Hill start assist
System which holds your vehicle temporarily (approximately   2   seconds)   when   starting   on   a  
s

lope,   the   time   it   takes   to   move   your   foot   from  
t

he   brake   pedal   to   the   accelerator   pedal.
This
  function   is   only   active   when:
-
 
t
he   vehicle   is   completely   stationary,   with  
y

our   foot   on   the   brake   pedal,
-
 
c
ertain   conditions   on   a   slope   are   met,
-
 
w
ith   the   driver’s   door   closed.
The hill start assist function cannot be
deactivated.
On an ascending slope, with the vehicle
stationary, the vehicle is held momentarily
when you release the brake pedal:
-
 
p
rovided   you   are   in   automated   mode  
(

position
 A)

  or   in   manual   mode   (position   M)
 
w

ith   an   electronic   gearbox.
Do
  not   leave   the   vehicle   while   it   is  
b

eing   held   in   the   hill   start   assist   phase.
If
  you   need   to   leave   the   vehicle   with  
t

he   engine   running,   manually   apply  
t

he   parking   brake   then   ensure   that   the  
p

arking   brake   warning   lamp   is   on   (not  
f

lashing)   in   the   instrument   panel.Operation
On a descending slope, with the vehicle
stationary and reverse gear engaged, the
vehicle is held momentarily when you
release the brake pedal.
Operating fault
If a malfunction of the system occurs, these warning   lamps   come   on.   Contact   a   CITROËN

Braking assistance systems
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,  
i

n   particular   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.
When
  braking   in   an   emergency,   press  
v

ery   firmly   without   releasing   the  
p

ressure.
Operating fault
If this warning lamp comes on, together   with   the   STOP  and   ABS
warning
  lamps,   accompanied   by   an  
a

udible
 
signal   and   a   message   in   the   screen,   it  
i

ndicates
 
a   malfunction   of   the   electronic   brake  
f

orce
 
distribution   which   could   result   in   loss   of  
c

ontrol
 
of
  the   vehicle   when   braking.
You must stop as soon as it is safe to do so.
When
  replacing   wheels   (tyres   and  
r

ims),   ensure   that   they   conform   to   the  
ma

nufacturer's
 r
ecommendations.
If
  this   warning   lamp   comes   on,  
a

ccompanied   by   an   audible   signal  
a

nd   a   message   in   the   screen,   it  
i

ndicates
 
a   malfunction   of   the   anti-lock   braking  
s

ystem
 
which   could   result   in   loss   of   control   of  
t

he
 
vehicle   when   braking.
In
 
either
 
case,   contact   a   CITROËN   dealer   or   a  
q

ualified
 w
orkshop.

155
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  
r

esistance   of   the   pedal   and   an   increase   in  
b

raking
 e
fficiency.
When
  braking   in   an   emergency,   press  
f

irmly   without   releasing   the   pressure.
Trajectory control systems
Anti-slip regulation (ASR)
and dynamic stability
control (
d
SC)
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.

Active City Brake
Active City Brake is a driving assistance system   that   aims   to   avoid   a   frontal   collision  
o

r   reduce   the   speed   of   an   impact   if   the   driver  
d

oes   not   react   sufficiently   (inadequate   brake  
a

pplication). This
  system   is   designed   to   improve  
d

riving   safety.
It
  remains   the   driver's   responsibility   to  
c

ontinuously   monitor   the   state   of   the  
t

raffic   and   to   assess   the   distances   and  
r

elative   speeds   of   other   vehicles.
Active
  City   Brake   can   in   no  
c

ircumstances   replace   the   need   for  
v

igilance   on   the   part   of   the   driver.
Never
  look   at   the   laser   sensor   through  
an o

ptical
 in
strument
 (
magnifying
 g
lass,
 m

icroscope...)   at   a   distance   of   less   than  
1

0   centimetres:   risk   of   eye   injury.Automatic
  braking   occurs   later   than   if  
d

one   by   the   driver,   so   as   to   intervene  
o

nly   when   there   is   a   high   risk   of  
c

ollision.Principle
Using a laser sensor located at the top of the windscreen,   this   system   detects   a   vehicle  
r

unning   in   the   same   direction   or   stationary  
a

head   of   your   vehicle.
When
  necessary,   the   vehicle's   braking   system  
i

s   operated   automatically   to   avoid   a   collision  
w

ith   the   vehicle   ahead.
Conditions for activation
Active City Brake only operates if the following conditions   are   met:
●
 
i
gnition   on,
●
 
t
he   vehicle   is   in   a   for ward   gear,
●
 
s
peed   is   between   about   3   and   18   mph  
(5
  and   30   km/h),
●
 
t
he   braking   assistance   systems   (ABS,  
E

BFD,   emergency   braking   assistance)   are  
n

ot faulty,
●
 
t
he   trajectory   control   systems   (ASR,   DSC)  
a

re   not   deactivated   or   faulty,
●
 
t
he   vehicle   is   not   in   a   tight   corner,
●
 
t
he   system   has   not   been   triggered   during  
t

he   previous   10   seconds.
Safety

Operation
When your vehicle is too close to or
approaches  the   vehicle   ahead   too   quickly   the  
s

ystem   automatically   applies   the   brakes   to  
a

void   a   collision.
The
  collision   can   be   avoided   automatically   if   the
 d

ifference   in   speed   between   your   vehicle   and   the
 v

ehicle   ahead   does   not   exceed   9   mph   (15   km/h).
Above
  this   threshold,   the   system   will   do   what
 i

s   possible   to   avoid   or   reduce   the   accident   by
 l

owering   the   speed   of   impact.
The
  automatic   braking   may   bring   the   vehicle   to  
a

  complete   stop   if   the   situation   requires   it.
In
  this   case,   the   vehicle   is   held   stationary  
t

emporarily   (for   about   1.5   seconds)   to   allow  
t

he   driver   to   take   back   control   by   pressing   the  
b

rake
 ped
al.
You
  are   then   alerted   by   the   display   of   a  
m

essage.
The
  brake   lamps   on   your   vehicle   come   on   to  
w

arn   other   road   users.
After
  an   impact,   the   system   is  
a

utomatically   put   out   of   service:   it   no

rates.
You
  must   go   to   a   CITROËN   dealer   or   a  
q

ualified   workshop   to   have   the   system  
m

ade   operational   again.
During
  automatic   braking,   the   driver  
c

an   always   obtain   a   higher   rate   of  
d

eceleration   than   that   controlled   by   the  
s

ystem,   by   pressing   firmly   on   the   brake  
ped

al.
The
  triggering   of   the   system   may   cause  
t

he   engine   to   stall,   unless   the   driver  
d

epresses   the   clutch   pedal   quickly  
e

nough   during   automatic   braking.
deactivation
The system is deactivated in the vehicle configuration   menu,   accessible   with   the   ignition  
o

n.
Its
  state   is   memorised   when   the   ignition   is  
s

witched off. When
  the   system   is   deactivated,   a  
m

essage   is   displayed   every   time   the  
i

gnition   is   switched   on,   to   warn   you.

207
Removing a wheel
Parking the vehicle
Immobilise the vehicle where it does not   block   traffic:   the   ground   must   be  
l

evel,   stable   and   not   slippery.
Apply
  the   parking   brake,   switch   off   the  
i

gnition   and   engage   first   gear*   to   lock  
t

he   wheels.
If
  necessary,   place   a   chock   under   the  
w

heel   diagonally   opposite   the   wheel   to  
be c

hanged.
It
  is   imperative   that   you   ensure   that   the  
o

ccupants   get   out   of   the   vehicle   and  
w

ait   where   they   are   safe.

It is strongly recommended that before you   leave,   you   practise   fitting   the   snow  
c

hains   on   a   level   and   dry   sur face.
Snow chains
In wintry conditions, snow chains improve traction as well as the behaviour of the vehicle when braking.
T he   snow   chains   must   be   fitted   only  
t

o   the   front   wheels.   They   must   never  
b

e   fitted   to   "space-saver"   type   spare  
w

heels.
Take
  account   of   the   legislation   in   force  
i

n your country on the use of snow
chains
  and   the   maximum   running

Avoid
  driving   with   snow   chains   on  
r

oads   that   have   been   cleared   of   snow,  
t

o   avoid   damaging   your   vehicle's   tyres  
a

nd   the   road   sur face.   If   your   vehicle  
i

s   fitted   with   alloy   wheels,   check   that  
n

o   part   of   the   chain   or   its   fixings   is   in  
c

ontact   with   the   wheel   rim.
