2009 AUDI TT COUPE Owners Manual

Tires and wheels -
----------------
•
& WARNING (continued)
• Do not adjust tire pressure when tire temperature is excessive.
This could lead to serious tire damage and even cause the tire to
burst, with the additional danger of an accident.
Driving with under -inflated tires reduces fuel efficiency and tire
tread life.
[ i] Tips
• Each tire should be checked monthly when the temperature of
the tires is about the same as ambient air temperature and set to the
recommended inflation pressure as specified on the tire pressure
label =>
page 238.
• The factory supplied spare wheel is equipped with a sensor for
the tire pressure monitoring system *. As long as the spare wheel is
not mounted, the tire pressure of this tire will not be monitored.
• The tire pressure monitoring system * helps the driver to keep an
eye on tire pressures. But the driver still has the responsibility for
maintaining the correct tire pressure.
• Tire pressure must only be adjusted when the temperature of the
tires is about the same as ambient air temperature.
• When tires are replaced, the sensors and valves should not be
exchanged . The valve core, nut, valve sealing and seal washer
(replacement kit) needs to be replaced. If necessary, the valve and
the wheel electronics have to be replaced.
• If you should put different wheels and tires on your vehicle (e.g.
winter wheels and tires), you must be certain that the wheels and
tires are compatible with the tire pressure monitoring system*.
Otherwise the system will register a malfunction and a fault
message will be displayed. For more information, contact your Audi
dealer. •
Adjust the tire pressure and store the pressure in the tire pres­
sure monitoring system* to the load you are carrying.

page 72 , fig. 2@ .
[ i) Tips
• In the case of an intentional loss of air pressure, for example,
when re -adjusting tire pressure, this has to be stored again after ­
wards=>
page 256.
• Tire pressure must only be adjusted when the temperature of the
tires is about the same as ambient air tempera ture.
• The yellow symbol disappears, when the tire pressure is
correc ted and the new pressure is stored in the system=>
page 256.
• After changing a wheel or replacing a wheel with the spare tire
you have to adjust the tire pressures on all wheels. In addition , you
must then initialize the new tire pressures in the tire pressure moni ­
toring system*=>
page 257. •

Storing tire pressures
Correct storage of specified pressure is the basic require ­
ment for reliable tire pressure monitoring.
Fig. 154 SET-button :
Tire pressure moni­
toring system
In order for the tire pressure monitoring system* to operate
appropriately, you have to re-save the specified pressures
whenever you adjust tire pressures, for example when the
load condition of your vehicle changes . Proceed as follows:
Correcting tire pressure
Check the pressure in the tires.
Adjust air pressure as needed to comply with the infor­ mation on the label located on the driver's side B -pillar
(vis ible when the door is open).
Saving tire pressures
Turn on the ignition.
Press the button=> fig. 154 for app roximately 5 seconds.
You will hear a beep and the symbol in the instrument
cluster flashes three times.
All pressure warning indicators in the display will be canceled.
Following each intentional change in specified pressures, tire pres­
sures must be resaved.
After the pressures are saved, the tire pressure monitoring system* measures the current tire pressures and saves them as the new
specified pressures.
[ i J Tips
• The tire pressure is shown on the tire pressure label. The tire
pressure label is located on the driver's side B-pillar (visible when
the door is open). The tire pressure label lists the recommended cold tire inflation pressures for the vehicle at its maximum capacity
weight and the tires that were on your vehicle at the time it was
manufactured . For recommended tire pressures for normal load
conditions, please see chapter
=> page 238. .,_

tire pressure mon itoring system* is not available. This can have
various causes.
• If the message appears at the end of the lear ning process, the
system cannot recognize the wheels installed on the vehicle. This
can be because one or more wheels without a wheel sensor were
insta lled.
• A wheel sensor or other component may have failed .
• During initialization the system has detected more than 4 wheels
on the vehicle, for example whi le driving next to another car with a
tire pressure monitoring system*.

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. •

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. •
