Active rollover
protection system
Function
The active rollover protection system helps
protect vehicle occupants in the event of a rollover.
Fig. 104 Rollbar deployme nt range
Fig . 105 Rollbar deploye d
The active rollover protection system consists
of:
- two rollbars
- the safety belts with belt tens ioners
- th e windshield frame
- the rollover sensors .
The active rollover protection system provides
additional safety in the event of a rollover.
With in milliseconds, sensors deploy two roll­
bars located behind the headrests
c> fig. 105.
The rollbars, reinforced windshield frame and
belt tensioners help protect vehicle occupants
in the event of a rollover.
Driving Safely 101
The rollover protection system functions
when the convertible top is both open and
closed.
_& WARNING
Do not use the area behind the headrests
c> fig. 104 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 propelled
through the vehicle and make it more diffi­
cult for the rollbars to deploy. This increas­
es the risk for serious or life-threatening
injuries.
When is rollover protection deployed?
Rollover protection deploys in a collision or
rollover.
Depend ing on the collision, sensors through­
out the vehicle and the control module trigger
the rollover system to deploy.
For safety reasons, rollover protection also de­
ploys during front, side and rear collisions
above a certain level of sever ity.

& WARNING
Improperly worn safety belts increase the
risk of serious personal injury and death
whenever a veh icle is being used.
- Always make sure that all vehicle occu­
pants are correctly restrained and stay in
a correct seating posit ion whenever the
vehicle is be ing used.
- Always read and heed all WARNINGS and
other important information
Qpage 105.
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 safe ty belts for the front seating positions
a re eq uipped with safety belt pretensioners.
The system is activated by sensors in front,
side and rear-end collisions and in a rollover of
great severity. This tightens the be lt and takes
up belt slack
c> .& in Service and disposal of
safety belt pretensioner on page 109.
Tak ing
up the slack helps to reduce forward occupant movement dur ing a coll is ion.
(Di Tips
The safety be lt 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 pretens ioners are not activated .
- When the safety belt pretensioner is ac­
tivated, a fine dust is released . This is
no rm al and is not caused by a fi re in the
vehicle.
- The relevant safety requirements must
be obse rved when the vehicle or compo­
nen ts of the system are scrapped. An au­
thorized Audi dealer is familiar w ith
these reg ulations and w ill be pleased to
pass on the information to you.
Safety belts 109
- Be sure to observe all safety, envi ron ­
menta l and other regu lations if the vehi­
cle or ind ividual parts of the system, par­
t icu larly the safety belt or airbag, are to
be disposed. We recommend you have
your authorized Audi dealer perform this service fo r you .
Service and disposal of safety belt
pretensioner
The safety belt pretensioners are parts of the
safety belts on your Audi . Insta lling, remov­
ing, servicing or repairing of be lt pretension­
ers can damage the safety belt system and
prevent it from working correctly in a co lli­
s ion.
There are some important t hings you have to
know to make sure that the effectiveness of
the system w ill not be impaired and that dis­
carded components do not cause injury or pol­
lute the environment .
& WARNING
Improper care, servic ing and repair proce­
dures can increase the risk of pe rsonal in­
jury and death by preventing a safety belt
pretensioner from activating when needed
or activating it unexpectedly:
- The belt pretensione r system can be acti­
vated only once. If be lt pretensioners
have been activated, the system m ust be
replaced .
- Never repair, adjus t, or change any parts
of the safety be lt system .
- Safety belt systems incl uding safety belt
pretensioners cannot be repaired. Spe­
cial procedures are required for removal,
installation and disposal of this system.
- For any wo rk on the safety be lt system,
we strongly recommend that you see
your authorized Audi dealer or qualif ied
technician who has an Audi approved re­ pa ir manual, train ing and spec ial equ ip­
ment necessary .

Always rem emb er: Please be sure to read the
important information in the sections that
follow and be sure to heed all of the WARN ­
INGS.
A WARNING
T o reduce the risk of injury when an ai rbag
inflates, a lways wear safety belts prope rly.
- If you are unrestrained, lean ing forward,
sitting sideways or out of position in any
way, your risk of inj ury is much higher.
- You w ill also receive serious inju ries and
cou ld even be killed if you are up against
the a irb ag or too close to it whe n it in­
flates - even with an Advanced Airbag
¢page 111 .
.&_ WARNING
-
A child in a rearward-facing child safety
seat installed on the front passenger seat
w ill be seriously injured and can be k illed if
the front a irbag inf lates - even with an Ad­
vanced Airbag System.
- Although the Advanced Airbag System in
your vehicle is designed to turn off the
front a irbag when a rearward-fac ing
child restraint has been installed on the
front passenger seat, nobody can abso­ l u te ly guarantee that deployment is im­
poss ible in al l conceivable situations th at
may happen d uring the useful life of your
vehicle.

.&_ WARNING
I f, in except iona l circumstances, you must
install a forward -facing child restraint on
the front passenger's seat:
- Always make sure the forward -facing
seat has been designed and certified by its manufacturer for use on a front seat
with a passenger front and s ide a irbag.
- Never put the forward-facing child re ­
straint up against or very near the instru­
ment panel.
- Always move the passenger seat into its
rea rmost pos ition in the seat's fore and
aft ad justment range, as far away from
the airbag as possible, before installing
the forward-fac ing ch ild restra int. The
backrest must be ad justed to an upright
position.
- Ma ke sure that the

Advanced Airbag System components
T he front passenge r seat in yo ur vehicle has a
lot of very important parts of the Advanced
Airbag System in it . These parts include the
weight-sensing mat, sensors, wiring, brack­ ets, and more. The funct ion of the system in
the front passenger seat is checked by the
electronic control unit when the ignition is on .
The cont rol unit monito rs the Advanced A ir­
bag System and turns the airbag indicator
l igh t on when a malfunct ion in the system
•
•

118 Airbag system
components is detected. The function of the
airbag indicator light is described in greater
detail below. Because the front passenger
seat contains important parts of the Ad­
vanced Airbag System, you must take care to prevent 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 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 Air­ bag 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 "decides" whether the safety belt
pre tensioners should be activated.
- An Advanced Ai rbag with gas generator for
the driver inside the steering wheel hub.
- An Advanced Airbag with gas generator in­
side the inst rument panel for the front pas­
senger.
- A weight-sensing mat under the upholstery
padding of the front passenger seat cushion
that measures the total weight on the seat.
The information registered is sent continu ­
ously to the electronic control unit to regu­
late deployment of the front Advanced Air­
bag on the passenger side.
- An airbag monitoring system and indicator
light in the instrument cluster
¢page 121.
- The PASSENGER AIR BAG OFF light comes
on and stays on in the center of the instru­
ment panel ¢
page 122, fig. 120 and tells
you when the front Advanced Airbag on the passenger side has been turned off.
- A sensor below the safety belt latch for the
front seat passenger to measure the tension
on the safety belt. The tension on the safety
belt and the weight registered by the
weight-sensing mat help the control unit "decide" whether the front airbag for the front passenger seat should be turned off or
not
¢ page 112, 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 informa tion to the
electronic control unit .
.&_ WARNING
Damage to the front passenger seat can
prevent the front airbag from working
properly.
- Improper repair or disassembly of the
front passenger and driver seat will pre­
vent 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 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 .,..

restraints 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 add itional padd ing will prevent
the weight-sens ing mat in the seat from
accurately reg istering the ch ild restra int
or person on the seat and preve nt the
Advanced Airbag System from func tion­
ing properly .
- If you must use a child restra int on the
front passenger seat and the ch ild re­
straint manufacturer's instructions re­
quire the use of a towel, foam cush ion or
something else to properly position the
child restraint, make certa in that the
PASSENGER AIR BAG OFF light comes
on and stays on whenever the child re­
st ra int is installed on the front passen­
ger seat .
- If the
PA SSE NGER AIR BAG OFF light
does not come on and stay on, have the
airbag system inspected by your Audi dealer.
How the Advanced Airbag System
components work together
The front Advanced Airbag System and the side airbags s upplement the protection of­
fered by the front three-point safety be lts
with pretensioners and load limiters and the
adjustab le head restra ints to he lp reduce the
risk of injury in a wide range of acc ident and
crash situat ions . Be sure to read the impor­
tant information about safety and heed the
WARNINGS in this chapter .
Deployment of the Advanced Airbag System
and the act ivat ion of the safety be lt preten­
sioners depend on the dece le rat ion measured
by the c rash sensors and registered by the
e lectronic control un it . Crash severity depends
on speed and dece leration as well as the mass
and stiffness of the vehicle or object involved in the crash .
Airbag system 119
When the electronic control unit registers a
low severity cras h and the safety belt is being
used, the airbag will not dep loy. If the safety
belt is not being used, the first stage deploys,
followed by the second stage after a much lat­ er t ime in the crash sequence.
If the electron ic 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 be ing
used or not . In higher sever ity crashes as reg­
iste red by the elect roni c cont rol unit, bot h the
first and se cond s tages deploy almost at the
same t ime.
On the passenger side, regardless of safety
belt use, the airbag w ill be tu rned off if the
weight on the passenger sea t is less than the
amount programmed in the electronic control
u nit . The front airbag on the passenger side
will a lso 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
PASS ENGER A IR
BAG OFF light comes on and stays on to tell
you when the front Adva nced A irbag on the
passenger side has been turned off
¢ page 112, Child restraints on the front seat
- some important things to know .
_&. WARNING ~
To reduce the risk of inj ury when an a irbag
inflates, always wear safety be lts properly.
- If you are unrestrained, leaning forward,
sitting sideways or o ut o f position in any
way, your risk of injury is m uch higher.
- You will a lso receive serious injuries and
could even be killed if yo u are up against
the airbag or too close to it when it in­
f lates -even with an Advanced A irbag

-The inflating airba g will hit the child
safety seat or infant carrier wit h great
f o rce and w ill smash t he ch ild safety seat
and child aga inst the backrest, cente r
arm rest, d oor or roof.
- Never install a r earward facing child
sa fety seat on the front pass eng er s eat
unless the
PASSENGER AIR BAG OFF
light c omes on and stays on. If the PAS­
S ENGER AIR BAG OFF
ligh t does no t

will hit the child safety seat or infant car­
rier 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 .
A WARNING
Objects between you and the a irbag will
increase the risk of injury in a crash by in­
terfering with the way the airbag unfolds
or by being 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 front passenge r seat. Objects
cou ld move into the area of the front air­
bags dur ing braking or other s udden ma­
neuver and become dangerous projec ­
ti les that can cause serious personal in­
jury if the airbags inflate.
- Never place o r attach accessories or oth­
er objects (such as cup ho lders, tele­
phone brackets, large, heavy or b ulky ob­
jects) on the doors, over or near the area
marked "AIRBAG" on the steering wheel,
instrument panel, seat backrests or be­
tween those a reas and yourself. These
objects could cause injury in a crash, es­
pecially when the airbags inflate.
- Never recline the front passenger's seat
to transport objects. Items can also
move in to the area of the side airbag or
the front airbag dur ing braking or in a
sudden maneuver . Objects near the air -
-

bags can become projectiles and cause
inju ry, partic ularly when the seat is re­
clined.
A WARNING
The fine dust created when airbags deploy
can cause breathing prob lems for people
with a history of asthma or other breath­
ing cond itions.
- To reduce the risk of breath ing problems,
those with asthma o r other respiratory
conditions shou ld get fresh air r ight
away by getting o ut of the veh icle or
open ing windows or doors.
- If you are in a collision in which airbags
deploy, was h your hands and fa ce with
mild soap and wate r before ea ting.
- Be ca reful not to get the dust into your
eyes, o r into any cuts or sc ratches .
- If the resid ue should get into your eyes,
f lush them w ith wate r.
