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
mode
This indicator lamp comes on in the instrument
panel  and   the   engine   goes   into   standby  
au

tomatically:
-

w
ith a manual gearbox , at speeds below
12
  mph   (20   km/h),   or   vehicle   stationary  
(

with   PureTech   130,   THP   165   and  
B

lueHDi 100, 115 and 120 versions), when
you
  place   the   gear   lever   in   neutral,   and   you  
r

elease the clutch pedal,
-

w
ith an automatic gearbox , with the
vehicle stationary, when you press the
brake
  pedal   or   place   the   gear   selector   lever  
i

n position N . Never
  refuel   with   the   engine   in   STOP  
m

ode;   you   must   switch   off   the   ignition  
w

ith   the   START/STOP   button.
For
  your   comfort,   during   parking  
m

anoeuvres, STOP mode is not
available for a few seconds after
coming
  out   of   reverse   gear.
The Stop & Start system does not affect
the functionality of the vehicle, such as
for
  example,   braking,   power   steering...
Special cases: STOP mode not
available
STOP mode is not invoked when:
-  t he   driver's   door   is   open,
-
 
t
he   driver's   seat   belt   is   not   fastened,
-
 
t
he   vehicle   has   not   exceeded   6   mph  
(10
  km/h)   since   the   last   engine   start   using  
t

he   START/STOP   button,
-
 
t
he   electric   parking   brake   is   applied   or  
be

ing
 a
pplied,
-
 
t
he   engine   is   needed   to   maintain   a  
c

omfortable   temperature   in   the   passenger  
c

ompartment,
-
 
d
emisting   is   selected,
-
 
s
ome   special   conditions   (battery   charge,  
e

ngine   temperature,   braking   assistance,  
a

mbient   temperature...)   where   the   engine   is  
n

eeded   to   assure   control   of   a   system.
In this case, this indicator lamp flashes
for  a   few   seconds   then   goes   off.
This operation is perfectly normal.
Per fect
 
for
 
urban
 
use,
 
the

system
 
reduces
 
fuel
 
consumption
 
and
 
exhaust
 
emissions
 
as
 
well
  as   the   noise   level   when   stationary.
If your vehicle is fitted with the system, a time
counter calculates the sum of the periods in
STOP
 
mode
 
during
 
a
 
journey.
 
It
 
resets
 
itself

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
detects
  a   vehicle   running   in   front   of   your  
v

ehicle.
It automatically adapts the speed of the vehicle
to
  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
dynamic
  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
to
  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
temporarily approach the vehicle in front to
assist
  the   overtaking   manoeuvre,   though   never  
e

xceeding   the   programmed   speed.
Driving

161
C4-Picasso-II_en_Chap04_conduite_ed01-2016
The dynamic cruise control is switched on
manually:   it   requires   that   the   speed   of   the  
v

ehicle be between 25 and 90 mph (40 and
150 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,
-
position 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
manually o r a utomatically:
-
 
b
y   pressing   button   4,
-
 
b
y   pressing   the   brake   pedal,
-

i
n the event of operation of the ESC, for
safety reasons,
-

i
n the event of operation of the electric
parking
  brake   control   lever,
-

w
hen an inter-vehicle time threshold is
reached
  (calculated   according   to   the  
r

elative speeds of your vehicle and the
vehicle in front and the inter-vehicle time
setting
 c

hosen),
-

w
hen the distance between your vehicle
and the one in front becomes too small,
-

w
hen the speed of the vehicle in front is too
low,
-

w
hen the speed of your vehicle becomes
too
  low.
The dynamic cruise control cannot in any
circumstances replace the observation
of

igilance
 o

n
 
the
 
part
 
of
 
the
 
driver.
It
 
is
 
recommended
 
that
 
you
 
always
 
keep
 y

our
 
feet
 
close
 
to
 
the
 
pedals.
If
 
the
 
speed
 
setting
 
selected
 
is
 
above
 
9

0
 
mph
 
(150
 
km/h),
 
the
 
system
 
switches
 
t

o standard cruise control operation,
with
 
no
 
adjustment
 
of
 
the
 
inter-vehicle
 
s

afe
 
distance
 
(a
 
message
 
appears
 
in
 
t

he
 
instrument
 
panel). The
  inter-vehicle   time   setting   is   kept   in  
m

emory   on   switching   off   the   ignition.
The dynamic cruise control operates by
day
 
and
 
at
 
night,
 
in
 
fog
 
or
 
in
 
moderate
 
r

ainfall.
The system does not act on the braking s ystem,   but   works   only   with   engine   braking.
The
  regulation   range   is   limited:   there   will
 n

o   longer   be   any   adjustment   of   speed   if   the
 d

ifference   between   the   programmed   speed
 s

etting   and   the   speed   of   the   vehicle   in   front
 b

ecomes   too   high   (18   mph   (30   km/h)).
If the difference between the
programmed  speed   setting   and   the  
s

peed of the vehicle in front is too
great,
  the   speed   cannot   be   adjusted:  
t

he cruise control is automatically
deactivated.

"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

When the dynamic cruise control is
automatically paused, it can only be
reactivated when safe conditions are
restored.  The   message   "Activation  
no

t possible, conditions unsuitable"
is displayed while reactivation is not
possible.
When the conditions allow, it is
recommended that the system be
reactivated
  by   pressing   button   2 or 3,
which
  will   make   the   current   speed   of  
y

our vehicle the new cruise speed
setting,
  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
current
  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
or too suddenly, and the driver does not
brake,
-

i
f a vehicle comes between your vehicle
and the vehicle in front,
-

i
f the system does not slow the vehicle
enough
  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
motorcycles,
  for   example,
-
