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  
t

erminal   (+)   of   the   flat   battery   A, then to the
positive
  terminal   (+)   of   the   slave   battery   B.
F
 
C
onnect   one   end   of   the   green   or   black  
c

able   to   the   negative   terminal   (-)   of   the  
s

lave battery B   (or   earth   point   on   the   other  
v

ehicle).

a

llow   it   to   run   for   a   few   minutes.
F
 
O
perate   the   starter   of   the   broken-down  
v

ehicle   and   let   the   engine   run.
 I

m

oments   before   trying   again.
F
 
W
ait   until   the   engine   returns   to   idle,   then  
d

isconnect   the   jump   leads   in   reverse   order.Some
  functions   are   not   available   if   the  
b

attery   is   not   sufficiently   charged.

237
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.
Do
  not   try   to   charge   a   frozen   battery;

t

hat   the   internal   components   have   not  
b

een   damaged   and   the   casing   is   not  
c

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
  not   charge   the   batteries   without  
d

isconnecting   the   terminals   first.
Wash

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
