Save electrical energy
The engine drives the alternator to generate electricity. This means
that fuel consumption rises when more power is required for elec-
trical equipment. Switch off electrical equipment when it is not
needed. Electrical equipment which uses a lot of electricity includes
the blower (at a high se
tting), the rear window heating and the seat
heating*.

Care of vehicle and cleaning
246Plastic 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 321 .
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.

Wheels and tyres
270Tread wear indicators
The tread wear indicators show the condition of the tyre
treads.The original tyres on your vehicl e have 1.6 mm high “tread wear
indicators” ⇒fig. 262 running across the tread. Depending on the
make, there will be 6 to 8 of them spaced at equal distances around
the tyre. Markings on the tyre sidewa ll (for instance the letters “TWI”
or a triangle) indicate the positi ons of the tread wear indicators.
The minimum tread depth required by law in Germany is 1.6 mm
(measured in the tread grooves next to the tread wear indicators).
Other specifications may apply in export countries.
WARNING
To avoid putting safety at risk, the tyres must be replaced at the
latest when the tread is worn down to the tread wear indicators.•
Especially in difficult driving conditions such as wet or icy
roads, it is important that the tyres have sufficient tread depth.
The tread depth should same on th e tyres of both the front and the
rear axles.
•
The decrease in driving safety due to insufficient tread depth is
particularly evident in vehicle handling, when there is a risk of aquaplaning in deep puddles of wa
ter and when driving through
corners. Braking is also adversely affected.
•
The speed has to be adapted accordingly, otherwise there is a
risk of losing control over the vehicle.
Changing wheels roundTo ensure that the wear is equal on all tyres the wheels should be
changed round from time to time according to the system
⇒ fig. 263. All the tyres will then last for about the same time.Replacing wheels and tyres
It is important to use the correct wheels and tyres when
replacement is necessary.– All four wheels must be fitted with tyres of the same type,
size (rolling circumference) and preferably the same
tread pattern.
– If possible, tyres should be re placed at least in pairs and
not individually (i.e. both front tyres or both rear tyres
together).

Technical data
In winter road conditions winter tyres will considerably improve the
car's handling. Due to their type
of construction (width, rubber
compound, tread pattern), summer tyres give less grip on ice and
snow. This applies particularly to vehicles equipped with wide
section tyres or high speed tyres (code letters H, V or Y on the side-
wall).
Only use winter tyres of the correct type approved for your vehicle.
The sizes of the winter tyres approved for your vehicle are listed in
the vehicle's documents (e.g. EC Certificate of Conformity or COC
document
4)). The vehicle documents vary depending on the
country of residence. Also refer to ⇒page 270 , ⇒ page 270 .
Winter tyres are no longer fully effective when the tread is worn
down to a depth of 4 mm.
The performance of winter tyres is also severely impaired by ageing,
even if the tread is still much deeper than 4 mm.
Winter tyres are subj ect to the following maximum speed limits
according to speed rating code letter: ⇒
In Germany vehicles capable of exceeding these speeds must have
an appropriate sticker attached so it is visible to the driver. Suitable
stickers are available from Audi dealers and specialist retailers.
Please note regulations to this effect in your country. “All-weather” tyres can also be used instead of winter tyres.
Using winter tyres with V-rating
Please note that the generally applicable 240 km/h speed rating for
winter tyres with the letter "V" is subject to
technical restrictions;
the maximum permissi ble speed for your vehicle may be signifi-
cantly lower. The maximum speed limit fo r tyres with a V-rating
depends directly on the maximum axle weights for your car and on
the listed weight rating of the tyres being used.
It is best to contact an Audi dealer to check the maximum speed
which is permissible for the V-rated tyres fitted on your car on the
basis of this information.
WARNING
Exceeding the maximum speed per mitted for the winter tyres
fitted on your car can cause tyre failure, resulting in a loss of
control of the vehicle – risk of accident.
For the sake of the environment
Summer tyres should be fitted again as soon as possible; they give
better handling on roads which are free of snow and ice. Summer
tyres produce less rolling noise, do not wear down as quickly and,
most importantly, reduce fuel consumption.Snow chains
Snow chains will improve the vehicle's handling on snow-
covered roads.– Snow chains can be used on the front wheels only.
– Keep your speed below 50 km/h.Snow chains will improve braking ability as well as traction in winter
conditions.

Wheels and tyres
274For technical reasons snow chains may only be used on tyres with
certain wheel rim/tyre combinations.
Only use snow chains with fine-pitch links. The links must not
protrude more than 13.5 mm from the tyres (including tensioner).
Remove the chains when roads are free of snow. Otherwise they will
impair handling, damage the tyres and wear out very quickly.
Four-wheel drive : where snow chains are compulsory on certain
roads, this normally also applies to cars with four-wheel drive. Snow
chains may only be fitted to the front wheels (also on vehicles with
four-wheel drive).Run flat tyresApplies to vehicles: with run flat tyresIntroduction
Run flat tyres allow you to co ntinue your journey in the
event of a loss of tyre pressure.Run flat tyres have reinforced sidewalls which support the tyre in
the event of a loss of pressure.
Run flat tyres must only be used on vehicles which were already
factory-fitted with these tyres and which also have a tyre pressure
monitoring system*.
Run flat tyres can be identified by the marking “RSC” (Runflat
System Component) on the sidewall. If you change the tyres on your vehicle from regular tyres to run flat
tyres or vice-versa, the control unit must be reprogrammed by an
Audi dealer or other qualified workshop.
What are the benefits of run flat tyres?
Run flat tyres ensure that you remain mobile, even in the event of a
loss of tyre pressure. In favourable conditions these tyres have an
operating range of
at least 30 km, however the vehicle must not be
driven faster than 80 km/h ⇒ in “Driving with run flat tyres” on
page 275 .
The tyre pressures are constantly checked by the tyre pressure
monitoring system. When the run flat system becomes active
(centre display), it is still the driver's responsibility to check the
tyre(s) affected and to decide whether it is possible to continue
driving. Also refer to ⇒page 275, “Driving with run flat tyres”.
When is it no longer possibl e to continue driving with
the help of the run flat tyres?
•
If the Electronic Stabilisation Program (ESP) is out of operation
or is triggered continuously.
•
If the tyre pressure monitoring system is out of operation.
•
If one of the tyres has been severely damaged in an accident, etc.
If a tyre has been badly damaged there is a risk that parts of the
tread can be thrown off and cause damage to the fuel lines, brake
pipes or fuel filler.
•
You must stop driving if severe vibrations occur, or if the wheel
starts overheating and gives off smoke.
•
You must also stop driving if damage to the tyres (e.g. tears in
the sidewalls) becomes apparent.
WARNING
Please ask your Audi dealer or qualified workshop whether run flat
tyres can be used on your vehicle. Unauthorised use of these tyres
can invalidate the vehi cle's type approval for use on public roads.

Technical data
Furthermore, this could cause damage to your vehicle and
possibly also result in an accident.
Note
•
If you cannot continue driving even with run flat tyres please
obtain professional assistance.
•
You should obtain professional assistance if you are in any doubt
regarding the rims and tyres for your vehicle.
Applies to vehicles: with run flat tyresDriving with run flat tyres
Please remember that the vehicle's handling will be
impaired.Driving a vehicle with a deflat ed tyre, or with insufficient
tyre pressure, is an abnormal situation. However, since the
handling of a vehicle equipped with run flat tyres is only
slightly impaired, it is important to remember that you are
driving with a deflated tyre. If you have to make use of the
run flat system please remember the following points:
– The Electronic Stabilisation Program (ESP) must be switched on.
–Do not exceed 80km/h ⇒.
– Anticipate the traffic situation well in advance.
– Be careful when accelerating.
– Avoid unnecessary braking and steering manoeuvres.
– Reduce speed in good time before corners and potential hazards.
Please refer to ⇒page 274, “ When is it no longer possible to
continue driving with the help of the run flat tyres?”
Effects on handling when dr iving with defective tyres
If one of the front tyres is defective , your vehicle will tend to pull
slightly towards that side and braking performance will be
impaired.
A defective rear tyre will also make the vehicle pull slightly to one
side, and the braking response will again be slightly impaired.
These effects will be most noticeable when driving in a corner.
WARNING
•
When using the run flat system the changes in vehicle handling
will be noticeable when braking, in corners and during fast accel-
eration.
•
The maximum permitted speed of 80 km/h is subject to road
and weather conditions. Always observe the relevant rules and
regulations. Run flat tyres allow you to continue your journey in
the event of a loss of tyre pressu re. However, the driver remains
responsible for the safety of the vehicle and for restoring the
correct tyre pressure and having defective parts replaced
⇒ page 276 . For these reasons you should always adjust your
driving to suit the circumstances.Caution
We recommend that you drive with great care when making use of
the run flat system. Avoid abrupt manoeuvres.

Wheels and tyres
276Applies to vehicles: with run flat tyresRenewing defective components on run flat tyres
The run flat tyres have been specially developed for your
vehicle and matched to its requirements.Use and combine only the approved run flat tyres and rims. It is not
permissible to combine standard wheels and run flat tyres ⇒.
If you have to drive with low ty re pressure or with a completely
deflated tyre, you should always ta ke the vehicle to an authorised
qualified workshop and have the defective parts inspected and the
condition corrected.
WARNING
•
We recommend that you have the run flat tyre renewed and
also have the rim checked by a qual ified workshop to identify any
damage.
•
Using tyres or rims which have not been approved can cause
damage to the vehicle. Vehicle handling can be impaired and
driving safety can no longer be guar anteed. This can also void the
vehicle's certification for use on public roads.Note
Run-flat tyres can be repaired with the TMS ⇒page 285 .
