Electronic stability control (ESC)
Definitions
Anti-lock braking system (ABS)
and electronic brake force
distribution (EBFD)
This system improves the stability and manoeuvrability   of   your   vehicle   when   braking  
a

nd   contributes   towards   improved   control   in  
c

orners,   in   particular   on   poor   or   slippery   road  
su

rfaces.
The
  ABS   prevents   wheel   lock   in   the   event   of  
em

ergency
 b
raking.
The
  electronic   brake   force   distribution   system  
m

anages   the   braking   pressure   wheel   by   wheel.
Emergency braking assistance
(EBA)
In an emergency, this system enables you to reach   the   optimum   braking   pressure   more  
q

uickly   and   therefore   reduce   the   stopping  
di

stance.
It
  is   triggered   according   to   the   speed   at   which  
t

he   brake   pedal   is   pressed.   This   is   felt   by   a  
r

eduction   in   the   resistance   of   the   pedal   and   an  
i

ncrease   in   the   effectiveness   of   the   braking.
Anti-slip regulation (ASR)
The ASR system (also known as Traction Control)   optimises   traction   in   order   to   limit  
w

heel   slip   by   acting   on   the   brakes   of   the   driving  
w

heels   and   on   the   engine.   It   also   improves  
t

he   directional   stability   of   the   vehicle   on  
a

cceleration.
Dynamic stability control (DSC)
If there is a difference between the path followed   by   the   vehicle   and   that   required   by  
t

he   driver,   the   DSC   monitors   each   wheel   and  
a

utomatically   acts   on   the   brake   of   one   or   more  
w

heels   and   on   the   engine   to   return   the   vehicle  
t

o   the   required   path,   within   the   limits   of   the   laws  
o

f   physics.
Safety

216
Dynamic stability control (DSC)
and anti-slip regulation (ASR)Activation
These systems are activated automatically each   time   the   vehicle   is   started.
As
  soon   as   they   detect   a   problem   of   grip   or  
t

rajectory,   these   systems   act   on   the   operation   if  
t

he   engine   and   brakes.
Deactivation
In exceptional conditions (starting a vehicle which   is   bogged   down,   stuck   in   snow,   on   soft  
g

round...),   it   may   be   advisable   to   deactivate  
t

he   DSC   and   ASR,   so   that   the   wheels   can   turn  
f

reely   and   regain   grip.
This
 
is
 
indicated
 
by
 
flashing
 
of
 
this
 
w

arning
 
lamp
 
in
 
the
 
instrument
 
panel. Reactivate
  the   systems   as   soon   as   the   level   of  
g

rip   permits. F
 
P
ress   this   button.
This
  indicator   lamp   and   the   indicator  
l

amp   in   the   button   come   on.
The
  DSC   and   ASR   systems   no   longer   act  
o

n   the   operation   of   the   engine   and   on   the  
b

rakes   in   the   event   of   a   involuntary   change   of  
t

rajectory.
DSC/ASR
The DSC and ASR systems offer increased s afety   in   normal   driving,   but   they   should   not  
e

ncourage   the   driver   to   take   extra   risks   or   drive  
a

t   high   speed.
It
  is   in   conditions   of   reduced   grip   (rain,   snow,  
i

ce)   that   the   risk   of   loss   of   grip   increases.  
I

t   is   therefore   important   for   your   safety   to  
k

eep   the   DSC   and   ASR   systems   activated  
i

n   all   conditions,   and   particularly   in   difficult  
c

onditions. The
  correct   operation   of   these   systems  
d

epends   on   observation   of   the   manufacturer's  
r

ecommendations   regarding   as   much   the  
w

heels   (tyres   and   rims),   braking   and   electronic  
c

omponents   as   the   assembly   and   repair  
p

rocedures   used   by   CITROËN   dealers.
To   benefit   in   full   from   the   effectiveness   of   the  
D

SC   and   ASR   systems   in   wintry   conditions,  
t

he   vehicle   must   be   fitted   with   four   snow  
t

yres,   allowing   the   the   vehicle   to   retain   neutral  
b

ehaviour   on   the   road.

Access to the battery
Procedure for starting the engine using another battery or charging a discharged battery.
T he presence of this label, in particular
with
  the   Stop   &   Start   system,   indicates  
t

he   use   of   a   12   V   lead-acid   battery   with  
s

pecial
 t
echnology
 a
nd

pecification;
 t

he   involvement   of   a   CITROËN   dealer  
o

r   a   qualified   workshop   is   essential  
w

hen   replacing   or   disconnecting   the  
b

attery.
After
  refitting   the   battery,   the   Stop & Start
 s

ystem   will   only   be   active   after   a
 c

ontinuous   period   of   immobilisation   of   the
 v

ehicle,   a   period   which   depends   on   the
 c

limatic   conditions   and   the   state   of   charge
 o

f   the   battery   (up   to   about   8   hours). When
  your   vehicle's   battery   is   discharged,   the  
e

ngine   can   be   started   using   a   slave   battery  
(

external   or   on   another   vehicle)   and   jump   lead  
c

ables.
Starting using another
battery
First check that the slave battery has a nominal   voltage   of   12   V   and   a   capacity  
a

t   least   equal   to   that   of   the   discharged  
b

attery.
Do
  not   try   to   start   the   engine   by  
c

onnecting   a   battery   charger.
Do
  not   disconnect   the   (+)   terminal   when  
t

he   engine   is   running.

Before disconnecting the battery
Wait 2 minutes after switching off the ignition before   disconnecting   the   battery.
Close
  the   windows   and   the   doors   before  
d

isconnecting   the   battery.
Following reconnection
of the battery
Following reconnection of the battery, switch on t
he   ignition   and   wait   1   minute   before   starting   to  
p

ermit   initialisation   of   the   electronic   systems.
