torque must be checked as soon as possi­
ble with a torque wrench -preferably by an
author ized Audi dealer or qualif ied work­
shop.
Low aspect ratio tires
Your Aud i is factory-equipped with low aspect
ratio t ires . These t ires have been thoroughly
tested and been selected spec ifica lly for your
model for the ir superb pe rformance, road feel
and handling under a va riety of driving condi­
tions . Ask your a utho rized Aud i dea le r for
more detai ls.
The low aspect ratio of these ti res is indicated
by a numeral of
55 or l ess in the tire's size
des ignation. The numera l represents the rat io
of the tire's sidewall height in relation to its
tread width expressed in percentage. Conven­
tional tires have a height/width ratio of 60 or more.
The performance of low-a spe ct-ratio ti re s is
p articu lar ly sensi tive to imprope r inflat ion
pressure. It i s therefore impo rt a nt th at low
aspect r atio tire s are inflated to th e specified
pr essure and tha t th e inflation pres sure is
regularly checked and maintain ed . Tire pr es­
s ure s should be checked at l east once a
m onth and alway s befor e a long trip
~ page 241, Checking tire pressure.
What you can do to avoid tire and rim
damag e
Low aspect ratio t ires can be damaged more
eas ily by impact with potho les, cu rbs, gu llies
or ridges on the road, part icu larly if the t ire is
underinflated .
I n o rder to m inim ize the o ccu rrence of impact
damage to the tires of your vehicle, we recom­
mend that you observe the following precau­
tions:
- Always maintai n recommended i nflat io n
pressures. Check your tire pressure every
2,000 miles (3,000 km) and add a ir if neces­
sary . - Drive carefully 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, immed iate ly inspect your
tires or have them inspected by the nearest
author ized Audi dealer. Replace a damaged
tire as soon as possible .
- Inspect your tires every 2,000 m iles (3,000
km) for damage and wear. Damage is not al­
ways easy to see . Damage can lead to loss of
air and under inflation, which could eventu­
ally cause tire failure.
If you believe that a
t ire may have been damaged, rep lace the
t ire as soon as possible.
- These tires may wear more quickly tha n oth­
ers.
- Please also remember that, while these tires
de live r responsive hand ling, they may ride
less comfo rtably and make more noise than
other choices .
Reduced performance in winter /cold
season c onditions
All tires are designed for certa in p urposes.
T he low aspect ratio, ult ra h igh performance
t ir es originally insta lled on your vehicle are in ­
tended for maximum dry and wet road per­
formance and handling. They are not suitable
for cold, snowy or icy weather conditions. If
you drive under those c ircumstances, you
shou ld equ ip your vehicle with all-season or
winter tires, which offe r bette r traction unde r
those conditions. We sugges t you use the rec­
ommended snow or all -se ason t ires specified
f or yo ur vehicle , or their equivalent.
Refer to~
page 250 for more detailed infor­
mation regard ing winter tires.

Tire pressure monitoring system
UJ General notes
Applies to vehicles: with tire pressure monito ring system
Each t ire, i ncluding the spare (if provi ded),
should be chec ked month ly w hen cold and in­
flated to the inflation pressure recommended by the vehicle manufacture r o n the vehicle
placar d or tire infla tion pressure label. (If your
veh icle has t ires of a diff erent siz e than the
size ind icat ed on the vehicle p lacard or tir e in ­
flation pressure label, you should deter mine
the proper tire inflation pressure for those
tires).
As an added safety feature, your vehicle has been equipped with a tire pressure monitor ing
system (TPMS) that illuminates a low tire
pr essu re tellta le when one or mo re of your
tires is significantly under -inflated . Accord ing ­
l y, when the low tire p ress ure telltale illumi­
nates, you should stop and check your tires as
soon as possible, and inflate them to the
proper pressure. Driv ing on a signif icantly un­
der-inflated tire causes the tire to overheat
and can lead to tire failure. Under -inflation al ­
so reduces fuel efficiency and tire t read life,
and may affect the ve hicle's handling and
stopping ab ility.
Please note that the TPMS is not a subst itute
for p roper t ire mainte nance , and it is the dr iv­
e r's responsib ility to ma inta in cor re ct t ire
p ress ure, even if under- infla tion has no t
reached the leve l to trigger ill umin ation of the
TPMS low tire pressure telltale.
Your veh icle has also bee n equ ipped with a
TPMS malfunc tion indica to r to indica te when
the system is not opera ting properly. The
TPMS mal function indicato r is combined wi th
the low tire press ure tellta le . When the sys­
tem detects a malf unct ion, the te lltale will
flash for approximately one minute and then remain cont inuo usly illuminated. This se­
quence will continue upon subsequent vehicle
start-ups as long as the ma lf u nction ex ists .
Tire s an d wheel s 253
When the malfunction indicator is illum inat ­
ed , the system may not be ab le to detect or
s ignal low tire pressure as intended . TPMS
malfunctions may occur for a var iety of rea­
sons, including the insta llation of replace­
ment or alternate tires or wheels on the vehi ­
cle that p revent the TPMS from functioning
proper ly. Always check the TPMS malfunction
te lltale after rep laci ng one or more tires o r
whee ls on you r vehicle to e nsur e th at the re­
placement or alterna te t ires and wheels a llow
the TPMS to continue to func tion p roperly.

A WARNING
- If the tire pressure indicator appears in
the instrument cl uster display, one or
more of your tires is significantly under­
inflated. Reduce your speed immediately
and avoid any hard stee ring or braki ng
maneuvers. Stop as soon as possible and
check the t ires and the ir pressures. In­
flate the tire pres sure to the proper p res­
s u re as in dic ated on the vehicle 's t ire
pressure label ¢
page 238. Driving on a
significantly under-inf lated tire ca uses the tire to overheat and can
lead to tire
fa ilure. Under-inflation also is likely to
impair the vehicle's handling and stop­
ping ability.
- The driver is responsible for maintaining
the correct tire pressures. You must
check the tire pressures regu larly .
- Under certain conditions (such as a spor­
ty driving style, winter conditions or un­ paved roads), the pressure monitor indi ­
cato r may be delayed .
-Ask your authorized Aud i dea ler if run­
flat t ires may be used on you r vehicle.
Your vehicle registration becomes invalid
if you use these t ires when not perm it­
ted. Damage to your vehicle or accidents
could a lso result.
(D Tips
- The tire pressure mon itoring system
stops work ing whe n there is an ESC/ABS
m alfu nction.
- Us ing snow chains may result in a system
ma lf u nction.
- The tire pressure mon itoring system on
your Audi was deve loped using tires with

Replacing bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace any bulbs for you.
It is becoming increasingly more and more
difficult to replace vehicle light bulbs since in many cases, other parts of the car must first
be removed before you are able to get to the
bu lb. Thi s applies especially to the light bu lbs
in the front of your car which you can only
reach through the engine compartment .
Sheet metal and bulb holders can have sharp
edges that can cause ser ious cuts, 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 resealed.
F or your safety, we recommend that you have
your author ized Audi dealer replace any bulbs
for you, since your dealer has the proper tools,
the correct bu lbs and the expertise.
Ga s discharge lamps (Xenon lights}*:
Due to the high electrical vo ltage, have the
bu lbs rep laced by a qualified technician.
H eadlights with Xenon l ight are identified by
the high voltage sticker.
A WARNING
Changing Xenon lamps without the neces­
sary equipment can cause serious personal
in jury.
- Bulbs are pressurized and can explode
when being changed. Potential risk of in­
jury!
- On vehicles equipped with gas discharge
bulbs (Xenon light)* life-threatening in­
juries can result from improper handling
of the high-voltage portions of such
lamps!
- Only your authorized Audi dealer or a
qualified workshop should change the
bu lbs in gas discharge lamps. There are
pa rts with sharp edges on the openings
and on the bulb holders that can cause
serious cuts. If you are uncertain about
what to do, have the work performed by
an author ized Audi dealer or other quali­
fied workshop. Ser ious personal injury
may result from improperly performed
work.
(D Tips
- If you st ill prefer to replace the light
bulbs yourself, be aware that the engine
compartment is a hazardous area to
work in
9 page 213, Engine compart­
ment
9 Lr:,. .
-It is best to ask your authorized Audi
dealer whenever you want to change a
bulb.

2 7 4 Emergency situations
This might happen, for e xamp le, when
h eavy components such as the engine
b lock or transmiss io n are removed.
- When removing heavy components li ke
these, ancho r vehicle to ho ist o r add cor­
responding weig hts to ma inta in the cen ­
ter of g ravity . Othe rwise, the v eh icle
m ight tilt or slip
o ff th e hoist, caus ing
s er io us p ers on al inju ry.
(D Note
- Be awa re of the fo llowing points befo re
li fting the veh icl e:
- The vehicle should never be lifted or
jacked up from underneath the engine oil pan, the transmission housing , the
front or rear axle or the body side members. This could lead to serious
damage.
- To avoid damage to the underbody or
chassis frame, a rubber pad must be
inserted between the floor jack and
the lift points .
-Before driving over a workshop hoist,
check that the vehicle weight does not
exceed the permissible lifting capacity
of the hoist .
- Before driving over a workshop hoist,
ensure that there is sufficient clear­ ance between the hoist and low parts
of the vehicle.
