Run-flat tires
Ap plies to ve hic les : w it h R un -f la t tires
Introduction
Run-flat tires help keep you moving if a tire goes flat.
Re inforced sidewalls give the tires run -flat capability if t ire pressure
is lost .
We recommend that run -flat tires only be mounted on vehicles that
were origina lly equipped with these special tires at the factory and
have a Tire Pressure Monitoring System.
Run-flat tire s can be identified by the letter s "RSC" on the tire side ­
wa ll.
If you do change the tires on you r vehicle from normal to run -flat
tires , you must buy the special rims required for run -flat tires, and
the Tire Pressure Mon itoring System must be reprogrammed by an
authorized Audi dea ler or other qual ified workshop.
What do run -fl at tires do ?
These specia l tires have run-flat capabilities that help keep you
moving if a tire loses pressure and goes flat. Under favorab le condi -tions tires can be driven
a
t lea st 30 mile s (50 km ), but you must not
drive
fa ster than 50 mph (80 km/h )=> page 259, "Driving with run ­
flat tires".
The Tire Pressure Monitoring System constant ly checks the air pres ­
sure in the tires. If the run-flat system is active (shown in the center
display), you must inspect the affected t ire or t ires and then decide
whether to cont inue dr iving. Be sure to fol low these tips
=> page 259, "Driving with run -flat tir es" .
When it is n ot po ssible to c ontinue dri ving, ev en with
run-flat tir es?
• I f the Electronic Stabi lization Program (ESP) is not work ing o r
keeps coming on.
• I f the Tire Pressure Monitoring System does not work.
• I f the tire has been severely damaged, in a crash, for example .
T he t read can separate from a damaged tire as the wheel turns , and
hit parts of the vehicle, such as the fuel tank filler neck, fuel lines or
brake lines.
• Do not con tin ue d riving if severe vibra tion occurs or if the tire
starts to smoke because the tire is running hot.
• Do not conti nue drivi ng if da mage to the tire, such as cracks in
the sidewal l, appears .
& WARNING
Improper use of run -fl at tires can cause ve hic le da mage th at can
le ad to los s of vehicle control , a crash and seriou s personal injury .
• Run-flat t ires can only be used w ith spe cial rims .
• Run -fl at tires must always be monitored with a properly
programmed Tire Pre ssure Monitoring Sy stem.
• Alway s inspect a tire that ha s lo st air to make sure it i s safe to
drive with the tire in the run -flat mode .
• Never dr ive with run -fl at tire s th at have been dam aged in a
colli sion.

& WARNING (continued)
• 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 specia l 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.
[ i] Tips
• I f you are not able to continue driving with run -flat tires, please
seek professional assistance.
• Please contact your authorized Audi dealer or Audi of America,
Inc . if you have questions about tires and rims. •
Applies to vehic les: with Run-flat t ires
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, particularly 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 or 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.
- Avoid 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.
Please see:=> page 258, "When it is not possible to continue driving,
even with run -flat tires?"
Handling characteristics change when driving with
low air pressure or with flat tires even with special run­
flat tires
A low pressure or flat front tire affects vehicle handling characteris ­
tics by pulling the vehicle slightly to the side where the tire is
mounted and reduces braking performance.
A low pressure or flat rear tire also affects driving characteristics by
pulling to the side where the tire is mounted and also reduces
braking performance. The effect on vehicle handling is most notice ­
able when driving around curves.
& WARNING
Changed vehicle handling characteristics when driving in the run­
flat mode can cause loss of vehicle control, a crash and serious personal injury. .,,,

& WARNING (continued)
• Driving on special run-flat tires in the run-flat mode will change
vehicle handling characteristics during braking, when cornering
and under heavy acceleration .
• Never drive faster than the maximum rated speed of 50 mph
180 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 necessary
weather and road conditions are taken into account .
• Always obey speed limits and other traffic laws.
0 Note
We always recommend driving with even more care when using
these special tires in the run-flat mode. Always avoid sudden
maneuvers. •
Applies t o veh icles: wit h Run -f lat tires
Replacing run -flat tires and rims
Your vehicle was especially designed to use special run­
flat tires.
You may use and combine only approved run-flat tires and special
matching rims that have been designed for run-flat tires. Mounting
special run-flat tires on standard wheels will not work and will not
provide the advantages fo the run-falt feature. Never use special
run-flat tires on standard wheel rims .
After driving with a tire in the run -flat mode , always have the vehicle
and affected tire(sl and rim(s) inspected by an authorized Audi
dealer. Tires that have been driven in the run -flat mode must be
replaced.
& WARNING
Use of damaged run-flat tires and rims can cause vehicle damage
that can lead to loss of vehicle control, a crash and serious
personal injury .
• Always have the vehicle and affected tire(sl and rim(sl
inspected by an authorized Audi dealer after driving a tire in the
run-flat mode.
• Tires that have been driven in the run-flat mode must be
replaced. •

down as far as it will go.
- Close your grip around the
end of the wrench handle for
maximum torque and turn each wheel bolt
clockwise
until it sits tight.
& WARNING
• Using force without control to speed the wheel change up can
cause the vehicle to slip off the jack and cause serious personal
injuries.
• Do not loosen the wheel bolts more than one turn before you
raise the vehicle with the jack. -Risk of injury!
[ i] Tips
• Never try and use the hexagonal socket in the handle of the
screwdriver to loosen or tighten the wheel bolts.
• If a wheel bolt sits very tight, you may find it easier to loosen by
carefully pushing down on the end of the wheel bolt wrench with
one foot only . As you do, hold on to the car to keep yourself stable
and take care not to slip.•

After you ch ange 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 Nm l.
• 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 (continued)
• The engine compartment of any motor vehicle is a potentially
hazardous area. Never reach into the area around or touch the
radiator fan. It is temperature controlled and can switch on
suddenly -even when the engine is off and the ignition key has
been removed. The radiator fan switches on automatically when
the coolant reaches a certain temperature and will continue to run
until the coolant temperature drops .
• Always remove the ignition key before anyone gets under the
vehicle.
• Always support your vehicle with safety stands if it is neces­
sary to work underneath the vehicle. The jack supplied with the
vehicle is not adequate for this purpose and could collapse
causing serious personal injury.
• If you must work underneath the vehicle with the wheels on
the ground, always make sure the vehicle is on level ground, that
the wheels are always securely blocked and that the engine
cannot be started .
• Always make sure the transmission selector lever (automatic
transmission) is in "P" (Park position) (automatic transmission) or
Neutral (manual transmission) and the hand brake is firmly
applied.
<£> For the sake of the environment
• Changing the engine settings will adversely affect emission
levels. This is detrimental to the environment and increases fuel
consumption .
• Always observe environmental regulations when disposing of
old engine oil, used brake fluid, dirty engine coolant, spent batteries
or worn out tires.
• Undeployed airbag modules and pretensioners might be classi ­
fied as Perchlorate Material -special handling may apply, see
