sensor CITROEN DS3 CABRIO 2015 Handbook (in English)

Rear parking sensors
System consisting of four proximity sensors, located   in   the   rear   bumper.
This
  detects   any   obstacle   (person,   vehicle,  
t

ree,   gate,   etc.)   behind   the   vehicle,   except  
o

bstacles   located   just   below   the   bumper.
An object, such as a stake, a roadworks cone   or   any   other   similar   object   may b

e   detected   at   the   beginning   of   the
 m

anoeuvre,   but   may   no   longer   be   detected
 w

hen   the   vehicle   comes   close   to   it.
The parking sensor system cannot in any   circumstances   take   the   place   of  
v

igilance   on   the   part   of   the   driver.
The
 
system   is   activated   as   soon   as   reverse  
g

ear
 
is   engaged,   accompanied   by   an   audible  
s

ignal.   The   proximity   information   is   given   by:
-
 
a

n   audible   signal,   which   becomes   more  
r

apid   as   the   vehicle   approaches   the  
o

bstacle.
-
 
a

 
graphic   (according   to   version)   in   the  
m

ultifunction   screen,   with   blocks   which  
b

ecome   increasingly   closer   to   the   vehicle.
Activation
When the distance between the rear of the vehicle a
nd   the   obstacle   is   less   than   thirty   centimetres,   the a

udible   signal   becomes   continuous   and   the   "Danger"
 s

ymbol   appears   in   the   multifunction   screen.
On
  completion   of   the   manoeuvre,   when   you   exit
 r

everse   gear,   the   system   becomes   inactive.

do n

ot cover the sunshine sensor,
coupled
  with   the   rain   sensor   and  
l

Automatic rain sensitive
windscreen wipers
The windscreen wipers operate automatically, without   any   action   on   the   part   of   the   driver,   if  
r

ain   is   detected   (sensor   behind   the   rear   view  
m

irror),   adapting   their   speed   to   the   intensity   of  
t

he   rainfall.
Activation
This is controlled manually by the driver by pushing s talk A to the "AUTO" p osition.
It is accompanied by the illumination of this indicator   lamp   in   the   instrument   panel   and a

  message   in   the   multifunction   screen.
Switching off
This is controlled manually by the driver by   moving   stalk   A   upwards,   returning   it   to  
p

osition

"0".
It
  is   accompanied   by   the   indicator   lamp
 i

n   the   instrument   panel   going   off   and   a
 m

essage   in   the   multifunction   screen.The
  automatic   wiping   must   be  r
eactivated   if   the   ignition   has   been   off  
f

or   more   than   one   minute,   by   pushing  
s

talk   A   downwards.
Visibility

Operating fault
If an automatic wiping fault occurs, the wipers will   operate   in   intermittent   mode.
Have
  it   checked   by   a   CITROËN   dealer   or   a  
q

ualified
 w
orkshop. To retain the effectiveness of the flat
wiper
  blades,   it   is   advisable   to:
-
 
h
andle   them   with   care,
-
 
c
lean   them   regularly   using   soapy  
w

ater,
-
 
n
ot   use   them   to   hold   a   sheet   of  
c

ardboard   against   the   windscreen,
-
 
r
eplace   them   at   the   first   signs   of  
w

e a r.
Do
  not   cover   the   rain   sensor,   linked  
w

ith   the   sunshine   sensor   and   located   in  
t

he   centre   of   the   windscreen   behind   the  
r

ear   view   mirror.
Switch
  off   the   automatic   wiping   when  
u

sing   an   automatic   car   wash.
In
  winter,   it   is   advisable   to   wait   until   the  
w

indscreen   is   completely   clear   of   ice  
b

efore   activating   the   automatic   wiping.This
  position   allows   the   wiper   blades   to  
b

e   lifted   for   winter   parking,   cleaning   or  
r

eplacement   without   damaging   the   bonnet.
In
  the   minute   following   switching   off   of   the  
i

gnition,   any   action   on   the   wiper   stalk   positions  
t

he   wipers   vertically.
To
  park   the   wipers   after   this   has   been   done,
 s

witch   on   the   ignition   and   operate   the   wiper   stalk.

Under-inflation detection
System which automatically checks the pressures of the tyres while driving.
T he   under-inflation   detection   system  
d

oes   not   replace   the   vigilance   or   the  
r

esponsibility   of   the   driver.
This
  system   does   not   avoid   the   need   to  
c

heck   the   tyre   pressures   (including   the  
s

pare   wheel)   every   month   as   well   as  
b

efore   a   long   journey.
Driving
  with   under-inflated   tyres  
i

mpairs   road   holding,   extends   braking  
d

istances   and   causes   premature  
t

yre   wear,   particularly   under   arduous  
c

ondition   (high   loading,   high   speed,  
lon

g
 jo
urney).The
  inflation   pressures   defined   for  
y

our   vehicle   can   be   found   on   the   tyre  
p

ressure   label.
See
  the   "Identification   markings"  
s

ection.
Tyre
  pressures   should   be   checked  
w

hen   the   tyres   are   "cold"   (vehicle  
s

topped   for   1   hour   or   after   a   journey   of  
l

ess   than   6   miles   (10   km)   at   moderate  
s

peeds).
Other wise
  (when   hot),   add   0.3   bar   to  
t

he   pressures   shown   on   the   label.
Driving
  with   under-inflated   tyres  
i

ncreases   fuel   consumption.
The
  system   monitors   the   pressures   in   the   four  
t

yres,   once   the   vehicle   is   moving.
It
  compares   the   information   given   by   the   four  
w

heel   speed   sensors   with   reference values,
which must be reinitialised ever y time the
tyre pressures are adjusted or a wheel
changed .
The
  system   triggers   an   alert   as   soon   as   it  
d

etects   a   drop   in   the   inflation   pressure   of   one  
o

r   more   tyres.

Active City Brake
Active City Brakeis a driving assistance system that   aims   to   avoid   a   frontal   collision   or   reduce  
t

he   speed   of   an   impact   if   the   driver   does  
n

ot   take   sufficient   action   (inadequate   brake  
a

pplication).
This system is designed to improve driving safety.
I t   remains   the   driver's   responsibility   to c

ontinuously   monitor   the   state   of   the   traffic   and
 t

o   assess   the   distances   and   relative   speeds   of
 o

ther
 v
ehicle.
Active
  City   Brakecan   in   no   circumstances   replace
 t

he   need   for   vigilance   on   the   part   of   the   driver.
never   look   at   the   laser   sensor   through  an o
ptical in strument ( magnifying g lass, m

icroscope...)   at   a   distance   of   less   than  
1

0   centimetres:   risk   of   eye   injury.Automatic
  braking   occurs   later   than   if  
d

one   by   the   driver,   so   as   to   intervene  
o

nly   when   there   is   a   high   risk   of  
c

ollision.
Principle
Using a laser sensor located at the top of the windscreen,   this   system   detects   a   vehicle  
r

unning   in   the   same   direction   or   stationary  
a

head   of   your   vehicle.
When
  necessary,   the   vehicle's   braking   system  
i

s   operated   automatically   to   avoid   a   collision  
w

ith   the   vehicle   ahead.
Conditions for activation
Active City Brakeonly operates if the following conditions   are   met:
●
 
i
gnition   on,
●
 
t
he   vehicle   is   in   a   for ward   gear,
●
 
s
peed   is   between   about   3   and   18   mph  
(

5 and   30   km/h),
●
 
t
he   braking   assistance   systems   (ABS,  
E

BFD,   emergency   braking   assistance)   are  
n

ot faulty,
●
 
t
he   trajectory   control   systems   (ASR,   DSC)  
a

re   not   deactivated   or   faulty,
●
 
t
he   vehicle   is   not   in   a   tight   corner,
●
 
t
he   system   has   not   been   triggered   during  
t

he   previous   10   seconds.

163
Operating limits
The system only detects vehicles that are stationary   or   moving   in   the   same   direction   as  
y

our   vehicle.
It
  does   not   detect   small   vehicles  
(

bicycles,   motorcycles),   pedestrians   or  
a

nimals,   nor   non-reflective   stationary  
ob

jects. In
  difficult   weather   conditions   (very  
h

eavy   rain,   snow,   fog,   hail...),   braking  
d

istances   increase,   which   can   reduce  
t

he   ability   of   the   system   to   avoid   a  
c

ollision.
The
  driver   must   therefore   remain  
par

ticularly
 v
igilant.
Never
  leave   accumulations   of   snow   or  
a

ny   object   projecting   above   the   bonnet  
o

r   in   front   of   the   roof:   this   might   fall   into  
t

he   field   of   vision   of   the   sensor   and  
g

enerate   a   detection.
The
  system   is   not   triggered   or   is   interrupted   if  t
he d river:
-
 
a
ccelerates   strongly
-
 
o
r   turns   the   steering   wheel   suddenly  
(

avoiding
 m
anoeuvre).

165
Operating faults
In the event of an impact to the windscreen   at   the   sensor,   deactivate  
t

he   system   and   contact   a   CITROËN  
d

ealer   or   a   qualified   workshop to   have  
y

our   windscreen   replaced.
Never
  try   to   remove,   adjust   or   test  
t

he sensor.
Only
  a   CITROËN   dealer   or   a   qualified
 w

orkshop   is   able   to   work   on   the   system.
When
  towing   a   trailer   or   when   the  
v

ehicle   is   being   towed,   the   system   must  
b

e   deactivated.
Do not stick or other wise fix any object on the   windscreen   in   front   of   the   sensor.
Sensor fault
The operation of the laser sensor may suffer inter ference   from   accumulations   of   dirt   or  
m

isting   of   the   windscreen.   In   this   case   you   are  
w

arned   by   the   display   of   a   message.
Use
  the   windscreen   demisting   and   regularly  
c

lean   the   area   of   the   windscreen   in   front   of   the  
sen

sor.
System fault
In the event of a malfunction of the system, you are   warned   by   an   audible   signal   and   the   display  
o

f   the   message   "Automatic braking system
fault" .
Have
  the   system   checked   by   a   CITROËN  
d

ealer   or   a   qualified   workshop.
