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 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.

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 continue 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 possible 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 vehicle's type approval for use on public roads.

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 deflated 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 driving 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 pressure. 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 tyre pressure or with a completely
deflated tyre, you should always take 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 qualified 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 guaranteed. 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.

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
safety, lead to excessive wear of components, and also invalidate
the type approval for your vehicle.
You will appreciate that your Audi dealer cannot be held liable for
any damage caused by modifications and/or work performed incor-
rectly.
We recommend that all work should be performed by an Audi work-
shop using Audi Genuine parts

Accessories and modifications to the vehicle 278Radio transmitters and business equipmentRadio transmitters (fixed installation)
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.
