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.
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 place 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 temperatures (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 sprays 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 glove thoroughly and often.
Wheels, sills and similar should be cleaned last. Use a second
sponge for this.

Do not wash the vehicle with the ignition switched on – risk of
Do not clean the underside of the 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 public 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 and the front of the bonnet) if the
car has been waxed recently.
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.
Matt painted and plastic parts must 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

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 279.
If corrosion is already visible it must be thoroughly removed by a
Clear vision is an essential safety factor.The windscreen must not be cleaned with insect remover or wax,
otherwise the windscreen wipers will not function properly
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-

waxing and polishing contain residues that will cause smears on the
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 coatings can also cause the wiper
blades to judder.
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
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 prevent 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.

Technical data After washing, the wheels should only be cleaned with an "acid-
free" cleaning agent for alloy wheels. This is available from Audi
dealers and specialist retailers. Never leave the cleaning agent on
the rims for any longer than specified in the instructions before
rinsing it off. If the wheel cleaner fluid contains acid it can attack the
surfaces of the wheel bolts.
Car polish or other abrasive agents should not be used. If the
protective paint coating is damaged by stone chips etc., the
damaged area should be touched up immediately.
Please note when cleaning the wheels that water, ice and road salt
can impair the effectiveness of the brakes – this can cause an
accident.Care of interiorMMI display screen and control consoleThe MMI display screen can be cleaned with a soft cloth and a
special “LCD cleaner” (available from retailers of electrical goods).
Moisten the cloth with a small amount of the cleaning fluid.
Clean the MMI control console with a fine brush first to prevent any
dirt from getting in between the control buttons and the housing.
We then recommend wiping the MMI control console using a cloth
moistened with washing-up liquid and water.
To avoid scratching the screen, do not wipe the MMI display with a
To avoid any possibility of damage, do not let any liquid get
inside the control console.
Plastic parts and leatherettePlastic parts and leatherette can be cleaned with a damp cloth. If
this is not sufficient, plastic parts and leatherette should only be
treated with a special solvent-free plastic cleaner.Textile covers and trim partsTextile covers and trim parts (e.g. seats, door trim) should be
cleaned regularly with a vacuum cleaner. This will remove surface
dirt which could otherwise be rubbed into the textile material
during use. Do not use steam cleaners, as the steam could carry the
dirt deeper into the textile material.
We recommend that you use a soft sponge or lint-free, micro-fibre
cloth for normal cleaning. Only use brushes on floor coverings and
mats, as other textile surfaces could become damaged.
In the case of normal surface dirt you can use a foam cleaner. Use a
sponge to spread the foam on the textile surface and to work it into
the material lightly. However, make sure that the textile material
does not become soaking wet. Then dab off the foam with a dry and
absorbent cloth (e.g. a micro-fibre cloth) and vacuum off any
residue once the surface is completely dry.
Removal of stains
To treat stains caused by spilled drinks (coffee, fruit juice or similar)
make up a solution with a mild detergent for sensitive fabrics and
apply it with a sponge. If the stains are difficult to remove, a
washing paste can be applied directly onto the stain and worked
into the fabric. The surface will then have to be wiped with clear
water to remove any residue left by the paste. To do so, use a damp
cloth or sponge and then dab the stain with an absorbent cloth.
Treat chocolate or make-up stains with a washing paste and then
rinse off with water (using a damp sponge).

ball point pen. Then dab the dissolved grease or colour particles off
with an absorbent cloth or similar. You may also have to treat the
stain once more using washing paste and water.
If the covers or textile trim panels are badly soiled we recommend
that you have them cleaned by a professional cleaning company.
Please make sure you close any velcro fasteners on your clothing, as
these could otherwise damage the upholstery.Applies to vehicles: with leather upholsteryNatural leather
Audi does everything possible to preserve the special
qualities of leather as a natural product.General notes
We have a wide selection of leathers. The main type used is nappa
in various forms, that is leather with a smooth surface in a selection
The amount of dye used determines the appearance and properties
of leather. If the leather is left in a more natural state, it retains its
typical natural appearance and is pleasant and comfortable for the
seat occupants. Fine veins, healed scars, insect bites, wrinkles and
a subtle variation in shading remain visible; these are the character-
istic features of genuine natural leather.
Natural napped leather does not have a protective surface coating
of dye. It is therefore somewhat more prone to damage. You should
bear this in mind if children or pets often travel in the car, or if there
are other factors that could lead to damage.
Types of leather with a coloured surface coating are likely to be
more resistant to damage. This has a great advantage for day-to-day use. However, this means that the typical natural characteristics of
the surface are less apparent, though this does not affect quality.
Cleaning and care
Because of the natural properties of the specially selected hides
employed, the finished leather has a certain sensitivity to grease
and dirt, etc. so a degree of care is required in everyday use and
when looking after the leather. Dark clothing (especially if damp or
incorrectly dyed) may stain leather upholstery. Dust and grit in the
pores and seams can have an abrasive effect and damage the
surface of the leather. Therefore leather should be cleaned at
regular intervals, depending on the actual amount of use. When
they have been in use for a certain time, your car seats will acquire
a typical and distinctive patina. This is characteristic for real leather
upholstery, and is a sign of genuine quality.
To maintain the value of natural leather you should note the
Avoid exposing leather to direct sunlight for long periods, other-
wise it may tend to lose some of its colour. If the car is left for a
prolonged period in the bright sun, it is best to cover the leather.
Sharp-edged objects on clothing, such as belts, zip fasteners,
rivets or similar, can also leave permanent scratches and rough
marks on the surface of the leather.Note
Use a suitable impregnating cream with ultra-violet protection at
regular intervals and after cleaning. This cream will nourish and
moisturise the leather, keep it supple and able to breathe. In addi-
tion, it will also help to protect the surface of the leather.
Clean the leather every 2 to 3 months and remove fresh dirt as

Remove stains from fresh ball-pen and other inks, lipstick, shoe
cream and similar stains as soon as possible.
Preserve the colour of the leather. A special coloured cream will
renew the colour of the leather when required and will eliminate
differences in colour.
Applies to vehicles: with leather upholsteryCleaning and care of leather upholstery
Natural leather requires an extra degree of attention and
– Moisten a cotton or woollen cloth with water and wipe
over the leather surfaces.
More stubborn dirt
– More stubborn dirt can be removed using a mild soap
solution (pure liquid soap: two tablespoons dissolved in
one litre of water).
– It is very important not to let the water soak through the
leather or penetrate into the seams.
– Then wipe off with a soft, dry cloth.
Removal of stains
– Remove fresh water-based stains such as coffee, tea,
juices, blood etc. with an absorbent cloth or kitchen roll,
dried-on stains with the cleaning agent from the care set.
– Remove fresh fat-based stains on the surface such as
butter, mayonnaise, chocolate, etc. with an absorbent
cloth or kitchen roll or with the cleaning agent from the
care set.–Treat fat-based, dried-in stains with grease-dissolving
–Treat less common stains such as ball-pen and other
inks, felt-tip pens, nail polish, dispersion paint, shoe
cream etc. with a special leather stain remover.
Leather care products
– The leather should be treated regularly (about twice a
year) with a special leather-care product.
– Apply the cream very sparingly.
– Then wipe off with a soft, dry cloth.

Dust and grit in the pores and seams can have an abrasive effect
and damage the surface of the leather. If the car is left standing in
the sun for long periods, the leather should be protected against
direct sunlight to prevent it from fading. However, slight colour vari-
ations will arise in normal use.

Fuel and filling the tankPetrolPetrol grade
The correct grade of petrol is listed inside the fuel tank
flap.The vehicle is equipped with a catalytic converter and must only be
run on unleaded petrol. Unleaded petrol must comply with the
European EN 228 standard. The petrol grades have different octane
ratings (RON). If, in exceptional circumstances, the correct octane
rating is not available, please note the following:
Your engine normally requires Super Plus unleaded petrol (98 RON)
according to ⇒page 281, “Performance, weights and dimensions”.
Premium unleaded fuel with 95 RON can also be used. This can,
however, result in a slight loss of power under certain driving condi-
tions. If premium unleaded petrol is not available, the engine can be
run on regular unleaded petrol with 91 RON as an emergency
measure. In this case only use moderate engine speeds and a light
throttle. Avoid using full throttle. Fill up with premium or Super Plus
petrol as soon as possible.
Petrol complying with the EN 228 standard can contain small
quantities of ethanol. However, “bioethanol fuels”, which are
retailed under various different names such as E50 and E85, and
which contain a large proportion of ethanol, must not be put into
the vehicle, as this would damage the fuel system.
Even one tankful of leaded fuel would permanently impair the
efficiency of the catalytic converter.
High engine speed and full throttle can damage the engine when
using petrol with an octane rating lower than the correct grade for

itself off as soon as the tank is “full”. Do not try to put in more fuel
after the nozzle cuts out, as this will fill the expansion chamber in
the fuel tank.
The correct fuel grade for your vehicle is given on a sticker on the

Fuel is highly inflammable and can cause serious burns and other
For safety reasons always switch off the auxiliary heating*
before refuelling the vehicle.
For safety reasons we do not recommend carrying a spare fuel
canister in the vehicle. The canister could become damaged in an
accident and leak.
Observe all relevant statutory regulations on using, storing and
transporting spare fuel canisters.
When filling your tank or a spare fuel canister with fuel, do not
smoke and keep away from naked flames. Risk of explosion!
If, in exceptional circumstances, you have to carry a spare fuel
canister, please observe the following warnings:
−Never fill fuel into the spare fuel canister with the canister
placed in or on top of the vehicle. An electrostatic charge could build up during filling, causing the fuel vapour to ignite. Danger
of explosion. Always place the canister on the ground to fill it.
−Insert the filler nozzle as far as possible into the spare fuel
−If the spare fuel canister is made of metal, the filler nozzle
must be in contact with the canister during filling. This helps
prevent an electrostatic charge building up.
−Make sure you never spill fuel in the vehicle or in the luggage
compartment. Fuel vapour is explosive. Risk of fatal accident!
Remove any fuel spills from the paintwork immediately.
Never run the tank completely dry. If there is an irregular fuel
supply, misfiring can occur. As a result unburnt fuel can enter the
exhaust system and cause damage to the catalytic converter(s).For the sake of the environment
Do not try to put in more fuel after the automatic filler nozzle has
