When towing
Distribution of loads
F Distribute the load in the trailer so that the heaviest   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
 e
ngine
 p
erformance.
 A

bove 1 000 metres,   the   maximum   towed  
l

oad   must   be   reduced   by   10 %   for   every  
1 0

00 metres   of   altitude.
Side wind
F Take  into   account   the   increased   sensitivity  t
o   side   wind.
For
  more   information   on   weights   (and   the  
t

owed   loads   which   apply   to   your   vehicle)   refer  
t

o   the   corresponding   section.
F  
I
f   the   warning   lamp   and   the  
S

TOP
 
warning   lamp   come   on,  
s

top the vehicle and switch off
the   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   hadlamp   beam   height  
o

f   your   vehicle.
For
  more   information   on   adjusting   the  
h

eadlamp   beam   height,   refer   to   the  
c

orresponding
 s
ection.
The
  rear   parking   sensors   will   be  
d

eactivated   automatically   if   a   genuine  
C

ITROËN   towbar   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.

It allows the use of the vehicle's electric e
quipment   or   portable   devices   to   be   charged.
Once
  the   state   of   charge   of   the   battery   drops  
t

o   the   reserve   level,   the   system   switches   to

Anti-theft protection
Electronic engine immobiliser
Keep safely, away from your vehicle, the   label   attached   to   the   keys   given   to

a

 
special   code.   When   the   ignition   is   switched  
o

n,
 
this   code   must   be   recognised   for   engine  
s

tarting   to   be   authorised.
This
 
electronic   engine   immobiliser   locks   the  
e

ngine   management   system   a   few   minutes  
a

fter
 
the   ignition   is   switched   off   and   prevents  
s

tarting   of   the   engine   by   anyone   who   does   not
