We recommend that all work on t ires and
wheels be performed by an authorized A udi
dealer. They are familiar with recommended
procedures and have the necessary spec ial
too ls and spare parts as we ll as the proper fa ­
cilities for dispos ing of the old tires .
Authorized Audi dealers have the necessary information about techn ica l requ irements for
installing or changing tires and r ims.
R eplacing t ires and wheel s
Tires shou ld be rep laced at least in pairs and
not individua lly (for example both front tires
or both rear tires together).
Be s ure to read and heed the information to
the tire pressure monitoring system
¢ page 243.
Always buy rep lacement radial tires that have
the same specifications as the t ires approved
for your ve hicle by Audi. Replacement tires
must always have the same load rating speci ­
fication as the original equipment or approved
optional tires listed in the table
¢ page 229.
Audi-approved specification tires are specially
matched to your vehicle and its load limits ,
and can contribute to the important road hold­
ing, driving character istics, and safety of the
veh icle. The table
( ¢ page 229) lists spec ifica­
tions of the t ires approved for the Audi mod­
e ls covered by your Owner 's Literature .

Tire specifications
Knowledge of tire specifications makes it eas­
ier to choose the co rrec t tires . Radial ti res
have the tire specifications marked on the
sidewa ll, for examp le:
255 /40 R 19 100 H XL
This co nta ins the following information :
P Indicates the tire is for passenger cars
(where app licab le)
255 Nom inal tire width i n mm of the tire
from sidewall edge to sidewall edge. In
general, the larger the number, the wider
the ti re

U.S . DOT Tire Identification Number (TIN)
and tire manufacture date
This is the tire's "serial number". It begins
with the letters "DOT" and indicates that the
tire meets all federal standards . The next two
numbers or letters indicate the plant where it
was manufactured, and the last four numbers
r epresent the week and year of manufacture.
F or example, the numbers 4513 mean the tire
was produced in the 45nd week of 2013. The
other numbers are marketing codes that may
or may not be used by the tire manufacturer .
T his information is used to contact consumers
if a tire defect requires a recall.
Audi Original tire
Tires with the identification "AO" or "RO" have
been specially matched with your Audi . We
recommend using only these tires because
they meet the highest standards regarding
safety and driving characteristics when used
correctly . Your authorized Audi dealer will
gladly provide you with more information .
Tire ply composition and materials used
The number of plies indicates the number of
layers of rubber-coated fabric in the tire. In
general, the greater the number of plies, the more weight a tire can support . Tire manufac -

_& WARNING
= -
- Using incorrect or unmatched tires and/
or wheels or improper tire and wheel
combinations can lead to loss of control
collision and serious personal in jury.
'
-Always use tires, 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 manufacturer.
- 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 w ith special care and at lower
speeds.
- Never mount used tires on your veh icle if
you are not sure of the ir "previous histo­
ry." Old used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden tire fa ilure
and loss of vehicle control.
- All four 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
control.
- If the spare ti re 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 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
vehicles -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
vehicles that were equipped with them at the factory. The vehicle must have a
chassis designed for run flat tires. Incor­
rect use of run flat tires can lead to vehi­
cle 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 permit­
ted.
(D Note
- For technical reasons, it is not generally
possible to use the wheel rims from oth-
Tires and wheels 239
er vehicles. This can hold 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 (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.
- 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
- Tract ion AA A B C
- Temperature AB C
Quality grades can be found where applicable
on the tire side wall between tread shoulder
and maximum section width
c;, page 236,
fig. 160.
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 ISO 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
norm due to variations in driving habits, serv­
ice practices and differences in road character-
istics and climate.

Traction
The traction grades, from highest to lowest,
are AA, A, Band
C. T hose grades represent the
tire's ability to stop on wet pavement as measured under controlled conditions on
specified government test surfaces of asphalt
and concrete. A tire marked C may have poor
traction performance
c:> .&. .
Te mp eratu re
The temperature grades are A (the highest),
B, and
C, representing the t ire's resistance to
the generation of heat and its ability to dissi­
pate heat when tested under con trolled condi­
tions on a specified i ndoor laboratory test
wheel.
Sustained high temperature can cause the
material of the tire to degenerate and reduce
tire life, and excessive temperature can lead
to sudden tire failure
c:> ,& .
The grade C corresponds to a level of perform­
ance which all passenger car tires must meet under the Federal Motor Veh icle Safety Stand­
ard No .
109 . Grades Band A represent h igher
l eve ls of pe rformance on the laboratory test
wheel than the m inimum required by law.
.&_ WARNING
T he traction grade assigned to this t ire is
based on stra ight-ahead braking traction
tests, and does not include acceleration,
cornering, hydrop laning o r peak traction
character istics.
A WARNING
The temperature grade for this tire is es ­
tablished for a t ire that is properly inflated
and not overloaded. Excessive speed, un­
derinflation, or excessive loading, either
separately or in combination, can cause
heat buildup and possible tire fa ilu re.

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 w inter o r "snow" t ires, those
with very deeply cut tread . T hese tires should
o n ly be used in pairs and be installed on a ll
f o ur wheels . Make sure you purchase snow
t ir es that are the same size and construction
type as the othe r tires on yo ur vehicle.
If your vehicle is equ ipped w ith all-whee l
drive*, t his w ill improve traction during win ter
driv ing, even with the standard tires . Howev ­
er, we strongly recommend that you always
equip all four wheels on your vehicle w ith cor­
rect ly fitted winter tires or all-season t ires,
when winter road condit ions are expected.
This also improves the veh icle 's brak ing per­
formance and reduces stopping d istances .
Summer tires provide less grip on ice and
snow.
Winter tires (snow tires) must always be fitted on all fo ur whee ls .
Ask your au thorized A udi dealer or qualified
workshop for permit ted
winter ti re size s. Use
only radial winter tires .
Winter tires lose their effec tivenes s whe n the
tread is wo rn down to a depth o f
0.157 inch
(4 mm) .
Only d rive w ith w inter t ires under w inte r co n­
ditions. S umme r tir es handle bette r whe n
the re is no snow o r ice on the roads and the
temperature is above 45 °F (7 °C) .
If you have a flat ti re, see notes on spare
whee l
c:> page 236 .
Please always remember that winter tires may
have a lowe r speed rating than the tires o rigi­
nally i nstalled on your vehi cle at the time it
was manuf actu red. P lease see

ping ability.
- The driver is responsible for maintaining
the correct tire pressures. You must
check the t ire pressures regularly.
- Under certain conditions (such as a spor­
ty driving style, w inter condit ions or un­
paved roads), the pressure monitor ind i­
cator may be de layed.
- Ask your authorized dealer if run-flat
tires may be used on your vehicle. You ve­
hicle registrat ion becomes invalid if you
use these tires when not permitted .
Damage to your vehicle or accidents
c ou ld also resu lt.
(0 Tips
- The t ire pressure monitoring system can
also stop work ing when there is an ESC/
ABS malfunction.
- Using snow chains may result in a system malfunction .
- The t ires with the ident ificat ion "AO" or
"RO"¢ page 236 have been matched
with you r A udi tire p ressu re monito ring

Maintenance
General
Your vehicle has been designed to help keep
maintenance requirements to a minimum.
However, a certain amount of regular mainte­
nance is still necessary to assure your vehicle's
s afety, economy and rel iability. For detailed
vehicle maintenance consult your Warranty &
Maintenance booklet.
Under difficult operating conditions, for ex­
ample at extremely low outside temperatures,
i n very dusty regions , when towing a trailer
very frequently, etc., some service work
should be performed between the intervals
specified. This applies particularly to:
- oil changes, and
- cleaning or replacing the air filter .
(® For the sake of the environment
By regularly maintaining your vehicle, you
help make sure that emission standards
are maintained, thus minimizing adverse
effects on the environment.
Important considerations for you and
your vehicle
The increasing use of electronics, sophisticat­
ed fuel injection and emission contro l sys-
tems, and the genera lly increasing technical
liJJ,

complexity of today's automobi les, have
steadi ly reduced the scope of maintenanc e
and repairs which can be carried out by vehicle
owners.
Also, safety and env ir onm ental con­
cerns p lace very strict limits on the nature of
repairs and adjustments to engine and trans ­
miss ion pa rts which an owner can perform .
Maintenance, adjustments and repa irs usua lly
require special tools, testing dev ices and oth­
er equipment avai lab le to specially trained
workshop personnel in order to assure prope r
performance, reliab ility and safety of the vehi­
cle and its many systems .
Improper ma intenance, adjustments and re ­
pa irs can impair the operation and reliability
of your vehicle and even vo id your vehicle war­
ranty. The refo re, p roof of servic ing in accord­
ance w ith the ma intenance sched ule may be a
condition for upholding a poss ible war ranty
claim made within the warranty period.
Above all, operational safety can be adversely
affected, crea ting unnecessary risks for you
and your passengers.
I f in doubt about any servicing , have it done
by your authorized Audi dealer or any other
p roperly equipped and q ualified workshop .
We strong ly urge you to give your aut horized
Audi dealer the opportunity to perfo rm all
schedu led maintenance and necessary repairs .
Your dea ler has the facilities, or iginal parts
and trained spec ialists to keep your vehicle
running properly .
Performing limit ed m aintenance you rself
The fo llowing pages describe a limited num­
ber of procedures which can be performed on
your vehicle with ordinary too ls, should the
need arise and trained personnel be unavaila­
b le. Before performing any of these proce­
dures, always thoroughly read all of the app li­
cable text and carefully follow the instruc­
tions given. Always rigorously obse rve the
WARNINGS provided .

_& WARNING
- Ser ious personal injury may occur as a re­
sult of improperly performed mainte­
nance, adjustments or repa irs .
- Always be extremely careful when work­
ing on the vehicle . Always follow com­
monly accepted safety pract ices and gen­
era l common sense. Never r isk personal
injury.
- Do not attempt any of the maintenance,
checks or repairs descr ibed o n the fol­
lowing pages if you are not fully fam ilia r
with these or other procedures with re­
spect to the vehicle, or are uncertain how
to p roceed .
- Do not do any work without the proper
too ls and equipment. Have the necessary

er or another proper ly equipped and
qualified workshop.
- The engine compartment of any motor
veh icle is a potentially ha zardous area.
Never reach into t he area around or
touch the rad iator fan . It is temperature
contro lled and can switch on suddenly -
even when the engine is off . T he radiato r
fan switches on automat ically when the
coo lant reaches a certain tempera ture
and will cont inue to run until the coo lant
temperature drops .
- Always sw itch o ff the ignition before any­
one gets under the vehicle.
- Always support your veh icle with safety
s tands if it is necessary to work under­
neath the vehicle. The jack s upplied with
the vehicle is not adequate for this pu r­
pose and cou ld collapse causing serio us
personal injury.
- If you m ust wor k underneath the vehicle
with the wheels on the g round, a lways
make sure the vehicle is on leve l ground,
that the wheels are a lways securely
blocked and that the engine cannot be
