Keep si licone sprays off the windshie ld to avoid wiper smear in
rain. •
Cast (light) alloy wheels
Cast (light) alloy wheels require special care.
-Wash the wheels with a sponge or hose brush every
o ther week.
- For deep clean ing afterwards, use only a dedicated acid­
free cast alloy whee l cleaner.
Rub a coat of liquid wax onto the rims every t hree month .
Be sure to reach and treat all parts of the rim.
To preserve the decorative appearance of the cast alloy wheels,
some special care is necessary. In add ition to road dirt and salt,
brake dust is also corrosive . If left on for too long, brake dust can
cause pitting.
Use on ly special
acid -free cleaners formu lated for a lloy rims . Safe
produc ts are available at your authorized Audi dealer. Never leave
the cleaner on the rims longer than specified on the label. If not rinsed off promptly, the acid contained in some cleaners can attack
the threads on the wheel bolts .
Never use abrasive or metal po lishing c leaning agents. If the protec ­
t ive coating has been chipped, e.g . by kicked up road dirt, touch it
up as soon as possible .

Body cavity sealing
The b ody cavity sealing does not need to b e checked.
All body cavities which could be affected by corrosion have been
thoroughly protected at the factory .
T his seal ing does not require any inspection or add it ional trea t­
ment. If any wax should seep out of the cavity wh en the ambient
t emperature is h igh, i t ca n be removed with a p lastic scrape r and a
suitable solvent.
& WARNING

U.S. DOT Tire Identification Number (TIN) and tire
manufacture date
This is the tire's "serial number". It begins with the letters "DOT"
and indicates that the tire meets all federal standards . The next two
numbers or letters indicate the plant where it was manufactured,
and the last four numbers represent the week and year of manufac ­
ture . For example, the numbers 2208 mean that the tire was
produced in the 22th week of 2008. The other numbers are
marketing codes that may or may not be used by the tire manufac­
turer. This information is used to contact consumers if a tire defect
requires a recall.
Tire ply composition and materials used
The number of plies indicates the number of layers of rubber-coated
fabric in the tire. In general, the greater the number of plies, the
more weight a tire can support. Tire manufacturers also must indi­
cate the materials in the tire, which include steel, nylon, polyester,
and others.
Maximum Load Rating
This number indicates the maximum load in kilograms and pounds
that can be carried by the tire.
Tire quality grading for treadwear, traction, and
temperature resistance
Tread wear, traction and temperature grades~ page 363.
Maximum Permissible Inflation Pressure
This number is the greatest amount of air pressure that should ever
be put in the tire under normal driving conditions.
Replacing tires or rims on vehicles equipped with tire
pressure monitoring system
The wheels on your vehicle are equipped with a sensor which
constantly monitors the air pressure inside the tire, and then trans ­
mits this information to the tire pressure monitoring system. If you
are going to replace the wheel rims on your vehicle, make sure the new rims also have these sensors
. The sensors must be compatible
with the tire pressure monitoring system on your vehicle.
If you install rims, which do not have the sensors, or have sensors
which are not compatible, then the tire pressure monitoring system
will not work properly. In this case, the tire pressure monitoring
system would not be able to monitor the tire pressure or warn you
if it is necessary.
• The battery inside of the tire pressure sensor has a limited
service life.
• Always drive with the valve stem caps securely mounted. We
recommend using factory installed valve stem caps. Ask your autho­
rized Audi dealer to replace lost valve stem caps .
The installation of replacement tires with steel cord body plies in
the tire sidewall may cause malfunction of the tire pressure moni­
toring system, and is not recommended (cord material information
in molded on the tire sidewall).
Always check your tire pressure monitoring system indicator after replacing one or more tires on your vehicle. If the tire pressure
monitoring system indicator flashes, or is on, your system is not
working properly. Your replacement tire might be incompatible with
your tire pressure monitoring system, or some component of the
tire pressure monitoring system may be damaged.
& WARNING
• Using incorrect or unmatched tires and/ or wheels or improper
tire and wheel combinations can lead to loss of control, collision and serious personal injury.
• Always use tires, rims and wheel bolts that meet the specifica­
tions of original factory-installed tires or other combinations that
have been specifically approved by the vehicle manufacturer .
• Tires age even if they are not being used and can fail suddenly,
especially at high speeds. Tires that are more than 6 years old can
only be used in an emergency and then with special care and at
lower speeds . .,.

Wheel bolts
W heel bolt s must alw ays b e tightened t o th e c orr ect
tor que.
The de sign of wheel bo lts is matc hed to the fac to ry instal led rims. If
different rims are fitted, the correct wheel bo lts with the right length
and correctly shaped bolt heads must be used . This ensures that
w hee ls are fitted securely and that t he b rake sys tem functions
co rrectly.
I n certain circums ta nces, you may not use w heel bo lts fr om a
different vehicle -even if it is the same model=>
page 403.
& WARNING
Improperly tightened or mainta ined wheel bolts can become loose
causing loss of control , a colli sion and serious per sonal injury .
• Always keep the wheel bolts and the threads in the wheel hubs
clean so the wheel bolts can turn easily and be properly tightened.
• Never grease or oil the wheel bolts and the threads in the wheel
hubs. They can become loose while d riving if greased or oiled ,
even if tightened to the specified torque.
• Only use wheel bolts that belong to the rim being installed .
• Never use different wheels bolts on your vehicle.
• Always maintain the correct t ightening torque for the wheel
bolts to reduce the risk of a wheel lo ss.
If the tightening torque of
the wheel bolts is too low, they can loosen and come out when the
vehicle is moving . If the tightening torque is too high, the wheel
bolts and th reads can be damaged and the wheel can become
loose .

0 Note
The specified torque for the wheel bolts is 120 ft lb (160 Nm) with a
tolerance of± 7,4 ft lb(± 10 Nm). Torque wheel bolts diagonally.
After changing a wheel, the torque must be checked as soon as
possible with a torque wrench -preferably by an authorized Audi
dealer or qualified workshop. •
Low aspect ratio tires
Your Audi is factory-equipped with low aspect ratio tires. These tires
have been thoroughly tested and been selected specifically for your
model for their superb performance, road feel and handling under
a variety of driving conditions . Ask your authorized Audi dealer for
more details.
The low aspect ratio of these tires is indicated by a numeral of
55 or
less
in the tire's size designation. The numeral represents the ratio
of the tire's sidewall height in relation to its tread width expressed
in percentage. Conventional tires have a height/width ratio of 60 or
more.
The performance of low-aspect-ratio tires is particularly sensitive to
improper inflation pressure. It is therefore important that low
aspect ratio tires are inflated to the specified pressure and that the
inflation pressure is regularly checked and maintained. Tire pres­
sures should be checked at least once a month and always before a
long trip~
page 353, "Checking tire pressure".
What you can do to avoid tire and rim damage
Low aspect ratio tires can be damaged more easily by impact with
potholes, curbs, gullies or ridges on the road, particularly if the tire
is underinflated.
In order to minimize the occurrence of impact damage to the tires
of your vehicle, we recommend that you observe the following precautions: •
Always maintain recommended inflation pressures. Check your
tire pressure every 2,000 miles (3,000 km) and add air if necessary.
• Drive carefully on roads with potholes, deep gullies or ridges.
The impact from driving through or over such obstacles can
damage your tires. Impact with a curb may also cause damage to
your tires.
• After any impact, immediately inspect your tires or have them
inspected by the nearest authorized Audi dealer. Replace a
damaged tire as soon as possible.
• Inspect your tires every 2,000 miles (3,000 km) for damage and
wear. Damage is not always easy to see. Damage can lead to loss of
air and underinflation, which could eventually cause tire failure. If
you believe that a tire may have been damaged, replace the tire as
soon as possible.
• Th ese tires may wear more quickly than others.
• Please also remember that. while these tires deliver responsive
handling, they may ride less comfortably and make more noise than
other choices.
Reduced performance in winter/cold season
conditions
All tires are designed for certain purposes. The low aspect ratio,
ultra high performance tires originally installed on your vehicle are
intended for maximum dry and wet road performance and handling.
They are not suitable for cold, snowy or icy weather conditions. If
you drive under those circumstances, you should equip your vehicle
with all -season or winter tires, which offer better traction under
those conditions. We suggest you use the recommended snow or all -season tires specified for your vehicle, or their equivalent.
Refer to~
page 363for more detailed information regarding winter
tires. •
