Never  use  a fast  charger  as  a  booster  to  start 
the  engine . This  will serious ly damage  sensi
tive  electronic  components,  such  as  control  units,  relays,  radio,  etc.,  as  well  as  the  battery 
charger. 
Battery  replacement 
The new  battery  must  have  the same  specifica
tions  and  dimensions  as  the  original  equipment 
battery . 
Intelligent  energy  management  in your  vehicle  is 
responsible  for distributing  the  electrical  energy 
throughout  your  vehicle 
¢ page  192 . The intelli 
gent  energy  management  system  w ill keep  the 
engine  battery  charged  better  than  vehicles with
out  this  system . To  make  sure the addit ional 
e lectrica l energy  is  available  once  again after you 
have  changed  the  battery, we recommend  that 
you  install  batteries  of the  same  type  and  manu
facture  only  (the  same  as  those  installed at  the 
time  your  veh icle was  delivered).  Specifications 
are  listed  on  the  battery  housing.  Your author
ized  dealer  must  code  the  battery  in the  energy 
management  system  to  enable  you  to use  the  en
ergy  management  functions  correctly  after  re
p lacing  the battery . 
The  new  battery  must  have  the  same  capacity, 
voltage  (12-volts),  amperage,  construction  and 
plug  sealing . 
When  installing  the  battery,  make  sure  the  igni
tion  and  all  electrical  consumers  are  sw itched 
off. 
(D Note 
Make  sure  the  ventilation  hose on  the  side  of 
the  battery  is connected,  otherw ise  fumes  or 
battery  acid  can  leak  out. 
- Vehicles  with  the  Start-Stop-System*  are 
equipped  with  a  special  cycle-proof  AGM 
battery . Install ing  a  different  type  of bat
tery  can  cause  prob lems  in the  vehicle  elec
trical  system.  When replacing  the  vehicle 
battery,  always  install one with  the  same 
specifications  as  the  original battery. 
Checking  and Filling

Because  of the  problem  of  proper  disposal of 
a  battery,  we  recommend  your  authorized 
Audi dealer  change  the  battery  for you.  Bat

always  be  disposed  of  properly  in compliance 
with  all  environmental  regulations.  Disposing 
of  veh icle  batteries  improperly  is very  danger
