When towing
Distribution of loads
F Distribute  the   load   in   the   trailer   so   that   the h
eaviest   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   engine   per formance.   Above  
1 0

00 metres,   the   maximum   towed   load   must  
b

e   reduced   by   10 %   for   every   1 000   metres   of  
al

titude.
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  
a

udible   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

S

TOP
 
warning   lamp   come   on,  
s

top   the   vehicle   and   switch   off  
t

he   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  
h

eight   of   your   vehicle.
For
  more   information   on   Adjusting the
headlamp beam height , refer to the

Fatigue detection system
Depending on version, the "Driving time warning   system"   may   be   combined   with   the  
"

Fatigue   detection   system".
Using
  a   camera   placed   at   the   top   of   the  
w

indscreen,   the   system   assesses   the   driver's  
l

evel   of   vigilance   by   identifying   variations   in  
t

rajectory   compared   to   the   lane   markings.
This
  system   is   particularly   suited   to   fast   roads  
(

speed   higher   than   40   mph   (65   km/h)).Once
  the   system   considers   that   the   behaviour  o
f   the   vehicle   suggests   a   certain   level   of   fatigue  
o

r   inattention   by   the   driver,   it   triggers   the   first  
l

evel   of   alert.
The
  driver   is   then   alerted   by   the   message  
"Ta

k e c a r e !",
  accompanied   by   an   audible  
s

ignal.
After
  three   first   level   alerts,   the   system   triggers  
a

  new   alert   with   the   message   "Take a break! ",
accompanied
  by   a   more   pronounced   audible  
s

ignal. In
  certain   driving   conditions   (poor   road  
s

ur face   or   strong   winds),   the   system  
m

ay   give   alerts   independent   of   the  
d

river's   level   of   vigilance.
The   following   situations   may   inter fere  
w

ith   operation   of   the   system   or   prevent  
i

t   working:
-  
p
oor   visibility   (inadequate   lighting  
o

f   the   roadway,   falling   snow,   heavy
