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.

• after the tires have been rotated on the vehicle, or the spare tire
is used,
• if tires with new wheel sensors are used .
A ll pressure warning indicators in the display will be canceled. The
system malfunction error message wil l not disappear until the
vehicle is underway . With pressing the button~
page 256, fig. 154,
the re -programming of the new sensors and storing of ac tua l pres ­
sures starts. This learning phase can take up to 10 minutes driving
time .
During the learning process the tire pressure monitoring system* is
not avai lable. •

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*.
• A whee l change was made but the button

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.

________________________________________________ T_ ir_e _s_ a_n_ d_ w_ h _e_e_ l_s __ lfll
•
& 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. .,,,

Bulbs
Replacing light bulbs
For your safety, we recommend that you have your autho­
rized Audi dealer replace burned out bulbs for you.
It is becoming increasingly more and more difficult to replace
vehicle light bulbs since in many cases , other parts of the car must
first be removed before you are able to get to the bulb. This applies
especially to the light bulbs in the front of your car which you can
only reach through the engine compartment.
Sheet metal and bulb holders can have sharp edges that can cause
serious cuts, and parts must be correctly taken apart and then prop­
erly put back together to help prevent breakage of parts and long
term damage from water that can enter housings that have not been properly resealed.
For your safety , we recommend that you have your authorized Audi
dealer replace any bulbs for you, since your dealer has the proper
tools, the correct bulbs and the expertise.
Gas discharge lamps (Xenon lights)*:
•
Due to the high electrical voltage, have the bulbs replaced by a qual­
ified technician. Headlights with Xenon light can be identified by the
high voltage sticker .
& WARNING
Contact with high-voltage components of the electrical system
and improper replacement of gas discharge (Xenon) headlight
bulbs can cause serious personal injury and death .
• Xenon bulbs are pressurized and can explode when being
changed.
• Changing Xenon lamps requires the special training, instruc ­
tions and equipment .
• Only an authorized Audi dealer or other qualified workshop
should change the bulbs in gas discharge lamps.
& WARNING
There are parts with sharp edges on the openings and on the bulb holders that can cause serious cuts .
• If you are uncertain about what to do, have the work performed
by an authorized Audi dealer or other qualified workshop. Serious
personal injury may result from improperly performed work.
[ i] Tips
• If you must replace the light bulbs yourself, always remember
that the engine compartment of any vehicle is a hazardous area to
work in. Always read and heed all WARNINGS=>
page 209, "Engine
compartment"=>
/A .
• It is best to ask your authorized Audi dealer whenever you need
to change a bulb .•
