2016 CITROEN DS3 CABRIO wheel

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.
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.

151
The alert is maintained until the system is r einitialised.
The
 
loss
 
of
 
pressure
 
detected
 
does
 
not
 a
lways
 
cause
 
visible
 
bulging
 
of
 
the
 
tyre.
 
D

o
 
not
 
satisfy
 
yourself
 
with
 
just
 
a
 
visual
 
c

heck. Before
  reinitialising   the   system,   ensure  
t

hat the pressures of the four tyres are
correct for the use of the vehicle, as
given
  on   the   tyre   pressure   label.
The
  under-inflation   detection   system  
d

oes   not   give   a   warning   if   a   pressure   is  
i

ncorrect   at   the   time   of   reinitialisation.
Under-inflation alert
This is given by fixed illumination of this   warning   lamp,   accompanied   by

Reinitialisation
It is necessary to reinitialise the system every time   one   or   more   tyre   pressure   is   adjusted,   and  
a

A
  label   on   the   middle   pillar,   left   hand   side,   gives

Safety

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.

155
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

Front airbags
System which protects the driver and front passenger   in   the   event   of   a   serious   front   impact  
i

n   order   to   limit   the   risk   of   injury   to   the   head   and  
c

hest.
The
  driver's   airbag   is   fitted   in   the   centre   of   the  
s

teering   wheel;   the   front   passenger's   airbag   is  
f

itted   in   the   dashboard   above   the   glove   box.deployment
The airbags are deployed, except the passenger's   front   airbag   if   it   is   deactivated,  
i

n   the   event   of   a   serious   front   impact   applied  
t

o   all   or   part   of   the   front   impact   zone   A, in
the
  longitudinal   centreline   of   the   vehicle   on   a  
h

orizontal   plane   and   directed   from   the   front   to  
t

he   rear   of   the   vehicle.
The
  front   airbag   inflates   between   the   head-
thorax
  of   the   front   occupant   of   the   vehicle  
a

nd   the   dashboard   to   cushion   their   for ward  
m

ovement.
Safety

169
For the airbags to be fully effective, observe the following safety rules:Front airbags
Do not drive holding the steering wheel by its spokes   or   resting   your   hands   on   the   centre  
p

art   of   the   wheel.
Passengers
  must   not   place   their   feet   on   the  
das

hboard.
Do
  not   smoke   as   deployment   of   the   airbags

Never
  remove   or   pierce   the   steering   wheel   or  
h

it   it   violently.
Do
  not   fit   or   attach   anything   to   the   steering  
w

heel   or   dashboard,   this   could   cause   injuries  
w

ith   deployment   of   the   airbags.
Lateral airbags
Use only approved covers on the seats, compatible   with   the   deployment   the   lateral a

irbags.   For   information   on   the   range   of   seat
 c

overs suitable for your vehicle, you can
contact
  a   CITROËN dealer.
