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.

Brake wear depends on the style of   driving,   particularly   in   the   case  
o

f   vehicles   used   in   town,   over   short  
d

istances.   It   may   be   necessary   to  
h

ave
 
the
 
condition   of   the   brakes   checked,   even  
b

etween
 v
ehicle
 s
ervices.
Unless
 
there   is   a   leak   in   the   circuit,   a   drop   in  
t

he
 
brake
  fluid   level   indicates   that   the   brake  
p

ads
 
are
 
worn.
Brake pads
For information on checking brake d isc   wear,   contact   a   CITROËN   dealer  
o

r   a   qualified   workshop.
Brake disc wear
Only use products recommended by CITROËN   or   products   of   equivalent  
q

uality

In
  order   to   optimise   the   operation   of  
u

nits   as   important   as   those   in   the  
b

raking   system,   CITROËN   selects   and  
o

ffers   very   specific   products.
After
  washing   the   vehicle,   dampness,  
o

r   in   wintry   conditions,   ice   can   form  
o

n   the   brake   discs   and   pads:   braking  
e

fficiency   may   be   reduced.   Make   light  
b

rake   applications   to   dry   and   defrost  
t

he   brakes.
Electric parking brake
