lead to loss of vehicle control, a crash and serious personal injury.
• Run-flat tires can only be used with special rims.
• Run -flat tires must always be monitored with a properly
programmed Tire Pressure Monitoring System.
• Always inspect a tire that has lost air to make sure it is safe to
drive with the tire in the run-flat mode .
• Never drive with run-flat tires that have been damaged in a
collision.
• Never drive with run-flat tires if heat build-up causes the tire to
give off smoke.
• Never drive with run-flat tires if the vehicle shakes or vibrates
severely.
• Never drive with a run-flat tire that develops sidewall cracks or
other damage while in use.
0 Note
Run -flat tires have special characteristics and requirements, that are
very different from conventional tires . Run-flat tires require special
rims for run -flat use and cannot be used on conventional wheel
rims .

Inc. if you have questions about tires and rims. •
Applie s t o vehic le s: wi th Run -flat tires
Driving with run-flat tires
Handling characteristics change when tire pressure is
low.
Driving on tires with low tire pressure changes the way a
vehicle handles, particularl y when cornering and braking.
The handling characteristics of run-flat tires do not seem to
change a lot even when driving on low pressure or in the
run -flat mode . Nevertheless you must still take special
precautions when operating a vehicle on run-flat tires when
tire pressure is low o r the tire(s) is flat:
- The Electronic Stabilization Program (ESP) must be
switched on.
- Never drive faster than 50 mph (80 km/h)~ &.
- Plan ahead when driving and anticipate what you will
have to do considering traffic and road conditions up
ahead.
- Accelerate carefully.
- Avo id unnecessary and sudden steering and braking
maneuvers .
- Reduce your speed in plenty of time before intersections,
curves and other places where you may have to react
quickly.

even with run-flat tires?" ..,_

Handling characteristi cs change wh en dri ving with
low air pressure or with flat tires even with special run ­
flat tires
A low pressure or flat front tire affects vehicle hand lin g charac te ri s­
t ics by pulling the vehic le slightly to the side where the tire is
mounted and reduces brak ing performance .
A low pressure or flat
rear tire also affec ts driving c haracteristics by
pul ling to the side where th e tire is mounted and also reduces
b raki ng per for mance . T he ef fec t o n ve hic le han dlin g is most n otice ­
able when driving around curves .
& WARNING
Changed vehicle handling characteristics when driv ing in the run­
flat mode can cause lo ss of vehicle control , a crash and serious
personal injury .
• Driving on special run-flat tires in the run -flat mode will change
vehicle handling characterist ics during braki ng , when cornering
and under heavy acceleration .
• Never drive faster than the max imum rated speed of 50 mph
(80 km /h) when driving in the run -flat mode .
• Always adjust vehicle speed to traffic , road and weather condi­
tions and drive slower than the maximum rated speed if nece ssary
weather and road conditions are taken into ac count .
• Always obey speed limits and other traffic laws .
0 Note
We always recommend driv ing with even more care when using
these special tires in the run -flat mode. A lways avoid sudden

Vehicle care

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.
