Stop & Start
The Stop & Start system puts the engine temporarily into standby - STOP mode - during stops in the traffic (red lights, traffic jams, or other...). The engine   restarts   automatically   -   START   mode   -   as   soon   as   you   want   to   move   off.   The   restart   takes   place   instantly,   quickly   and   silently.
Operation
Going into engine STOP

Dynamic cruise control
System that allows, in addition to maintaining your vehicle's speed at a value that you have defined, the inter-vehicle time you have selected between your   vehicle   and   the   one   in   front   to   be   maintained.
Principles of operation
Using a radar with a range of about 100 metres, located   at   the   front   of   the   vehicle,   this   system  
d

etects   a   vehicle   running   in   front   of   your  
v

ehicle.
It
  automatically   adapts   the   speed   of   the   vehicle  
t

o   that   of   the   vehicle   in   front.
If
  the   vehicle   in   front   is   running   more   slowly,  
t

he   system   progressively   reduces   the   speed   of  
y

our   vehicle   using   just   engine   braking   (as   if   the  
d

river   had   pressed   the   "-"
  button).
If
  your   vehicle   is   too   close   to   or   approaching  
t

oo   quickly   the   vehicle   in   front,   the   dynamic  
c

ruise   control   is   automatically   deactivated.  
T

he   driver   is   then   alerted   by   an   audible   signal,  
a

ccompanied   by   a   message.
Choice of the type of cruise control
The choice between the "dynamic" and "standard"   cruise   control   is   done   in   the   Driving
menu.
F

I
n the Driving
 
menu,   select   the   "Driving
assistance " tab, then "Dynamic cruise
control"
  to   activate   or   deactivate   the  
d

ynamic   cruise   control.
For
  more   information   on   the   Cruise
control ,
  refer   to   the   corresponding  
s

ection.F

P
lace the cruise control
thumbwheel
  at   "CRUISE". If
  the   vehicle   in   front   accelerates   or   changes  l
ane,   the   dynamic   cruise   control   progressively  
a

ccelerates your vehicle to return to the
programmed
 s

peed.
If
  the   driver   operates   a   direction   indicator  
t

o   the   left   (left   hand   drive)   or   the   right   (right  
h

and   drive),   to   overtake   a   slower   vehicle,   the  
d

ynamic   cruise   control   allows   your   vehicle   to  
t

emporarily   approach   the   vehicle   in   front   to  
a

ssist   the   overtaking   manoeuvre,   though   never  
e

xceeding   the   programmed   speed.
Driving

159
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

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

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

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  
(

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

  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
