Tread wear
The tread wear grade is a compa ra tive ra ting based on the wear rate
of the tire when tested unde r co ntrolled conditions on a specified
government test co urse.
For examp le, a tire g rade d 150 would wea r o ne and one half (1 1/2)
times as well on the government course as a tire graded 100.
Th e relat ive performance o f tires depends upon t he ac tual con ditions
o f their use, however , and may de pa rt s ig ni ficantly from the norm
due to variations in driv ing ha bits, service prac tices an d differences in
roa d characterist ics and climate.
Traction
The traction grades, from highest to lowest, are AA, A, Band C. Those
grades represent the tire's ab ility to s to p on wet pavemen t as
meas ured under controlled condit ions o n spec ified governme nt test
s u rfaces of asphalt and conc rete. A tire mar ked C may have poo r trac­
ti on perfo rma nce => & .
Temperature
The temperature grades are A (t he h ighest), B, a nd C, rep resenting
the t ire's resistance to the gene rat ion of heat and its ab ility to dissi­
pate hea t when test ed unde r co ntro lled condi tions o n a spe cifi ed
indoor laboratory test wheel.
S ust ain ed high te m peratu re can cause t he mate rial of the tire to
degenerate and reduce tire life, and excessive temperatu re ca n lead
t o sudden tire fail ur e=> & .
Th e g rade C cor responds to a leve l of performance which all
passenger car tires m ust meet under the Fede ral Motor Vehicle
Safety Standa rd No. 109. G rades Band A rep resent higher levels of
per formance on the labo ratory test whee l than the minimum
req uired by law .
Safety first
& WARNING
The traction grade assigned to this tire is based on straight -ahead
braking traction tests, and does not include acceleration,
cornering, hydroplaning or peak traction characteristics.
& WARNING
The temperature grade for this tire is established for a tire that is
properly inflated and not overloaded. Excessive speed, underinfla­
tion, or e xcessive loading, either separately or in combination, can
c ause heat buildup and po ssible tire failure .•
Winter tires
W inter tires can improve vehicl e handling on snow and
ic e. A t temper atures belo w 45 °F (7 °C) we recommen d
ch angin g to win ter tires .
In some heavy snow areas , loca l gover nments may requ ire true
wi nte r o r "snow" t ires, those with very deep ly c ut trea d. These tires
should only be use d in pairs and be i nstalled on all fo ur w heels . Mak e
sure you purchase snow tires that are the same size a nd constr uction
t ype as the ot her tir es o n your ve hicle.
If your veh icle is eq uipped with all-wheel drive*, th is will improve
t raction during w inte r drivin g, eve n with t he standard tires . However,
we st rongly recomme nd that you a lways equi p all four w hee ls on your
vehicle with correctly fitte d winter t ires or a ll-season ti res, w hen
wi nter road conditions a re expe cte d. Thi s also improves the vehicle 's
bra king pe rformance and re duces stop ping distances.
S u mme r tir es pro vide less g rip on ice and snow .
Winter tires (snow tires) must always be fi tted on all fo ur whee ls .
Ask yo ur autho rized Audi deale r or qu alified wor kshop for permitted
winter tire sizes . Use only ra dial w inte r tir es. ..

Low aspect ratio tires
Your Audi is factory-equipped with low aspect ratio tires. These tires
have been thoroughly tested and been selected specifically for your
model for their superb performance, road feel and handling under a
variety of driving conditions. Ask your authorized Aud i dealer for
more details .
Th e low aspect ratio of these tires is indicated by a numeral of
55 or
less
in the tire's size designation . The numeral represents the ratio of
the tire's sidewall height in relation to its tread width expressed in
percentage. Conventional tires have a height/width ratio of 60 or
more.
The performance of low-aspect-ratio tires is particularly sensitive to
improper inflation pressure. It is therefore important that low
aspect ratio tires are inflated to the specified pressure and that the
inflation pressure is regularly checked and maintained. Tire pres­
sures should be checked at least once a month and always before a
long trip~
page 252, "Checking t ire pressure" .
What you can do to avoid tire and rim damage
Low aspect ratio tires can be damaged more easily by impact w ith
potholes, curbs, gullies or ridges on the road, particularly if the tire is
unde rinflated.
In order to minimize the occurrence of impact damage to the tires of
your vehicle , we recomme nd that you observe the following precau ­
tions:
• Always maintain recommended inflation pressures. Check your
tire pressure every 2,000 miles (3,000 km) and add air if necessary.
• Drive ca refully on roads with potholes, deep gullies or ridges. The
impact from driving through or over such obstacles can damage your
tires. Impact with a curb may also cause damage to your tires .
• After any impact, immediately inspect your tires or have them
inspected by the nearest authorized Audi dealer. Replace a damaged
tire as soon as possible. •
Inspect your tires every 2,000 miles (3,000 km) for damage and
wear . Damage is not always easy to see. Damage can lead to loss of
air and underinflat ion, which could eventually cause tire fa ilure . If
you believe that a tire may have been damaged, replace the tire as
soon as poss ible .
• Th ese tires may wear more quickly than others.
• Please a lso remember that, while these tires deliver responsive
hand ling, they may rid e less comfortably and make more noise than
other choices .
Reduced performance in winter/cold season
conditions
All tires are designed for certain purposes. The low aspect ratio, ultra
high performance t ires originally installed on your vehicle are
intended for maximum dry and wet road perfo rmance and handling.
They are not su itable for cold, snowy or icy weather conditions . If you
drive under those circumstances, you should equip yo ur vehicle with
all-season or w inter tires, which offer better traction under those
conditions . We suggest yo u use the recommended snow or all-season
tires specified for your veh icle, or their equivalent .
Refer to =>
page 261 for more detailed information regard ing winter
tires. •
Tire pressure monitoring system
Applies to veh icles : w it h t ire press ure m onito ring syste m
General notes 1
Each tire, including the spare (if prov ided) , shou ld be checked
month ly when cold and inflated to the inflation pressure recom­
mended by the vehicle manufacturer on the vehicle placard or t ire
inf lation pressure label. (If your vehicle has tires of a different size
than the siz e indicated on the vehicle placard or tire inflation pressure
label, you should determine the proper t ire inflation pressure for
those tires.)
~

________________________________________________ T_ i_ re _ s_ a_ n_d_ w_ h_ e_ e_l _s _ ........
As an added safety feature, your vehicle has been equipped with a tire
pressure monitoring system (TPMS) that ill uminates a low tire pres­
sure telltale when one or more of your tires is signif icantly under­
inflated . Accordingly, when the low tire pressure telltale illuminates,
you should stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving on a significantly under-inflated
ti re causes the tire to overheat and can lead to tire fa ilure. Unde r­
inf lation also reduces fuel efficiency and tire tread life, and may
affect the vehicle's handling and stopping ability.
Please note that the TPMS is not a substitute for proper tire mainte­
nance, and it is the driver's responsibility to maintain correct tire
pressure, even if under -inflation has not reached the level to trigger
illumination of the TPMS low tire pressure te lltale.
Your vehicle has also been equipped with a TPMS malfunction ind i­
cator to indicate when the system is not operating properly. The
TPMS malfunction indicator is combined w ith the low tire pressure
telltale . When the system detects a malfunction, the telltale will
flash for approximate ly one minute and then remain continuously
illuminated. This sequence will continue upon subsequent vehicle
start -ups as long as the malfunction exists.
When the ma lfunction indicator is illum inated, the system may not
be able to detect or signa l low tire pressure as intended. TPMS
ma lfunctions may occur for a var iety of reaso ns, includ ing the instal­
lation of replacement or alternate tires or wheels on the vehicle that
prevent the TPMS from functioning properly. Always check the TPMS
malfunction telltale after replacing one or more tires or wheels on
yo ur vehicle to ensure that the replacement or alternate tires and
wheels allow t he TPMS to continue to funct io n properly .•

& WARNING
• If the tire pressure indicator appears in the instrument cluster
display, one or more of your tires is significantly under-inflated. Reduce your speed immediately and avoid any hard steering or
braking maneuvers. Stop as soon as possible and check the tires
and their pressures . Inflate the tire pressure to the proper pres­
sure as indicated on the vehicle's tire pressure label=>
page 249.
Driving on a significantly under-inflated tire causes the tire to
overheat and can lead to tire failure. Under-inflation also is likely
to impair the vehicle's handling and stopping ability.
& WARNING (co ntinued )
• The driver is responsible for maintaining the correct tire pres­
sures . You must check the tire pressures regularly .
• Under certain conditions (such as a sporty driving style, winter
conditions or unpaved roads), the pressure monitor indicator may
be delayed.
• Ask your authorized Audi dealer if run-flat tires may be used on
your vehicle. Your vehicle registration becomes invalid if you use
these tires when not permitted. Damage to your vehicle or acci­ dents could also result.

For you r safety, we recommend that you have your autho ­
ri zed Audi dealer replace burned out bulbs for you.
It is becoming increasingly more and more difficu lt to rep lace vehicle
light bulbs since in many cases, ot her parts of the car must first be
removed before you are able to get to the bu lb. This app lies espec ially
to the l igh t bu lbs in the front of your car whi ch you can o nly rea ch
through the engine compartment .
Sheet metal and bu lb holders can have sharp edges that can ca use
serious cuts, and parts must be correctly taken apart and the n prop­
erly put back together to he lp prevent b reakage of parts and long
term damage from wate r that can enter housings that have not been
p roperly resealed.
For your safety, we recommend that you have you r authorized Audi
deale r replace any bu lbs fo r you, since your dealer has the proper
too ls, the cor rec t bu lbs and the expertise .
Gas dis charge lamp s (Xenon lights)* :
Due to the high electrical voltage, have the bulbs replaced by a qual­
ified technician. Headlights with Xe non light can be iden tified by the
high voltage sticker.
