wheel AUDI S3 SEDAN 2017 Repair Manual

Airbag system
-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 .
- Never hold the steering wheel at the 12
o'clock position or with your hands any­
where inside the steering wheel or on the steering wheel hub. Holding the steering
wheel the wrong way increases the risk of
severe injury to the arms, hands, and head if
the driver airbag deploys.
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 .
272
-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
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
facing child safety 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
..,.

CXl CXl .... N ,.__

(CMVSS) 208 as ap plic able at the time your vehi­
cle was manufactured.
The front Advanced Airbag System supp lements
the safety belts to prov ide additional pro te ction
for the driver's and front passenger 's heads and
upper bodies in frontal crashes . The airbags in­
flate only in fronta l impacts when the veh icle de­
celerat ion is high enough.
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 only 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 properly re­
stra ined, not jus t because the law requ ires yo u to
be.
The Advanced Airbag System in your ve hicle has
been ce rtified to meet the
"low r isk" requi re­
men ts for 3 and 6 yea r-o ld children o n the pas­
senger side and very sma ll adul ts on the drive r
side . The low r isk dep loymen t cr iteria are inten d­
ed to help reduce the risk of injury through inter­
action with the front airbag that can occur, for
examp le, by being too close to the steering wheel
and instrument pane l when the airbag inflates .
I n addition, the system has been certified to
comp ly with the "supp ression" requirements of
the Safety Standard, to turn off the front a irbag
for infants 12 months old and younger who are
restrained on the front passenger seat in child re­
stra ints that are listed in the Standard
c::> page 295, 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 restrained
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 Ai rbag System in your
vehicle was ce rt ified. For a listi ng of the ch ild
restra ints tha t were used to certify your veh i­
cl e's compl iance wi th the US Safe ty St andard

Airb ag sys tem
-When a pe rson is detected on the front passen ­
ger seat that has an elect rical capacitance that
is more than the total e lectr ica l capacitance of
a child that is about
1 year o ld restrained in one
of the rear-fac ing or forward-facing infant re­
straints (listed in Federa l Motor Vehicle Safety
Standard 208 with which the Advanced Airbag
System in you r vehicle was cert ified), t he front
ai rbag on the passenger side may or may no t
dep loy.
T he
PASSENGER AIR BAG OFF lig ht comes o n
whe n the elect ronic control unit detects a tota l
elect rical capacitance on the front passe nger sea t
t h at re quires the front airbag to be turned off. If
t h e
PASSENGER AIR BAG OFF ligh t 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 an impact
that meets the cond itions stored in its memory.
If the total e lectr ica l capacitance registered on
the front passenger seat is more than that of a
typ ica l 1 year -old, b ut less than the weight of a
small adult, the front a irbag on the passenger
s ide may deploy (the
PASSENGER AIR BAG OF F
light does not come on) .
For e xample , the airbag may deploy if :
-a small ch ild that is heav ier than a typ ica l 1
yea r-old child is on the front passenger seat
(regard less of whether the child is in one of the
child safety seats listed
c::> page 295),
- a child who has outgrown c hild restraints is on
the front passenger seat .
If the front passenge r a irbag 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 a ir bag deploys, the Feder ­
al S tanda rd requi res t he ai rbag to meet the " low
risk" deployment criteria to he lp red uce the r isk
of i njury 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 ¢

switched on and turns the airbag indicator light
on when a malfunction in the one of the system
components is detected
c::> page 279. Because
the front passenger seat contains important
parts of the Advanced Airbag System, you must
take care to prevent it from being damaged .
Damage to the seat may prevent the Advanced
Airbag System for the front passenger seat from
doing its job in a crash.
The front Advanced Airbag System consists
of the following:
-Crash sensors in the front of the vehicle that
measure vehicle acceleration/ deceleration to
provide information to the Advanced Airbag
System about the severity of the crash.
-An electronic control unit, with integrated
crash sensors for front and side impacts. The
control unit "decides" whether to fire the front
airbags based on the information received from
the crash sensors. The control unit also
"de­
cides" whether the safety belt pretensioners
should be activated .
-An Advanced Airbag with gas generator for the
driver inside the steering wheel hub.
-An Advanced Airbag with gas generator inside
the instrument panel for the front passenger.
-A capacitive passenger detection system under­ neath the front passenger seat cover. This sys­
tem measures the electrical capacitance of the person in the seat. The information registered
is sent continuously to the electronic control
unit to regulate deployment of the front Ad­
vanced Airbag on the passenger side .
-An airbag monitoring system and indicator
light in the instrument cluster
c::> page 2 79.
-A sensor in each front seat registers the dis­
tance between the respective seat and the
steering wheel or instrument panel. The infor­
mation registered is sent continuously to the
electronic control unit to regulate deployment
of the front Adv a need Airbags.
-The PASSENGER AIR BAG OFF light comes on
and stays on in the center of the instrument
panel
c::> page 316 and tells you when the front
Advanced Airbag on the passenger side has been turned off.
Airbag system
-A sensor in the safety belt latch for the driver
and for the front seat passenger that senses
whether that safety belt is latched or not and
transmits this information to the electronic control unit.
A WARNING ,.__
Damage to the front passenger seat can pre­
vent the front airbag from working properly.
-Improper repair or disassembly of the front passenger and driver seat will prevent the
Advanced Airbag System from functioning properly.
-Repairs to the front passenger seat must be
performed by qualified and properly trained
workshop personnel.
-Never remove the front passenger or driver
seat from the vehicle.
-Never remove the upholstery from the front
passenger seat.
-Never disassemble or remove parts from the
seat or disconnect wires from it.
- Never carry sharp objects in your pockets or
put them on the seat. The capacitive 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 can influence the capacitance regis­
tered by the capacitive passenger detection
system, so that incorrect information is pro­
vided to the airbag control unit.
-Never store items under the front passenger
seat. Parts of the Advanced Airbag System
under the passenger seat could be dam­
aged, preventing them and the airbag sys­
tem from working properly.
-Never place 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 Air­
bag System from recognizing child re­
straints or occupants on the front passenger
seat and prevent the side airbag in the seat
backrest from deploying properly.

Airbag system
A WARNING
A child in a rearward-facing child safety seat
installed on the front passenger seat will be
seriously injured and can be killed if the front
airbag inflates - even with an Advanced Airbag
System.
- The inflating airbag will hit the child safety
seat or infant carrier with great force and
will smash the child safety seat and child against the backrest, center armrest, door
or roof.
-Always install rear-facing child safety seats on the rear seat.
- If you must install a rearward facing child
safety seat on the front passenger seat be­ cause of exceptional circumstances and the
PASSENGER AIR BAG OFF light does not
come on and stay on, immediately install
the rear -facing child safety 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
278
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
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 .
A 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.

whenever the ignition is switched on.
,& WARNING
- If the PA SSENGER AIR BAG OFF light does
not go out when an ad ult is sitting on the
front passenger seat after taking the steps
described above, make sure the adu lt is
properly seated and restrained at one of the
rear seat ing positions.
- Have the airbag system inspected by your
Audi dealer before transporting anyone on
the front passenger seat.
(D Tips
If the capacitive passenger detection system
determines that the front passenger seat is
empty, the fronta l airbag on the passenger
side will be turned off, and the
P ASSE NGER
A IR BAG OFF light will stay on.
Repair , care and disposal of the airbags
Parts of the airbag system are installed at many
d ifferent places on your Aud i. Install ing, remov­
ing, servic ing or repa iring a part in an area of the
veh icle can damage a pa rt 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 make sure that the effectiveness of the
system w ill not be impaired and that discarded
components do not cause injury or pollute the
environment .
,& WARNING
Improper care, servicing and repair proce­
dures can increase the r isk of personal injury
and death by preventing an airbag from de­
ploying when needed or deploying an airbag
unexpectedly:
282
- Never cover, obstruct, or change the steer­
ing wheel horn pad or airbag cover or the in­
strument panel or modify them in any way.
- Never attach any objects such as cup holders
or telephone mountings to the surfaces cov­
ering the a irbag un its.
- For cleaning the horn pad or instrument
panel, use only a soft, dry cloth or one mois­
tened w ith plain water. Solvents or cleaners
could damage the airbag cover or change
the st iffness or strength of the material so
that the airbag cannot deploy and protect properly.
- Never repair, adjust, or change any parts of
the airbag system.
- All work on the steering wheel, inst rument
panel, front seats or e lectr ica l system ( in­
cluding the instal lation of a udio eq uipment,
cellular telephones and CB radios, etc.)
m ust be performed by a qualified technician
who has the training and specia l equipment
necessary.
- For any work on the airbag system, we strong ly recommend that you see your au­
thorized Audi dealer or qualified workshop.
- Never modify the front bumper or parts of
the vehicle body.
-Always make sure that the side airbag can inflate without interference:
- Never install seat covers or replacement upholstery over the front seatbacks that
have not been specif ica lly approved by
A udi.
- Never use additional seat c ushions that
cover the areas where the side airbags in­
flate.
- Damage to the orig inal seat cove rs or to
the seam in the area of the s ide airbag
module mus t always be repai red immedi ­
ate ly by an authorized Audi dealer.
- The a irbag sys tem can deploy on ly once. Af­
ter an airbag has been deployed, it m ust be
replaced with new replacement parts de ­
signed and approved especia lly for your
Audi model version . Replacement of com­
plete airbag systems or airbag components
must be performed by qua lified workshops
only . Make sure that any airbag service

the risk of injury.
Important safety instructions on the knee
airbag system
A ppl ies to: ve hicles 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 .
A WARNING
An inflating knee airbag can cause ser ious in­
jury. Wearing safety belts incorrectly and im­
proper seating posit ions increase the r isk of
ser ious personal inj ury and death whenever a
vehicle is being used .
- The knee airbag system cannot protect you
prope rly if you are seated too close to any of
the a irbag lo cat ions. When ad justing thei r
seat positions, it is important that both the
dr iver 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 steer ing wheel/ins trument
panel.
- at least 4 inches (10 cm) between the
knees a nd the lower pa rt of the instru­
ment panel.
- T he risk of persona l injury inc reases if you
lean forward or to the s ide, or if the sea t is
imp roperly posi tioned and you are not wear­
ing your safety belt . The risk increases even
more should the airbag deploy .
- Always make sure tha t the knee airbag can
inflate without interference. Objects be­
tween you and the airbag can increase the risk of inj ury in an accident by inter fer ing
-
Airb ag sys tem
with the way the airbag deploys or by being
pushed into yo u as the a irbag deploys.
- Neve r let anybody, especia lly children or
anima ls r ide in the footwell in front of the
passenger seat. If the airbag deploys, this
can result in serious or fatal i njuries.
- Neve r carry objects of any kind in the foot­
well a rea in front of the driver's or pas­
senger 's seat . Bulky objects (shopp ing
bags, for example) can i nterfere with or
prevent proper dep loyment 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 c hild ren are incorrectly seated, their risk
of injury increases in

(D Tips
Always replace child restraints that were in­
stalled in a vehicle during a crash. Damage to
a child restraint that is not visible could cause
it to fail in another collision situation.
Advanced front airbag system and children
Your vehicle is equipped with a front "Advanced
Airbag 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 vehicle 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
"suppression" requirements of the Safety Stand­
ard, to turn off the front airbag for infants up to 12 months who are restrained on the front pas-
294
senger seat in child restraints that are listed in
the Standard.
Even 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 restrained for their age
and size. The airbag on the passenger side makes
the front seat a potentially dangerous place for a child to ride. 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
larger child in a rearward-facing seat.
The vehicle's Advanced Airbag System has a ca­ pacitive passenger detection system in the front
passenger seat cushion that can detect the pres­
ence of a baby or a child 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 child restraint , and a baby blanket
are on the front passenger seat. The change in
the measured capacitance due to the presence of
a child, 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
ies 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
typical of infants and a 1-year old child. 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 electronic con­
trol unit .

General information
~check your tires regularly for
damage (punctures, cuts, cracks
and bulges). Remove foreign ob­
jects from the tire tread.
~ If driving over curbs or similar
obstacles, drive slowly and ap ­
proach the curb at an angle.
~ Have faulty tires or rims re­
placed immediately.
~ Protect your tires from oil,
grease and fuel.
~ Mark tires before removing
them so that the same running direction can be maintained if
they are reinstalled .
~ Lay tires flat when storing and
store them in a cool, dry location
with as little exposure to light as possible.
(i}) Note
-Please note that summer and
winter tires are designed for
the conditions that are typical i n those seasons. Audi recom­
mends using winter tires dur­
i ng the winter months. Low
temperatures significantly de­ crease the elasticity of summ­
er tires, which affects traction
328
and braking ability. If summer
tires are used in very cold
temperatures, cracks can form on the tread bars, resulting in
permanent tire damage that
can cause loud driving noise
and unbalanced tires.
-Burnished, polished or chromed rims must not be used in winter driving condi­
tions. The surface of the r ims
does not have sufficient corro­
sion protection for th is and
could be permanently dam­
aged by road salt or similar
substances.
