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.

The petrol or Diesel engine of your vehicle is fitted   with   a   catalytic   converter,   a   device   which  
h

elps   to   reduce   the   level   of   harmful   emissions  
i

For petrol engines, you must use unleaded
fuel.
The
  filler   neck   is   narrower,   allowing   only  
u

nleaded   petrol   nozzles   to   be   introduced.
If you have put in the wrong fuel
for your vehicle, you must have the
fuel tank drained and filled with
the correct fuel before star ting the
engine.
Fuel cut- of f
Your vehicle is equipped with a safety device w hich cuts off the fuel supply in the event of a

Misfuel prevention (Diesel)*
Operation
When a petrol filler nozzle is introduced into the f uel   filler   neck   of   your   Diesel   vehicle,   it   comes  
i

nto   contact   with   the   flap.   The   system   remains  
c

losed   and   prevents   filling.
Do not persist but introduce a Diesel type
filler nozzle. Mechanical   device   which   prevents   filling   the   tank   of   a   Diesel   vehicle   with   petrol.   It   avoids   the   risk   of  
e

ngine   damage   that   can   result   from   filling   with   the   wrong   fuel.
It   remains   possible   to   use   a   fuel   can   to  
f

ill   the   tank.
In   order   to   ensure   a   good   flow   of   fuel,  
d

o   not   place   the   nozzle   of   the   fuel   can  
i

n   direct   contact   with   the   flap   of   the

Travelling abroad
As Diesel fuel pump nozzles may b
e   different   in   other   countries,   the  
p

resence   of   the   misfuel   prevention  
d

evice   may   make   refuelling   impossible.
Before
  travelling   abroad,   we  
r

ecommend   that   you   check   with   the  
C

ITROËN   dealer   network,   whether   your  
v
