Airbag syste m
also not inflate in side or rear co llisions, or in
ro ll- overs.
Alwa ys rem ember : Airbags will deploy only once,
and on ly in ce rtain k inds of coll is ions. Yo ur safety
be lts are always there to offer protection in those
situations in which airbags are not supposed to
deploy, or when they have already deployed; for
examp le, when your vehicle str ikes or is struck by
another vehicle after the first collision.
This is just one of the reasons why an airbag is a
supplementary restraint and is not a substitute
for a safety belt. The a irbag system works most
effect ively when used with the safety belts.
Therefore, always properly wear your safety belts
r;:;, page 260 .
A WARNING
Sitting too close to the steering wheel o r in­
st rument panel will decrease the effective­
ness of the airbags and will inc rease the risk
of personal injury in a co llision.
- Never sit closer than 1 0 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, invest i­
gate whether adaptive equipment may be
available to help yo u reach the pedals and
increase your seating distance from the
steering wheel.
- All vehicle occupants and especially children
must be restrained properly whenever riding
in a vehicle. An unrestrained or improperly
restra ined child could be injured by striking
the interior or by being ejected from the ve­
hicle during 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 infla ting airbag .
-If you are unrestrained, leaning fo rwa rd, s it­
t ing s ideways or o ut o f pos ition in any way,
yo ur risk of in ju ry is much h igher.
- Yo u will also receive serious injuries and
could even be killed if you are up aga inst the
air bag or too close to it when it inflates -
even with an Advanced Airbag.
270
-
- To reduce the r is k of i njury when an a irbag
inflates, always wear safety belts prope rly
r;:;, page 264, Safety belts.
- Always make certa in that children age 12 or
younge r 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 ch ildren r ide unrestra ined or im­
properly 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
r;:;, page 250 .
-Always sit upright w ith your back against
the backrest of your seat .
- Never p lace your feet on the instrument
panel or on the seat . Always keep both feet
on the floor in front of the seat to help pre­
vent serious injur ies to the legs and hips if
the airbag inflates.
- Never recl ine the front passenger's seat to
transpo rt objects . Items can also move into
the area of the s ide airbag or the front air­
bag du ring brak ing o r in a sudden maneu­
ver . Obje cts nea r the airbags can become
pro jecti les 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 Audi and installed by a trained
technician who has the necessary tools and
diagnostic equipment to properly replace
any airbag in yo ur vehicle and assure system
effectiveness in a crash.
- Never perm it salvaged or recycled airbags to
be installed in your vehicle .

-An improper ly installed child restraint can
interfere with the airbag as it deploys and
seriously injure or even kill the child
-even
with an Advanced Airbag System.
- Always carefully follow the manufacturer's
instructions provided with the child seat or
carrier .
- Always make sure that there is nothing on
the front passenger seat that will cause the capacit ive 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 addi­
tional objects 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 .
Front airbags
Description of front airbags
The airbag system can provide supplemental
protection to properly restrained front seat occu­
pants.

Your vehicle is equipped with an "Advanced Air­
bag System" in compliance with United States
Federal 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 airbag for the driver is in the steering wheel
hub
¢ fig. 236 and the airbag for the front pas­
senger is in the instrument panel
¢fig . 237. The
general location of the airbags is marked "AIR­
BAG ".
There is a lot you need to know about the airbags
in your vehicle . We urge you to read the detailed
information about airbags, safety belts and child
safety in this and the other chapters that make
up the owner's literature. Please be sure to heed
the WARNINGS
-they are extremely important
for your safety and the safety of your passengers,
especially infants and small children.
_& WARNING
-Never rely on airbags alone for protection .
- Even when they deploy, airbags provide only
supplemental protection.
- Airbag work most effectively when used
with properly worn safety belts.
- Therefore, always wear your safety belts and
make sure that everybody in your vehicle is
properly restrained.
- Always hold the steering wheel with both
hands on the outside of the steering wheel
rim at the 9:00 o'clock and 3:00 o'clock po­
sitions to help reduce the risk of personal in-
jury if the driver's airbag inflates.

Airbag syste m
-Never hold the steering whee l at the 12
o'clock pos it ion or w ith your han ds any­
where inside the steering wheel or on the steering wheel hub. Holding t he steering
wheel the wrong way increases the risk of severe injury to the arms, hands, and head if
the d river a irbag deploys.
A WARNING
Objects between you and the a irbag w il l in­
crease the risk of inj ury in a crash by interfer­
ing w ith the way the airbag unfo lds 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 str uck
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 persona l injury .
- Never hold th ings in your hands or on your
lap when the vehicle is in use.
- Never place accessor ies or other objec ts
(s uch as c up ho lders, telephone brackets,
note pads, navigation systems, or things
that are large, heavy, o r 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 p lace them between
these a reas and yo u or any other person in
the vehicle.
- Never attach objects to the w indshield
above the passenger front airbag, s uch as
accessory GPS navigation uni ts or mus ic
players . S uch objects could ca use serio us 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 a irbags or
the front a irbag during breaking o r in a sud­
den maneuver. Objects near the airbags can
fly dangerous ly through the passenger com­
partment and cause injury, particularly
when the seat is reclined and the airbags in­
flate.
274
A WARNING
A person on the front passenger seat, espe­
cially infants and small ch ildren, wi ll receive
serious in juries and can even be k illed by be­
ing too close to the airbag when it inflates .
- Although the Advanced Airbag System in your veh icle is designed to turn off the front
passenger airbag if an infant o r a small child
is on the fron t passenger sea t, nobody can
absolu tely guarantee tha t deployment un­
de r these specia l condi tions is impossible in
all conceivable situations that may happen
during the useful life of yo ur vehicle.
- The Advanced Airbag System can dep loy in
accordance with the
,. low risk" option for 3-
and 6-year-old children under the U.S. Fed­
eral Standard if a child w ith electrical capac­
itance greater than the combined capac i­
tance of a typical one-year o ld infant re­
strained in one of the forward facing or rea r­
ward-facing chi ld seats with which yo ur ve­
hicle was certified is on the front passenger
seat and the o ther conditions for airbag de-
ployment are me t.
- Accident s tatisti cs have shown th at children
are generally safer in the rear seat are a than
in the front seat ing pos ition.
- For their own s afety, all ch ildren, especi ally
12 years and younger, should alw ays ride in
the back proper ly 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 Veh icle Safety Standard
(CMVSS) 208 as applicable at the t ime your vehi­
cle was manufactu red .
The front Advanced A irbag System supplements
the safety belts to provide add itiona l protect ion
for the driver 's and front passenger's heads and
upper bod ies in fronta l crashes. The a irbags in­
flate only in frontal impacts when the vehicle de-
ce le ra tion is high e no ugh.

The front Advanced Airbag System for the front
seat occupants is not a substitute for your safety
be lts. Rather, it is part of the overa ll occupant re­
stra int system in your vehicle. A lways remember
that the airbag system can on ly help to protect
you, if you are sitting upr ight, wear ing your safe­
ty belt and wear ing it properly . This is why you
and your passengers must always be prope rly re­
stra ined, not just beca use the law req uir es yo u to
be.
The Advanced Airbag System in your ve hicle has
been ce rt ified to meet the " low r isk" requ ire­
ments fo r 3 and 6 yea r-o ld children o n the pas­
senger side and very sma ll adul ts on the d rive r
side . The low r is k dep loymen t cr iteria are intend ­
ed to he lp reduce t he ris k of injury through inter­
action with the front airbag that can occ ur, for
examp le, by being too close to the steering whee l
and instrument pane l when the airbag inflates .
I n addition, the system has been certified to
comp ly with the "suppression" requirements of
the Safety Standard, to t urn off the front a irbag
for infants 12 months old and younger who are
restrained on the front passenger seat in c hild re­
stra ints that are listed in the Standard
<=:> page 297, Child restraints and Advanced front
airbag system.
"Suppress ion" requ ires the front a irbag on the
passenger side to be turned
off if:
- a ch ild up to about one year of age is restra ined
on the front passenger seat in one of the rear­
facing or forward-fac ing infant restra ints listed
in Federal Motor Vehicle Safety Standard 208
with wh ic h the Advanced Airbag System in your
vehicle was ce rt ified. For a listing of the c hild

a chi ld that is about 1 year old restrained in one
of the rea r-facing or forward-facing infant re ­
straints (listed in Federal Motor Vehicle Safety Standard 208 w ith which the Advanced A irbag
System in your ve hicle was certified), the front

airbag on the passenger side may or may not
dep loy.
T he
PASSENGER AIR BAG OFF lig ht comes o n
whe n the elect ronic con trol uni t detec ts a t otal
electrica l capacitance on the front passenger seat
t h at requires the front airbag to be turned
off . If
t h e
PASSENGER AIR BAG OFF light does not
come on, the front airbag on the passenger side
has not been turned
off by the contro l unit and
can deploy if the contro l unit senses a n impact
t h at meets the cond it ions stored in its memory .
If the total electr ica l capacitance reg istered o n
the front passenger seat is more t han that of a
typ ical 1 year-old , but less than the weight of a
small ad ult, the front a irbag on the passenger
s ide may dep loy (the
PASSENGER AIR BAG OFF
li ght does not come on) .
For example, the airbag may deploy if :
-a small ch ild that is heav ier than a typ ica l 1
year-o ld child is on the front passenger seat
(regardless of whether the child is in one of the
child seats listed
¢ page 297),
- a child who has outgrown c hild rest raints is on
the front passenger seat.
If the front passenge r ai rbag is t urned off, the
PASSENGER AIR BAG OFF light in the center of
the instr ument pane l will come on and stay on.
If the front passenge r airbag deploys, the Feder ­
al Standard requi res t he airbag to meet the " low
risk" deployment criteria to he lp reduce the r is k
of i njury through interaction with the a irbag.
"Low risk" deployment occurs in those crashes
t h at take place at lower decelerations as defined
i n t he electron ic co ntro l
unit ¢ page 281 .
Always remember : Even though your vehicle is
equipped with Advanced Airbags, the safest place
for ch ildre n is properly restra ined o n the back
seat . Please be s ure to read the impo rtant in for­
mation in the sect ions that fo llow a nd be sure to

Airbag System for the front passenger seat from
doing its job in a crash.
The front Ad vanced Airbag System con sists
o f th e follo wing :
-Cras h sensors in the front of the vehicle that
measure vehicle acceleration/deceleration to
provide information to the Advanced Airbag
System a bout the severity of the crash.
- An electronic control unit, with integrated
crash sensors for front and side impacts. The
contro l unit "decides" whether to fire the front
airbags based on the information received from
the crash sensors . The control unit also "de­
c ides" whether the safety belt pretens ioners
shou ld be activated .
-An Advanced Airbag with gas generator for the
dr iver inside the steering wheel hub.
-An Advanced Airbag with gas generator ins ide
the instrument panel for the front passenger.
-A capac itive passenger detect io n system under­
neath the front passenger seat cover. This sys­
tem measures the elect rical capac ita nce of the
person in the seat. The info rmat ion registe red
is sent cont inuous ly to the electro nic cont rol

A WARNING
A child in a rearward-facing child seat instal­
led o n the front passenger seat will be ser i­
ously injured and can be k ille d if the front air­
bag in flate s - even with an Advanced Airbag
System.
- The inflating a irbag w ill hit the child seat or
infant carrier w ith great force and will
smash the ch ild seat and child against the
backrest, cente r arm rest, door or roof.
- Always install rear-facing child seats on the
rea r seat.
- If you must install a rearward fac ing ch ild
seat on the front passenger seat because of
exceptional c ircumstances and the
PASSEN­
GER AIR BAG OFF
light does not come on
and stay on, immediately insta ll 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 a irbag w ill in­
crease the risk of in jury in a crash by interfer­
ing w ith the way the airbag unfolds or by be­
ing pushed into you as the a irbag inflates.
- Never hold th ings in your hands or on your
lap when the vehicle is in use .
- Never transport items on or in the area of
the fron t passenger seat . Objects could
move into the area of the front airbags du r­
ing bra king or other sudden maneuve rs and
become dangerous projec tiles that c an
ca use serious pe rsonal injury if the a irbags
inflate.
- Never pl ace or attach accessor ies or o ther
objects (such as cup ho lders, te lephone
brackets, large, heavy or bulky objects) on
the doors, over or nea r the area marked
"AIRBAG" on the steering wheel, instru­
ment pane l, seat backrests or between
those areas and yourself. These objects could cause injury in a crash, especially
when the airbags infla te.
- Never recline the front passenger's seat to
transport objects . Items can also move into
the a rea of the side airbag o r the front a ir-
280
bag du ring brak ing o r in a sudden maneu­
ver. Objects near the airbags can become pro jecti les and cause injury, part icularly
when the seat is reclined .
- Never p lace 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 ai rbag system
that the seat is occ upied by a person when it
in fact is no t, or that the pe rson on the seat
is he avie r th an he or she act ually is. The
change in electric capacitan ce beca use of
such objects can cause the passenge r front
airbag to be turne d 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
wo rked without objects on the seat.
- Always make sure that there is noth ing on
the front passenger seat that will cause the
capacitive passenger detection system in
the sea t to signal to the Airbag System that
the seat is occup ied by a person when it is
not, or to signal that it is occupied by some­
one who is heavier th an the person actu ally
si tting on the sea t. The presence of an o b­
ject could ca use the passenger front air bag
to be turned on when it should be off, or
could cause the airbag to work in a way that is diffe rent from the way it would have
worked without the object on the seat.
A WARNING
The fine dust created when airbags deploy can
cause breathing prob lems for people with a
h istory of asthma or othe r breath ing cond i­
tions .
- To reduce the r isk of breathing p roblems ,
those wi th asthma o r other respiratory con­
ditions sho uld get fresh a ir rig ht away by
getting out of the vehi cle or opening win­
dows or doors.
- If you are in a co llision in which airbags de­
ploy, w ash yo ur hands and f ace with m ild
soap and water be fore eating.
- Be ca refu l not to get the dust into your eyes,
or into any cuts or scratches.
- If the residue sho uld get into your eyes,
flush them w ith wate r.

PLACEMENT RECORD.
- Applies to plug-in hybrid* vehicles: In the
event of a collision where the airbags de­
ploy, the electrical connection to the high
voltage battery is automatically disconnect­
ed. This prevents a short c ircuit.
@) For the sake of the environment
Undeployed airbag modules and pretension­
ers might be classified as Perchlorate Materi­
al - special handling may apply, see
www.dtsc.ca.gov/hazardouswaste/perchlo­
rate. When the vehicle or parts of the re­
straint system including airbag modules and
safety belts with pretensioners are scrapped,
all applicable laws and regulations must be
observed. Your authorized Audi dealer is fa­
miliar with these requirements and we recom­
mend that you have your dealer perform this
service for you.
Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag System
performs in a crash. For example, using tire-rim
combinations not approved by Audi, lowering the
vehicle, changing the stiffness of the suspension, including the springs , suspension struts, shock
absorbers etc. can change the forces that are
measured by the airbag sensors and sent to the
electronic control unit . Some suspension changes
can, for example, increase the force levels meas­
ured by the sensors and make the airbag system
deploy in crashes in which it would not deploy if
the changes had not been made. Other kinds of
changes may reduce the force levels measured by
the sensors and prevent the airbag from deploy­
ing when it should.
A WARNING
Changing the vehicle's suspension including
use of unapproved tire-rim combinations can
change Advanced Airbag performance and in-
.
Airbag system
crease the risk of serious personal injury in a
crash.
- Never install suspension components that
do not have the same performance charac­
teristics as the components originally instal­ led on your vehicle.
- Never use tire-rim combinations that have
not been approved by Audi.
Knee airbags
Description of knee airbags
Applies to: vehicles with knee airbags
The knee airbag system can provide supplemen­
tal protection to properly restrained front seat
occupants.
Fig. 240 Driver 's knee airbag
The driver knee airbag is in the instrument panel
underneath the steering
wheel¢ fig. 240, the
airbag for the passenger is at about the same
height in the instrument panel underneath the
glove compartment.
The knee airbag offers additional protection to
the driver's and passenger's knees and upper and
lower thigh areas and supplements the protec­
t ion provided by the safety belts.
If the front airbags deploy, the knee airbags also
deploy in frontal collisions when the deployment
threshold stored in the control unit is met
¢ page 2 79, More important things to know
about front airbags .
In addition to their normal safety function, safe­
ty belts help keep the driver or front passenger in

occupant safety that nothing should be in their
way when they deploy.
Fully inflated airbags in combination with proper­
ly worn safety belts slow down and limit the oc­
cupant's forward movement and help to reduce
the risk of injury.
Important safety instructions on the knee
airbag system
A ppl ies to: ve hicles with knee a ir b ags
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 .
A WARNING
An inflating knee airbag can cause serious in­
jury . Wearing safety belts incorrectly and im­
proper seating posit ions 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 locations. 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
minimum 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 side, or if the seat is
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 airbag can
inflate without interference. Objects be­
tween you and the airbag can increase the risk of injury in an accident by interfering
-
Airbag system
with the way the airbag deploys or by being
pushed into you as the airbag deploys.
- Never let anybody, especially children or
animals 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 (shopping
bags, for example) can interfere with or
prevent proper deployment of the airbag.
Small objects can be thrown through the
vehicle if the airbag deploys and injure you
or your passengers.
- Make sure there are no cracks, deep scratch­
es or other damage in the area of the instru­
ment panel where the knee airbags are lo­
cated.
- If children are incorrectly seated, their risk
of injury increases in a collision

Airbag System" in compliance w ith United States
Federal Motor Vehicle Safety Standard (FMVSS)
208, as well as Canada Motor Vehicle Safety
Standard (CMVSS) 208 as applicable at the time
your ve hicle was manufactured.
The Advanced Airbag system in your veh icle has
been cert ified to meet the "low-risk" require­
ments for 3- and 6-year old children on the pas­
senger s ide and small adults on the driver side.
The low risk deployment cr iteria are intended to
reduce the risk of injury through interaction with
the airbag that can occur, for examp le, by being
too close to the steering whee l and instrument
panel when the airbag inflates. In addition, the
system has been certified to comply with the
"suppress ion" requ irements of the Safety Stand­
ard, to turn off the front airbag for infants up to
12 months who are restrained on the front pas-
296
senger seat in child restraints t hat are listed in
the Standard.
Even though your vehicle is eq uipped w it h an Ad­
vanced Airbag system, all childr en, especially
those 12 years and younger, shou ld always ride
in the back seat properly restrained for their age
and s ize. The airbag on the passenger side makes
the front seat a potentially dangerous p lace for a
ch ild to ride. The front seat is not the safest place
for a ch ild in a forward -facing ch ild safety seat . It
can be a very dangerous place for an infant or a
larger child in a rearward-facing seat.
The vehicle's Advanced Airbag System has a ca­ pacit ive passenger detection system in the front
passenger seat cushion that can detect the pres­
ence of a baby or a ch ild in a child restraint sys­
tem on this seat.
The capacitive passenger detection system regis­
ters the changes that result in an electrical field
when a child, a chi ld restra int, and a baby b lanket
are on the front passenger seat. The change in
the measured capacitance due to the presence of
a chi ld, a child restraint, and a baby blanket 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
i es depending on the type of system and specific
make and model.
The electrical capacitance of the various types, makes, and models of child restraints specified
by the U.S. National Highway Traffic Safety Ad­
ministration (NHTSA) in the relevant safety
standard are stored in the Advanced Airbag Sys­
tem control unit together with the capacitances
typ ica l of infants and a 1-year old ch ild. When a
child restraint is used on the front passenger
seat with a typical 1 year-old infant, the Ad­
vanced Airbag System compares the capacitance
measured by the capacitive passenger detection
system with the data stored in the e lectronic con­
tro l unit .

-Do not use run-flat tires on your vehicle. Using them when
not permitted can lead to ve­
hicle damage or accidents.
-If you install wheel covers on
the vehicle, make sure they al­ low enough air circulation to
cool the brake system. If they
do not, this could increase the risk of an accident.

Tire wear
Check the tires regular ly for wear.
-Inflation pressure that is too low or high can increase tire wear
considerably.
-Driving quickly through curves,
rapid acceleration and heavy
braking increase tire wear.
l ) Obey any applicable regulations in your
country.
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
c::> fig. 2 76. 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 treadwear
indicators. Replace the tires with
new ones
