2014 AUDI S6 battery

200 Intelligent technology
critical if the engine is not running and electri­
cal components are turned on. In this in­
stance energy is being consumed but none is
being generated.
It is in precisely these situations that you wi ll
notice energy management actively regulat­
ing the distribut ion of energy .
Vehicle stands for an extended period
If you do not drive your vehicle over a pe riod
of severa l days or weeks, electrical compo­
nents are gradually cut back or switched off.
This reduces energy consumption and main­
tains starting capab ility over a longer period.
Some of the conven ience functions may not
operate, such as the inter ior lights or the
power seat adjustment. The conven ience
functions will be available again when you
switch on the ignition and start the engine.
With the engine turned off
If you listen to the radio, for example, with
the eng ine turned off or use other MMI func­
tions, the battery is being discharged .
If starting capability is jeopardized due to en­
ergy consumption, the following warning ap­
pears in the MMI display:
Please start the engine soon or the system
will be turned off.
The warning indicates that the system will be
turned off automatically after 3 minutes. If
you wish to continue using the functions, you
have to start the engine.
With the engine running
Although elect rical energy is generated when
the vehicle is being driven, the battery can be­
come discharged. This happens most ly when
little energy is being generated and a great
dea l consumed and the battery 's state of
charge is not optimal.
To bring the energy balance back into equili­
brium, consumers which require especia lly
large amounts of energy are temporarily cut
back or switched off. Heating systems in par­
ticular requ ire a great deal of energy. If you notice,
for example, that the heated seats* or
the heated rear window are not heating, they
have been temporarily cut back or switched
off. These systems will be available again as
soon as the energy balance has been restored.
You will also notice that engine id le speed has
been increased slightly. Th is is normal and not
a cause for concern. By increasing engine idle
speed the additional energy required is gener­
ated and the battery is charged.

-Always disconnect the battery.
- Never smoke or work near heaters or open flames. Fluids in the engine com­
partment could start a fire.
- Keep an approved fire extinguisher im­
mediately available.
- To avoid electrical shock and personal in­
jury while the engine is running or being
started, never touch :
- Ignition cables
- Other components of the high voltage
electronic ignition system.
- If you must perform a check or repair
with the engine running:
- First, fully apply the parking brake,
move selector lever to P (Park).
- Always use extreme caution to prevent
clothing, jewelry, or long hair from get­
ting caught in the radiator fan, V-belts
or other moving parts, or from contact­ ing hot parts. Tie back hair before
starting, and do not wear clothing that
will hang or droop into the engine.
- Minimize exposure to emission and
chemical ha zards c:::> & .
A WARNING

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 ives we recommend that you have
the electro lyte level checked by a service fa­
cility . The electrolyte level shou ld also be
checked each time the battery is charged
¢ page 237.
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, core and disposal of the airbags on
page 163.
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, ele ctrical compo­
nen ts are gr adually cut b ack o r swi tched off .
This redu ces energy cons umption and main­
tains starting capab ility over a longer per io d

yo u sw itch on the ign ition an d start the en­
gine.
Winter operation
D ur ing the w inte r mon ths, bat tery ca pa city
tends to decrease as tempera tures drop . This
is beca use more power is a lso consumed wh ile
starting, and the headlights, rear window de­
fogger, etc., are used mo re often.
Avoid unnecess ary powe r consumpt ion, pa r­
ticu lar ly in city traffic o r when traveling only
sho rt distances. Let yo ur authorized A udi
dealer check the capacity of the vehicle bat ­
tery before w inter sets in¢
page 23 7. A well
charged battery will no t on ly prevent star tin g
problems w hen the weather is cold, but w ill
also last longer .
@ Tips
If your vehicle is left standing for seve ral
weeks at extremely low temperatures, the
vehicle battery s hou ld be removed and
stored where it will not freez e. This will
p reve nt it from be ing dam aged and having
to be repl aced .

flame, electric sparks or an open light.
- Do not smoke.
- Do not interchange the positive and neg-
ative cab les.
- When working on the battery, be sure
not to short-circuit the terminals with
tools or other metal objects. This would
cause the battery to heat up very quickly,
wh ich could lead to damage or explosion
and personal injury. -
When a battery is charged, it produces
hydrogen gas which is explosive and
could cause personal injury.
- Always keep the battery well out of the
reach of children.
- Before work is done on the electrical sys­
tem, disconnect the negat ive ground ca­
ble.
- Before performing any work on the e lec­
trica l system, switch off the engine and
ignit ion as well as any electrical equip­
ment. The negative cable on the battery
must be disconnected .
If you are just go­
ing to replace a light bulb, then it is
enough to swi tc h off the lights.
- Before disconnecting the battery, switch
off the anti-theft alarm system! Other­
wise you wi ll set off the alarm.
- When disconnecting the battery, f irst
d isconnect the negat ive cab le and then
the posit ive c ab le.
- Before reconnecting the batte ry, ma ke
sure all e lectr ica l consumers are sw itch­
ed off. Re connect the pos it ive cable first
and then the negative cable. Never inter ­
change the cables - this could start a fire!
- Never charge a frozen or a thawed-out
battery. It could exp lode! If a battery has
frozen, then it must be replaced . A dis­
charged battery can freeze over at 32
°F
(0 oc).
- Make sure the vent hose is always attach­
ed to the opening on the s ide of the bat­
tery.
- Never use batteries which are damaged.
There is the danger of an explosion! Al­
ways rep lace a damaged battery.

using a thawed batte ry again because the bat­
tery casing can be cracked due to ice fo rma­
tion and can leak battery ac id.
Battery charging (Maximum charging rate
of 30 amps/14.8 Volt )
When charging at low vo ltages (e.g. with a
trickle charger) , the battery cables do not
have to be disconnected first . The battery
caps should
not be opened when charging a
battery .
It is not necessary to
remove the battery from
the luggage compartment, and it is a lso not
necessary to disconnect the cab les .

charger that uses voltage greater than 14.8
Volts to charge your vehicle's battery .
_& WARNING
-
Charging a battery can be dangerous.
- Always follow the operating instructions
provided by the battery charger manu­
facturer when charg ing your battery.
- 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.

238 Check ing and filling
- Char ge the bat tery i n a we ll ven tilated
area. Kee p away from open flame or elec­
trical spa rk. Do n ot smoke. Hydrogen gas
generated b y the battery is explosive.
- 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 technicia n w ith the proper equ ip­
ment.
- Battery acid that may spill during charg­ ing should be washed off wit h a solution
of warm water and baking soda to neu­
t rali ze the acid.
(D Note
Never use a fast charger as a booster to
start the engine. This will se riously dam­
age sensitive elect ronic components, such
as control units, relays, rad io, etc., as we ll
as t he battery charger.
Battery replacement
The new battery must have the same specifi­
c ations and dimensions as the original equip­
ment battery.
Intell igent energy management in your veh i­
cle is respons ible for d istributing the e lectr i­
cal energy throughou t your vehicle
qpage 199. The intel ligen t energy manage­
ment system w ill keep the engine battery
charged better than vehicles without th is 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 batteries of the same type and ma nu­
facture only (the same as those installed at
the time your vehicle was delivered). Specifi­
cations a re listed on the battery ho using. Yo ur
author ized de aler must code the b attery in
the energy management system to enable you
to use the energy management fu nctions cor­
rectly after replacing the battery. T
he new battery must have the same capacity,
vo ltage ( 12-volts), amperage, construction
and plug sea ling.
When ins tall ing t he battery, make su re the ig­
nition and a ll elect rical consume rs are switch ­
ed off.
(D Note
M ake sure the ven tilat ion hose on the side
of the ba ttery is connecte d, otherwise
fumes or batte ry acid can lea k out .
- Veh icles with the Start-S top-System * are
equip ped with a spec ial cycle-proof AGM
battery . Install ing a d iffe rent type of
battery can cause problems in the vehi­
cle e lectr ica l system. Whe n replac ing the
vehicle battery, always install one w ith
the same specifications as the origi na l
battery.
@) For the sake of the environment
Because of the prob lem of proper disposal
of a battery, we recomme nd your author­
i zed Audi dealer change the battery fo r
you. Batteri es contain sulfur ic acid and
l ead and must a lways be di spo sed o f prop­
erly in comp liance wi th all envi ronmental
regulations. Disposing of vehi cle batter ies
imprope rly is very dange rous to the envi­
r onment.
