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

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

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

f   sparks,   so   as   to   avoid   the   risk   of  
e

xplosion   and   fire.

racked,   which   could   cause   a   leak   of  
t

oxic   and   corrosive   acid.
Do not reverse the polarity and use
only
  a   12   V   charger.
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 the   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 deactivated functions are reactivated
automatically
  as   soon   as   conditions   permit.Energy economy modeSystem which manages the period of use of certain functions to conserve a sufficient level of c
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

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
five
  and   thirty   minutes.

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:

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.
Air 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. Refer to the "Technical data" section for
details
  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
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 CITROËN 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.
Driving   with   a   trailer   places   greater  
d

emands   on   the   towing   vehicle   and   the  
d

river   must   take   particular   care.
driving advice

231
DS3_en_Chap08_info-pratiques_ed01-2015
Towing with the RACIng version
Your vehicle cannot be fitted with a
towbar.
  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
 
I
f   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  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  
C

ITROËN   towbar   is   used.
