Under-inflation detection
The system monitors the pressures in the four t
yres,   once   the   vehicle   is   moving.
It
  compares   the   information   given   by   the   four  
w

heel   speed   sensors   with   reference values,
which must be reinitialised ever y time the
tyre pressures are adjusted or a wheel
changed .
The
  system   triggers   an   alert   as   soon   as   it  
d

etects   a   drop   in   the   inflation   pressure   of   one  
o

r   more   tyres. The
  under-inflation   detection   system  
d

oes   not   replace   the   need   for   vigilance  
o

n   the   part   of   the   driver.
This   system   does   not   avoid   the   need   to  
c

heck   the   tyre   pressures   (including   the  
s

pare   wheel)   every   month   as   well   as  
b

efore   a   long   journey.
Driving   with   under-inflated   tyres   impairs  
r

oad   holding,   extends   braking   distances  
a

nd   causes   premature   tyre   wear,  p
articularly   under   arduous   condition  (
high   loading,   high   speed,   long   journey).
System
  which   automatically   checks   the   pressures   of   the   tyres   while   driving.
The   inflation   pressures   defined   for  
y

our   vehicle   can   be   found   on   the   tyre  
p

ressure   label.
For   more   information   on   the  
i

dentification   markings,   refer   to   the  c
orresponding s ection.
Tyre   pressures   should   be   checked  
w

hen   the   tyres   are   "cold"   (vehicle  
s

topped   for   1   hour   or   after   a   journey   of  
l

ess   than   6   miles   (10   km)   at   moderate  
s

peeds).
Other wise
  (when   hot),   add   0.3   bar   to  
t

he   pressures   shown   on   the   label.
Driving
  with   under-inflated   tyres  
i

ncreases   fuel   consumption.

When
  the   lighting   is   switched   off   automatically  
(

glamp. In
  good   or   rainy   weather,   both   day  
a

nd   night,   use   of   the   rear   foglamp   is  
p

rohibited.   In   these   situations,   the  
p

ower   of   its   beam   may   dazzle   other  
d

rivers.   It   should   only   be   used   in   fog   or

Do   not   forget   to   switch   off   the   rear  f

Switching off the lamps when
the ignition is switched off
On switching off the ignition, all of the l
amps   turn   off   immediately,   except   for  
d

s   activated.
Switching on the lamps
after the ignition is
switched off
To reactivate the lighting control, rotate the   ring   to   the   "0"  position   -   lamps   off,  
t

On
  opening   the   driver's   door   a  
c

ontinuous   audible   signal   warns   the

Active City Brake
Active City B rake  i s  a  d riving  a ssistance  s ystem  t
hat   aims   to   avoid   a   frontal   collision   or   reduce  
t

he   speed   of   an   impact   if   the   driver   does   not  
r

eact   or   reacts   too   late   (brake   application   too  
l

ate). 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  
a

n   optical   instrument   (magnifying   glass,  
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 and a camera located at the   top   of   the   windscreen,   this   system   detects  
a

  vehicle   running   in   the   same   direction   or  
s

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

s   operated   automatically   to   reduce   the   speed  
o

f   impact   or   to   help   avoid   a   collision   with   the  
v

ehicle
 a
head.
Conditions for activation
Active City Brake only operates if the following
c onditions   are   met:
●

●
 
t

●
 
t

-

(

15 and   140   km/h),
-
 
t
he   difference   in   speed   between   your

Never leave accumulations of snow or any   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  
g

enerate   a   detection.
Operating limits
The system  o nly  d etects  v ehicles  (cars,  lorries) t
hat   are   stationary   or   moving   in   the   same  
d

irection   as   your   vehicle. In
  difficult   weather   conditions   (very  
h

eavy   rain,   snow,   fog,   hail...),   braking  
d

istances   increase,   which   can   reduce  
t

he   ability   of   the   system   to   avoid   a  
c

ollision.
The
  driver   must   therefore   remain  
par

ticularly
 v
igilant.
The
  system   is   not   triggered   or   is   interrupted   if  
t

he
 d
river:
-
 
a
ccelerates   strongly   (even   if   the   speed  
l

imiter   is   on),
-
 
o
r   turns   the   steering   wheel   suddenly  
(

avoiding
 m
anoeuvre).
Detection
  capability   is   less   effective   if:
-
 
y
ou   are   driving   on   roads   with   pronounced  
b

ends   and/or   on   roads   in   poor   condition,
-
 
y
our   vehicle   is   excessively   loaded,   as  
t

his   changes   the   horizontal   attitude   of   the  
v

ehicle.
-
 
y
our   vehicle   skids.
It
  does   not   detect   small   vehicles  
(

bicycles,   motorcycles),   pedestrians   or  
a

nimals,   nor   non-reflective   stationary  
ob

jects.Unwanted triggering of the system
It is possible for the system to detect a risk of imminent   collision   and   start   working,   in   the  
fo

llowing
 c
onditions
 in par
ticular:
-
 
d
etection   of   an   object   located   close   to   the  
e

dge   of   the   road   entering   a   corner   (safety  
b

arrier,   lamp   post   or   road   sign),
-
 
d
etection   of   a   structure   located   at   the   top  
o

r   bottom   of   a   steep   slope   (advertising  
h

oarding,   steet   lighting),
-
 
d
etection   of   reflective   objects   (central  
r

eservation...)   in   the   road,
-
 
d
etection   of   the   upper   bar   of   a   bridge   or   a  
t

raffic   light   gantry,
