182 Cleaning and protection
• Wipe the windows dry with a clean piece of
cloth or kitchen paper towel.
The best way to remove snow from w indows
and mir rors is to use a brush. Use a non -abra­
sive
pla stic ice scraper -better still, a spray
deicer -to remove
ic e from windows and mir­
rors.
The windows must not be cleaned with insect remover or wax since these can interfere with
the function of the windshield wiper blades (chatter).
O il, grease or silicone residue can be removed
with
glass cle aner or silicone remo ver. How­
ever, wax residue req uires the use of a specia l­
ly form ulated solvent. P lease contact your au­
thor ized Audi dealer for adv ice on safe prod­
ucts for wax removal.
Windows sho uld a lso be cleaned on the inside
at regular interva ls.
Never dry windows with the same chamois
that you use to dry painted s urfaces. Wax resi­
due on the chamois can impair vision thro ugh
the windows.
A WARNING
- The windshie ld m ust not be treated with
water-repellent materials. They can i n­
c rease glare under poor visib ility condi­
t ions such as wetness, darkness, o r whe n
the sun is low on the hori zon. In addi­
t io n, they ca n cause the wi ndshield wip ­
ers to chatter .
- Always read and heed all WARN INGS and
othe r inform ation
Qpage 178.
0 Note
- Never use warm or hot water to remove
s now and ice from windows a nd mirrors.
This cou ld cause the g lass to c ra ck .
- To prevent damage to the wi res of the
r ear defogger, do not place any adhesive
sticke rs o n the inside of t he rear w indow
ove r the wires.
- To he lp prevent d irt from s cratch ing the
window, always scrape i n a forwar d di- rec
tion -pushing the sc raper away from
you -never bac k and fort h.
Steel wheels
Applies to vehicles: with steel wheels (e .g. if refitted with
winter tires)
The wheels also have to be cleaned.
• Always include the hub caps and wheel rims
when wash ing your vehicle to remove road
dirt, sa lt sprays and brake dust .
If necessary, use a commercial whee l cleaner
to remove accumulated brake dust.
The wheel rims are easier to keep clean i f they
are regularly coated with liq uid wax.
Paint scra tches shou ld be touched up as soon
as possib le to prevent corrosion

Cast (light) alloy wheels
Applies to vehicles : with Cast alloy wheels
-
Cast (light) alloy wheels require special care.
• Wash the w heels with a sponge or hose
brush every other week .
• For deep cleaning afterwards, use on ly a
ded icated acid-free cast alloy wheel cleaner.
• Rub a coat of
liquid wa x onto the rims every
three month. Be sure to reach and treat all
parts of the rim .
To preserve the decorative appearance of the cast alloy w heels, some special care is neces ­
sary. In addition to road dirt and salt, brake dust is also co rrosive . If left on fo r too long,
brake d ust can cause pitting.
U se only spec ial
acid -free cleaners formulated
fo r alloy r ims . Safe products are ava ilab le at ..,_

your authorized Audi dealer. Never leave the cleaner on the rims longer than specified on
the label. If not rinsed
off promptly, the acid
contained in some cleaners can attack the
threads on the wheel bolts.
Never use abrasive or meta l polishing clean­
ing agents.
If the protective coat ing has been
chipped, e.g. by kicked up road dirt, touch it
up as soon as possible.
A WARNING
-Moisture and ice on brakes may affect
braking efficiency~

Body cavity sealing
-
The body cavity sealing does not need to be
checked.
All body cavities which could be affected by
corrosion have been thoroughly protected at
the factory.
This sea ling does not require any inspection or
addit ional treatment. If any wax should seep
out of the cavity when the ambient tempera­
ture is high, it can be removed with a plast ic
scrape r and a suitab le solvent .
A WARNING
Solvents can be dangerous.
- Benzine is flammable and toxic. If you
use benzine for removing the wax, keep
spar ks, flame and lighted cigarettes
aw ay. Never dump benzine on the
ground, in to open streams or down sew ­
age drains.

Tires
General notes
Tires may be the least appreciated and most
abused parts of a motor vehicle .
Tires may be the least appreciated and most
abused parts of a motor vehicle . Tires are,
however, one of the most important parts of a
vehicle, particularly considering the compara­
tive ly small patch of rubber on each tire that
assures that a ll-impo rtant contact between
you, your vehicle and the road.
Maintaining the correct tire pressure, mak ing
sure that your vehicle and its tires do not have
to carry mo re weight than they can safe ly han­
d le, avoiding damage from road hazards and
reg ularly inspecting t ires for damage includ­
ing cuts, slashes irregu la r wear and ove rall
condition are the most important things that
you can do to he lp avoid sudden tire failure in­
cluding tread separation and blowouts.
Avoiding damage I f you have to drive over a curb or similar ob­
stacle, drive very s low ly and as close as possi ­
b le at a right angle to the curb.
A lways keep chem ica ls includ ing gre ase, o il,
gasoline and b rake fluid off the ti res .
Inspect the t ires regularly for damage (cuts,
cracks or b listers, etc.). Remove any fo reign
bod ies embedded in the treads.
Storing tires Mark tires when you remove them to indicate
the direction of rotation . Th is ensures you to
be ab le to mount them correctly when you re­
install t hem.
When removed, the whee ls or t ires should be
stored in a cool, d ry and preferably dark place .
Store tires in a vertical pos ition if they are not
mounted on rims, in a horizontal pos it ion if
they are mounted on rims. New tire
s
New t ires have to be broken in¢&,. .
T he tread depth of new t ires may vary, accord­
ing to the type a nd make of t ire and the tread
pa tte rn .
Hidden damage
Damage to tires and r ims is ofte n not readily
vis ible . If you notice unusual v ibrat ion or the
vehicle p ulls to one side, th is may ind icate
t h at one of the t ires has been damaged . Th e
t ir es m ust be checked immed iate ly by an au ­
tho rized Aud i dea le r or q uali fied wor ks hop.
Unidirectional t ires
A un idirectional tire can be identified by ar­
rows on the sid ewa ll, that po int in the direc­
t ion the t ire is desig ned to rotate. You mus t
f ol low the specified d irection of rotation . This
is necessary so that these tires can develop
their optimum characterist ics regarding grip,
road no ise, wear and hyd rop laning resistance.
For more information ¢
page 241.
A WARNING
-New tires or tires that are old, worn or
damaged cannot provide maximum con­
trol and braking ability .
-
-New tires tend to be slippery and must
be broken in . To reduce the risk of losing
control, a co llision and ser ious personal
in jur ies, d rive w ith special ca re fo r the
fi rst 350 m iles (560 km).
- Driving with worn or damaged tires can
le ad to loss of control, sudden tire fail­
ure, including a blowou t and sudden de­
fl ation, c rashes and seriou s personal in­
juries . Have wo rn or damaged t ires re­
p laced immediate ly .
- T ires age even if they are not being used
an d can fai l sudden ly, especially at high
speeds. Tires that are more than 6 years
old can only be used in an emergency
and then w ith specia l care and at low
speed.

218 Tires and wheels
This is especia lly important if the vehicle be­
longs to someone else or you bought the vehi­
cle with different rims/tires or you bought the
vehicle as a previously owned vehicle.
Remember, your safety and that of your pas­
sengers also depends on making sure that
load limits are not exceeded. Vehicle load in­
cludes everybody and everything in and on the
vehicle. These load limits are technically refer­
red to as the vehicle's Gross Vehicle Weight
Rating (' 'GVWR"). The Gross Axle Weight Rat­
ing ("GAWR") is the maximum load that can
be applied at each of the vehicle's two axles.
The Gross Vehicle Weight Rating and the
Gross Axle Weight Rating are listed on the
safety compliance sticker label located either
on the driver's side B-pillar or on the inside of
the fuel filler flap. The tire pressure label on
your Audi lists the maximum combined
weight of all of the occupants and luggage or
other cargo that the vehicle can carry. For the
location of the tire pressure label
o fig. 167.
_& WARNING
Overloading a vehicle can cause loss of ve­
hicle control, a crash or other accident, se­
rious personal injury, and even death.
- Carrying more weight than your vehicle
was designed to carry will prevent the
vehicle from handling properly and in­
crease the risk of a loss of vehicle con­
trol.
- The brakes on a vehicle that has been
overloaded may not be able to stop the
vehicle within a safe distance.
- Tires on a vehicle that has been overload­
ed can fail suddenly causing loss of con­
trol and a crash.
- Always make sure that the total load be­
ing transported -including the weight of
a trailer hitch and the tongue weight of a
loaded trailer -does not make the vehi­
cle heavier than the vehicle's Gross Vehi­
cle Weight Rating.
A WARNING
- Incorrect tire pressures and/or underin­
flation can lead to a serious or fatal acci­
dent.
- Incorrect tire pressures and/or underin­
flation cause increased tire wear and can affect the handling of the vehicle.
- Incorrect tire pressures and/or underin­
flation can also lead to sudden tire fail­
ure, including a blowout and sudden de­
flation, causing loss of vehicle control.
Checking tire pressure
The correct tire pressure for the tires original­
ly installed on your vehicle is listed on the tire
pressure label located either on driver's side 8-pillar or inside the fuel filler flap.
The recommended tire pressures are on the
tire pressure label and in the table
o page 216, 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 miles (kilometers) at
low speeds during the previous three hours.
Air in the tires expands when the tire heats up
as a result of internal friction as it flexes in
use. The tire pressure is highe r 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 "Cold tire inflation
pressure" recommendations
o page 216. The
tires would then be underinflated and could
fail suddenly.
The tire pressure label on your Audi lists the
recommended cold tire inflation pressures for
the new, original equipment tires that were
on your vehicle at the time it was manufac­
tured. For the location of the label
opage 216, fig. 167.
Most tires lose air naturally over time . They
can also lose some air if you drive over a pot­
hole or hit a curb while parking. It is usually
not possible to see whether the radial tires ..,.

unbalanced, resulting in vib rations you can
usually feel through the steering wheel.
Unba lanced wheels mus t be rebalanced to
avoid excessive wea r on s teer ing, suspens ion
and tires. A wheel must a lso be rebalanced
when a new tire is installed.
Incorrect wheel alignment
Inco rrect whee l alignment can cause exces­
sive tire wea r, impair ing t he safety of the veh i­
cle. If t ires show excess ive wear, have the
wheel alignment checked by an authorized
Audi dealer or qualified workshop.
All Wheel Drive
Ve hicles w it h quattro ® must always have t ires
of the same s ize, construction and tread type.
F or details see
¢ pag e 166 .
A WARNING
Sudden tire failure can lead to loss of con­
tro l, a crash and serious persona l injury!
- Never drive a veh icle when the tread on
any t ire is worn down to the wear indica­
tors.
- Worn tires are a safety hazard , they do
not grip well on wet roads and increase
your risk of"hydrop lan ing" and loss of
co ntrol.
- Always keep chemicals that can cause
tire damage, such as grease, oil, gasoline
and brake fluid away from tires.
- 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 lower
speeds .
- Never mount used tires on yo ur vehicle if
you 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 s udden tire failure
and loss o f vehicle con trol.

U.S . DOT T ire Identific ation Numbe r (TIN)
and tire manufacture date
This is the t ire's "serial number" . It begins
with the lette rs "DO T" and indicates that the
tire meets all federal sta ndards. The next two
n umbers or le tters indica te the p la nt where it
was manufactured, and the last four numbers
represent the week and year of manufacture.
F or example, the numbers 2209 mean that
the t ire was produced in the 22nd week of
2009 . The other numbers are marketing co­
des that may or may not be used by the t ire
manufacturer . This information is used to con ­
tact consume rs if a tire defect requires a re­
call.
Aud i Original tire
Tires with the ident ificat io n "AO" or "RO" have
been spec ially matched with your Aud i. We
recommend using only t hese tires because
they meet the highest standards regard ing

.&_ WARNING ~
- Using incorrect o r unmatched tires and/
or wheels or improper tire and wheel
comb inat ions can lead to loss of control,
col lis ion and serious personal inj ury.
- Always use t ires, rims and whee l bolts
that meet the specifications of original
factory- installed tires or other combina­
tions that have been specifically ap­ proved by the vehicle manufacture r.
- T ires age even i f they are not being used
and can fail sudden ly , e specially at hig h
speeds. Tires that are more than 6 ye ars
old can only be used in an emergency
an d then w ith speci al care and at lower
speeds .
- Never mo unt used t ires on your veh icle if
you are not sure of thei r "previous histo­
ry." O ld used tires may have been dam ­
aged even though the damage cannot be
seen that can lead to sudden tire fai lure
and loss of vehicle control.
- All fou r whee ls must be fitted with radial
tires of the same type , size (rolling cir­
cumference) and the same tread pattern.
Driving with different tires reduces vehi­
cle handling and can lead to a loss of
contro l.
- If the spa re tire is not the same as the
tires that are mounted on the vehicle -
for examp le w ith winter t ir e s -only use
the spare t ire fo r a short pe riod of time

226 Tires and wheels
and drive with extra care. Refit the nor­
mal road wheel as soon as safely possi­
ble.
- 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.
- Overloading tires 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 un­
derinflated .
- For technical reasons it is not always
possible to use wheels from other vehi­
cles -in some cases not even wheels
from the same vehicle model.
- If you install wheel trim discs on the ve­
hicle wheels , make sure that the air flow
to the brakes is not blocked. Reduced air­
flow to the brakes can them to overheat,
increasing stopping distances and caus­
ing
a collision.
- Run flat tires may only be used on vehi­ cles that were equipped with them at the
factory. The vehicle must have a chassis designed for run flat tires and a factory­
installed tire pressure monitoring sys­
tem* that indicates a loss of tire pres­
sure . Incorrect use of run flat tires can
lead to vehicle damage or accidents .
Check with an authorized Audi dealer or
tire specialist to see if your vehicle can be
equipped with run flat tires . If run flat
tires are used, they must be installed on
all four wheels. Mixing tire types is not
permitted .
(D Note
-For technical reasons, it is not generally
possible to use the wheel rims from oth­
er vehicles. This can hold true for wheels
of the same vehicle type.
- If the spare ti re is different from the
tires that you have mounted on your ve­
hicle (for example winter tires or wide
profile tires), then use the spare tire for a short period of time only and
drive with
extra care. Replace the flat tire with the
tire matching the others on your vehicle
as soon as possible.
- If you put different wheels and tires on
your vehicle (e .g. winter wheels and
tires), you must be certain that the
wheels and tires are compatible with the
tire pressure monitoring system* . Other ­
wise the system will register a malfunc­
tion and a fault message will be dis­
played. For more information, contact
your authorized Audi dealer.
- Never drive without the valve stem cap .
The valves could get damaged .
@ For the sake of the environment
Dispose of old tires in accordance with the
local requirements.
Uniform tire quality grading
- Tread wear
- Traction AA A B C
- Temperature ABC
Quality grades can be found where applicable
on the tire side wall between tread shoulder
and maximum section width
¢ page 223,
fig. 171 .
For example: Tread wear 200, Traction AA,
Temperature A.
All passenger car tires must conform to Feder­
al Safety Requirements in addition to these
grades .
Tread wear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified
government test course.
For example, a tire graded 150 would wear
one and one half (11/2) times as well on the
government course as a tire graded 100.
The relative performance of tires depends
upon the actual conditions of their use, how-
ever, and may depart significantly from the
ll-

@ Tips
-Where snow chains are mandatory on
certain roads, this normally also applies
to vehicles with All Wheel Drive .
- If snow chains are insta lled, the tire
pressures shou ld not be stored in the tire
pressure monitoring system (TPMS).
Otherwise the system could malfunction
¢page 232.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque .
The design of whee l bolts is matched to the
factory installed rims. If different rims are fit­
ted, the correct wheel bolts wit h the right
length and correctly s haped bolt heads must
be used. This ensures that wheels are fitted
secure ly and that the bra ke system f unctions
cor rectly .
In certain circumstances, you may not use
wh eel bolts from a differ ent vehicle -even if it
i s the same mode l.
.&, WARNING
Improperly tig hte ned o r maint ained wheel
bol ts can become loose ca using loss of
cont ro l, a co llision and ser ious persona l in ­
jury.
- Always keep the wheel bolts an d the
threads in the wheel hubs clean so the
whee l bolts can tu rn easily and be pro p­
er ly t ightened.
- Never grease or oil the wheel bo lts and
the threads in the w heel hubs. They can
become loose w hile driving if greased or
o iled, even if tightened to the specified
torq ue.
- Only use wheel bolts t hat belong to the
r im being installed.
- Never use different whee ls bolts on your
vehicle.
- Always maintai n the co rrect tighten ing
torq ue for the wheel bo lts t o reduce the
risk of a wheel loss. If the tightening tor-
Tire s an d wheel s 229
que of t he whee l bolts is too low, they
can loosen and come out when the vehi­
cle is mov ing. If the tig htening torq ue is
too high, the wheel bolts and threads
can be damaged and the whee l can be­
come loose.
(D Note
The specified torque for the whee l bolts is
90 ft lb (120 Nm) with a tolerance of± 7,4
ft lb(± 10 Nm). Torq ue whee l bolts diago­
nally. After changing a whee l, the tor que
must be checked as so on as possible with a
torq ue w rench -prefe rably by an au thor ­
iz ed A udi de aler or qu alified workshop .
Low aspect ratio tires
Your Audi is factory -eq uipped w ith low aspect
r atio tires . These tires have been tho ro ughly
tested and been se lected specifically for your
model for their superb performance, road fee l
and handli ng u nder a var iety of driving condi­
tions . Ask your au thorized Aud i dealer for
more d etails.
The low aspect ratio of these t ires is ind icated
by a numeral of
55 or less in the tire's s ize
designation . The numera l represen ts the ratio
of the t ire's sidewa ll height in relation to its
t read width exp ressed in perce ntage. Conven­
tiona l tires have a he ight/w idth ratio of 60 o r
more.
The performance of low-a spect-ratio tires i s
particularly sensitive to improper inflation
pre ssure.
It is therefore important that low
aspect ratio tires are inflated to the specified
pres sure and that the inflation pressure is
regularly checked and maintained. Tire pre s­
sures should be checked at least once a month and always befo re a long trip
¢ page 218, Checking tire pressure.
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damaged mo re
easily by impact w it h potholes, curbs, gul lies ..,.
