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
 
ma

nufacturer's
 r

ecommendations.

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.

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

This
 
system
 
detects
 
situations
 
of
 
difficult

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

slip
 
to
 
p

rovide
 
the
 
best
 
traction
 
and
 
trajectory

It  is   recommended   that   the   systems   be  
r

eactivated   as   soon   as   possible.
The
 
use
 
of
 
snow
 
tyres
 
is
 
strongly

Driving recommendations
Observe the driving regulations and remain vigilant   whatever   the   traffic   conditions.
Pay
  close   attention   to   the   traffic   and   keep   your  
h

ands on the wheel so that you are ready to
react
  at   any   time   to   any   eventuality.
On
  a   long   journey,   a   break   every   two   hours   is  
s

trongly
 re
commended.
In
  difficult   weather,   drive   smoothly,   anticipate  
t

he   need   to   brake   and   increase   the   distance  
f

rom   other   vehicles.
Driving on flooded roads
We strongly advise against driving on flooded roads,   as   this   could   cause   serious   damage  
t

o   the   engine   or   gearbox,   as   well   as   to   the  
e

lectrical   systems   of   your   vehicle.
Important!If you are obliged to drive through water:
-  
c
heck   that   the   depth   of   water   does   not  
e

xceed   15   cm,   taking   account   of   waves  
t

hat   might   be   generated   by   other   users,
-
 
d
eactivate   the   Stop   &   Start   system,
-

d
rive as slowly as possible without
stalling.
  In   all   cases,   do   not   exceed   6   mph  
(

10 km/h),
-

d
o not stop and do not switch off the
engine. Never
  drive   with   the   parking   brake  
a

pplied   -   Risk   of   overheating   and  
d

amage   to   the   braking   system!
Do
  not   park   or   run   the   engine   when  
s

tationary   in   areas   where   inflammable  
s

ubstances   and   materials   (dry   grass,  
d

ead   leaves...)   might   come   into   contact  
w

ith   the   hot   exhaust   system   -   Risk   of  
f

ire!
Never leave a vehicle unsupervised
with
  the   engine   running.   If   you   have  
t

o   leave   your   vehicle   with   the   engine  
r

unning,   apply   the   parking   brake  
a

nd   put   the   gearbox   into   neutral   or  
p

osition

N or P,
  depending   on   the   type  
o

f   gearbox.
On
  leaving   the   flooded   road,   as   soon   as  
c

ircumstances   allow,   make   several   light   brake  
a

pplications   to   dry   the   brake   discs   and   pads.
If in doubt on the state of your vehicle, contact
a
  CITROËN   dealer   or   a   qualified   workshop.

When towing
Distribution of loads
F Distribute the load in the trailer so that the heaviest   items   are   as   close   as   possible   to t

he   axle   and   the   nose   weight   approaches   the
 m

aximum   permitted   without   exceeding   it.
Air density decreases with altitude,
thus
 r

educing
 e
ngine
 p
erformance.
 A

bove 1 000 metres,   the   maximum   towed  
l

oad   must   be   reduced   by   10 %   for   every  
1 0

00 metres   of   altitude.
Side wind
F Take  into   account   the   increased   sensitivity  t
o   side   wind.
For
  more   information   on   weights   (and   the  
t

owed   loads   which   apply   to   your   vehicle)   refer  
t

o   the   corresponding   section.

f   the   warning   lamp   and   the  
S

TOP
 
warning   lamp   come   on,  
s

top the vehicle and switch off
the   engine   as   soon   as   possible.
Braking
Towing a trailer increases the braking distance.
T o   avoid   overheating   of   the   brakes,   the   use   of  
e

ngine   braking   is   recommended.
Ty r e s
F Check  the   tyre   pressures   of   the   towing  v
ehicle   and   of   the   trailer,   observing   the  
re

commended
 p
ressures.
Lighting
F Check  the   electrical   lighting   and   signalling  o
n   the   trailer   and   the   hadlamp   beam   height  
o

f   your   vehicle.
For
  more   information   on   adjusting   the  
h

eadlamp   beam   height,   refer   to   the  
c

orresponding
 s
ection.
The
  rear   parking   sensors   will   be  
d

eactivated   automatically   if   a   genuine  
C

ITROËN   towbar   is   used.
Cooling
Towing a trailer on a slope increases the temperature   of   the   coolant.
As
  the   fan   is   electrically   controlled,   its   cooling  
c

apacity   is   not   dependent   on   the   engine   speed.
F
 
T
o   lower   the   engine   speed,   reduce   your  
s

peed.
The
  maximum   towed   load   on   a   long   incline  
d

epends   on   the   gradient   and   the   ambient  
t

emperature.
In
  all   cases,   keep   a   check   on   the   coolant  
t

emperature.
