AUDI S6 2013 Owners Manual

Battery replacement
The new battery must have the same specifi­
cations and dimensions as the original equip­
ment battery.
Intell igent energy management in your vehi­
cle is respons ible for d istributing the electri­
cal energy throughout your vehicle
~ page 197. The intel ligent energy ma nage­
ment system w ill keep the eng ine batte ry
charged be tte r than vehicles w ithout t his sys­
tem . To make sure the additional e lectrical en ­
ergy is available once again after you have
changed the battery, we recommend that you
install batteries of the same type and man u­
facture only (the same as those installed at
the time your vehicle was delivered). Specifi­
cations a re listed on the battery hous ing . Your
author ized dealer must code the battery in
the energy management system to enable you
to use the energy managemen t fu nctions co r­
rectly a fter replacing the battery .
The new battery must have the same capacity,
voltage (12-vo lts), a mperage, construct ion
and p lug sealing.
When installing the battery , make sure the ig ­
n ition and all e lectr ica l cons umers are sw itch­
ed off.
CD Note
Make sure the ventilation hose on the s ide
of the battery is connected, ot herwise
fumes or battery ac id can leak out.
- Vehicles with the Start-Stop-System* are
equipped with a specia l cycle-proof AGM
batte ry. Insta lling a different type of
batte ry can c ause prob lems in the vehi­
cle electrical system . When rep lacing the
vehicle battery, always insta ll one with
the same specifications as the original battery.
@ For the sake of the environment
Because of the problem of proper disposa l
of a battery, we recommend your author­
ized Aud i dea ler change the battery for
you. Batter ies contain sulf uric ac id and

General notes
Tires may be the least appreciated and most
abused parts of a motor vehicle .
Tires may be the least appreciated and most
abused parts of a motor vehicle . Tires are,
however, one of the most important parts of a
vehicle, particularly considering the compara­
tive ly small patch of rubber on each tire that
assures that all -impo rtant contact between
you, your vehicle and the road.
Maintaining the correct tire pressure, mak ing
sure that your vehicle and its tires do not have
to carry mo re weight than they can safe ly han­
d le, avoiding damage from road hazards and
reg ularly inspecting t ires for damage includ­
ing cuts, slashes irregu la r wear and ove rall
condition are the most important things that
you can do to he lp avoid sudden tire failure in­
cluding tread separation and blowouts.
A voidin g damage
I f you have to drive over a curb or similar ob­
stacle, drive very s low ly and as close as possi ­
b le at a right angle to the curb.
A lways keep chem ica ls includ ing grease, o il,
gasoline and b rake fluid off the ti res.
Inspect the t ires regularly for damage (cuts,
cracks or b listers, etc.). Remove any fo reign
bod ies embedded in the treads.
St oring tires
Mark tires when you remove them to indicate
the direction of rotation . Th is ensures you to
be ab le to mount them correctly when you re­
install t hem.
When removed, the wheels or t ires should be
stored in a cool, dry and preferably dark place .
Store tires in a vertical pos ition if they are not
mounted on rims, in a horizontal pos it ion if
they are mounted on rims. New tire
s
New t ires have to be broken in¢&,. .
T he tread depth of new t ires may vary, accord­
ing to the type a nd make of t ire and the tread
pa tte rn .
Hidden damage
Damage to tires and r ims is often not readily
vis ible . If you notice unusual v ibrat ion or the
vehicle p ulls to one side, th is may ind icate
that one of the t ires has been damaged . Th e
t ir es m ust be checked immed iate ly by an au ­
tho rized Aud i dea le r or q uali fied wor kshop.
Unidirectional t ires
A un idirectional tire can be identified by ar­
rows on the sidewa ll, that po int in the direc­
t ion the t ire is designed to rotate. You must
fol low the specified d irection of rotation . This
is necessary so that these tires can develop
their optimum characteristics regarding grip, road no ise, wear and hydrop laning resistance.
For more information ¢
page 268.
A WARNING
-New tires or tires that are old, worn or
damaged cannot provide maximum con­
trol and braking ability .
-
-New tires tend to be slippery and must
be broken in . To reduce the risk of losing
control, a co llision and ser ious personal
in jur ies, d rive w ith special ca re fo r the
fi rst 350 m iles (560 km).
- Driving with worn or damaged tires can
lead to loss of control, sudden tire fail­
ure, including a blowou t and sudden de­
fl ation, c rashes and seriou s personal in­
juries . Have wo rn or damaged t ires re­
p laced immediate ly .
- T ires age even if they are not being used
and can fai l sudden ly, especially at high
speeds. Tires that are more than 6 years
old can only be used in an emergency
and then w ith specia l care and at low
speed.

-Never mount used tires on yo ur vehicle if
yo u are not sure of their "previous histo­
ry." Old used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden tire failure
and loss of vehicle control.
- If you notice unusual vibration or if the
vehicle pulls to one side when d riving, al­
ways stop as soon as it is safe to do so
and check the wheels and tires for dam­
age .

Tire pressure genera lly refers to the amount
of air in a t ire that it needs it to do its job and
safely carry the combined load of the entire
vehicle and its contents . Tire pressure is
measured in kilopasca ls (kPa), the i nterna·
tional measur ing unit and in pou nds pe r
squa re inc h (PSI). Tire pressure is based in
par t on the vehicle's desig n and load limit -
the greatest amoun t of weight that the vehi·
cle can carry safe ly and the t ire size . The prop·
er tire pressure is freq uently referred to as the
" recommended cold tire inf lation pressure."
A ir in the tires expands when the tire heats up
because of internal frict ion when it flexes in
use . The t ire p ressu re is higher when the tire
h as wa rmed up tha n when it is "cold ." It is the
in flat io n pressu re i n a "cold" tire that counts.
Th erefore, you shou ld neve r let air ou t of a
warm tire to match " co ld tire inflat ion pres­
sure" recommendations . The t ires wo uld then
be underinflated and could fail su ddenly .
M ain taining p roper t ire pr essu re is one of the
most im po rt an t th ings you ca n d o to he lp
avoid sudden tire failure. Underin fla ted t ires

i n g tires at the right pressure is also impor­
tant for safe and responsive vehicle handling,

The correct tire pressure for the spare wheel is
located on a label on the driver's side B-pillar.
Because tec hnical changes may be made to
vehicle equ ipment dur ing the model year, a l­
ways compare the tire size designation on the
tire pressure labe l on your vehicle with the
tires on your vehicle . Make sure that the tire
si ze information on the vehicle label is the
same as the si ze of the tires on the vehicle.
This is especially important if the vehicle be ­
longs to someone else or you bought the veh i­
cle with different rims/tires or you bought the
vehicle as a p reviously owned vehicle.
Remember, your safety and that of your pas­
sengers also depends on mak ing sure that
l oad limits are not exceeded. Vehicle load in­
cludes everybody and everything in and on the
ve hicl e. These load limits are technically refer­
red to as the vehicle's Gross Vehicle Weight
Rating ("GVWR") . The Gross Ax le Weight Rat­
ing ("GAWR") is the maximum load that can
be applied at each of the veh icle's two axles.
The Gross Vehicle Weight Rating and the
Gross Axle Weight Rating are listed on the
safety compliance st icker labe l located on the
driver 's side B-p illar . The tire pressure label on
your Aud i lists the maximum combined
weight of all of the occupants and luggage or
o ther cargo that the vehicle can carry. For the
l ocation of the tire pressu re labe l
i=:> fig. 191.
A WARNING
Overloading a vehicle can cause loss of ve ­
hicle control, a cras h or other accident, se­
r ious personal injury, and even death.
- Carrying more weight than yo ur vehicle
was designed to carry will prevent the
vehicle from handling properly and in­
crease the risk of a loss of veh icle con­
trol.
- The brakes on a veh icle that has been
overloaded may not be able to stop the
vehicle within a safe distance.
- Tires on a vehicle that has been overload­
ed can fail suddenly causing loss of con­
trol and a crash . -
Always make sure that the total load be­
ing transported - including the weight of
a trailer hitch and the tongue we ight of a
loaded trailer -does not make the vehi­
cle heavier than the vehicle's G ross Vehi­
cle Weight Rating.
A WARNING
-- I ncorrect tire pressures and/or underin-
flation can lead to a serious or fatal acci­
dent.
- I nco rrect tire pressures and/or underin­
flation cause increased ti re wear and can
affec t the handling of the vehicle .
- I nco rrect tire pressures and/or underin­
flation can a lso lead to s udden t ire fail­
ure, including a blowou t and sudden de­
flation, ca using loss of veh icle cont ro l.
Checking tire pressure
The correct tire pressure for the tires original­
ly installed on your vehicle is listed on the tire
pressur e label located on driver's side 8-pil ­
lar .
The recommended tire pressures are on the
t ir e pressure label and in the table
i=:> page 244, Cold tire inflation pressure.This
means that the pressure m ust be checked and
adjusted when the t ire has not been dr iven for
more than a couple of miles (kilometers) at
low speeds during the previous three hours.
Air in the tires expands when the tire heats up as a result of inter nal frict ion as it flexes in
u se . T he t ire pressure is higher when the tire
has warmed up t han whe n it is "co ld. "
It is the inflation pressure in a "co ld" t ire that
counts . The refore, you should never let a ir out
of a wa rm tire to match "Cold t ire inflat ion
pressure" recomme ndat ions
i=:, page 244 . The
t ir es wo uld then be unde rinflated and co uld
fail suddenly .
T he t ire pressure label on your Audi lists the
recommended co ld tire inflation pressures at
m aximum cap acity for the new, or ig inal
equipmen t tires tha t were on your vehicle at ..,.

the time it was manufactured. For the
l ocation of the labe l¢
fig . 191.
Most ti res lose a ir naturally over time. They
can also lose some a ir if you drive ove r a pot­
hole or hit a curb while parking . It is usua lly
not possib le to see whether the radia l tires
used today are underinflated just by looking
at them.
Therefore, be sure to check tire pressures at
l east once a month and always before going
on a long trip. Make sure to take the number
of people and the amount of luggage into ac­
count when adjusting tire pressure for a trip -
even one that you would not consider to be
"long ." See ¢
page 248, Tires and vehicle
load limits
for more important information .
Always use an accurate tire pressure gauge
when check ing and adjusting inflation pres­
sures . Check all of the t ires and be sure not to
forget the spare t ire. If the p ressure in any tire
i s too high when the tire is "cold," le t air out
of the ti re slowly with t he edge of the t ire
ga uge and keep checking the pressure un til
you reach the press ure that is correct for the
l oad (passengers and luggage) and kind of
driving you plan to do .
I f the p ressure in any tire is too low, note the
d ifference between the pressure in the cold
tire and the pressure yo u need and add the a ir
that you need to reach the correct pressure for
the vehicle load (passengers and luggage) for
the t ires on your vehicle as listed on the on
your veh icle and in this manua l and the kind
of dr iv ing yo u pla n to do .
Never e xceed the ma ximum inflation pres ­
sure listed on the t ire s ide wall for any rea ­
son.
Remember that the vehicle manufacturer, not
the t ire manufacturer, determ ines the correct
tire pressure for the t ires on your vehicle .
It is important to check the tire pressure when
the tires are cold .
- Read the requ ired ti re press ure from the tire
pressure label. The tire pressure labe l is lo­
cated on the driver's side B-pi llar .
Tire s an d wheel s 24 7
- Turn the va lve stem cap counter -clockw ise
to remove it from the tire va lve .
- Place the ai r pressure gauge on the va lve.
- The tire pressures should o nly be checked
a nd ad justed when the tires are co ld. The
slightly raised pressures of warm tires must
not be reduced.
- Adjust the tire pressure to the load you are
carrying.
- Reins tall the valve stem cap on t he va lve.
When should I check the tire pressure?
The correct tire pressure is especially impor­
tant at high speeds . The pressure should
the refore be checked at least once a month

When should I adjust the tire pressures?
Adjust the t ire pr essure to the load you a re
ca rrying. After chang ing a whee l
or replacing
whee ls yo u have to adjust the ti re p ressu res
on all whee ls. In addition, yo u m ust then
store the new tire pressures in the tire pres ­
s u re monito ring system*
q page 258.
A WARNING
Incorrect tire pressures and/or underinfla­
tion can lead sudden tire fa ilure, loss of
control, collision, serious personal injury
or even death.
- When the warning symbol
RI] appears in
the instrument cluster, stop and inspect
the t ires.
- Incorrect tire pressure and/or underinfla­
tion can cause increased tire wear and
can affect the handli ng of the vehicle and
stopping ability.
- Incorrect tire pressures and/or underin­
f lation can a lso lead to sudden t ire fail­
ure, including a blowout a nd sudden de­
f lation, ca u sing loss of veh icle cont ro l.
- T he drive r is responsib le for the co rrect
tire pressures for all tires on the ve hicle.

248 Tire s and whee ls
- Only when all tires on the vehicle are fi l­
led to the correct pressure, the tire pres­
sure monitoring* system can work cor­ rectly.
- The use of incorrect tire pressure values
can lead to accidents or other damage.
Therefore it is essential that the driver observe the specified tire pressure values
for the tires and the correct pressures for
the funct ion of the tire pressure mon itor­
ing system*.
- Always inflate t ires to the recommended
and correct tire pressure before driving
off.
- Driv ing with under inflated ti res bend
more, letting them get too hot resu lting
in tread separation, sudden ti re fail ure
and loss of control.
- Excess ive speed and/overloading can
cause heat bui ld -up, sudden ti re fail ure
and loss of control.
- If the tire press ure is too low or too high,
the tires wi ll wear prematurely and the
vehicle will not hand le we ll.
- If the tire is not flat and you do not have
to change a wheel immediate ly, drive at
reduced speed to the nearest service sta­
t ion to check the tire pressure and add
air as required.
Driving without va lve stem caps can cause
damage to the tire va lves. To prevent this,
always make sure that factory installed
valve stem caps on all wheels are securely mounted on the valve.
@) For the sake of the environment
Underinf lated tires will a lso increase the
fuel consumption.
Tires and vehicle load limits
There are limits to the amount of load or weight that any veh icle and any t ire ca n carry.
A veh icle that is overloaded w ill not handle
well and is more difficult to stop. Over load ing
can not on ly lead to loss of veh icle contro l, but can also damage important parts of the
vehicle and can lead to sudden tire fai lure, in­
clud ing a b lowout and sudden deflation that
can cause the vehicle to crash.
Your safety and that of your passengers also depends on making sure that load limits are
not exceeded. Vehicle load includes everybody
and everything in and on the veh icle. These
load lim its are technically referred to as the
vehicle's
G ro ss Vehicl e We ight R ating
("GVWR").
The "GVWR" includes the weight of the basic
vehicle, all factory installed accessories, a full
tank of fuel, o il, coolant and other fluids plus
maximum load. The max imum load includes
the number of passengers that the vehicle is
intended to car ry ("seat ing capac ity") with an
ass umed we ight of 150 lbs (68 kg) for each
passenge r at a designated seating position
and the total weight of any luggage in the ve ­
hicle . If you tow a trai ler, the weight of the
trailer hitch and the tongue weight of the
loaded tra iler must be included as part of the
vehicle load.
The
G ro ss Axle We ight R ating ("GAWR") is
the maximum load that can be applied at each of the vehicle's two axles.
The Gross Vehicle Weight Rating and the Gross Axle Weight Rating are listed on the
safety comp liance sticker label located on the
driver's side B-pillar . Your Audi has 5 seat ing
pos itions, 2 in the front and 3 in the rear for
total seating capacity of 5 . Each seating posi­
t ion has a safety belt
Q page 136, Safety
belts.
The fact that there is an upper limit to your
vehicle's Gross Vehicle Weight Rating means
that the total weight of whatever is being car­
ried in the vehicle ( includ ing the weight of a
t ra ile r hi tch and the tongue weigh t of the
loaded tra iler) is lim ited. The more passen­
gers in the vehicle or passengers who are
heavier than the standard weights assumed
mean that less weight can be carried as lug-
gage.
