Dynamic cruise control with Stop function
The dynamic cruise control is a driving aid that cannot in any circumstances
replace the observation of speed limits
and safe distances, nor the need for
vigilance
  on   the   part   of   the   driver.
It
 
i
s  
r
ecommended   that  
y
ou   always  
k
eep  
y

our   feet   close   to   the   pedals.
The
  driver   must   be   ready   to   take   back  
c

ontrol of their vehicle at any time,
using
  the   brake   or   accelerator   pedal   as  
a

ppropriate.
This
 
system
 
assures
 
two
 
functions:
-
 
a

utomatic
 
regulation
 
of
 
the
 
speed
 
of
 
the
 v
ehicle
 
to
 
a
 
value
 
programmed
 
by
 
the
 d
river,
-
 
a

utomatic
 
adjustment
 
of
 
the
 
distance
 
b

etween your vehicle and the vehicle
ahead.
It
 
manages
 
the
 
acceleration
 
and
 
deceleration
 
o

f
 
the
 
vehicle
 
by
 
automatically
 
acting
 
on
 
the
 
e

ngine
 
and
 
the
 
braking
 
system.
To do this, the system has a radar, located in
the
 
middle
 
of
 
the
 
front
 
bumper,
 
with
 
a
 
maximum
 
r

ange
 
of
 
150
 
metres.
Principles
This system detects a vehicle running in front of y our   vehicle,   travelling   in   the   same   direction.
It automatically adapts the speed of your
vehicle to that of the vehicle in front, to maintain
a
  constant   distance.
If
  the   vehicle   in   front   is   running   more   slowly,   the  
s

ystem   slows,   or   even   stops   your   vehicle,   using  
e

ngine   braking   and   the   braking   system.
If
  the   braking   system   is   used   to   decelerate   the  
v

ehicle,   the   brake   lamps   come   on.
If
  the   vehicle   in   front   accelerates   or   changes  
l

ane,   the   cruise   control   progressively  
a

ccelerates your vehicle to return to the
programmed
 s

peed.
If the driver operates a direction indicator to
overtake
  a   slower   vehicle,   the   dynamic   cruise  
c

ontrol allows your vehicle to temporarily
approach the vehicle in front to assist the
overtaking
 ma

noeuvre,
 t
hough
 n
ever
 e
xceeding
 t

he   programmed   speed.

Switching on
The cruise control is switched on manually,
it requires a vehicle speed of between 18 and
112 mph
  (30   and   180   km/h).
An
  automatic   gearbox   must   be   in   position   D
or M . Other wise,
  the   last   setting   made   will   be   used  
w

hen   switching   on   the   system.
Switching   off   the   ignition   cancels   any  
p

rogrammed   speed   setting.
When   the   cruise   control   is   operating,  S
top & Start is automatically
deactivated.
Pause
The dynamic cruise control can be paused
manually b y:
-
 
a
ction   by   the   driver:
●

●
 
o
n   the   brake   pedal,
●
 
o
n   the   electric   parking   brake   control,
●
 
w
hen   changing   from   D to N with an
automatic
  gearbox.
-

o
r automatically, if operation of the ESC
system
  is   triggered   for   reasons   of   safety.
Following
  braking   of   the   vehicle  
b

ringing   it   to   a   complete   stop,   the  
s

ystem   holds   the   vehicle   stationary   ;  
t

he   cruise   control   is   paused.   The   driver  
s

hould press the accelerator pedal to
move off, then reactivate the system
by
  exceeding   18   mph   (30   km/h)   and  
p

ressing   button   2, 3 or 4 .
If
  the   driver   takes   no   action   following  
t

his   immobilisation,   the   electric   parking

Limits of operation
The system cannot exceed the limits of the laws   of   physics.
It is recommended that the system be
deactivated when the "space-saver" spare
wheel
  is   in   use.
The system should not be activated when
towing
  a   trailer.
In certain critical situations, the system will
encourage
  the   driver   to   immediately   take   back  
c

ontrol:
-

i
f the vehicle in front slows down too much
or too suddenly, and the driver does not
brake,
-

i
f a vehicle comes between your vehicle
and
  the   vehicle   in   front. As
  the   radar's   field   of   detection   is   quite   narrow,  
i

t   is   possible   that   the   system   may   not   detect:
-

v
ehicles of reduced width (motorcycles,
scooters...),
-
 
v
ehicles   not   running   in   the   middle   of   the  
lan

e,
-
 
v
ehicles   entering   a   corner,
-
 
v
ehicles   suddenly   pulling   out.The
  cruise   control   does   not   take   account   of:
-

p
edestrians, cyclists, animals,
-
 
s
tationary   vehicles   (traffic   jam,   red   light,  
b

reakdown...),
-
 
v
ehicles   crossing   a   junction,
-
 
v
ehicles   driving   in   the   opposite   direction.
