•
• T he battery inside of the tire pressure sensor has a limited
service life.
• Always drive with the va lve stem caps securely mounted. We
recommend using fac tory insta lled valve stem caps . Ask your autho­
rized Audi dealer to replace lost valve stem caps .
T he 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 info rmation
i n molded on the t ire sidewa ll).
A lways check your tire pressure monitoring system * indicator after
replac ing one or more tires on you r veh ic le . If t he tir e pressure
monitoring system * indicator f lashes, or is on, your system is not
wo rking pr ope rly. Your re place ment tire might be i nco m patible wit h
your tire pr essure monitoring system *, or some component of the
t ir e pr ess ure moni toring system * m ay be da maged.
& WARNING
• Using incorrect or unmatched tires and / or wheels or improper
tire and wheel combinations can lead to los s of control , collision
and serious personal injury .
• Alway s use tires , rims and wheel bolts that meet the specifica ­
tions of original fa ctory -installed tires or other combination s that
have been specifically approved by the vehi cle manufacturer .
• Tires age even if they are not being used and can fail suddenly,
espe cially at high speeds . Tire s that a re more than 6 years old can
only be used in an emergency and then with special care and at
lo wer speeds .
• Never mount used tire s on your vehicle if you are not sure of
their "previous history ." Old used tires may have been dam aged
even though the damage cannot be seen that can lead to sudden
ti re failure and lo ss of vehicle control.
• All four wheels must be fitted with radial tires of the same type ,
size (rolling cir cumference ) and the same tread pattern . Driving
& W ARNING (continued )
with different tires redu ces vehicle handling and can lead to a loss
of control.
• If the spare tire is not the same as the tires that are mounted
on the vehicle -for example with winter tires -only use the spare
tire for a short period of time and dri ve with extra care . Refit the
normal road wheel as soon a s safely pos sible.
• Never drive faster than the ma ximum speed for which the tires
on your vehicle are rated because tires that are driven faster than
their rated speed can fail suddenly .
• Overloading tires cause heat build -up , su dden tire failure ,
includ ing a blowout and sudden deflation and loss of control.
• Temperature grades apply to tires that are properly inflated and
not over or underinflated .
• For te chni cal reasons it is not always po ssible to use wheels
from other vehicles -in some cases not even wheels from the
same vehicle model.
• If you install wheel trim discs on the vehicle wheels , make sure
that the air flow to the brakes is not blo cked . Redu ced airflow to
the brake s can them to overheat , increa sing stopping distances
and causing a collision.
• Run flat tires may only be used on vehicles that were equipped
with them at the fa ctory . The vehicle mu st have a cha ssi s designed
for run flat tires and a factory -installed tire pressure monitoring
s ystem* that indicates a lo ss of tire pressure . Incorrect use of run
flat tires can lead to vehicle damage or accident s. Check with an
authorized Audi dealer or tire specialist to see if your vehicle can
be equipped with run fl at tires . If run flat tires are used , they must
be installed on all four wheels . Mi xing tire types is not permitted.

• Fo r techn ica l reaso ns, i t is no t genera lly p oss ibl e to use the
whee l rims from other vehicles . T his can hold true for wheels of the
sa me vehicle type. ..,.

Taking the wheel off/installing the spare
Follow these instructions step-by-step for changing the
wheel
Fig . 291 Changing a
wheel: using the
screwdriver handle
!with the blade
removed) to turn the
bolts
Fig . 292 Changing a
wheel: alignment pin
inside the top hole
After you have loosened all wheel bolts and raised the
vehicle off the ground, remove and replace the wheel as
follows:
Removing the wheel
-Use the hexagonal socket in the screwdriver handle to
completely remove the topmost wheel bolt and set it
aside on a
clean surface => fig. 291. -
Screw the threaded end of the
alignment pin from the
tool kit hand-tight into the empty bolt hole=> fig. 292.
- Then remove the other wheel bolts as described above .
- Take off the wheel leaving the alignment pin in the bolt
hole.
Putting on the spare wheel
- Lift the spare wheel and carefully slide it over the align­
ment pin to guide it in place.
- Use the hexagonal socket in the screwdriver handle to
screw in and tighten all wheel bolts
slightly.
- Remove the alignment pin and insert and tighten the
remaining wheel bolt slightly like the rest.
Turn the jack handle counter-clockwise to lower the
vehicle until the jack is fully released.
- Use the wheel bolt wrench to tighten all wheel bolts
firmly=>
page 356. Tighten them crosswise, from one
bolt to the (approximately) opposite one, to keep the
wheel centered.
[ i ] Tips
Never use the hexagonal socket in the handle of the screwdriver to
loosen or tighten the wheel bolts.
• Pull the reversible blade from the screwdriver before you use the
hexagonal socket in the handle to turn the wheel bolts.
• When mounting tires with
unidirectional tread design make sure
the tread pattern is pointed the right way=>
page 359.
• The wheel bolts should be clean and easy to turn. Check for dirt
and corrosion on the mating surfaces of both the wheel and the .,,_

hub. Remove all dirt from these surfaces before remounting the
whee l.•
Tires with unidirectional tread design
Tires with unidirectional tread design must be mounted
with their tread pa ttern pointed in the ri ght direction.
Using a spar e tire with a tread pattern intended for u se
in a sp ecific di rec tion
When using a spare tire with a tread pattern intended fo r use in a
specific direction, p lease note the following:
• The direction of rotation is ma rked by an arrow on the side of the
tire .
• I f the spare tire has to be insta lled in the incorrect direction, use
the spare tire only temporarily since the tire wi ll not be able to
achieve its optimum performance characteristics with regard to
aquaplaning, noise and wear.
• We recommend that you pay particular attention to this fact
during wet weather and that you adjust you r speed to match road
conditions .
• Replace the flat tire with a new one and have it installed on your
veh ic le as soon as possible to restore the handling advantages of a
un idirectional tire. •
Notes on wheel changing

tion . • Have the wheel bolt t
ighten ing torque che cked with a torque
wrench as soon as possible by your authorized Audi dealer or a qualified service station .
• With steel and alloy wheel rim s, the wheel bolts are correctly
tighte ned at a torque of 90 ft lb (120 Nm ).
• If you noti ce that the wheel bolt s are corroded and difficult to
turn while changing a ti re , they should be replaced before you che ck
the tightening torque .
