There   is   a   fault   with   the   engine  l
ubrication   system.You
  must   stop   as   soon   it   is   safe   to   do   so.
Park,   switch   off   the   ignition   and   contact   a   CITROËN  
d

ealer   or   a   qualified   workshop.
Battery charge
fixed. The   battery   charging   circuit   has   a  
f

ault   (dirty   or   loose   terminals,   slack   or  
c

ut   alternator   belt,   ...).
The   warning   lamp   should   go   off   when   the   engine   is  
s

tarted.
If   it   does   not   go   off,   contact   a   CITROËN   dealer   or   a  
q

temperature fixed.
The   temperature   of   the   cooling  
s

Stop   as   soon   as   it   is   safe   to   do   so.
Wait   until   the   engine   has   cooled   down   before   topping  
u

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  
t

he   maximum   permitted   without  
e

xceeding it.
Air density decreases with altitude, thus
reducing
  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.
For
  more   information   on   weights   (and   the  
t

owed loads which apply to your vehicle) refer
to
  the   corresponding   section.
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
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.

Coolant level
The coolant level should be close
to  the   "MA X"   mark   but   should   never  
e

xceed   it.
In
 
addition,   as   the   cooling   system   is   pressurised,
 w

ait
 
at
 
least   one   hour   after   switching   off   the
 e

ngine
 
before   carrying   out   any   work.
To
 
avoid
 
any   risk   of   scalding,   unscrew   the   cap   by
 t

wo
 
turns
 
to   allow   the   pressure   to   drop.   When   the
 p

ressure
 
has   dropped,   remove   the   cap   and   top
 u

p
 
the
 
level.
Changing the coolant
The coolant does not have to be replaced at routine services.
The cooling fan may star t after switching
off the engine: take care with ar ticles and
clothing that might be caught by the fan
blades. When   the   engine   is   warm,   the   temperature   of  
t

he   coolant   is   regulated   by   the   fan.
Fluid specification
The coolant must conform to the ma
nufacturer's r ecommendations.
Fluid specification
For optimum cleaning and to avoid freezing, this   fluid   must   not   be   topped   up   or   replaced  
w

To p p i n g u p
The reservoir must be topped up without delay by   a   CITROËN   dealer   or   a   qualified   workshop.
Diesel fuel additive
level (Diesel with particle
filter)
The additive reservoir low level is
indicated  by   fixed   illumination   of  
A

Most   of   these   fluids   are   harmful   to

Do not discard used oil or fluids into
sewers   or   onto   the   ground.
Take   used   oil   to   a   CITROËN   dealer   or  
a

  qualified   workshop   (France)   or   to   an
