Cast (light) alloy wheels
Cast (light) alloy wheels require special care .
-Wash the wheels w ith a sponge or hose brush every
other week .
- For deep cleaning after wards, use on ly a dedicated
acid ­
free cast alloy wheel c leaner .
- Rub a co at of
liquid wax onto t he rims every three m onth.
Be sure t o reach and tre at all parts of the rim .
To preserve the decorative appearance of the cas t alloy whee ls,
some special care is necessary . In addition to road dirt and salt,
brake du st is also corr osive. If left on f or to o long, brake dust can

heat sh ields . While d riving , the sub stan ce used for underco ating
c ould overheat and cau se a fire .
• Always read and heed all WARNINGS and other informati on
~ page 230.•
Care of interior
Aluminum trim
Use on ly neutral -pH produc ts to remove spots and deposits from
aluminum surfaces. Chrome care products and alka line cleaners
wi ll attack aluminum surfaces and can damage them over time.
& WARNING
Alway s read and heed all WARNINGS and the infor mation
~ page 2 30. •
Fabrics and fabric coverings
Fabrics and fabric coverings (e .g. seats, door trim pane ls, etc.)
should be cleaned at regu lar intervals with a vacuum cleaner. This
removes surface dirt partic les which could become embedded in
the fabric through use . Steam c leaners s hould not be used , because
the steam tends to push the dirt deeper into the fabric and lock it
t here .
Normal cleanin g
Generally, we recommend using a so ft sponge or a lint -free
microfiber cloth to the clean fabric. Brushes should only be used for carpets and floor mats, since other fabric surfaces could be harmed
b
y brushes .
Normal surface stains can be cleaned using a commercially avai l­
able foam cleaner . Spread the foam on the surface of the fabric with
a soft sponge and work it in gently. Do not satura te the fabric. Then
pat the foam dry using absorbent, d ry cloths (e.g. microfiber cloth)
and vacuu m it after it has dried comp lete ly .
Cleaning stains
Stains caused by beverages (e.g . coffee, fruit juice, etc.) can be
treated with a mild detergent solution. Apply the detergent solution
wi th a sponge . In the case of stubborn stains, a de tergent paste can
be applied direct ly to the stain and worked into the fabric. After ­
wa rds, use copious amounts o f clean wa ter to remove the
remaining detergent . App ly the water with a damp cloth or sponge
and pat the fabric dry with an absorben t, dry c loth.
Stains from choco late or makeup should have detergent paste (e.g.
ox -gall soap) rubbed into them . Afterwards, remove the soap with
water (damp sponge).
A lcoho l can be used to treat stains from grease, oi l, lipstic k or a ba ll­
point pen . Me lted grease or dye must be patted off us ing absorbent
material. It may be necessary to retreat the areas with detergent
paste and wa te r.
I n the case of general so iling of the upholstery and cover material,
we recommend hir ing a specialist that has the equipment to clean
t he seat covers and other fabric sur faces by shampooing and spray
extraction.

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 .,_

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 .
