ro ll-overs.
A lwa ys rememb er: Airbags will deploy only o nce,
and on ly in certain kinds of coll is ions. Your safety
be lts are always there to offer protection in those
situations in which airbags are not supposed to
deploy, or when they have a lready deployed; for
examp le, when your vehicle str ikes or is struck by
another vehicle after the first collis ion.
This is just one of the reasons why an airbag is a
supp lementary restraint and is not a substitute
for a safety belt. The airbag system works most effect ively when used with the safety belts.
Therefore, always properly wear your safety belts
c::>page 176.
A WARNING
Sitting too close to the steer ing whee l or in­
st rument panel will decrease the effect ive­
ness of the airbags and will inc rease the risk
o f persona l injury in a co llision.
- Never sit closer than 10 inches (25 cm) to
the steering wheel or instrument panel.
- If you cannot sit mo re than 10 inches
( 2 5 cm) from the steering wheel, inves ti­
gate whethe r adaptive equipment may be
available to help you reach the pedals and
increase your seating distance from the
steering wheel.
- All veh icle occupants and especially children
must be restrained properly whenever riding
in a vehicle. An unrestrained or improperly
restra ined child could be injured by stri king
the inte rior or by being ejected from the ve­
hicle d uring a sudden maneuver or impact.
An unrestrained or imp roperly restrained
child is also at greate r risk of inju ry or death
through contact with an inflating airbag .
-If you are unrest rained, leaning fo rwa rd, s it­
t ing s ideways or o ut of pos ition in any way,
yo ur risk of in jury is mu ch h igher.
- Yo u will also receive serious injur ies and
c ou ld even be killed if you are up ag ainst the
airbag or too close to it w hen it inf lates -
even with an Advanced Ai rbag.
-
Airb ag sys tem
-To reduce the r is k of injury when an airbag
inflates, always wear sa fety belts prope rly
c::> page 179, Safety belts.
- Always make certain that children age 12 or
younger always ride in the rear seat. If chil­
dren are not properly restrained, they may be severely injured or killed when an airbag
inflates.
- Never let children r ide unrestrained or im­
p roperly restrained in the vehicle. Ad just the
front seats properly.
- Never ride with the back rest recl ined .
- Always sit as far as possible from the steer-
ing wheel or the instrument panel
c::> page 167.
- Always sit upright with your back against
the backrest of your seat .
- Never p lace your feet on the instrument
panel or on t he seat. Always keep both feet
on the floor in front of the seat to help pre­
vent ser ious injuries to the legs and hips if
the airbag inflates.
- Never recl ine the front passenger's seat to
transpo rt objects , Items can also mo ve in to
the area of the s ide a irbag or the front air­
b ag d uring braking o r in a sudden maneu­
ver. Obje cts ne ar the airbags can be come
p roject iles and cause injury when an airbag
inflates .
A WARNING ,.___ -
Airbags that have deployed in a crash m ust be
replaced.
- Use on ly original equipment airbags ap­
proved by A udi and installed by a t rained
technician who has the necessary tools and
d iagnostic equipment to properly replace
any airbag in yo ur vehicle and assure system
effect iveness in a crash .
- Never permit salvaged or recycled airbags to
be installed in your vehicle.

Airbag syste m
-Always make sure that there is nothing on
the front passenger seat that w ill cause the
capacitive passenger detection system in
the seat to signal to the Airbag System that
the seat is occupied by a person when it is
not, or to signa l that it is occupied by some­
one who is heav ier than the person actually
sitting on the seat. The p resence of addi­
tional objects could cause the passenger
front airbag to be turned on when it shou ld
be off, or could cause the airbag to work in a
way that is different from the way it would
have worked without the ob ject on the seat.
Front airbags
Description of front airbags
The airbag system can provide supplemental
protection to properly restrained front seat occu­
pants.
F ig. 163 Location of driver airbag: in steering wheel
Fi g. 16 4 Locatio n of front passenger 's airbag: in the in·
strument panel
Your vehicle is equipped with an "Advanced Air ­
bag System" in comp liance with United States
Federa l Motor Vehicle Safety Standard
(FMVSS) 208, as well as Canada Motor Vehicle
Safety Standard (CMVSS) 208 as applicable at
188
the time your vehicle was manufactured. T he
safety belts for the seats have "pretensioners"
that he lp to take s lack out of the belt system .
The pretensioners are also activated by the elec­
tronic control unit for the airbag system.
The front safety belts also have load limiters to help reduce the forces applied to the body in a
crash.
The airbag for the driver is in the stee ring wheel
hub
~ fig. 163 and the airbag for the front pas­
senger is in the instrument pane l
~fig. 164 . The
general locat ion of the airbags is marked "AIR­
BAG" .
There is a lot you need to know abo ut the airbags
i n your vehicle . We urge you to read the detai led
information about airbags , safety belts and ch ild
safety in this and the other chapters that make
up the ow ner's literature . Please be sure to heed
the WARNINGS -they are extremely important
fo r your safety and the safety of your passengers,
especially i nfants and small children .
.&, WARNING
-
Never rely on a irbags alone for prote ct io n.
- Even when they deploy, airbags p rovide only
supp lemental protection.
- Airbag work most effec tively when used
wit h properly worn safety be lts .
- Therefo re, always wear your safety be lts and
make sure that everybody in your veh icle is
properly restrained.
- Always hold the steering wheel w ith both
hands on the outside o f the steer ing whee l
rim at the 9:00 o'clock and 3:00 o'clock po­
si tions to help reduce the risk of personal i n­
jury if the driver's a irbag inflates.
- Never hold the stee ring wheel at the 12
o 'clock posi tion or with your hands any ­
where inside the steering wheel o r on the
steer ing whee l hub. Holding the steeri ng
wheel the wrong way increases the r isk of
severe injury to the arms, hands, and head if
the driver airbag deploys. .,,.

0 > co ,...., A WARNING
Objects between you and the airbag will in­
crease the risk of injury in a crash by interfer­
ing with the way the airbag unfolds and/or by
being pushed into you as the airbag inflates.
-Always make sure nothing is in the front air -
bag deployment zone that could be struck
by the airbag when it inflates .
- Objects in the zone of a deploying airbag
can become projectiles when the airbag de­
ploys and cause serious personal injury.
- Never hold things in your hands or on your
lap when the vehicle is in use .
-
-Never place accessories or other objects
(such as cup holders, telephone brackets,
note pads, navigation systems, or things
that are large, heavy, or bulky) on the doors;
never attach then to the doors or the wind­
shield; never place them over or near or at­
tach them to the area marked ,,AIRBAG" on
the steering wheel, instrument panel or the
seat backrests; never place them between these areas and you or any other person in
the vehicle .
- Never attach objects to the windshield
above the passenger front airbag, such as
accessory GPS navigation units or music players. Such objects could cause serious in­
jury in a collision, especially when the air­ bags inflate .
- Never recline the front passenger seat to
transport objects. Items can also move into
the deployment area of the side airbags or
the front airbag during breaking or in a sud­ den maneuver. Objects near the airbags can
fly dangerously through the passenger com­
partment and cause injury , particularly
when the seat is reclined and the airbags in­
flate.
A WARNING
A person on the front passenger seat, espe­ cially infants and small children, will receive
serious injuries and can even be killed by be­
ing too close to the airbag when it inflates.
- Although the Advanced Airbag System in
your vehicle is designed to turn off the front
Airbag system
passenger airbag if an infant or a small child
is on the front passenger seat, nobody can
absolutely guarantee that deployment un­
der these special conditions is impossible in
all conceivable situations that may happen
during the useful life of your vehicle .
- The Advanced Airbag System can deploy in accordance with the .,low risk" option for 3-
and 6-year-old children under the U.S. Fed­
eral Standard if a child with electrical capac­
itance greater than the combined capaci­
tance of a typical one-year old infant re­
strained in one of the forward facing or rear­
ward-facing child seats with which your ve­
hicle was certified is on the front passenger
seat and the other conditions for airbag de­
ployment are met .
- Accident statistics have shown that children
are generally safer in the rear seat area than
in the front seating position.
- For their own safety, all children, especially
12 years and younger, should always ride in
the back properly restrained for their age
and size.
Advanced front airbag system
Your vehicle is equipped with a front Advanced
Airbag System in compliance with United States
Federal Motor Vehicle Safety Standard 208 , as
well as Canada Motor Vehicle Safety Standard (CMVSS) 208 as applicable at the time your vehi­
cle was manufactured.
The front Advanced Airbag System supplements
the safety belts to provide additional protection
for the driver's and front passenger 's heads and
upper bodies in frontal crashes. The airbags in­
flate only in frontal impacts when the vehicle de­
celeration is high enough.
The front Advanced Airbag System for the front seat occupants is not a substitute for your safety
belts. Rather, it is part of the overall occupant re­
straint system in your vehicle. Always remember
that the airbag system can only help to protect
you, if you are sitting upright, wearing your safe­
ty belt and wearing it properly . This is why you
and your passengers must always be properly .,..

Airbag syste m
restrained, not just because the law requires you
to be.
The Advanced Airbag System in your veh icle has
been cert ified to meet the "low r isk" require­
ments for 3 and 6 year-o ld children on the pas­
senger side and very sma ll adults on the driver
side . The low risk dep loyment cr iteria are intend­
ed to he lp reduce the risk of injury through inter­
action with the front airbag that can occur, for
example, by being too close to the steering wheel
a nd instrument panel when the airbag inflates .
In addition, the system has been certified to
comply w ith the "suppression" requirements of
the Safety Standard, to turn off the front a irbag
for i nfants 12 months old and younger who a re
restrained on the front passenger seat in ch ild re­
stra ints that are listed in the Standa rd
¢ page 211, Child restraints and Advanced front
airbag system.
" Suppression" requ ires the front a irbag on the
passenger side to be tu rned off if:
- a child up to about one year of age is restra ined
o n the fro nt passenger seat in one of the rear­
facing or forward-facing infant restraints listed
in Federal Motor Vehicle Safety Standard 208
with wh ich the Advanced Airbag System in your
vehicle was certified. For a listing of the ch ild
restraints that were used to certify your vehi ­
cle's compliance with the US Safety Standard
¢ page 211,
-When a person is detected on the front passen­
ger seat that has an electrica l capacitance t hat
is more than the tota l electrical capacitance of
a chi ld that is about 1 year old restrained in one
of the rear-facing or forward-fac ing infant re­
straints (listed in Federal Motor Vehicle Safety
Standard 208 w ith w hich the Advanced A irbag
System in your veh icle was certified), the front
airbag on the passenge r side may or may not
deploy.
The
P ASS ENGER AIR BAG OFF light comes on
when the e lectron ic cont rol un it detects a total
e lectr ica l capacitance on the front passenger seat
that requires the front a irbag to be turned off. If
the
PAS SENGER AIR BAG OFF light does not
come on, the front airbag on the passenger side
190
has not been turned off by the contro l uni t and
can deploy if the contro l unit senses an impact
that meets the cond itions stored in its memory.
If the total e lectr ica l capacitance registered o n
the front passenger seat is more than that of a
typica l 1 year-old, but less than the weight of a
small adu lt, t he front a irbag on the passenger
s ide may deploy (the
PA SS ENGER AIR BAG OFF
light does not come on).
For e xample , the ai rbag ma y deplo y if:
- a small ch ild that is heav ier than a typica l 1
year-old child is on the front passenger seat
(regard less o f whether the child is in one o f the
child seats listed
¢ page 211),
-a child who has outgrown child restraints is on
the front passenger seat.
If the front passenger a irbag is t urned off, the
PA SSENGER AIR BAG O FF light in the center of
the instr ument pane l will come on and stay on .
If the front passenger a irbag deploys, the Feder­
al Standard requ ires the airbag to meet the "low
r isk" dep loyment criteria to he lp reduce the r isk
of inju ry through interaction with the airbag .
"Low risk" deployment occurs in those crashes
that take p lace at lower decelerations as defined
in the electronic contro l unit ¢
page 196.
Alwa ys remembe r: Even though your vehicle is
equipped with Advanced Airbags, the safest place
for children is properly restrained on the back
seat. Please be sure to read the important infor­
mation in the sections that fo llow and be sure to
heed all of the WARNINGS.
A WARNING
To reduce the risk of injury when an airbag in­
flates, always wea r safety belts prope rly.
- If you are unrestrained, leaning forward, sit­
ting sideways or out of position in any way,
your r isk of injury is much highe r.
- You will also receive ser ious injuries and
could even be killed if you are up against the
airbag or too close to it when i t inflates -
even with an Advanced Airbag

Airbag syste m
-An Advanced Airbag with gas generator for the
driver inside the steering wheel hub .
- An Advanced Airbag with gas generator ins ide
the instr ument pane l for the front passenger.
- A capacitive passenger detect io n system unde r­
neath the front passenger seat cover . This sys­
tem measures the electrical capacitance of the person in th e seat. The information registered
is sent continuously to the electron ic control
unit to regula te deployment of the front Ad­
vanced Airbag on the passenger s ide .
- An airbag monitoring system and indicator
light in the instrument cluster
¢ page 196.
-A sensor in each front seat registers the dis­
tance between the respective seat and the
steering wheel or instrument panel. The infor­
mation reg istered is sent continuously to the
electronic control un it to regulate deployment
of the fro nt Advanced A irbags.
- The
PASSENGER AIR BA G OFF light comes on
and stays on in the center of the instrument
panel ¢
page 236 and tells you when the front
Advanced Airbag on the p assenge r side has
been turned off .
- A sensor in the safety belt la tch for the driver
and for the front seat passenger that senses
whethe r that safety belt is latched or not and
transmits this information to the electronic contro l unit.
.&_ WARNING
Damage to the front passenger seat can pre­
vent the front airbag from working properly.
- Improper repa ir or disassemb ly of the front
passenger and driver seat w ill prevent the
Advanced Airbag System from functioning properly .
- Repairs to the front passenger seat must be
performed by qua lified and prope rly trained
workshop personnel.
- Never remove the front passenger or dr iver
seat from the vehicle.
- Never remove the upho lstery from the front
passenger seat.
- Never disassemble or remove parts from the
seat or disconnect wires from it.
192
- Never carry sharp objects in your pockets or
put them on the seat. The capacit ive pas­
senger detection mat in the front passenger
seat will not function properly if it is punc­
tured .
- Never carry things on your lap or carry ob­
jects on the front passenger seat . Such ob­
jects ca n influence the capacitance regis­
tered by the capacitive passenger detection
sys tem, so tha t incorrect informat io n is pro­
vided to the a irb ag cont rol unit.
- Never store items under the front passenger
se at. Parts of the Advanced Airbag System
un der the passenger seat could be dam­
aged, p reventing them and the airbag sys ­
tem from wor king p roper ly .
- Never p lace seat covers or replacement up­
holstery that have not been specifically ap­
proved by Audi on the front seats .
- Seat covers can prevent the Advanced A ir­
bag System from recognizing chi ld re­
straints or occupants on the front passenger
seat and prevent the side airbag in the seat
backrest from deploying properly.
- If a seat heater has been retrofitted or oth­
erwise added to the front passenger seat,
never install any child restra int system on
this seat.
- Never use cushions, p illows, blankets, or
sim ila r items o n the front passenger seat .
The additional layers prevent the capacit ive
passenge r detection sys tem from accurately
measuring the capacitance of the child safe­
ty seat and/or the person on the sea t and
t hus keep the Advanced A irbag System from
wo rking properly.
- Never p lace or use any e lectr ic al device
(such as a lap top, CD player, e lectronic
games device , power inve rter or seat heater
for child seats) on the front passenger seat if the device is connected to the 12 -volt
socket or the cigarette lighte r socket. Such
dev ices can influence the capac itance regis­
tered by the capaci tive passenger detection
system, so that incorrect informat io n is pro-
vided to the airbag cont rol unit.

backrest, center armrest, door or roof.
- Always install rear-facing child seats on the
rear seat.
- If you must install a rearward facing child
seat on the front passenger seat because of
exceptional circumstances and the
PASSEN­
GER AIR BAG OFF
light does not come on
and stay on, immediately install the rear­
facing child seat in a rear seating position
and have the airbag system inspected by
your Audi dealer.
A WARNING
Objects between you and the airbag will in­
crease the risk of injury in a crash by interfer­
ing with the way the airbag unfolds or by be­
ing pushed into you as the airbag inflates.
- Never hold things in your hands or on your
lap when the vehicle is in use.
- Never transport items on or in the area of
the front passenger seat . Objects could
move into the area of the front airbags dur­
ing braking or other sudden maneuvers and
become dangerous projectiles that can
cause serious personal injury if the airbags
inflate.
- Never place or attach accessories or other objects (such as cup holders, telephone
brackets, large, heavy or bulky objects) on
the doors, over or near the area marked "AIRBAG" on the steering wheel, instru­
ment panel, seat backrests or between
those areas and yourself. These objects
could cause injury in a crash, especially
when the airbags inflate.
- Never recline the front passenger's seat to
transport objects. Items can also move into
the area of the side airbag or the front air­ bag during braking or in a sudden maneu­
ver. Objects near the airbags can become
projectiles and cause injury, particularly
when the seat is reclined.
- Never place or transport objects on the front passenger seat. Objects on the front passenger seat could cause the capacitive
sensor in the seat to signal to airbag system
Airbag system
that the seat is occupied by a person when it
in fact is not, or that the person on the seat
is heavier than he or she actually is. The
change in electric capacitance because of
such objects can cause the passenger front
airbag to be turned on when it should be
off, or can cause the airbag to work in a way
that is different from the way it would have
worked without objects on the seat.
- Always make sure that there is nothing on
the front passenger seat that will cause the
capacitive passenger detection system in
the seat to signal to the Airbag System that
the seat is occupied by a person when it is not, or to signal that it is occupied by some­
one who is heavier than the person actually
sitting on the seat. The presence of an ob­
ject could cause the passenger front airbag to be turned on when it should be off, or
could cause the airbag to work in a way that is different from the way it would have
worked without the object on the seat.
_LD. WARNING
The fine dust created when airbags deploy can cause breathing problems for people with a
history of asthma or other breathing condi­
tions.
- To reduce the risk of breathing problems,
those with asthma or other respiratory con­
ditions should get fresh air right away by
getting out of the vehicle or opening win­
dows or doors.
- If you are in a collision in which airbags de­ ploy, wash your hands and face with mild
soap and water before eating .
- Be careful not to get the dust into your eyes,
or into any cuts or scratches.
- If the residue should get into your eyes, flush them with water .

Repair, care and disposal of the airbags
Pa rts of t he air bag system are i nstalled at many
d ifferen t places on your Aud i. Insta lling , remov­
ing, servi cing or repa iring a part in an area of the
ve hicle can damage a part of an airbag system
and prevent that system from working properly
in a co llision .
There are some important things you have to
know to mak e sure that the effectiveness of the
system wi ll not be impaired and that discarded
components do not cause injury or poll ute the
env ironment.
A WARNING
Improper care, serv icing and repa ir proce­

Although they are not a soft pillow, they can
"cushion" the impact and in this way they can
he lp to reduce the risk of injury to the lower ex­
tremities .
All of this takes place in the blink of an eye, so
fast that many people don't even realize that the airbags have deployed. The a irbags also inflate
with a great deal of force and it is important for
occupant safety that nothing should be in their
way when they deploy .
Fully inflated airbags in comb ination with proper­
ly worn safety belts slow down and limit the oc­
cupant's forward movement and help to reduce
the risk of inju ry.
Important safety instructions on the knee
airbag system
App lies to veh icles : with knee a irbags
Airbags are only supplemental restraints . Always
wear safety belts correctly and ride in a proper
seating position.
There is a lot that you and your passengers must
know and do to help the safety belts and airbags
to provide supplemental protection .
,&. WARNING
An inflating knee airbag can cause ser ious in ­
jury. Wearing safety bel ts incorrectly and im­
proper seating positions increase the r isk of
serious personal injury and death whenever a
vehicle is being used.
- The knee airbag system cannot protect you properly if you are seated too close to any of
the airbag locat ions. When adjusting their
seat positions, it is important that both the driver and the front passenger keep their
upper bodies and knees at the following
min imum safe distances:
- at least 10 inches (25 cm) between the
chest and the steering wheel/instrument panel.
- at least 4 inches (10 cm) between the
knees and the lower part of the instru­ ment panel.
- The risk of persona l injury increases if you
lean forward or to the s ide, or if the seat is
202
improperly positioned and you are not wear­
ing your safety belt. The risk increases even
more should the airbag deploy.
- Always make sure that the knee a irbag can
inflate w ithout interference. Objects be­
tween you and the airbag can increase the
r isk of injury in an accident by interfering
w ith the way the airbag deploys or by being
pushed i nto you as the a irbag deploys.
- Never let anybody, especia lly children or
anima ls ride in the footwell in front of the
passenger seat. If the airbag deploys, this
can result in serious or fatal injuries .
- Never carry objects of any kind in the foot ­
well area in front of the driver's or pas­ senger's seat. Bulky objects (shopp ing
bags, for example) can interfere with or
prevent proper dep loyment of the a irbag.
Small objects can be thrown through the
vehicle if the airbag deploys and injure you
or your passengers.
- Ma ke sure there are no crac ks, deep scratch­
es o r other damage in the area of the i nst ru­
ment panel where the knee airbags are lo ­
cated .
- If children are incorrec tly seated, their risk
of injury increases in a coll is ion

0 > co ,...., Advanced front airbag system and children
Your vehicle is equipped with a front "Advanced
Airbag System" in compliance w ith United States
F edera l Motor Vehicle Safety Standard ( FMVSS)
208, as well as Canada Motor Vehicle Safety
Standard (CMVSS) 208 as applicable at the time
your veh icle was manufactured.
The Advanced Airbag system in your vehicle has been certified to meet the "low-risk" require ­
ments for 3- and 6-year old children on the pas­
senger side and small adults on the driver side.
The low risk deployment criteria are intended to
reduce the risk of injury through interaction with
the airbag that can occur, for example, by being
too close to the steering wheel and instrument panel when the airbag inflates. In addition, the
system has been certified to comply with the
"s uppress ion " req uirements of the Safety Stand­
a rd, to turn off the front ai rbag for infants up to
12 months who are restrained on the front pas­
senger seat in child restraints that are listed in
the Standard.
E ven though your vehicle is equipped with an Ad ·
vanced Airbag system, all children, especially
those 12 years and younger, should always ride
in the back seat properly restra ined for their age
and si ze. The airbag on the passenger side makes
the front seat a potentially dangerous place for a
child to r ide . The front seat is not the safest place
for a child in a forward-facing child safety seat .
It
can be a very dangerous place for an infant or a
l arger child in a rearward -facing seat.
The vehicle's Advanced A irbag System has a ca ­
pac itive passenger detect io n system in the front
passenger seat cush ion that can detect the pres­
ence of a baby or a child in a ch ild restraint sys­
tem on this seat .
The capacit ive passenger detection system regis­
ters the changes that result in an electrical fie ld
when a ch ild, a child restra int, and a baby blanket
are on the front passenge r seat. The change in
the measured capacitance due to the presence of
a child, a child restraint, and a baby b lanket on
the front passenger seat is related to the child restraint system resting on the seat. The meas­
ured capacitance of a child restraint system var-

make and mode l.
T he elect rical capac itance of the va rious types,
makes, and models of chi ld restra ints specified
by the U.S .National Highway Traff ic Safety Ad­
ministration (NHTSA) in the relevant safety
standard are stored in the Advanced Airbag Sys­
tem control unit together with the capacitances
typ ical of infants and a 1-year old child. When a
child restraint is used on the front passenger
seat w it h a typical 1 year-old infant, the Ad­
vanced Airbag System compares the capacitance measured by the capacitive passenge r detection
system with the data stored in the electronic co n­
t rol unit.
Child restraints and Advanced front airbag
system
Regardless of the ch ild restraint that you use,
make sure that it has been certified to meet Safe­
ty Standards and has been cert ified by its manu ­
facturer for use w ith an airbag . Always be sure
that the c hild rest raint is p roperly installed at
one of the rear seating positions . If in exception­
al circumstances you must use it on the front
passenge r seat, carefu lly read a ll of the informa­
tion on child safety and Advanced Airbags and heed all of the applicable WARNINGS . Make cer ­
tain that the chi ld and child restraint are correct­
ly recognized by the capac itive passenger detec­
t ion system in the front passenger seat, that the
front passenger a irbag is turned off, and that the
airbag status is always correctly s ignaled by the
PASSENGER AIR BAG OFF light .
Many types and models of child restra ints have
been available over the years, new models are in ­
troduced regu larly incorporating new and im­
proved designs and older models a re take n out of
production. Child restra ints are no t standa rdized.
Child res tra ints of the same type typically have
different weights and sizes and different "foot­
prints", the size and shape of the bottom of the
chi ld restraint that sits on th e seat, when they
are installed on a vehicle seat. These d ifferences
make it virtually impossib le to certify compliance
with the requirements for advanced a irbags w ith

Tires and wheels
-Have an authorized Audi dealer or authorized Audi Service Facili­
ty check the wheel alignment if
there is unusual wear .
-Have the wheels rebalanced if an imbalance is causing noticeable
vibration in the steering wheel. If you do not, the tires and other
vehicle components could wear more quickly.
Treadwear indicator
Original equipment tires contain
treadwear indicators in the tread pattern, which are bars that are 1/16 in. (1.6 mm) high and are
spaced evenly around the tire per­
pendicular to the running direc­
tion
¢ fig . 203 . The letters "TWI"
or triangles on the tire sidewall indicate the location of the tread­
wear indicators.
The tires have reached the mini­ mum tread depth
l) when they
have worn down to the tread wear
indicators. Replace the tires with
new ones

Wheel rotation

wear evenly. To rotate wheels, in­
stall the wheels from the rear
axle on the front axle and vice
versa . This will allow the tires to
have approximately the same
length of service life.
For unidirectional tires, make
sure the tires are installed accord­
ing to the running direction indi­
cated on the tire sidewall
¢page 288.
Hidden damage
Damage to tires and rims can of­
ten occur in locations that are hidden . Unusual vibrations in the
vehicle or pulling to one side may indicate that there is tire damage.
Reduce your speed immediately.
Check the tires for damage . If no
damage is visible from the out­
side, drive slowly and carefully to
the nearest authorized Audi deal­
er or authorized Audi Service Fa­
cility to have the vehicle inspect­
ed .
.&_ WARNING
Tread that has worn too low or
different tread depths on the
tires can reduce driving safety. ,..
