Advanced Airbag System components
The front passenger seat in your vehicle has a
l ot of very important parts of the Advanced
Ai rbag System in it. These parts incl ude the
capacitive passenger detect ion system, wir ­
i n g, brackets, and more . The control unit
monitors the system o n the front passenger
seat when the ign ition is switched on and
turns the airbag indicator light on when a
malfunct ion in the one of the system compo­
nents is detected ¢ page
152 . Because the
fro nt passenger seat contains important parts
of the Advanced Airbag System, you must
t ake care to p reven t it from being damaged.
D amage to the seat may preven t the Ad­
vanced A irbag 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 o f the veh icle that
measure vehicle acceleration/dece leration
to provide information to the Advanced Air­
bag System about the severity of the crash .
- An electronic co ntrol unit, with integrated
crash sensors for front and side impacts .
The contro l unit "decides" whether to fire
A irbag system 147
the front a irbags based on the in format ion
received from the crash sensors. The contro l
unit also "decides" whether the safety be lt
pretens ioners sho uld be activated .
- An Advanced Airbag with gas generator and
contro l valve for the driver ins ide the steer­
ing wheel hub.
- An Advanced Airbag with gas gene rator and
cont ro l valve inside the instrument pane l for
the front passenger.
- A capacitive passenger detection system un­
derneath the front passenger seat cover.
This system measures the electrical capac i­
tance of the person in the seat. The informa­
tion registered is se nt cont inuously to the
el ectr onic contro l un it to regu late deploy­
ment of the front Advan ced A irbag on the
passenger side .
- An airbag monitoring system and ind icator
light in the instr ument cluster ¢page
151 .
-A sensor in each front seat registers the dis­
tance be twee n the respec tive seat a nd the
s teer ing whee l or inst rument p anel. The i n­
forma tion regis tered is sent cont inuo usly to
the electronic cont ro l unit to regulate de­
p loyment of the front Adv a need Airbags.
- The
PASSENGER AIR BAG OFF light comes
on and stays on in the center of the instr u­
ment panel ¢ pag e
152, fig. 162 and tells
you when the front Advanced Airbag on the passenger side has been turned off.
- A sensor in the safety belt latch for the driv­
er and for the front seat passenger that
senses whether that safe ty belt is latched or
not and transmits this information to the

sudden maneuver. Objects near the
airbags can become projectiles and cause
injury, particularly 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 the seat is occupied
by a person whe n it in fact is not, o r that
the person on the sea t is heavier than he
o r she actually is. The change in electric
capacitance beca use of such objects can
cause the passenger front airbag 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 objects on the seat.
- Always make sure that there is nothing
on the front passenger seat that will
cause the capacitive passenge r detection
system in the seat to s ignal to the A irbag
System that t he seat is occupied by a
pers on when it is not, or to sign al tha t it
is occupied by someone who is heavier
than the pe rson actually sitting on the
seat . The presence of an object co uld
cause the passenger front a irbag to be

Monitoring the
Advanced Airbag
System
tli Airbag monitoring indicator light
Two seporate indicators monitor the function
of the Advanced Airbag System: the airbag
monitoring indicator light and the
PASSEN ­
GER AIR BAG OFF light.
The Advanced Ai rbag System (incl uding the
electronic control unit, sensor circu its and sys­
tem wir ing) is mo nitored continuously to
make sure that it is funct io ni ng properly
whenever the ignition is on. Each time you
switch on the ignition, the airbag monitor ing
i ndica to r li ght
fl will come on for a few sec­
onds (self diagnos tics).
The system must be inspected when the
indicator light
ffl:
- does not come on when the ignition is
sw itched on,
- does not go out a few seconds after you
have sw itched on the ignit io n, or
- comes on whil e driv ing .
If an airbag system malfunction is detected,
the indicator lig ht w ill first sta rt flash ing to
catch the driver's attent io n and then stay on
continuously to serve as a co nstant rem inder
to have the system inspected immediately.
If a malfu nction occurs that turns the front
airbag on the passenger s ide off, the
PASSEN­
GER AIR BAG OFF light will come on and stay
o n wheneve r th e ignit io n is on.

chlorate. When the vehicle or parts of the
restraint system including 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 service 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-rim 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 electronic 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 installed on your vehicle.
- Never use tire-rim combinations that
have not been approved by Audi.
Knee airbags
Description of knee airbags
Applies to vehicles: with knee airbags
The knee airbag system can provide supple­
mental protection to properly restrained
front seat occupants .
Fig. 163 Driver 's knee airbag
The driver knee airbag is in the instrument
panel underneath the steering wheel
¢ fig. 163, 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 149, 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 belt and wearing it properly. This
is why you should always wear your safety
belt, not just because the law requires you to
do so

caused by airbags when they inflate, particu­
l arly when the occupant sitting next to it is
not seated properly. The s ide a irbag for the
front passenger seat can be used with proper­ ly installed chi ld restraints. Please be sure to
read the important information and warnings
whenever us ing a child restraint in a veh icle :
Safety belts

The side airbag system basically con sists of:
- the e lectronic control module and external
s ide impact sensors
- the two airbags located in the sides of the
front backrests and the two airbags* located
in the rear backrest
- the airbag warning light in the instrument
cluster.
The airbag system is monito red elect ron ica lly
to make certain that it is functioning properly
at all times. Each time you switch on the igni­
tion, the airbag system indicator light will
come on for a few seconds (self diagnostics) .
T he 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 passenger's upper torso on t he side of the vehicle that is
struck in a side collision . The airbag deploys
only in s ide impac ts and on ly when the veh icle
acceleration registered by the control u nit is
hi gh enough . If this rate is below the refer­
e nce va lue progr ammed i nto the con trol un it,
the side airbags will not be triggered, even
though the ca r may be badly damaged as a re­
sult of the collision . It is not possible to de­
f ine an a irbag trigger ing range that will cover
eve ry possible angle of impact, since the cir­
cumstances will vary considerably between
one co llision and another . Important facto rs
in clude, for examp le, the natu re (hard o r soft)
of the impacting objec t, the ang le of impact ,

collision so that the side airbags can provide
protection.
T he airbag system is
not a substi tute fo r your

Vehicle damage, repair costs o r even the lack
of ve hicle damage are not necessarily a n indi­
cation of ove r-sensitive or failed airbag activa­
tion. In some coll is ions, both front and side
a irbags may inflate. Remember too, that air­
bags will deploy only once a nd only in certain
ki nds of col lisions - you r safety belts a re a l­
ways t he re to offe r protection in those acc i­
dents i n 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 io n is switched off
- in side co llisions whe n the acceleration
meas ured by t he sensor is too low
- in front-end collisions
- in rear -end co llisions
- in rollove rs .
In some types of accidents the front airbags,

-Never use additional seat cushions that
cover the areas where the side airbags
deploy.
- Damage to the original seat covers or
to the seam in the area of the side air­
bag module must always be repaired
immediately by an authorized Audi
dealer .
- 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 deployment 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.

- 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

Side curtain airbags
Description of side curtain a irbags
The side curtain airbag system can provide
supplemental protection to properly restrain­
ed occupants.
Fig. 167 Sid e curta in airbag s, driver's sid e: s ide curta in
airbag locatio n ....

162 Airbag sys tem
The side curtain airbags are located on both
sides of the interior above the front and rear
side windows ~
fig. 167. They are ident ified
by the word "AIRBAG" on the windshie ld
frame and the center roof p illar.
The side curtain airbag system supp lements
the safety belts and can help to reduce the
risk of injury for occupants' heads and upper
torso on the side of the vehicle that is struck
in a side co llision . The side curtain airbag in­
flates in s ide impacts and only when the veh i­
cle acce lerat ion reg istered by the contro l unit
is high enoug h. If th is rate is below the refe r­
ence va lue programmed i nto the control un it,
the side curtain airbag wi ll not be triggered,
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
circumstances will vary cons iderably between
one co llision and another. Important factors
i nclude, for example, the nature (hard or soft)
of the impacting object, the ang le of impact,
vehi cle speed, etc.
~ page 163, How side cur­
tain airbags work.
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 co lli­
sion so that the side curta in airbags can pro­
vide protection.
The airbag system is not a subst itute for you r
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 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
Q page 130, General
notes.
It is important to remember that while the
side curta in a irbag system is designed to help
reduce the likelihood of serious injuries, other
injuries, for example, swell ing, bruisi ng, fric ­
tion burns and m ino r abrasions can also be as­
sociated with these a irbags upon deployment.
Remembe r too, these airbags w ill dep loy only once and on
ly in certain kinds of accidents -
your safety belts are always there to offer pro­
tection.
The side curtain a irbag system basically
con sists of :
-The e lectronic control module and external
side impact sensors
- The side curtain airbags above the front and
rear side windows
- The airbag indicator light in the instrument panel
T he airbag system is mon itored e lectronically
to make ce rtain i t is func tioning prope rly at all
times . Each time you switch on the ignition,
the airbag system indicator light will come on
for a few seconds (self diagnostics).
The side curtain airbag i s not activated :
-if the ignition is sw itched off,
- in side co llisions when the acceleration
measured by the se nsor is too low,
- in rear-end col lisions.
_&. WARNING
- Safety belts and the airbag system will
only provide protection when occupants
are in the proper seating posi tion
¢ page 53, General recommendations.
- If the ai rbag ind icator light Q page 18
comes when the veh icle is being used,
have the system inspected immediately
by your authorized A udi dealer. It is pos­
sible that the airbag will inflate when it
is not supposed to, or will not inflate
when it should.

184 Audi pre sense
Audi pre sense
Preventative passenger
protection
A pp lies to veh icles: with Audi pre se nse
Audi pre sense can initiate steps to help pro­
tect vehicle occupants in certain situations.
The functions described depend on equ ipment
installed in your vehicle:
Audi pre sense basic*
The following functions can be triggered in
certain driving situations:
- Tightening of the safety belts (for example,
during heavy braking) : the front safety belts
have reversible belt pretensioners. If a colli­
sion does not occur, the safety belts loosen
slightly and are ready to be tightened again.
- Closing the windows and the sunroof*: the
windows and the sunroof* close leaving a
small open gap.
Audi pre sense basic functions can be trig­
gered at speeds above 20 mph (30 km/h).
Vehicles with Aud i drive select*: the deploy­
ment time is adapted in
Dynamic mode.
Audi pre sense front (vehicles with
adaptive cruise control*)
Audi pre sense front includes the functions in
Audi pre sense basic. In addition, within the
limits of the system, the likelihood of a colli ­
sion with the vehicle immediately ahead is al­
so calculated . If the system senses an immi­
nent collision the following functions can be
tr iggered :
- Braking guard c::>poge
87
-Tightening the safety be lts
- Closing the windows and the sunroof* (leav -
ing a small open gap)
Audi pre sense rear (vehicles with Audi
side assist*)
Audi pre sense rear includes the functions in
Audi pre sense basic. In addition, the likeli­
hood of a rear-end collision with the vehicle
coming from behind is also calcu lated.
If the risk
of a co llision is detected, the following
functions can be triggered:
- Tig htening the safety belts
- Closing the windows and the sunroof* (leav-
ing a small open gap)
Audi pre sense plus*
Audi pre sense plus includes the functions in
Audi pre sense front and Audi pre sense rear.
Error message
Audi pre sense: not available
Preventative passenger protection is not avail­
able. See your authorized Audi dealer immedi­
ately to have the malfunction corrected.
_& WARNING
-=
Audi pre sense cannot overcome the laws
of physics. It cannot prevent a collision. Do
not let the increased safety provided
tempt you to take risks. This will increase
the r isk of a collis ion and serious personal
in juries .
- The sensors cannot always detect all ob­
jects. This increases the risk of a colli­
s10n.
-Aud i pre sense does not detect people or
an im als or objects that are crossing the
veh icle's path c::> page
81.
-The radar sensor's vis ion can be reduced
by heavy rain, ice, snow, heavy road sp ray
and reflections from guard rails, tunnel
entrances, etc. These and similar condi­
tions can prevent vehicles from being ac ­
curately detected and in some cases they
may not be detected at all.
(D Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. This can affect the function of
the Audi pre sense system. Have your au­
thorized Audi dealer check to make sure
that the system is working properly.

194 Intelligent technology
Basically, energy management consists o f
battery di agno sis, idling current manage­
ment
and dyn ami c ene rg y m anagement.
B attery diagno sis
Battery d iagnosis continuously dete rm ines
the state of the battery. Sensors determ ine
battery vo ltage, battery current and battery
temperature. This determines the current
state of charge and the power of the battery.
Idling curr ent mana gem ent
Idling c urrent management reduces energy
consumption while the vehicle is standing.
With the ignition switched off, it contro ls the
energy s upply to the various e lectrica l compo­
nents . Data from battery diagnosis is consid­
ered.
D epending on the battery's state of charge,
individual consumers are gradually turned off
to prevent excess ive d ischarge of the battery
and thus mainta in start ing capability.
Dynamic en erg y managem ent
While the vehicle is being dr iven, dynamic en ­
ergy management distributes the energy gen­
erated according to the needs of the individu­
a l components. It reg ulates cons umption, so
that more electrical energy is not being used
than is being generated and ensures an opti­
mal state of charge for the battery.
(D) Tips
- But even energy management cannot
negate the limits of physics. Consider
that the power and life of a battery are
li mited.
- If starting ab ility is threatened, t he indi­
cator
light (•i appears ~page 16.
What you should know
The highest priority is given to maintaining
starting capability.
The battery is severely taxed in short-distance
driving, in city traffic and during the co ld time
of year. Abu ndant e lectr ical energy is re- quired, but on
ly a little is generated .
It is also
critica l if the engine is not r unning and electri­
ca l components are turned on. In this in­
stance energy is be ing consumed but none is
being generated .
It is in precise ly these situations that you will
notice energy management active ly regu lat­
ing the d istribution of energy.
V ehicle stand s for an e xtended period
If you do no t drive your vehicle over a period
of several days or weeks, e lectrica l compo ­
nents a re g radually cut back or switched off .
This reduces energy consumption and main­
ta ins start ing capability over a longer period .
Some of the convenience functions may not
operate, such as the interior l ights or the
