2016 Citroen DS3 RHD sensor

Parking sensors
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.
This system cannot in any circumstances replace the   need   for   vigilance   on   the   part   of   the   driver.
Audible assistance
The proximity information is given by an intermittent   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   which   move  
p

rogressively   nearer   to   the   vehicle.
When
  the   obstacle   is   very   close,   the   "Danger"  
s

ymbol   is   displayed   in   the   screen.
The
 
system
 
is
 
switched
 
on
 
by
 
engaging
 
reverse
 
g

e a r.
This
 
is
 
confirmed
 
by

Contact
 
a
 
CITROËN   dealer   or   a   qualified
 w

orkshop.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).
The
  front   parking   sensors   are   interrupted   if  
t

he   vehicle   stops   for   more   than   three   seconds  
i

n   for ward   gear,   if   no   further   obstacles   are  
d

etected   or   when   the   speed   of   the   vehicle  
e

xceeds   6   mph   (10   km/h).
The
  sound   emitted   by   the   speaker  
(

front   or   rear)   indicates   whether   the  
o

bstacle   is   in   front   or   behind. 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.
The
  function   will   be   deactivated  
a

utomatically   if   a   trailer   is   being   towed

LED daytime running lampsThis daytime lighting, a signature of the vehicle, comprises   two   sets   of   light-emitting   diodes  
(

LEDs),   located   in   vertical   housings   below   each  
h

eadlamp.
On
  starting   the   vehicle,   in   daylight   the   daytime  
r

unning   lamps   come   on   automatically,   if   the

If
  the   sidelamps   and   headlamps   are   switched

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

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

or   more   than   one   minute,   by   pushing

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,

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   need   for   vigilance  
o

n   the   part   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.
For
  more   information   on   the  
i

dentification   markings,   refer   to   the  
c

orresponding
 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 Brake is a driving assistance system   that   aims   to   avoid   a   frontal   collision  
o

r   reduce   the   speed   of   an   impact   if   the   driver  
d

oes   not   react   sufficiently   (inadequate   brake  
a

pplication). This
  system   is   designed   to   improve  
d

riving   safety.
It
  remains   the   driver's   responsibility   to  
c

ontinuously   monitor   the   state   of   the  
t

raffic   and   to   assess   the   distances   and  
r

elative   speeds   of   other   vehicles.
Active
  City   Brake   can   in   no  
c

ircumstances   replace   the   need   for  
v

igilance   on   the   part   of   the   driver.
Never
  look   at   the   laser   sensor   through  
an o

ptical
 in
strument
 (

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.
