2012 AUDI A5 COUPE rims

The best way to remove snow from windows
and mirrors is to use a brush. Use a non-abra­
sive
plastic ice scraper -better still, a spray
deicer -to remove
ice from windows and mir­
rors.
The windows must not be cleaned with insect
remover or wax sin ce these can interfere with
the function of the windshield wiper blades
(chatter).
Oil, grease, or silicone residue can be removed
with
glass cleaner or silicone remover. How­
ever, wax residue require s the use of a special­
ly formulated solvent. Please contact your au­
thor ized Audi dealer for advice on safe prod­
ucts for wax removal.
Windows should also be cleaned on the inside
at regular intervals.
Never dry windows with the same chamois
that you use to dry painted surfaces. Wax resi­
due on the chamois can impair vision through
the windows.
A WARNING
-Always read and heed all WARNINGS and
other information
r::.> page 221.
- The windshield must not be treated with
water-repellent materials. They can in­
crease glare under poor visibility condi­
tions such as wetness, darkness, or when
the sun is low on the horizon. In addi­
tion, they can cause the windshield wip­
ers to chatter.
- Never use warm or hot water to remove
snow and ice from windows and mirrors.
This could cause the glass to crack.
- To prevent damage to the wires of the
rear defogger, do not place any adhesive
stickers on the inside of the rear window
over the wires.
- To help prevent dirt from scratching the
window, always scrape in a forward di­
rection -pushing the scraper away from
you -never back and forth.
Cleaning and protection 225
-Water leaking from the inside of the rear
windows may damage sensitive electrical components located either under the
rear parcel shelf or in the rear trunk area.
Always ensure that water never leaks
through the body section of the vehicle.
You can do this by using waterproof pro­ tection over the vehicle's electrical com­
ponents (e.g. when installing window
tinting) .
- Damage or malfunction of electrical
components due to water damage or any
other outside influence is not covered by
the Audi New Vehicle Limited Warranty.
See your Warranty
& Maintenance book­
let for additional details about your war­
ranty.
Cast (light) alloy wheels
Cast (light) alloy wheels require special care.
.,. Wash the wheels with a sponge or hose
brush every other
week .
.,. For deep cleaning afterwards, use only a
dedicated
acid-free cast alloy wheel cleaner.
.,. Rub a coat of
liquid wax 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 wheels, some special care is neces­
sary. In addition to road dirt and salt, brake
dust is also corrosive . If left on for too long,
brake dust can cause pitting.
Use only special
acid-free cleaners formulated
for alloy rims. Safe products are available 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 metal polishing clean­
ing agents. If the protective coating has been
chipped, e.g. by kicked up road dirt, touch it up as soon as possible . .,..

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.

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
also be broken-in. To reduce t he risk of
losing control, a collision and se rious
pe rsonal injuries, drive w it h specia l care
for the first 350 miles (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

Because technical changes may be made to
vehicle equ ipment dur ing the model year, a l­
ways compare the tire s ize designation on the
tire pressure label on your vehicle w it h the
tires on your veh icle. Ma ke sure that the tire
size info rmation on the ve hicle label is the

This is especia lly important if the vehicle be­
l ongs to someone else or you bought the vehi­
cle with different rims/tires o r you bought the
vehicle as a previously owned vehicle.
Remember, your safety and that of your pas ­
sengers also depends on mak ing su re that
l oad limits a re not exceeded . Vehicle load in­
cludes everybody and everything in and on the
ve hicle. These load limits are technically refer­
red to as the vehicle's G ross Vehicle We ight Rat

A WARNING
Sudden tire failure can lead to loss of con­
trol, a crash and serious personal injury!
- Never drive a vehicle when the tread on
any tire 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 "hydroplaning" and loss of
control.
- Always keep chemicals that can cause
tire damage, such as grease, oil, gasoline
and brake fluid away from t ires.
- Tires age even if they are not be ing used
and can fail suddenly, especially at high
speeds . Tir es 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 your 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 sudden tire failure
and loss of vehicle control.

U.S. DOT Tire Identification Number (TIN)
and tire manufa ctur e 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 standards . The next two
numbers or letters indicate the p lant where it
w as manufactured, and the last four numbers
represen t the week and ye ar of manufacture .
For example, the numbers 2209 mean that
the t ire was produced in the 22nd week of
2009 . The othe r numbe rs are marketing co­
des that may or may not be used by the t ire
manufacturer. This informa tion is used to con ­
t act consume rs if a tire defect requires a re ­
call.
Audi Original tir e
Tires with the ident ificat ion "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
safety and driving characteristics when used
correctly. Your authorized Audi dealer will

26 6 T ire s and whee ls
- 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 sudden tire failure
and loss of vehicle control.
- All four wheels must be fitted with radial
tires of the same type, size (roll ing c ir­
cumference) and the same tread pattern.
Driv ing with different ti res reduces veh i­
cle handling and can lead to a loss of
control.
- If the spare t ire is not the same as the
t ires that are mounted on the veh icle -
f or example with winte r tires -on ly use
the spare tire for a short period of time
and dr ive with extra care. Refit the nor­
ma l road whee l as soon as safely possi ­
ble.
- Never drive faster than the maximum speed for which the tires on your veh icle
are rated because tires that are driven
faster than their rated speed can fail
suddenly.
- Overloading t ires 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
poss ible to use wheels from other vehi­
cles -in some cases not even whee ls
from the same vehicle model.
- If you install wheel tr im discs on the ve­
hicle whee ls, 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.
0 Note
- For technical reasons , it is not general ly
possib le to use the whee l rims from oth­
er vehicles . This can ho ld true for wheels
of the same vehicle type.
- If the spare tire is different from the
tires that you have mounted on your ve- hicle (fo
r example winter tires or wide
profi le tires), then use the spare tire for a
short period of time only and drive w ith
extra care. Replace the flat tire with the
tire matching the others on your vehicle
as soon as possib le.
- Never drive without the valve stem cap.
The va lves could get damaged.

D ispose of o ld tires in accordance with the
l ocal requirements.
Uniform tire quality grading
- Tread wear
- Traction AA A B C
- Temperature ABC
Quality g rades can be found where applicab le
on the tire side wall between tread sho ulder
and maximum section width

fig . 214.
For exampl e: Tread wear 200, Trac tion AA ,
Tempe rature A.
All passenge r car t ires must conform to Feder­
al Safety Requirements in add ition to these
grades .
Tread w ear
The tread wear grade is a comparative rating
based on the wear rate of the t ire when tested
under controlled conditions o n a specified
government test course.
For example, a tire graded 150 would wear
one and one ha lf (1 1/2) times as well on the
gover nment course as a ti re g raded 100 .
The relative performance of tires depends upon the actual conditions of their use, how­
ever, and may depart s ignificantly from the
no rm due to va riations i n driving hab its, se rv ­
ice practices and differences in road charac ter­
istics and cl imate.
Traction
The traction grades, from highest to lowest,
are AA, A, Band
C. Those grades represent the ..,.

Wheel bolts
Wheel bolts must always be tightened to the
correct torque .
The design of wheel bolts is matched to the
factory installed r ims. If differen t rims are fit­
ted, the correct wheel bolts with the right l ength and correctly shaped bolt heads must
be used. This ensures that wheels are fitted
securely and that the brake system functions
correctly .
In certain circumstances, you may not use
wheel bo lts from a different vehicle -eve n if it
i s the same model
¢ page 295.
_&. WARNING
Improperly tig htened or maintained whee l
bolts can become loose ca using loss of
contro l, a co llision and serious persona l in­
jury.
- Always keep the wheel bolts and the threads in the wheel hubs clean so the
whee l bolts can turn easily and be prop­
erly t ightened.
- Never grease or oil the wheel bo lts and
the threads in the wheel hubs. They can become loose wh ile driving if greased or
o iled, even if tightened to the specif ied
torque .
- Only use wheel bolts that belong to the
rim being installed.
- Never use different whee ls bolts on your
vehicle .
-Always maintain the correct tighten ing
torque for the wheel bo lts to reduce the
risk of a wheel loss . If the tightening tor ­
que of the wheel bolts is too low, they
can loosen and come out when the vehi­
cl e is moving.
If the tightening torque is
too high, the whee l bolts and threads
can be damaged and the wheel can be­
come loose.

Low aspect ratio tires
Your Aud i is factory -equ ipped w ith low aspect
ratio tires . These tires have been tho roughly
tested and been se lected specifically fo r your
model for their superb perfo rmance, road fee l
and hand ling under a var iety o f driving cond i­
tions. Ask your authorized Audi dealer for
more details .
T he low aspect ratio of these t ires is ind icated
by a numeral of
55 or l ess in the tire's s ize
designation. The numera l rep resents the ra tio
of the tire's sidewa ll height in relation to its
tread width expressed in percentage . Conven­
tiona l tires have a he ight/w idth ratio of 60 or
more.
T he performance of low-a spe ct- ra tio tire s is
p ar tic ul ar ly se nsi tiv e to i mprop er i nfl ation
pre ssure. It is the refo re important that low
a spect ratio t ires are inflated to the specified
pr ess ure and that th e inflation pr essur e is
r e gula rly ch ecked and maintain ed. Tir e pre s­
s ure s should b e check ed at l east once a
m onth and alwa ys befo re a long trip
¢ page 258, Checking tire pressure.
What you c an do to avo id tire and rim
damage
Low aspect ratio tires can be damaged mo re
easily by impact w ith potholes, curbs, g ull ies
o r ridges on the road, pa rticularly if the tire is
u nderinflated.
In orde r to minimize the occurrence of impact
damage to the tires of your vehicle, we recom ­
mend that you observe the following p reca u­
tions:
- Always ma inta in recommended inflation
pressu res. Check your tire pressure eve ry
2,000 miles (3,000 km) and add air if neces-
sary . .., •

Tires with unidirectional tread design
Tires with unidirectional tread design must be
mounted with their tread pattern pointed in
the right direction.
Using a spare tire with a tread pattern
intended for use in a specific direction
When using a spare tire w ith a tread pattern
in tended for use in a specific direction, please
note the following:
- The direction of rotation is marked by an
ar­
row on the side of the tire .
-If the spare t ire has to be installed in the in­
correct direction, use the spare tire only
temporarily since the tire will not be able to
achieve its optimum performance character­
istic s with rega rd to aquaplaning, noise and
wear.
- We recommend that you pay particular at­
tention to this fact during wet weather and
that you adjust your speed to match road
conditions.
- Replace the flat tire with a new one and
have it installed on your veh icle as soon as
possib le to restore the handling advantages
of a unid irectiona l tire .
Notes on wheel changing
Please read the information c:> page 263, New
tires and replacing tires and wheels
i f you are
going to use a spare t ire which is different
from the tires on your veh icle.
After you change a tire :
-Check the tire pressure on the spare imme­
diately after installation .
- Have the wheel bolt tightening torque
checked with a torque wrench as soon as
possible by your authorized Audi dealer or
a qualified workshop.
- With steel and alloy wheel rims, the wheel
bolts are correctly tightened at a torque of
90 ft lbs . (120 Nm).
- If you notice that the wheel bolts are cor­
roded and difficult to turn while changing
a tire, they should be replaced before you
check the tightening torque. What do I do now? 2 79
- Replace the flat tire with a new one and
have it installed on your vehicle as soon as
possible. Remount the wheel cover.
Until then , drive with extra care and at re­
duced speeds.
A WARNING
-
- If you are going to equ ip your vehicle
with tires or rims which differ from those
which were factory installed, then be
sure to read the information
c:> page 263,
New tires and replacing tires and
wheels.
- Always make sure the damaged wheel or
even a flat tire and the jack and tool kit
are properly secured in the luggage com­
pa rtment and are not loose in the pas­
senger compartment.
- In an accident or sudden maneuver they
could fly forward, injuring anyone in the
veh icle.
- Always store damaged wheel, jack and
tools securely in the luggage compa rt­
ment. Otherwise, in an accident or su d­
den maneuver they could fly forward,
causing injury to passengers in the vehi­
cle.
