Exhaust tail pipes
Road salt and other corrosive materials will damage the material in
the exhaust tai l pipes if they are not cleaned regularly . Do not clean
the tail pipes with wheel cleaner, paint po lish, chrome polish or other
abras ive cleaners. Clean the ta il pipes w it h ca r care products that are
suitable for sta inless steel.
Your authorized Audi dealer can provide cleaning products that have bee n tested and approved for your veh icle .•
Care of interior
Ap plies to ve hic le s: wit h MMI
MMI display
- Clean the MMI display with a sof t clean cloth and an LCD
cleaner .
The MMI display can be cleaned with a p rofessionally available "LCD
cleaner". The cloth should be slightly dampened with the cleaning
fluid to clean the d isp lay.
0 Note
T o avoid scratching the MMI disp lay, you should never clean it dry .•
Ap plies to ve hicle s: with MMI
MMI control console
- First clean the MMI control console with a brush to
remove dust from the housing.
- Then wipe the MMI control consol e with a clean, soft,
slightly damp cloth.
Safety first
The MMI control console should be cleaned with a brush first so that
no dirt is trapped be tween the bu tto ns and the ho using. We recom­
mend g iv ing the MMI co ntrol console a final w ipe with a cloth moist ­
ened with water and d ish washing detergent .
0 Note
To prevent damage, make sure that no fluid ever gets into the MM I
control console. •
Aluminum trim
Use only neutral-pH products to remove spots and deposits from
aluminum surfaces . Chrome care products and alkaline cleaners wi ll
attack alumi num surfaces and ca n damage them ove r time .
& WARNING
Always read and he ed all WARNIN GS and other information
~page 256. •
Fabrics and fabric coverings
Fabrics and fabr ic coverings (e.g. seats , door tr im panels, etc.) should
be cleaned at regular intervals with a vacuum cleaner . This removes
surface dirt particles which could become embedded in the fabric
through use . Steam cleaners should not be used, because the steam
tends to push the dirt deeper into the fabric and lock it there .
Normal clean ing
Genera lly, we recommend using a soft sponge or a lin t-free
microfiber cloth to the clean fabric . Brushes should only be used for
carpets and floor mats, since other fabric surfaces could be harmed
by brushes . _,,

The intensity of the color determines the visual characteristics and
appea rance. If the s urface of the leather has a typical natu ral look,
then the leather is a nappa leather that has been left in a relatively
natura l condition. This leather offers partic ularly good comfort and
breathes well. Fine veins, closed grains, insect b ites, sk in folds, and
subtle var iations in co lor remain visible. These character istics demon­
st rate that the mater ia l is nat ura l.
Natural nap pa leather is not covered by a color fin ish. It is therefore
mo re sensitive to soiling and we ar, which is some thi ng you need to
consider if children, animals or other factors mig ht prove to be partic­
ularly hard on the leather.
By contrast, leather types that a re cove red by a colo red fi nish layer
are more durab le . This has a positive effect on the leather's resistance
to wear and so ilin g in daily use. On the othe r hand, the typical charac­
teristics of natura l leather are barely or not apparent . However, this
does not mean that the leathe r itse lf is of inferio r quali ty.
Care and handling
Be cause of the exclusive na ture of t he types of leat her t ha t Audi uses
and their unique properties (such as sensitivity to oils, grease, soiling,
e tc. ), yo u will need to be somewhat c arefu l with these leat hers , a nd
a certain type of care is requ ired. For example, dark clothing mate­
r ia ls can dis co lor leather seats (especially if s uch cloth ing is damp and
was not dyed correctly). Dust and dirt particles in pores, folds, and
seams can have an ab rasive effect and can damage the leathe r
surface as well as weaken seams.
T he leather s ho ul d be cleaned regularly as needed . After having been
used for a relatively long time, your leather seats will a cquire a rich
aged f in ish. This is a characterist ic of natura l leather and a s ign of
t rue quality.
In order to maintain the value of this natural product over the life of
yo ur vehicle, you sho uld fo llow the recommendations below :
Safety first
0 Note
• To keep you r leat he r from b leach ing out, do not a llow it to be
exposed to bright s unlight for long periods of time . If yo u have to
leave t he veh icle parked o utside for long pe riods, cover the leather to
protect it from direct exposure to sunlight.
• Sharp objects on clot hing, such as z ippers, rivets or sha rp pieces
on belts can leave permanent scratches or scrape mar ks on the
surfa ce of the leathe r.
(I] Tips
• After ea ch t ime you clean the le athe r and at regular inte rvals, use
a leather preservat ive cream that contains UV-blockers and that
works into the leather . This cream will nourish and moistu rize the
leather, helping it to breathe and stay supp le. It also he lps to build up
a protect ive coa ting on the surface .
• Clean the leather every 2 -3 months, and clean any areas t hat get
so ile d.
• Remove fresh marks made by ballpoint pens, ink, lipstick, shoe
polish, etc. as soon as poss ible.
• Preserve the color of the leather as needed by using a special
c o lored leat he r car e cream to touch up a reas of uneven color. •

Fuel supply
Using the right fuel helps keep the environment clean and
prevents engine damage .
Fuel recommendation
The fuel recommended for your vehicle is unleaded premium grade
g asoline . See also :::>
page 339, "Da ta ". Aud i recommends using TO P
TIER Detergent Gasoline with a minimum octane ra ting of 91 AKI (95
R O N). For more information on TOP TIE R Detergen t Gasoline, please
go to the official website (www. toptiergas .com) .
Th e recommended gasoline octane ratin g for your engine can also be
found on a labe l located on the ins ide of t he fue l fille r flap. This rating
may be specified as AKI o r RON .
Your vehicle may also be ope rated us ing unleaded reg ular gasoline
with a minim um octane rating of 87 AKI/91 RON. However, us ing 87
AKI/91 RON octane fuel will slig htly reduce engine performance.
Use un leaded ga soline only. U nleaded gaso line is available
throughout the USA, Canada, and in most E uropean co untries. We
recommen d that you do not ta ke your veh icle to areas or co unt ries
where unleaded gasoline may not be available.
F or more in formation on re fueling yo ur vehicle, see:::>
page 270 .
Octane rating
Octane r ati ng indi cat es a gaso line's abi lity to resis t engi ne damag ing
"knock" caused by premature ignition and detonat ion. Therefore,
buying the correc t g rade o f gasol ine is very impo rtan t to help preve nt
possible engine damage and a loss of engine performance .
Gaso line most common ly used in the United States and Canada has
the following octa ne rat ings tha t ca n usually be fou nd on the filler
pump :
Safety first
• Premium Grade: 91 - 96 AKI
• Regular Grade: 87 - 90 AKI
E xplanation of t he abb reviations :
AKI= Anti Knock Index= (R +M)/ 2 = (RON+ MON)/2
RO N= Research Octane Number
M ON= M otor Octane Num ber.
0 Note
• Do not use a ny fue l with octane rat ings lower than 87 AKI o r 91
RO N otherwise expens ive engine damage will occ ur.
• Do
not use leaded gasoline. The use of lea ded gasoline w ill
severely damage your veh icle 's cata lytic converter and its abi lity to
cont rol exhaust emissions .•
Blended gasoline
Use of gasoline containing alcohol or MTBE (methyl
tertiary butyl ether)
Yo u may use unleaded gasoline blended w ith alcoho l or MTBE
( c ommon ly referred to as oxygenates) if the blended mix ture meets
the following criteria:
Blend of ga soline methanol (wood alcohol or methyl alcohol)
• Anti -k nock index m ust be 87 AKI or h igher .
• Bl end must con tain no mo re t han 3% methanol.
• Blend must contain more than 2% co-solvents.
Blend of ga soline and ethanol (grain alcohol or ethyl alcohol)
• Anti-knock index must be 87 AKI o r higher.
• Bl end must no t contain more th an 10% ethanol.
Vehicle care Technical data

Fuel supply and filling your fuel tank
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 fo r
winter or summer driving. During seasonal change-over, we suggest
that you fill up at busy gas stat ions where the seasonal adjustment is
more likely to be made in time.
0 Note
• Methano l fuels which do not meet these requirements may cause
corrosion and damage to plastic and rubber components in the fue l
system .
• Do not use fuels that fail to meet the specified criteria in this
chapter .
• If you are unab le to determine whether or not a particu lar fuel
blend meets the spec ifications, ask your serv ice 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 responsi­
bility of Aud i and are not covered under the New Vehicle or the Em is­
sion Control System Warranties.
• If you experience a loss of fuel economy or driveab ility and perfor­
mance problems due to the use of one of these fuel blends, we
recommend that you switch to unblended fuel.•
Gasoline additives
A major concern among many auto manufacturers 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 gaso line g rades contain
substances that can cause deposits to collect on v ital engine parts,
such as fuel injectors and intake valves. A lthough most gasoline
brands include additives to keep eng ine and fuel systems clean, they
are not equally effective.
Audi recommends using TOP TIER Detergent Gasoline. For more
information on TOP TIER Detergent Gasoline, please go to the officia l
webs ite (www.toptiergas.com).
After an extended period of using inadequate fuels, built-up carbon
deposits can rob your engine of peak performance.
0 Note
Damage or malfunction due to poor fuel quality is not covered by the
Audi New Vehicle Limited Warranty. •
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 fail, you can still open the flap
manually- for detailed instructions see~
page 273.
You can find the fue l tank capacity of your vehicle in Technical Data
~page 339.
The label on the inside of the fuel filler flap tells you the correct fuel
for your ve hicle. For more information about fuel specifications, see
~page 269.
Your vehicle fuel tank has an on-board refue lling vapor recovery
system. This feature helps to prevent fuel vapors from escaping from
the tank and polluting the environment wh ile you refuel your veh icle . ..,_

In order to fill the tank properly while protecting the environment,
please follow this refueling procedure carefully.
& 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 containers, 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 blower, etc., be very careful
and always observe local and state laws regarding the use, trans­
portation and storage of such fuel containers. Make certain the
container meets industry standards (ANSI/ASTM F852 -86).
0 Note
Never drive your vehicle until the fuel tank is completely empty . The
irregular supply of fuel can cause misfiring. Gasoline could enter the
exhaust system and damage the catalytic converter. •

Engine oil
Engine oil specifications
The engine oil used in your Audi needs the right kind of oil.
The engine in your Audi is a sophisticated power plant that was built
to exacting specifications. This engine needs the right kind of engine
oil that meets specifications regarding quality and viscosity so that it
can run smoothly and reliably. Choosing the right oil and changing oil
within the time and mileage intervals printed in your vehicle's
Warranty
& Maintenance booklet matters a lot more today than it did
years ago. Audi has developed a special quality standard for engine oil
that will help assure that your vehicle's engine will get the lubrication
it needs for proper operation.
Modern engine lubrication has taken a quantum leap in the last few
years. Many synthetic oils available today provide better engine lubri­
cation that can outlast traditional petroleum-based oils, making
them a smart choice for use throughout the life of your Audi.
Whether you use synthetic or petroleum-based engine oil, the oil that
you use must conform to Audi's oil quality standard VW 502 00 to help keep your vehicle's engine running smoothly and help prevent
the formation of harmful deposits, sometimes called "sludge", that
over time can lead to expensive repairs.
Safety first
At the time of printing, engine oils available in the U.S. and Canada
that meet the exacting specifications of Audi oil standard VW 502 00
are synthetic engine oils. This does not mean, however, that every
synthetic engine oil will meet Audi oil standard VW 502 00. So always
be sure that you use an approved oil.
To help prevent the formation of harmful deposits use only oil with
the following specifications printed on the oil container:
Audi oil standard VW 502 00
Oil container labels may carry the specification singly or in combina­
tion with other designations and oil quality standards.
Viscosity
Engine oils are graded according to their viscosity. The proper
viscosity grade oil for your engine depends on climactic or seasonal conditions where you drive. You can use oil with a viscosity grade of
SAE SW40 across all temperature ranges for normal driving condi­
tions.
However, if engine oil viscosity grade SAE SW40 is not available, you
can also use viscosity grade SAE SW-30 or SAE OW-40 as long as it
meets Audi oil quality standard VW 502 00 specifications.
Because engine oil that meets the Audi oil standard may not be avail­
able everywhere when you need it, we strongly recommend that you
always carry with you an extra quart (liter) of oil that expressly
conforms to the VW 502 00 specification, in case you have to top off
the oil while on the road.
Only if the level of the oil is at or below the minimum mark - and no
oil that expressly conforms to Audi oil standard VW 502 00 specifica­
tions is available -may you top off with a high quality engine oil, pref­
erably synthetic-based, that meets ACEA A3, ACEA AS or ACEA BS or
API SL specifications, but even then, only in viscosity grades SAE SW-
40, SAE SW-30, or SAE OW-40. However, during the entire time
between oil change intervals, never top off with more than a total of
0.5 qt/liter engine oil that does not conform to Audi oil specification
vw 502 00. ..

0 Note
Dr iv ing with an insufficient oil level is likely to cause severe damage
to the engine .
[ i ] 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, preferably 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 authorized Audi
dealer to have the cause of your concern properly diagnosed. Keep in
m ind that the accurate measurement of o il consumption requires
great care and may take some time. An authorized Audi dealer has
instructions about how to measure oil consumption accurately .•
Checking the engine oil level
Fig. 206 MMI Display:
