Child restraints on the front seat - some
important things to know
• Be sure to read the important information
and heed the WARNINGS for important de
ta ils about ch ildren and Advanced Airbags
i=> page 203.
Even though your vehicle is equipped with an
Advanced Airbag System, make certain that
all children, especially those 12 years and
younger, 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 child to r ide .
The front seat is not the safest place fo r a
chi ld in a fo rward-facing chi ld safety seat. It
can be a very dangerous place for a n infan t or
a child in a rearward -facing seat.
The Advanced Airbag System i n your veh icle
has been certified to comply with the require
men ts of United States Federa l Mo to r Veh icle
Safety Standard 208 as applicable at the time
your ve hicle was manufact ured.
The Standa rd requires the fron t air bag on t he
passenger side to be turned off ("sup
p ressed") if a ch ild up to about one yea r of
age 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 A irbag System in your vehicle
was certified has been installed on the front passenger seat . For a listing of the child re
straints that we re used to certify compliance
with the US Safety Sta ndard

The PASSENGER AIR BAG OFF light in the in
strument panel tells you when the front Ad
vanced A irbag on the passenger side has been
turned off by t he e lectronic control unit.
Each t ime you tur n on the ignition, the
PAS
SENGER AIR BAG OFF
li ght will come on for a
few seconds a nd:
- will stay on if the front passenger seat is not
occupied
- will stay on if there is a small child or child
restraint on the front passenger seat -
w ill go off i f the front passenger seat is oc
cupied by an adult as registere d by the
weight -sensing mat
r::!) page 193, Monitor
ing the Advanced Airbag System.
T he PASSENGER AIR BAG OFF light comes on
when the control unit detects a tota l weight
on the front passenger seat that req uires the
front a irbag 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 hi ld 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 con trol unit
and can deploy if the control uni t se nses an
impact that meets the cond itions stored in its
memory .
For exampl e, the airbag may deploy if:
- a small ch ild that is heav ie r th an a typical 1
year-old ch ild is on the front passenger seat
( r egard less of whethe r the child is in one of
the child safety seats listed
r::!) page 205), or
- a child who has outgrown ch ild 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 and stays on.
The front airbag on the passenger side may
not deploy (the PASSENGER AIR BAG OFF
li ght does not illum inate and stay lit) even if a
small ad ult o r teenager, or a passenger who is
not sitt ing up rig ht w ith their back against a
non- re cli ned ba ck res t w it h thei r feet on the
vehicle floor in front of the sea t is on the front
passenge r seat

If t he fron t passenger a irbag dep loys, the
F ede ra l St andard req uires the airbag to meet
the "low risk" dep loyment criteria to red uce
the risk of injury t hro ugh interactio n wit h the
airbag. "Low risk" dep loyment occ urs in those

Always remember, a chi ld safety seat or infant
carrier installed on the front seat may be
struck and knocked out of position by the rap
id ly inflating passenger's airbag in a frontal
coll is ion . The airbag cou ld greatly reduce the
effectiveness of the child restraint and even
seriously injure the child during inflat ion.
F or this reason, and because the back seat is
the safest p lace for children -when properly
restra ined accord ing to their age and si ze - we
strongly recommend that children always sit in the back seat¢
page 203, Child Safety.
A WARNING
A child in a rearward-facing child safety
seat insta lled on the front passenger seat

If the tota l weight 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
PASSENGER AIR BAG OFF light does not
come on).
For e xample , the airbag m ay deploy 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 child is in one of
the chi ld safety seats listed
¢ page 205),
-a chi ld who has outgrown child restraints is
on the front passenger seat.
If the front passenger airbag is turned off, the
PASSENGER AIR BAG OFF light in the center
of the instrument pane l w ill come on and stay
on.
The front airb ag on the passenger side may
not deploy (the PASSENGER AIR BAG OFF
light does not ill uminate and stay lit) if:
- a small adu lt o r teenager is o n the front pas
senger se at
- a passenger who is not sitt ing upr ight w it h
their back against a non-reclined backrest
with their feet on the veh icle floo r in front
of the seat is on the front passenge r seat .
I f the front passenge r airbag deploys, the
F ederal Standa rd requires the airbag to meet
the " low ris k'' deployment criter ia to help re
d uce the risk of inj ury through interaction
with the airbag. "Low risk" deployment occurs
in those crashes that take place at lower de
celerations as defined in the electronic control un it.

Advanced Airbag System components
The front passenger seat in your vehicle has a
l ot 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 un it when the ignit ion is on .
The control un it mon itors the Advanced Air
bag Sys tem and turn s the a irbag i ndica tor
light on when a ma lfunction in t he system
components is detected . The function of the
airbag indicator light is described in greater
deta il below. Because the front passenger
seat contains important parts of the Ad
va nced A irbag System, you must take care to
prevent it from being damaged . Damage to
the seat may p revent the Advanced A irbag for
the front passenger seat from doing its job in
a crash .
The front Advanced Airb ag System
consists of the following:
- Crash senso rs in the front of the veh icle that
measu re ve hicle accelera tion/decele ra ti on
to provide info rm ation to the Advanced Air
bag System abo ut the severity of the crash.
A irbag system 189
-An elect ron ic cont ro l unit, with integrated
crash sensors for front and side impacts .
The control un it "decides" whether to f ire

- 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 info rmation to the airbag control
unit.
- Never store items under the front pas·

- Seat covers can prevent the Advanced Airbag System from recognizing child re
straints or occupants on the front pas
senger seat and prevent the side airbag
in the seat backrest from deploy ing prop
erly.
- Never use cush ions, pillows, blankets or
similar items on the front passenger
seat. The add itiona l padd ing will prevent
the weight-sensing mat in the seat from

something 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·
straint is installed on the front passen
ger seat.
- If the PASSENGER AIR BAG OFF light
does not come on and stay on, immed i
ately insta ll child restrain t in a rear seat

inspected by your authorized Audi dealer.
How the Advanced Airbag System
components work together
The front Advanced Airbag System and the
s ide airbags supplement the protection of
fered by the front three-point safety belts
with pretensioners and load limiters and the
adjustable head restraints to help reduce the
risk of inju ry in a wide range of accident and
crash situations. Be s ure to read the impor
tant information about safety and heed the
WARNINGS in this chapter.
Deployment of the Adv a need A irbag System
and the activation of the safety belt preten
sioners depend on the deceleration measured
by the crash sensors and registered by the
electron ic control unit. Crash severity depends
on speed and deceleration as well as the mass
and stiffness of the vehicle or object involved
in the crash .
When the electronic control unit registers a low severity crash and the safety belt is being
used, the airbag will not deploy. If the safety
belt is not being used, the first stage deploys,
followed by the second stage after a much lat· er t ime in the crash sequence.
If the electron ic control unit registers a crash
of medium severity, the first stage of the air ·
bag deploys followed by the second stage at a
much later time in the crash sequence· re·
gard less of whether the safety belt is being
u sed o r not . In higher sever ity crashes as reg
iste red by the electronic control unit, both the ..,.

On the passenger side, regard less of safety
be lt use, the airbag will be turned off if the
weight on the passenger seat is less than the
amo unt programmed in the electronic control
un it. The front airbag on the passenger side
w ill also be turned off if one of the child safe
ty seats that has been certified under Federal
Motor Vehicle Safety Standard 208 has been
recog nized on the seat . The

_&. WARNING
To reduce the risk of injury when an airbag

- If you are unrestrained, lean ing forward,
sitting sideways or out of position in any
way, yo ur risk of inj ury is much higher.
- You w ill also receive serio us injuries and

More important things to know about
front airbags
F ig. 210 Inflated front airbags
Safety belts are important to help keep front
seat occupants in the proper seated pos ition
so that airbags can unfo ld properly and pro
vide supplemental protection in a fronta l col
l ision.
A irba g sy stem 191
The front airbags are designed to provide ad
ditional protection for the chest and face of
the driver and the front seat passenger when:
- safety belts are worn properly
- t he seats have bee n positioned so that the
occ upant is properly seated as far as poss i
b le from the airbag
- and the head restraints have been properly
adj usted
Because airbags inflate in the blink of an eye
with great force, t hings you have on your lap
or have placed on the seat co uld become dan
gerous projecti les, and be p ushed in to you if
the a irbag inf lates.
When an airbag deploys, fine dust is re leased.
T his is no rma l and is not caused by a fi re in
the vehi cle. This dust is made up mos tly of a
powder used to lub ricate the airbags as they
deploy. It could irritate skin.
It is important to remembe r that wh ile the
s u pplementa l airbag system is designed to re
duce the like lihood o f serious injuries, other
injuries, for example swelling, bruising and
minor abrasions, can a lso happen when air
bags inflate . A irbags do not protect the arms
or the lower parts of the body. Front airbags
supplement the th ree-point safety belts only
i n some frontal co llisions in which the vehicle
deceleration is high enough to deploy the air
bags.
Front a irbags will not deploy :
-if the ignition is sw itched off when a crash
occurs
- in side collisions
- in rear-end co llisions
- in rollovers
- when the crash dece leration meas ured by
the air bag system is less than the minimum
threshold needed for airbag deployment as
reg istered by the electronic cont ro l unit
The front passenger airbag also will not
deploy:
- when the front passenger seat is not occu-
pied ..,.
192 Airbag system
- when the weight on the front passenger
seat as sensed by th e Advanced Airbag Sys
tem indicates that the front airbag on the
passenger side has to be turned off by the
electronic control unit (the
PASSENGER AIR
BAG OFF
light comes on and stays on)
A WARNING
Sitting in the wrong position can increase
the risk of serious injury in crashes.
- To reduce the risk of injury when the air
bags inflate, the driver and passengers
must always sit in an upright position,
must not lean against or place any part
of their body too close to the area where
the airbags are located.
- Occupants who are 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
¢page 184.
A WARNING -
A child in a rearward-facing child safety
seat installed on the front passenger seat
will be seriously injured and can be killed if
the front airbag inflates -even with an Ad
vanced Airbag System.
- 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, 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
PASSENGER 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
authorized Audi dealer.
A WARNING
Objects between you and the airbag will
increase the risk of injury in a crash by in
terfering with the way the airbag unfolds
or by being pushed into you as the airbag inflates .
- Never hold things in your hands or on
your lap when the vehicle is in use.
- Never transport items on or in the area
of the front passenger seat. Objects
could move into the area of the front air
bags during braking or other sudden ma
neuvers and become dangerous projec
tiles that can cause serious personal in
jury if the airbags inflate.
- Never place 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 wheel,
instrument panel, seat backrests or be
tween those areas and yourself . These
objects could cause injury 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 side airbag or
the front airbag during braking or in a
sudden maneuver. Objects near the air
bags can become projectiles and cause
injury, particularly when the seat is re
clined.
- Never tilt the front passenger seat back
rest forward when the vehicle is moving.
An inflating airbag will force the back
rest backward and can injure rear seat oc
cupants.
A WARNING
The fine dust created when airbags deploy
can cause breathing problems for people
with a history of asthma or other breath ing conditions.
