Child restraints on the front seat - some
important things to know
-Be sure to read the important information and head the
WARNINGS for important details about ch ildren and
Advanced Airbags~
page 234.
Even though your vehic le is equipped with an Advanced Airbag
System, make certain that a ll children, especia lly those 12 years and
younger , always ride in the back seat proper ly restrained for their
age and size . The airbag on the passenger side makes the front seat
a potentia lly dangerous place for a child to ride. The front seat is not
the safest place for a chi ld in a forward -facing child safety seat. It
can be a very dangerous place for an infant or a child in a rearward ­
facing seat.
The Advanced Ai rbag System in your vehicle has been certified to
comply with the Requirements of United States Federal Motor
Vehicle Safety Standard 208 as applicable at the time your vehicle
was manufactured.
The Standard requires the front airbag on the passenger side to be
turned off ("suppressed") if a chi ld up to about one year of age
restrained in one of the rear-facing or forward-facing infant res traints listed in Federa l Motor Vehicle Safety Standard 208 with
which the Advanced Airbag System in your vehicle was cert ified has
been insta lled on the front passenger seat. For a listing of the child
restraints that were used to certify compliance with the US Safety
Standard =>
page 236.
The PASS ENGER AIR B AG OFF light in the instrument panel tells you
when the front Advanced Airbag on the passenger side has been
t urned off by the electronic control unit.
Each time you turn on the ignition , the
PASSEN GER AIR BA G OFF
light will come on for a few seconds and:
• 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,
• will go off if the front passenger seat is occupied by an adult as
registered by the weight-sensing mat=>
page 223, "Monitoring the
Advanced Airbag System" .
The
P AS SENGER AIR BAG OFF light comes on when the control unit
detects a tota l weight on the front passenger seat that requires the
front airbag to be turned off.
If the total weight on the front passenger seat is more than that of
a typica l 1 year -old child but less than the weight of a small adult,
the front airbag on the passenger side can deploy (the
PA SSE NGER
A IR BA G OFF
light does not come on). If the P ASSE NGER AIR B AG
O FF
light does not come on, the front airbag on the passenger s ide
has not been turned off by the electronic control unit and can
deploy if the control unit senses an impact that meets the condi ­
tions stored in its memory.
F o r e xample , th e a ir b ag m ay dep loy if:
• a small ch ild 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 child safety seats listed
=> page 236), or
• a child who has outgrown chi ld restraints is on the front
passenger seat.
If the front passenger airbag is turned off, the
PASSEN GER AIR BA G
OFF
light comes on in the instrument cluster and stays on.
The fron t airbag on the passenger side may
not deploy (the
PA SS ENGER AIR BA G OFF light does not illuminate and stay lit) even
if a small adult or teenager, or a passenger who is no t sitting upright
with their back against a non -reclined backrest with their feet on the
vehic le floor in front of the seat is on the front passenger seat
=> page 194, "Proper seating position for the driver".
If the front passenger airbag deploys, the Federal Standard requires
the airbag to meet the "low risk" deployment criteria to reduce the risk of injury through interact ion with the airbag. "Low risk" d eploy­
ment occu rs in those crashes that take place at lower decelerations .,.

Airbag system -----------------=~-rm-I
as defined in the electronic control unit~ page 224, "PASSENGER

A lways remember, a chi ld safety seat or infant carrier insta lled on
the front seat may be struck and knocked out of position by the
rap id ly i nfl ating pass eng er's ai rbag in a frontal co llision . The airba g
co uld greatly reduce the effectiveness of the chi ld restraint and
even s erio usly in jure the chi ld du ring infl ation.
F or this reason, and because the bac k seat is the safest place for

& 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 Advanced Airbag System.
• The inflating ai rbag will hit the child safety seat o r infant
carrier with great force and will smash the child safety seat and
child against the ba ckrest , center arm rest , 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 pa ssenger seat because of exceptional circumstances and

• Repairs to the front passenger seat must be performed by qual­
ified and properly trained workshop personnel.
• Never remove the front passenger or driver seat from the
vehicle.
• 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 passenger seat . Parts of the
Advanced Airbag System under the passenger seat could be damaged , preventing them and the airbag system from working
properly.
• Never place seat covers or replacement upholstery that have
not been specifically approved by Audi on the front seats.
& WARNING (continued)
• Seat covers can prevent the Advanced Airbag System from
recognizing child restraints or occupants on the front passenger
seat and prevent the side airbag in the seat backrest from
deploying properly .
• Never use cushions, pillows, blankets or similar items on the
front passenger seat . The additional padding will prevent the
weight-sensing mat in the seat from accurately registering the
child restraint or person on the seat and prevent the Advanced
Airbag System from functioning properly.
• If you must use a child restraint on the front passenger seat
and the child restraint manufacturer's instructions require the use
of a towel , foam cushion or something else to properly position
the child restraint, make certain that the PASSENGER AIR BAG OFF
light comes on and stays on whenever the child restraint is
i nstalled on the front passenger seat .
• If the PASSENGER AIR BAG OFF light does not come on and stay
on, immediately install child restraint in a rear seating position
and have the airbag system inspected by your Audi dealer. •

th e safety be lt pr etensioners dep ends on the decele ration
m easu re d by the crash se nso rs and regi stered by the e lec troni c
control unit . Crash s eve rity depends on speed and dec eleration 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 wi ll not deploy . If the safety
belt is not being used, the first stage deploys, followed by the
second stage after a much later time in the crash sequence.
If the electronic control unit registers a crash of medium severity,
the first stage of the airbag deploys followed by the second stage at
a much later t ime in the crash sequence · regardless of whe ther the
safety belt is being used or not. In higher severity crashes as regis ­
tered by the e lectronic contro l unit, both the fi rst and second stages
deploy almost at the same time.
On the passenger side, regardless of safety belt use, the airbag will
be turned off if the weight on the passenger seat is less than the
amount programmed in the electronic control unit. The front airbag
on the passenger side wi ll a lso be turned off if one of the child
safety seats that has been certified under Federal Motor Vehicle

More important things to know about front
airbags
F ig . 205 In fl at ed front
airb ags
Safety belts are important to he lp keep front seat occupants in the
proper seated position so tha t airbags can unfold proper ly and
provide supplemental protection in a fronta l collision.
The fron t airbags are designed to provide addit ional protection for
the chest and face of the driver and the front seat passenger when:
• safety belts are worn properly,
• the seats have been positioned so that the occupant is properly
seated as far as possib le from the airbag,
• and the head restraints have been properly adjusted .
Because airbags inflate in the blink of an eye with great force , things
you have on your lap or have p laced on the seat cou ld become
dangerous projectiles, and be pushed into you if the airbag inflates .
When an airbag deploys, fine dust is released . This is norma l and is
not caused by a fire in the vehicle. This dust is made up mostly of a
powder used to lubricate the airbags as they d eploy . It could irritate
skin.
It is important to remember that while the supplemental airbag
system is designed to reduce the likelihood of serious injuries, other
injuries, for example swelling, bruising and minor abrasions, can
a lso happen when airbags inflate. Airbags do not pro tect the arms •

• i n sid e collis io ns,
• i n rea r- e nd collisi ons ,
• in ro llovers,
• when th e c ras h de celerat io n measur ed by the a irba g system is
less than the minimum threshold needed for a irbag deployment as

& WARNING
Sitting in the wrong position can increase the risk of serious injury
in crashes .
• To reduce the risk of injury when the airbags 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 position or too close to the
airbag can be seriously injured by an airbag as it unfolds with
great force in the blink of an eye=> page
214.
& 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 Advanced 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 arm rest, 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 circumstances and
the PASSENGER AIR BAG OFF light does not come on and stay on, i mmediately install the rear-facing child safety seat in a rear
seating position and have the airbag system inspected by your
Audi dealer .
& WARNING
Objects between you and the airbag will increase the risk of injury
in a crash by interfering with the way the airbag unfolds or by
being pushed into you as the a irbag 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 airbags during
braking or other sudden maneuver and become dangerous projec ­
tiles that can cause serious personal injury if the airbags inflate .
• Never place or attach accessories or other objects (such as
cupholders, telephone brackets , large, heavy or bulky objects) on
the doors , over or near the area marked "AIRBAG" on the steering
wheel , instrument panel , seat backrests or between those areas
and yourself . These objects could cause injury in a crash , espe­
cially when the airbags inflate .
• Never recline the front passenger's seat to transport object s.
Items can also move into the area of the side airbag or the front ..,
