Towing the vehicle
The towing eye is installed in the boot under the   floor.
To
  gain   access   to   it:
F

o
pen the boot,
F
 
l
ift   the   floor   and   remove   it,
F
 
r
emove   the   towing   eye   from   its   housing.
General recommendations
Observe the legislation in force in your country.
E nsure   that   the   weight   of   the   towing   vehicle   is   higher   than   that   of   the   towed   vehicle.
The
  driver   must   remain   at   the   wheel   of   the   towed   vehicle   and   must   have   a   valid   driving   licence.
When
  towing   a   vehicle   with   all   four   wheels   on   the   ground,   always   use   an   approved   towing  
a

rm;   rope   and   straps   are   prohibited.
The
  towing   vehicle   must   move   off   gently.
When
  towing   a   vehicle   with   the   engine   off,   there   is   no   longer   any   power   assistance   for  
b

raking   or   steering.
In
  the   following   cases,   you   must   always   call   on   a   professional   recovery   service:
-
 
v
ehicle   broken   down   on   a   motor way   or   fast   road,
-
 
f
our-wheel   drive   vehicle,
-
 
w
hen   it   is   not   possible   to   put   the   gearbox   into   neutral,   unlock   the   steering,   or   release  
t

he   parking   brake,
-
 
t
owing   with   only   two   wheels   on   the   ground,
-
 
w
here   there   is   no   approved   towing   arm   available...
Procedure

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.
Refer

When

towing
 
a
 
trailer,
 
remove
 
the
 
q

uickly-detachable
 
tow
 
ball
 
before

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
 b

y
 
two
 
turns   to   allow   the   pressure   to   drop.   When
 t

he
 
pressure   has   dropped,   remove   the   cap   and
 t

op
 
up
 
the
  level.
Fluid specification
The coolant must conform to the ma nufacturer's r ecommendations.
The
 
brake
 
fluid
 
level
 
should
 
be
 
close
 
t

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

he
 
brake
 
pad
 
wear.
Brake fluid level
Changing the fluid
Refer to the manufacturer's service schedule f
or   details   of   the   interval   for   this   operation.
Fluid specification
The brake fluid must conform to the manufacturer's r ecommendations. 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.

Checks

318
Brake wear depends on the style of   driving,   particularly   in   the   case  
o

f   vehicles   used   in   town,   over   short  
d

istances.   It   may   be   necessary   to  
h

ave
 
the
 
condition   of   the   brakes   checked,   even  
b

etween
 v
ehicle
 s
ervices.
Unless
 
there   is   a   leak   in   the   circuit,   a   drop   in  
t

he
 
brake
  fluid   level   indicates   that   the   brake  
p

ads
 
are
 
worn.
Brake pads
For information on checking brake d isc   wear,   contact   a   CITROËN   dealer  
o

r   a   qualified   workshop.
Brake disc wear
Only use products recommended by CITROËN   or   products   of   equivalent  
q

uality
 an
d
 sp
ecification.
In
  order   to   optimise   the   operation   of  
u

nits   as   important   as   those   in   the  
b

raking   system,   CITROËN   selects   and  
o

ffers   very   specific   products.
After
  washing   the   vehicle,   dampness,  
o

r   in   wintry   conditions,   ice   can   form  
o

n   the   brake   discs   and   pads:   braking  
e

fficiency   may   be   reduced.   Make   light  
b

rake   applications   to   dry   and   defrost  
t

he   brakes.
Electric parking brake
For more information, refer to the "Electric parking   brake   -   Operating   faults"   section.
This
  system   does   not   require   any  
r

outine   servicing.   However,   in   the  
e

vent   of   a   problem,   have   the   system  
c

hecked   by   a   CITROËN   dealer   or   a  
q

ualified
 w
orkshop.
