Flashing of the dashes indicates a fault with the cruise   control.
Have
  it   checked   by   a   CITROËN   dealer   or   a  
q

ualified
 w
orkshop.
Operating faultWhen the cruise control is switched on,
be careful if you maintain the pressure
on  one   of   the   programmed   speed  
c

hanging   buttons:   this   may   result   in   a  
v

ery   rapid   change   in   the   speed   of   your  
v

ehicle.
Do not use the cruise control on
slippery
  roads   or   in   heavy   traffic.
On a steep descent, the cruise control
will not be able to prevent the vehicle
from
  exceeding   the   programmed   speed.
On
  steep   climbs   or   when   towing,   the  
p

rogrammed   speed   may   not   be   reached  
o

r   maintained.
The use of mats not approved by
CITROËN may inter fere with the
operation
  of   the   cruise   control.
To
  avoid   any   risk   of   jamming   of   the  
ped

als:
-

e
nsure that the mat is secured
c o r r e c t l y,
-
 
n
ever   fit   one   mat   on   top   of   another.

Electronic stability control (ESC) incorporating the   following   systems:

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 on
corners, in particular on poor or slippery road
surfaces.
The
  ABS   prevents   wheel   lock   in   the   event   of  
em

ergency
 b
raking.
The
  EBFD   manages   the   braking   pressure  
w

heel   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
increase
  in   the   effectiveness   of   the   braking.
Anti-slip regulation (ASR)
The ASR system (also known as Traction Control) optimises traction in order to limit
wheel
  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
acceleration.
Dynamic stability control (DSC)
If there is a difference between the path
followed by the vehicle and that required by
the driver, the DSC monitors each wheel and
automatically
  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
of
  physics.

Intelligent traction control
system ("Snow motion")
When this warning lamp comes on, coupled with the STOP  and   ABS   warning  
l

amps,   accompanied   by   an   audible   signal  
a

nd   a   message,   it   indicates   that   there  
i

s   a   fault   with   the   electronic   brake   force  
di

stribution
 (
EBFD).
Anti-lock braking system (ABS) and electronic brake force
distribution (EBFD)
The fixed illumination of this warning lamp indicates that there is a fault
with
  the   ABS. Depending
  on   version,   your   vehicle   has   a  s
ystem   to   help   driving   on   snow:   intelligent
traction control.
This system detects situations of difficult
sur 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
provide
  the   best   traction   and   trajectory   control  
f

or   your   vehicle.
The
  use   of   snow   tyres   is   strongly  
r

ecommended   on   sur faces   offering   low   levels  
o

f   adhesion.
When
  changing   wheels   (tyres   and  
r

ims), ensure that these are approved
for
  your   vehicle.
Normal
  operation   of   the   ABS   may   make  
i

tself   felt   by   slight   vibrations   of   the   brake  
ped

al.
In emergency braking, press ver y
firmly and maintain this pressure.
You must stop as soon as it is safe to do so.
In
 
both
 
cases,   have   the   system   checked   by   a  
C

ITROËN   dealer   or   a   qualified   workshop   as  
s

oon
 
as
 
possible.
The
 
vehicle   retains   conventional   braking.   Drive  
c

arefully
 
at   moderate   speed.

Anti-slip regulation (ASR)
Activation
This system is activated automatically each
time  the   vehicle   is   started.
It comes into operation in the event of a
problem
  of   grip.
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
freely
  and   regain   grip.
This
 
is
 
indicated
 
by
 
the
 
flashing
 
of

his
 
warning
 
lamp
 
in
 
the

This system improves safety in the front
seats
  in   the   event   of   a   front   or   side   impact.
