The active cruise control uses only engine braking   to   slow   the   vehicle.   Consequently   the  
v

ehicle   looses   speed   slowly,   as   when   releasing  
t

he   accelerator   pedal.
The
  system   is   paused   automatically:
-
 
i
f   the   vehicle   in   front   slows   down   to   much  
o

r   too   suddenly,   and   the   driver   does   not  
b

rake,
-
 
i
f   a   vehicle   comes   between   your   vehicle  
a

nd   the   vehicle   in   front,
-
 
i
f   the   system   does   not   slow   the   vehicle  
e

nough   to   continue   to   maintain   a   safe  
d

istance,   for   example   when   descending   a  
s

teep   hill.
Limits of operation
As the radar's field of view is quite narrow, it is possible   that   the   system   may   not   detect:
The
  cruise   control   does   not   take   account   of:
-
 
s
tationary   vehicles,
-
 
v
ehicles   driving   in   the   opposite   direction.
-
 
v
ehicles   of   reduced   width,   such   as  
m

otorcycles,   for   example,
-
 
v
ehicles   not   running   in   the   middle   of   the  
lan

e, -
 
v
ehicles   entering   a   corner,
-
 
v
ehicles   changing   lane   at   the   last   moment.

In the event of a fault with the active cruise
control,  you   are   alerted   by   an   audible   signal  
a

nd   display   of   the   message   message   "Driving

Have
  the   system   checked   by   a   CITROËN

ealer   or   a   qualified   workshop. When
  the   cruise   control   is   working,   take  
c

are   if   making   a   maintained   press   on  
o

ne   of   the   cruise   control   programmed  
s

peed   modification   buttons:   this   can

do n

ot use the active cruise control on
slippery
  sur faces   or   in   heavy   traffic.
When
  descending   a   steep   hill,   the

ruise   control   may   not   be   able   to  
p

revent   the   vehicle   from   exceeding   the

C

ITROËN   may   inter fere   with   the

To
  avoid   any   risk   of   jamming   the   pedals:

-
 
n
ever   fit   one   mat   on   top   of   another.

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

If
  the   speed   of   your   vehicle   is   too   high  
w

f

irst   level   of   alert   may   not   be   displayed:

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.

This system indicates the proximity of an obstacle   (person,   vehicle,   tree,   gate,   etc.)  
w

hich   comes   within   the   field   of   detection   of  
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  
a

re   located   in   blind   spots   in   the   sensors'   field  
o

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.

360 Vision
This system provides a view in the instrument panel   of   the   near   surroundings   of   your   vehicle,  
u

sing   cameras   mounted   at   the   front   and   rear   of  
y

our   vehicle   and   under   the   door   mirrors.
Depending
  on   the   angle   of   view   chosen  
(front
  view,   rear   view   or   360°   panoramic   view),  
3

60 Vision   provides   special   visual   assistance  
i

n   particular   driving   conditions   such   as   when  
e

ntering   a   blind   crossing   or   manoeuvring   in  
a

reas   of   reduced   visibility.
Once
  activated,   this   function   operates   up   to  
9 m

ph   (15   km/h).   Above   18   mph   (30   km/h),   the  
f

unction   is   deactivated   automatically. This
  system   is   a   visual   aid   which   in   no  
c

ircumstances   can   replace   the   need   for  
v

igilance   on   the   part   of   the   driver.
The   images   provided   by   the   cameras  
m

ay   be   deformed   by   the   relief.   The  
p

resence   of   areas   in   shade,   in   sunny  
c

onditions,   or   of   low   ambient   light   may  
d

arken   the   image   and   reduce   contrast.
Forward vision
The camera located in the front bumper is a
ctivated   and   views   of   the   areas   located   at  
f

ront   left   and   front   right   appear   simultaneously

Rear vision
The camera located in the tailgate is activated and   the   view   of   the   area   behind   your   vehicle   is  
d

isplayed   in   the   instrument   panel   and   behaves

The
  blue   lines   represent   the   width   of   your  
v

ehicle   (excluding   mirrors):   they   move  
a

ccording   to   the   position   of   the   steering   wheel.
The
