battery AUDI S8 2016 Owner's Manual

Driving with your
quattro
With All Wh eel Drive , all four wh eels are driven .
General information
With All W heel Drive, power is dis tribute d to all
four wheels . This happens automatically depend­
ing on your dr iving style and the road conditions
at the time . See also¢
page 190 . With the sport
d ifferent ial*, power d istr ibution to the rear
wheels is variable and can be adjusted with Audi
d rive select*
¢ page 106. Always read and fo llow
safety preca utio ns ¢ ,&. .
Winter tires
When drivi ng in the w inter, you r vehicle with All
Wheel Drive has an advantage, even with reg ular
tires. In winter road cond itions it may be adv isa­
b le to mount w inte r tir es (or a ll-season tires) for
i mproved d riveab ility and bra king : these tires
must be mounted on
all four wheels . See also
¢ page 251, W inter tires.
Snow chains
Where snow chains are mandatory on certain
roads, this normally also a pplies to vehicles w it h
All Whee l Dr ive ¢
page 251, Snow chains.
Replacing wheels /tires
Veh icles w ith All Wheel Drive must always have
tires of the same s ize. A lso avo id tires wi th d iffer­
ent tread depths. For detai ls see page
¢ page 243.
Off-Road driving?
Your Aud i does not have e nough g round clear­
a nce to be used as an off-road vehicle . It is there­
fore best to avoid rough tracks and uneve n ter­
r ain as m uch as possible . Also refe r to
¢page 197.
_& WARNING ,~ -
Always adjust you r driv ing to road and t raffic
conditions . Do not let the extra safety affo rd­
ed by All Wheel Drive tempt you into taking
extra risks.
Sma rt Technology
- Although the A ll Whee l Drive is very effec­
tive, always remember that braking capacity
is limited by t ire tract ion. You shou ld there­
fore not dr ive at excessive speeds on icy or
slippe ry road surfaces .
- On wet road surfaces, be careful not to dr ive
too fast because the front wheels could be­
g in to slide on top of the water (aquap la n­
ing) . If th is should oc cur, you will have no
warn ing from a sudden increase in engine
speed as with a front-wheel d rive vehicle.
Always d rive at speeds which are suited to
the road conditions -risk of c rash.
Energy management
Starting ability is optimized
Energy management controls the distribution of
electrical energy and thus op timizes the availa­
bility of electrical energy for starting the engine .
If a vehicle with a conventional energy system is
not driven for a long pe riod of time, the battery is
discharged by id ling curre nt consumers (e.g. im­
mobilize r) . In certain circumstances i t can resu lt
in t he re being i nsufficien t energy ava ilable to
sta rt the engine.
Intelligent energy manageme nt in you r vehicle
hand les the distribution of electrical energy .
Start ing ability is markedly improved and the life
of the ba ttery is ex tended.
Bas ica lly, energy management cons ists of
bat ­
tery diagnosis , idling current management
and
dynamic energy management .
Battery diagnosis
Battery d iagnosis continuously dete rm ines the
state of the battery. Sensors determine battery
vo ltage, battery current and battery tempera­
tu re. This de termines the current state o f ch arge
and the power of the battery .
Idling current management
Idling current management reduces energy con­
sumption while the vehicle is standing. With the ..,_
195

Smart Technology
ignition switched off, it controls the energy sup­
p ly to the various electrical components. Data
from battery diagnosis is considered.
Depending on the battery's state of charge, indi­
vidual consumers are gradually turned off to pre ­
vent excessive discharge of the battery and thus maintain starting capability.
Dynamic energy management
While the vehicle is being driven, dynamic energy
management distributes the energy generated
according to the needs of the individual compo­
nents.
It regu lates consumption, so that more
electrical energy is not being used than is being
generated and ensures an optimal state of
charge for the battery.
(D Tips
- But even energy management cannot neg­
ate the limits of physics . Cons ider that the
power and life of a battery are limited.
- If starting ability is threatened, the indica­
tor light (•) appears
9 page 15, Cl Battery.
What you should know
The highest priority is given to maintaining start­
ing capability .
The battery is severely taxed in short-distance
driving, in city traffic and during the cold time of
year. Abundant electrical energy is required, but
only a little is generated . It is also crit ica l if the
engine is not running and electrical components
are turned on . In this instance energy is be ing
consumed but none is being generated .
It is in precisely these situations that you will no­
tice energy management actively regulat ing the
d istr ibut ion of energy .
Vehicle stands for an extended period
If you do not driv e your vehicle over a period of
several days or weeks, electrical components are
gradually cut back or switched off. This reduces
energy consumption and ma inta ins starting ca­
pability over a longer period . Some of the con­
ven ience funct ions may not operate, such as the
interior l ights or the power seat adjustment. The
196
convenience functions will be availab le again
when you switch on the ignition and start the en­ gine.
With the engine turned off
If you listen to the radio, for example, with the
engine turned off or use other MMI funct ions,
the battery is being d ischarged .
If starting capab ility is jeopardized due to energy
consumption, a message appears in the MMI dis­
play .
The message indicates that the system will be
switched off automat ically in a moment . If you
wish to cont inue using the functions, you have to
start the engine.
With the engine running
Although electrica l energy is generated when the
vehicle is being driven, the battery can become
discharged. This happens mostly when little en­
ergy is being generated and a great deal con ­
sumed and the battery's state of charge is not
opt imal.
To bring the energy balance back into equilibr i­
um, consumers wh ich require espec ially large
amounts of energy are temporarily cut back or
switched off. Heating systems in particular re­
quire a great dea l of energy. If you notice , fo r ex­
amp le, that the heated seats* or the heated rear
window are not heating, they have been tempo­
rarily cut back or switched off. These systems will
be available aga in as soon as the energy balance
has been restored.
You will also notice that engine idle speed has
been increased slig htly. This is norma l and not a
cause for concern . By increasing engine idle
speed the additional energy required is generat­
ed and the battery is charged.

pollutants in the exha ust gas before they are re ­
leased into the atmosphere.
The exclusive use of unleaded fue l is critica lly im­
portant for the l ife of the catalytic converter and
proper functioning of the engine.
A WARNING
T he temperature of the exha ust system is
high, both when driving and after stopping
the engine.
-
- Never touch the exhaust tail pipes once they
have become hot. This could result in burns.
- Do not park or operate the vehicle in areas
where the hot exha ust system may come in
contact with dry grass, brush, fue l spill or
other mater ial which can cause a fire.
- Do not apply additional undercoating or rustproofing on or near the exhaust mani­
fold, exhaust p ipes, catalytic converter or
heat sh ields. During dr iv ing, the substance
used fo r undercoating could overheat and
ca use a fire.
(D Note
- Be aware that just one tank filling with
le aded fuel will already ser iously degrade
the performance of the catalytic co nverter .
- Do not exceed the correct eng ine oil level
<=;> page 225.
-Do not drive until the fuel tank becomes
complete ly empty. The engine could mis­
fire. Unburned fuel could also get into the
exhaust system and this cou ld cause the
cataly tic converte r to overheat.
- Do not sw itch off the ignition while the veh i­
cle is moving.
- Do not continue to operate your vehicle un­
der these cond it ions, as otherwise fue l can
r each the catalyti c converte r. This cou ld re­
su lt in overheating of the conve rter, req uir­
i ng its replacement.
- T o assure efficient oper ation of the Emis­
s ion Control Sys tem:
- Have your veh icle maintained properly and
in accordance with the service recommen­
dations in your Warranty

-Lack of proper ma intenance as well as im ­
proper use of the vehicle wi ll impair the
funct ion o f the emission control system
and could lead to damage.
@ For the sake of the environment
Even when the Emiss ion Control System is op ­
erating properly, the exhaust gas can have a
su lfu r-li ke exhaust gas sme ll under some op­
erating states. Th is depends on the sulfur
content of the fuel being used. Us ing a d iffer­
ent brand of fuel may help, or fi lling the tank
with lead-free super g rade gasoline.
Diesel particulate filter
App lies to: vehicles with diese l engine
The diesel particulate filter filters nearly all of
the soot part icles out of the exhaus t. The filte r
clea ns itself automat ica lly unde r no rma l dr iv ing
cond it ions. If the fil ter canno t clean i tself (fo r ex­
amp le, because yo u are on ly driving short distan­
ces), the filter becomes clogged with soot and

A WARNING
- Do not park your vehicle over flammable
materials such as grass or leaves because
the high temperature of the diesel particu­
la te filte r could sta rt a fi re.
-
- Do not apply an underbody protectant in the
exhaust system area or a fire could start.
Shutting down vehicle
If you would like your vehicle to remain inopera­
tive for a longer period of time, contact an Audi
or other spec ia lized dealer . They can adv ise you
o n necessary p recautions e .g. corros ion preven­
tion, ma intenance and storage . Pay attention to
additional informat ion concer ning t he battery.
Refer to
<::;> page 2 31.

-Do not remove the engine cover under any
circumstances. This increases the risk of
burns.
- If work on the fuel system or the electrical
system is necessary:
- Always d isconnect the battery.
- Never smoke or work near heaters or open
flames. Flu ids in the engine compartment
could start a fire.
- Keep an app roved fire ext inguisher imme­
d iate ly availab le.
- To avo id electr ical shock and personal injury
wh ile the eng ine 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 repa ir with
the engine running:
- First, fully apply the parking brake, move
selector lever to "P" (Park).
- Always use extreme caution to prevent
cloth ing, jewelry, or long hair from get­
ting caught in the radiator fan, V-belts or
other mov ing parts, or from contacting
hot parts. Tie back ha ir before starti ng,
and do not wear clothi ng that will hang or
d roop into t he engine.

Battery
General information
Under normal operating conditions, the battery
in your Audi does not need any maint enance.
With
high outside temperatures or long daily
drives we recommend tha t you have the electro­
lyte level checked by a service facility. The elec­
trolyte level should also be checked each time
the battery is charged ¢
page 233.
Have the battery checked when you take your ve­
hicle in for serv ice. You are well advised to re­
place a battery that is older than 5 years .
With certain types of airbag deployment, the batte ry is disconnected from the vehicle electri­
cal system for safety reasons¢
& in Repair, care
and disposal of the airbags on page 159 .
Disconnecting the battery terminals
Some vehicle functions (power window regu la­
tors, for example) are lost if the battery te rmi ­
nals are disconnected. These functions have to be
relearned after the battery terminals are con­
nected again. To prevent th is, the battery should
only be disconnected from the vehicle e lectr ica l
system when abso lutely necessary for repairs.
Vehicles not driven for long periods
If you do not drive your vehicle over a period of
several days or weeks, electrical components are
gradually cut back or sw itched off. This reduces
ene rgy consumption and ma inta ins starting ca­
pability over a longer period ¢
page 195. Some
of the convenience functions may not operate,
such as the interior lights or the power seat ad­
justment. The convenience funct ions will be
ava ilable again when you switch on the ignition
and start the engine.
Checking and Filling
Winter operation
During the winter months, battery capacity tends
to decrease as temperatures drop . This is be­
cause more power is also consumed while start­
ing, and the headlights, rear window defogger,
etc., are used more often.
Avo id unnecessary power consumption, particu­
larly in city traffic or when traveling only short
distances . Let your authorized Audi dealer check
the capacity of the vehicle battery before winter
sets in ¢
page 233. A well charged battery will
not only prevent starting problems when the
weather is cold, but will also last longer .
(D Tips
If your vehicle is left standing for several
weeks at extremely low temperatures, the ve­
hicle battery should be removed and stored
where it w ill not freeze . This will prevent it
from be ing damaged and having to be re­
placed.
Working on the battery
Be especially careful when working on or near
the battery.
The battery is located in the luggage compart­
ment under the floor . Before you check anything
in the luggage compartment,
read and heed all

Checking and Filling
A discharged battery can freeze at temperatures
of only 32 F
0 (0 °C). Allow a frozen battery to
thaw completely before attempting to charge it
¢ &. However , we recommend not using a
thawed battery again because the battery casing can be cracked due to ice formation and can leak
battery acid.
Battery charging (Maximum charging rate of
30 amps/14.8 Volt)
When charging at low voltages (e.g . w ith a trick­
le 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 also not nec­
essary to disconnect the cables .
Fast charging the battery (charging rate
above 14.8 Volts)
For technical reasons do not use a battery charg­
er 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 manufactur­
e r when charging your battery.
- Never charge a frozen battery. It may ex­
p lode because of gas trapped in the ice. Al­
low a frozen battery to thaw out first.
- Do not reuse batteries which were frozen.
The battery housing may have cracked and
weakened when the battery froze.
- Charge the battery in a well ventilated area.
Keep away from open flame or electrical
spark. Do not smoke. Hydrogen gas generat­
ed by the battery is explosive.
- To reduce the danger of explosion, never
connect or disconnect charger cables while
the charger is operating.
- Fast charging a battery is dangerous and
should only be attempted by a competent
technician with the proper equipment.
- Battery acid that may spill during charging
should be washed off with a so lution of
233

Check ing and F illing
warm water and baking soda to neutralize
the acid.
CD Note
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
T he new battery must have the same specifica­
t ions and dimensions as the original equipmen t
bat tery.
Int elli g ent en ergy managem ent in your vehicle is
responsible for distributing the electrical energy
throughout your vehicle
r=> page 195. The intelli­
gent energy management system will keep the
engine battery charged better than veh icles w ith­
out this system . To make sure the addit ional
e lectrical energy is avai lab le once again after you
have changed the battery, we recommend that
you install batteries of the same type and manu­ facture on ly (the same as those installed at the
time your vehicle was delivered). Specifications
are listed on the battery housing. Your author­
i z ed dealer must code the battery in the energy
management system to enable you to use the en­
ergy management functions correctly after re ­
placing 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.
CD Note
- Make sure the ventilation hose on the s ide
of the battery is connected, otherw ise
fumes or battery ac id can leak out.
- Vehicles with the Start-Stop-System* are equipped with a special cycle-proof AGM battery . Installing a d ifferent type of bat­
tery can cause problems in the vehicle elec -
234
trical system. When replacing the vehicle
battery, always install one with the same
specifications as the original battery .
- Battery mounts and clamps m ust always be
secured correctly.
- Read and follow the warnings under
¢ page 231, Working on the battery before
performing any work on the battery .
@ For the sake of the environment
Because of the p roblem of proper disposal of
a battery, we recommend your authorized
A udi dealer change the battery for you . Bat­
teries contain sulfur ic acid and lead and must
a lways be disposed of properly in compliance
with all environmental regulations . Disposing
of veh icle batteries improperly is very danger­
ous to the environment .

(D Note
Veh icles with an automatic transmission can­
not be started by pushing or towing.
Starting with jumper
cables
If necessary, the engine can be started by con­
necting it to the battery of another vehicle .
If the engine shou ld fail to start because of a dis ­
charged or weak battery, the battery can be con­
nected to the battery of
another vehicle, using a
pair of jumpe r cables to start the engine.
Jumper cables

frozen battery completely, otherwise it
could explode .
- Do not allow battery acid to contact eyes or
skin. Flush any contacted area with water immediately.
- Improper use of a booster battery to start a
vehicle may cause an exp losion.
- Vehicle batteries generate exp losive gases.
Keep sparks, flame and lighted cigarettes
away from batteries.
- Do not try to jump start any vehicle with a
low acid level in the battery .
- The vo ltage of the booster battery must also
have a 12-Volt rating. The capacity (Ah) of
the booster battery should not be lower
than that of the discharged battery. Use of
batter ies of different voltage or substantial­
ly different "Ah" rating may cause an exp lo­
sion and personal injury .
- Never charge a frozen battery. Gas trapped
