Automatic car wash
The vehicle can be washed in almost any
modern automatic car wash .
The vehicle paint is so durable that the vehicle
can normally be washed without problems in
an automatic car wash. However, the effect on
the paint depends to a large extent on the de­
sig n of the fac ility, the filtering of the wash
water, the type of wash and care mater ial , etc.
If the paint has a dull appearance afte r go ing
through the car wash or is scratched, bring
this to the attention of the operator immedi­
ately. If necessary, use a different car wash.
Before going through a ca r wash, be s ure to
take the usual precautions such as closing the
windows. Remove antenna if applicable .
If you have installed additional accessories on
the vehicle -such as spoilers, e tc. -it is best to
ask the car wash operator i f these should be
removed .
A WARNING
Always read and heed all WARNINGS and
the information ¢
page 164.
(D Note
- Fold the exterior mirrors -flat the re is a
risk of damaging the exterio r mirrors .
Power folding exterior mi rrors must not
be fo lded in or out by hand. Use the pow­
er function!
- Compare the track of your vehicle w ith
the d istance between the guide ra ils of
the facility- there is a risk of damage to
the wheels and tires .
- Compare the width of your vehicle wit h
the width of the tu nnel at the fac ility.
Washing the vehicle by hand
A lot of water is needed when washing a vehi­
cle by hand.
~ Befo re you start washing, make sure you
have read and understood the WARNINGS

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 227.
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.

-Never mount used tires on yo ur vehicle if
yo u 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.
- If you notice unusual vibration or if the
vehicle pulls to one side when d riving, al­
ways stop as soon as it is safe to do so
and check the wheels and tires for dam­
age .

206 Tires and wheels
Tire service life
The service life of tires depends on a lot of
different things including proper installation
and balancing, correct tire pressure and driv­
ing style.

Fig. 145 Rotating t ires for more ev en wea r
Tread Wear Indicator (TWI)
The original tires on your vehicle have
1/16 inch (1.6 mm) high "wear indicators"
c::> fig . 144 running across the tread. Depend­
i ng on the make, there will be six to eight of
them evenly p laced around the tire. Marks on
the tire sidewa ll (for example "TWI" or other
symbols) indicate the positions of the tread
wear ind icators . Worn t ires must be replaced .
Different figures may apply in other countries
c::> & .
Tire pressure
Incorrect tire pressure causes premature wear
and can cause sudden t ire blow-out. For th is
reason, tire pressure must be checked at least
once a month
c::> page 202 .
Driving style
Driving fast around curves, heavy acceleration
and hard braking increase tire wear.
Rotating tires for more even wear
For all four tires on your vehicle to have the
same service life, we recommend that the
front and rear tires are rotated according to
the tire manufacturer's suggested tire rota­
tion intervals. Please remember the follow­
ing :
- Tire rotation intervals may differ from the
vehicle service interva ls outlined in your
Warranty
& Maintenance Booklet.
- The longer one tire is used in one location
on the vehicle, the more it wears at certain
points; therefore, we recommend that you
follow the tire manufacturer's suggested
tire rotation intervals .
- Vehicles with front-wheel drive experience
more tread wear on the front wheels com­
pa red to all-wheel drive (quattro ®).
- Please rotate tires as shown
c::> fig. 145.
-Extra care must be taken when rotating di-
rection-specific tires
c::> page 22 7 .
Wheel balancing
The wheels on new vehicles are balanced.
However, various situations during everyday
driving can cause them to become unbal ­
anced, re sulting in vibrat ions you can usually
feel through the steer ing wheel.
Unbalanced wheels must be rebalanced to
avoid excessive wear on steering, suspension
and tires. A whee l must also be rebalanced
when a new tire is installed.
Incorrect wheel alignment
Incorrect wheel alignment can cause exces ­
sive tire wear, impairing the safety of the veh i­
cle. If tires show excessive wear, have the
whee l alignment checked by an authori zed
Audi dealer or qualif ied workshop.
all-wheel drive
Vehicles with quattro ® mus t always have tires
of the same size, construction and tread type .

tire meets all federal standards . The next two
numbers or letters indicate the p lant where it
was manufactured, and the last four numbers represent the week and year of manufactu re.
Fo r example, the numbers 2211 mean that
t he t ire was produced in the 22nd week of
2011. 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

210 Tire s and wheel s
Driving with different tires reduces vehi­
cle handling and can lead to a loss of
co ntrol.
- If the spare tire is not the same as the
t ires that are mounted on the veh icle -
for example with winter tires - on ly use
the spare tire for a short period of time
and dr ive with extra ca re. Refit the nor­
ma l road whee l as soon as safely possi­
ble.
- Never drive faste r than the maximum
speed for which the tires o n your veh icle
are ra ted because ti res th at are driven
faster than their rated speed can fail
sudden ly .
- Over loading t ires c ause heat b uild- up,
sudden tire failure, including a blowout
and sudden deflation and loss of control.
- T emperature grades app ly to tires t hat
are properly inflated and not over o r un­
derinflated.
- F or technical reasons it is not a lways
possible to use wheels from other
vehicles -in some cases not even w heels
from the same vehicle model.
- If you insta ll wheel trim discs on t he ve­
hicle whee ls, make sure that the air f low
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 t ires may on ly be used on
vehicles that were equ ipped w it h them
at the facto ry. The vehicle must have a
chassis des igned for run f lat t ires and a
fac to ry-installed t ire p ress ure moni to r­
ing system that ind ic a tes a loss of tire
pressure. Incorrect use of run flat tires
can lead to vehicle damage or accidents .
Check with an a uth orized Audi dea ler or
t i re spec ialist to see i f your vehicle can be
equipped with run flat tires. If r un flat
t ires a re used, they must be installed on
all four wheels . M ixing tire types is not
permitted . (D Note
-For technical reasons, it is not generally
poss ible to use the w heel rims from oth­
er ve hicles. T his can hold tr ue for wheels
of the same vehicle type.
- If the spare tire is diffe rent from the
tires that you have mounted on your ve­
hicle (for 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 w it h the
ti re mat ching the othe rs on your vehicle
as soon as possi ble.
- N ever d rive without the valve stem cap.
T he v alves co ul d get damaged.
@ For the sake of the environment
Dis pose of o ld tires in accordance w ith the
l ocal requirements.
Uniform tire quality grading
- Tread wear
- Tra ction AA A B (
- Temperature ABC
Quality grades can be found where applicab le
o n the tire s ide wall between tread shoulder
and maximum section width
¢ page 207,
fig. 146.
For example: Tread wear 200 , Traction AA,
Temperature A.
All passenger car ti res must conform to Feder­
al Safety Req uirements in add ition to these
grades .
Tread wear
The tread wear g rade is a comparative rating
based on the wear rate of the tire when tested
u nder contro lled conditions o n a specified
government test course.
F o r example, a tire gra ded 150 wo uld wear
one and one ha lf (11/2) times as well on the
government course as a ti re graded 100.
