0 Note
• Never use a power washer to clean the power top itself.
• To avoid damaging your vehicle, always make sure that there is
suff icient distance between the spray head and soft mater ials l ike
rubber hoses, plastic parts and sound -deadening materials. Never
aim the spray head at the same po int for a long time. This also applies
to cleaning headlights and painted bumpers. Remember: the closer
the nozzle is to the surface of the mater ial, the greater the stress on
the material. •
Power top care
The power top requires special care.
Keeping your top looking great and mak ing 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
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 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 br ush
using a convert ible 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 sui tab le for drying the top .
Never use gasoline, spot remover, benzene, paint thinner or solvents
to remove spots. We recommend that you only use cleaners espe­
cially formulated for use on convertib le tops, and that you follow the
produce use directions carefully . Authorized Audi deals can provide
detailed information.

been tested and approved for your vehicle.•
Care of interior
MMI display
- Clean the MMI display with a soft clean cloth and an LCD
cleaner.
The MMI display can be cleaned with a professionally available "LCD
cleaner". The cloth shou ld be slightly dampened with the cleaning
fluid to clean the d isplay.
0 Note
T o avoid scratch ing the MMI display, you should never clean it dry.•
MMI control console
-First clean the MMI control console with a brush to
remove dust from the housing.
- Then wipe the MMI control console with a clean, soft,
slightly damp cloth.
The MM I control console should be cleaned with a brush fi rst so that
no dirt is trapped between the buttons and the housing. We recom­
mend g iv ing the MMI control console a final wipe with a cloth moist­
ened with water and dish washing detergent.
0 Note
To prevent damage, make sure that no fluid ever gets into the MMI
control console. •
Aluminum trim
Use only neutral-pH products to remove spots and deposits from
alumi num surfaces. Chrome care products and alkaline cleaners will
attack aluminum surfaces and can damage them over time .
& WARNING
Always read and heed all WARNINGS and other information
=:>page 260. •
Fabrics and fabric coverings
Fabrics and fabric coverings (e .g . seats, door tr im panels, etc.) should
be cleaned at regular intervals with a vacuum cleaner . This removes
surface dirt particles wh ich could become embedded in the fabric
through use. Steam cleaners should not be used, because the steam
tends to push the d irt deeper into the fabric and lock it there.
Normal cleaning
Generally, we recommend using a soft 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
by brushes.
Normal surface stains can be cleaned using a commercially available
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. m icrofiber cloth) and
vacuum it after it has dr ied completely.
Cleaning stains
Stains caused by beverages (e.g. coffee, fru it juice, etc.) can be
treated with a mild detergent solut ion. Apply the detergent solution
with a sponge. In the case of stubborn stains, a detergent paste can
be applied d irectly to the stain and worked into the fabric. After­
wards, use copious amounts of clean water to remove the remaining _..,
