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

• 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

& 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. •

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. •

Fuses and bulbs -
------------------
The various electrical circuits are protected by fuses. The fuses are
clustered in a centralized unit. The unit is located behind the face
panel at the end of the instrument panel.
Two spare fuses and a sticker identifying the fuses are located on
the inside of the fuse box cover.
You are well advised to keep a supply of spare fuses in your vehicle.
Fuses with the proper ampere ratings are available at your autho­
rized Audi dealer.
& WARNING
Never replace a fuse with one that has a higher amperage rating .
• A fuse with a too high amperage could damage the electrical
part and cause a fire.
0 Note
• On no account should fuses be repaired (e.g. patched up with tin
foil or wire) as this may cause serious damage elsewhere in the elec­
trical circuit or cause fire.
• If a fuse blows repeatedly, do not keep replacing it. Instead, have
the cause for the repeated short circuit or overload tracked and
fixed. •
