lower parts of the body . Front a irbags s upplement the t hree-poi nt
sa fety belts o nly in some fro ntal collis ions in which the vehicle decel­
eration is high enough to dep loy the a irbags .
Front airbags will not deploy:
• if the ignition is switched off when a crash occurs,
• in s ide collisions ,
• in rea r-end collisions,
• in rollovers,
• when the crash decelerat io n me asured by the a irbag system is less
than the min imum threshold needed for a irbag deployment as reg is­
tered by the e lectron ic con trol un it.
The front passenger airbag also will not deploy:
• when the fron t passe nger seat i s not oc cupied,
• when the weight on the front passenger seat as sensed by the
Advanced Ai rbag System in dicates that the front airbag o n the
passenger side has to be turned off by the e lectronic control unit (the
PASSENGER AIR BAG OFF li ght comes on and stays on).
& WARNING
Sitting in the wrong position can increase the ri sk of ser iou s injury
in crashes.
• To redu ce the risk of injury when the airbags inflate, the driver
and pas sengers mu st always sit in an upright position , mu st not
lean against or place any part of th eir body too close to the area
where the airbags are lo cated.
• Occupants who are unbelted, out of position or too close to the
airbag can be seriou sly injured by an airbag a s it unfolds with
great force in th e blink of an eye =>
page 199 .
Controls and equip­
ment Safety first Vehicle operation
& WARNING
A child in a rearward-facing child
safety se at installed on the front
pa sseng er seat will be seriously injured and can be killed if the
front airbag inflat es - ev en with an Ad van ced Airbag System .
• The inflating airbag will hit the child safety seat or infant
c arrier with great force and will smash the child safety s eat and
c hild against the backre st, center armre st, d oor or roof .
• Always install rear -facing child safet y seats on the rear seat.
• If you must install a rearward facing child safety seat on the
front passenger se at because of e xceptional circumstances and
the PASSENGER AIR BAG OFF light do es not come on and stay on ,
immediately install the rear -facing child s afety seat in a rear
s eating po sition and h ave the airbag system inspe cted by your
Audi d eal er.
& WARNING
Object s between you and the airbag will increase th e risk of inju ry
in a cra sh by int erfering with the way the airb ag unfold s or by
being pushed into you as the airbag inflates.
• Never hold things in your hand s or on your lap when the vehicle
i s in use.
• Never tran sport items on o r in the are a of the fr ont pa ssenger
seat. Obje ct s c ould move into the area of the front ai rbag s during
braking or other sudden maneu ver s and become dang erous
projectiles that can c au se se rious per sonal injury if the ai rb ags
infl ate.
• Never pla ce o r attach accessories or othe r objects (s u ch a s
cupholders, telephone brac kets, large , heavy or bulk y object s) on
the doo rs, over o r near the are a marked

& WARNING (conti nued)
• Never recline the front passenger's seat to transport objects.
Items can also move into the area of the s ide airbag or the front
airbag during braking or in a sudden maneu ver. Objects near the
airbags can become projectiles and cause injury, particularly when
the seat is reclined .
& WARNING
The fine dust created when airbags deploy can cause breathing
problems for people with a history of asthma or other br eathing
conditions.
• To reduce the risk of breathing problems, those with asthma or
other respiratory conditions should get fresh air right away by
getting out of the veh icle or opening windows or doors.
• If you are in a colli sion in which airbags deploy, wa sh your
hands and face with mild soap and water before eating .
• Be careful not to get the dust into your eyes, or into any cuts or
scratches.
• If the residue should get into your eyes, flush them with
water .•

Important safety instructions on
monitoring the Advanced Airbag System
& WARNING
An airbag system that is not functioning properly cannot provide
supplemental protection in a frontal crash.
• If the airbag indicator light comes on, it means that there may
be something wrong with the Advanced Airbag System.
It is
possible that the airbag will inflate when it is not supposed to, or
will not inflate when it should.
• Have the airbag system inspected immediately by your Audi
dealer.
& WARNING
• If the front airbag inflates, a child without a child restraint , or
in a rearward-facing child safety seat, or in a forward-facing child
restraint that has not been properly installed will be seriously
injured and can be killed.
• Even though your vehicle is equipped with an Advanced Airbag
System, make certain that all children, especially 12 years and
younger, always r ide on the back seat properly restrained for their
age and size.
• Always install forward or rear-facing child safety seats on the
rear seat -even with an Advanced Airbag System.
• If you must install a rearward-facing child safety seat on the
front passenger seat because of exceptional circumstances and
the PASSENGER AIR BAG OFF light does not appear and stay on, immediately install the rear-facing child safety seat in a rear

seating position and have the airbag system inspected by your
Audi dealer .
• A tight tether o r other strap on a rearward -facing child
restraint attached to the front pa ssenger seat can put too much
pressure on the weight -sensing mat in the seat and register more
weight than i s actually on the seat . The heavier weight regi stered
can make the system work as though an adult were on the seat
and deploy the Advan ced Airbag when it mu st be suppre ssed
causing serious or even fatal injury to the child .
• If , in exceptional circumstanc es, you must install a forward­
facing child restraint on the front passenger seat, always move
the seat into its rearmost po sition in the seat' s fore and aft adjust­
ment range, as far away from the airbag as possible . The backrest
must be adjusted to an upright position. Make sure that the PASSENGER AIR BAG OFF light comes on and stays on all the time
whenever the ignition is switched on.
& WARNING
• If the PASSENGER AIR BAG OFF light doe s not go out when an
adult is sitting on the front passenger seat after taking the steps
described above, make sure the adult is properly seated and
restrained at one of the rear seating positions.
• Have the airbag system inspected by your Audi dealer before
transporting anyone on the front passenger seat.
[ i ] Tips
If the we ight-sens ing mat in the front passenger seat detects an
em pty seat , the front airbag on the passenge r side will be t urne d off,
and the PASSENGER AIR BAG OFF light will stay on .•

Repair, care and disposal of the airbags
Parts of the airbag system are
insta lled at many different places on
your Audi . Ins tall ing, remov ing, serv icing o r rep airi ng a pa rt in an
area of the vehicle ca n damage a part of a n airbag system and prevent
t ha t sys tem from working prope rly in a coll is io n.
Th ere are some importa nt things you have to know to ma ke sure t hat
the effectiveness of the system will not be impai red and that
dis ca rded compo nents do not cause injury or po llute t he e nvir on­
ment .
& WARNING
Improper care , serv icing and repair procedures can increase the
risk of personal injury and death by preventing an airbag from
deploying when needed or deploying an airbag unexpectedly:
• Never cover, obstruct, or change the steering wheel horn pad or
airbag cover or the instrument panel or modify them in any way .
• Never attach any objects such as cupholders or telephone
mountings to the surfaces covering the airbag units .
• For cleaning the horn pad or instrument panel, use only a soft ,
dry cloth or one moistened with plain water . Solvent s or cleaners
could damage the airbag cover or change the stiffness or strength
of the material so that the airbag cannot deploy and protect prop ­
erly.
• Never repair, adjust, or change any part s of the airbag system .
• All work on the steering wheel, instrument panel , front seats
or electrical sy stem (including the installation of audio equip­
ment, cellular telephones and CB radios, etc. ) must be performed
by a qualified technician who has the training and special equip­ ment necessary .
• For any work on the airbag system, we strongly recommend
that you see your authorized Audi dealer or qualified workshop.
• Never modify the front bumper or parts of the vehicle body . ..,_

Other things that can affect Advanced
Airbag performance
Chang ing the vehicle's suspension system can change the way that
t h e Advan ced Airbag System pe rforms in a cr ash . For e xamp le, usi ng
tire-rim combinations not app roved by Audi, lowering the vehicle,
c hang ing the stiffness o f th e suspension, incl uding the sp rings,
suspension struts, shock absorbers etc. can change the forces that
are meas ured by the a irbag sensors and sent to the ele ct ronic contro l
unit . Some suspension changes can, fo r exam ple, increase the force
levels measured by the senso rs and make the airbag system deploy in
crashes in which i t would not deploy if the changes had no t been
ma de . Other kinds of changes may reduce the force levels meas ured
by the sensors and p revent the airbag from dep loying when it should.
T he sensors in the safety belt b uckle for the drive r and front
p as senge r se at tell the e lectroni c cont rol mo dule if the sa fe ty belt is
latched or not . If the safety belt is being used, t he front a irbag w ill
dep loy a t a s lightly h igher r ate o f vehicle decele ration t han if t he
safety belt is not be ing used . Therefo re, in a par ticular collis io n, it is
possible that an a irba g w ill not dep loy at a seating position where the
safety belt is being used but w ill inflate at the posit ion where the
safety belt is not be ing use d. It is im portant that nothing interfere
w it h t he safety belt bu ckles so that t he sensors can se nd the co rrect
info rmation about safety be lt use to the electronic contro l unit.

& WARNING
Changing the vehicle's susp ension including use of unapproved
tire -rim combination s can change Advan ced Airbag performance
and increase the risk of serious personal injury in a crash .
• Never install suspension component s that do not have the
same performance characteristics as the components originally
installed on your vehicle.
• Ne ver use tire-rim combinations 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 control module and prevent the
Advanced Airbag System from working properly.
• Always make sure that nothing can interfere with the safety

Fig. 18 5 S ide air bag
loca tion in the d river's
seat
T he side airbags are located in t he sides of t he front seat backrests
~ fig. 185 and the rear backrest * facing the doors. They are ide nti ­
fie d by th e word "AIRBAG" .
The side airbag system basically consists of :
• the ele ctron ic cont rol mod ule and extern al side imp act se nsors
• the two side airbags located in t he sides of the front backrests
• two rear side airbags (as an o rde red
o p tion)
• the airbag wa rni ng light in the instr ument cluster .
Th e air bag sys tem is monitore d ele ct ronically to m ake ce rtain that it
is funct io ning properly at all times. Each t ime you turn on the igni­
tion , the airb ag system indica tor light w ill come on fo r a few seconds
(self d iagnostics).
Th e side airbag sy stem sup plements the safety belts and can he lp to
re du ce the risk of inju ry to the dr ive r's, fron t and rear* passenger 's
upper torso on the side of the ve hicle that is struck in a side coll is ion.

is below the reference va lue programmed into the cont rol unit, the
side airba gs w ill no t be triggered, even though t he car may be b ad ly
damaged as a result of the collision. It is not possible to define an
airbag tr iggering range that w ill cover every possible angle of impact,
since the circumstances will vary considerably between one collision
and another . Important factors include, for example, the nature
(hard or soft) of the impacting object, the angle of impact, vehicle
speed, etc.~
page 215, "Important safety instructions on the side
airbag system" .
Aside from the ir normal safety function, safety be lts work to help
keep the d river or front passenger in posit ion in the event of a side
co llision so that the side airbags can provide protection.
The airbag system is
not a substitute for your safety belt. Rather, it is
part of the ove rall occupant restraint system in your veh icle. Always
remember that the side airbag system can only help to protect you if
you a re wearing your safety belt and wearing it p rope rly. This is
another reason why you shou ld always wear your safety belts, not just
because the law requires you to do so~
page 187, "General no tes" .
It is important to remembe r that wh ile the supp lemental s ide airbag
system is designed to reduce the likelihood of se rious injuries, ot her
injuries, fo r examp le, swe lling, bru ising, and minor abras ions can
also be associated with deployed side airbags . Remember too, side
airbags will dep loy only once and only in certai n kinds of accidents -
your safety belts are always there to offer protection.
Vehicle damage, repair costs or even the lack of veh icle damage a re
not necessar ily an ind ication of over-sensitive or failed airbag activa­
t ion . In some collisions, both front a nd side airbags may inflate .
Remember too, that a irbags will deploy only once and only in certa in
kinds of collisions -your safety belts are a lways there to offer protec­
tion in those acc idents in w hich airbags a re not supposed to deploy or
when they have already deployed.
The side airbag system will not deploy :
• when the ignition is turned off
• in side collisions when the acceleration measured by the sensor is
too low •
in front-end collis ions
• in rea r-end collisions
• in rollovers .
In some types of accidents the front a irbags, side curtain airbags and
side airbags may be triggered together.
& WARNING
• Safet y belts and the airbag s ystem will only provide protection
when o ccupants are in the proper seating position ~
page 215.
• If the airbag indicator light comes on when the vehicle i s being
used, have th e system inspe cted immediately by your authoriz ed
Audi dealer. The airbag may not work prope rly when the vehicle
a cceleration in a side collision is high enough to activate the
ai rbag. •
How supplemental side airbags work
Side airbags deploy instantly and can help reduce the risk
of upper torso injuries for occupants who are pro perly
restrained.
