s uit prevailing road , traffic and weather condition s. Never drive
your vehi cle faster than the m aximum sp eed rating of the tires
installed .•
Speed warning system
Overview
The speed warning system helps you t o keep your driving
speed bel ow a set speed limit.
Th e speed wa rning system warns the d river if he exceeds a p reviously
sto red maximum sp eed. A wa rning tone will sound as soon as the
vehicle speed exceeds the set speed by about 3 mph (3 km/h). At the
sa me time, a warning symbol appears in t he d isp lay.
T he speed warning system has
two warning thresholds that function
independen tly of each o ther and tha t have somewha t di ffe rent
purposes:
Speed warning 1
You can use speed war ning 1 to set the max imum speed w hile you are
driving. This setting w ill remain in effect unt il you turn off the igni
tion, assum ing that you have not changed or reset the setting .
Th e spee d warning symbo l
e (USA models)/ 8 (Canada mode ls) in
the warning 1 display appears when you exceed the maxim um speed.
It goes out when the speed falls be low the stored maximum speed.
T he spee d warning symbo l w ill also go out i f the spee d
exceeds the
stored maximum speed by more than about 25 mph (40 km/h) for at
least 10 seconds. The stored maximum s peed is de leted .

Speed warning 2
Storing warn
ing 2 is recommended i f you always want to be reminded
of a certa in speed, fo r example when yo u 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.
The speed warning 2 symbol,

Note
If t he re is an elect ro n ic malfunc tion, servotroni c will still funct io n
like a conventional power steering system, provid ing a constant
steer ing suppo rt force tha t is no longer proportiona te to the vehi cle
speed. This is most noticeable when t urning the steer ing wheel at low
speeds (for ex ample when p arki ng), -m ore effo rt will be req uire d
than usua l.
• Be aw are of the d iffe ren t than usual steeri ng respo nse and adjust
your steering force accord ingly.
• Have t he pr oblem chec ked and set r igh t by a n Audi dea ler as soo n
as possib le .
[I) Tips
• When the engine is runni ng, neve r hold t he steering wheel turned
a ll the way to the r ig ht o r to t he left fo r longe r th an 1 5 seco nd s. The
powe r steering pump will over heat the hydraulic fluid if yo u keep
holding t he s teering w heel turne d all the w ay. This is likely to damage
the power steer ing system.
• If the powe r stee ring sys tem s ho uld fail entire ly, or if the engine
is not running (for examp le, while be ing towed), you will still be able
t o steer the vehicle. Howeve r,
considerably more effo rt will be
required to do so.
• If the powe r stee ring sys tem s ho uld have a leak, or is not func
tioning properly, contact your author ized Audi dealer immediately.
• Th e power s teeri ng system re quir es a specially fo rm ulated
hydraulic fluid. The power stee ring reservoir is the one located
f ar the st to the rea r on t he left side of the eng ine compa rtment
=> page 302. The correct fluid level in the reservo ir is important for
pr op er f unctio ning o f the power steer ing.•
Dr"v ing witr your quattro®

Wit h All Wheel Drive, all four wheels are d riven .
General information
With All Wheel Drive, power is dist ribu ted to all fo ur wheels. This
hap pens a utomat ically depending o n your dr iv ing style and t he road
conditions at the time. See also =>
page 258, "Electronic different ia l
lock (EDL)" .
Winter tires
When d riving in the win ter, your vehicle with A ll Whee l Dr ive has an
advantage, even w ith regula r tir es. In w inter road con ditions i t may
be advisable to mou nt wi nte r ti res (or all-seaso n tires) for improve d
dr iveability and b raking: these tires m ust be mounted on
all four
wheels .
See also=:> page 334, "W inter tires".
Tire chains
Whe re tire chains are ma nda to ry on certa in roa ds, th is no rma lly a lso
ap plies to vehicles with A ll Whee l Drive =:>
page 335, "Snow chains" .
Replacing wheels/tires
Vehicles wit h All W heel Dr ive must a lways have t ires of the same si ze .
Also avoid tires with different tread depths. For details see page
=> pa ge 330, "N ew tires and rep lacing tires and wheels".
& 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 therefore 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 wheel s could begin to slide on top of the water (aqua- ...

Driving off road
- Use the hill descent control~ page 257 when dr iving
down steep sections on hills .
Unpaved roads and offroad
Drive slowly on unfamiliar roads and unknown offroad sections, and
loo k ou t for unexpec ted obsta cles (e.g. potho les, rocks, t ree st umps,
etc.).
T o prevent the vehicle from bottoming and avoid damage to the
unde rbody, you should d rive st raight ac ross severe b umps in the
ground with on ly one s ide of the vehicle so that on ly two of your
w heels cross the bumps.
Drive brisk ly throug h sandy or marshy offroad sections and do not
stop, if at all possible.
Driv ing th rough water
N ote the following to avoid vehicle dam age when driving throug h
water, for example on flooded roads:
• T he wate r must not be any higher than the bottom of the ve hicle
body .
• Do not drive faste r th an wal king speed .
Driving on a slope
If yo u ever find you rsel f not able to climb a slope, do not t ry to turn
around, drive back down in
re verse . Otherw ise, you run t he risk of
t ipping over .
If the vehicle threatens to t ip over when driving across a slope, you
must immediately steer downhill in the direction of the slope.
Do not park yo ur vehicle o n steep s lopes o r gr ad es.
To red uce the risk of tipp ing over, drive on s lopes in the di rect io n of
t he downward slo pe (fa ll line) -
not crosswi se .
Driv ing on snow-covered ground
T he s tandard tires fi tted to yo ur vehi cle are not snow t ires. So yo u
should mount wheels with snow t ires in good t ime where winter road
conditions p revail. Befo re dr iv ing on unp lowed stretches o f deep snow, install tire chains
. For tech nica l reasons, t ire chains may only
be ins talle d on the re a r wheels -never on the front whee ls.
& WARNING
After driving through water , mud, slush, etc. , the brakes may be
slow to take effect because of wet brake rotors and pads.
Dry the
brake s first by braking carefully to re store the full braking effe ct.
0 Note
Vehicle components such as the engine, trans mission, s uspension or
electrical system can be severely damaged by dr iv ing through water.
(I) Tips
• Check the dept h of the water before dr iv in g through it.
• Do not stop the vehicle, dr ive in reverse or sw itch the e ngine off
when driving through water.
• K eep in m ind th at on coming vehicles m ay cre ate w aves t hat ra ise
the water level and make it too deep for your vehicle to drive through
safe ly.
• Avoid dr iving through sa lt water because it ca n cause corrosion .•

Sidewall
means that portion of a tire between the tread and bead.
Speed rating (letter code)
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 331. You may not find this information on
all tires because it is not required by law .
The speed rating letter code, where applicable, is molded on the tire
sidewall and indicates the max imum permissible road speeds=>
& in
"Winter tires" on
page 334.
Tire pressure monitoring system
means a system that detects when one or more of a vehicle's tires are
underinflated and illuminates a low tire pressure warning telltale.
Tread
means that portion of a tire that comes into contact with the road.
Tread separation
means pulling away of the tread from the tire carcass .
Treadwear indicators (TWI)
means the projections within the principal grooves designed to give a
visual indication of the degrees of wear of the tread. See=>
page 328,
"Tread Wear Ind icator (TWI)" for more information on measuring
tire wear.
Uniform Tire Quality Grading
is a tir e information system developed by the United States National
Highway Traffic Safety Administration (NHTSA) that is designed to
help buyers make relative comparisons among tires. The UTQG is not
a safety rating and not a guarantee that a tire will last for a prescribed
number of miles (kilometers) or perform in a certain way. It simp ly
gives tire buyers additional information to combine with other
considerations, such as price, brand loyalty and dealer recommenda
tions. Under UTQG, tires are graded by the tire manufacturers in three
Safety first
areas: treadwear, traction, and temperature resistance . The UTQG
information on the tires, molded into the sidewalls.
U.S. DOT Tire Identification Number (TIN)
This is the tire's "serial number" It begins with the letters "DO T" and
indicates that the tire meets all federal standards. The next two
numbers or letters indicate the plant where it was manufac tured, and
the last four numbers represent the week and year of manufacture.
For example,
DOT ... 2210 ...
means that the tire was produced in the 22nd week of 2010. The
other numbers are ma rket ing codes that may or may not be used by
the tire manufacturer . Th is information is used to contact consumers
if a tire defect requires a recall.
Vehicle capacity weight
means the rated cargo and luggage load plus 150 lbs. (68 kilograms)
times the vehicle's total seating capacity as listed on the label located
on the driver's side B-pillar.
Vehicle maximum load on the tire
means that load on an individua l 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 individua l tire that is de term ined by distrib
uting to each axle its share of the curb weight, accessory weight, and
normal occ upant weight (distr ibuted in accordance with table below

Th e tire pressure label located on the driver's side B-pillar
=> page 322, fig. 242 lists the specifications of the original equ ip
ment tires insta lled on your vehicle at the time it was manufactured.
Federal law requires tire manufacturers to place standardized infor
mation on the sidewall of all tires=>
page 330, fig. 245. This infor
mation identifies and describes the fundamenta l characteristics, the
quality grade of the tir e and also provides a tire ident ification number
for safety standard certification and in case of a reca ll.
Tire specifications
Knowledge of tire specifications makes it easier to choose the correct
tires . Radial tires have the tire spec ifications marked on the s idewall,
for example:
P255 / 55 R 18 109 H XL
This contains the following information:
P Indicates the tire is for passenger cars (where applicable)
255 Nominal tire width in mm of the tire from sidewall edge to side-
wall edge. In general, the larger the number, the wider the tire
55 Height/width ratio in percent (aspect ratio)
R Tire construction: Rad ial

& WARNING
• Using incorrect or unmatched tires and/ or wheels or improper
tire and wheel combinations can lead to loss of control , collis ion
and seriou s personal injury.
& WARNING (co ntinued )
• Always use tires, rims and wheel bolts that meet the specifica
tions of original factory-installed tires or other combinations that have been specifically app roved by the vehicle manufacturer.
• Tires age even if they are not being used and can fail suddenly,
especially at high speeds . Tires that a re more than 6 years old can
only be used in an emergency and then with special care and at
lower speeds.
• Never mount used tires on your vehicle if you are not sure of
their "previous history ." Old used tires may have been damaged
eventhoughthedamagecannotbeseenthatcanleadtosudden
tire failure and loss of vehicle control.
• All four wheels must be fitted with radial tires of the same
type , size (rolling circumference) and the same tread pattern.
Driving with different tires reduces vehicle handling and can lead
to a loss of control.
• If the spare tire 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 extra care . Refit the
no rmal road wheel as soon as safely possible .
• Never drive faster than the maximum speed for which the tires
on your vehicle are rated because tires that are driven faster than
their rated speed can fail suddenly .
• Ove rloading tire s cause heat build-up, sudden tire failure,
including a blowout and sudden deflation and loss of control.
• Temperature grades apply to tires that are properly inflated
and not over or underinflated.
• For technical rea sons it is not always possible to use wheels
from other vehicles- in some cases not even wheels from the same
vehicle model.
• If you install wheel trim discs on the veh icle wheels, make sure
that the air flow to the brakes is not blocked . Reduced airflow to
the brakes can them to overheat , increasing stopp ing distances
and causing a colli sion.

in. WARNING
The traction grade assigned to this tire is based on straight-ahead
braking traction test s, and d oes not include acceleration ,
cornering, hydroplaning or peak tra ction chara cteristics .
in. WARNING
The temperature grade fo r this tire is established for a tire that is
properly inflated and not overloaded. Ex cessive speed, underinfla
tion, or excessive load ing, either separately or in comb inat ion, can
c ause heat buildup and po ssible tire failure. •
Winter tires
Winter tires can improve v ehicl e handling on snow and
ice . At temper atures below 45 °F (7 °C) we recommend
ch anging to w inter tires.
In some heavy snow areas, loca l governme nts may requ ire true
w inter o r "snow" tires, those with very deep ly c ut trea d. These tires
sho uld only be used in pa irs and be installed on all four whee ls. Make
sure you p urchase snow tires that are the same size and construct ion
type as the ot her t ires on your ve hicle.
Your vehicle is equipped with a ll-wheel drive, th is will improve trac
tion dur ing wi nter dr iv ing, even w it h the standar d tires. Howeve r, we
strong ly recommend that you always eq uip a ll four wheels on yo ur
veh icle with correctly fitte d winter t ires or all-season ti res, when
w inte r road conditio ns are exp ect ed. This also imp roves th e veh icle's
bra king perfo rmance an d red uces stopping distances.
S um mer tir es p rovide le ss grip on ice and snow .
Winter tires (snow tires) m ust always be fitted on all four wheels.
Ask your aut horized Audi dealer or q ualified workshop for permitted
winter tire sizes . Use only ra dial w inter tires. W
inter tires lose the ir effectiveness when the tread is wor n down to
a dep th o f 0. 157 inch ( 4 mm).
On ly drive w ith w inter t ires under w inter cond it io ns. S umme r tires
han dle better when the re is no snow or ice on the roads and the
tempe ra ture is a bove 45 °F (7 °C).
If you have a flat tire, see notes on spare wheel=>
page 330.
Please always remember that winter tires may have a lower speed
rat ing than the tires originally installed on yo ur veh icle at t he time it
was man ufact ured . Please see=>
page 331, "Speed rating (letter
c ode)" for a list ing of t he speed ra ting le tte r c odes and the maxi mum
speed at which the tires can be driven .
Th e spee d rat ing let ter code (=>

in. WARNING
Winter tires have maximum speed limits that may be lower than
your vehicle 's maximum speed . Always know the maximum speed
before dr iving off. Never drive faster than the speed permitted for
your specifi c winter tires . This will caus e damage to the tires
lead ing to an accident and serious personal injury to you and your
pa ssengers.
in. WARNING
Driving fa ster than the maximum speed for whi ch the winter tires
on your vehicle were designed can cause t ire failure including a
blowout and sudden deflation , lo ss of control , crash es and seriou s
personal injuries. Have worn or damaged tires replaced immedi
ately.
• Winter tires have maximum speed rating that may be lower
than your vehicle's maximum speed .
• Never drive faster than the speed for which the winter or other
tires installed on your vehicle are rated.
