  vehicle   detected:  
t

he   system   operates   as   a   standard   cruise   control.
Detection
  of   a   vehicle,   at   the   limit   of   the   range   of   the   radar:  
t

he   system   operates   as   a   standard   cruise   control.
"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,
change
  of   lane,   reduction   of   the   speed   of   the   vehicle),   the   system   is   automatically  
pa

used.
The
  display   of   the   deactivation   message   is   accompanied   by   an   audible   signal.
Driving situations and associated alerts
The table below describes the alerts and the messages displayed for the different driving situations.

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,
-
 
v
ehicles   not   running   in   the   middle   of   the  
lan

e,
-
 
v
ehicles   entering   a   corner,
-
 
v
ehicles   changing   lane   at   the   last   moment.
The
 
regulation
 
range
 
is
 
limited
 
to
 
a
 
maximum
 
d

ifference
 
of
 
20
 
mph
 
(30
 
km/h)
 
between
 
the
 
s

peed
 
setting
 
and
 
the
 
speed
 
of
 
the
 
vehicle
 
in
 
f

ront.
 
Above
 
this,
 
the
 
system
 
goes
 
into
 
pause
 
if
 
a

 
safe
 
distance
 
is
 
not
 
maintained.
Severe weather conditions (very heavy
rain, accumulations of snow in front
of the radar) can inter fere with the
operation
 
of
 
the
 
system,
 
resulting
 
in
 
t

he
 
display
 
of
 
the
 
message
 
"SYSTEM
 
I

NACTIVE:
 
Visibility
 
reduced".
 
The

In the event of a fault with the dynamic cruise
control,  you   are   alerted   by   an   audible   signal  
a

nd   the   display   of   the   message   "Driving   aid  
f

unctions
 f
ault".
Have
  the   system   checked   by   a   CITROËN  
d

ealer   or   a   qualified   workshop. When
  the   cruise   control   is   working,   take  
c

are   if   making   a   maintained   press   on  
o

ne   of   the   cruise   control   programmed  
s

peed   modification   buttons:   this   can  
l

ead   to   a   very   quick   change   in   the  
s

peed   of   your   vehicle.
Do not use the dynamic cruise control
on
  slippery   sur faces   or   in   heavy   traffic.
When
  descending   a   steep   hill,   the  
c

ruise control may not be able to
prevent
  the   vehicle   from   exceeding   the  
pro

grammed
 s
peed.
When
  ascending   a   steep   hill   or   when  
t

owing,   it   might   not   be   possible   to   attain  
o

r   maintain   the   programmed   speed.
Operating fault
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.
The use of mats not approved by
CITROËN may inter fere with the
operation
 
of
 
the
 
cruise
 
control.
To
 
avoid
 
any
 
risk
 
of
 
jamming
 
the
 
pedals:
-

e

nsure that mats are secured

Dynamic cruise control with Stop function
The dynamic cruise control is a driving aid that cannot in any circumstances
replace the observation of speed limits
and safe distances, nor the need for
vigilance
  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,
using
  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
ahead.
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
the
 
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
vehicle 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
overtake
  a   slower   vehicle,   the   dynamic   cruise  
c

ontrol allows your vehicle to temporarily
approach the vehicle in front to assist the
overtaking
 ma

noeuvre,
 t
hough
 n
ever
 e
xceeding
 t

he   programmed   speed.

Switching on
The cruise control is switched on manually,
it requires a vehicle speed of between 18 and
112 mph
  (30   and   180   km/h).
An
  automatic   gearbox   must   be   in   position   D
or M . Other wise,
  the   last   setting   made   will   be   used  
w

hen   switching   on   the   system.
Switching   off   the   ignition   cancels   any  
p

rogrammed   speed   setting.
When   the   cruise   control   is   operating,  S
top & Start is automatically
deactivated.
