- make sure that the convertible locking fea­
ture on the safety be lt for the front passen­
ger seat has been activated and that the
safety belt has been pulled tight. The belt
must not be loose or have loops of slack so
that the sensor below the safety belt latch
on the seat can do its job<=>
page 138 .
-make sure that th ings that may increase the
weight of the child and child safety seat are
not being transported on the front passen­
ger seat;
- make sure that the safety belt tension sen­
sor is not blocked . Shake the safety belt
latch on the front passenger seat back and
forth;
- If a strap or tether is being used to tie the
ch ild safety seat to the front passenger
seat, make sure t hat it is not so tight that it
ca uses the we ight-sensing mat to meas ure
more weight than is actua lly on the seat .
If the PASSENGER AIR BAG OFF light still
d oes no t com e on and does not stay on con­
tinuously (when the igni tion is sw itched on),
- take the ch ild restraint off the front passen·
ger seat and have the airbag system inspect­

Important safety instructions on
monitoring the Advanced Airbag System
A WARNING
-
An airbag system that is not functioning
p roperly cannot provide supplemental pro­
tection in a frontal c rash.
- If the airbag ind icator light comes on, it
means that there may be something
wrong with the Advanced Airbag Sys tem.
It is poss ible that the ai rbag w ill inflate
when it is not supposed to, or will not in­
f late when it sho uld .
- Have the airbag system inspe cted imme­
diate ly by your Audi dealer.
A WARNING
If the front airbag inflates, a child withou t
a child restraint, in a rea rward-facing child
safety seat or in a forwa rd-facing child re­
straint that has not been properly installed
will be ser ious ly injured and can be killed.
- Even tho ugh your vehicle is equipped
with an Advanced A irbag System, make
certain that all children, espec ially 12
yea rs and younger, always ride properly
restrained fo r their age and size. •
•

122 Airbag sys te m
- If you must install a rearward facing
child safety seat on the front passenger
seat because of exceptional circumstan­ ces and the
PA SSEN GE R AIR BA G OFF
light does not appear and stay on have
the a irbag system inspected by your Audi
dealer.
- A tight tether or other strap on a rear­
ward-fac ing child restra int attached to
the front passenger seat can put too much pressure on the weight-sens ing
mat in the seat and register more weight
than is actually on the seat. The heavier
weight registered can make the system
work as though an adu lt were on the seat
and deploy the Advanced Airbag when it
must be suppressed caus ing serious or
even fatal injury to the child.
- If, in exceptional circumstances, you
must install a forward-facing child re­
straint on the front passenger seat, al­
ways move the seat into its rearmost po­ sit ion in the seat's fo re and aft adjust­
ment range, as far away from the airbag
as possib le . The backrest m ust be adjust­
ed to an upright position. Make sure that
the
PASSENGER AIR BAG OFF light
comes on and stays on all the t ime when­
ever the ignition is switched on.
A WARNING
- If the PASSENGER AIR BAG OFF light
does not go out when an adult is sitting
on the front passenger seat after taking
the steps described above, have the air­ bag system inspec ted by your Audi deal­
er before transporting anyone on the
front passenger seat.
(D Tips
If the weight-sensing mat in the front pas­
senger seat detects an empty seat, the
front airbag on the passenge r side will be
turned off, and
PASSENGER AIR BAG OFF
w ill stay on.
Repair, care and disposal of the airbags
Pa rts of the airbag system are i nstalled at
many diffe rent p laces o n your Aud i. Insta llin g,
removi ng, servicing or repa iring a part in an
area of the veh icle can damage a part of an
airbag system and prevent that system from
working properly in a coll is ion.
T he re a re some important t hings you have to
k now to make sure that the effectiveness o f
t h e system wi ll not be impaired and that dis­
carded components do not cause injury or pol ­
l ute the environment.
A WARNING
Improper care, serv ic ing and repair proce­
dures can increase the risk of personal in­
j u ry and death by prevent ing an a irbag
from deploying when needed or dep loying
an a irbag unexpec tedly:
- Never cover, obst ruct, or change the
steer ing whee l horn pad or ai rbag cover
or the in st rument panel or mod ify them
in any way .
- Never attach any obje cts s uch as c up
holders or telephone mountings to the
sur faces covering the a irbag un its.
- For cle aning the horn pad or instr ument
panel, use only a soft, dry clo th or one
moistened with pla in water. Solvents o r
cleaners could damage the airbag cover
or change the st iffness or strength of the
material so that the airbag cannot de­
p loy and protect properly.
- Never repair, adjust, or change any parts
of the a irbag system.
- All work on the steering wheel, instru­
ment panel, front seats or e lectr ica l sys­
tem (including the installation of audio
equ ipment, cellu lar telep hones and CB
radios, etc.) must be performed by a
qualified technic ian who has the training
and specia l equipment ne cessary.
- For any wo rk on the airbag system, we
strongly recommend that you see your
author ized Audi dealer or qualified work-
shop. ..,.

-Never modify the front bumper or parts
of the veh icle body.
- Always make sure that the side airbag
can inflate without interference:
- Never install seat covers or replace­
ment upho lstery ove r the front seat­
backs that have not been spec ifically
approved by Audi.
- Never use add itiona l seat cushions that
cover the areas where the side airbags
inflate .
- Damage to the o rigina l seat covers or
to the seam in the area of the side air­
bag module must always be repa ired
immediate ly by an authorized Audi
dealer.
- The airbag system can be activated only
once . After an airbag has inflated, it
must be replaced by an author ized Audi
dealer or qualif ied technic ian who has
the techn ica l information, tra ining and
special equipment necessary.
- The airbag system can be deployed only
once. After an a irbag has been deployed,
it must be replaced w ith new replace­
ment parts designed and approved espe­
c ially for your Aud i model version. Re­
placeme nt of complete ai rbag systems
or airbag componen ts m ust be per­
f ormed by qualified workshops only.
Make su re that any airbag service act ion
is entered in your Audi Warranty
& Main­
tenance booklet under
AIRBAG REPLACE­
MENT RECORD.
- For safety reasons in severe accidents,
the a lternator and starter are separated
from the vehicle battery with a pyrotech­
nic circuit interrupter.
- Wo rk on the pyrote chnic cir cu it inter­
rupter must on ly be per formed by a
qualified dealer - risk of an accident!
- If the veh icle or the ci rcuit interrupter
is sc rapped, all applicable safety pre ­
cautions must be followed .

tir e-rim combi nat ions not approved by A udi,
l ower ing the veh icle, chang ing the st iffness of
the suspens ion, including the spr ings, suspen ­
sion struts, shock absorbers etc. can change
the forces that are measured by the airbag
sensors and sent to the electronic contro l
u nit. Some suspension changes can, for exam­
ple, i ncrease the force levels measured by the
sensors and make the airbag system deploy in c rashes in which it wou ld not deploy if the
c h anges had not been made. Other kinds of
c h anges may reduce the fo rce leve ls meas­
ur ed by the sensors and preven t the airbag

,&. WARNING
Changing the vehicle 's suspension includ­
ing use of unapproved tire-rim combina­
tions can change Advanced Airbag per­

nally insta lled on your vehicle.
- Never use ti re-rim combinat ions that
have not been approved by Audi.
,&. 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

- 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 can provide supple­
mental protection to properly restrained
front seat occupants.
Fig. 116 Driver's airbag
The driver knee airbag is in the instrument
panel underneath the steering wheel
~ fig. 116, the airbag for the passenger is at
about the same height in the instrument pan­
el underneath the glove compartment .
T he knee airbag offe rs addi tional p rotec tion
to the driver 's and passenger's knees and up­
per and lower thigh areas and supplements
the protection by the safety belts.
If t he front a irbags dep loy, the k nee a irbags
also dep loy 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 sa fety function,
safety belts help keep the driver or front pas­
senger in position in a fronta l collision so that
the a irbags can provide supplemental protec­
t ion.
The airbag system is not a substitute for your
safety belt. Rather, it is part of the overa ll oc ­
cupant restraint system in your vehicle. A l­
ways remember that the airbag system can
only he lp to protect you if you are wearing
you r safety belt and wea ring it properly. This
is why you should a lways wear your safety
belt, not just because the law requi res you to
do so~
page 101, General notes.
The safety belt buckle for the driver and front
seat passenger have switches that tell the air­
bag control module if the safety bel t is being
u sed or not .
If the safety belt is be ing used,
t h e knee a irbag w ill deploy at a s light ly h igher
rate of dece leration than if the belt is not be ­
ing used. Therefore, in a particular co llision, it
is possib le that an airbag will not dep loy 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 .
Remember too, airbags will deploy on ly once
and only in certa in kinds of accidents - your
safety belts are always there to offer protec­
t ion in those accidents in which airbags are
not supposed to deploy o r whe n they have al­
ready dep loyed, for example when your vehi­
cl e s trikes or is st ru ck by ano ther after the
first collision . ..,.

This is just one of the reasons why an airbag is
not a substitute for the safety belt . The airbag
system works most effective ly when used with
the safety belts. Therefore, always wear your
safety belts correctly .
It is important to remember that while the
supp lemental knee a irbag system is des igned
to reduce the like lihood of serious injuries,
other injuries, for example, swel ling, bruising,
minor abrasions and friction burns can also
occur when an a irbag inflates.
The knee airb ag sy stem ba sically con sist s
of:
-The electronic contro l modu le
- Two inflatable airbags (airbag and gas gen-
erator), one for the driver and one for the
front passenger
- The airbag indicator light in the instrument
panel
The knee airbag sy stem will not d eploy :
-when the ignition is turned off
- in frontal col lisions when the dece lerat ion
measured by the control unit is too low
- in s ide collisions
- in rear-end collisions
- in rollovers
- in the event of a system malfunct ion (warn-
ing/indicator light is on)~
page 15.
A WARNING
-Safety belts and the a irbag system can
o nly prov ide protection when o ccupants
are in the proper sea ting posit ion
~page 118.
-If the airbag indicato r light comes when
t h e vehicle is being used, have the sys­
tem inspected immediately by your au ­
thorized Audi dea ler.

A irba g sy stem 125
How knee airbags work
The risk of injury to the leg area can be re­
duced by fully inflated knee airbags .
Fig . 1 17 In flated a irbags protecting in a fronta l colli ­
sion
The knee airbag system has been designed so
that the airbags for the driver and front pas­
senger deploy in certain but not all frontal
collisions .
If the front a irbags deploy, the knee a irbags
also deploy in frontal collisions when the de­
ployment threshold stored in the control unit
is met .
When the system deploys, the airbags fill
with a propellant gas, and inflate between the lower pa rt of the instrument pa nel and the
driver and the lower part of the instrument
panel and the front passenger
9 page 118,
fig. 114 .
Although they are not a soft p illow, they can
"cushion" the impact and in th is way they can
help to reduce the risk of injury to the lower
extremit ies.
All of th is takes place in the blink of an eye, so
fast that many people don't even realize that
the a irbags have deployed. The airbags a lso
inflate wi th a great deal of fo rce and it is im­
portant for occupant safety t hat no thing
shou ld be in their way when they deploy .
Fully inf lated ai rbags in combination with
properly worn safe ty be lts s low down and lim­
it the occupant's forward movemen t an d help
to reduce the risk of injury.

126 Airbag system
Important safety instructions on the
knee airbag system
Airbags are only supplemental restraints. Al­
ways wear safety bel ts correctly and ride in a
proper seating position.
There is a lot that you and your passenger
must know and do to help the safety belts and
a irbags to provide supp lemental protection.
.&_ WARNING
An inflating knee airbag can cause serious
injury. Wearing safety belts inco rrectly and
improper seating positions increase the
r isk of serious personal injury and death
whenever a veh icle is being used.
-
- The knee airbag system cannot protect
you properly if you are seated too close
to any of the airbag locations. When ad­
just ing their seat positions, it is impor­
tant that both the driver and the front
passenger keep their upper bodies and
knees at the fo llowing min imum safe
distances:
- at least 10 inches (25 cm) between the
chest and t he steering wheel/ instru­
ment panel.
- at least 4 inches (10 cm) between the
knees and the lower part of the instru­
ment panel.
- The risk of persona l injury increases if
you lean forward or to the side, or if the
seat is imp roperly posit ioned and you are
not wearing your safety belt. The r isk in­
creases even more should the airbag de­
ploy.
- Always make sure that the knee a irbag
c an in flate without interference. Obje cts
between you and the airb ag can increase
the risk of inju ry in an acc iden t by inter ­
f ering with the way the airbag dep loys or
by being pushed into you as t he a irbag
dep loys .
- Never let anybody, especially ch ild ren
or an imals ride in the footwe ll in front
of the passenger seat.
If the airbag de- ploys, this can result in serious or fatal
injur
ies.
- Never ca rry objects of any kind in the
footwell area in front of the dr iver's or
passenger 's seat. Bulky objects (shop­
ping bags, for example) can interfere
with or prevent proper deployment of
the a irbag. Small objects can be
th rown thro ugh the ve hicle if th e air­
bag deploys and injure yo u or your pas­
sengers.
- Make sure there are no cracks, deep
scr atc hes or o ther dam age in the area of
the ins trumen t panel where the knee a ir­
bags are lo cated .
- If chi ld ren are incorrectly se ated, their
ris k of injury increases in a co llision
~page 130, Child Safety.
Side airbags
Description of side airbags
The airbag system can provide supplemental
protection to properly restrained front seat
occupants.
Fig . 11 8 Side airb ag locat ion in th e drive r's seat
The side airbags are loca ted in the sides of t he
fron t seat b ackrests
q fig. 118 fa cing the
doo rs . They are identif ied by the word "A IR­
BAG".
Th e side airbag sy stem ba sic ally consi st s of:
- the electron ic contro l module and external
side impact sensors
- the two side airbags located in the sides of
the front backrests
- the airbag warning light in the instrument
cluster .

The airbag system is monitored electronically
to make certain that it is functioning properly
at all times. Each time you turn on the igni­
tion, the airbag system indicator light will
come on for a few seconds (self diagnostics) .
The side airbag system supp lements the safe­
ty belts and can help to reduce the risk of in ­
jury to the driver's and front passenger's up­ per torso on the side of the veh icle that is
struck in a side collision. The airbag deploys in
side impacts and only whe n the vehicle accel­
erat ion reg istered by the contro l unit is hig h
e nough. If t his rate is below the reference val­
ue programmed into the control u nit, the s ide
airbags w ill not be triggered, even tho ugh the
car may be badly damaged as a res ult of the
col lision . It is not possible to define an airbag
tr igger ing range that will cover every poss ible
angle of impact, since the circumstances w ill
vary cons iderably between one coll is ion and
another. Important factors include, fo r exam ­
ple, the natu re ( hard o r soft) of the impacting
object, the angle of impact, vehicle speed,
etc. Q page 128, Important safety instruc­
tions on the side airbag system.
Aside from the ir normal safety function, safe­
ty belts work to he lp keep the d river or front
passenger in posit ion in the event of a side
coll is ion so th at the s ide airb ags can provide
p rotec tion.
The airbag system is
not a substitute for your
safety belt. Rathe r, it is pa rt of the overall oc­
cup ant res traint system in your veh icle. Al­
ways remember tha t the side airbag system
can only he lp to protect you if yo u are wearing
your safety belt and wearing it properly. This
is another reason why you sho uld a lways wear
your safety belts, not just because the law re­
qu ires you to do so
Q page 101, General
notes .
It is important to remember that while the
supplemental s ide a irbag system is designed
to reduce the like lihood of serious injur ies,
other i njuries, for example, swel ling, b ruising,
and minor abras io ns can also be assoc iated
with deployed side a irbags . Remember too,
side ai rbags will deploy on ly on ce and on ly in
A irbag system 127
certain kinds of accidents -your safety belts
are a lways the re to offer p rotection.
Vehicle damage, repair costs or even t he lack
of ve hicle damage are not necessa rily an in di­
cation o f ove r-sensitive or failed airbag activa ­
tion . In some collisions, both fro nt and side
airbags may inflate . Remember too, t hat air ­
bags will deploy only once and on ly in certain
k inds of col lis ions -yo ur safety belts are al­
ways the re to offer p rotection in those acc i­
dents in which a irbags a re not supposed to
deploy or wh en they have a lready deployed .
The side airbag system will not deploy:
- when t he ignit ion is turned off
- in side co llisions when the acceleration
meas ured by the sensor is too low
- in rear -end co llisions
- in rollove rs .
In some types of accidents the front airbags
and s ide airbag s may be triggered toge ther.
.&_ WARNING
- Safety belts and the airbag system will
only provide pro tection when occupants
are in the proper seating position
Qpage 128.
- If the ai rbag ind icator light comes on
when the vehicle is being used, have the
system inspected immediately by your
author ized Audi dealer. The airbag may
not work properly when the ve hicle ac­
c e leration in a side collis ion is high
e nough to activate t he a irbag .

130 Child Safety
Child Safety
Important things to know
Introduction
The physical principles of what happens when
your vehicle is in a crash apply also to children
c::> page 102, What happens to occupants not
wearing safety belts? .
But unlike adults and
teenagers, their muscles and bones are not
fully developed . In many respects children are
at greater risk of serious injury in crashes than
adults.
Because children's bodies are not fully devel­
oped, they require restraint systems especial ­
ly designed for their size, weight, and body
structure . Many countries and all states of the
United States and provinces of Canada have
laws requiring the use of approved child re­
straint systems for infants and small children.
In a frontal crash at a speed of 20-35 mph
(30-56 km/h) the forces acting on a 13-pound
(6 kg) infant will be more than 20 times the
weight of the child. This means the weight of
the child would suddenly be more than 260 pounds (120 kg). Under these conditions,
only an appropriate child restraint properly used can reduce the risk of serious injury.
Child restraints, like adult safety belts, must
be used properly to be effective. Used improp­
erly, they can increase the risk of serious in­
jury in an accident.
Consult the child safety seat manufacturer's instructions in order to be sure the seat is
right for your child's size
c::> page 133, Impor­
tant safety instructions for using child safety
seats.
Please be sure to read and heed all of
the important information and WARNINGS
about child safety, Advanced Airbags, and the
installation of child restraints in this chapter.
There is a lot you need to know about the Ad­
vanced Airbags in your vehicle and how they
work when infants and children in child re­
straints are on the front passenger seat. Be­
cause of the large amount of important infor- mation, we cannot repeat it all here. We urge
you to read the detailed information in this
owner's manual about airbags and the Ad­
vanced Airbag System in your vehicle and the
very important information about transport­ ing children on the front passenger seat.
Please be sure to heed the WARNINGS - they
are extremely important for your safety and
the safety of your passengers, especially in­
fants and small children.
A WARNING
-
All vehicle occupants and especially chil­
dren must be restrained properly whenev­
er riding in a vehicle. An unrestrained or
improperly restrained child could be in­
jured by striking the interior or by being
ejected from the vehicle during a sudden maneuver or impact. An unrestrained or
improperly restrained child is also at great­
er risk of injury or death through contact
with an inflating airbag.
_& WARNING
Children on the front seat of any car even
with Advanced Airbags can be seriously in­
jured or even killed when an airbag in­
flates. A child in a rearward-facing child
safety seat installed on the front passen­
ger seat will be seriously injured and can
be killed if the front airbag inflates.
- The inflating 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.
- Never install a rearward facing child
safety seat on the front passenger seat
unless the
PASSENGER AIR BAG OFF
light comes on and stays on. If the PAS·
SENGER AIR BAG OFF
light does not
come on and stay on, have the airbag
system inspected immediately by your
Audi dealer.
