Notice about data
recorded by vehicle
control modules
Your veh icle is not equipped with an Event Da­
ta Recorde r (EDR), ins talled by some manu­
facture rs fo r the express p urpose of capturing
data for retrieval after an accident or cras h
event . EDR's are sometimes ca lled "crash re­
corders".
Some state laws restr ict 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 ltho ugh yo ur vehicle is not equ ipped wit h an
EDR, it is equipped with a number of electron­
ic control modules for various vehicle systems
such as, for examp le, eng ine f unction, 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 norma l vehicle op­
erat ion for diagnostic and repa ir 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 ove r a ve ry limited pe riod of
time and stored when a sys tem faul t or o ther
cond ition is sensed by a cont ro l u nit. Some of
the data then stored may re late to vehicle
speed, direction, braking as we ll as restraint
system use and performance in the event of a
crash or other condit ion. Stored data can only
be read and downloaded w ith 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 ve hicle control. It works
only when the eng ine is running. ESC detects certain difficult driving situat
ions, including
when the vehicle is beginning to spin (yaw)
o ut of control and he lps you to get the veh icle
back under control by se lectively braking the
whee ls, and/or reducing eng ine power and
providing steer ing ass istance to he lp hold the
vehicle o n the dr iver's intended course. The in­
dicator light
G) in the inst rument cluster
blinks when ESC is ta king action to help yo u
control the veh icle.
ESC has limitations.
It is importa nt to remem­
ber that ESC cannot overcome the laws of
physics. It wi ll not always be able to help out
under a ll cond it ions you may come up aga inst.
F or example, ESC may not always be able to
help you master situations where there is a
s u dden change in the coefficient of friction of
the road surface. When there is a section of
dry road that is sudden ly covered w ith water,
s lush or snow, ESC cannot perform the same
way it wou ld on the dry surface . If the ve hicle
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 in terrupted
and the vehicle cannot be braked or steered .
D uring fast cornering, particularly on winding
roads, ESC cannot always deal as effectively
with difficult driving situations than at lower
speeds. When towing a trailer, ESC is not able
to help you regain control as it would if you
were not tow ing a trailer.
Always adjust your speed and driving style to road, traffic; and weather condit ions. ESC can­
not override the vehicle's physical limits, in­
crease the availab le tract ion, or keep a ve hicle
on the road if road departure is a result of
drive r inattent io n. Instead, ESC imp roves the
poss ibil ity of keeping the vehi cle under con ­
trol and on the road during ex treme maneu­
vers by using the d river's steering inputs to
help keep the vehicle going in the intended di­
rection . If you are traveling at a speed that
ca uses you to run off the road before ESC can
provide any assistance, you may not experi­
ence the benefits of ESC.

196 Intellig ent technolog y
-Never let the vehicle roll to a stop with
the engine shut off.
- If the brake booster is not working, for
example when towing your vehicle, or
because the brake booster has somehow
been damaged, the brake pedal must be
pressed considerably harder to make up
for the lack of booster assistance .
Electro-mechanical
power assist
The electro-mechanical power assist helps
the driver when steering.
Power stee ring adapts electronically based on
the veh icle speed.
Indicator lights and messages
• Steerin g d efecti ve! Stop th e vehicl e
If this indicator light turns on and stays on
and this message appears, the power steering may have fa iled.
Do
not continue driving . See your authorized
Aud i dealer or other qualified repa ir facility
for assistance.
lor-ij St eerin g: S yste m malfun ction ! You m ay
c ont inue driv ing
If the indicator light turns on and the mes ­
sage appears, the steering may be more diffi­
cult to move or more sensitive than usual.
Drive s low ly to your author ized Audi dealer or
q ua lified workshop to have the malfunction
corrected .
(D Tips
If the . or 'Iij indicator light only stays
on for a shor t time, you may contin ue driv­
ing .
Driving with your
quattro ®
Applies to vehicles : with all-wheel drive
With all-wheel drive , all four wheels are driv­
en .
General info rmation
With a ll Wheel Drive, power is distributed to
all four wheels. This happens automatically
depending on your driving style and the road
condit ions at the time. See also ¢
page 192.
With the sport differential*, power distribu­
t ion to the rear wheels is va riable and can be
adjusted with Audi drive select*
r::¢, page 98.
Always read and follow safety precautions
Q _& .
Winter tires
When driving in the winter, your vehicle with
all-wheel drive has an advantage, eve n wit h
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 mo unted on
all fou r
wheel s. See also ¢ page 255 , Winter tires.
Tire chains
Where tire chains are mandatory on certain
roads, this no rma lly also app lies to ve hicles
with all-wheel drive r::¢,
page 256, Snow
chains.
Replacing wh eels /tires
Vehicles with all-wheel drive m ust always
have ti res of the same s ize. A lso avo id tires
with different t read depths . For detai ls see
page r::¢,
page 251, New tires and replacing
tires and wheels .
Off-Road driving?
You r Audi does not have e nough ground clea r­
ance to be used as an off-road vehicle . It is
t h erefore best to avoid rough tracks and un ­
even terrain as much as possib le . Also refer to
r::¢, page 200. ..,_

-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 .
(D Note
Please note that summe r and wi nte r tires
are designed for the cond itions that are
Glossary of tire and loading terminology
Accessory weight means the comb ined weight (in excess of
those sta ndard items which may be rep laced)
of au toma tic transmission, power steer ing ,
power brakes, power windows, power seats,
radio, and heater, to the extent that these
items are availab le as factory-installed equip­
ment (whether installed or not) .
Aspect ratio
means the rat io o f the height to the w idth of
the tire in percent . Numbers of 55 or lower in ­
dicate a low sidewall for improved steering re­
sponse and better overa ll handling on dry
pavement .
Bead
means the part of the t ire t hat is made o f
steel wires, wrapped or reinforced by ply cords
and that is shaped to fit the r im.
Bead separation
means a b reakdown of the bond between
components in the bead .
Cord means the strands forming the plies in the
tire.
Tire s an d wheel s 241
typica l in those seasons . Aud i recommends
using winter tires during the winter
months . Low temperatures signif icant ly
dec rease the e lasticity of summer t ires,
which affects tract ion and brak ing ability.
If summer t ires are used i n very co ld tem ­
peratures, cracks ca n form o n the tread
bars , res ulting in perma nen t tire damage
that can cause loud driving noise and un­
bala nced ti re s. Audi i s not respon sible for
th is type of damage .
Cold tire inflation pressure
means the t ire p ress ure recommended by t he
vehicle manufacture r fo r a tire o f a des ignated
s ize t hat has not bee n driven for more than a
coup le o f miles (k ilometers) at low speeds in
the three hour period before the tire press ure
is m easured or adjusted.
Curb weight
me ans the we ight of a motor ve hicle with
st andard equipmen t incl ud ing the max imum
capacity of fuel, oi l, and coolant, air condi ­
tioning and additional weig ht of optiona l
equipment.
Extra load tire
means a t ire design to oper ate a t higher load s
and at higher inflation pressures than the cor­
responding standa rd tire . Extra load tires may
be identified as "XL", "x l", "EXTRA LOAD", o r
"RF" on the sidewal l.
Gross Axle Weight Rating ("GAWR")
me ans the load-ca rry ing capac ity of a single
axle system , measured at the tire -ground in­
te rfaces.
Gross Vehicle Weight Rating ( "GVWR ")
mea ns the maximum total loaded we ight of
