When towing
Distribution of loads
F Distribute the load in the trailer so that the heaviest   items   are   as   close   as   possible   to t

he   axle   and   the   nose   weight   approaches   the
 m

aximum   permitted   without   exceeding   it.
Air density decreases with altitude,
thus
 r

educing
 e
ngine
 p
erformance.
 A

bove 1 000 metres,   the   maximum   towed  
l

oad   must   be   reduced   by   10 %   for   every  
1 0

00 metres   of   altitude.
Side wind
F Take  into   account   the   increased   sensitivity  t
o   side   wind.
For
  more   information   on   weights   (and   the  
t

owed   loads   which   apply   to   your   vehicle)   refer  
t

o   the   corresponding   section.
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   hadlamp   beam   height  
o

f   your   vehicle.
For
  more   information   on   adjusting   the  
h

eadlamp   beam   height,   refer   to   the  
c

orresponding
 s
ection.
The
  rear   parking   sensors   will   be  
d

eactivated   automatically   if   a   genuine  
C

ITROËN   towbar   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 To  deactivate   the   system,   press   this   button  a
gain;   the   warning   lamp   goes   off.
The
  state   of   the   system   remains   in   memory   on  
s

witching   off   the   ignition.
Operating fault
The system is automatically deactivated when   towing   with   a   towbar   approved   by  
CIT

ROËN. The
  system   may   suffer   temporary  
i

nterference in certain weather
conditions   (rain,   hail...).
In   particular,   driving   on   a   wet   sur face  
o

r   moving   from   a   dry   area   to   a   wet   area  
c

an   cause   false   alerts   (for   example,   the  
p

resence   of   a   fog   of   water   droplets   in  
t

he   blind   spot   angle   is   interpreted   as   a  
v

ehicle).
In bad or wintry weather, ensure that
the   sensors   are   not   covered   by   mud,   ice  
o

r   snow.
Take   care   not   to   cover   the   warning   zone  
i

n   the   door   mirrors   or   the   detection  
z

ones   on   the   front   and   rear   bumpers  
w

ith   adhesive   labels   or   other   objects;  
t

hey   may   hamper   the   correct   operation  o
f   the   system.
In   the   event   of   a   fault,   the   warning   lamp   in   the  
b

utton   flashes   then   goes   off.
Have   it   checked   by   a   CITROËN   dealer   or   a  
q

ualified
 w
orkshop.

In addition to the rear parking sensors, the front parking   sensors   are   triggered   when   an   obstacle i

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

ehicle   stops   for   more   than   three   seconds   in
 f

or ward   gear,   if   no   further   obstacles   are   detected
 o

r   when   the   speed   of   the   vehicle   exceeds   6   mph
 (

10   km/h).
Front parking sensors
The function is deactivated by pressing this button.   The   indicator   lamp   in   the   button  
comes
  on.
Pressing
  this   button   again   reactivates   the  
f

unction.   The   indicator   lamp   in   the   button  
goes
  off.
Operating fault
In the event of a malfunction of the   system,   when   reverse   gear  
i

s   engaged   this   warning   lamp   is  
d

isplayed   in   the   instrument   panel  
a

nd/or   a   message   appears   in   the  
s

creen,   accompanied   by   an   audible  
s

ignal   (short   beep).
Contact a CITROËN dealer or a
qualified
 w

orkshop.
The
 
sound
 
emitted
 
by
 
the
 
speaker
 
(front
 
or
 
r

ear)
 
indicates
 
whether
 
the
 
obstacle
 
is
 
in
 
front
 
o

r
 
behind. The function will be deactivated
automatically
 
if
 
a
 
trailer
 
is
 
being
 
towed
 
o

r
 
a
 
bicycle
 
carrier
 
is
 
fitted
 
(vehicle
 
f

itted with a towbar or bicycle carrier
recommended
 
by
 
CITROËN). 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,  
l

orry,
  pneumatic   drill,   etc.)   may   trigger  
t

he
 
audible   signals   of   the   parking  
s

ensor   system.

Towing a trailer
Your vehicle is primarily designed for transporting   people   and   luggage,   but   it   may  
a

lso   be   used   for   towing   a   trailer.
We
  recommend   the   use   of   genuine  
C

ITROËN towbars and their harnesses
that have been tested and approved
from
  the   design   stage   of   your   vehicle,  
a

nd   that   the   fitting   of   the   towbar   is  
e

ntrusted to a CITROËN dealer or a
qualified
 w

orkshop.
If the towbar is not fitted by a
CITROËN
  dealer,   it   must   still   be  
f

itted in accordance with the vehicle
manufacturer's
 i

nstructions.
Very cold climate screen*
* Depending on the country of sale.
