make, there will be six to eight of them evenly placed around the
tire. Marks on the tire sidewall (for example "TWI" or other symbols)
indicate the positions of the tread wear indicators. Worn tires must
be replaced. Different figures may apply in other countries=>& .
Tire pressure
Incorrect tire pressure causes premature wear and can cause
sudden tire blow-out. For this reason, tire pressure must be checked
at least once a month =>
page 353.
Driving style
Driving fast around curves, heavy acceleration and hard braking
increase tire wear.
Rotating tires for more even wear
For all four tires on your vehicle to have the same service life, we
recommend that the front and rear tires are rotated according to the
tire manufacturer's suggested tire rotation intervals. Please
remember the following:
• Tire rotation intervals may differ from the vehicle service inter­
vals outlined in your Warranty
& Maintenance booklet.
• The longer one tire is used in one location on the vehicle , the
more it wears at certain points; therefore, we recommend that you
follow the tire manufacturer's suggested tire rotation intervals .
• Vehicles with front-wheel drive experience more tread wear on
the front wheels compared to all-wheel drive (quattro ®l.
• Please rotate tires as shown =>
page 357, fig. 294.
• Extra care must be taken when rotating direction-specific tires
=>
page 379.
Wheel balancing
The wheels on new vehicles are balanced. However, various situa­
tions during everyday driving can cause them to become unbal ­
anced, resulting in vibrations you can usually feel through the
steering wheel. Unbalanced
wheels must be rebalanced to avoid excessive wear on
steering, suspension and tires. A wheel must also be rebalanced
when a new tire is installed.
Incorrect wheel alignment
Incorrect wheel alignment can cause excessive tire wear , impairing
the safety of the vehicle. If tires show excessive wear, have the
wheel alignment checked by an authorized Audi dealer or qualified
workshop.
All Wheel Drive
Vehicles with quattro® must always have tires of the same size,
construction and tread type. For details see=>
page 294.
& WARNING
Sudden tire failure can lead to loss of control, a crash and serious
personal injury!
• Never drive a vehicle when the tread on any tire is worn down
to the wear indicators.
• Worn tires are a safety hazard, they do not grip well on wet
roads and increase your risk of "hydroplaning" and loss of control.
• Always keep chemicals that can cause tire damage, such as
grease, oil, gasoline and brake fluid away from tires .
• 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 .
• Never mount used tires on your vehicle if you are not sure of
their "previous history." Old used tires may have been damaged
even though the damage cannot be seen that can lead to sudden
tire failure and loss of vehicle control. •

& WARNING
Using the wrong snow chains for your vehicle or in stalling them
incorrectly can increase the risk of loss of control leading to
serious personal injury.
• Snow ch ains are available in different sizes . Always make sure
to follow the instructions provided by the snow chain manufac ­
turer .
• When driving with snow chains never drive faster than the
speed permitted for your specific snow chains .
• Always observe local regulations .
0 Note
• Remove sn ow chai ns b efore d rivin g on roads not cove red w ith
snow to avoid damaging tires and wearing the snow chains down
u n n ecessa r i ly.
• Snow chains , which come into d irect contact with t he whee l rim,
ca n scratc h or da mage it. T herefore, ma ke sur e tha t th e snow chains
are suitably covered. Check the position of the snow chains after
dr ivin g a few yards and co rrect if necessa ry . Fo llo w t he instructio ns
from the snow cha in manufacturer when doing so.
• If th e Adapt ive A ir Sus pens io n* shou ld malfunction, do no t
mount or use snow chains because the vehic le wi ll be extremely

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 .

mission parts which an owner can perform.
Maintenance, adjustments and repairs usually require special tools,
testing dev ices and other equipment ava ilable to specially trained
workshop personnel in order to assure proper performance, reli ­
ability and safety of the vehicle and its many systems.
Improper maintenance, adjustments and repairs can impair the
ope ration and re liability of your vehic le and even void your vehic le
warranty. Therefore, proof of servicing in accordance with the main­
tenance schedu le may be a condition for upholding a pos sible
warranty claim made within the warranty period. Above all, operational safety can be adversely affected, creating
unnecessary r isks for you and your passengers .
If in doubt about any servicing, have it done by your authorized Audi
dea ler or any other properly equipped and qualified workshop. We
strongly urge you to give your authorized Audi dealer the opportu­
nity to perform all scheduled maintenance and necessary repairs.
Your dealer has the fac ilities, origina l parts and trained spec ial ists
