2015 AUDI S3 sensor

104 Audi side assist
-If vehicles are approaching or being
left behind very quickly. The display
may not turn on in time.
- In poor weather conditions such as
heavy rain, snow or heavy mist.
- On very wide lanes, in tight curves, or if
there is a rise in the road surface.
Vehicles in the adjacent lane may not
be detected because they are outside
of the sensor range.
- Audi side assist cannot detect all vehicles
under all conditions, which can increase
the risk of accidents.
- Please note that side assist only displays
approaching vehicles or vehicles in your
blind spot if your vehicle is traveling at
least 19 mph (30 km/h).
- In certain situations, the system may not
work or its function may be limited. For
example:
- The display may not turn on at the
right time if vehicles are approaching
or passing very quickly.
- In poor weather conditions, such as
heavy rain, snow or fog.
- In very wide lanes, in tight curves or
when there are slopes in the roadway,
vehicles in the neighboring lanes may not be detected because they are out­
side of the sensor range.
The sensors can be displaced by impacts or damage to the bumper, wheel housing and
underbody. This can affect the system. Have your authorized Audi dealer or au­
thorized service facility check their func­
tion.
{D) Tips
- If the window glass in the driver's door
or front passenger's door has been tint­
ed, the display in the exterior mirror may
be misinterpreted .

& WARNING
-Always look for traffic and check the area
around your vehicle by looking at it di­
rectly as well. The parking system cannot
replace the driver 's attention. The driver
is always responsible when entering or
leaving a parking space and during simi­
lar maneuvers .
- Please note that some surfaces, such as
clothing, are not detected by the system.
- Sensors and cameras have blind spots in
which people and objects cannot be de­
tected . Be especially cautious of small
children and animals .
- Always pay attention to the area around
the vehicle -using the rearview mirror,
too.
- The sensors can be displaced by impacts
or damage to the radiator grille, bumper,
wheel housing and the underbody. The
parking system may become impaired as
a result . Have your authorized Audi deal­
er or authorized service facility check
their function . -
Make sure the sensors are not obstructed
by stickers, deposits or other materials.
If they are, the sensor function could be impaired. For additional information on
cleaning, refer to¢

- Some objects are not detected or dis­
played by the system under certain cir­
cumstances:
- Objects such as barrier chains, trailer
draw bars, vertical poles or fences
- Objects above the sensors such as wall
extensions
- Objects with specific surfaces or struc­
tures such as chain link fences or pow­
der snow
- If you continue driving closer to a low-ly­
ing object, it may disappear from the
sensor range. Note that you will no lon­
ger be warned about this obstacle.
- The sensors can be displaced by impacts
or damage to the radiator grille, bumper,
wheel housing and the underbody. The
parking system may become impaired as
a result. Have your authorized Audi deal­
er or authorized service facility check

152 Airbag sys te m
cause the capacitive passenger detection
system in the seat to s ignal to the A irbag
System that the seat is occupied by a person when it is not, or to signal that it
is occupied by someone who is heavier
than the person actually s itting on the
seat. The presence of additional objects
cou ld cause the passenger front airbag
to be t urned on when it sho uld be off, or
cou ld cause the airbag to work in a way
that is different from the way it wou ld
have worked without the object on the
seat.
- Make sure that the
PA SSENGER AIR BAG
OFF
light comes on and stays on all the
t ime whenever the ignition is switched
on.
Advanced Airbag System components
The front passenger seat in your vehicle has a
lot of very important parts of the Advanced
A irbag System in it . These parts include the
capacitive passenger de tect ion system, wir­
ing, b ra ck ets, and more. The cont ro l unit
monitors the system on the front passenger
seat when the ign ition is switched on and
turns the airbag indicato r light on when a
malfunction in the one of the system compo­
nents is detected¢
page 157 . Because the
fro nt 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 Ad­
vanced A irbag System for the front passenger
se at from doing i ts job in a c rash.
The front Advanced Airbag System
consists of the following:
- Crash sensors in the fro nt of the ve hicle that
m easure ve hicle accelera tion/de celera tion
to provide info rmation to the Advanced Air­
bag System abo ut the seve rity of the crash.
- An electronic cont ro l u nit, with integrated
c rash sensors for front and side impacts.
The cont ro l unit "decides" whether to fire
the front airbags based on the information received from the crash sensors. The contro l unit also "decides" whether the sa
fety belt
pretensioners sho uld be activated.
- An Advanced A irbag w ith gas generato r for
the driver inside the steering wheel h ub.
- An Advance d Airbag w ith g as generato r in­
side the inst rument panel for the front pas ­
senger.
- A capacit ive passenger detection system un­
de rneath the front passenger seat cover .
This system meas ures the electrical capac i­
tance of the person in the seat. The informa ­
tion registered is sent cont inuo usly to the
electronic control un it to regu late deploy­
ment of the front Advanced A irbag on the
passe nger side .
- An airbag monitor ing system and indicator
light in the instrument cluster¢
page 156 .
-A sensor in each front seat registers the dis­
tance betwee n the respective seat and the
steer ing whee l o r inst rument panel. The in­
formation registered is sent cont inuous ly to
t he ele ct ron ic contro l unit to regula te de­
p loyment of the front Adva nced A irb ags .
- The
PASSENGER AIR BAG OFF light comes
on and stays on in the center of t he instr u­
ment p anel ¢
page 217 and t ells yo u when
the fron t Advanced Airbag on the passenge r
side has been turned off.
- A sensor in the safety be lt latch for the driv ­
er and for the front seat passenger that
senses whether t hat safety belt is latched or
not and transmits this information to the
electronic control un it.
A WARNING
Damage to the front passenger seat can
prevent the front airbag from wor king
p roperly.
- Improper repair or d isassembly of the
front passenge r and dr iver sea t will pre­
vent the Advanced Airbag System from
functioning p roperly.
- Repairs to the front passenge r seat must
be pe rformed by qualified and p roperly
trained workshop personnel.
- Never remov e the front passenger o r
d river seat from the vehicle.
-

156 Airbag sys te m
the front airbag during braking or in a
sudden maneuver. Objects near the air­
bags can become project iles and cause
injury, part icularly when the seat is re­
cl ined.
- Never place or transport objects on the
front passenger seat . Objects on the
front passenger seat could cause the ca­ pacitive sensor in the seat to s ignal to
airbag system that t he seat is occupied
by a person when it in fa ct is not, o r that
the person on the seat is heavie r than he
or she actually is. The change in electric
capacitance because of such objects can
cause the passenger front a irbag to be
turned on when it sho uld be off, or can
cause the airbag to work in a way that is
different from the way it wou ld have
worked w ithout ob jects on the seat.
- Always make sure that there is nothing
on the front passenge r seat that will
cause the capacitive passenge r detection
sys tem in the seat to s ignal to t he A irbag
System th at the se at i s oc cupied by a
person when i t is not, or to signa l that it
is occupied by someone who is heavier
than the person actually sitting on t he
seat. The presence of an object co uld
cause the passenger front a irbag to be
turned on when it sho uld be off, or could
cause the airbag to work in a way that is
differe nt from the way it wou ld have
wor ked w ithout the object on the seat.

The Advanced Airbag System as well as the
s ide airbags and side curta in a irbags w ith
eject ion mit igat ion features (including the
electron ic contro l unit, se nsors a nd system
wiring) are all mon itored continuously to
make su re that they are functioning p roperly

www.dtsc.ca.gov/hazardouswaste/per­chlorate. When the vehicle or parts of the
restraint system includ ing airbag modules
and safety belts with pretensioners are
scrapped, all applicable laws and regula­
tions must be observed. Your authorized
Audi dealer is familiar with these require­
ments and we recommend that you have
your dealer perform this serv ice for you.
Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag Sys­
tem performs in a crash. For example, using
tire-r im combinations not approved by Audi,
lowering the vehicle, changing the stiffness of
the suspension, including the springs, suspen­
sion struts, shock absorbers etc. can change
the forces that are measured by the airbag sensors and sent to the electron ic control
unit. Some suspension changes can, for exam­
ple, increase the force levels measured 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 meas­
ured by the sensors and prevent the airbag
from deploying when it should .
A WARNING
Changing the vehicle's suspension includ­
ing use of unapproved tire-rim combina­
tions can change Advanced Airbag per­
formance and increase the risk of serious
personal injury in a crash.
- Never install suspension components
that do not have the same performance characteristics as the components origi­
nally insta lled on your vehicle.
- Never use tire-rim combinations that
have not been approved by Audi.
Airbag system 161
Knee airbags
Description of knee airbags
Applies to vehicles: wi th knee airbags
The knee airbag system can provide supple­
mental protection to properly restrained
front seat occupants.
Fig. 133 Driver's kn ee airbag
The dr iver knee airbag is in the instrument
panel underneath the steering wheel
¢
fig. 133, the airbag for the passenger is at
about the same height in the instrument pan­
el underneath the glove compartment.
The knee airbag offers additional protection
to the driver's and passenger's knees and up ­
per and lower thigh areas and supplements
the protection provided by the safety belts.
If the front airbags deploy, the knee airbags
also dep loy in frontal collisions when the de­
ployment threshold stored in the control unit
is met¢
page 154, More important things to
know about front airbags.
In addition to their normal safety function,
safety belts help keep the driver or front pas­
senger in position in a frontal collision so that
the airbags can provide supplemental protec­
tion.
The airbag system is not a substitute for your
safety belt. Rather, it is part of the overall oc­
cupant restraint system in your vehicle. Al­
ways remember that the airbag system can
only help to protect you if you are wearing
your safety be lt and wearing it properly. This
is why you should always wear your safety
belt, not just because the law requires you to
do so¢
