t

he   vehicle   exceeds   6   mph   (10   km/h).
Pressing   the   central   locking   button   unlocks   the  
v

ehicle.
Above
  6   mph   (10   km/h),   this   unlocking   is  
t

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,   in p

articular   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.
Operating fault
If this warning lamp comes on, accompanied   by   an   audible   signal  
a

nd   a   message   in   the   screen,   it  
i

ndicates   a   malfunction   of   the   anti-
lock
  braking   system   which   could  
r

esult in loss of control of the vehicle
when
 b

raking.
If
  this   warning   lamp   comes   on,
 t

ogether   with   the   STOP and ABS
warning
  lamps,   accompanied   by   an
 a

udible   signal   and   a   message   in   the
 s

creen,   it   indicates   a   malfunction   of
 t

he   electronic   brake   force   distribution
 w

hich could result in loss of control of
the
  vehicle   when   braking.
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
resistance of the pedal and an increase in
braking
 e

fficiency.
You must stop as soon as it is safe to do so.
In either case, contact a CITROËN dealer or a
qualified
 w

orkshop.
When
 
braking
 
in
 
an
 
emergency,
 
press
 
v

ery
 
firmly
 
without
 
releasing
 
the
 
p

ressure. When
  braking   in   an   emergency,   press  
f

irmly   without   releasing   the   pressure.
When
 
replacing
 
wheels
 
(tyres
 
and
 
r

ims),
 
ensure
 
that
 
they
 
conform
 
to
 
the

Trajectory control systems
Anti-slip regulation (ASR)
and dynamic stability
control (DSC)
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  
o

r
 t
rajectory
 pro
blem.
This
  is   indicated   by   flashing   of   this  
w

arning   lamp   in   the   instrument   panel.
Intelligent traction control
system ("Snow motion")
Deactivation
In extremely severe conditions (deep snow, mud,   ...),   if   you   are   unable   to   move   off,   it   may  
b

e   useful   to   temporarily   deactivate   these  
s

ystems   so   that   the   wheels   can   spin   freely   and  
a

llow   the   vehicle   to   move.
F
 
P
ress   this   button,   located   near   the   steering  
w

heel.
If
  the   indicator   lamp   in   the   button   comes   on,   this
 i

ndicates   that   these   systems   are   deactivated.
Depending
 
on
 
version,
 
your
 
vehicle
 
has
 
a
 
s

ystem
 
to
 
help
 
driving
 
on

This
 
system
 
detects
 
situations
 
of
 
difficult
 
s

ur face
 
adhesion
 
that
 
could
 
make
 
it
 
difficult
 
to
 
m

ove
 
off
 
or
 
make
 
progress
 
on
 
deep
 
fresh
 
snow
 
o

r
 
compacted
 
snow.
In these situations, the intelligent traction
control
 

limits
 
the
 
amount
 
of
 
wheel
 
slip
 
to
 
p

rovide
 
the
 
best
 
traction
 
and
 
trajectory
 
control
 
f

It  is   recommended   that   the   systems   be  
r

eactivated   as   soon   as   possible.
The
 
use
 
of
 
snow
