Care of exterior
Washing
Frequent washing protects the vehicle.
Th e best protection against envi ronmental influences is frequent
washing and waxing .
H ow often t his is required depends on:
• H ow much the vehic le is used
• Where the vehicle is pa rked (garage, in the open under t rees,
etc.)
• The seasonal and weather conditions
• Environmental influences
T he longer bird droppings, insects, tree resin, road a nd industrial
grime, tar, soot, road salt and other materials remain on the vehicle

•
High temperatures, as from exposure to intense sunlight, intens ify
the corrosive effect particularly when humidity is high as well.
Under ce rtain circumstances ,
weekly washing may be necessary .
Under other conditions, a monthly washing and waxing may be
adequate.
After the winter, the
underside of the vehicle should be thoroughly
washed preferably in a professional car wash .
& WARNING
Always read and heed all WARNINGS and the information
=>
page 200 . •
Automatic car wash
The vehicle can be washed in almost any modern auto­
matic car wash.
The vehicle paint is so durable that the vehicle can normally be
washed without problems in an automatic car wash . However , the
effect on the paint depends to a large extent on the design of the
facility, the filtering of the wash water, the type of wash and care
material, etc. If the paint has a dull appearance after going through
the car wash or is scratched, bring this to the attention of the oper­
ator immediately . If necessary, use a different car wash .
The power top does not require specia l precautions before passing
through a car wash.
However, the car must not be treated with hot
wax after the wash cycle!
The wax could adversely affect the power
top and even damage the fabric over a period of time.
The power top do es not have to be washed every time you use a car
wash . The power top can be spared if the car wash facility is
equipped with manually adjustable roof brushes or rollers.
Before going through a car wash, be sure to take the usua l precau ­
tions such as closing the windows. Remove antenna if applicable . If
you have installed additional accessories on the vehicle -such as
spoilers, etc. -it is best to ask the car wash operator if these should
be removed.
& WARNING
Always read and heed all WARNINGS and the information
=> page 200. •
Washing the vehicle by hand
A lot of water is needed when washing a vehicle by hand.
-Before you start washing, make sure you have read and
understood the WARNINGS ::}
& in "General informa­
tion" on
page 200.
-First soak all dried dirt until it is soft, then rinse it off.
- As you clean your vehicle, start with the roof and work
your way down to the bottom, using a sponge, a sponge
glove or a clean brush.
- Rinse the sponge or the sponge glove often, flushing it
clean each time.
- Use special car shampoo only for very persistent dirt .
- Rinse the car thoroughly with water.
- Use a chamois leather to gently wipe the exterior dry.
Use a separate sponge for cleaning the wheels, door si lls and other
regions exposed to road dirt. In this way, you will not scratch the
paint with coarse particles imbedded in the sponge the next time
you wash the car . .,,

c£> For the sake of the environment
In the interest of the environment, the vehicle shou ld on ly be
washed in special wash bays. •
Washing your vehicle with a power washer
Cleaning the exterior of your car with a high-pressure
power washer is safe as long as you observe a few simple rules .
-Before us ing the powe r washer, make sure you have read
and understood the WARNINGS~
& in "General infor ­
mation" o n
page 200.
Always follow the operating instructions for the power
washer.
Make sure that the jet o n th e sp ray hose produces a "fan
shaped sp ray".
Do
not hold the spray n ozzle too close to soft ma terials .
Never u se a power washer to clean the power top itself .
When cleaning the vehicle with a power washer
always follow the
operating instructions. This applies particula rly to the
operating
pre ssure
and the spraying di stanc e. Maintain a sufficient distance
to soft materia ls such as rubber hoses and sound/vibration dead­
ening materia ls (particularly on the underside of the engine hood).
Do not use a jet which sprays water in a
di re ct stre am or one that
has a
rotating jet.
Water temperature shou ld not exceed 140 °F (60 °Cl.
in. WARNING
Never wash tires with a jet that sp rays water in a dire ct stream .
Thi s could cause invisib le damage to the tire s and weaken them ,
even if the spra y is fr om a re lative ly lo ng d istanc e and f or a s ho rt
tim e. Damaged and we akened tire s can f ail and cau se ac cident s
a nd pers ona l i njur y. .,,_

0 Note
• Never use a power washer to clean the powe r top itself .
• To avoid damaging your vehicle, always make sure that there is
sufficien t distance between the spray head and soft materials like
rubber hoses, plastic parts and sound -deadening materials. Never
aim the spray head at the same point for a long time. 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. •
Folding top care
The folding top requires special care.
Keeping your top looking 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 possible, since the corrosive chemicals in
them will cause the rubber impregnation in your top to swell and
possibly allow the fabric to leak .
W ith normal soiling, all you need to do is clear 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 convertible top cleaner. Always brush in the direction of the
fabric from front to rear . Rinse with plenty of clear water, and allow
the top to air-dry.
Chamois are not suitable for drying the top.
Never use gasoline, spot remover, benzene, paint thinner or
solvents to remove spots. We recommend that you only use
cleaners especially formulated for use on convertible tops, and that
you follow the produce use directions carefully . Authori zed Audi
deals can provide detailed information.

Waxing
Wax protects the vehicle's paint.
-Use a manually applied car wax occasionally to protect
the paint.
A good wax coating protects the vehicle paint to a large extent
against the environmental factors listed under ~ page 200,
"Washing" and even against slight scratches.
You can use a liquid car wax to protect your paint as soon as one
week after your vehicle has been delivered.
Even if you regularly use a waxing process in automatic car washes ,
we recommend that you manually apply a coat of wax to give the .,_

& WARNING
Alway s read and heed all WARNIN GS and the inform ation

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 particles which could become embedded in
the fabric through use . Steam c leaners should not be used, because
the steam tends to push the dirt deeper into the fabric and lock it
there .
Norm al c leanin g
Generally, we recommend using a so ft sponge or a l int -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 avail­
able foam cleaner . Spread the foam on the surface of the fabric with
a soft sponge and work it in gently. Do not saturate the fabric. Then
pat the foam dry using absorbent, dry cloths (e.g. microfiber c loth)
and vacuum it af ter it has dried complete ly .
C leaning st ains
Stains caused by beverages (e.g . coffee, fruit juice, etc.) can be
treated with a mild detergent solution. Apply the detergent so lution
with a sponge . In the case of stubborn stains, a de tergent paste can
be applied directly to the stain and worked into the fabric. After ­
wa rds, use copious amounts of clean wa ter to remove the
remaining detergent . App ly the water with a damp cloth or sponge
and pat the fabric dry w ith an absorbent, dry c lo th.
Stains from choco late or makeup shou ld have detergent paste (e .g.
ox -gall soap) rubbed into them . Afterwards, remove the soap with
water (damp sponge).
Alcoho l can be used to treat stains from grease, oi l, lipstick or a ba ll­
point pen . Melted grease or dye must be patted off using absorbe nt
material. It may be necessary to retreat the areas with detergent
p aste and wa ter.
I n the case of general soiling of the upholstery and cover material,
we recommend hiring a specialist that has the equipment to clean
the seat covers and other fabr ic surfaces by shampooing and spray
extraction.
