Speed warning system
Overview
The speed warning system helps you to keep your driving
speed below a set speed limit.
The speed warning system warns if the driver exceeds a previously stored maximum speed . A warning tone wi ll sound as soon as the
vehicle speed exceeds the set speed by about 3 mph (3 km/h) . At the
same time, a warning symbol appea rs in the display. The symbol's
appearance might be different in some models.
The speed warning system has
t w o wa rning thr esholds that func ­
tion independent ly o f each other and that have somewha t di fferent
purposes:
S p eed war ning 1
You can use speed warning 1 to set the maximum speed while you
are driving. This setting will remain in effect un til you turn off the
ignition, assuming that you have not changed or res et the setting.
The speed warning symbol
8 (USA mode ls)/ 8 (Canada models) in
the warning 1 disp lay appears when you exceed the maximum
speed. It goes out when the speed falls be low the stored maximum
speed . T
he speed warning symbol wi ll also go out if the speed
exceeds the
stored maximum speed by more than about 25 mph
(40 km/h) for at
least
10 seconds . The stored maximum speed is deleted.

S peed w arning 2
Storing warning 2 is recommended if you always want to be
reminded of a certain speed, for example when you are traveling in
a country that has a general maximum speed limit, or if you do not
want to exceed a specified speed for winter tires.
T he speed warning 2 symbol,
8 , (USA models)/ 0 (Canada models)
appears in the display when you exceed the stored speed limit .
Un like warning 1, it wi ll not go out until the vehic le speed drops
b el ow the stored speed limi t.

[ i ] Tips
Even though your vehicle is equipped with a speed warning system,
you shou ld still watch the speedometer to make sure you are not
driving faster than the speed l im it . •

• Be aware of the different than usual steering response and
adjust your steering force accordingly.
• Have the problem checked and set right by an Audi dealer as
soon as possible.
[ i] Tips
• When the engine is running, never hold the steering wheel
turned all the way to the right or to the left for longer than 15
seconds. The power steering pump will overheat the hydraulic fluid
if you keep holding the steering wheel turned all the way. This is
likely to damage the power steering system.
• If the power steering system should fail en tirely, or if the engine
is not running (for example, while being towed), you will still be able
to steer the vehicle . However,
considerably more effort will be
required to do so.
• If the power steering system should have a leak, or is not func­
tioning properly, contact your authorized Audi dealer immediately.
• The power steering system requires a specially formulated
hydraulic fluid. The power steering reservoir is the one located
farthest to the rear on the left side of the engine compartment
=>
page 272. The correct fluid level in the reservoir is important for
proper functioning of the power steering .•
Driving with your quattro®
With all wheel drive, all four wheels are driven.
General information
With all wheel drive, power is distributed to all four wheels. This
happens automatically depending on your driving style and the
road conditions at the time. See also=>
page 235, "Electronic differ­
ential lock (EDU".
The all wheel drive concept is designed for high engine power. Your
vehicle is exceptionally powerful and has excellent driving charac -teristics both under normal driving conditions and on snow and ice.
Always read and
follow safety precautions =>& .
Winter tires
When driving 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-season tires) for improved
driveability and braking : these tires must be mounted on
all four
wheels.
See also => page 304, "Winter tires".
Tire chains
Where tire chains are mandatory on certain roads, this normally
also applies to vehicles with all wheel drive =>
page 305, "Snow
chains".
Replacing vvheels/tires
Vehicles with all wheel drive must always have tires of the same
si ze . Also avoid tires with different tread depths. For details see
page =>
page 299, "New tires and replacing tires and wheels".
Off-Road driving?
Your Audi does not have enough ground clearance to be used as an
off-road vehicle. It is therefore best to avoid rough tracks and
uneven terrain as much as possible. Also refer to=>
page 244.
& WARNING
Always adjust your driving to road and traffic conditions. Do not
let the extra safety afforded by all wheel drive tempt you into
taking extra risks.
• Although the all wheel drive is very effective, always remember
that braking capacity is limited by tire traction. You should there ­
fore not drive at excessive speeds on icy or slippery road surfaces.
• On wet road surfaces, be careful not to drive too fast because
the front wheels could begin to slide on top of the water (aqua­
planing). If this should occur, you will have no warning from a
sudden increase in engine speed as with a front-wheel drive

Sidewall
means that portion of a tire between the tread and bead.
Speed rating means the speed at which a tire is designed to be driven for
extended periods of time. The ratings range from 93 mph (150 km/h)
to 186 mph (298 km/h)=>
page 300. You may not find this informa ­
tion on a ll tires because it is not required by law.
The speed rating letter code, where applicable, is molded on the tire sidewa ll and indicates the maximum perm issible road speeds=>
&
in "Winter tires" on page 304.
Tire pressure monitoring system*
means a system that detects when one or more of a vehicle 's tires
are under inflated and illuminates a low tire pressure warning te ll­
tale.
Tread
means that portion of a tire that comes into contact with the road.
Tread separation
means pu lling away of the tread from the tire carcass.
Treadwear indicators (TWI)
means the projections within the principa l grooves designed to give
a visual indication of the degrees of wear of the tread . See
=>
page 297, "Tread Wear Indicator (TWI)" for more information on
measuring tire wear.
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 al l 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 ... 2209 ...
means that the tire was produced in the 22nd week of 2009 . The
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
means the rated cargo and luggage load plus 150 lbs. (68 kilograms)
times the vehicle's tota l seating capacity as listed on the label
located either on the driver's side 8-pillar or on the inside of the fuel
filler flap.
Vehicle maximum load on the tire
means that load on an individual tire that is determined by distrib­
uting to each axle its share of the maximum loaded vehicle weight
and dividing by two.
Vehicle normal load on the tire
means that load on an individual tire that is determined by distrib­
uting to each axle its share of the curb weight, accessory weight,
and normal occupant weight (distributed in accordance with table
below =>
page 291) and dividing by two. _..

Audi-approved specification tires are specially matched to your
vehicle and its load limits, and can contribute to the important road ­
holding, driving characteristics, and safety of the vehicle . The table
(~ page 291) lists specifications of the tires approved for the Audi
models covered by your Owner's Literature.
The tire pressure label (On USA vehicles, the tire pressure label is located on the driver's side 8 -p illar. On Canada vehicles, the tire
pressure label is located either on the driver's side B-pillar or inside
t he fue l filler flap)( ~
page 291, fig. 230) lists the specifications of
the origina l equipment tires instal led on your vehicle at the time it
was manufactured.
Federal law requires tire manufacturers to place standardized infor ­
mation on the sidewa ll of all tires~
page 299, fig. 233 . This informa­
tion identif ies and describes the fundamenta l characteristics, the
quality grade of the tire and a lso provides a tire identification
number for safety standard certificat ion and in case of a recall.
Tir e s pec ifica tio ns
Knowledge of tire specifications makes it easier to choose the
correct tires . Radial tires have the tire specifications marked on the
sidewa ll, for example:
P255 / 3 5 R19 96V XL
This contains the fo llowing information:
P Indicates the tire is for passenger cars (where applicable)
25 5 Nominal tire width in mm of the tire from sidewall edge to side -
wa ll edge. In general, the larger the number, the wider the t ire
3 5 Height/width ratio in percent (aspect ratio)
R T ire construction: Radial
19 Rim diameter code (in inches)
96 Load rating code
Y Speed rating letter code
XL (or "xi", "EXTRA LOAD", or "RF" Indicates that the tire is a"Rein­
forced" or an "Extra Load" tire
M+ S (or "M/S") Indicates that the t ire has some mud and snow capa-
bility
The ti res cou ld also have the information of direction of rotation

& WARNING
• Using incorrect or unm atched t ires and / or wheels o r improper
tire and wheel combinations can lead to lo ss of control , collision
and se rious per sonal injury .
• Always use tires , rim s and wheel bolts that meet the specifica ­
t ions of original f actory -installed tire s or other combinations that
have been spe cifically approved by the vehicle manufacturer .
• T ires age even if they are not being used and can fail suddenly ,
especially at high speeds . Tires that are more than 6 years old c an
only be used in an emergen cy and then with spec ial care and at
lower speeds .
• Never mount used tires on your vehi cle if you are not sure of
their "previou s history." Old used tires may have been damaged
e ven though the damage cannot be seen that can lead to sudden
tire failure and loss of vehicle control.
• All four wheels must be fitted w ith radial tires of the same type ,
size (rolling circumference ) and the same tread pattern . Driving
with different tires reduces veh icle handling and can lead to a loss
of control.
• If the spare t ire is not the same as the tires that are mounted
on the vehicle -for example with winter tires -only use the spare
tire for a short period of time and drive with e xtra care . Refit the
normal road wheel as soon as safely possible.
• Never drive faster than the ma ximum speed for which the tires
on your vehicle are rated because tires that are driven faster than
their rated speed can fail suddenly .
• Overloading tires cause heat build -up , sudden tire failure,
in cluding a blowout and sudden deflation and lo ss of control.
• Tempe rature grades apply to tires that are properly inflated and
not over or under inflated .
• For technical reasons it i s not always po ssible to use wheel s
from other veh icles - in some cases not even wheels from the
same vehicle model .
& WARNING (continued )
• If you install wheel trim discs on the vehicle wheels, make sure
that the air flow to the brakes is not blocked . Reduced airflow to
the brakes can them to overheat , increasing stopping distances
and causing a collision .
• Run flat tires may only be used on vehicles that were equipped
with them at the factory . The vehicle must have a cha ssis designed
for run flat tires and a fa ctory-installed tire pressure monitoring
system* that indicates a loss of tire pressure. Incorrect use of run
flat tires can lead to vehicle damage or acc idents . Check with an
authorized Audi dealer or tire specialist to see if your vehicle can
be equ ipped with run f lat tires . If run flat t ires are used , they must
be installed on all four wheels . Mixing tire types is not permitted.
0 Note
• For technical r eas ons, it is not gen erally possible t o us e the
whee l rims from other veh icles . ihis can ho ld true for whee ls of the
same veh ic le type.
• I f the spare tire is different from the tires that you have mounted
o n yo ur vehicl e (f or example wi nter tires or wide p rofile t ires), then
use the spare tire for a short period of time on ly and drive with extra
care . Rep lace the flat tire wi th the ti re m atchi ng t he o thers on you r
vehic le as soon as possib le.
• I f you should put diff ere nt w heels and tires o n your v ehicle (e. g.
winter wheels and tires), you must be certain that the wheels and
t ires are c ompatib le wi th the tire p ressu re monitoring system* .
Otherwise the system will register a malfunction and a fau lt
mes sage will be displayed . For more info rmation, contact your
author ized Aud i dea ler.

Winter tires
Winter tires can improve vehicle handling on snow and
ice. At temperatures below 45 °F (7 °C) we recommend
changing to winter tires .
In some heavy snow areas, local governments may require true
winter or "snow" tires, those with very deeply cut tread . These tires
should only be used in pairs and be installed on a ll four wheels.
Make sure you purchase snow tires that are the same size and
construction type as the other tires on your vehicle.
Your vehicle is equipped with all -whee l drive, this wi ll improve trac ­
tion during winter driving, even with the standard tires. However,
we strong ly recommend that you a lways equip all four whee ls on
your vehicle with correctly fitted winter tires or all-season tires,
when winter road conditions are expected. This also improves the
vehicle's braking performance and reduces stopp ing distances.
Summer tires provide less grip on ice and snow.
Winter tires (snow ti res) must a lways be fitted on a ll four wheels.
Compatible tire pressure monitoring sensors must be installed on
a ll fou r winter tires for the tire pressure monitoring system* to func ­
tion proper ly=>
page 301.
Ask your authorized Audi dealer or qualified workshop for permitted
wint er tire size s. Use only radial winter tires.
Winter tires lose their effectiveness when the tread is worn down to a depth of 0.157 inch (4 mm).
Only drive with winter tires under winter conditions. Summer tires
handle better when there is no snow or ice on the roads and the
temperature is above 45 °F (7 °C) .
If you have a flat tire, see notes on spare wheel =>
page 299.
Please always remember that winter tires may have a lower speed
rat ing than the tires originally installed on your vehicle at the time
it was manufactured. Please see=>
page 300, "Speed rating (letter code)" for a listing of the speed
rating letter codes and the
maximum speed at which the tires can be driven .
T he speed rating letter code(=>
page 290) is on the side wall of the
tire =>
page 299.
& WARNING
Winter tire s hav e maximum speed l imit s that m ay be lower than

& WARN ING (continued )
• Always maintain the correct tightening torque for the wheel
bolt s to reduce the risk of a wheel loss . If the tightening torque of
the wheel bolts is too low, they can loo sen and come out when the
vehicle is moving . If the tightening torque is too high , the wheel
bolts and threads can be d amaged and the wheel can be come
loose .

Low as pect rat io tires
Yo ur Audi is fac tory-equipped with l ow aspec t ratio tires . Thes e tires
have been thorough ly tested and been selected specifically for your
m odel f or their superb pe rformance, r oad feel and hand ling under
a variety of driving conditions . Ask your authorized Audi dealer for
m ore deta ils .
T he low aspec t rat io of these ti res is indicated by a nu meral o f
55 or
less
in the tire's si ze designation. The numeral represents the ratio
o f the tire's sid ewa ll heig ht in relat ion t o it s tread w idth express ed
in percentage. Conventiona l tires have a height/width ratio of 60 or
m ore .
The performance of low -aspect -ratio tires is particularly sensitive to
improper inflation pressure . It is therefore important that low
aspect ratio tires are inflated to the specified pres sure and that the
i nflation pressure is regularly checked and maintained . Tire pres­
sures should be checked at least once a month and alway s before a
long trip ~
page 293, "Checking tire pr essure".
What you can do to avoid tire and rim damage
Lo w aspec t r ati o t ir es ca n be da maged more easi ly by impact wi th
potholes, curbs, gullies or ridges on the road, particularly if the tire
i s un derinflate d.
In order to minimize t he occurrence o f impac t damage to the t ires
of your vehicle , we recommend that you observe the following
p recau tions:
• Always ma intain recommended inflation pressures . Check your
t ire pressure every 2,000 miles (3,000 k m) and ad d air i f neces sa ry .
• D rive careful ly on roads with potholes, deep gullies or ridges.
Th e impa ct from driving throug h or over such o bstacles can
damage your tires. Impact with a curb may also cause damage to
you r ti res .
• After any impact, immediately inspect your tires or have them
inspected by the neares t autho rize d Audi deale r. R eplace a
damaged tire as soon as possib le.
• I nspect you r tir es eve ry 2 ,0 0 0 m iles (3 ,000 k m) for damage a nd
wear. Damage is not always easy to see. Damage can lead to loss of
a ir and under infla tion , wh ic h co ul d even tually cause tire fa ilu re . If
you believe t hat a tire may have been damaged , rep lace the tire as
soon as p ossi ble.
• T hese tires may wear more quickly than others .
• Please also re member th at, wh ile t hese tir es de liver respo nsive
handling, they may ride less comfortably and make more noise than

Tire pressure monitoring system
Ap plies to v ehicles : w it h tir e p ressure monit orin g system
General notes ..J
Each tire, including the spare (if provided), should be checked
month ly when cold and inflated to the inflation pressure recom­
mended by the vehicle manufacturer on the vehicle placard or tire
inflation pressure label. (If your vehicle has tires of a different size
than the size indicated on the vehicle placard or tire inflation pres ­
sure label, you should determine the proper tire inflation pressure
for those tires).
As an added safety feature, your vehicle has been equipped with a
tire pressure monitoring system (TPMS) that illuminates a low tire pressure tellta le when one or more o f your tires is significantly
under-inflated . Accordingly, when the low tire pressure te llta le i llu ­
minates, you should stop and check your tires as soon as poss ible,
and inflate them to the proper pressure. Driving on a significantly
under -inflated tire causes the tire to overheat and can lead to tire
failure. Under-inflation also reduces fue l efficiency and tire tread
life, and may affect the vehicle's handling and stopping ability.
Please note tha t the TPMS is not a substitute for proper tire mainte­
nance, and it is the driver's responsibility to maintain correct tire
pressure, even if under -inflation has not reached the level to trigger
il lumination of the TPMS low tire pressure te lltale.
Your vehicle has also been equipped with a TPMS malfunction indi ­
cator to indicate when the system is not operat ing proper ly. The
TPMS malfunction indicator is combined with the low tire pressure
tel ltale . When the system detects a ma lfunction, the te lltale w ill flash for approximately one minute and then remain continuously
il lum inated . This sequence will continue upon subsequent veh ic le
start-ups as long as the malfunc tion exists .
When the ma lfunction indicator is illuminated, the system may not
be able to detect or signal low tire pressu re as intended . TPMS
malfunctions may occur for a variety of reasons, including the
insta llation of replacement or alternate tires or wheels on the
vehic le that prevent the TPMS from functioning properly . A lways
check the TPMS malfunction tellta le after replacing one or more
tires or wheels on your vehicle to ensure that the replacement or
a lterna te tires and wheels allow the TPMS to continue to function
properly. •

& WARNING
• If the tire pressure indicator appears in the instrument cluster
display, one or more of your tires is significantly under -inflated .
Reduce your speed immediately and avoid any hard steering or
braking maneuvers. Stop as soon as possible and check the tires
and their pressures . Inflate the tire pressure to the proper pressure
as indicated on the vehicle's tire pressure label
=> page 291.
Driving on a significantly under -inflated tire causes the tire to over ­
heat and can lead to tire failure . Under-inflation also is likely to
impair the vehicle's handling and stopping ability .
• The driver is responsible for maintaining the correct tire pres­
sures . You must check the tire pressures regularly .
• Under certain conditions (such as a sporty driving style , winter
conditions or unpaved roads ), the pressure monitor indicator may
