Cleaning and protection -
----------------
•
• To avoid damaging your vehicle, always make sure that there is
enough d istance between the sprayer and sof t materials like rubber
hoses, plastic parts and sound -deadening materials . Never aim the
sprayer at the same point for a re latively long period of t ime. This
also applies to cleaning headlights and painted bumpers. Remember : the closer the nozzle is to the surface of the material,
the greater the stress on the material. •
Power top care
The power to p requires s pecial c are.
Keeping your top look ing great and making certain that it lasts a
long time depend to a great extent on proper use and care. Remove
bird droppings as soon as possib le, since the corrosive chemicals in
them wi ll cause the rubber impregnation in your top to swell and
possibly allow the fabric to leak.
With normal soiling, all you need to do is c lear the top with a soft
brush and clear water. Always brush in the direction of the fabric
from front to rear.
If the top is very dirty and has spotted areas clean it with a brush
using a convert ib le top cleaner . Always brush in the direction of the
fabric from front to rear . R inse with plenty of clear water, and allow
t he t op to air-dry .
Chamois are not suitab le for drying the top.
Never use gasoline, spot remover, benzene, paint thinner or
solve nts to remove spots . We recommend that you only use
cleaners especia lly formulated for use on convertib le tops , and that
you fol low the produce use d irections carefully. Authorized Audi
dea ls can provide detailed information.

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 .,_
Vehic le care

___ C_ le_ a _ n_i_n ~g _ a_ n_ d __ p_r _o _t _e _c_ t_ i_o _n ___________________________________________ _
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.

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.

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.
