Applies to veh ic les : wi th n atural leat her
Natural leather
Audi makes great effor ts to maintain the proper ties,
n at ural look an d feel of in terior le ather.
General
We offer many different types of leather on our vehic les . Most are
d iff erent types of nappa leather, which has a smoo th surface and
comes in various co lors .
The in tens ity of the c olor de termines the visua l characteristics and
appearance. I f the surface of the leather has a typ ical natu ra l loo k,
then the leather is a nappa leather that has been left in a re latively
natura l condition. This leathe r off ers pa rticu larly good com fort and
breathes we ll. Fine veins, closed grains, insect bites, skin folds, and
su btle varia tions in c olor remain visib le . These characterist ics
demonstrate that the material is natural.
Natura l nappa lea ther is not c ove red by a color finish. It is th erefo re
more sensitive to soiling and wear, which is something you need to
consider if children, animals or other factors might prove to be
particularly hard on the leather .
By contrast, leather types that are covered by a colored finish layer
are m ore dura ble. This has a pos itive effect on the lea ther's resis­
tance to wear and soiling in daily use. On the other hand, the typical
c haracte ristics of natura l leather are barely or not appa re nt.
However , this does not mean that the leather itse lf is of inferior
quality.
Care and handling
Because of the exclusive nature of the types of leat her that Audi
uses and their unique properties (such as sensitivity to oi ls, grease ,
s o iling, etc.), y ou will need to be somewhat ca ref ul w ith t hese
leathers, and a certain type of care is required . For example, dark
c lothing materials can discolor leathe r seats (especially if such
clothing is damp and was not dyed correctly!. Dust and dirt particles .,_

in pores, folds, and seams can have an abrasive effect and can
damage the leather surface as well as weaken seams.
The leather should be cleaned regularly as needed . After having
been used for a relatively long time, your leather seats will acquire
a rich aged finish. This is a characteristic of natural leather and a
sign of true quality.
In order to maintain the value of this natural product over the life of
your vehicle, you should follow the recommendations below :
0 Note
• To keep your leather from bleaching out, do not allow 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 direct exposure to sunlight.
• Sharp objects on clothing, such as zippers, rivets or sharp pieces
on belts can leave permanent scratches or scrape marks on the
surface of the leather .
[ i ] Tip s
• After each time you clean the leather and at regu lar intervals, use
a leather preservative creme that contains UV -blockers and that
works into the leather. This creme will nourish and moisturize the leather, helping it to breathe and stay supple . It also helps to build
up a protective coating on the surface .
• Clean the leather every 2 -3 months, and clean any areas that get
soiled.
• Remove fresh marks made by ballpoint pens, ink, lipstick, shoe
polish, etc . as soon as possible.
• Preserve the color of the leather as needed by using a special
colored leather care creme to touch up areas of uneven color .•
Ap plies to vehi cles: w it h n atu ral leather
Cleaning and caring for leather upholstery
and trim
Natural leather requires special care and attention.
Norm al c leaning
- Clean soiled areas with a slig htly mo istened cotton or
woolen cloth.
Mor e stubborn dirt
- More stubborn dirt can be removed using a cloth satu­
rated with a mild soap solution (2 tablespoons mi ld
liquid soap).
- Never allow the soap solution to saturate the leather, and
make certain that no water soaks into the seams .
Wipe off the soap solution with a soft, dry cloth.
Cl eaning spot s
- Remove fresh wate r-ba sed spots (such as coffee, tea,
juices, blood) w ith an absorbent c loth or paper towe l.
- Remove fresh greas e or oil-ba sed spots (such as butter,
mayonnaise, chocolate) with an absorbent cloth or paper
towel, or use the c leaner from the leather care kit if the
spot has not yet penetrated into the surface of the leather.
- Use an oil/grease dissolving spray, if oil /gr ease spots
h ave dried on .
- Remove specific kinds of spots (ballpoint pen, felt
marker, fingernail polish, water-based paint, shoe polish,
etc.) with a spot remover specifically formulated for leather . .,_

Safety belts
Only well-maintained safety belts work reliably when
needed.
Heavily soiled safety belts may not retract properly.
- Keep belts clean.
- For cleaning, use a mild soap and water solution. Let
belts dry thoroughly and away from direct sunlight.
- Do not allow inertia reel safety belts to retract before
they are completely dry.
- Check the condit ion of your safety belts
regularly.
& WARNING
Damaged safety belts can break in a crash .
• Anything that might damage your safety belts could mean that
you and your passengers would not be adequately protected in an
accident.
• Safety belt performance depends on correct installation. Never
remove belts from the vehicle to clean them.
• Do not use chemical cleaning agents, bleach or dyes. They have
corrosive properties which weaken the webbing.
• When cleaning your safety belts, inspect them for damage. If
you discover damage, see your Audi dealer.
• Always read and heed all WARNINGS and the information
=:> page 230. •
Engine compartment
Be especially careful when cleaning the engine compart­
ment.
Always switch off the ignition before cleaning the engine :::::, &.
Plenum panel
Remove leaves from the plenum panel in front of the windshield
under the engine hood. This prevents the water drain holes from
becoming blocked, and it prevents debris from entering the vehicle
interior through the heating and ventilation ducts.
Corrosion protection
The engine compartment and transmission have been corrosion­
protected at the factory.
Good anti-corrosion treatment is very important, particularly in the
winter. If the vehicle is frequently driven on salt treated roads, the
entire engine compartment and plenum panel should be thor­
oughly cleaned at the end of winter and retreated to prevent salt
damage. At the same time, the underside of the vehicle should be
washed as well.
I f the engine compartment is cleaned at any time with grease
removing solutions
21 , or if you have the engine washed, the anti­
corrosion treatment is almost 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 engine compart ­
ment.
& WARNING
Be aware: The engine compartment of any motor vehicle is a
potentially hazardous area.
• Before working in the engine compartment, be sure to read the
information :::::,
page 242. .,.,
21 Use only the correct cleaning solutions. Never use gasoline or diesel fuel.

& WARNING (continued)
• Before reaching into the front plenum panel, always remove the
ignition key. Otherwise, the windshield wiper system could unin ­
tentionally be switched on, possibly causing personal injury from
the moving wiper linkage.
• Never reach into the area around or touch the radiator fan. The
auxiliary fan is temperature controlled and can switch on suddenly
- even when the ignition is off .
• Do not wash, wax or dry the engine with the engine running .
Moving or hot parts could injure you.
• Do not clean the underside of the chassis, fenders, wheel
covers , or other hard to reach parts without protecting your hands
and arms. You may cut yourself on sharp-edged metal parts .
• Always read and heed all WARNINGS and other information

Gasoline
Fuel supply
Using the right fuel helps keep the environment clean and
prevents engine damage.
Fuel recommendation
Th e fuel recommended for your vehicle is unleaded premium grade
gasoline. See also=>
page 314, "Data". Audi recommends using TOP
TIER Detergent Gasoline with a minimum octane rating of 91 AKI (95
RON). For more information on TOP TIER Detergent Gasoline, please
go to the official website (www .toptiergas.coml.
The recommended gasoline octane rating for your engine can also be found on a label located either on the driver's side B-pillar (visible
when the door is open) or inside the fuel filler flap. This rating may
be specified as AKI or RON.
Your vehicle may also be operated using unleaded regular gasoline
with a minimum octane rating of 87 AKl/91 RON. However, using 87
AKl/91 RON octane fuel will slightly reduce engine performance.
Use unleaded gasoline only. Unleaded gasoline is available
throughout the USA, Canada, and in most European countries. We
recommend that you do not take your vehicle to areas or countries
where unleaded gasoline may not be available.
For more information on refueling your vehicle, see=>
page 245.
Octane rating
Octane rating indicates a gasoline's ability to resist engine
damaging "knock" caused by premature ignition and detonation.
The refore, buying the correct grade of gasoline is very important to
help prevent possible engine damage and a loss of engine perfor ­
mance. Gasoline most commonly used
in the United States and Canada has
the following octane ratings that can usually be found on the filler
pump:
• Pr emium Grade: 91 -96 AKI
• Regular Grade: 87 -90 AKI
Explanation of the abbreviations:
AKI = Anti Kno ck Ind ex= (R+Ml/2 = (RON+MON)/2
RON= Research Octane Number
MON = Motor Octane Number .
0 Note
• Do not use any fuel with octane ratings lower than 87 AKI or 91
RON otherwise expensive engine damage will occur .
• Do
not use leaded gasoline. The use of leaded gasoline will
severely damage your vehicle's catalytic converter and its ability to
control exhaust emissions. •
Blended gasoline
Use of gasoline containing alcohol or MTBE (methyl
tertiary butyl ether)
You may use unleaded gasoline blended with alcohol or MTBE (commonly referred to as oxygenates) if the blended mixture meets
the following criteria:
Blend of gasoline methanol (wood alcohol or methyl alcohol)
• Anti-knock index must be 87 AKI or higher.
• Blend must contain no more than 3% methanol.
• Blend must contain more than 2% co-solvents.

•
Ble nd o f gas oline and eth ano l (gr ain al coh ol o r eth yl a lcoho l)
• Anti -knock index must be 87 AKI or higher.
• Blend must not contain more than 10% ethanol.
Blend of gasoli ne a nd MTBE
• Anti-knock index must be 87 AKI or higher.
• Blend must contain not more than 15% MTBE.
Seasonall y ad ju ste d ga solin e
Many gasoline grades are blended to perform especially well for
winter or summer driving . During seasona l change -over, we suggest
that you fil l up at busy gas stations where the seasonal adjustment
is more likely to be made in time.
0 Note
• Methanol fuels which do not meet these requirements may
cause corrosion and damage to p lastic and rubber components 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 particu lar fuel
blend meets the specifications, ask your service station or its fuel
suppl ier.
• Do not use fuel for which the contents cannot be identified.
• Fuel system damage and performance problems resu lting from
the use of fuels different from those specified are not the responsi ­
bility of Audi and are not covered under the New Vehicle or the
Emission Control System Warran ties.
• If you experience a loss of fue l economy or driveability and
performance problems due to the use of one of these fue l b lends,
we recommend that you switch to unblended fuel.•
Fue l supply and fillin g yo ur fu el tank
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 d iffer from one manufacturer to another,
they have certain things in common. A ll gaso line grades contain
substances that can cause deposits to collect on vita l engine parts,
such as fuel injectors and intake valves. Although most gaso line
brands inc lude additives to keep engine and fue l systems c lean,
they are not equally effective.
Audi recommends using TOP T IER Detergent Gasol ine. For more
information on TOP TIER Detergent Gaso line, please go to the offi­
cial website (www.toptiergas .coml.
After an extended period of using inadequate fue ls, carbon deposit
build -ups can rob your engine of peak performance.
(D Note
Damage or malfunction due to poor fuel qua lity is not covered by
the Audi New Vehic le Limited Warranty .•
