In the event of a fault in STOP mode, the vehicle
may
  stall.
All
  of   the   instrument   panel   warning   lamps   come on.
Depending on version, an alert message may also   be   displayed,   asking   you   to   place   the   gear  
s

elector lever at position N and put your foot on
the
  brake   pedal.
It is then necessary to switch off the ignition and start   the   engine   again   using   the   "START/STOP" b

utton.
In the event of a fault with the system,
this indicator lamp flashes for a few
moments then comes on continuously,
accompanied
  by   a   message.

Operating fault
As a safety measure, do not use the system if
the  brake   lamps   are   faulty.
Do not use the system if the front bumper is
damaged. In the event of a fault with the cruise
control, you are alerted by the
illumination
  of   this   warning   lamp  
a

nd   the   display   of   a   message   in   the  
in

strument panel, accompanied by an
audible
 s
ignal.
The cruise control operates by day and at
night,
 
in
 
fog
 
or
 
moderate
 
rainfall.
However,
 
it
 
is
 
strongly
 
recommended
 
that
 
y

ou
 
always
 
keep
 
a
 
safe
 
distance
 
from
 
v

ehicles
 
ahead,
 
according
 
to
 
the
 
driving
 
c

onditions, the weather and the road
sur face.
Use the cruise control only where the
driving
 
conditions
 
allow
 
running
 
at
 
a
 
c

onstant speed and at an adequate safe
distance.
Do not use the cruise control in urban
areas,
 
heavy
 
traffic,
 
on
 
winding
 
or
 
steep
 
r

oads
 
or
 
on
 
slippery
 
or
 
flooded
 
sur faces.
In certain circumstances, it may not
be

Collision risk alert
System providing a warning to the driver that their vehicle is at risk of collision with the vehicle in front.
T he   collision   risk   alert   system   can   be   activated  
o

r   deactivated   in   the   touch   screen   tablet.
In the Driving menu, select the " Settings" tab,
then " Driving aid " and "Collision risk alert ".
This
  system   has   been   designed   to  
i

mprove   driving   safety.
It is the responsibility of the driver to
keep
  a   constant   check   on   the   state   of  
t

he traffic, to assess the relative speed
and
  distance   of   other   vehicles.
The
  collision   risk   alert   system   can   never  
r

eplace   the   need   for   vigilance   on   the  
p

art   of   the   driver.
This system operates from 20 mph
(30 km/h),
  only   when   other   vehicles   are  
r

unning   in   the   same   direction   as   your  
v

ehicle;   the   system   does   not   detect  
s

tationary   objects.   A   radar   is   fitted   at  
t

he   front   of   the   vehicle. The alert thresholds determine how you want to
be
  alerted   to   the   presence   of   a   vehicle   running  
i

n   front   of   you.
You
  can   choose   from   three   thresholds:
-
 
1
:   "Distant ".
-
 
2
:   "Normal ".
-
 
3
:   "Close ".
Setting the thresholds for
the alert
This function can be deactivated
permanently by a CITROËN dealer
or
  a   qualified   workshop.
In the Driving menu, select the " Settings" tab,
then " Driving aid " and select the symbol for
the " Collision risk alert "
  function:
F
 
m
odify   the   alert   threshold   using   the   arrows  
o

r   the   cursor.
Driving

177
C4-Picasso-II_en_Chap04_conduite_ed01-2016
The change from one level of alert to   the   next   takes   place   if   the   driving  
c

onditions   do   not   change   (speed  
u

nchanged,   no   change   of   lane...)
Severe weather conditions (very heavy
rain, accumulation of snow in front
of the radar) may inter fere with the
operation
  of   the   system,   resulting   in  
t

he   display   of   the   message   "SYSTEM  
I

NACTIVE:   Reduced   visibility".   The  
s

ystem remains unavailable until the
message
 d

isappears.
If
  the   speed   of   your   vehicle   is   too   high  
w

hen   approaching   another   vehicle,   the  
f

irst   level   of   alert   may   not   be   displayed:  
t

he level 2 alert may be displayed
di r e c t l y.
On the other hand, the level 1 alert
is
  never   displayed   with   the   triggering  
t

hreshold   3   (close).
Alerts
According to the collision risk detected by the system and the alert threshold chosen, three
levels
  of   alert   can   be   triggered.
Level 1 :
  visual   alert   only   (orange)  
i

ndicating   that   the   vehicle   in   front   is  
v

ery   close.   The   message   "Vehicle
close "
  is   displayed.
Level 2 :
  visual   (red)   and   audible  
a

lerts   indicating   that   a   collision   is  
i

mminent.   The   message   "Brake! " is
displayed.
This level of alert is based on the inter-vehicle
time
  between   your   vehicle   and   the   one   in   front.
This level of alert is based on a time before
collision.
  It   takes   account   of   the   vehicle  
d

ynamics, the speed of your vehicle and
the
  speed   of   the   vehicle   in   front,   the   driving  
c

onditions, the situation with your vehicle
(cornering,
  pedals   pressed,   etc.)   to   trigger   the  
a

lert   at   the   right   moment.
Operating fault
In the event of a fault, you are alerted
by  the   display   of   the   Service   warning  
l

amp,   accompanied   by   a   message.
Consult a CITROËN dealer or a
qualified
 w

orkshop.
The operation of the radar, located in
the front bumper, may be disturbed by
accumulations
  of   grime   (dust,   mud...)  
o

r in certain weather conditions (snow,
ice...).
The
  message   "SYSTEM   INACTIVE:  
V

isibility   reduced"   is   displayed   to   signal  
t

hat the system has been put into
st a n dby.
Clean
  the   front   bumper   regularly.

Assisted lane departure warning system
Using a camera placed at the top of the windscreen to identify lane markings on the ground, this systems corrects the trajectory of the vehicle while alerting   the   driver   if   it   detects   a   risk   of   involuntary   crossing   of   a   line.
This
  system   is   particularly   useful   on   motor ways   and   main   roads.
The
  assisted   lane   departure   warning
 s

ystem cannot, in any circumstances,

 o

f   the   driver.
The driver remains responsible for the
vehicle
  in   all   circumstances.   The   system
 h

elps   the   driver   only   when   there   is   a   risk
 o

f   the   vehicle   involuntarily   wandering
 f

rom   the   lane   it   is   being   driven   on.
 I

t   does   not   manage   the   safe   driving
 d

istance, the speed of the vehicle or the
brakes.
The
  driver   must   hold   the   steering   wheel
 i

n   a   way   that   allows   control   to   be   taken
 b

ack   in   circumstances   where   the   system
 i

s not able to intervene (where there are
no
  lane   markings,   for   example).
It
  is   necessary   to   observe   the   driving
 r

egulations   and   take   a   break   every
 t

wo hours.
Operation
Conditions for operation
The speed of the vehicle must be between 40
and
  112   mph   (65   and   180   km/h).
The
  carriageway   must   have   at   least   one   lane  
m

arking   (solid   or   broken)   on   the   ground.
The driver must hold the wheel with both
hands.
The
  change   of   trajectory   is   not   accompanied   by  
o

peration   of   the   direction   indicators.
The
  ESC   system   must   be   activated. Once
  the   system   identifies   a   risk   of   the   vehicle  i
nvoluntarily   crossing   one   of   the   lane   markings  
d

etected,   it   makes   the   correction   to   the  
t

rajectory   necessary   to   return   the   vehicle   to   its  
in

itial
 pa
th.
The
  driver   will   then   notice   a   turning   movement  
o

f   the   steering   wheel.
This
  warning   lamp   flashes   during  
t

rajectory
 c
orrection.
If the driver wishes to maintain the
trajectory
  of   the   vehicle,   they   can  
p

revent   the   correction   by   keeping   a   firm  
g

rip   on   the   wheel   (during   an   avoiding  
m

anoeuvre,   for   example).
The correction is interrupted if the
direction
  indicators   are   operated.
