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 on the doors, windows, engine lid and luggage
lid will remain pliable and last longer if they are occasionally treated
with a suitable care product (for example silicone 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.
After washing, the wheels should only be cleaned with an "acid-
free" cleaning agent for alloy wheels. This is available from Audi R8
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.
WARNING
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 interiorPlastic 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.Applies to vehicles: with carbon partsCarbon par tsThe carbon parts on your vehicle have a painted surface. They do
not need any special care and are cleaned just like plastic parts
⇒page 147.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.
Normal cleaning
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.

Wheels and tyres 166Wheels and tyresWheelsGeneral notes–When driving with new tyres, be especially careful during
the first 500 km.
– If you have to drive over a kerb or similar obstacle, drive
very slowly and as near as possible at a right angle to the
kerb.
– Inspect the tyres regularly for damage (cuts, cracks or
blisters, etc.). Remove any foreign bodies embedded in
the treads.
– Damaged wheels and tyres must be replaced immedi-
ately.
– Keep grease, oil and fuel off the tyres.
– Replace any missing valve caps as soon as possible.
– Mark the wheels before taking them off so that they
rotate in the same direction when put back.
– When removed, the wheels or tyres should be stored in a
cool, dry and preferably dark place.New tyres
New tyres do not give maximum grip straight away and should
therefore be “run in” by driving carefully and at moderate speeds for
about the first 500 km. This will also help to make the tyres last
longer.
The tread depth of new tyres may vary, according to the type and
make of tyre and the tread pattern.Concealed damage
Damage to tyres and rims is often not readily visible. If you notice
unusual vibration or the car pulling to one side, this may indicate
that one of the tyres is damaged. Reduce speed immediately if there
is any reason to suspect that damage may have occurred. Inspect
the tyres for damage. If no external damage is visible, drive slowly
and carefully to the nearest qualified workshop and have the car
inspected.
Tyres with directional tread pattern
An arrow on the tyre sidewall indicates the direction of rotation on
tyres with directional tread. Always note the direction of rotation
indicated when mounting the wheel. This guarantees optimum grip
and helps to avoid aquaplaning, excessive noise and wear.
Wheels with bolted rim flange*
Light-alloy wheels with a bolted rim flange consist of several
components. A special technique is applied to bolt these compo-
nents together. Apart from safety and true running this also ensures
that the wheel functions correctly and that there is no leakage.
Damaged rims must therefore be replaced; you must never attempt
to repair or dismantle them ⇒.
Wheels with bolted trim parts*
Light-alloy wheels can be fitted with interchangeable trim parts
which are attached to the rim using self-locking bolts. Should you
wish to replace damaged trim parts please contact a qualified work-
shop.
WARNING
Never remove the bolts on a wheel with bolted rim flange* (acci-
dent risk).

Wheels and tyres 170•
If wheel trims are fitted after the car is purchased, ensure that
there is an adequate flow of air for cooling the brakes.For the sake of the environment
Old tyres must be disposed of according to the laws in the country
concerned.
Note
•
Tyres with the “R0” mark are specially matched to your Audi. We
recommend that you use these tyres only. Your Audi R8 dealer or
specialist retailer will gladly provide you with further information.
•
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 alloy wheels or 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 R8 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 182.
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 driver's door pillar ⇒page 167.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
3)). The vehicle documents vary depending on the
country of residence. Also refer to ⇒page 168.
Winter tyres are no longer fully effective when the tread is worn
down to a depth of 4 mm.
WARNING (continued)
3)COC = Certificate of conformity

Wheels and tyres 172Remove wheel covers (if fitted) and trim rings before attaching
snow chains. For safety reasons cover caps must then be fitted over
the wheel bolts. These are available from Audi R8 dealers.
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 rear wheels (also on vehicles with
four-wheel drive).Tyre pressure monitoring systemApplies to vehicles: with tyre pressure monitoring systemIntroduction
The tyre pressure monitoring system keeps a check on the
inflation pressures of the four road wheels while you are
driving.The system warns the driver in the event of a loss of pressure by
means of symbols and messages in the instrument cluster display.
The system employs sensors on the wheels. The radio signals from
these sensors are transmitted to the tyre pressure monitoring
system.
Please bear in mind that the tyre inflation pressure is also influ-
enced by the temperature of the tyre. For every 10°C increase in the
tyre temperature the pressure will normally increase by about
0.1 bar. The tyre heats up while the vehicle is being driven and the
tyre pressure will rise accordingly. For this reason, you should only
adjust the tyre pressures when they are cold (i.e. approximately at
ambient temperature).
To ensure that the tyre pressure monitoring system works reliably,
you should check and, if necessary, adjust the tyre pressures at
regular intervals.The tyre pressures recommended for your vehicle are given on the
sticker attached to the driver's door pillar.
Initialising the tyre pressure monitoring system
The inflation pressures for two sets of wheels (e.g. with winter and
summer tyres) are stored on your vehicle. You can change between
these two sets of wheels any number of times without re-initialising
the system.
The tyre pressure monitoring system must be re-initialised by your
Audi R8 dealer if a new set of wheels is used or the electronic
sensors are renewed.
Warning lamp
 lit
If the tyre pressure is more than 0.5 bar below the reference value,
the display will show the tyre symbol
 with a corresponding
message, such as Tyre pressures too low ⇒.
WARNING
•
If the warning lamp
 lights up you must slow down immedi-
ately and avoid any severe braking or steering manoeuvres. As
soon as you can do so safely, stop and check the tyres and the tyre
pressures.
•
Never re-adjust the tyre inflation pressure when the tyre is hot.
This can cause serious damage to the tyre or even a blow-out,
which could result in an accident.
•
Under-inflated tyres flex more and can overheat at continuous
high speeds. This can cause tread separation and tyre blow-out,
which could result in an accident.For the sake of the environment
Under-inflated tyres lead to increased fuel consumption and tyre
wear.

Note•
Do not use the compressor for longer than 8 minutes at a time,
as it could overheat. When the compressor has cooled down, you
can use it again.
•
If tyre sealant should leak out, leave it to dry and then pull it off
like foil.
Final checkAfter covering a short distance it is necessary to check the
tyre pressure
– After about 10 minutes stop to check the tyre pressure.
– If tyre pressure is still at least 1.3 bar, pump the tyre up
to the pressure specified (see driver's door pillar) and
drive to the nearest workshop to have the tyre and the
tyre sealant can replaced.
– If tyre pressure is less than 1.3 bar, the tyre is too badly
damaged. Do not drive on. You should obtain profes-
sional assistance.
WARNING
If tyre pressure is less than 1.3 bar after driving about 10 minutes,
the tyre is too badly damaged. Do not drive on. You should obtain
professional assistance.
Note
After carrying out repairs to a tyre, have the tyre sealant can
replaced by a qualified dealer. This will ensure that the Tyre Mobility
System is operative again.
Changing a wheelTyres with directional tread pattern
Tyres with directional tread pattern must be mounted so
that they rotate in the correct direction.A directional tread pattern is identified by arrows on the sidewall
pointing in the forward running direction. Always note the direction
of rotation indicated when mounting the wheel. This is important so
that these tyres can give maximum grip and avoid excessive noise,
tread wear and aquaplaning.Applies to vehicles: with anti-theft wheel boltsAnti-theft wheel bolts

The car can be damaged if the jack is not applied at the correct
jacking points. There is also a risk of injury since the jack can slip
off suddenly if it is not properly engaged.Caution
A trolley jack or lifting platform must not be applied at the points
shown ⇒page 183, fig. 128 -arrows-.Taking off / putting on the wheel
Step-by-step instructions for taking off and putting on the
wheel.Change the wheel as described below after loosening the
wheel bolts and raising the vehicle with the jack.
Taking off the wheel
–Using the hexagonal opening in the screwdriver handle
(provided in the vehicle's tool kit), unscrew the wheel bolt
nearest to the top and place the bolt on a clean surface.–Screw in the mounting pin (provided in the vehicle's tool
kit) by hand in place of the wheel bolt ⇒fig. 130.
– Then unscrew the other wheel bolts as described above.
– Take off the wheel ⇒. The mounting pin stays where
it is.
Putting on the wheel
– Put on the spare wheel, using the mounting pin to guide
it into place ⇒.
– Screw in the wheel bolts and tighten them lightly using
the hexagonal opening in the screwdriver handle.
– Then unscrew the mounting pin and tighten the
remaining wheel bolt lightly.
The wheel bolts should be clean and turn easily. Before putting on
the wheel, inspect the condition of the wheel and hub mounting
surfaces. These surfaces must be clean before mounting the wheel.
The hexagonal opening in the screwdriver handle makes it easier to
turn the wheel bolts when they are loose. The reversible screwdriver
blade should be removed when the tool is used for this purpose.
Note the direction of rotation when putting on a tyre with direc-
tional tread pattern ⇒page 182.
Caution
When removing/fitting the wheel the rim may hit and damage the
brake disc. For this reason, please take care and get a second person
to assist you.

•
Do not use the hexagonal socket in the screwdriver handle to
loosen or tighten the wheel bolts.
•
If you notice that the wheel bolts are corroded and difficult to
turn, they must be replaced before having the tightening torque
checked.
•
In the interest of safety, drive at moderate speeds until the tight-
ening torque of the wheel bolts has been checked.
Jump-startingBefore starting the engine
If necessary, the engine can be started by connecting it to
the battery of another vehicle.If the engine should ever fail to start because of a discharged
battery, the battery can be connected to the battery of another
vehicle to start the engine. Suitable jump leads are required.
Both batteries must be rated at 12 Volts. The capacity (Ah) of the
booster battery should not be significantly lower than that of the
discharged battery.
Jump leads
The jump leads must be heavy enough to carry the starter current.
Refer to the details given by the manufacturer.
Only use jump leads with insulated battery clamps.
Positive cable – usually red
Negative cable – usually black
WARNING
•
When it is discharged the battery can freeze at temperatures
around 0°C. A frozen battery must first be thawed out before
connecting the jump leads, as it could otherwise explode.
•
Please note the safety warnings referring to working in the
engine compartment ⇒page 155.Note
•
There must be no contact between the two vehicles as otherwise
current could flow as soon as the positive terminals are connected.
•
The discharged battery must be properly connected to the
vehicle's electrical system.
