automatic Citroen DS3 RHD 2016 1.G Service Manual

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  
l

ighting   stalk   is   in   position   "0" or "AUTO" .
If
  the   sidelamps   and   headlamps   are   switched  
o

n   manually   or   automatically,   the   daytime  
r

unning   lamps   go   off.

f

or   which   the   duration   is   fixed   at   60   seconds).

The vehicle's front and rear wipers are designed   to   improve   the   driver's   visibility  
p

rogressively   according   to   the   weather

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.

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.

Automatic operation of
hazard warning lamps
When braking in an emergency, depending on the   deceleration,   the   hazard   warning   lamps  
c

They
  switch   off   automatically   the   first   time   you  
a

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.

Braking assistance systems
Group of supplementary systems which help you   to   obtain   optimum   braking   in   complete  
s

afety   in   emergency   situations:
-
 
a
nti-lock   braking   system   (ABS),
-
 
e
lectronic   brake   force   distribution   (EBFD),
-
 
e
mergency   braking   assistance   (EBA).Anti-lock braking system
and electronic brake force
distribution
Linked systems which improve the stability and manoeuvrability   of   your   vehicle   when   braking,  
i

n   particular   on   poor   or   slippery   sur faces.
Activation
The anti-lock braking system comes into operation   automatically   when   there   is   a   risk   of  
w

heel   lock.
Normal
  operation   of   the   ABS   may   make   itself  
f

elt   by   slight   vibration   of   the   brake   pedal.
When
  braking   in   an   emergency,   press  
v

ery   firmly   without   releasing   the  
p

ressure.
Operating fault
If this warning lamp comes on, together   with   the   STOP  and   ABS
warning
  lamps,   accompanied   by   an  
a

udible
 
signal   and   a   message   in   the   screen,   it  
i

ndicates
 
a   malfunction   of   the   electronic   brake  
f

orce
 
distribution   which   could   result   in   loss   of  
c

ontrol
 
of
  the   vehicle   when   braking.
You must stop as soon as it is safe to do so.
When
  replacing   wheels   (tyres   and  
r

ims),   ensure   that   they   conform   to   the  
ma

nufacturer's
 r
ecommendations.
If
  this   warning   lamp   comes   on,  
a

ccompanied   by   an   audible   signal  
a

nd   a   message   in   the   screen,   it  
i

ndicates
 
a   malfunction   of   the   anti-lock   braking  
s

ystem
 
which   could   result   in   loss   of   control   of  
t

he
 
vehicle   when   braking.
In
 
either
 
case,   contact   a   CITROËN   dealer   or   a  
q

ualified
 w
orkshop.

159
Emergency braking assistance
System which, in an emergency, enables you to   obtain   the   optimum   braking   pressure   more  
q

uickly,   thus   reducing   the   stopping   distance.
Activation
It is triggered by the speed at which the brake pedal   is   pressed.
The
  effect   of   this   is   a   reduction   in   the  
r

esistance   of   the   pedal   and   an   increase   in  
b

raking
 e
fficiency.
When
  braking   in   an   emergency,   press  
f

irmly   without   releasing   the   pressure.
Trajectory control systems
Anti-slip regulation (ASR)
and dynamic stability
control (
d
SC)
The anti-slip regulation (also known as traction control)   optimises   traction   to   prevent   skidding  
o

f   the   wheels,   by   acting   on   the   brakes   of   the  
d

riving   wheels   and   on   the   engine.
The electronic stability control acts on the
brake
  of   one   or   more   wheels   and   on   the   engine  
t

o   keep   the   vehicle   on   the   trajectory   required  
b

y   the   driver,   within   the   limits   of   the   laws   of  
p

hysics.Activation
These systems are activated automatically each   time   the   vehicle   is   started.
They
  come   into   operation   in   the   event   of   a   grip

This
  is   indicated   by   flashing   of   this  
w

arning   lamp   in   the   instrument   panel.
Safety

deactivation
In extremely severe conditions (deep snow, mud...),   when   it   is   not   possible   to   move   off,   it  
m

ay   be   useful   to   temporarily   deactivate   the  
s

ystems,   so   that   the   wheels   can   spin   freely   and

Reactivation
These systems are reactivated automatically each   time   the   ignition   is   switched   back   on  
o

r   from   30   mph   (50   km/h)   except   1.6   litre
