Front parking sensors
The sound emitted by the speaker (front or rear) indicates whether the obstacle
is
  in   front   or   behind. The system will be deactivated
automatically
  if   a   trailer   is   being  
t

owed or a bicycle carrier is fitted on
a towbar (vehicle fitted with a towbar
installed
  in   line   with   the   manufacturer's  
r

ecommendations).In bad weather or in winter, ensure
that the sensors are not covered with
mud,
  ice   or   snow.   When   reverse   gear   is  
e

ngaged,   an   audible   signal   (long   beep)  
i

ndicates   that   the   sensors   may   be   dirty.
Certain sound sources (motorcycle,
lorry,
  pneumatic   drill,   etc.)   may   trigger  
t

he   audible   signals   of   the   parking  
s

ensor   system.
As
 
an
 
addition   to   the   rear   parking   sensors,   the  
f

ront
 
parking   sensors   are   triggered   when   an  
o

bstacle is detected in front and the speed of
the
 
vehicle   remains   below   6   mph   (10   km/h).
The
 
front   parking   sensors   are   interrupted   if  
t

he vehicle stops for more than three seconds
in
 
for ward   gear,   if   no   further   obstacles   are  
d

etected or when the speed of the vehicle
exceeds   6   mph   (10   km/h). The   parking   sensors   can   be   deactivated   in   the  
t

ouch   screen   tablet.

Operating fault
In the event of a malfunction of
the
  system,   when   reverse   gear   is

continuously.
This indicator comes on in the

Park Assist
This system provides active assistance with
parking.  It   detects   a   parking   space   then  
o

perates   the   steering   to   park   in   the   space.
It
  operates   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
to
  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  
w

heel   turns   quickly:   do   not   hold   the  
s

teering   wheel,   do   not   place   your   hands  
b

etween   the   spokes   of   the   steering  
w

heel   and   take   care   with   loose   and  
b

ulky   clothing,   scarves,   handbags...  
T

here   is   a   risk   of   injury.
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
vigilance
  on   the   part   of   the   driver.
The driver must remain in control
of
  their   vehicle   ensuring   that   the  
s

pace   remains   clear   throughout   the  
m

anoeuvre.
In some circumstances, the sensors
may not detect small obstacles located
in
  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:

I

f   you   think   that   your   vehicle   is   not  
p

ositioned correctly, you should then
take
  control   of   the   steering   to   carry   out  
t

he   manoeuvre.
The

c

ontact a CITROËN dealer or a qualified
workshop.
Operating faults
In the event of a fault with the power
steering,   this   warning   lamp   flashes   in  
t

he instrument panel, accompanied
by
  a   message.
Contact a CITROËN dealer or a qualified
workshop.
Switching off
If the lateral distance between your
vehicle   and   the   space   is   too   great,   the s

ystem may not be able to measure the
space.
Anything
  projecting   beyond   the   envelope
 o

f the vehicle (a ladder on the roof, for
example)
  is   not   taken   into   account   by   the
 P

ark   Assist   system   during   a   manoeuvre.
In bad weather or in winter, ensure that
the sensors are not covered by road
dirt,
  ice   or   snow.
In the event of a fault, have the system
checked
  by   a   CITROËN   dealer   or   a  
q

ualified
 w
orkshop.
If
 
the
 
system
 
is
 
deactivated
 
during

Under-inflation detection
The system monitors the pressures in the four
tyres,
  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
or
  more   tyres. The under-inflation detection system
does
  not   replace   the   need   for   vigilance  
o

n   the   part   of   the   driver.
This system does not avoid the need to
check
  the   tyre   pressures   (including   the  
s

pare wheel) every month as well as
before
  a   long   journey.
Driving
  with   under-inflated   tyres   impairs  
r

oad   holding,   extends   braking   distances  
a

nd causes premature tyre wear,
particularly under arduous conditions
(high
  loading,   high   speed,   long   journey).
System
  which   automatically   checks   the   pressures   of   the   tyres   while   driving.
The inflation pressures defined for
your vehicle can be found on the tyre
pressure
  label.
For more information on the
Identification markings , refer to the
corresponding
 s

ection.
Tyre
  pressures   should   be   checked  
w

hen the tyres are "cold" (vehicle
stopped
  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.
