The dynamic cruise control is switched on
m anually:   it   requires   that   the   speed   of   the  
v

ehicle   be   between   25   and   90   mph   (40   and  
1

50 km/h),   as   well   as   the   engagement   of:
-
 
f
ourth   gear   or   higher   with   a   manual  
g

earbox,
-
 
s
econd   gear   or   higher   with   an   automatic  
g

earbox   in   manual   mode,
-
 
p
osition   D   with   an   automatic   gearbox.
The
  system   remains   active   after   changing   gear  
o

n   vehicles   with   a   manual   gearbox   and  
Stop
  &   Start.
General points
The dynamic cruise control can be paused
m anually o r a utomatically:
-
 
b

-
 
b
y   pressing   the   brake   pedal,
-
 
i
n   the   event   of   operation   of   the   ESC,   for  
s

afety reasons,
-
 
i
n   the   event   of   operation   of   the   electric  
p

arking   brake   control   lever,
-
 
w
hen   an   inter-vehicle   time   threshold   is

r

elative   speeds   of   your   vehicle   and   the  
v

The system does not act on the braking s ystem,   but   works   only   with   engine   braking.
The

"SPEED ADJUSTED" Detection
  of   a   vehicle   that   is   too   close   or   running   at   a   speed   lower   than   your  
v

ehicle's   cruise   speed   setting.
The
  system   uses   engine   braking   to   slow   your   vehicle   and   then   hold   it   at   the   speed   of  
t

he   vehicle   in   front   so   as   to   maintain   the   programmed   inter-vehicle   time.
The
  regulation   range   is   limited   to   a   maximum   difference   of   20   mph   (30   km/h)  
b

etween   the   speed   setting   and   the   speed   of   the   vehicle   ahead.
"SPEED ADJUSTED" When
  the   adjusted   speed   reaches   the   control   limit   (speed   setting   -   20   mph  
(

30 km/h)),   the   adjusted   speed   flashes   together   with   the   speed   setting,   to   signal   that  
a

"Cruise control

When the dynamic cruise control is automatically   paused,   it   can   only   be

s   displayed   while   reactivation   is   not  
p

ossible.
When
  the   conditions   allow,   it   is  
r

ecommended   that   the   system   be  
r

eactivated   by   pressing   button   2 or 3,
which
  will   make   the   current   speed   of  
y

our   vehicle   the   new   cruise   speed  
s

etting,   rather   than   by   pressing   button   4
(on/pause)
  which   reactivates   the   system  
u

sing   the   old   cruise   speed   setting,  
w

hich   may   be   very   different   from   the  
c

urrent   speed   of   your   vehicle. The
  dynamic   cruise   control   uses   only   engine  b
raking   to   slow   the   vehicle.   Consequently   the  
v

ehicle   loses   speed   slowly,   as   when   releasing  
t

he   accelerator   pedal.
The
  system   is   paused   automatically:
-
 
i
f   the   vehicle   in   front   slows   down   too   much  
o

r   too   suddenly,   and   the   driver   does   not  
b

rake,
-
 
i
f   a   vehicle   comes   between   your   vehicle  
a

nd   the   vehicle   in   front,
-
 
i
f   the   system   does   not   slow   the   vehicle  
e

nough   to   continue   to   maintain   a   safe  
d

istance,   for   example   when   descending   a  
s

teep   hill.
Limits of operation
As the radar's field of view is quite narrow, it is possible   that   the   system   may   not   detect:
The
  cruise   control   does   not   take   account   of:
-
 
s
tationary   vehicles,
-
 
v
ehicles   driving   in   the   opposite   direction.
-
 
v
ehicles   of   reduced   width,   such   as  
m

-
 
v
ehicles   not   running   in   the   middle   of   the  
lan

Park Assist
This system provides active assistance with parking.   It   detects   a   parking   space   then  
o

perates   the   steering   to   park   in   the   space.
It
  operates   the   steering   while   the   driver  
m

anages   the   accelerator,   brakes,   gears   and  
c

lutch   (manual   gearbox).   During   phases   of  
e

ntry   into   and   exit   from   a   parking   space,   the  
s

ystem   provides   visual   and   audible   information  
t

o   the   driver   in   order   to   make   the   manoeuvres  
s

afe.   It   may   be   necessary   to   move   for wards  
a

nd   backwards   more   than   once. During
  a   manoeuvre   the   steering  
w

heel   turns   quickly:   do   not   hold   the  
s

teering   wheel,   do   not   place   your   hands  
b

etween   the   spokes   of   the   steering  
w

heel   and   take   care   with   loose   and  
b

ulky   clothing,   scarves,   handbags...  
T

here   is   a   risk   of   injury.
When
  Park   Assist   is   activated,   it  
p

revents   a   change   to   STOP   mode   of  
S

top   &   Start.   In   STOP   mode,   activation  
o

f   Park   Assist   restarts   the   engine.
The
  Park   Assist   system   cannot   in   any  
c

ircumstances   replace   the   need   for  
v

igilance   on   the   part   of   the   driver.
The
  driver   must   remain   in   control  
o

f   their   vehicle   ensuring   that   the  
s

pace   remains   clear   throughout   the  
m

anoeuvre.
In
  some   circumstances,   the   sensors  
m

ay   not   detect   small   obstacles   located  
i

n   their   blind   spots.
The
  driver   can   take   control   at   any   time   by  
g

ripping   the   steering   wheel. The
  Park   Assist   system   provides   assistance   for  t
he   following   manoeuvres:
