The tread wear indicators show the condition of the tyre
treads.The original tyres on your vehicle have 1.6 mm high “tread wear
indicators” ⇒fig. 220 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 sidewall (for instance the letters “TWI”
or a triangle) indicate the positions 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 the 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 water 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. 221. 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 replaced at least in pairs and
not individually (i.e. both front tyres or both rear tyres
together).

WARNING
•
It is very important to ensure that the tyres you have chosen
have adequate clearance. When selecting replacement tyres, do
not rely entirely on the nominal tyre size marked on the tyre; with
some makes of tyre the effective tyre size can differ significantly
from the nominal dimensions, even though the tyres have the
same size designation. Inadequate tyre clearance can result in
damage to the tyres or the vehicle, causing a serious safety risk. It
may also invalidate the vehicle's type approval for use on public
roads.
•
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 vehicle's type approval for use on public
roads. Furthermore, this could cause damage to your vehicle and
possibly also result in an accident.
•
Avoid running the car on tyres that are more than 6 years old.
If you have no alternative, you should drive slowly and with extra
care at all times.For the sake of the environment
Old tyres must be disposed of according to the laws in the country
concerned.
Note
•
Never mount used tyres if you are not sure of their previous
history.
•
For technical reasons it is not normally possible to use wheel
rims from other vehicles. In some cases this also applies to rims
from other vehicles of the same model.
Wheel bolts
The wheel bolts are designed to suit the rims on your car.The wheel bolts are matched to the rims. When installing different
wheels (for instance wheels with winter tyres) it is important to use
the correct wheel bolts with the right length and correctly shaped
bolt heads. This is essential for the secure fit of the wheels and for
the proper function of the brake system.
Audi dealers have full information on the technical requirements
when installing or changing tyres, rims or wheel trims.
The wheel bolts should be clean and turn easily.
A special adapter is required to turn the anti-theft wheel bolts*
⇒page 254.Winter tyres
Winter tyres will significantly improve the car's handling
in winter road conditions.–Use only radial ply winter tyres.
– Winter tyres must be fitted on all four wheels.
– Only use winter tyres of the correct type approved for
your vehicle.
– Please note that the maximum permissible speed for
winter tyres may be lower than for summer tyres.
– Also note that winter tyres are no longer effective when
the tread is worn down.
– After fitting the wheels you must always check the tyre
pressures. The correct tyre pressures are listed on the
sticker on the end face of the driver's door.

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
6)). The vehicle documents vary depending on the
country of residence. Also refer to ⇒page 234.
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 subject 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 permissible speed for your vehicle may be signifi-
cantly lower. The maximum speed limit for 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 permitted 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.

Accessories and modifications to the vehicleAccessories and replacement partsAlways ask your dealer or specialist retailer for advice
before purchasing accessories and replacement parts.Your car is designed to offer a high standard of active and passive
safety. For this reason, we recommend that you ask an Audi dealer
for advice before fitting accessories or replacement parts. Audi
dealers have the latest information from the manufacturer and can
recommend accessories and replacement parts which are suitable
for your requirements. They can also answer any questions you
might have regarding official regulations.
We recommend you to use only Audi accessories and Audi Genuine
parts
®. Audi has tested these parts and accessories for suitability,
reliability and safety. Audi dealers have the necessary experience
and facilities to ensure that the parts are installed properly.
Although the market is constantly scrutinised, Audi cannot judge or
assume responsibility for the reliability, safety and suitability of
non-genuine products - even though in some instances, these parts
may have been approved by an officially recognised technical
testing authority or accompanied by an official approval certificate.
Any retro-fitted equipment which has a direct effect on the vehicle
and/or the way it is driven (e.g. cruise control system or electroni-
cally-controlled suspension) must be approved for use in your
vehicle and bear the e mark (the European Union's approval
symbol).
If any additional electrical components are fitted which do not serve
to control the vehicle itself (for instance a refrigerator box, laptop or
ventilator fan, etc.), these must bear the CE mark (manufacturer
conformity declaration in the European Union).
WARNING
Never attach accessories (such as cup holders or telephone
brackets) to the surfaces covering the airbag units or the areas
around the airbags: this could cause injury if the airbag is
triggered.ModificationsModifications must always be carried out according to
our specifications.Unauthorised modifications to the electronic components or soft-
ware in the vehicle may cause malfunctioning. Due to the way the
electronic components are linked together in networks, other
systems may be affected by the faults. This can seriously impair

Retrofit installations of radio transmitters in the vehicle are subject
to official approval. Audi generally authorises in-vehicle installa-
tions of approved types of radio transmitters provided that:•
the aerial is installed correctly,
•
the aerial is not installed in the interior of the vehicle (and
screened cables are used together with non-reflective aerial trim-
ming),
•
the effective transmitting power does not exceed 10 Watts at the
aerial base.
Audi dealers and specialist retailers will be able to inform you about
options for installing and operating radio transmitters with a higher
transmitting power.
Mobile radio transmitters
When using commercial mobile telephones or radio equipment it is
possible that they might interfere with the electronics of your
vehicle and cause malfunctions. The reasons could be:
•
no external aerial
•
external aerial incorrectly installed
•
transmitting power more than 10 W.
Therefore you must not operate portable mobile telephones or radio
equipment inside the vehicle without a correctly installed external
aerial ⇒.
Please note also that the maximum range of the equipment can only
be achieved with an external aerial.
Business equipment
Retrofit installation of business or other equipment in the vehicle is
permitted, provided the equipment cannot interfere with the driver's immediate control of the vehicle. Any such equipment must
carry the CE mark. Any retrofit equipment that could influence the
driver's control of the vehicle must have a type approval for your
vehicle and must carry the e mark.
WARNING
Mobile telephones or radio equipment which are operated inside
the vehicle without a correctly installed external aerial can create
excessive magnetic fields that could cause a health hazard.
Note
•
Any retrofit installation of electrical or electronic equipment in
the vehicle will affect its type approval. In extreme cases this could
mean that you might lose the type approval for your vehicle.
•
Please refer to the mobile telephone/radio operating
instructions.

Technical data How to use the compact temporary spare wheel
Should you ever have a punctured tyre, the compact temporary
spare wheel is only intended for temporary use until you can reach
a workshop. The standard-size road wheel should be refitted as
soon as possible.
Please note the following restrictions when using the compact
temporary spare wheel. The compact temporary spare wheel is
designed specifically for this model. For this reason, do not use a
temporary spare from a different type of vehicle.
Snow chains
For technical reasons, snow chains must not be used on the
compact temporary spare wheel.
If you should have a puncture on one of the front wheels when using
snow chains, fit the compact temporary spare in place of one of the
rear wheels. You can then attach the snow chains to the wheel taken
from the rear and use this wheel to replace the punctured front
wheel.
WARNING
•
The tyre pressures must be checked and corrected as soon as
possible. The tyre pressure of the compact temporary spare wheel
must be 4.2 bar – an incorrectly inflated tyre can cause an acci-
dent.
•
Do not drive faster than 80 km/h - higher speeds can cause an
accident.
•
Avoid heavy acceleration, hard braking and fast cornering – risk
of accident.
•
Never use two or more compact spare tyres at the same time –
risk of accident.
•
No other type of tyre (normal summer or winter tyres) may be
fitted on the compact temporary spare wheel.
Ty r e r e p a i r sGeneral information and safety notes
Repaired tyres are only suitable for temporary use.Your vehicle is equipped with a tyre repair kit: the Tyre Mobility
System (TMS).
In the event of a puncture you will find the TMS, which consists of a
sealing compound and a compressor, located under the floor panel
in the luggage compartment.
The TMS will reliably seal tyres damaged by foreign bodies,
provided that the cuts or punctures are no larger than approx. 4 mm
in diameter.
It is not necessary to remove the foreign body from the tyre.
The sealing compound must not be used:•
on cuts and punctures larger than 4 mm ⇒fig. 227
•
if the wheel rim has been damaged
•
if you have been driving with very low pressure or a completely
flat tyre .
How to use the TMS is described in the section Repairing a tyre
⇒page 248 and in the instructions supplied with the tyre sealant
can.
