When your vehicle's battery is discharged, the engine   can   be   started   using   a   slave   battery  
(

external   or   on   another   vehicle)   and   jump   lead

ables.
Starting using another
battery
First check that the slave battery has a n ominal   voltage   of   12   V   and   a   capacity  
a

t   least   equal   to   that   of   the   discharged  
b

attery.
Do

Protect your eyes and face before
handling  the   battery.
All
  operations   on   the   battery   must   be  
c

arried out in a well ventilated area and
away
  from   naked   flames   and   sources  
o

f   sparks,   so   as   to   avoid   the   risk   of  
e

xplosion   or   fire.
Do
  not   try   to   charge   a   frozen   battery;  
t

he   battery   must   first   be   thawed   out   to  
a

h

as   been   frozen,   before   charging   have  
i

t   checked   by   a   CITROËN   dealer   or   a  
q

ualified   workshop   who   will   check   that  
t

he   internal   components   have   not   been  
d

amaged   and   the   casing   is   not   cracked,

Towing a trailer
Your vehicle is primarily designed for transporting   people   and   luggage,   but   it   may  
a

lso   be   used   for   towing   a   trailer.
Driving
  with   a   trailer   places   greater   demands  
o

n   the   towing   vehicle   and   the   driver   must   take  
par

ticular
 c
are.Driving advice
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.
ai

r 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.
Side wind
F Take   into   account   the   increased   sensitivity  t
o   side   wind.
Refer to the "Technical data" section for details
of
  the   weights   and   towed   loads   which   apply   to  
y

our   vehicle.
We
 
recommend
 
the
 
use
 
of
 
genuine
 
C

ITR
oËn

towbars and their harnesses
that have been tested and approved
from
 
the
 
design
 
stage
 
of
 
your
 
vehicle,
 
a

nd
 
that
 
the
 
fitting
 
of
 
the
 
towbar
 
is
 
e

ntrusted to a CITR
oËn

dealer or a
qualified
 w

orkshop.
If the towbar is not fitted by a
CITROËN
 
dealer,
 
it
 
must
 
still
 
be
 
f

itted in accordance with the vehicle
manufacturer's
 i

nstructions.

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.
