Cruise control "CRUISE"
System which automatically maintains the speed of the vehicle at the value programmed by the driver, without any action on the accelerator pedal.
The cruise control system cannot, in any circumstances, replace the need to observe speed limits, nor can it replace the need for vigilance on the part of the driver.
Y ou   are   advised   to   keep   your   feet   near   the   pedals   at   all   times.
Switching on the cruise control requires a
minimum   vehicle   speed   of   25   mph   (40   km/h).

active cruise control
This systems 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   ahead   to   be  
m

aintained.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   cruise  
c

ontrol   is   automatically   deactivated.   The  
d

river   is   then   alerted   by   an   audible   signal,  
a

ccompanied   by   a   message.
If
  the   vehicle   in   front   accelerates   or   changes  
l

ane,   the   active   cruise   control   progressively  
a

ccelerates your vehicle to return to the
programmed
 s

peed.
If
  the   driver   operates   a   direction   indicator   to  
t

he   left   (left   hand   drive)   or   the   right   (right   hand  
d

rive),   to   overtake   a   slower   vehicle,   the   active  
c

ruise   control   allows   your   vehicle   to   temporarily  
a

pproach the vehicle in front to assist the
overtaking
 ma

noeuvre,
 t
hough
 n
ever
 e
xceeding
 t

he   programmed   speed.
