RACING towbar
Your vehicle cannot be fitted with a towbar.   The   space   occupied   by   the  
s

port   diffuser   prevents   this.
Ty r e s
F Check  the   tyre   pressures   of   the   towing  v
ehicle   and   of   the   trailer,   observing   the  
re

commended
 p
ressures.
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.
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.
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.

Checking levels
Check all of these levels regularly, in line with the maintenance and warranty guide. Top them up if necessary, unless other wise indicated.
I f   a   level   drops   significantly,   have   the   corresponding   system   checked   by   a   CITROËN   dealer   or   a   qualified   workshop.
Engine oil level
It is normal to top up the oil level between two   services   (or   oil   changes).   CITROËN  
r

ecommends   that   you   check   the   level,   and   top  
u

p   if   necessary,   every   3   000   miles   (5   000   kms).
The
  check   is   carried   out   either   when  
t

he   ignition   is   switched   on   using   the  
o

il   level   indicator   in   the   instrument  
p

anel for vehicles with an electric oil
level   gauge,   or   using   the   dipstick.
To   ensure   that   the   reading   is   correct,  
y

our   vehicle   must   be   parked   on   a   level  
s

ur face   with   the   engine   having   been   off  
f

or   more   than   30   minutes.
Take   care   when   working   under   the  
b

onnet,   as   certain   areas   of   the   engine  
m

ay   be   extremely   hot   (risk   of   burns)  
a

nd   the   cooling   fan   could   start   at   any  
t

ime   (even   with   the   ignition   off).
Checking using the dipstick
A = MA X
B   =   MIN If
  you   find   that   the   level   is   above   the   A   mark   or  
belo

w the B   mark,   do not star t the engine
.
-  
I
f   the   level   is   above   the   MAX
 
mark   (risk  
o

f   damage   to   the   engine),   contact   a  
C

ITROËN   dealer   or   a   qualified   workshop.
-  
I
f   the   level   is   below   the   MIN
 
mark,   you  
m

ust   top   up   the   engine   oil.
Refer
 
to
 
the
 
"Petrol   engine"   or   "Diesel   engine"  
s

.
Oil grade
Before topping-up the oil or changing the oil, c
heck   that   the   oil   is   the   correct   grade   for   your  
e

ngine   and   conforms   to   the   manufacturer's  
r

ecommendations.

Fluid specification
The brake fluid must conform to the manufacturer's r ecommendations.
The
  brake   fluid   level   should   be   close  
t

o   the   "MA X"   mark.   If   it   is   not,   check

Fluid specification
The coolant must conform to the manufacturer's r ecommendations.
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  
p

ressurised,   wait   at   least   one   hour   after  
s

witching
 
off   the   engine   before   carrying   out   any  
wo

rk.
To

and
 
top   up   the   level.
When
 
the
  engine   is   warm,   the   temperature   of  
t

he
 
coolant   is   regulated   by   the   fan.
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.
