Practical information

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

external   or   on   another   vehicle)   and   jump   leads.
Starting using another
battery
First check that the slave battery has a nominal voltage   of   12   V   and   a   capacity   at   least   equal   to  
t

hat   of   the   discharged   battery.
Do
  not   try   to   start   the   engine   by   connecting   a  
b

attery   charger.
Do
  not   disconnect   the   (+)   terminal   when   the  
e

ngine   is   running.
F
 
C
onnect   the   red   cable   to   the   positive

  functions   are   not   available   if   the  
b

attery   is   not   sufficiently   charged.

229
Protect your eyes and face before handling   the   battery.
All
  operations   on   the   battery   must   be  
c

arried   out   in   a   well   ventilated   area  
a

way   from   naked   flames   and   sources  
o

f   sparks,   so   as   to   avoid   the   risk   of  
e

xplosion   and   fire.

t

hat   the   internal   components   have   not  
b

een   damaged   and   the   casing   is   not

racked,   which   could   cause   a   leak   of  
t

oxic   and   corrosive   acid.
Do
  not   reverse   the   polarity   and   use  
o

nly   a   12   V   charger.
Do
  not   disconnect   the   terminals   while  
t

he   engine   is   running.
Do

a battery charger
Batteries contain harmful substances such a s   sulphuric   acid   and   lead.   They   must   be d

isposed   of   in   accordance   with   regulations
 a

nd   must   not,   in   any   circumstances,   be
 d

iscarded   with   household   waste.
Take
  used   remote   control   batteries   and
 v

ehicle batteries to a special collection
point.
F Follow   the   instructions   for   use   provided   by  t
he   manufacturer   of   the   charger.
Do
  not   disconnect   the   battery   to   charge   it.

Load reduction modeSystem which manages the use of certain functions   according   to   the   level   of   charge  
r

emaining   in   the   battery.
When
  the   vehicle   is   being   driven,   the   load  
r

eduction   function   temporarily   deactivates  
c

ertain   functions,   such   as   the   air   conditioning,  
t

he   heated   rear   screen...
The

harge   in   the   battery.
After
  the   engine   has   stopped,   you   can   still   use   functions   such   as   the   audio   equipment,   windscreen  
w

ipers,   dipped   beam   headlamps,   courtesy   lamps,   etc.   for   a   maximum   combined   period   of  
t

hirty minutes. This
  period   may   be   greatly   reduced   if  
t

he   battery   is   not   fully   charged.
A
  flat   battery   prevents   the   engine   from  
s

tarting.
If
  the   telephone   is   being   used   at   the  
s

ame   time,   it   will   be   interrupted   after  
10
 m

inutes.
Switching to economy mode
Once this period has elapsed, a message appears   in   the   screen   indicating   that   the  
v

ehicle   has   switched   to   economy   mode   and   the  
a

ctive   functions   are   put   on   standby.
Exiting economy mode
These functions are reactivated automatically the   next   time   the   vehicle   is   driven.
F
 
I
n   order   to   resume   the   use   of   these  
f

unctions   immediately,   start   the   engine   and  
l

et   it   run   for   a   few   minutes.
The
  time   available   to   you   will   then   be   double  
t

he   period   for   which   the   engine   is   left   running.  
H

owever,   this   period   will   always   be   between  
f

ive   and   thirty   minutes.

Towing the vehicleProcedure for having your vehicle towed or for towing another vehicle using a removable towing eye.

neral 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:
-

Practical information

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  
t

he   maximum   permitted   without  
e

xceeding 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. Refer
  to   the   "Technical   data"   section   for

etails   of   the   weights   and   towed   loads  
w

hich   apply   to   your   vehicle.
Towing a trailer
Your vehicle is primarily designed for transporting   people   and   luggage,   but   it   may  
a

lso   be   used   for   towing   a   trailer. We
  recommend   the   use   of   genuine  
C

ITROËN   towbars   and   their   harnesses  
t

hat   have   been   tested   and   approved  
f

rom   the   design   stage   of   your   vehicle,  
a

nd   that   the   fitting   of   the   towbar   is  
e

ntrusted   to   a   CITROËN   dealer   or   a  
q

ualified
 w
orkshop.
If   the   towbar   is   not   fitted   by   a  
C

ITROËN   dealer,   it   must   still   be  
f

itted   in   accordance   with   the   vehicle  
m

anufacturer's
 i
nstructions.
Driving   with   a   trailer   places   greater  
d

emands   on   the   towing   vehicle   and   the  
d

river   must   take   particular   care.
driving advice

Towing with the RACIng version
Your vehicle cannot be fitted with a t
owbar.   The   space   occupied   by   the  
s

port   diffuser   prevents   this.
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

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.
The
  rear   parking   sensors   will   be  
d

eactivated   automatically   if   a   genuine
