Citroen GRAND C4 PICASSO RHD 2016 2.G Owner's Manual

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
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

r

elative   speeds   of   your   vehicle   and   the  
v

ehicle   in   front   and   the   inter-vehicle   time  
se

-
 
w
hen   the   distance   between   your   vehicle  
a

nd   the   one   in   front   becomes   too   small,
-
 
w

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

 d

ifference   between   the   programmed   speed

Detection

"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

utomatic   deactivation   of   the   system   is   imminent.
"Cruise control
paused" If
  the   system   exceeds   the   limit   of   speed   adjustment   possible   by   the   system   and  
i

n   the   absence   of   any   reaction   by   the   driver   (operation   of   the   direction   indicator,  
c

hange   of   lane,   reduction   of   the   speed   of   the   vehicle),   the   system   is   automatically  
pa

used.
The

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

r

estored.   The   message   "Activation  
n

ot   possible,   conditions   unsuitable"  
i

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:
-

-
 
v
ehicles   of   reduced   width,   such   as  
m

Dynamic cruise control with Stop function
The dynamic cruise control is a driving aid   that   cannot   in   any   circumstances  
r

eplace   the   observation   of   speed   limits  
a

nd   safe   distances,   nor   the   need   for  
v

igilance   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,  
u

sing   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
 
a

head.
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
 
t

he
 
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  
v

ehicle   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  
ov

ertake   a   slower   vehicle,   the   dynamic   cruise  
c

ontrol   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.
