pressure, even if under-inflation has not reached the level to trigger
illumination of the TPMS low tire pressure tellta le .
Your vehicle has also been equipped with a TPMS malfunction indi­ cator to indicate when the system is not operating properly . The
TPMS malfunction indicator is combined with the low t ire pressure
telltale . When the system detects a ma lfunction, the telltale wil l
fl ash for approximately one minu te and then remain continuously
illuminated . T his sequence will continue upon subsequent vehicle
start-ups as long as the ma lfunction exists.
When the malfunction indicator is illuminated, the system may not be ab le to detect or signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of reasons, including the
installation of replacement or alternate tires or wheels on the
veh icle that prevent the TPMS from functioning properly. Always
check the TPMS malfunction telltale after replacing one or more
tires or whee ls on your vehicle to ensure that the replacement or
a lternate tires and wheels allow the TPMS to continue to function
properly .•
Introduction
The tire pressure monitoring system monitors air pressure
in all four road wheels while the vehicle is moving.
As soon as the tire pressure mon itoring system senses a s ignificant
loss of air pressure in one or severa l tires, text messages and yellow
symbo ls appear in the instrument cluster display to a lert the driver .
T he ~ warning light in the instrument cluster comes on when the
t ire is significant ly underinflated ;;:,
page 20.
The warning light ' also illuminates in the case of a system
malfunction.
Be aware that tire pressure is also dependent on the temperature of
the tire. For every 18 °F (10 °Cl increase in tire temperature, tire pres ­
sure increases by about 1 .5 psi (0 .1 bar). The tire warms up while the
vehic le is moving and tire pressure rises. So you should adjust tire

pressure only when they are cold, when the temperature of the tires
is roughly the same as the ambien t air temperature .
In order to keep the tire pressure monitoring system properly cali ­
brated, tire pressure on all four tires should be checked at regular
intervals, adjusted if necessary and saved in the proper setting
(recommended pressure) ;;:,
page 45.
The tire pressure is shown on the tire pressure label. On USA vehi­
cles, the tire pressure labe l is located on the driver's side 8-pi llar . On
Canada vehicles, the tire pressure labe l is located eithe r on the
driver's side 8 -p illar or inside the fuel fi ller flap. The tire pressure
label lists the recommended cold tire inflation p ressu res for the
vehic le 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 351.
& WARNING
• When the tire pre ssure monitoring sy stem warning light i s lit ,
one o r mor e of your tires i s signifi ca ntl y under -infl ated . You should
stop and che ck your tire s as soon as possible , and inflate th em to
th e prop er pre ssure a s indicated on the v ehicle' s tir e pr ess ure
l a bel ;;:,
pa ge 351. Driving on a signifi cant ly under-infl ated tire
ca use s the tire to overhe at and can lead t o tire f ailure. Und er-infla ­
tio n a lso is likely to imp air th e vehicle' s handling and stoppi ng
ability .
• Do not adju st tire pre ssure whe n tire temp erature is exc essiv e.
Thi s could le ad to serious tire damage and even cause the ti re to
burst , with the additi onal d ange r of an acc ident .
Driving with under -inflated tires reduces fue l efficiency and tire
tread life.

[ i ] Tip s
• 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 45 .
• Tire pressure must only be adjusted when the temperature of the
tires is about the same as ambient air temperature.
• The ye llow symbol disappears, when the tire pressure is
corrected and the new pressure is stored in the system=:>
page 45.
• After changing a wheel you have to adjust the tire pressures on
all whee ls . In addition, you must then initialize the new tire pres­
sures in the tire pressure monitoring system=:>
page 46. •
Storing tire pressures
Correct storage of specified pressure is the basic require­
ment for reliable tire pressure monitoring.

• Your vehicle warranty does not cover any damages to the vehicle
caused by using roof racks or moun ting structures no t approved by
Audi for your vehicle . T he same app lies to damage resulting from
incorrect roof rack installation .
• Always check the roof rack mountings and hardware before each
t rip and during a trip to make sure everything is securely tightened.
If necessary, retighten the mountings and check the entire system
from time to time.
• After mounting a roof rack system, or when you transport
objects on the roof of your vehicle, the height of the vehicle is natu­
ra lly increased . Be carefu l when driving under low bridges or in
parking garages for exa mple . This cou ld cause damage to the load
and even the vehicle itself .•

• Always use suitable mounting straps for securing items to the
roof rack to help prevent items from shifting or flying forward .
• Items on the roof rack must always be securely mounted .
• The use of a roof rack can negatively affect the way a vehicle
handles. Cargo that is large, heavy , bulky, long or flat will have a
greater negative influence on the vehicle's aerodynamics , center
of gravity and overall handling . Always drive slowly, avoid sudden
braking and maneuvers when t ransporting cargo on the roof of
your vehicle.
• Never exceed the maximum permissible load carrying capacity
of the roof of your vehicle , the permissible axle weights and the

Intelligent technology
Notice about data recorded by
vehicle control modu les
Your vehicle is not equipped with an Event Data Recorder (EDR),
installed by some manufacturers for the express purpose of
capturing data for retrieval after an accident or crash event . EDR's
are sometimes called "crash recorders" .
Some state laws restrict the retrieva l or downloading of data stored
by EDR's that were insta lled in a vehicle for the express purpose of
retrieving data after an accident or crash event without the owner's
consent.
Although your vehicle is not equipped with an EDR, it is equipped
with a number of electronic control modules for various vehicle systems such as, for example, engine function, emission control, as
well as for the airbags and safety belts.
These electronic control modules also record vehicle-related data during norma l vehicle operation for diagnost ic and repair purposes .
The recording capacity of the electronic control modules is limited
to data (no sound is recorded) and only a small amount of data is
actually recorded over a very limited period 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 well as restraint system use and performance in the
event of a crash or other condition . Stored data can only be read and
down loaded with special equipment .•
Electron ic Stabilizat ion Program (ESP)
General =nformation
The ESP improves the vehicle stability.
Fi g. 2 75 C ente r
co nso le w it h ES P
swi tch
ESP is designed to he lp you maintain vehic le control in situations
where the car approaches the limits of "grip", especia lly when
accelerating and cornering. ESP reduces the risk of skidding and
improves stabil ity under all road conditions .
T he system operates across the entire speed range in combination
with the ABS system. If the Anti-Lock Brake System (ABS) malfunc­
tions, the ESP wil l also shut down .
How th e sys te m w ork s
The Anti -Lock Brake System (ABS) , Electronic Differential Lock (EDU
and the Anti-Slip Regulation System (ASR) are integrated in the e lec­
tronic stabi lization program . In addition to the data provided by
these functions, the ESP control unit requires additional measure­ ment data provided by high performance sensors . The rotational
speed of the vehic le about its vertical axis, vehicle acce leration in
the fore-and-aft and lateral directions, the brake pressure and the steering angle are al l measured .

& WARNING (continued)
crashes and serious personal injuries . Have worn or damaged tires
replaced immediately.
• Tires age even if they are not being used and can fail suddenly,
especially at high speeds. Tires that are more than 6 years old can
only be used in an emergency and then with special care and at
low speed.
Glossary of tire and loading terminology
Accessory weight
means the combined weight (in excess of those standard items
which may be replaced) of automatic transmission, power steering,
power brakes, power windows, power seats, radio, and heater, to
the extent that these items are available as factory-installed equip­

& WARNING (continued)
• Never mount used tires on your vehicle if you are not sure of
their "previous history." Old used tires may have been damaged
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 driving, always stop as soon as it is safe to do so and check
the wheels and tires for damage . •
Cold tire inflation pressure
means the tire pressure recommended by the vehicle manufacturer
for a tire of a designated size that has not been driven for more than
a couple of miles (kilometers) at low speeds in the three hour period
before the tire pressure is measured or adjusted.
Curb weight means the weight of a motor vehicle with standard equipment
including the maximum capacity of fuel, oil, and coolant, air condi­
tioning and additional weight of optional equipment.
Extra load tire
means a tire design to operate at higher loads and at higher infla ­
tion pressures than the corresponding standard tire. Extra load tires
may be identified as "XL",

Uniform Tire Quality Grading
is a tire information system developed by the United States National
Highway Traffic Safety Adm inistration (NHTSA) that is designed to
help buyers make relative comparisons among tires. The UTQG is
not a safety rati ng and not a guarantee that a tire will last for a
prescribed number of miles (kilometers) or perform in a certain way.
It simply gives tire buyers additional informat ion to combine with
other considerations, such as price, brand loyalty and dealer recom-mendations. Under UTQG, tires are graded by the tire manufac­
t urers in three areas: treadwear, traction, and temperature resis­
tance . The UTQG information on the tires, molded into the
sidewalls.
U .S. DOT Tire Identification Number (TIN }
This is the tire's "seria l number" It begins with the letters "DOT" and
indicates that the tire meets a ll federa l standards . The next two
numbers or letters indicate the plant where it was manufactured,
and the last four numbers represent the week and year of manufac­
ture. For example,
DOT ... 2208 ...
means that the tire was produced in the 22th week of 2008 . T he
other numbers are marketing codes that may or may not be used by
the tire manufacturer . This information is used to contact
consumers if a tire defect requires a reca ll.
Vehicle capacity weight

Because technical changes may be made to vehicle equipment
during the mode l year, always compa re the tire size designation on
the tire pressure label on your vehic le with the tires on your vehicle.
Make sure that the tire size information on the vehicle labe l is the
same as the size of the tires on the vehicle . This is especially impor­
tant if the vehicle belongs to someone else or you bought the
veh ic le with different rims/tires or you bought the vehicle as a previ ­
ously owned vehicle.
Remember, your safety and that of your passengers also depends
on making sure that load limits are not exceeded. Vehicle load
includes everybody and everything in and on the vehicle . These load
limits are technically referred to as the vehicle's Gross Vehicle
Weight Rating ("GVWR"l. The Gross Axle Weight Rating ("GAWR"l is
the maximum load that can be applied at each o f the vehicle's two
ax les . The Gross Vehic le Weight Rating and the Gross Ax le Weight

Checking tire pressure
The correct tire pressure for the tires originally installed
o n your vehicle is listed on the tire pressure label located
either on driver's side 8 -pil/ar or inside the fuel filler flap .
The recommended tire pressures are on the tire pressure label and
in the table=>
page 351, "Cold tire inflation pressure" .This means
that the pressure must be checked and adjusted when the tire has
not been driven for more than a couple of mi les (kilomete rs} at low
speeds during the previous three hours. Air in the tires expands
when the tire heats up as a result of internal fric tion as i t flexes in
use. The tire pressure is higher when the tire has warmed up than
when it is "cold ."
It is the inflation pressure in a "cold" tire that counts. Therefore, you
should never let air out of a warm tire to match "Co ld tire inflation
pressure" recommendations=>
page 351 . The tires wou ld then be
underinflated and could fail suddenly.
The tire pressure label on your Audi lists the recomme nded cold tire
inflation pressures at maximum capacity for the new, origina l equip -.,.
