2011 AUDI S8 change time

@ For the sake of the environment
Because of the problem of proper disposa l
of brake fl uid as we ll as the special tools
requ ired and the necessary expert ise, we
recommend that you have t he brake fluid
changed by your author ized Audi dealer .
Battery
General information
Under normal operating conditions, the bat­
tery in your Audi does not need any mainte ­
nance. With
high outside temperatures or
long daily dr ive s we recommend that you have
the electro lyte level checked by a service fa­
cility . The electrolyte level shou ld a lso be
checked each time the battery is charged
¢ page 235.
Have the battery checked when you take your
ve hicle in for service . Yo u are well adv ised to
replace a battery that is older than 5 yea rs .
W ith certa in types of a irbag deployment, t he
b attery is d isconnected from the vehicle elec­
tr ica l system for safety reasons¢.&.

pair, care and disposal of the airbags on
page 159.
Disconnecting the battery terminals
Some vehicle functions (power w indow regu­
lators , for example) are lost if the battery ter­
m inals a re d isconnected. These func tions have
to be re lea rned after the batte ry term inals a re
connected agai n. T o prevent this , the bat tery
should only be d isconnec ted from the vehicle
e lec tric al system when absolu tely necessa ry
for repairs .
Vehicles not driven for long periods
If you do not drive you r vehicle over a period
of severa l days or weeks, elec trical compo­
nen ts are gr adually cut b ack o r swi tched off .

tains starting capab ility over a longer per io d

opera te , such as the Conven ience key*, the re­
mote control or the power seat adjustment .
T he convenience functions will be ava ilab le
again when you switch on the ign ition and
start the eng ine.
Winter operat ion
D uring the w inte r mon ths, bat tery capacity
tends to dec rease as temperatures drop . This
is beca use more power is a lso consumed wh ile
starting, and the headlights, rear window de­
fogger, etc., are used more often.
Avoid unnecessary powe r consum ptio n, pa r­
ticu lar ly in city traffic or when traveling only
short distances. Let your autho riz ed Audi
dealer check the capacity of the vehicle bat­
te ry before w inter sets in¢
page 235 . A well
c h arged battery will not on ly prevent s tarti ng
problems w hen the weather is cold, but wi ll
also last longer.
(D Tips
If you r vehicle is left s tandi ng for seve ral
weeks at extremely low temperatures, the
vehicle ba ttery s hould be removed an d
s to red w here i t w ill not fr eeze . T his w ill
p revent it from be in g damaged and having
to be replaced.
Working on the battery
Be especially careful when working on or near
the bat tery.
T he battery is lo cated in the l uggage compa rt­
ment unde r the floo r. B efo re you che ck a ny­

236 Checking and filling
-Never charge a frozen battery. It may ex­
plode because of gas trapped in the ice.
Allow a frozen battery to thaw out first.
- Do not reuse batteries which were fro­
zen. The battery housing may have cracked and weakened when the battery
froze .
- Charge the battery in a well ventilated
area . Keep away from open f lame or elec­
trical spark . Do not smoke. Hydrogen gas
generated by the battery is exp losive.
- To reduce the danger of explosion, never
connect or disconnect charger cables
wh ile the charger is operating.
- Fast charg ing a battery is dangerous and
should only be attempted by a compe­
tent technician with the proper equip­
ment.
- Battery acid that may spill during charg­
ing should be washed
off with a solution
of warm water and bakin g soda to neu­
tralize the acid.
Never use a fast charger as a booster to
start the engine. This will se riously dam­
age sensitive electronic components, such
as control units, relays, radio, etc., as we ll
as the battery charger .
Battery replacement
The new battery must have the same specifi­
cations and dimensions as the original equip­
ment battery.
I ntell igent energy management in your vehi­
cle is respo nsible for distributing the electr i­
cal energy throughout your vehicle
c::> page 195. The intelligent energy manage­
ment system wi ll keep the engine battery
charged better than vehicles without this sys­
tem. To make sure the additional electrical en­
ergy is available once again after you have
changed the battery, we recommend that you install batte ries of the same type and man u­
facture only (the same as those installed at
the time your vehicle was delivered). Specifi- cations are listed on the
battery housing. Your
authorized dealer must code the battery in
the energy management system to enab le you
to use the energy management functions cor­
rectly after replacing the battery.
T he new battery must have the same capacity,
voltage (12 volts), amperage, construction and plug sealing .
When installing the battery, make sure the ig ­
nition and all electrical consumers are switch­
ed off.
(D Note
Make sure the ventilation hose on the side
of the battery is connected, otherwise
fumes or battery acid can leak out .
@ For the sake of the environment
Because of the prob lem of proper disposal
of a battery, we recommend your author­
i zed Audi dealer change the battery for
you. Batteries contain sulfuric acid and
lead and must always be disposed of prop­
erly in compliance with a ll environmental
regulations. Disposing of veh icle batter ies
improperly is very dangerous to the envi­
ronment .
