Acoustic parking
system
Rear acoustic park assist
Applies to vehicles: with 4-cha nnel acoustic park assist
Acoustic park assist gives a warning about
obstacles behind the vehicle.
Desc ription
The rear acoust ic park assist (4-channe l
acoust ic pa rk assist) dete rm ines the d istance
of the vehicle from an obstacle us ing u ltra­
sonic sensors . The sensors are in the rear
bumper . The vol ume and the pitch of the
chimes can be adjusted through the menu dis­ p lay
c::> page 27.
The range at which the sensors start to meas­
ure is
about :
To the side
Center rear
Activation
2 feet (0.60 m)
S feet (1.60 m)
The parking assist is ac tivated when re ver se
gear
i s engaged. A brief tone confirms tha t
the system is activated.
Backing up
Distance warning when backing up starts
when an obstacle is detected in the range of
the park assist sys tem. As t he d istance de­
creases, t he time interva l be tween the audib le
tones becomes sho rter.
When the d istance is less than 1 foot (0 .30
m), the tone becomes cont inuous . At t his
po int yo u should stop b acking up.
P lease note that low objects already signalled
by a wa rning can disappear from the system 's
detection range and w ill not continue to be
signa lled.
On th e ro ad 93
Potent ial malfunct ions
If a warning bu zzer so unds fo r a few seconds
when the ignition is switched o n, there is a
system malfunction with the acoustic park as ­
sist. If the ma lfunction persists unti l the igni­
tion is switched off, there will be no aco ustic
warning at the next attempt to act ivate the
system. Have the prob lem corrected.
There is no conf irmation tone when reve rse
gear is engaged if there is a system malfunc­
tion.
For t he parking assist to ope rate, the sensors
must be kept clean and free of ice.
A WARNING
- Sensors have blind spots in wh ich objects
cannot be detected. Pay spec ia l attent ion
to small children and a nimals . They can­
not a lways be detected by the sensors -
danger of an accident!
- The parking assist ca nnot replace the
driver's atte ntion. The driver alone is re­
sponsib le for pa rking and simi lar d riving
maneuve rs. Always wat ch whe re you are
d riving.
(D Note
L ow obstacles already signa lled by a warn­
i ng can d isapp ear from the system's detec­
tion range as they a re approached and w il l
not cont inue to be s ignalled. Objects such
as barrier chains, trailer d raw bars, th in

Advanced Airbag System components
The front passenger seat in your vehicle has a
l ot of very important parts of the Advanced
Airbag System in it. These parts include the
weight-sens ing ma t, sensors, wiring, brack­
ets, and mo re. The function of the system in
the front passenger seat is checked by the
e lectronic control unit when the ignition is on .
The control unit monitors the Advanced Air­ bag System and turns the airbag indicator
light on when a malfunction in the system
components is detected. The function of the
airbag ind icator light is described in greater
deta il below. Because the front passenger
seat contains impo rtant parts of the Ad­
vanced A irbag System, you m ust take care to
p revent it from being damaged. Damage to
the seat may prevent the Advanced Airbag for
the front passenger seat from doing its job in
a crash .
The front Advanc ed Airbag Syst em
con sis ts o f th e following :
-Crash sensors in the front of the vehicle that
measure vehicle acceleration/deceleration
to provide information to the Advanced Air­ bag System about the severity of the crash.
-An electronic control unit, with integrated
crash sensors for front and side impacts .
The cont ro l unit "decides" whether to fire
the front airbags based on the information r eceived from the c rash sensors. The control
unit a lso "dec ides" whet her the safety be lt
pretensione rs should be activated.
- An Advanced Airbag with gas generator for
the d river ins ide the steer ing whee l hub.
- An Advanced Airbag with gas generator in­
s ide t he instr ument pane l for the front pas­
senger.
A irbag system 129
- A weight-sensing mat under the upho lstery
padding of the front passenger seat cushion
that measures the total weight on the seat .
The informat ion reg istered is sent continu­
ously to the electron ic control unit to regu­
late deployment of the front Advanced Air­
bag on the passenger side.
- An airbag monitoring system and ind icator
light in the instrument cluster
¢page 133.
-The PASSENGER AIR BAG OFF light comes
on and stays on in the center of the instru­
ment panel
c:::> page 133, fig . 134 and tells
you when the front Advanced Airbag on the passe nger side has been tu rned off.
- A senso r below the safety belt latch fo r the
front seat passenger to measure the tension
on the safety be lt. T he ten sion on the safety
be lt and the weight regis tered by the
weight -sensing mat he lp the control unit
"decide" whether the front airbag fo r the
front passenger seat should be turned off or not
¢ page 123, Child restraints on the
front seat -some important things to
know.
-A sensor in the safety belt latch for the driv­
er and for the front seat passenger that
senses whether that safety belt is latched or
not and transmits this information to the
electronic contro l un it .
A WARNING
D amage to the front passenger seat can
p revent the front airbag from wor king
properly.
- Imp roper repai r or d isassembly of the
fr on t passenge r and dr iver seat will pre­
vent the Advanced Airbag System from
functioning p roperly.
- Repairs to the front passenger seat must
be pe rformed by qualified and p roperly
trained workshop personne l.
- Never remove the front passenger or driver seat from the vehicle .
- Never remove the upho lstery from the
front passenger seat .
- Never disassemble or remove p arts from
-
the sea t or disconnect wires from it. ..,.

130 Airbag system
-Never carry sharp objects in your pockets
or place them on the seat. If the weight­
sensing mat in the passenger seat is
punctured it cannot work properly .
- Never carry things on your lap or carry
objects on the passenger seat. Such items can increase the weight registered
by the weight-sensing mat and send the
wrong information to the airbag control
unit.
- Never store items under the front pas­
senger seat. Parts of the Advanced Air­
bag System under the passenger seat
could be damaged, preventing them and
the airbag system from working proper­
ly.
- Never place seat covers or replacement
upholstery that have not been specifical­
ly approved by Audi on the front seats.
- Seat covers can prevent the Advanced Airbag System from recognizing child re­
straints or occupants on the front pas­
senger seat and prevent the side airbag
in the seat backrest from deploying prop­
erly .
- Never use cushions, pillows, blankets or
similar items on the front passenger
seat. The additional padding will prevent
the weight-sensing mat in the seat from
accurately registering the child restraint
or person on the seat and prevent the
Advanced Airbag System from function­
ing properly.
- If you must use a child restraint on the
front passenger seat and the child re­
straint manufacturer's instructions re­
quire the use of a towel, foam cushion or
something else to properly position the
child restraint, make certain that the
PASSENGER AIR BAG OFF light comes
on and stays on whenever the child re­
straint is installed on the front passen­ ger seat .
- If the
PASSENGER AIR BAG OFF light
does not come on and stay on, immedi­
ately install child restraint in a rear seat­
ing position and have the airbag system
inspected by your authorized Audi dealer.
How the Advanced Airbag System
components work together
The front Advanced Airbag System and the
side airbags supplement the protection of­
fered by the front three-point safety belts
with pretensioners and load limiters and the
adjustable head restraints to help reduce the
risk of injury in a wide range of accident and
crash situations. Be sure to read the impor­
tant information about safety and heed the
WARNINGS in this chapter.
Deployment of the Adva need Airbag System
and the activation of the safety belt preten­
sioners depend on the deceleration measured
by the crash sensors and registered by the
electronic control unit. Crash severity depends
on speed and deceleration as well as the mass
and stiffness of the vehicle or object involved
in the crash.
When the electronic control unit registers a
low severity crash and the safety belt is being
used , the airbag will not deploy. If the safety
belt is not being used, the first stage deploys,
followed by the second stage after a much lat­
er time in the crash sequence.
If the electronic control unit registers a crash
of medium severity, the first stage of the air­
bag deploys followed by the second stage at a
much later time in the crash sequence - re­
gardless of whether the safety belt is being
used or not . In higher severity crashes as reg ­
istered by the electronic control unit, both the
first and second stages deploy almost at the same time.
On the passenger side, regardless of safety
belt use, the airbag will be turned off if the
weight on the passenger seat is less than the
amount programmed in the electronic control
unit. The front airbag on the passenger side
will also be turned off if one of the child safe­
ty seats that has been certified under Federal
Motor Vehicle Safety Standard 208 has been
recognized on the seat. The
PASSENGER AIR
BAG OFF
light comes on and stays on to tell
you when the front Advanced Airbag on the passenger side has been turned off ..,_

Monitoring the
Advanced Airbag
System
I Airbag monitoring indicator light
Two separate indicators monitor the function
of the Advanced Airbag System: the airbag
monitoring indicator light and the
PAS SEN ­
GER AIR BAG OFF
light.
The Advanced Airbag System (including the
e lectronic control unit, sensor circuits and sys­
tem wiring) is monitored continuously to
make sure that it is functioning properly
whenever the ignit ion is on . Each t ime you
turn on the ignition, the airbag monitor ing in­
d icator light
I will come on for a few seconds
(self diagnostics) .
t!i The syste m mus t be insp ected when the
indicato r light:
- does not come on when the ignit ion is
switched on,
- does not go out a few seconds after yo u
have switched on the ignition, o r
- comes on while d riving .
If an airbag system malfunction is detected,
the
I indicator light will first start flashing to
catch the driver's attention and then stay on
continuously to serve as a constant reminder
to have the system inspected immediately.
If a malfunction occurs that turns the front
a irbag on the passenger side off, the
PASSEN­
GER AIR BA G OFF
light will come on and stay
on whenever the ignition is on.
_& WARNING
An airbag system that is not funct ioning
properly cannot provide supp lemen tal p ro­
tection in a frontal crash.
- If the airbag indicator l igh t comes on, it
means that there may be something
wrong wit h the Advanced Airbag System.
It is possible that the airbag will inflate
when it is not s upposed to, or wi ll not in­
flate when it should.

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, us ing
tire-r im combinations not approved by Aud i,
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 a irbag
se nsors and sent to the electron ic control
u ni t. Some suspens ion changes c an, for exam­
p le, increase the force levels measured by the
sensors and make the airbag system deploy in
crashes in w hic h it would not dep loy if the
changes had not been made. Other k inds of
changes may reduce the force levels meas­
ured by the sensors and prevent the airbag
from deploying when it shou ld .
The sensors in the safety belt buckle for the
driver and front passenger seat tell the elec­
tronic control module if the safety belt is
l atched or not. If the safety belt is being used,
the front airbag will deploy at a slightly high­
e r rate of vehicl e deceleration than if the safe­
ty belt is not being used. Therefore, in a par­
ticular co llision, it is poss ible th at an a irbag
will not deploy at a seating position where the
safety be lt is bei ng used but will inflate at the
position whe re the safety belt is not being
used. It is important that nothing interfere
with the safety belt buckles so t hat the sen­
sors can send the correct information about
safety belt use to the electron ic cont rol unit.
A WARNING
Cha nging the vehicle's s uspension inclu d­
ing use of u napproved t ire-rim comb ina­

Side airbags
Description of side airbags
The airbag system can provide supplemental
protection to properly restrained occupants.
Fi g. 135 Side a irbag location in t he drive r's seat
The side airbags are located in the sides of the
front seat backrests~
fig. 135 and the rear
back rest* facing the doors . Th ey are id entified
by the wo rd "AIRBAG".
The side airbag sy stem basically consi st s of :
-the electron ic control modu le and external
side impact sensors
- the two side airbags located in the s ides of
the front backrests
- two rear side airbags (as an ordered
option)
- t he airbag warn ing light in the ins trument
cl uste r.
T he airbag system is mo nitored e lec tronically
t o m ake ce rtain tha t it is fu nction ing p ro perl y
at all times . Each time you turn on the ig ni­
tion, the airbag system indicator light will
come on for a few seconds (self diagnostics) . ..,.

138 Airbag sys te m
The side airbag system supplements the safe­
ty belts and can help to reduce the risk of in­
jury to the driver's, front and rear* passeng­
er's upper torso and head on the side of the
vehicle that is struck in a side collision. The
a irbag dep loys only in side impacts and only
when the vehicle acceleration registered by
the contro l unit is high enough. If th is rate is
below the refe rence value p rogrammed into
the contro l unit, the side airbags will not be
tr iggered, even though the car may be badly
damaged as a result of the collision.
It is not
possible to define an airbag triggering range
that will cover every possible angle of impact,
since the c ircumstances will vary considerab ly
between one collision and another. Important
factors include, fo r example, the nature (hard
or soft) of the impacting object, the angle of
impact, veh icle speed, etc.
q page 139, Im­
portant safety instructions on the side airbag
system.
As ide from the ir normal safety function, safe­
ty belts work to he lp keep the driver or front
passenger in position in the event of a side
coll is ion so that the side a irbags can provide
p rotection.
The airbag system is
not a substitute for your
safety belt. Rathe r, it is pa rt of the overall oc­
cupant res traint system in your ve hicle. Al­
ways remember that the side airbag system
can only help to protect you if you are wearing
your safety be lt and wearing it properly. This
is another reason why you sho uld always wear
your safety belts, not just because the law re­
qu ires you to do so
<=')page 113, General
notes.
It is important to remember that while the
supp lemental s ide a irbag system is designed
to reduce the like lihood of serious injur ies,
other i njuries, for example, swell ing, bruising,
and minor abras ions can also be associated
with deployed side a irbags. Remember too,
side a irbags wi ll deploy on ly once and on ly in
cer tain k inds of ac cidents -yo ur sa fety belts
are a lways there to offer protection .
Vehicle damage, repa ir costs or even the lack
of vehicle damage a re not necessar ily an ind i- cation o
f over -sensitive or failed airbag activa­
tion . In
some collisions, both front and side
airbags may inflate . Remember too, that air ­
bags will deploy only once and only in certain
k inds of collisions -your safety belts are al­
ways there to offer protection in those acc i­
dents in which a irbags are not supposed to
deploy or when they have a lready deployed .
The side airbag system will not deploy:
-when the ignit ion is turned off
- in side co llisions when the acceleration
measured by the sensor is too low
- in front -end collisions

140 Airbag system
-Objects between you and the airbag can
increase the risk of injury in an accident
by interfering with the way the airbag
unfolds or by being pushed into you as
the airbag inflates .
- Never place or attach accessories or
other objects (such as cup holders, tel ­
ephone brackets, or even large, bulky
objects) on the doors, over or near the
area marked "AIRBAG" on the seat backrests.
- Such objects and accessories can be­
come dangerous projectiles and cause
injury when the supplemental side air­
bag deploys.
- Never carry any objects or pets in the
deployment space between them and
the airbags or allow children or other
passengers to travel in this position .
- Always use the built-in coat hooks only
for lightweight clothing . Never leave any
heavy or sharp-edged objects in the
pockets that may interfere with side air­
bag dep loyment and can cause personal
injury in an accident .
- Always prevent the side airbags from be­
ing damaged by heavy objects knocking
against or hitting the sides of the seat ­
backs.
- The airbag system can only be triggered
once. If the airbag has been triggered,
the system must be replaced by an au­
thorized Audi dealership.
- Damage (cracks, deep scratches etc .) to
the original seat covers or to the seam in
the area of the side airbag module must always be repaired immediately by an au­
thorized Audi dealer .
- If children are seated improperly, their
risk of injury increases in the case of an
accident
q page 143, Child Safety .
- Never attempt to modify any compo­
nents of the airbag system in any way .
- In a side collision, side airbags will not
function properly if sensors cannot cor­
rectly measure increasing air pressure in­
side the doors when air escapes through larger, unclosed openings in the door
panel.
- Never drive with interior door trim pan­
els removed.
- Never drive when parts have been re­
moved from the inside door panel and
the openings they leave have not been
properly closed.
- Never drive when loudspeakers in the
doors have been removed unless the
speaker holes have been properly
closed.
- Always make certain that openings are
covered or filled if additiona l speakers
or other equipment is installed in the inside door panels.
- Always have work on the doors done by
an authorized Audi dea ler or qualified
workshop.
