Towing a trailer
We recommend the use of genuine CITROËN   towbars   and   their   harnesses  
t

hat   have   been   tested   and   approved  
f

rom   the   design   stage   of   your   vehicle,  
a

nd   that   the   fitting   of   the   towbar   is  
e

ntrusted   to   a   CITROËN   dealer   or   a  
q

ualified
 w
orkshop.
If
  the   towbar   is   not   fitted   by   a  
C

ITROËN   dealer,   it   must   still   be  
f

itted   in   accordance   with   the   vehicle  
m

anufacturer's
 i
nstructions.
Your
 
vehicle   is   primarily   designed   for  
t

ransporting   people   and   luggage,   but   it   may  
a

lso
 
be   used   for   towing   a   trailer. Driving   with   a   trailer   places   greater  
d

emands   on   the   towing   vehicle   and   the  
d

river   must   take   particular   care.

Driving advice
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.
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  
t

he   engine   as   soon   as   possible.
Braking
Towing a trailer increases the braking distance.
T o   avoid   overheating   of   the   brakes   on   a   long  
m

ountain   type   of   descent,   the   use   of   engine  
b

raking   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.
