Driving advice
Distribution of loads
F Distribute  the   load   in   the   trailer   so   that  t
he heaviest   items   are   as   close   as  
p

ossible   to   the   axle   and   the   nose   weight  
a

pproaches   the   maximum   permitted  
w

ithout   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  
Brake pads
For information on checking brake disc   wear,   contact   a   CITROËN   dealer

In
  order   to   optimise   the   operation   of

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

Parking brake
If excessive travel or a loss of effectiveness   of   this   system   is

Checking
  this   system   must   be   done   by   a  
C

ITROËN   dealer   or   a   qualified   workshop. To
  avoid   damaging   the   electrical   units,
