Notice about data
recorded by vehicle
control modules
Your vehicle is not equipped with an Event Da­
ta Recorder (EDR), installed by some manu­
facturers fo r the express purpose of capturing
data for retrieval after an accident or crash
event . EDR's are sometimes ca lled "crash re­
corders".
Some state laws restrict the retr ieval or down­
loading of data stored by EDR's that were in­
stalled in a vehicle for the express purpose of
retrieving data after an accident or crash
event without the owner's consent.
A lthough your vehicle is not equipped with an
EDR, it is equipped with a number of electron­
ic control modules for various vehicle systems
such as, for examp le, eng ine function, em is­
sion control, as well as for the airbags and
safety belts.
These electronic contro l modules also record
vehicle-re lated data during normal vehicle op­
eration for diagnostic and repair purposes.
The recording capacity of the electronic con­
trol modules is limited to data (no sound is re­
corded) and only a small amount of data is ac­
tually recorded over a very limited pe riod of
time and stored when a system fault or other
condition is sensed by a control unit. Some of
the data then stored may relate to vehicle
speed, direction, braking as we ll as restraint
system use and performance in the event of a
crash or other condition. Stored data can only
be read and downloaded with special equip­
ment.
Electronic Stabilization
Control (ESC)
Description
ESC helps to improve road holding and vehicle
dynamics to help reduce the probability of
skidd ing and loss of vehicle control. It works
only when the engine is running. ESC detects certain difficult driving situat
ions, including
when the vehicle is beginning to spin (yaw)
out of control and helps you to get the veh icle
back under control by se lectively braking the
wheels, and/or reducing engine power and
providing steering assistance to help hold the
vehicle on the driver's intended course. The in­
dicator light
G) in the instrument cluster
blinks when ESC is taking action to help you
control the vehicle.
ESC has limitations.
It is important to remem­
ber that ESC cannot overcome the laws of
physics. It wi ll not always be able to help out
under all conditions you may come up against.
For example, ESC may not always be able to
help you master situations where there is a
sudden change in the coefficient of friction of
the road surface. When there is a section of
dry road that is suddenly covered with water,
slush or snow, ESC cannot perform the same
way it wou ld on the dry surface . If the vehicle
hydroplanes (rides on a cushion of water in­
stead of the road surface), ESC will not be
able to help you steer the vehicle because con­
tact with the pavement has been interrupted
and the vehicle cannot be braked or steered.
During fast cornering, particularly on winding
roads, ESC cannot always deal as effectively
with difficult driving situations as at lower
speeds.
Always adjust your speed and driving style to
road , traffi<;: and weather conditions. ESC can­
not override the vehicle's physical limits, in­
crease the available tract ion, or keep a vehicle
on the road if road departure is a result of
driver inattention . Instead, ESC improves the
poss ibility of keeping the vehicle under con­
t rol and on the road during extreme maneu­
vers by using the driver's steering inputs to
help keep the vehicle going in the intended di­
rection . If you are traveling at a speed that
causes you to run off the road before ESC can
provide any assistance, you may not experi­
ence the benefits of ESC.
ESC includes and/or works together with the
anti- lock brake system (ABS), brake assist sys-
tem and anti-slip regu lation (ASR). ESC is .,..

overheat reducing the effectiveness of
the ent ire brake system.
- Failure of one brake circuit will impair
the braking capability resulting in an in­
creased stopp ing distance. Avoid driv ing
the vehicle and have it towed to the near­ est Aud i dealer or qualified workshop .
- Never let the vehicle roll to a stop w ith
the engine shut off.
- If the brake booster is not working, for
example when towing your ve hicle, or
because the brake booste r has somehow
been damaged, the brake pedal must be
pressed considerab ly harder to make up
for the lack of booster assistance.
Electro-mechanical
power assist
The electro-mechanical power assist helps
the driver when steering.
The degree of power assist is electronically
matched to vehicle speed.
The power steer ing system ass ists the driver
so that he can stee r the veh icle w ith red uced
phys ica l effort.
Power steering w ill not work if the engine is
off. As a result, the steering wheel w ill be hard
to turn.
& WARNING
If the system develops a prob lem, you
must seek qualified professional assis­
tance.
(D Note
-
If there is an electronic malfunct ion, ser­
votronic
wi ll sti ll function like a conven­
tional power steering system, providing a
constant steering support force that is no
longer proportionate to the vehicle speed.
This is most noticeable when turning the
steer ing wheel at low speeds (for example
when parking), -more effort will be re­
quired than usual.
Int ellig ent technolog y 155
-Be aware of the different than usual
steering response and adjust your steer­
ing force accordingly.
- Have the problem checked and set right
by an authorized Audi dea ler as soon as
possible.
- If a steering malfunction occurs, this is
signaled with the,~ , or .• indicator
lights and a warn ing tone, see.
(D Tips
- If the power steering system sho uld fail,
or if the engine is not running (for exam­
ple, while being towed), you will still be
able to steer the vehicle. However, more
effort will be required to do so.
- If the power steering system is not func­
tioning properly, contact your authorized
Audi dealer immediately.

General information
With a ll-wheel drive, power is distr ibuted to
all four wheels. This happens automatically
depend ing on your driving style and the road
conditions at the time. See also
c::> page 1 SO.
The all-whee l dr ive concept is des igned for
high eng ine power. Your veh icle is except ion­
ally powerfu l and has excellent driving charac­
teristics both under normal driving conditions
and on snow and ice. Always read and follow
safety precautions
c::> &. .
Winter tires
When dr iving in the winter, your vehicle with
all-wheel drive has an advantage, even with
regular tires. In winter road conditions it may
be advisable to mount winter tires (or all-sea­
son tires) for improved driveability and brak­
ing: these tires must be mounted on
all fou r
wheels. See also c::> page 211, Winter tires. ..,_

-Never mount used tires on yo ur vehicle if
yo u are not sure of their "previous histo­
ry." Old used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden tire failure
and loss of vehicle control.
- If you notice unusual vibration or if the
vehicle pulls to one side when d riving, al­
ways stop as soon as it is safe to do so
and check the wheels and tires for dam­
age .

206 Tires and wheels
Tire service life
The service life of tires depends on a lot of
different things including proper installation
and balancing, correct tire pressure and driv­
ing style.

Fig. 145 Rotating t ires for more ev en wea r
Tread Wear Indicator (TWI)
The original tires on your vehicle have
1/16 inch (1.6 mm) high "wear indicators"
c::> fig . 144 running across the tread. Depend­
i ng on the make, there will be six to eight of
them evenly p laced around the tire. Marks on
the tire sidewa ll (for example "TWI" or other
symbols) indicate the positions of the tread
wear ind icators . Worn t ires must be replaced .
Different figures may apply in other countries
c::> & .
Tire pressure
Incorrect tire pressure causes premature wear
and can cause sudden t ire blow-out. For th is
reason, tire pressure must be checked at least
once a month
c::> page 202 .
Driving style
Driving fast around curves, heavy acceleration
and hard braking increase tire wear.
Rotating tires for more even wear
For all four tires on your vehicle to have the
same service life, we recommend that the
front and rear tires are rotated according to
the tire manufacturer's suggested tire rota­
tion intervals. Please remember the follow­
ing :
- Tire rotation intervals may differ from the
vehicle service interva ls outlined in your
Warranty
& Maintenance Booklet.
- The longer one tire is used in one location
on the vehicle, the more it wears at certain
points; therefore, we recommend that you
follow the tire manufacturer's suggested
tire rotation intervals .
- Vehicles with front-wheel drive experience
more tread wear on the front wheels com­
pa red to all-wheel drive (quattro ®).
- Please rotate tires as shown
c::> fig. 145.
-Extra care must be taken when rotating di-
rection-specific tires
c::> page 22 7 .
Wheel balancing
The wheels on new vehicles are balanced.
However, various situations during everyday
driving can cause them to become unbal ­
anced, re sulting in vibrat ions you can usually
feel through the steer ing wheel.
Unbalanced wheels must be rebalanced to
avoid excessive wear on steering, suspension
and tires. A whee l must also be rebalanced
when a new tire is installed.
Incorrect wheel alignment
Incorrect wheel alignment can cause exces ­
sive tire wear, impairing the safety of the veh i­
cle. If tires show excessive wear, have the
whee l alignment checked by an authori zed
Audi dealer or qualif ied workshop.
all-wheel drive
Vehicles with quattro ® mus t always have tires
of the same size, construction and tread type .

218 Tires and wheels
When it is not possible to continue
driving , even with run-flat tires?
-If the E lectronic Stabilization Control (ESC)
is not working or keeps coming on.
- If the
Tire Pr essure Monitoring System does
not work .
- If the tire has been severely damaged, in a
crash , for example. The tread 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 continue driving if severe vibration occurs or if the tire starts to smoke because
the tire is running hot.
- Do not continue driving if damage to the
tire, such as cracks in the sidewall, appears.
A WARNING
Improper use of run-flat tires can cause
vehicle damage that can lead to loss of ve­
hicle control, a crash and serious personal
lnJUry.
- Run-flat tires can only be used with spe­
cial rims.
- Run-flat tires must always be mon itored
with a properly programmed Tire Pre­
ssu re Monit oring Sys tem.
- Always inspect a tire that has lost air to
make sure it is safe to drive with the tir e
in the run-flat mode.
- Never drive with run-flat tires that have
been damaged in a collision.
- 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 vehi­
cle shakes or vibrates severely.
- Never drive with a run-flat tire that de­
velops sidewall cracks or other damage
wh ile in use .
-If you switch between standard and run­
flat tires, an authorized Audi dealer or
qualified workshop must reprogram the
control module.
(D Note
Run-flat tires have specia l characteristics
and requirements, that are very different
from conventional tires. Run-flat tires re­
quire special rims for run-flat use and can­
not be used on conventional wheel rims.
(D Tips
- If you are not able to cont inue driv ing
w ith run-flat tires, please seek professio­
nal assistance.
- Please contact your authorized Audi
dealer or Audi of America, Inc. if you
have questions about tires and rims .
Driving with run-flat tires
Applies to vehicles: wit h Run -flat tires
Handling characteristics change when tire
pressure is low .
Driving on tires with low tire pressure changes
the way a veh icle handles, particularly when
cornering and braking. The handling charac­
teristics of run-flat tires do not seem to
change a lot even when driving on low pres­
sure or in the run-flat mode . Nevertheless you
must still take spec ia l precautions when oper­
at ing a vehicle on run-flat tires when tire pres­
sure is low o r the tire(s) is flat:
.,. Th e Electronic Stabilization Control (ESC)
must be switched on.
.,. Never drive faster than SO mph (80 km/h)
q &_ .
.,. Plan ahead when driving and anticipate
what you will have to do considering traffic
and road conditions up ahead .
.,. Accelerate carefully.
.,. Avo id unnecessary and sudden steering and
brak ing maneuvers .
.,. Reduce your speed in plenty of time before
intersections, curves and other places where
you may have to react qu ickly.

ble to continue driving, even with run-flat
tires?
