& 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. •

Your vehicle is equipped with a t ire repair kit, the Tire Mobility
System (TMSl *.
In the event of a tire fai lure, the TMS is in the luggage compartment
under the floor . It consists of the tire sealant and an e lectric ai r
pump.
Using
TMS , tire damage caused by foreign bodies up to about
0.16 inch (4 mm) in d iam ete r can be sea le d reli abl y.
T he foreign object can stay i n the tire .
The tire sealant mu st not be used :
• for cuts or punctures in the tire which are larger than
0.16 inch
(4 mm )=> page 264, fig . 157 G)
• for damage to the rim@

& WARNING
Take the following precautions after repairing the tire :
• Do not drive faster than 50 mph (80 km/h)!
• Avoid full -throttle acceleration , heavy braking and fast
cornering.
• The vehicle's road behavior can be affected.
• Tires sealed with TMS are intended only for temporary , short­
term use .
• After using the tire sealant the tire pressure monitoring system
may no longer work properly . Drive carefully to the next profes ­
sional repair facility .
• TMS must NOT be used ,
& WARNING (continued )
-for cuts or punctures in the tire which are larger than
0 .16 inch (4 mm)

from moving t raffic.
- Apply the
parking brake firmly.
- On vehicles w ith manual transmission, engage
1st gear,
or move the selector lever to the P position on vehicles
w ith automat ic transmission.
- Check whether a repair using the Tire Mob ility System is
possible ~
page 264, "General and safety po inters".
Have all passengers
leave the vehicle and stay away from
the danger zone~& .
- Take the
sealant bottle and the electric air pump from the
luggage compartment under the floor~ fig. 158. - Remove the "max. 50 mph"
(80 km/h) sticker from the
sealant bottle and affix it to the instrument cluster in the
driver's view.

Re-
inflating tire.
Re-inflating tire
- Remove the hose from the valve and pull the plug out of
the socket.
- Drive the vehicle slowly 10 meters backward or forward.
This helps to distribute the sealant better.
- Remove the empty inflation bottle and screw the hose©
:::;, page 266, fig. 159 from the electric pump directly onto
the valve.

the required tire pressure of at least 1.8 bar has not been
reached, it is not possible to make a repair with the tire
sealant. Seek professional assistance.
Disassembling Tire Mobility System
- Remove the hose from the valve and pull the plug out of
the socket.
- Screw the dust cap onto the valve.
- Place the empty sealant bottle back in the original pack-

-Place the electric air pump in the luggage compartment
for the time being.
- Start driving right away so that the sealant is dist ributed
in the tire.
& WARNING
• Follow the manufacturer's safety instructions on the decal for
the air pump and the sealant bottle.
• If a tire pressure of 1.8 bar cannot be achieved after pumping
for 5 minutes, the tire is too severely damaged. Do not continue to
drive.
• Seek professional assistance if it is not possible to repair the
tire with the tire sealant.
[ i] Tips
• Do not operate the electric air pump for more than 8 minutes
without stopping, otherwise it can overheat. When the air pump has
cooled down, you can continue to use it.
• If sealant has escaped, allow it to dry, then you can peel it off. •

Final check
After driving for a short distance, tire pressure
must be checked
- After driving for about 10 minutes, stop and check the
tire pressure.
- If tire pressure is still at least 1.3 bar, inflate the tire to
specified pressure (see driveas side B-pillarl, drive to the
next repair shop and have the tire and the sealant bottle
replaced. -
If tire pressure is less than 1.3 bar, the tire is too severely
damaged. Do not continue to drive. Seek professional
assistance.
& WARNING
If tire pressure is less than 1.3 bar after driving for 10 minutes, the
tire is too severely damaged. Do not continue to drive. Seek profes­
sional assistance.
[ i] Tips
After a tire repair, have the sealant bottle replaced at a dealership.
This restores full functionality to the Tire Mobility System. •
