Operating fault
Whenever parking, you must apply the parking brake   to   immobilise   the   vehicle,   if   automatic

Parking the vehicle
In all circumstances, ensure that the
gear  selector   is   in   position   P before

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

-
 
t
he   engine   is   needed   to   maintain   a  
c

omfortable   temperature   in   the   passenger  
c

ompartment,

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

as
 
well
  as   the   noise   level   when   stationary.
If your vehicle is fitted with the system, a time

maintain a comfortable temperature in the
passenger  compartment,   it   may   be   necessary  
t

The system can be deactivated at any time,
once
  the   ignition   is   on.
If
  the   engine   is   in   STOP   mode,   it   then   restarts.
The Stop & Start system is automatically
reactivated
  every   time   the   ignition   is  
s

t
 
is
 
strongly
 
recommended
 
that
 
you

system.
For more information on Driving
advice , particularly on flooded roads,
refer
 
to
 
the
 
corresponding
 
section. The Stop & Start system requires a
battery
  of   advanced   technology   and  
sp

ecial
 c
haracteristics.
All
 
work   on   this   type   of   battery   must  
o

nly be done by a CITROËN dealer
or
 
a
  qualified   workshop.

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,
-

  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.

It
 
is
 
recommended
 
that
 
you
 
always
 
keep
 y

our
 
feet
 
close
 
to
 
the
 
pedals.
If
 
the
 
speed
 
setting

(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

 s

etting   and   the   speed   of   the   vehicle   in   front
 b

If the difference between the

great,
  the   speed   cannot   be   adjusted:
