2013 AUDI A4 SEDAN Owners Manual

(D Note
-To keep your leathe r from bleaching out,
do not a llow it to be exposed to bright
sunlight for long periods of time. If you have to leave the vehicle parked outside
for long periods, cover the leather to protect it from d irect exposure to sun­
l ight .
- Sharp objects on clothing, such as zip­ pers, rivets or sha rp pieces on belts can
l eave pe rmanent scratches o r scrape
mar ks on the surface of the leather.
@ Tips
- After each time you clean the leathe r and
at reg ular i nte rva ls, use a leather prese r­
vat ive cream th at co ntains UV-blo ckers
and th at wor ks into the leather. This
cream will no urish and moistur ize the
l eather, helping it to breathe and stay
supple . It also helps to b uild up a protec­
tive coat ing on the surface.
- Clean the leather every 2 - 3 months,
and clean any areas that get soiled.
- Remove fresh marks made by ba llpoint
pens, in k, lipst ick, shoe polish, etc . as
soon as possib le.
- Preserve the color of the leather as need­
ed by using a special colored leather care
cream to touch up areas of uneven color.

cantara ®.
You may use a suitable shampoo for removing
dust and dirt.
Dust and grit in the pores and seams can
scratch and damage the surface. If the car is
left standing in the sun for long periods, the
Alcantara ® should be protected against direct
sunlight to prevent it from fading . Slight color
variations will develop in normal use and are
not an indication of material deterioration .
IQ) Note
- Never use chemical solvents (e.g . lighter
fluid, turpentine), waxes, shoe polish or
s imilar products on Alcantara ® surfaces .
- To avoid damage, have stubborn stains
removed by a commerc ial cleaning spe­
cialist.
- Do not use brushes, st iff sponges or sim­
i larly abrasive cleaning aids . Safety belts
Only well-maintained safety belts work relia­
bly when needed
.
,. Keep belts clean.
,. For cleaning, use a mild soap and water sol­
ution. Let belts dry thorough ly and away
from d irect sunlight.
,. Do not allow inertia reel safety belts to re­
tract before they are completely dry.
,. Check the condition of your safety be lts
reg­
ularly.
Heavily soiled safety belts may not retract
properly.
A WARNING
-
Damaged safety belts can break in a crash .
- Anyth ing that might damage your safety
be lts could mean that you and your pas­
sengers would not be adequate ly pro­
tected in an accident.
- Safety belt performance depends on cor­
rect installation. Never remove belts
from the vehicle to clean them.
- Do not use chemical cleaning agents,
bleach or dyes. They have corrosive prop­
erties which weaken the webbing.
- When cleaning your safety be lts, inspect
them for damage . If you discover dam­
age, see your authorized Audi dealer.

other information ¢
page 199.
Engine compartment
Be especially careful when cleaning the en­
gine compartment.
Always switch off the ignition before clean­
ing the engine
c.? .&, .
Plenum panel
Remove leaves from the plenum panel in front
of the windshield under the engine hood. This
prevents the water drai n holes from becoming
blocked, and it prevents debris from entering
the vehicle interior through the heating and
ventilat ion ducts .

Corro sion prot ecti on
The engine compa rtment and transmiss ion
have been corrosion-protect ed at the factory.
Good ant i-corrosion treatment is very impor­
tant , particularly in the winter. If the veh icle
is frequent ly driven on sa lt treated roads , the
enti re engine compartment and plenum panel
should be thoroughly cleaned at the end of
wint er and retreated to pr ev ent sa lt damage .
At the same time, the underside of the vehicle
should be washed as we ll.
If the engine compartment is cleaned at any
time with gr ease r emoving solutions
1l, or if
you have the engine washed, the anti-corro­ sion treatment is a lmost always removed as
well. It is therefore essential to have a long­
lasting corrosion protection reapplied to all
surfaces, seams, joints and components in the
e ngine compartment .
.8, WARNING
Be aware: The engine compa rtment of any
motor vehicle is a po ten tially h azardous
area .
- Before working i n the engine compart ­
ment, be s ure to read the in format ion

Fuel recommendation
The fuel recomme nded for you r vehicle is un­
lead ed premium
g rade gasoline . See a lso
¢ pag e 270, Data . Audi recommends usi ng
T OP TIER D eterge nt Gaso line wi th a mini mu m
octa ne ra tin g of 9 1 AKI (95 RON). For more
in fo rmation on TO P TI ER De tergent Gaso line,
p lease go to the officia l webs ite (www.toptier ­
gas.com).
Th e re commended g asoline oct ane r ating for
your engine can a lso be fo und on a label loca t­
e d on the ins ide of the fue l filler flap . This rat ­
ing may be specified as A KI or RO N.
Your veh icle m ay also be oper ated using un­
l ea ded regular g asoline with a min imum o c­
tane rating of 87 AKI/91 R ON. However, using
87 AKI/91 RON octa ne f ue l w ill slightly re ­
d uce eng ine perfo rmance.
Use unleaded gasoline only. Unleaded g aso­
line is availab le th rou gho ut the USA, Canada ,
and in most E uropean countries . We recom­
mend that you do not ta ke yo ur vehicle t o
areas or countries where unleaded gasoline
may not be avai lable.
F or mo re in format io n on refue ling your ve hi­
cle, see
¢ page 212.
Octane rating
Octa ne r ating in dicates a gaso line's abili ty to
res ist engine damaging "knoc k" ca used by
p remature ign ition and detonation. Therefore,
buy ing the correct grade of gaso line is very
important to help prevent possible engine
damage and a loss of engine performance.
Gasoline most commonly used in the Unite d
States a nd Canada has the following octane r
at ings t hat can usu a lly be found on the fi ller
pump:
- Pre mium G ra de: 91 -9 6 A KI
- Regular Grade : 87 -90 AKI
Explanation of the abbreviations:
AKI = Anti K nock Index= (R+M) /2 = (RO N
+ MON)/2
R ON= Resea rch Octane Numb er
MON = Motor Octane Num ber .
(D Note
-Do not use a ny f ue l w it h octane rat ings
lower tha n 87 A KI or 9 1 RO N othe rwise
expensiv e engine damage w ill occur.
- Do
not use leaded gasoline . The use of
lead ed gasoline w ill severely damage
yo ur v ehicl e's catalytic co nve rter a nd its
ability to co ntrol exha ust em ission s.
Blended gasoline
Use of gasoline containing alcohol or
MTBE (methyl tertiary butyl ether)
You may use unleaded g asoline blende d with
alcohol o r MTBE (commonly re ferred to as
oxygenates) if the blende d mixture meets t he
f o llow ing criteria:
Blend of gasoline methanol (wood alcohol or
methyl alcohol)
- Anti -kno ck index mus t be 87 A KI or higher.
- Blend must contain no mor e than 3% me th-
anol.
- Blend must contain more than 2% co-sol-
ve nts .
Blend of gasoline and ethanol (grain alcohol
or ethyl alcohol)
- Anti -knoc k index must be 87 AKI or higher .
- Blend must not conta in mo re than 10%
ethanol.
- Ve hicl es w ith flexible f uel engine: blend
m ust not contain more t han 85% etha no l.
Blend of gasoline and MTBE .,.

-Anti-knock index must be 87 AKI or higher.
- Blend must contain not more than 15%
MTBE.
Seasonally adjusted gasoline
Many gasoline grades are blended to perform
especially well for winter or summer driving. During seasonal change-over, we suggest that
you fill up at busy gas stations where the sea­ sonal adjustment is more likely to be made in
time.
CD Note
- Fuels containing a high percentage of
ethanol such as ESO and E85 may only
be used in vehicles with flexible fuel en­
gines. Using high ethanol fuel in vehicles
not equipped with flexible fuel engines
can cause severe engine damage.
- Methanol fuels which do not meet these
requirements may cause corrosion and
damage to plastic and rubber compo­
nents in the fuel system.
- Do not use fuels that fail to meet the
specified criteria in this chapter.
- If you are unable to determine whether
or not a particular fuel blend meets the
specifications, ask your service station or
its fuel supplier.
- Do not use fuel for which the contents
cannot be identified.
- Fuel system damage and performance
problems resulting from the use of fuels
different from those specified are not
the responsibility of Audi and are not
covered under the New Vehicle or the
Emission Control System Warranties.
- If you experience a loss of fuel economy
or driveability and performance prob­
lems due to the use of one of these fuel
blends, we recommend that you switch
to unblended fuel.
Ethanol fuel (Bio-ethanol)
Applies to vehicles: with flexible fuel engine
Vehicles with flexible fuel engines may be op­
erated with bio-ethanol fuels such as E85
Fuel supply and filling your fuel tank 211
(85% ethanol and 15% gasoline) or with un­
leaded gasoline (91 AKI/ROZ 95). The vehicle
may also be operated with a mixture of these
fuels.
Your fuel consumption will increase when us­
ing bio-ethanol fuels due to the lower amount
of energy contained per unit volume in etha­
nol.
Warming up the Flexible fuel engine in low temperatures
Due to the chemical composition of bio-etha­
nol, a certain amount of fuel ends up in the
engine oil when driving short distances in very
low temperatures . This fuel evaporates again
when the engine is warmed up .
II Please warm up engine.
If the driver message appears in the instru­
ment cluster display, drive with a warm en­
gine to reduce the oil level.
CD Note
- Never fill with methanol or with a higher
percentage of bio-ethanol than 85%
(E85). A higher percentage of bio-etha­
nol in the fuel can cause damage to the
engine or to the fuel system.
- Read and follow the information and tips
about gasoline¢
page 210.
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.
Audi recommends using TOP TIER Detergent
Gasoline. For more information on TOP TIER ..,.

Detergent Gasoline, please go to the official
websit e (www.toptiergas .com) .
After an extended period 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 Ve­
hicle Limited Warranty.
Fuel tank
Fuel filler neck
The fuel filler neck is located on the right rear
side panel behind the fuel fi ller flap.
If the power locking system should fail, you
can st ill open the flap manually -for detailed
instructions see¢
page 214 .
You can find the fuel t ank ca pa city of your ve­
hicle in
Technical Data¢ page 270.
The label on the inside of the fuel filler flap
tells you the correct fuel for your veh icle. For
more inform ation about fuel specifications,
see
¢page 210 .
Your vehicle fuel tank has an on-board refuel­
ling vapor recovery system . This feature helps
to preven t fuel vapors from escaping from the
ta nk and polluting the environment while you
refuel your vehicle . In order to fill the tank
properly while protect ing the env ironment,
p lease follow this refueling procedure careful­
l y .
& WARNING
Under normal operating conditions, never
carry add itiona l fuel containers in your car .
Gas canisters and other containers used to
transport fuel can be dangerous. Such con­
tainers, full or empty, may leak and could
cause a f ire 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 vehicle until the fue l tank
is completely empty. The irregular supply
of fue l can cause misfir ing. Gasoline could
enter the exhaust system and damage the
catalytic converter .

A WARNING
Improper refueling or handling of fuel can
cause fire, explosion and severe burns.
- Fuel is highly flammable and can cause
severe burns and other injuries.
- Failure to shut the engine off while refu ­
eling and/or to insert the pump nozzle
fully into the fuel f iller neck could cause
fuel to spray out of filler neck or to over­
flow. Fuel spray and overflow ing fuel can
cause a fire.
- Never use a cellular telephone wh ile re­
fueling. The electromagnetic radiation
can cause sparks that can ign ite fue l va­
pors and cause a fire.
- Never get back into your vehicle while re­
fueling. If in exceptiona l circumstances
you must get back in your vehicle wh ile
refue ling, make certain that you close
the door and touch me tal to discharge
static electricity before touching the fill­
er nozzle again . Static electricity can
cause sparks that can ignite fuel vapors
released during refueling.
- Never smoke or have an open flame any­
where in or near your vehicle when refu­
eling or filling a portable fuel container.
- For your safety, we strongly recommend
that you do not travel with a portable
fuel container in your vehicle. The con-
Fuel supply and filling your fuel tank 213
tainer, full or empty may leak and could
cause a fire, especially in a crash.
- If, under exceptional circumstances, you
must transport a portable fuel container,
please observe the following:
- Never fill a portable fuel container
while 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 portab le fue l container
on the ground before fi lling .
- Always keep the filler nozzle complete­
l y inside the portab le container befo re
and during filling.
- If filling a portable container made of
metal, the fi ller nozzle must always be
in contact with the container. This will
help prevent static electricity from dis­
charging and cause a fire .
- Never spill fuel inside the vehicle or
luggage compartment . Fuel vapors are
highly flammable .
-Always observe loca l and state/provin­
cial laws regarding the use, storage
and transportation of fuel containers .
- Make certain the fuel container meets
industry standards (ANSI/ ASTM
F852-86) .
(D Note
If any fuel has spi lled onto the car, it
should be removed immediately to prevent
damage to the paint.
@ For the sake of the environment
As soon as the correct ly operated nozzle
switches off automat ically for the first
time, the tank is full. Do not try to add
more fuel because fuel may spill out . In
addition , the expansion space in the fuel
tank w ill be filled -causing the fuel to
overflow when it becomes warm and pol­
l ute the environment. •
