2013 AUDI S4 fuel type

216 Fuel supply and filling your fuel tank
-Inform your authorized Audi dealer that
you are operating or have operated the
vehicle with E85.
- Read and follow the information and tips
about gasoline
¢ page 214.
@ Tips
I t may take longer to start the engine
when the outside temperature is very cold.
If possible, use winterized fuel if tempera­
tures are below freezing.
Gasoline additives
A major concern among many auto manufac­
turers is carbon deposit build-up caused by
the type of gasoline you use.
Although gasoline grades differ from one manufacturer to another, they have certain
things in common. All gasoline grades contain
substances that can cause depos its to collect
on vital engine parts, such as fuel injectors
and intake valves. Although most gasoline
b rands include additives to keep eng ine and
fuel systems clean, they are not equally effec­
tive.
Aud i recommends using TOP TIER Detergent
Gasoline. For more information on TOP TIER
Detergent Gasoline, please go to the official
website (www.toptiergas .com).
After an extended period of using inadequate
f u els, b uilt-up carbon deposits can rob your
engine of peak performance.
CJ) Note
-Damage or malfunct ion due to poor fuel
quality is not covered by the Audi New
Vehicle Limited Wa rranty.
- Do not add aftermarket fuel addit ive
products to your fuel tank .
Fuel tank
Fuel filler neck
The fuel filler neck is located on the right rear
side panel behind the fuel filler flap. If the power
locking system should fai l, you
can still open the flap manua lly -for detailed
instructions see
¢page 218.
You can find the fuel tank capacity of your ve­
hicle in
Technical Data ¢page 277 .
T he label on the inside of the fuel filler flap
te lls you the correct fuel for your veh icle. For
more information about fuel specifications,
see ¢
page 214.
Your vehicle fuel tank has an on-board refuel­
ling vapor recovery system. This feature helps
to prevent fue l vapors from escaping from the
tank and polluting the environment while you
refuel your vehicle. In order to fi ll the tank
proper ly while protecting the environment,
please fo llow this refueling procedure careful­
ly.
A WARNING "'--
Under normal operating cond itions, never
carry addit ional fuel conta iners in your car .
Gas canisters and other conta iners used to
transport fuel can be dangerous. Such con­
tainers, full or empty, may leak and could
cause a fire in a collision . If you must
transport fuel to use for your lawn mower,
snow b lower, etc., be very careful and al ­
ways observe loca l and state laws regard­
ing the use, transportation and storage of
such fuel containers. Make certain the con­
tai ner meets industry standards (ANSI/
ASTM F852 -86).
(D Note
Never drive your veh icle until the fuel tank
i s completely empty. The irregular supply
of fuel can cause misfiring. Gasoline could
enter the exhaust system and damage the
catalytic converter.

-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 .

Glossary of tire and loading terminology
Accessory weight means the comb ined weight (in excess of
those sta ndard items which may be rep laced)
of au toma tic transmission, power steer ing ,
power brakes, power windows, power seats,
radio, and heater, to the extent that these
items are availab le as factory-installed equip­
ment (whether installed or not) .
Aspect ratio
means the rat io o f the height to the w idth of
the tire in percent . Numbers of 55 or lower in ­
dicate a low sidewall for improved steering re­
sponse and better overa ll handling on dry
pavement .
Bead
means the part of the t ire t hat is made o f
steel wires, wrapped or reinforced by ply cords
and that is shaped to fit the r im.
Bead separation
means a b reakdown of the bond between
components in the bead .
Cord means the strands forming the plies in the
tire.
Tire s an d wheel s 235
typica l in those seasons . Aud i recommends
using winter tires during the winter
months . Low temperatures signif icant ly
dec rease the e lasticity of summer t ires,
which affects tract ion and brak ing ability.
If summer t ires are used i n very co ld tem ­
peratures, cracks ca n form o n the tread
bars , res ulting in perma nen t tire damage
that can cause loud driving noise and un­
bala nced ti re s. Audi i s not respon sible for
th is type of damage .
Cold tire inflation pressure
means the t ire p ress ure recommended by t he
vehicle manufacture r fo r a tire o f a des ignated
s ize t hat has not bee n driven for more than a
coup le o f miles (k ilometers) at low speeds in
the three hour period before the tire press ure
is m easured or adjusted.
Curb weight
me ans the we ight of a motor ve hicle with
st andard equipmen t incl ud ing the max imum
capacity of fuel, oi l, and coolant, air condi ­
tioning and additional weig ht of optiona l
equipment.
Extra load tire
means a t ire design to oper ate a t higher load s
and at higher inflation pressures than the cor­
responding standa rd tire . Extra load tires may
be identified as "XL", "x l", "EXTRA LOAD", o r
"RF" on the sidewal l.
Gross Axle Weight Rating ("GAWR")
me ans the load-ca rry ing capac ity of a single
axle system , measured at the tire -ground in­
te rfaces.
Gross Vehicle Weight Rating ( "GVWR ")
mea ns the maximum total loaded we ight of
the ve hicl e. .,..

Winter tires
Winter tires can improve vehicle handling on
snow and ice . At temperatures below 45 °F
(7 °C) we recommend changing to winter
tires.
In some heavy snow areas, local governments may require true winter or "snow " tires, those
with very deeply cut tread. These t ires shou ld
only be used in pairs and be ins talled on all
four wheels. Make sure you pu rchase snow
tires that are the same size and const ruction
type as the other tires on your vehicle.
Your veh icle is equipped with all whee l drive ,
this wi ll improve tract ion du ring w inter driv­
ing,
even with the standard tires. Howeve r, we
strongly recommend that you a lways equip a ll
four wheels on you r vehicle with correctly fit­
ted winter tires or all -se ason tires, when w in ­
t e r r oad conditions are expected . This also im­
proves the vehicle's braking performance and
reduces stopping distances .
Summe r tires provide less grip on ice and
snow.
Winter tires (snow tires) must always be fitted
on all four wheels.
Ask your autho rized Aud i dea ler or qualified
workshop for permitted
wi nter tir e sizes . Use
only radia l winter tires.
W inte r tir es lose the ir effe ctiveness when the
tread is worn down to a depth of
0.15 7 inch
(4 mm).
Only drive with winter tires unde r winter con­
d itions . Summer tires hand le better when
there is no snow or ice on the roads and the
temperature is
above 45 °F ( 7 °C).
I f you have a flat tire, see notes on spare
wheel
9 page 246.
P lease always remember that w inter t ires may
have a lower speed rating than the t ires origi­
na lly installed on your vehicle at the t ime it
was manufactured. Please see
9 page 247 ,
Speed rating (letter code)
for a List ing of the
speed rating letter codes and the maxim um
speed at which the tires can be driven . The speed rating letter code
(
¢ page 23 7) is
on the side wall of the tire
9 page 246 .
A WARNING ,-
Winter tires have maximum speed lim its
that may be lower than your vehicle's max­
i mum speed. Always know the max imum
speed before dr iv ing off . Never dr ive faster
than the speed permitted for yo ur specific
winter tires. This wi ll cause damage to the
tires leading to an accident and ser ious
personal injury to you and your passen­
gers .
A WARNING ,..___ -
Driving faster than the maximum speed
for which the winter tires on your ve hicle
were designed can cause tire fail ure in­
cluding a blowout and sudden deflation, loss of control, crashes and ser ious per­
sonal injuries. Have worn or damaged tires
replaced immediately .
- W inter tires have maximum speed rating
that may be lower than your vehicle's
maximum speed .
- Never drive faster than the speed for
which the winter or other tires installed on yo ur vehicle are rated .
A WARNING
-Always ad just your dr iv ing to the road and
traffic condit ions . Never let the good ac­
celeration of the winter t ires and al l wheel
drive tempt yo u into ta king ext ra risks. Al­
ways remember:
- When braking, an all wheel drive vehicle
handles in the same way as a front drive
vehicle .
- Drive c arefully a nd reduce your speed on
icy and slippery roads, even w inter t ires
cannot help under black ice conditions .
@ For the sake of the environment
Use summer tires whe n weather condi­
tions permi t. T hey are qu ieter, do not wear
as quickly and reduce fuel consumption .
