Low aspect ratio tires
Your Audi is factory-equipped with low aspect ra
tio tires . These tires have bee n thoroughly tested
and been selected specifically fo r yo ur model fo r
the ir supe rb pe rformance, road feel and handling
u nder a va riety o f drivi ng conditions. Ask yo ur au
thor ized Audi de aler for mo re det ail s.
The low aspect ratio of these tires is indica ted by
a numeral of
55 or less i n t he tire's si ze des igna
tion . Th e nu mera l represents the rat io of the
tire's sidewall he igh t in relation to i ts tre ad wid th
expressed in percentage. Convent iona l tires have
a height/wi dth ratio of 6 0 or mo re .
The performan ce of low-a spe ct-rati o tires i s par
ticularly sensitive to improper inflation pre s
sure . It is therefore important that low a spect
ratio tires are inflated to the specified p ressure
and that the inflation pressure is regularly
checked and maintained. Ti re pressures should
be checked at least once a month and always
before a long trip
c:> page 245.
What you can do to avoid tire and rim damage
Low aspect ratio t ires can be damaged more easi
ly by impact with potholes, curbs , gullies or
ridges on the road , par ticu la rly if the t ire is un
de rinflate d.
In order to m inim ize the occurrence of impact
damage to the t ires of your vehicle, we recom
mend that you observe the following precau
tions:
Wheels
- Always ma inta in recommended inflation pres
sures. Chec k your tire pressure every 2,000
m iles (3,000 km) and add a ir if necessa ry .
- Drive carefully on roads with potholes, deep
gu llies o r ridges. T he impact from dr iving
through or over such obstacles can damage
your tires. Impact with a curb may also cause damage to your tires.
-After any impact, immed iate ly inspect your
tires or have them inspected by the nearest au
thorized Audi dealer . Replace a damaged t ire as
soon as poss ible .
- Inspect your tires every 2,000 m iles (3,000 km)
for damage and wear. Damage is no t always
easy to see . Damage can lead to loss o f air and
un derinflation, wh ic h could even tually caus e
t ire failure. If you believe tha t a tir e may have
been dam age d, rep lace the t ire as soon as pos
sible.
- These ti res may wear more quickly tha n oth ers.
- Please also remember that, wh ile these tir es

Wheels
Quality grades can be found where applicable on
the tire side wall between t read sho ulder and
maximum sect ion w idth
c::> page 235, fig . 204.
For example: Tr ead wear 200 , Tract ion AA, Tem
peratu re
A .
All passenger ca r tires must confo rm to Federal
Safety Req uiremen ts in add it ion to these grades.
Tread wear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
unde r controlled conditions on a spec ified gov
ernment test course.
For examp le, a t ire graded 150 would wear one
and one half ( 1 1/2) t imes as well on the govern
ment course as a tire graded 100 .
The relat ive performance of t ires depends upon
the actua l conditions of their use, however, and
may depart significantly from the norm due to
variations i n driving hab its, service practices and
d iffe rences in road character istics and clima te.
Traction
The traction grades, from highest to lowest, are
AA, A , Band
C. Those grades represent the tire's
ab ility to stop on wet pavement as measu red u n
de r controlled cond it ions on spec ified govern
ment test su rfaces of asphalt and concrete. A tire
marked C may have poor traction performance
c::> &_ .
Temperature
The temperature grades are A (the highest), B,
a nd C, rep resent ing t he tire's res istance to the
genera tion of heat and its a bility to dis sipate
heat w hen tested unde r controlled cond itions on
a specified indoo r laboratory test whee l.
Sustained high temperature can cause the mate rial of the tire to degenerate and red uce tire life,
a nd excessive tempera ture can lead to sudden
tire failure
c::> &. .
The grade C co rresponds to a level of perform
ance wh ich a ll passenge r ca r tires m ust meet un
de r th e Federal Motor Vehicle Safety S tandard
No. 109. G rades Band A represent higher levels
252
of pe rformance on the laboratory test whee l than
the minimum required by law .
A WARNING -
The traction grade assigned to th is tire is
based on straight-ahead braking tract ion
tests, and does not include acce lerat ion, cor
nering, hyd roplaning or peak traction charac
teristics.
A WARNING
The temperature g rade for th is tire is estab
lished for a tire that is properly inf lated and
n ot ove rloaded. Excess ive speed, underi nfla
tion, o r ex cess ive lo adi ng, eithe r separately or

Bulbs
Replacing light bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace burned out bulbs for you.
It is becoming increasingly more and more diffi
cult to replace vehicle light bulbs since in many
cases, other parts of the car must first be re
moved before you are ab le to get to the bulb.
This applies espec ially to the light bulbs in the
front of you r car which you can only reach
through the engine compartment.
Fuses and bulbs
Sheet metal and bulb holders can have sharp
edges that can cause serious cuts, and parts
must be correctly taken apart and then properly
put back together to help prevent breakage of
parts and long term damage from water that can
enter housings that have not been proper ly re
sealed .
For your safety, we recommend that you have
your authorized Aud i dealer replace any bulbs for
you, since your dealer has the proper too ls, the
correct bulbs and the expertise .
Gas discharge lamps (Xenon lights )*:
Due to the high e lectrica l voltage, have the bulbs
replaced by a qualified technician. Headlights
with Xenon light can be identif ied by the high
vo ltage sticker.
A WARNING
Contact with high-voltage components of the
electr ical system and improper replacement
of gas discharge (Xenon) headlight bulbs can
cause ser ious personal injury and death.
- Xenon bulbs are pressur ized and can ex-
plode when being changed.
- Changing Xenon lamps requ ires the special
train ing, instructions and equipment.
- Only an authorized Audi dealer or other
qualified workshop should change the bulbs
in gas discharge lamps.
A WARNING "'--
There are parts with sharp edges on the open-
in gs and on the bulb holders that can cause
serious cuts.
- If you are uncertain about what to do, have
the wor k performed by an authorized Aud i
dealer or other qualified workshop. Serious
personal injury may resu lt from improperly
performed work .
(D Tips
-If you must replace the light bulbs yourself,
always remember that the engine compart
ment of any vehicle is a hazardous area to
work in . Always read and heed all WARN
