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  
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
  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  
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.

Dynamic stability control
(DSC) and anti-slip regulation
(ASR)The DSC system offers exceptional safety   in   normal   driving,   but   this   should  
n

ot   encourage   the   driver   to   take   extra  
r

isks   or   drive   at   high   speed.
The
  correct   operation   of   the   system

t

he   braking   components,   the   electronic  
c

After
  an   impact,   have   the   system  
c

hecked   by   a   CITROËN   dealer   or   a  
q

ualified
 w
orkshop.
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   system,   so   that   the   wheels   can   move  
f

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

lamp
 
in

Grip control
Special patented traction control system which improves   traction   on   snow,   mud   and   sand.
This
  system,   the   operation   of   which   has   been  
o

ptimised   for   each   situation,   allows   you   to  
m

anoeuvre   in   most   conditions   of   poor   grip  
(

a

  compromise   between   safety,   adhesion   and  
t

raction.   These   tyres   work   equally   well   in   winter  
a

A
  five-position   selector   allows   you   to   choose

A few driving recommendations
Observe the driving regulations at all times 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  
r

eact   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.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  
s

talling.   In   all   cases,   do   not   exceed   6   mph  
(

10 km/h),
-  d o   not   stop   and   do   not   switch   off   the  e
ngine.
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.
Important!
Never drive with the parking brake applied   -   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  
c

ontact with   the   hot   exhaust   system   -  
R

isk   of   fire!
Never
  leave   a   vehicle   unsupervised  
w

ith   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.

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

he   axle   and   the   nose   weight   approaches  
t

he   maximum   permitted   without  
e

xceeding it.
Air
  density   decreases   with   altitude,   thus  
r

educing   engine   per formance.   Above  
1 0

00 metres,   the   maximum   towed   load   must  
b

e   reduced   by   10 %   for   every   1 000   metres   of  
al

titude.
For
  more   information   on   weights   (and   the  
t

owed   loads   which   apply   to   your   vehicle)   refer  
t

o   the   corresponding   section.
Side wind
F Take  into   account   the   increased   sensitivity  t
o   side   wind.
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. F
 
I
f   the   warning   lamp   and   the  
S

TOP
 
warning   lamp   come   on,  
s

top   the   vehicle   and   switch   off  
t

he   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.
