Warning and indicator lamps
When the ignition is switched on
Certain warning lamps come on for a few seconds   when   the   ignition   is   switched   on.
When
  the   engine   is   started,   these   warning  
l

amps   should   go   off.
If
  they   remain   on,   before   moving   off,   refer   to   the  
i

nformation   on   the   warning   lamp   in   question.
Associated warnings
The illumination, fixed or flashing, of certain warning   lamps   may   be   accompanied   by   an  
a

udible   signal   and   the   display   of   a   message.

Screenwash / headlamp
wash fluid level
Specification of the fluid
To ensure optimum cleaning and to avoid freezing,   the   fluid   should   never   be   topped   up   or r

eplaced   by   plain   water.
In wintry conditions, the use of a fluid
with
  an   ethyl   alcohol   or   methanol   base   is  
re

commended.

R

emove
 
the
 
gauge
 
completely
 
from
 
t

he reservoir to read the level in the
transparent
 s

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

xceed   it.
Fluid specification
The coolant must conform to the manufacturer's r ecommendations.
The cooling fan may star t after
switching off the engine: take care
with articles 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.
In   addition,   as   the   cooling   system   is  
p

ressurised, wait at least one hour after
switching   off   the   engine   before   carrying   out  
any   work.
To   avoid   any   risk   of   scalding,   unscrew   the   cap

F If  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   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   vehicle   and   of   the   trailer,   observing  
t

he
 re
commended
 p
ressures.
Lighting
F Check  the   electrical   lighting   and   signalling  o
n   the   trailer.
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   
c
oolant  
t

emperature.
