The rollbars, reinforced windshield frame and
belt tensioners help protect vehicle occupants
in the event of a rollover.
The rollover protection system functions
when the convertible top is both open and
closed.

A WARNING
Do not use the area behind the headrests
¢ fig. 106 as a storage area . This is the
area where the rollbars deploy .
If the roll­
over protection system is triggered, ob­
jects placed there can be prope lled
through the vehicle and make it more diffi­
cult for the rollbars to dep loy. This inc reas­
es the risk for serious or life -threatening
i njuries.
When is rollover protection deployed?
Rollover protection deploys in a collision or
rollover .
Depending on the colli sion, sensors through­
out the vehicle a nd the contro l module trigge r
the rollover system to deploy.
For safety reasons, rollover protection also de­
ploys during front, side a nd rear co llisions
above a certa in level of sever ity.

Ill-

when an airbag deploys and strikes an occu­pant who is not in the correct seating posi­
tion. A driver is responsible for the safety of
all vehicle occupants and especially for chil­
dren. Therefore:
~ Never permit anyone to assume an incorrect
s itting position in the vehicle while traveling
c:>& .
A WARNING
Improperly worn safety belts increase the
risk of serious personal injury and death
whenever a vehicle is being used .
- Always make sure that all vehicle occu­
pants are correctly restrained and stay in
a correct seating position whenever the
vehicle is being used.
- Always read and heed all WARNINGS and
other important information
c:> page 102.
Safety belt preten­
sioners
How safety belt pretensioners work
In front, side and rear end collisions and in a
rollover above a particular severity , safety
belts in use are tensioned automatically.
The safety belts for the front seating positions are equipped with safety belt pretensioners.
T he system is activated by sensors in front,
side and rear-end collisions and in a rollover of
great severity. This tightens the belt and takes
up belt slack
c:> &. in Service and disposal of
safety belt pretensioner on page 107.
Taking
up the slack helps to reduce forward occupant
movement during a collision .
@ Tips
The safety belt pretensioner can only be
activated once .
- In minor frontal and side collisions, in
rear-end collisions and in accidents in­
volving very little impact force, the safe­
ty belt pretensioners are not activated.
Safety belts 107
-When the safety belt pretensioner is ac­
tivated, a fine dust is released. This is
normal and is not caused by a fire in the
vehicle.
- The relevant safety requirements must
be observed when the vehicle or compo­
nents of the system are scrapped. An au­
thorized Audi dealer is familiar with
these regulations and will be pleased to
pass on the information to you .
- Be sure to observe all safety, environ­
mental and other regulations if the vehi­
cle or individual parts of the system, par­
ticularly the safety belt or airbag, are to
be disposed. We recommend you have
your authorized Audi dealer perform this
service for you.
Service and disposal of safety belt
pretensioner
The safety belt pretensioners are parts of the
safety belts on your Audi . Installing, remov ­
ing, servicing or repairing of belt pretension­
ers can damage the safety belt system and
prevent it from working correctly in a colli­
s ion.
There are some important things you have to
know to make sure that the effectiveness of
the system will not be impaired and that dis­
carded components do not cause injury or pol­
lute the environment .
A WARNING r----
Improper care, servicing and repair proce-
dures can increase the risk of personal in­
jury and death by preventing a safety belt pretensioner from activating when needed
or activating it unexpectedly :
- The belt pretensioner system can be acti­
vated only once. If belt pretensioners have been activated, the system must be
replaced.
- Never repair, adjust, or change any parts
of the safety belt system.

116 Airbag sys te m
- Always move the passenger seat into its
rearmost position in the seat's fore and
aft adjustment range, as far away from
the a irbag as poss ible, before insta lling
the forward-facing child restraint. The backrest must be adjusted to an upr ight
posit ion.
- Make sure that the

light comes on and stays on all the
t ime w henever the ignition is switched
on.
Advanced Airbag System components
The fron t passenger sea t in your vehicle h as a
lot of very important par ts of the Advanced
Airbag System in it. These parts include t he
weight -sensing mat, sensors, wiring, brack­
ets, and more. The function of the system in
the front passenger seat is checked by the
e lectronic control un it when the ignit ion is on.
The control unit mon itors the Advanced Air­
bag System and turns the airbag indicator
l ight on when a ma lfunction in t he system
components is detected. The func tion of the
a ir bag ind icator light is described in greater
detai l be low . Because the front passenger
seat contains important parts of the Ad­
vanced A irbag System, you m ust take care to
prevent it from be ing damaged. Damage to
the seat may prevent the Advanced Airbag for
the front passenger seat from doing its job in
a crash .
The front Advanced Airb ag Sy stem
consists of the following:
- Crash sensors in the front of the veh icle that
measure veh icle acceleration/deceleration
to provide information to the Advanced Air­
bag System abou t the seve rity of the crash.
- An electron ic co ntrol unit, with integ rated
crash sensors for front and side impacts .
T he cont ro l unit "dec ides " w het her to fire
the front airbags based on the information
received from the crash senso rs . The contro l
unit a lso "decides" whethe r the safety be lt
pretensioners should be activated . -
An Advanced A irbag w ith gas generator for
the driver inside the steering w heel hub.
- An Advanced A irbag w ith gas generato r in­
side the inst rument panel for the front pas­
senger.
- A we ight -sensing mat unde r th e upho ls tery
pa dding of the front passenger seat cushion
that measures the total weight on the seat .
The informat ion registered is sent continu­
ously to the electronic control unit to regu­ late deployment of the front Advanced Air­
bag on the passenger side .

,&. WARNING
D amage to the fron t passenger seat can
p revent the fro nt airbag from wor king
properly.
- I mp roper repai r or d isassembly of the
front passenge r and dr ive r sea t will pre­
vent the Advanced Air bag System from
functioning p roperly.
- Repairs to the front passenge r seat m ust
be pe rformed by qualifie d and p roperly
trained workshop personnel.
- Never remove the front passenger o r
d river seat from t he 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 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 .
Airbag system 117
-If the PASSENGER AIR BAG OFF light
does not come on and stay on, the inflat­
ing 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, door or roof. Have
the airbag system inspected immediately 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 Adv a 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

124 Airbag system
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 strut s, 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 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 .
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
latched or not .
If the safety belt is being used,
the front airbag will deploy at a slightly high­ er rate of vehicle deceleration than if the safe­
ty belt is not being used. Therefore, in a par­
ticular collision, it is possible that an airbag
will not deploy at a seating position where the
safety belt is being used but will inflate at the
position where the safety belt is not being
used.
It is important that nothing interfere
with the safety belt buckles so that the sen­
sors can send the correct information about
safety belt use to the electronic control unit .
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 installed on your vehicle.
- Never use tire-rim combinations that
have not been approved by Audi.
A WARNING
-Items stored between the safety belt
buckle and the center console can cause
the sensors in the buckle to send the
wrong information to the electronic con­
trol module and prevent the Advanced Air­
bag System from working properly.
- Always make sure that nothing can inter­
fere with the safety belt buckles and that
they are not obstructed.
Knee airbags
· Description of knee airbags
The knee airbag system con provide supple­
mental protection to properly restrained
front seat occupants.
Fig. 124 Drive r's airbag
The driver knee airbag is in the instrument
panel underneath the steering wheel
~ fig . 124, 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 lower
thigh areas as a supplement to the protection
by the safety belts.
If the front airbags deploy, the knee airbags
also deploy in frontal collisions when the de­
ployment threshold stored in the control unit
is met
~ page 118, More important things to
know about front airbags.
In addition to their normal safety function,
safety belts help keeping the driver or front
passenger in position in a frontal collision so ..,.

Side airbags
Description of side airbags
The airbag system can provide supplemental
protection to properly restrained front seat occupants .
Fig. 12 6 Side a irbag locat ion in t he d river 's seat
The s ide a irbags are located in the sides of the
front sea t backrests ¢
fig. 126 facing the
doors. They are identified by the word "AIR­
BAG".
The side airbag sy stem ba sic ally con sis ts of:
- th e e lectronic control module and exter nal
s ide impact senso rs
- the two side airbags located in the sides of
the front backrests
- the a irbag warning light in the instrument
cluster .
The airbag system is monitored electron ically
to make certain that it is functioning properly
at all times . Each time you turn on the igni­
tion, the airbag system indicato r light will
come on fo r a few seconds (self diagnosti cs) .
The s ide airbag system supplements the safe­
ty belts and can help to reduce the risk of in­
jury to the dr iver's and front passenger's up­
pe r torso and head inj uries on the side of the
veh icle tha t is s truck i n a side collision . The
ai rbag dep loys only in side impacts and only
when the vehicle acceleration registered by
the cont rol unit is high e nough . If t his rate is
be low the reference va lue programmed into
the control unit, the side airbags will not be
tr iggered, even though the car may be badly
damaged as a result of the co llision .
It is not
possible to def ine an a irbag tr igger ing range
A irba g sy stem 12 7
that will cove r every possib le ang le of impact,
since the circumstances wi ll vary cons iderably
between one co llision and another. Important
factors include, for examp le, the nature (hard
or soft) of the impacting object, the angle of i mpact, vehicle speed, etc. ¢
page 128, Im ­
portant safety instructions on the side airbag system .
Aside from their normal safety function, safe­
ty belts work to help keep the drive r or front
passenger in position in t he event of a side
collision so that the side airbags ca n provide
protection .
The airbag system is
not a substitute for your
safety belt . Rather, it is part of the overall oc­
cupant restra int system in your vehicle . A l­
ways remember that the side airbag system
c an on ly help to pro te ct yo u if you are wearing
your safe ty be lt and wea ring i t properly. This
is another reason why you should always wear
your safety be lts, not just because the law re­
quires you to do so¢
page 102, Why safety
belts? .
It is important to remember that wh ile the
supplementa l side airbag system is designed
to reduce the likelihood of ser ious injuries,
other injur ies, for example, swelling, bru ising,
and minor abrasions can also be associated
with deployed side airbags . Remember too ,
s ide a irbags will deploy only once and only in
ce rtain kinds of accidents -your safety belts
a re a lways the re to offer p rotection .
Vehicle damage, repair costs o r even t he lack
of ve hicle damage are not necessa rily a n in d i­
cation of ove r-s ensitive o r failed airbag activa­
t ion. In some col lisio ns, both front and side
airbags may in flate. Remember too, that air­
bags will deploy only once and on ly in ce rtain
k inds of co llisions -yo ur safety belts are a l­
ways the re to offer protection in those acci­
dents in which airbags are not supposed to
deploy or when they have a lready deployed .
The side airbag sy ste m will not deploy:
- when the ignit ion is turned off
- in side co llisions whe n the a ccelera tion
meas ured by t he sensor is too low
