Care of vehicle and cleaning
220Care of vehicle and cleaningGeneral notesRegular care helps to maintain the value of the vehicle.Regular and careful care helps to maintain the value of the vehicle.
This may also be one of the requirements for upholding any
warranty claims in the event of corrosion or paint defects.
Audi dealers and specialist retailers carry stocks of suitable car care
products . Please follow the instructions for use on the packaging.
WARNING
•
Cleaning products and other materials used for car care can
damage health if misused.
•
Car care materials can contain toxic substances and must
always be kept in a safe plac e out of reach of children.For the sake of the environment
•
When purchasing car care products, try to select ones which are
not harmful to the environment.
•
Surplus cleaning materials should not be disposed of together
with ordinary household waste.
Care of exteriorWa s hi ng t he ve hi c l eThe longer substances like insects, bird droppings, resinous tree
sap, road dirt, industrial deposits, tar, soot or road salt and other
aggressive materials remain on the vehicle, the more damage they do to the paintwork. High temper
atures (for instance in strong
sunlight) further intensify the corrosive effect.
After the period when salt is put on the roads it is important to have
the underside of the vehicle washed thoroughly.
Automatic car washes
Before going through a car wash, be sure to take the usual precau-
tions such as closing the windows and sunroof. If the vehicle has
special accessories such as spoilers or a roof carrier or two-way
radio aerial, etc., it is advisable to consult the car wash operator.
It is best to use a car wash without revolving bristles if possible.
Washing your car with a high-pressure cleaner
When cleaning the vehicle with a high-pressure cleaner, always
follow the operating instructions for the equipment. This applies
particularly to the operating pressure and the spraying distance . Do
not hold the spray nozzle too close to soft materials, such as rubber
hoses or seals.
Do not use a nozzle that sp rays the water out in a direct stream or
one that has a rotating jet for forcing off dirt.
Washing the car by hand
When washing the car by hand, use plenty of water to soften the dirt
first, and rinse off as well as possible.
Then clean the vehicle with a soft sponge, glove or brush , using only
slight pressure. You should start on the roof and work down. Special
car shampoo should only be used for very persistent dirt.
Rinse the sponge or glov e thoroughly and often.
Wheels, sills and similar should be cleaned last. Use a second
sponge for this.

Technical data
WARNING
•
Do not wash the vehicle with the ignition switched on – risk of
accident.
•
Do not clean the underside of th e car or inside the wheel arches
without protecting your hands and arms. You may cut yourself on
sharp metal parts.
•
Take care when washing the car during the winter: moisture
and ice on the brakes may affect braking efficiency – this could
cause an accident.Caution
•
Do not wash the vehicle in direct sunlight – otherwise the paint
can be damaged.
•
Do not use insect sponges, or abrasive household sponges, etc.
– they can damage the surfaces.
•
The headlights should only be washed with water – do not wipe
them with a dry cloth or sponge . It is best to use soapy water.
•
Never wash tyres with a jet that sprays the water out in a direct
stream. This could damage the tyres – even if the spray is kept at a
distance and only used for a very short time.For the sake of the environment
The car should only be washed in special wash bays. This prevents
oily water from getting into the pu blic drains. In some districts,
washing vehicles anywhere else may be prohibited.Waxing and polishingWaxing
Waxing protects the paintwork. It is time to apply a good coat of wax
when water no longer forms droplets and rolls off the clean paint-
work. Even if a
wax solution is used regularly in the car wash, it is advis-
able to protect the paint with a coat of wax at least twice a year.
In the summer, you will find it is much easier to remove dead insects
(which accumulate on the bumper an d the front of the bonnet) if the
car has been waxed recently.
Polishing
Polishing is only necessary if the paint has lost its shine, and the
gloss cannot be brought back by putting on wax.
The car must be waxed after polishing if the polish used does not
contain wax compounds to seal the paint.
Caution
Matt painted and plastic parts mu st not be treated with wax or
polish.Ornamental trim and mouldingsThe metal brightwork on the body is made of aluminium rather than
chrome (for environmental reasons).
Dirt or marks on the trim mouldings should be removed with an
acid-free cleaning agent (do not use a chrome cleaner). Body polish
is also unsuitable for use on trim mouldings. The intensive cleaning
fluids often used before the car goes into a car wash may contain
alkaline substances, which can cause dull or milky patches when
they dry out.
Audi dealers carry stocks of cleaning products which have been
tested for use on your vehicle and are not harmful to the
environment.

Care of vehicle and cleaning
222Plastic partsPlastic parts will come clean with regular washing. If this is not suffi-
cient, plastic parts should only be treated with a special solvent-free
plastic cleaning agent . Do not use paint cleaners, polishes or wax on
plastic parts.Paint damageMinor damage to the paint, such as scratches or stone chips, should
be touched up without delay before the metal starts to corrode. Suit-
able touch-up brushes or sprays for your car can be obtained from
an Audi dealer.
The number of the original paint finish on the vehicle is given on the
data sticker ⇒page 293 .
If corrosion is already visible it must be thoroughly removed by a
qualified workshop.Windows
Clear vision is an es sential safety factor.The windscreen must not be cleaned with insect remover or wax,
otherwise the windscreen wipers will not function properly
(juddering).
Traces of rubber, oil, grease or silicone can be removed with a
window cleaning solution or a silicone remover . Wax residue can
only be removed with a special cleaner. Your Audi dealer will be able
to provide you with more detailed information.
The windows should also be cleaned on the inside at regular inter-
vals.
Use a separate cloth or chamois to dry the windows. Cloths used for
waxing and polishing contain residues that will cause smears on the
glass.
WARNING
Do not use water-repellent coatings on the windscreen. In bad visi-
bility conditions such as light rain, low sun or when driving at
night these coatings can cause increased dazzle, which is a
serious safety hazard. Such coat ings can also cause the wiper
blades to judder.
Caution
•
Remove snow and ice from windows and mirrors with a plastic
scraper only. To avoid scratches caused by dirt on the glass, the
scraper should only be pushed in one direction and not moved to
and fro.
•
The heating element for the rear window is located on the inner
side of the window. To avoid damaging the heating element, do not
put stickers on the inner side of the window.
•
Never use warm or hot water to remove snow and ice from
windows and mirrors. This could cause the glass to crack!
Rubber seals (weatherstrips)The weatherstrips will remain pliable and last longer if they are
occasionally treated with a suitable care product (for example sili-
cone spray). This will also preve nt premature ageing and leaks. The
doors will be easier to open as well. If they are kept pliable, the door
seals will be less likely to freeze up in the winter.WheelsThe wheels require regular attention to preserve their appearance.
It is important to remove road salt and brake dust by washing the
wheels at regular intervals, otherwise the finish will be impaired.
