When towing
Distribution of loads
F Distribute the load in the trailer so that the heaviest items are as close as possible to
the
  axle   and   the   nose   weight   approaches   the
 m

aximum   permitted   without   exceeding   it.
Air density decreases with altitude, thus
reducing
  engine   per formance.   Above  
1 0

00 metres,   the   maximum   towed   load   must  
b

e reduced by 10 % for every 1 000 metres of
altitude.
Side wind
F Take   into   account   the   increased   sensitivity  t
o   side   wind.
For more information on Weights
, refer
to   the   corresponding   section.
The   rear   parking   sensors   will   be  
d

eactivated automatically to avoid the
audible
  signal   if   a   genuine   CITROËN  
t

owbar   is   used.
Cooling
Towing a trailer on a slope increases the temperature   of   the   coolant.
As
  the   fan   is   electrically   controlled,   its   cooling  
c

apacity   is   not   dependent   on   the   engine   speed.
F
 
T
o   lower   the   engine   speed,   reduce   your  
s

peed.
The
  maximum   towed   load   on   a   long   incline  
d

epends   on   the   gradient   and   the   ambient  
t

emperature.
In
  all   cases,   keep   a   check   on   the   coolant  
t

emperature. F
 
I
f   the   warning   lamp   and   the  
S

TOP
 
warning   lamp   come   on,  
s

top the vehicle and switch off
the
  engine   as   soon   as   possible.
Braking
Towing a trailer increases the braking distance.
T o   avoid   overheating   of   the   brakes,   the   use   of  
e

ngine   braking   is   recommended.
Ty r e s
F Check  the   tyre   pressures   of   the   towing  v
ehicle   and   of   the   trailer,   observing   the  
re

commended
 p
ressures.
Lighting
F Check  the   electrical   lighting   and   signalling  o
n the trailer and the headlamp beam
height
  of   your   vehicle.
For more information on Adjusting the
headlamp beam height , refer to the
corresponding

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,

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.

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:

lectronic   brake   force   distribution   (EBFD),
-
 
e
mergency   braking   assistance   (EBA),
-

ynamic   stability   control   (DSC).
Electronic stability control (ESC)
Definitions
Anti-lock braking system (ABS)
and electronic brake force
distribution (EBFD)
This system improves the stability and
manoeuvrability  of   your   vehicle   when   braking  
a

nd contributes towards improved control on
corners, in particular on poor or slippery road
surfaces.
The
  ABS   prevents   wheel   lock   in   the   event   of  
em

ergency
 b
raking.
The
  EBFD   manages   the   braking   pressure  
w

heel   by   wheel.
Emergency braking assistance
(EBA)
In an emergency, this system enables you to reach   the   optimum   braking   pressure   more  
q

uickly   and   therefore   reduce   the   stopping  
di

stance.
It
  is   triggered   according   to   the   speed   at   which  
t

he   brake   pedal   is   pressed.   This   is   felt   by   a  
r

eduction in the resistance of the pedal and an
increase
  in   the   effectiveness   of   the   braking.
Anti-slip regulation (ASR)
The ASR system (also known as Traction Control) optimises traction in order to limit
wheel
  slip   by   acting   on   the   brakes   of   the   driving  
w

heels   and   on   the   engine.   It   also   improves  
t

he directional stability of the vehicle on
acceleration.
Dynamic stability control (DSC)
If there is a difference between the path
followed by the vehicle and that required by
the driver, the DSC monitors each wheel and
automatically
  acts   on   the   brake   of   one   or   more  
w

heels   and   on   the   engine   to   return   the   vehicle  
t

o the required path, within the limits of the laws
of
  physics.

problem
  of   grip.
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
freely
  and   regain   grip.
