2014 AUDI S4 fuel

@ Tips
It 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 deposits to collect
on vital engine parts, such as fuel injectors
and intake valves. Although most gasoline
brands include additives to keep engine and
fuel systems clean, they are not equally effec­
tive.
Aud i recommends using TOP TIER Detergent
Gasoline. For more information on TOP TIE R
Detergent Gasoline, please go to the officia l
website (www.toptiergas .com) .
Afte r an extended pe riod of using inadequate
fuels, built-up carbon deposits can rob your
engine of peak performance.
CD Note
- Damage or malfunction due to poor fuel
quality is not covered by the Audi New
Vehicle Limited Warranty.
- Do not add aftermarket fuel additive
products to your fuel tank.
Fuel tank
Fuel filler neck
The fuel filler neck is located on the r ight rear
side panel behind the fuel filler flap.
If the power locking system should fail, you
can sti ll open the flap manually - for detailed
instructions see
c:> page 213.
You can find the fue l tank capacity of your ve ­
hicle in

Fuel supply and filling your fuel tank 211
The label on the inside of the fuel fi lier f lap
te lls you the correct fue l for your vehicle. For
more information about fuel specifications,
see
c:> page 209.
Your vehicle fue l tank has an on -board refue l­
ling vapor recovery system. This feature helps
to prevent fuel vapors from escaping from the
tank and polluting the environment while you
refuel your vehicle. In order to fill the tank
proper ly while protecting the environment,
please follow this refueling procedure careful­
ly.
_&. WARNING
Under normal operating conditions, never
carry additional fuel containers in your car.
Gas canisters and other containers used to
transport fuel can be dangerous. Such con­
tainers, fu ll or empty, may leak and could
cause a fire in a collision. If you must
transport fuel to use for your lawn mower,
snow blower, etc., be very careful and al­
ways observe local and state laws regard­
ing the use, transportation and storage of
such fuel containers. Make certain the con­
tainer meets industry standards (ANSI/
ASTM F852 - 86).
CD Note
Never drive your veh icle until the fuel tank
i s completely empty. The irregu la r supply
of fue l can cause misfiring. Gasoline cou ld
enter the exhaust system and damage the
catalytic converter.

completely .
A WARNING
-Im proper refueling or handling of fuel can
cause fire, explosion and severe burns.
- Fuel is highly flammable and can cause
severe burns and other injur ies.
- Failure to shut the engine off while refu­
eling and/or to insert the pump no zzle
fully into the fuel filler neck could cause fuel to spray out of filler neck or to over ­
flow . Fuel spray and overflowing fuel can
cause a fire .
- Never use a cellular telephone while re ­
fueling . The electromagnet ic rad iat io n
can cause sparks that can ignite fuel va­
pors a nd cause a fire .
- Never get back into your vehicle whi le re­
fue ling.
If in exceptional circumstances
you must get back in your vehi cle while
ref ueling, make ce rtain that you close
the door and touch metal to discharge
static electricity before touching the fill ­
er nozzle again . Static e lectricity can
cause sparks that can ignite fuel vapors re leased during refueling .
- Never smoke or have an open flame any­
where in or near your veh icle when refu­
eling or filling a portable fuel conta iner .
- For your safety, we strongly recommend
that you do not travel with a portable
fue l conta iner in your vehicle . The con­
tainer, full or empty may leak and could
cause a fire, especially in a crash .
- If, u nder exceptional c ircumstances, you
must transport a portable fuel conta iner,
p lease observe the following:
- Never f ill a portable f uel container
whi le it is anywhere in or on the vehicle
(for example, in the luggage compart­
ment, or on the trunk). Static electrici­
ty can build up while filling and can ig­
nite fuel vapors causing a fire .
- Always place a portable fue l conta iner
on the ground before fi lling.

-Always keep the f iller nozzle complete­
ly inside the portable conta iner before
and during filling.
- If filling a portable container made of
metal, the filler nozz le must always be
in contact with the container. Th is w ill
he lp prevent static electricity from dis­
charg ing and cause a fire .
- Never sp ill fuel inside the vehicle or
luggage compartment. Fue l vapors are
h ighly f lammable .
- Always observe local and state/provin­ cial laws regarding the use, storage
and tra nspo rta tion of fuel containers.
- Make certa in the fuel container meets
industry standards (A NSI
I ASTM
F852-86).
(D Note
If any fuel has spilled onto the car, it
should be removed immediate ly to prevent
damage to the paint.
@ For the sake of the environment
As soon as the correctly operated nozzle
sw itches off automatically for the fi rs t
time, the tank is full. Do not try to add
more f ue l because fuel may spill out. In
add it ion , the expans io n s pace in the fuel
t ank will be fi lled -ca using the fue l to
overflow when it becomes warm and pol ­
lute the env iro nment.
@ Tips
- Runn ing yo ur engine while re fuelling
may ca use vapors to escape o r even
ca use fue l to spill out of the tank . This
would then shut off the fuel nozzle be­
fo re the tank is fu ll.
- Do not refuel your ve hicle w ith the igni ­
tion t urned on. The fuel gauge may oth­
erwise not ind icate the correct fue l level
after refuel ling.
- The fuel filler flap of your vehicle is not locked when you lock the vehicle from
the i nside.

compartment . Wait until no steam or
coolant can be seen or heard before ca re­
fully opening the hood .
- Keep children away from the engine com ­
partment.
- Never spill flu ids on hot engine compo­
nents. They can cause a fire .
- Never touch the radiator fan. The aux ili­
ary e lectr ic fan is temperature controlled
and can switch on suddenly .
- Never open the coolant reservoir cap
when the eng ine is still warm . The cool­
ant system is pressur ized and hot coo l­
ant could spray out.
- Protect your face, hands and arm from
steam or hot eng ine coolant by placing a
thic k rag over the cap when you open the
coolant reservoir.
- Do not remove the engine cover under
any c ircumstances. Th is increases the
risk of bu rns.
- If wo rk on the fuel system or the electri­
cal sys tem is ne cessary:
- Always disconnect the battery.
- Never smoke or work near heaters or
open flames . Fluids in the engine com­
partment co uld start a fire.
- Keep an approved fire extinguisher im­
mediately ava ilable.
- To avoid electrical s hock and persona l 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 repa ir
with the engine running:
- Fir st, fully apply the parking brake,
move se lector lever of a utomatic trans-

mission to "P" (Park); put manual
transmission in Neutral.
- Always use extreme caution to prevent
clothing, jewe lry, or long hair from get­
ting caught in the radiator fan, V-be lts
or other moving parts, or from contact­ i ng hot parts . Tie back hair before
starting, and do not wear clothing that
will hang o r droop into the engine .
- Minimize exposure to emission and
chemical hazards~&. .

Q) Note
When adding f lu ids, always make sure that
they are poured into the proper conta iner
or f iller opening, otherwise serious dam­
age to vehicle systems w ill occur .
@ For the sake of the environment
To detect leaks in time, inspect the vehicle
floor pan from underneath regular ly . If
you see spots from oil or other veh icle flu­
i ds, have your vehicle inspected by an au­
thorized Audi dealer. •
•

218 Checking and filling
temperatures stay below freezing point for long periods.
Detergent additives in the oil w il l make fresh
oil look dark after the eng ine has been run­
ning for a short time . This is norma l and is not
a reason to change the oi l more often than
recommended.
Damage or malfun ctions due to lack of
maintenance
It is essential that you change your oil at the
recommended intervals using only engine o il
that complies with Audi oi l standard
VW 502 00. Your Limited New Vehicle War­
ranty does not cover damage or malfunctions
due to fail ure to fo llow recommended mainte­
nance and use requ irements as set forth in
the Audi Owner's Manual and Warranty
&
Maintenance booklet . Your dealer will have to
deny warranty coverage unless you present to
the dea ler proof in the form of Service or Re­
pa ir Orders that all scheduled ma intenance
was performed in a timely manner.
Eng ine oil consumption
The engine in your vehicle depends on an ade­
quate amount of oil to lubricate and cool all
of its moving parts.
In order to provide effective lubrication and
cool ing of internal engine components, all in­
ternal combustion eng ines consume a certain
amount of oil. O il consumption varies from
engine to engine and may change significantly
over the life of the engine. Typically, engines
with a specif ied break-in period (see
¢
page 195) consume more oil during the
break-in period than they consume after oil
consumption has stabilized.
Under normal conditions, the rate of oil con­
sumption depends on the quality and viscosity
of the oil, the RPM (revolutions per minute) at
which the engine is operated, the ambient
temperature and road condit ions . Further fac­
tors are the amount of oil d ilution from water
condensat ion or fuel residue and the oxida­
tion level of the oil. As any engine is subject to wear as mi
leage builds up, the oil consump­
tion may increase over time until replacement
of worn components may become necessary.
With all these variab les coming into play, no
standard rate of oil consumption can be es­
tablished or specified. There is no alternative
to regu lar and frequent check ing of the o il lev ­
el, see
Note .
If the yellow engine oil leve l warning symbo l
Ill in the instrument cluster lights up, you
shou ld check the oil leve l as soon as possib le
¢
page 219. Top off the oil at your earliest
convenience ¢
page 219.
A WARNING '"---
Before you check anythi ng in the engine
compartment, always read and heed all
WARNINGS¢
A in Working in the engine
compartment on page 214.
(D Note
Driving w ith an insufficient o il level is like­
ly to cause severe damage to the engine .
(D Tips
-The oil pressure warning display. is
not an indicator of the oil level. Do not
rely on it. Instead, check the oil level in
your engine at regular intervals, pref­ erably each time you refuel, and always
before going on a long trip.
- If you have the impression your engine
consumes excessive amounts of oil, we
recommend that you consult an author­
ized Audi dealer to have the cause of
your concern properly diagnosed. Keep in
m ind that the accurate measurement of
oil consumption requ ires great care and
may take some time. An authorized Aud i
dea ler has instructions about how to
measure oil consumption accurately.
-

-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 .
(D Note
-Please note that summer and winter
tires are designed for the cond itions that
are typ ic al in those seasons. Aud i recom­
mends using w inter t ires du ring the win-
Glossary of tire and loading terminology
Accessory weight
means the comb ined weight (in excess of
those standard items which may be replaced)
of automatic tra nsmission, power steering,
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 ratio of the height to the width of
the tire in percent . Numbers of 55 or lower in­
d icate a low sidewall for improved steering re­
sponse and better overall handling on dry
pavement .
Bead
means the pa rt of the ti re that is made of
steel wires, wrapped or reinforced by ply cords
and that is shaped to fit the rim.
Bead s eparation
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 231
ter months . Low temperatu res signifi­
cantly decrease the elastic ity of summer
t ires, which affects traction and braking
ability. If summer tires are used in very
co ld temperatures, cracks can form on
the tread bars, res ulting in permanent
ti re damage that can cause loud drivi ng
noise and unbalanced tires. Aud i is not
responsib le for this type of damage.
- Burn ished, polished or chromed rims
must not be used in winter weather. Th e
surfa ce of the rims does not have suffi­
c ien t cor rosion pro te cti on for this and
c o ul d be pe rmanen tly damaged by road
salt or similar substances. This damage
is not covered by warranty.
Cold tir e inflation pressure
me ans the t ire press ure re commended by the
vehicle manufacturer fo r a tire o f a des igna ted
size that has not bee n driven for more than a
couple of miles (k ilomete rs) at low speeds in
the three hour pe riod before the tire press ure
is measured or adjusted.
Curb weight
means the weight o f a motor vehicle with
standard equipment including the maximum
capacity of fuel, o il, and coolant, air cond i­
tion ing and additional weight of optiona l
equipment.
E xtra load tire
means a tire design to operate at higher loads
and at higher inflation pressures than the cor­
responding standard tire. Extra load tires may
be identified as "XL", "xl", "EXTRA LOAD", or
"RF" on the sidewall.

- Adjust the tire pressure to the load you are
carrying.
- Reinsta ll the va lve stem cap on the valve .
When should I ch eck the tire pres sur e?
The correct tire pressure is especially impor­
tant at high speeds. The pressure should
therefore be checked at least once a month
and a lways before starting a journey. Do not
forget to check the tire pressure for the spare
wheel.
When should I adj ust the tire p re ss ures?
Adjust the tire pressure to the load you are
carry ing . After changing a wheel
o r replacing
wheels you have to adjust the tire pressures
on all wheels . In addition, you must then initi­
alize the new tire pressures in the tire pres­
sure monitoring system*~
page 249.
A WARNING
Incorrect tire pressures and/or underinf la­
tion can lead sudden tire failure, loss of
control, collision, ser ious personal injury
or even death.
- When the
RI] warning symbol appears in
the instrument cluster, stop and inspect
the tires .
- Incorrect tire pressure and/or underinfla­
t ion can cause increased t ire wear and
can affect the handling of the veh icle and
stopp ing ability.
- Incorrect tire pressures and/or underin­
flation can also lead to sudden tire fa il­
ure, including a blowout and sudden de­
flation, causing loss of vehicle control.
- The driver is responsible for the correct
t ire pressures fo r all tires on the vehicle .
T he applicable p ressure va lues are locat­
ed on a sticker on the driver's side B-pil ­
lar.
- Only when a ll ti res on the vehicle are fi l­
led to the correct pressure, the tire pres­
sure monitoring system* can work cor­
rect ly.
- The use of incorrect tire pressure values
can lead to accidents or other damage.
Therefore it is essential that the driver observe the specified t
ire pressure values
for the tires and the correct pressures for
the function of the ti re pressure monitor­ing system*.
- Always inflate tires to the recommended
and correct t ire pressure before dr iv ing
off.
- Driving with underinflated tires bend
more, letting them get too hot resulting
in tread separation, sudden tire failure
and loss of control.
- Excessive speed and/overloading can
cause heat build-up, sudden tire failure
and loss of cont rol.
- If the tire pressure is too low or too high,
the t ires will wear prematurely and the
veh icle w ill not handle well.
- If the tire is not flat and you do not have
to change a wh eel immediately, drive at
reduced speed to the nearest service sta­
tion to check the t ire p ressure and add
air as required.
Q) Note
D riving without valve stem caps can cause
damage to the tire valves. To prevent this,
a lways make sure tha t factory insta lled
valve stem caps on all whee ls are sec urely
mounted on the valve.
@ For the sake of the environment
U nderinflated tires w ill also incre ase the
fuel consumption .
Tires and vehicle load limits
There are limits to the amount of load or
weight that any veh icle and any tire can carry.
A vehicle that is over loaded will not handle
well and is more d iff icult to stop. Overloading
can not only lead to loss of vehicle control,
but can also damage important parts of the
vehicle and can lead to sudden tire fa ilure, in­
clud ing a b lowout and sudden deflation tha t
can cause the vehicle to crash.
Your safety and that of your passengers also depends on making sure that load limits are .,..

24 6 T ire s and whee ls
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 installed 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. However, 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 si zes . Use
only radia l winter tires.
W inter t ires lose the ir effectiveness 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 242.
Please 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 243,
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 233) is
on the side wall of the tire
9 poge 242.
A WARNING ,-
Winter t ires have maximum speed limits
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 vehicle
were designed can cause tire failure 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 adjust 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 taking ext ra risks. Al­
ways remember:
- When braking, an all wheel drive vehicle
handles in the same way as a front drive
vehicle .
- Drive ca refully and reduce your speed on
icy and slippery roads,
even w inter tires
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 .
