Access to the battery
Procedure for starting the engine using another battery or charging a discharged battery.
T he presence of this label, in particular
with
  the   Stop   &   Start   system,   indicates  
t

he   use   of   a   12   V   lead-acid   battery   with  
s

pecial
 t
echnology
 a
nd
 s
pecification;
 t

he   involvement   of   a   CITROËN   dealer  
o

r   a   qualified   workshop   is   essential  
w

hen   replacing   or   disconnecting   the  
b

attery.
After
  refitting   the   battery,   the   Stop & Start
 s

ystem   will   only   be   active   after   a
 c

ontinuous   period   of   immobilisation   of   the
 v

ehicle,   a   period   which   depends   on   the
 c

limatic   conditions   and   the   state   of   charge
 o

f   the   battery   (up   to   about   8   hours). When
  your   vehicle's   battery   is   discharged,   the  
e

ngine   can   be   started   using   a   slave   battery  
(

external   or   on   another   vehicle)   and   jump   lead  
c

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

t   least   equal   to   that   of   the   discharged  
b

attery.
Do
  not   try   to   start   the   engine   by  
c

onnecting   a   battery   charger.
Do
  not   disconnect   the   (+)   terminal   when  
t

he   engine   is   running.
Practical information

286
The batteries contain harmful substances such   as   sulphuric   acid   and   lead.   They m

ust   be   disposed   of   in   accordance
 w

ith   regulations   and   must   not,   in   any
 c

ircumstances,   be   discarded   with   household
 w

aste.
Take
  used   remote   control   batteries   and
 v

ehicle   batteries   to   a   special   collection   point.
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  
a

way   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

void   the   risk   of   explosion.   If   the   battery  
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,  
w

hich   could   cause   a   leak   of   toxic   and  
c

orrosive   acid.
Do
  not   reverse   the   polarity   and   use   only  
a

  12   V   charger.
Do
  not   disconnect   the   terminals   while  
t

he   engine   is   running.
Do
  not   charge   the   batteries   without  
d

isconnecting   the   terminals   first.

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.
