 l

ever on position N
 
and   put   your   foot   on   the   brake

It
  is   then   necessary   to   switch   off   the   ignition   and

w

hich   a   CITROËN   dealer   is   able   to  
pro

Before
  doing   anything   under   the

s

ystem   to   avoid   any   risk   of   injury  
r

esulting   from   automatic   operation   of

TART   mode.
Maintenance
This system requires a 12 V battery with a special   specification   and   technology   (reference  
n

umbers   available   from   CITROËN   dealers).
Fitting
  a   battery   not   listed   by   CITROËN  
i

ntroduces   the   risk   of   malfunction   of   the  
s

ystem.
For
  charging,   use   a   12   V   charger   and   do   not  
r

everse   the   polarity.

active cruise control
This systems 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   ahead   to   be  
m

aintained.Principles of operation
Using a radar with a range of about 100 metres, located   at   the   front   of   the   vehicle,   this   system  
d

etects   a   vehicle   running   in   front   of   your  
v

ehicle.
It
  automatically   adapts   the   speed   of   the   vehicle  
t

o   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   cruise  
c

ontrol   is   automatically   deactivated.   The  
d

river   is   then   alerted   by   an   audible   signal,  
a

ccompanied   by   a   message.
If
  the   vehicle   in   front   accelerates   or   changes  
l

ane,   the   active   cruise   control   progressively  
a

ccelerates your vehicle to return to the
programmed
 s

peed.
If
  the   driver   operates   a   direction   indicator   to  
t

he   left   (left   hand   drive)   or   the   right   (right   hand  
d

rive),   to   overtake   a   slower   vehicle,   the   active  
c

ruise   control   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.
Choice of the type of cruise control
If you want to use the standard cruise control, it is possible to deactivate the active cruise
control
  in   the   the   touch   screen   tablet.

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

The active cruise control uses only engine braking   to   slow   the   vehicle.   Consequently   the  
v

ehicle   looses   speed   slowly,   as   when   releasing  
t

he   accelerator   pedal.
The

Park Assist
This system provides active assistance with parking,   detecting   a   parking   space   then  
c

ontrolling   the   steering   to   park   in   the   space.
It
  controls   the   steering   while   the   driver  
m

anages   the   accelerator,   brakes,   gears   and  
c

lutch   (manual   gearbox).   During   phases   of  
e

ntry   into   and   exit   from   a   parking   space,   the  
s

ystem   provides   visual   and   audible   information  
t

o   the   driver   in   order   to   make   the   manoeuvres  
s

afe.   It   may   be   necessary   to   move   for wards  
a

nd   backwards   more   than   once. During
  a   manoeuvre   the   steering   wheel  
t

urns   quickly:   do   not   hold   the   steering  
w

heel,   do   not   place   your   hand   between  
t

he   spokes   of   the   steering   wheel   and  
t

ake   care   with   loose   and   bulky   clothing,  
s

carves,   handbags...   There   is   a   risk   of

jury.
When
  Park   Assist   is   activated,   it  
p

revents   a   change   to   STOP   mode   of  
S

top   &   Start.   In   STOP   mode,   activation  
o

f   Park   Assist   restarts   the   engine.
The
  Park   Assist   system   cannot   in   any  
c

ircumstances   replace   the   need   for  
v

igilance   on   the   part   of   the   driver.
The
  driver   must   remain   in   control  
o

f   their   vehicle   ensuring   that   the  
s

pace   remains   clear   throughout   the  
m

anoeuvre.
In
  some   circumstances,   the   sensors  
m

ay   not   detect   small   obstacles   located  
i

n   their   blind   spots.
The
  driver   can   take   control   at   any   time   by  
g

ripping   the   steering   wheel. The
  Park   Assist   system   provides   assistance   for  t
