â
(
30 km/h),  only  when  other  vehicles  are Â
r
unning  in  the  same  direction  as  your Â
v
ehicle;  the  system  does  not  detect Â
s
tationary  objects.  A  radar  is  fitted  at Â
t
he  front  of  the  vehicle. The
 alert  thresholds  determine  how  you  want  to Â
b
e  alerted  to  the  presence  of  a  vehicle  running Â
i
n  front  of  you.
You
 can  choose  from  three  thresholds:
-
Â
1
: Â Â
"
Distant",  to  be  given  an  early  alert Â
(
cautious
 d
riving).
-
Â
2
: Â "Normal".
-
Â
3
: Â Â
"
Close",  to  be  given  a  later  alert  (sporty Â
d
riving).
Setting the thresholds for
the alert
This function can be deactivated permanently  by  a  CITROËN  dealer  or  a Â
q
ualified
 w
orkshop.
From

The change from one level of alert to  the  next  takes  place  if  the  driving Â
c
onditions  do  not  change  (speed Â
u
nchanged,  no  change  of  lane...)
Severe
 weather  conditions  (very  heavy Â
r
ain,  accumulation  of  snow  in  front Â
o
f  the  radar)  may  inter fere  with  the Â
o
peration  of  the  system,  resulting  in Â
t
he  display  of  the  message  "System
inactive: Reduced visibility ".
 The Â
s
ystem  remains  unavailable  until  the Â
m
essage
 d
isappears.
If
 the  speed  of  your  vehicle  is  too  high Â
w
hen  approaching  another  vehicle,  the Â
f
irst  level  of  alert  may  not  be  displayed: Â
t
he  level  2  alert  may  be  displayed Â
d
i r e c t l y.
On
 the  other  hand,  the  level  1  alert Â
i
s  never  displayed  with  the  triggering Â
t
hreshold  3  (close).
Alerts
According to the collision risk detected by the system  and  the  alert  threshold  chosen,  three Â
l
evels  of  alert  can  be  triggered.
Level 1 :
 visual  alert  only  (orange) Â
i
ndicating  that  the  vehicle  in  front  is Â
v
ery  close.  The  message  "Vehicle
close "
 is  displayed.
Level 2 :
 visual  (red)  and  audible Â
a
lerts  indicating  that  a  collision  is Â
i
mminent.  The  message  "Brake! " is
displayed.
This
 level  of  alert  is  based  on  the  inter-vehicle Â
t
ime  between  your  vehicle  and  the  one  in  front.
This
 level  of  alert  is  based  on  a  time  before Â
c
ollision.  It  takes  account  of  the  vehicle Â
d
ynamics,  the  speed  of  your  vehicle  and Â
t
he  speed  of  the  vehicle  in  front,  the  driving Â
c
onditions,  the  situation  with  your  vehicle Â
(
cornering,  pedals  pressed,  etc.)  to  trigger  the Â
a
lert  at  the  right  moment. Level 3
:  an  increase  in  t
he  tension  of  the  driver's Â
s
eat  belt,  to  hold  the  driver Â
a
gainst  the  backrest  of  their Â
sea
t.
The
 3
rd level of alert is not triggered or i
s
Â
interrupted  in  the  event  of  an  impact Â
b
etween  the  two  vehicles.
The increase in the tension of the
driver's
 seat  belt  is  intended  only  as  an Â
a
lert:
Â
it
 does  not  in  any  circumstances Â
a
ssure
 the  function  of  driver  safety.
The
Â
triggering  of  this  alert  does  not  act Â
o
n
Â
the
Â
safety  functions  provided  by  the Â
s
eat
Â
belts.

Lane departure warning system
System which, using a camera which recognises  solid  or  broken  lines,  detects  the Â
i
nvoluntary  crossing  of  longitudinal  traffic  lane Â
m
arkings  on  the  ground.
To
 provide  safe  driving,  the  camera  analyses Â
t
he  image  then,  if  the  driver's  attention  drops, Â
t
riggers  a  warning  if  the  vehicle  drifts  over Â
a
 lane  marking  (speed  higher  than  50  mph Â
(
80Â km/h)).
This
 system  is  particularly  useful  on  motor ways Â
a
nd  main  roads. Activation
 and  deactivation  of  the  function  is Â
d
one  in  the  touch  screen  tablet.

Parking sensors
This function cannot, in any
circumstances,  take  the  place  of  the Â
v
igilance  of  the  driver. The
 system  is  switched  on  by  engaging  reverse Â
g

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

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

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

hat  the  sensors  are  not  covered  with  m
ud,  ice  or  snow.  When  reverse  gear  is  e
ngaged,  an  audible  signal  (long  beep) Â
i
ndicates  that  the  sensors  may  be  dirty.
Certain
 sound  sources  (motorcycle, Â
