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  
in

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
he   following   manoeuvres:
A.
 e

ntry   into   a   parallel   parking   space
B.
 e

xit   from   a   parallel   parking   space
C.
 b

ay
 par
kingThe
  Park   Assist   system   takes   control  
o

f   the   power   steering   for   a   maximum  
o

f   4   manoeuvre   cycles.   The   function  
i

s   deactivated   after   these   4   cycles.  
I

f   you   think   that   your   vehicle   is   not  
p

ositioned   correctly,   you   should   then  
t

ake   control   of   the   steering   to   carry   out  
t

he   manoeuvre.
The
  Park   Assist   system   cannot   work  
w

ith   the   engine   off.

Under-inflation detection
The system monitors the pressures in the four t
yres,   once   the   vehicle   is   moving.
It
  compares   the   information   given   by   the   four  
w

heel   speed   sensors   with   reference values,
which must be reinitialised ever y time the
tyre pressures are adjusted or a wheel
changed .
The
  system   triggers   an   alert   as   soon   as   it  
d

etects   a   drop   in   the   inflation   pressure   of   one  
o

r   more   tyres. The
  under-inflation   detection   system  
d

oes   not   replace   the   need   for   vigilance  
o

n   the   part   of   the   driver.
This
  system   does   not   avoid   the   need   to  
c

heck   the   tyre   pressures   (including   the  
s

pare   wheel)   every   month   as   well   as  
b

efore   a   long   journey.
Driving
  with   under-inflated   tyres   impairs  
r

oad   holding,   extends   braking   distances  
a

nd   causes   premature   tyre   wear,  
p

articularly   under   arduous   condition  
(

high   loading,   high   speed,   long   journey).
System
  which   automatically   checks   the   pressures   of   the   tyres   while   driving.
The   inflation   pressures   defined   for  
y

our   vehicle   can   be   found   on   the   tyre  
p

ressure   label.
See
  the   "Identification   markings"  
s

ection.
Tyre
  pressures   should   be   checked  
w

hen   the   tyres   are   "cold"   (vehicle  
s

topped   for   1   hour   or   after   a   journey   of  
l

ess   than   6   miles   (10   km)   at   moderate  
s

peeds).
Other wise
  (when   hot),   add   0.3   bar   to  
t

he   pressures   shown   on   the   label.
Driving
  with   under-inflated   tyres  
i

ncreases   fuel   consumption.

Safety

Dynamic stability control (DSC)
and anti-slip regulation (ASR)Activation
These systems are activated automatically each   time   the   vehicle   is   started.
As
  soon   as   they   detect   a   problem   of   grip   or  
t

rajectory,   these   systems   act   on   the   operation   if  
t

he   engine   and   brakes.
Deactivation
In exceptional conditions (starting a vehicle which   is   bogged   down,   stuck   in   snow,   on   soft  
g

round...),   it   may   be   advisable   to   deactivate  
t

he   DSC   and   ASR,   so   that   the   wheels   can   turn  
f

reely   and   regain   grip.
This
 
is
 
indicated
 
by
 
flashing
 
of
 
this
 
w

arning
 
lamp
 
in
 
the
 
instrument
 
panel. Reactivate
  the   systems   as   soon   as   the   level   of  
g

rip   permits. F
 
P
ress   this   button.
This
  indicator   lamp   and   the   indicator  
l

amp   in   the   button   come   on.
The
  DSC   and   ASR   systems   no   longer   act  
o

n   the   operation   of   the   engine   and   on   the  
b

rakes   in   the   event   of   a   involuntary   change   of  
t

rajectory.
DSC/ASR
The DSC and ASR systems offer increased s afety   in   normal   driving,   but   they   should   not  
e

ncourage   the   driver   to   take   extra   risks   or   drive  
a

t   high   speed.
It
  is   in   conditions   of   reduced   grip   (rain,   snow,  
i

ce)   that   the   risk   of   loss   of   grip   increases.  
I

t   is   therefore   important   for   your   safety   to  
k

eep   the   DSC   and   ASR   systems   activated  
i

n   all   conditions,   and   particularly   in   difficult  
c

onditions. The
  correct   operation   of   these   systems  
d

epends   on   observation   of   the   manufacturer's  
r

ecommendations   regarding   as   much   the  
w

heels   (tyres   and   rims),   braking   and   electronic  
c

omponents   as   the   assembly   and   repair  
p

rocedures   used   by   CITROËN   dealers.
To   benefit   in   full   from   the   effectiveness   of   the  
D

SC   and   ASR   systems   in   wintry   conditions,  
t

he   vehicle   must   be   fitted   with   four   snow  
t

yres,   allowing   the   the   vehicle   to   retain   neutral  
b

ehaviour   on   the   road.
