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.
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 interiorSound system / MMI* display screen and MMI control console*The 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.
Caution
To avoid scratching the screen, do not wipe the display with a dry
cloth.
•
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.
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.
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

Wheels and tyres 272replacement parts, trained personnel and facilities for disposing of
the old tyres.
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 292.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.

– Now fit the crank handle onto the jack by inserting it
in the opening on the knob ⇒page 290, fig. 274. Turn the
crank handle clockwise or anti-clockwise to secure it in
place.
– Raise the vehicle by winding the crank handle until the
defective wheel is clear of the ground.Recesses at the front and rear of the door sills mark the jacking
points ⇒page 290, fig. 273. There is one jacking point for each
wheel. The distance from the jacking points to the wheel arches is
approximately 20 cm at the front and 40 cm at the rear. The jack may
only be applied at the seam of the jacking points shown.
An unstable surface under the jack may cause the vehicle to slip off
the jack. Always provide a firm base for the jack on the ground. If
necessary use a large, strong board or similar support. On a hard,
slippery surface (such as tiles) use a rubber mat or similar to prevent
the jack from slipping.
WARNING
•
Prevent the base of the jack from slipping – risk of injury.
•
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.
Taking off the wheel and putting on the spare wheel
Step-by-step instructions for taking off the wheel and
putting on the spare wheel.Change the wheel as described below after loosening the

– Screw in the mounting pin (provided in the vehicle's tool
kit) by hand in place of the wheel bolt ⇒page 291,
fig. 276.
– Then unscrew the other wheel bolts as described above.
– Take off the wheel. The mounting pin stays where it is.
Putting on the spare 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.
– Carry out the steps required after you have changed the
wheel ⇒page 289, “After changing a wheel”.The wheel bolts should be clean and turn easily. Before putting on
the spare wheel, inspect the condition of the wheel and hub
mounting surfaces. These surfaces must be clean before mounting
the wheel.
The wheel bolts are easier to remove from the wheel rim if you use
the hexagonal socket in the screwdriver handle. The reversible
screwdriver blade should be removed as a precautionary measure
when the tool is used for this purpose.
Note the direction of rotation when putting on a tyre with direc-
tional tread pattern ⇒page 292.
Note
Do not use the hexagonal socket in the screwdriver handle to loosen
or tighten the wheel bolts.
Tyres 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.
Drive carefully should you ever have a puncture and have to mount
the spare wheel so it rotates in the wrong direction. This is because
the tyre will not give optimum performance. Bear this in mind
particularly when driving on wet roads.
To benefit from the advantages of tyres with this type of tread
pattern, the defective tyre should be replaced and refitted as soon
as possible so that all tyres again rotate in the correct direction.Applies to vehicles: with anti-theft wheel boltsAnti-theft wheel bolts
