148 Airbag sys tem
Even tho ugh your vehicle is equip ped with an
Advanced Airbag System , make certain that
a ll c hildren, especially those 12 years and
younge r, a lways ride in the back seat properly
restra ined for their age and size. The airbag
on the passenger side makes the front seat a potentially dangerous place for a ch ild to r ide.
The front seat is not the safest place for a
child in a fo rward-facing ch ild safety seat. It
can be a very dangerous place for a n infant or
a child in a rea rward-facing seat.
The Advanced Airbag System i n your veh icle
has been certified to comp ly with the Requ ire­
men ts of Uni ted Sta tes Federa l Mo tor Veh icle
Safety Standard 208 as applicable at the time
your veh icle was manufactured.
The Standard requires the front a irbag on t he
passenger side to be turned off ("sup­
pressed") if a ch ild up to about one year of
age restrained in one of the rear -facing o r for­
ward -facing infant restraints listed i n Federal
Motor Vehicle Safety Standard 208 with which
the Advanced A irbag System in your vehicle
was certified has been installed o n the front
passenger seat . For a listing of the child re ­
strai nts t hat we re used to certify compliance
with the US Safety Standard
r=vpage 169.
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 t ime you turn on the ignition, the
PAS ­
SENGER AIR BA G OFF
light will come on for a
few seconds a nd:
- will stay on if the front passenger seat is not
occupied,
- wi ll stay on if there is a small child or child
restraint on the front passenger seat,
- wi ll go off if the front passenger seat is oc ­
cupied by an adult as registered by the
weight-sensing mat
r=v page 156, Monitor­
ing the Advanced Airbag System .
The PASSENGER AIR BAG OFF light comes on
when the control un it detects a total weight
on the front passenger seat that requ ires the
fro nt 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 hil d but less than the weight o f 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 passeng er side has not
been turned off by the elec troni c con trol unit
and can deploy if the control uni t se nses an
impact that meets the cond itions stored in its
memo ry .
For example, the airbag may deploy if:
- a small ch ild that is heav ier t han a typical 1
year-old ch ild is on the front passenger seat
( r egard less of whethe r the child is i n one of
t he child safety seats listed
r=v page 169), or
- a child who has outgrown ch ild restraints is
on t he front passenge r seat.
If the front passenger airbag is turned off, the
PASSENGER AIR BAG OFF light comes on in
the instr ument cluster and stays on.
The front airbag on the passenger s ide may
not deploy (the PASSENGER AIR BAG OFF
li gh t 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 res t w it h thei r feet on the
vehicle f loor i n front of the sea t is on the front
passenger seat
r=v page 129 , Proper seating
position for the driver.
If t he fron t passenger a irbag dep loys, the
F ede ra l Standard req uires the airbag to meet
t h e "low risk" dep loyment criteria to red uce
t h e risk of injury t hrough interactio n wit h the
airbag. "Low risk" dep loyment occ urs in those
crashes that take place at lower dece lerat ions
as defined in the electronic control unit
r=v page 157, PASSENGER AIR BAG OFF light .
Always remember, a child safety seat or infant
carr ier installed on the front seat may be
struck and knocked out of posit ion by the rap­
idly inflat ing passenger 's airbag in a fronta l
collision . T he a irbag could great ly reduce the
effectiveness of the ch ild restra int and even
seriously injure t he ch ild dur ing inflation .

For this reason, and because the back seat is
the safest place for children - when properly restrained according to their age and size - we
strongly recommend that children always sit in the back seat
Q page 167, Child Safety.
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.
- T he inflating a irbag w ill hit the child
safety seat or infant carrier w ith great
force and w ill smash the ch ild safety sea t
and child against the backrest, cente r
armrest, door or roof .
- Always install rear -facing child safety
seats on the rear seat.
- If you mus t inst all a rearward facing
child safety seat on the front passenger
seat beca use of exceptional circumstan­
ces and the
PASSENGER 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 system inspected by your
authorized Aud i dealer .
- Forward-fac ing ch ild safety seats instal­
led on the front passenger's seat may in­
terfe re with the deployment of the air­
bag and cause se rious personal injury to
the ch ild.
A WARNING
If, in exceptional c irc umstances, you mus t
install a forwa rd-facing child restra int on
the front passenger's seat:
- Alw ays make sure the forw ard -fac ing
sea t has been des igned and certified by
its manufacturer for use on a front seat
with a passenger front and side airbag.
- Never put the forward -facing child re ­
straint up aga inst or very near the instru­
ment pane l.
- Always move the passenger seat into its
rearmost position in the seat's fore and
A irbag system 149
aft ad justment range, as far away from
the airbag as possible before installing
the forward-fac ing ch ild restraint. The
backrest must be adj usted to an upright
position .
- Make sure that the
PASSENGER AIR BAG
OFF
li ght comes on and stays on all the
time wheneve r the ignit ion is switched
on.
A WARNING
T o reduce the risk of ser ious injury, make
su re that the
PASSENGER AIR BAG OFF
light w ill be displayed whenever a child re­
straint is installed on the front passenger
seat and the ignition is switched on.
- If the
PASSENGER AIR BAG OFF light
does not s tay on, per form the checks de ­
scribed
Q page 156, Monitoring the Ad ­
vanced Airbag System.
- Take the chi ld restraint off the front pas­
senger seat and install it properly at one
of the rear seat positions if the
PASSEN ­
GER AIR BAG Off light does not stay on.
- Have the airbag system inspected by
your author ized Audi dealer immed iate­
ly .
-Always carefu lly follow instr uctions from
child restraint manufacturers when in­
stall ing ch ild restra ints .
A WARNING
If, in except iona l circumstances, you must
install a forward or rearward-facing child
restra int on the front passenger's seat :
- Improper instal lation of ch ild restraints
can reduce their effectiveness o r even
prevent them from providing any protec­
tion.
- An improper ly installed ch ild restra int
can interfere with the airbag as it de­
ploys and seriously i njure o r even kill the
child -even with an Advanced Airbag
System.
- Always carefu lly follow the manufact ur­
er 's ins tructions p rov ided with the ch ild
safety seat or carrier . •
•

-Always move the passenger seat into its
rearmost position in the seat's fore and
aft adjustment range, as far away from
the a irbag as poss ible, before insta lling
the forward-facing child restraint. The backrest must be adjusted to an upr ight
posit ion.
- Make sure that the
PASSENGER AIR BAG
OFF
light comes on and stays on all the
t ime w henever the ignition is sw itched
o n.
Advanced Airbag System components
The fron t passenger seat in your vehicle has a
lot of very important parts of the Advanced
Airbag System in it. These parts include the
weight-sens ing mat, sensors, wiring, brack ­
ets, and more. The function of the system in
the front passenger seat is checked by the
e lectronic control u nit when the ignit ion is on .
The control un it mon itors the Advanced Air­
bag System and turns the airbag indicator
l ight on whe n a ma lfunction in t he sys tem
components is de tected. The function of the
airbag indicator light is described in greater
detai l below . Because the front passenger
seat contains important parts of the Ad ­
vanced A irbag System, you m ust 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 Airb ag Sy stem
consists of the following:
- Crash sensors in the front of the veh icle that
measure veh icle acceleration/decele ration
to provide information to the Advanced Air­
bag System about the seve rity of the crash.
- An electronic co ntrol unit, with integrated
c rash se nsors for front and side impacts .
T he cont ro l unit " decides " whethe r to fire
the front airbags based on the inform ation
received from the crash senso rs . The contro l
unit a lso "decides" whether the safety belt
pretensioners should be activated .

A WARNING
To reduce the risk of injury when an airbag
inflates, always wear safety belts properly.
- If you are unrestrained, lean ing forward,
sitting sideways or out of position in any
way, your risk of injury is much higher.
- You w ill also receive serious injuries and
could even be killed if you are up against
the a irbag or too close to it when it in­
fla tes - even with an Advanced Airbag
~page 146.
More important things to know about
front airbags
Fig. 155 Inf lated front a irbags
Safety belts are impo rtant to help keep front
seat occupants in the p roper seated pos ition
so that airbags can unfo ld properly and pro­
v ide supp lemental protection in a fronta l col­
lision.
The front a irbags are designed to provide ad­
d itiona l protection for the chest and face of
the dr iver and the front seat passenge r when:
- safety belts are worn prope rly,
- the seats have been posit ioned so that the
occupant is properly seated as far as possi­
ble from the a irbag,
- and the head restraints have been properly adjusted .
Because airbags i nflate in the blink of an eye
with great force, things you have on your lap
or have placed on the seat could become dan ­
ge ro us projectiles, and be pushed into you if
the airbag inflates.
When an a irbag deploys, fine dust is released.
This is normal and is not caused by a fire in
A irba g sy stem 155
the vehicle . This dust is made up mostly of a
powder used to lubricate the airbags as they
deploy. It could irr itate skin.
It is important to remembe r that wh ile the
supplementa l airbag system is designed to re­
duce the like lihood of serious injuries, other
injur ies, for example swelling, br uis ing and
minor abrasions, can also happen when air­
bags inflate. Airbags do not protect the arms
or the lower parts of the body . Front a irbags
o nly supplement the three point safe ty belts
in some fronta l co llisions in which the vehicle
decelera tion is h igh enough to deploy the air­
bags.
Front airbags will not deploy :
- if the ignition is sw itched off when a crash
occu rs,
- in side co llisions,
- in rear-end collisions,
- in rollovers,
-when the crash deceleration measured by the airbag system is less than the minimum
threshold needed for airbag dep loyment as
reg istered by the electronic contro l unit .
The front pa ssenger ai rbag will also not
deploy:
- 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 ind icates that the front airbag on the
passe nger side has to be turned off by the
electronic control unit (the
PASSENGER AIR
BA G OFF
light comes on and stays o n).
A WARNING
-S itting in the wrong pos ition can in crease
the r is k of se rious inj ury i n crashes.
- To reduce the risk of injury when the air­
bags inflate, the drive r and passenge rs
m ust always s it in an upr igh t positi on,
m ust not lean against or pla ce any part
of their body too close to the area whe re
the airbags a re located. .,.

whenever the ignition is on. Each time yo u
turn on the ignition, the
fl airbag monitoring
indicator light w ill come on for a few seconds
(self diagnostics) .
The system mu st be in spected wh en the
II indicat or light:
- does not come on w hen the ignit ion is
switched on,
- does not go out a few seconds after you
have switched on the ignition, or
- comes on whi le driving .
I f an a irbag system malf unct ion is de tected,
the ind icator light will firs t start flashing to
