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.
When
  braking   in   an   emergency,   press  
f

irmly   without   releasing   the   pressure.
Trajectory control systems
Anti-slip regulation (ASR)
and electronic stability
programme (ESP)
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   programme   acts   on   the  
b

rake   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

blem.
This
  is   indicated   by   flashing   of   this

Active City Brake
Active City Brakeis a driving assistance system that   aims   to   avoid   a   frontal   collision   or   reduce  
t

he   speed   of   an   impact   if   the   driver   does  
n

ot   take   sufficient   action   (inadequate   brake  
a

pplication).
This system is designed to improve driving safety.
I t   remains   the   driver's   responsibility   to c

ontinuously   monitor   the   state   of   the   traffic   and
 t

o assess the distances and relative speeds of
other
 v

ehicle.
Active City Brakecan in no circumstances replace   the   need   for   vigilance   on   the   part   of t

he
 d
river.
never look at the laser sensor through an optical 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
only
  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 Brakeonly 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.

Operating limits
The system only detects vehicles that are stationary   or   moving   in   the   same   direction   as  
y

our   vehicle.
It
  does   not   detect   small   vehicles  
(

bicycles,   motorcycles),   pedestrians   or  
a

nimals,   nor   non-reflective   stationary  
ob

jects. In difficult weather conditions (very
heavy
  rain,   snow,   fog,   hail...),   braking  
d

istances increase, which can reduce
the
  ability   of   the   system   to   avoid   a  
c

ollision.
The
  driver   must   therefore   remain  
par

ticularly
 v
igilant.
Never
  leave   accumulations   of   snow   or  
a

ny   object   projecting   above   the   bonnet  
o

r   in   front   of   the   roof:   this   might   fall   into  
t

he field of vision of the sensor and
generate
  a   detection.
The
  system   is   not   triggered   or   is   interrupted   if  t
he d river:
-
 
a
ccelerates   strongly
-
 
o
r   turns   the   steering   wheel   suddenly  
(

avoiding
 m
anoeuvre).

Safety

The driver must ensure that passengers use the seat belts correctly and that they are all
restrained
  securely   before   setting   off.
Wherever you are seated in the vehicle,
always fasten your seat belt, even for short
journeys.
Do
  not   interchange   the   seat   belt   buckles   as  
t

hey   will   not   fulfil   their   role   fully.
The seat belts are fitted with an inertia reel
permitting
  automatic   adjustment   of   the   length  
o

f   the   strap   to   your   size.   The   seat   belt   is  
s

towed   automatically   when   not   in   use.
be

fore and after use, ensure that the seat
belt
  is   reeled   in   correctly.
The
  lower   part   of   the   strap   must   be  
p

ositioned   as   low   as   possible   on   the   pelvis.
The
  upper   part   must   be   positioned   in   the

In the event of an impact
depending on the nature and seriousness
of the impact ,
  the   pretensioning   device   may  
b

e deployed before and independently of the
airbags.
  Deployment   of   the   pretensioners  
i

ctivation   of   the   pyrotechnic   cartridge  
i

ncorporated   in   the   system.
In
  all   cases,   the   airbag   warning   lamp   comes   on.

Airbags
System designed to contribute towards improving   the   safety   of   the   occupants   (with  
t

he   exception   of   the   rear   centre   passenger)  
i

n   the   event   of   violent   collisions.   The   airbags  
s

upplement   the   action   of   the   force-limiting  
s

eat   belts   (with   the   exception   of   the   centre   rear  
p

assenger).
If a collision occurs, the electronic detectors
record
  and   analyse   the   front   and   side   impacts  
s

ustained   in   the   impact   detection   zones:
-
 
i
n   the   case   of   a   serious   impact,   the   airbags  
a

re deployed instantly and contribute
towards better protection of the occupants
of
  the   vehicle   (with   the   exception   of   the  
r

ear   centre   passenger);   immediately   after  
t

he   impact,   the   airbags   deflate   rapidly   so  
t

hat   they   do   not   hinder   visibility   or   the   exit  
o

f the occupants,
-
 
i
n   the   case   of   a   minor   or   rear   impact   or   in  
c

ertain   roll-over   conditions,   the   airbags  
m

ay   not   be   deployed;   the   seat   belt  
a

lone   contributes   towards   ensuring   your  
p

rotection   in   these   situations. This
  equipment   will   only   deploy   once.  
I

f   a   second   impact   occurs   (during   the  
s

ame   or   a   subsequent   accident),   the  
a

irbag   will   not   be   deployed   again.
Impact detection zones
A. Front  impact   zone.
B. S ide   impact   zone.
Deployment
  of   one   or   more   of   the  
a

irbags   is   accompanied   by   a   slight  
e

mission   of   smoke   and   a   noise,   due  
t

o the activation of the pyrotechnic
cartridge
  incorporated   in   the   system.
This
  smoke   is   not   harmful,   but   sensitive  
i

ndividuals   may   experience   slight  
ir

ritation.
The noise of detonation related to the
deployment
  of   one   or   more   airbags  
m

ay   result   in   a   slight   loss   of   hearing   for  
a

  short   time.
The airbags do not operate when the
ignition is switched off.

t

he   new   position.
This
  warning   lamp   comes   on   in   the
 i

nstrument   panel   when   the   ignition   is
 o

n   and   until   the   airbag   is   re-activated.To assure the safety of your child,
the
  passenger's   front   airbag   must  
b

e deactivated when you install a
"rear   facing"   child   seat   on   the   front

Reactivation
When you remove a child seat that has b
een   fitted   "rear wards   facing",   turn   switch   to  
t

he "ON"
 
position   to   re-activate   the   airbag   and  
s

o   assure   the   safety   of   your   front   passenger   in  
t

he   event   of   an   impact.
