• The battery inside of the tire pressure sensor has a limited

recommend using factory insta lled valve stem caps . Ask your au tho ­
rized Audi dealer to replace lost va lve stem cap s.

& 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 spe cifically 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 .
• Never mount used tires on your vehi cle 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 vehi cle control.
& WARNING (continued)
• All four wheels must be fitted with radial tires of the same type,
size (rolling circumference ) and the same tread pattern. Driving
with different tires reduces 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 e xample with winter tires -only use the spare
tire for a short period of time and drive with extra care . Refit the
normal road wheel as soon as safely possible.
• Never drive faster than the maximum speed for which the tires
on your vehicle are rated because tires that are driven faste r than
their rated speed can fail suddenly .
• Overloading tires cause heat build-up , sudden tire failure ,
including 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 chnical reasons it is not always possible 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 blocked. Redu ced airflow to
the brakes can them to overheat , increasing 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 must have a chassis designed
for run flat tires and a factory -installed tire pressure monitoring
system that indi cate s a loss of tire pressure . Incorre ct use of run
flat tires can lead to vehicle damage or accidents . Check with an
authorized Audi dealer o r tire specialist to see if your vehicle can
be equipped with run flat tires .
If run flat tires are used, they must
be installed on all four wheels . Mixing tire types is not permitted. .,

What do I do now? -
----------------
•
-Screw the threaded end of the alignment pin from the
tool kit hand-tight into the now vacant bolt hole
=:> page 270, fig. 177.
- Then completely unscrew the other wheel bolts as
described above.
- Take off the wheel leaving the alignment pin in the bolt
hole.
Putting on the 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.
- Unscrew 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 268. Tighten them crosswise, from one
bolt to the (approximately) opposite one, to keep the
wheel centered.
[ i J 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 272.
• 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
wheel. •
Notes on wheel change
Please read the information~ page 249, "New tires and replacing
tires and wheels", if you are going to use a spare tire which is
different from the tires on your vehicle.
After you change a tire:
• Check the tire pressure on the spare immediately after
mounting.
• Have the wheel bolt tightening torque checked with a torque
wrench as soon as possible by your authorized Audi dealer or a qualified service station .
• With steel and alloy wheel rims, the wheel bolts are correctly
tightened at a torque of 90 ft lb (120 Nml.
• If you notice while changing a tire that the wheel bolts are
corroded and difficult to turn, then they should be replaced before
you check the tightening torque.
• Replace the flat tire with a new one and have it installed on your
vehicle as soon as possible. Remount the wheel cover.
Until then, drive with extra care and at reduced speeds.
& WARNING
• If you are going to equip your vehicle with tires or rims which
differ from those which were factory installed, then be sure to read
the information
~ page 249, "New tires and replacing tires and
wheels".
• Always store the tools securely in luggage compartment.
Otherwise, in an accident or sudden maneuver they could fly
forward, causing injury to passengers in the vehicle.
