Child restraints on the front seat - some
important things to know
~ Be sure to read the important informat ion
and head the WARNINGS for important de­
ta ils about ch ildren and Advanced Airbags
c::>page 133.
Even though your vehicle is equ ipped with an
Advanced Airbag System, make certain that
a ll c hildren, especially those 12 years and
younger, a lways ride in the back sea t properly
restrained for their age and size . The airbag
on the passenger side makes the front seat a
potentially dangerous place for a chi ld to ride.
The front seat is not the safest place for a
child in a forward-facing child safety seat. It
can be a very dangerous place for an infant or
a child in a rea rward-facing seat .
The Advanced Airbag System in your veh icle
has been certified to comply with the Requ ire­
ments of United States Federa l Motor Veh icle
Safety Standard 208 as applicable at the time
your veh icle was manufactured .
The Standard requires the front a irbag on the
passenger side to be turned off ("sup ­
pressed") if a ch ild up to about one yea r of
age restra ined in one of the rear-facing or fo r­
ward-facing infan t restra ints listed in Federal
M otor Vehicle Safety Standard 208 w ith w hic h
the Advanced A irbag System in your vehicle
was certified has been installed on the front
passenger seat. Fo r a listing of the child re­
straints that were used to certify compliance
with the US Safety Standard
c::> page 135.
The PASSENGER AIR BAG OFF light in the in­
strument panel te lls you when the front Ad ­
vanced A irbag on the passenger side has been
turned off by the e lectronic control unit.
Each time yo u turn on the ignition, the
PAS­
SENGER AIR BAG OFF
li ght wi ll come on for a
few seconds and:
- will stay on if the front passenger seat is not
occupied, -
w ill s tay on i f there is a small ch ild or child
restraint on the front passenger seat,
- will go off i f the front passenger sea t is oc­
cupied by an adult as registered by the
weight-sensing mat
c::> page 123, Monitor­
ing the Advanced Airbag System.
T he PAS SENGER AIR BAG OFF light comes on
whe n the control unit detects a tota l weight
o n the front passenger seat that req uires the
front airbag to be turned off .
If the total weight on the front passenge r
seat is more than that of a typica l 1 year -old
c h ild b ut less than the weight of a small
adult, the front airbag on the passenger side
can deploy (the
PASSENGER AIR BAG OFF
li ght does not come on). If the PASSENGER
AIR BAG OFF
light does not come on, the
front a irbag on the passenger side has not
been turned off by the elect ronic control unit
and can deploy if the cont rol uni t senses an
impact that meets the cond itions s tored i n its
memo ry .
For exampl e, th e ai rbag may deploy if;
- a small ch ild that is heav ier than a typical 1
year-old ch ild is on the front passenger seat
( r egardless of whether the child is in one of
the ch ild safety seats listed
c::> page 135) , or
- a child who has outgrown chi ld restraints is
on t he front passenger seat .
If the front passenger airbag is turned off, the
PASSENGER AIR BAG OFF light comes on in
the instrument cluster a nd stays on .
The front airbag on the passenger side may
not deploy (the PASSENGER AIR BAG OFF
light does not illum inate and stay lit) even if a
small adult o r teenager, or a passenger who is
not sitt ing up rig ht w ith their back against a
non- recl ined ba ck rest w it h their feet on the
vehicle f loor i n front o f the sea t is on t he front
passenge r seat
c::> page 95, Proper seating po ­
sition for the driver.
If the front passenger airbag dep loys, the
F edera l Standard req uires the airbag to meet
the "low risk" dep loyment criteria to red uce
t h e risk of injury t hro ugh interactio n with the ..,.

airbag. "Low risk" deployment occurs in those
crashes that take place at lower decelerations
as defined in the electronic control unit
c:> page 123, PASSENGER AIR BAG OFF light.
Always remember, a child safety seat or infant
carrier installed on the front seat may be
struck and knocked out of pos ition by the rap­
id ly inflating passenger's airbag in a frontal
collision. The airbag could greatly reduce the
effectiveness of the child restraint and even
seriously injure the child during inflat ion .
For this reason, and because the back seat is
the safest place for children -when properly
restrained accord ing to their age and size -we
strongly recommend that children always sit
i n the back seat
c:> page 133, Child Safety.
.&_ WARNING
-
A child in a rearward -facing child sa fety
seat insta lled on the front passenger seat
wi ll be seriously injured and can be ki lled if
the front airbag inflates -even with an Ad ­
vanced Airbag System .
- The inflating a irbag w ill hit the child
safety seat or infant carrier with great
force and will smash the child safety seat
and child against the backrest, center
armrest, door or roof.
- Always install rear -facing child safety
seats on the rear seat.
- If you must install a rearward facing
child safety seat on the front passenger
seat because of exceptional circumstan­
ces and the
PAS SENGER AIR BAG OFF
light does not come on and stay on, im­
med iately install the rear-facing child
safety seat in a rear seating posit ion and
have the a irbag sys tem inspected by you r
authorized Aud i dealer.
- Forward-fac ing ch ild safety seats instal­
led on the fron t passenger's seat may in­
terfere with the deployment of the air­
bag and cause serious personal injury to
the chi ld .

.&_ WARNING
If, in exceptiona 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 fo r 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 ve ry near the instru­
ment panel.
- Always move the passenge r seat into its
rea rmost pos ition in the seat's fore a nd
aft ad justment range, as fa r away from
the airbag as possible before installing
the forward -fac ing chi ld restra int . The
backrest must be adj usted to an up right
position.
- Make sure that the
PASSENGER AIR BAG
OFF
li ght comes on and stays on all the
time whenever the ignition is switched
on.
A WARNING
To reduce the risk of ser ious injury, make
sure that the
PASSENGER AIR BAG OFF
light w ill be displayed whenever a child re­
straint is installed on the front passenge r
seat and the ignition is sw itched on .
- If the
PASSENGER AIR BAG OFF light
does not stay on, perform the checks de­
scribed
c:> page 123, Monitoring the Ad­
vanced Airbag System.
- Ta ke the chi ld restraint off the front pas­
senger sea t and install it prope rly at one
of the rear sea t positions if the
PASSEN­
GER AIR BAG OFF
light does not stay on.
- Have the airbag system in spe cted by
your author ized Audi dealer immed iate­
ly.
- Always carefully follow instr uctions from
child restraint manufacturers when in­
stalling child restraints.

118 Airbag sys te m
restrained in one of the rear -facing or for­
ward -facing infant restraints (listed in Federal
Motor Vehicle Safety Standard 208 with which
the Advanced Airbag System in your vehicle
was certified), the front airbag on the passen­
ger side may or may not dep loy .
The
PASSENGER AIR BAG OFF light comes on
when the electronic control unit detects a to­
tal weight on the front passenger seat that re­
quires the front airbag to be turned off . If the
P A SSENGER AIR BAG OFF light does not
come on, the front airbag on the passenger
side has not been turned off by the control
un it and can deploy if the contro l unit senses
an impact that meets the conditions stored in
its memory .
I f the total we ight on the front passenger
seat is more than that of a typical
1 year-o ld,
but less than the weight of a small adu lt, the
front airbag on the passenger side may deploy
(the
PAS SENGER AIR BAG OFF light does not
come on).
F o r e xample , th e ai rbag m ay depl oy if:
-a small child that is heavier than a typical 1
year-o ld child is on the front passenger seat
(regardless of whether the ch ild is in one of
the chi ld safety seats listed
¢ page 135),
-a ch ild who has o utgrown child rest raints is
on the front passenger seat.
If the front passenger airbag is turned off, the
PA SSENGER AIR BAG OFF light in the center
of the instrument pa nel w il l come on and stay
on.
The front a irbag on the passenger side may
not deploy (the PAS SENGER AIR BAG OFF
light does not ill uminate and stay lit) if:
- a small adult or teenager is on the front pas ­
senger seat
- a passenger who is not sitt ing upright with
their back against a non-reclined backrest
with their feet on the veh icle floo r in front
of the seat is on the fro nt passenger seat.
If the front passenger airbag deploys, the Federal Standard requires the airbag to meet
the "low risk" deployment cr iteria to help re- duce the risk o
f injury through interaction
with the airbag . "Low risk" deployment occurs
in those crashes that take place at lower de­
ce lerat ions as defined in the electronic control
unit.¢
page 123
Alw ays remembe r: Even though your vehicle
is equ ipped w ith Advanced A irbags, the safest
place for ch ildren is properly restrained on the
back seat . Please be sure to read the impor­
tant information in the sections that follow and be su re to heed all of the WARNINGS.
A WARNING ,.__
To reduce the risk of in jury when an a irbag
i nflates, always wear safety be lts p roperly.
- If you are unrestra ined, leaning forward,
sitt ing s ideways or out of pos ition in any
way, your risk of injury is m uch h igher.
- You will a lso receive serious injuries and
could even be killed if you a re up aga inst
the airbag o r too close to it when it in­
f lates - even with an Advanced A irbag
¢ page 112.
A WARNING
= -
A child in a rearward -facing chi ld safety
seat installed on the front passenger seat
will be serious ly injured and can be killed if
the front airbag inflates -even with an Ad­
vanced A irbag System.
-Altho ugh the Advanced Airbag System in
your veh icle is designed to turn off the
front airbag when a rearward-facing
child restraint has been installed on the
front passenge r seat, nobody can abso­
lutely g uarantee that dep loyment is im­
possible in all con ceivable situations that
may happen dur ing the usefu l life of your
vehicle .
- The infla ting airbag will h it the c hild
safety seat or infant carrier wi th great
force and will smash the child safety seat and child against the backrest, center
armrest, door, or roof.
- Always install rearward-facing chi ld re­
straints in the back seat .

Advanced Airbag System components
The fron t passenger seat in your vehi cle has a
l ot of very important par ts of the Advanced
Airbag System in it. These parts include t he
weight -sens ing mat, sensors, wiring, brack­
ets, and mo re. 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 tur ns the a irbag indicator
light on when a ma lfu nction in t he system
components is de tected. The func tion of the
a ir bag ind icator light is described in greater
detai l below . Because t he front passenge r
Airbag sys tem 119
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 do ing its job in
a crash.
The front Advanced Air bag System
consists of the following:
- Cras h sensors in the front of the vehicle that
measure vehicle acceleration/deceleration
to prov ide info rmat ion to the Adva nced Ai r­
bag System about the sev erity of the crash .
- An elect ronic control unit, with integrated
crash sensors fo r front and s ide impacts.
The control u nit "decides" whether to fi re
t he front a irbags based on t he informat io n
received from t he crash sensors. The con trol
unit also "decides" whe ther the sa fety belt
pretensioners sho uld be activated.
- An Adv anced A irbag w it h gas gene ra tor and
cont ro l valve fo r the d river inside the steer ­
ing wheel h ub.
- An Advance d Airbag w ith gas generator and
contro l valve inside the inst rument pane l for
the front passenger .
- A wei ght -sensing mat unde r the upho ls tery
padding of the front passenge r seat cushion
that measures the total weight on the seat .
The informat ion reg istered is sent continu­
ously to the electronic control unit to regu­
late deployment of the front Advanced Air­
bag on t he passenger side.
- An airbag monitoring system and ind icator
light in the instr ument cluster¢
page 123.
-A sensor in each front seat registers the dis­
tance between the respective seat and the
steer ing whee l or inst rument panel. The i n­
formation register ed is sent cont inuo usly to
t he ele ct ron ic cont ro l unit to regula te de­
ployment o f th e front Adva nced A irbags .

& 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 wi ll pre­
vent the Advanced Airbag System from
functioning properly.
- Repairs to the front passenger seat must
be performed by q ualified and properly
trained workshop personnel.
- Never
remove the front passenger or
dr iver seat from the veh icle.
- 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-sens ing mat and send the
wrong information to the airbag control
unit.
- Never store items under the front pas­ senger seat. Parts of the Advanced Ai r­
bag System under the passenge r seat
cou ld be damaged, prevent ing them and
t h e a irbag sys tem from wo rking proper­
ly .
-
- Never p lace seat covers or rep lacement
upho lstery that have not been specifica l­
ly approved by Audi on the front seats.
- Seat
covers can prevent the Advanced
Airbag System from recognizing chi ld 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. T he additional padding w ill prevent
the we igh t-sensing mat in the sea t from
accurately regis tering the child rest rain t
or pe rson on the seat and prevent the
Advanced Airbag System from function­ ing p roperly.
- If you m ust use a child restraint on the
front passenge r seat and the child re­
straint manufacture r's instructions re­
quire the use of a towel, foam cushion or
someth ing e lse to properly pos ition the
child restraint, make certain that the
PASSENGER AIR BAG OFF light comes
on and stays on whenever the ch ild re­
s traint is i nstalled on the front passen­
ge r seat.
- If the PASSENGER AIR BAG OFF light
does not come on and st ay on, immed i­
ately install child rest raint in a rear seat­
ing position and have the ai rbag system
inspected by your authorized Audi dealer.
How the Advanced Airbag System
components work together
The front Advanced Airbag System and the
s ide a irbags supp lement the protect ion of­
fered by the front three-point safety belts
with pretensioners and load limiters a nd the
adjus table head rest rain ts to help reduce the
r isk of in jury in a wide range of accident and
c rash situations . Be s ure to read the impor ­
tant information about safety and heed the
WARNINGS in this chapter .
Deployment o f the Adv a need A irbag System
and the activation of the safety belt preten­
sioners depend on the deceleration measured
1111-

122 Airbag sys te m
Th e front p assenger airbag will als o not
d eploy:
- when the front passenger seat is not occu­
pied,
- when the weight on the front passenger
seat as sensed by the Advanced Airbag Sys­
tem indicates that the front airbag on the passenger side has to be turned off by the
electronic control unit (the
PA SSE NGER AIR
BA G OFF
light comes on and stays on) .
A WARNING
Sitting in the wrong position can increase
the risk of serious inju ry in crashes.
- To reduce the r isk of injury when the air­
bags inflate, the driver and passengers
must always sit in an upright position,
must not lean against o r place any part
of their body too close to the area where
the airbags are located .
- Occ upants who a re unbelted, out of posi­
tion or too close to the airbag can be se ­
riously injured by an airbag as it unfolds
with great force in the blink of an eye
9page 114.
A 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 inflates -even with an Ad­
vanced Airbag System.
- The inflating a irbag will hit the child
safety seat or infant carrier with great
force and w ill smash the ch ild safety seat
and child against the backrest, cente r
armrest, door or roof.
- Always install rear-facing child safety
seats on the rear seat.
- If you must install a rearward facing
child safety seat on the front passenger
sea t because of exceptional circ umstan­
ces and the
PA SSENGER AIR BAG OFF
light does not come on and stay on, im­
mediately install the rear-facing child
safety seat in a rear seating position and have the airbag system inspected by your
author ized Audi dealer.
A WARNING
-
Objects between you and the airbag will
i ncrease the r isk of injury in a crash by in­
terfering with the way the airbag unfolds
or by be ing pushed into you as the airbag
i nflates.
- Never hold things in your hands or on your lap when the veh icle is in use.
- Never transport items on or in the area
of the front passenger seat. Objects
could move into the a rea of the front air­
bags du ring bra king or other sudden ma­
neuver and become dangerous p rojec­
tiles that can cause ser ious personal in­
jury if the airbags inf late.
- Never p lace or attach accessories or oth­
er objects (such as cupholders, tele ­
phone brackets, large, heavy or bulky ob­
jects) on the doors, over or near the area
marked "AIRBAG" on the steering whee l,
instr ument panel, seat backrests or be ·
tween those areas and yourself. These
objects could cause in ju ry in a crash, es­
pecially when the airbags inflate.
- 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 du ring bra king or in a
sudden maneuver. Objects near the air­
bags can become projectiles and cause inj ury, par tic 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 i ng cond itions.
- To reduce the risk of breath ing problems,
those with asthma or other respiratory conditions shou ld get fresh air right
away by getting o ut of the veh icle or
open ing windows or doors .

-If y ou are in a collis ion in w hich a irbags
deploy, wash yo ur hands and face w ith
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
A WARNING
An airbag system that is not functioning properly cannot provide supplemental pro­
tection in a frontal crash .
- If the airbag indicator l ight
c> page 16
comes when the vehicle is be ing used,
have the system inspected immediately
by you r autho rized Aud i dea ler. It is pos­
sible that the a irbag will inflate when it
is not supposed to, or w ill not inflate
when it sho uld .
A WARNING
If the front airbag inflates , a ch ild without
a child restraint, in a rearward-facing child
safety seat or in a forward-facing chi ld re­
straint that has not been properly insta lled
w ill be seriously injured and can be k illed.
- Even though your veh icle is equipped
with an Advanced Airbag System, make certain that a ll children, especially 12
years and younge r, always ride o n the
back seat properly restrained fo r their
age and si ze.
- Always install forward or rea r-facing
child safety seats on the rear seat - even
with an Advance d Airbag System. A

- If you must install a rearward-facing
child safety seat on the front passenger
seat because of exceptional circumstan­
ces and the
PA SS ENG ER AIR BAG OFF
light does not appear and stay on, imme­
diate ly install the rear-facing child safety
seat in a rea r seat ing pos ition and have
the airbag system inspe cted by your au­
thorized A udi dealer.
- A t ight tether or other strap on a rea r­
ward-facing child restraint attached to
the front passenger seat can p ut too
m uch pressure on the weight-sensing
mat in the seat and registe r more weight
than is actually on the seat. The heavier
weight registered can make the system
work as though an adult were on the seat
and deploy the Advanced Airbag when it
must be suppressed causing ser ious or
even fata l injury to the ch ild.
- If, in exceptiona l circumstances, you
must install a forward-fac ing ch ild re­
straint on the front passenger seat, al­
ways 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 adjust­
ed to an upright pos ition. Make sure that
the
PASSENGER AIR BAG OFF light
comes on and stays on all the time when­
ever the ignit ion 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 sea t after taking
the steps described above, make su re the
adu lt is properly seated and restra ined at
one o f the rear seat ing pos itions.
- Have the airbag system inspected by
your author ized Audi dealer befo re trans­
porting anyone on the front passenger
seat.

Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced A irbag 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 a irbag
sensors and sent to the electronic co ntrol
u ni t. Some suspension changes can, for exam­
p le, increase the fo rce levels measured by the
se nsors and make the airbag system deploy in
crashes in w hich it would not dep loy i f 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 s uspension includ­
ing use of unapproved tire-rim combina­
tions can change Advanced Airbag pe r­
formance and increase the risk of ser ious
personal in jury in a crash.
- Never install suspe nsion components
t ha t do not have the same per fo rman ce
c h arac ter istics as the componen ts or igi­
nally insta lled on your vehicle .
- Never use ti re -r im combi nat ions tha t
h ave not been approved by A udi.
A WARNING
-
Items s tored 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 tro l modu le and prevent the Advanced A ir­
bag System from work ing properly.

Side airbags
Description of side airbags
The airbag system can provide supplemental
protection to properly restrained occupants .
Fig . 1 21 Side a irbag locat ion in the driver's seat
The side airbags are located in the sides of the
front seat backrests<=)
fig. 121 facing the
doo rs . They are identified by the word "AIR­
BAG".
The side airbag sy stem bas icall y consi st s of :
- t he ele ctron ic cont rol modu le and external
side impact sensors
- the two a irbags located in the s ides of the
front backrests
- t he airbag warning ligh t in the instrument
cluste r.
The airbag system is monitored electronically
to make ce rtain that it is f unctioning properly
at all times. Each time you turn on the ig ni­
tion, the airbag syst em ind icator light will
come on for a few seconds (se lf diagnostics).
The side airbag system supplements the safe­
ty belts and can help to red uce the risk of in­
jury to the driver's and front passenger's up­ per to rso on the s ide of the vehicle that is
str uck in a s ide collis ion. The ai rbag deploys
on ly in side impac ts and only when the vehicle
acce le ration reg istered by the cont ro l unit is
high enough. If this rate is be low the refer­
ence value programmed into the control unit,
the side airbags will not be triggered, even
