& WARNING (continued)
• Airbag work most effectively when used with properly worn
safety belts .
• Therefore, always wear your safety belts and make sure that
everybody in your vehicle is properly restrained .
& WARNING
A person on the front passenger seat, especially infants and small
children, will receive serious injuries and can even be killed by
being too close to the airbag when it inflates .
• Although the Advanced Airbag System in your vehicle is
designed to turn off the front passenger airbag if an infant or a
small child is on the front passenger seat, nobody can absolutely
guarantee that deployment under these special conditions is
impossible in all conceivable situations that may happen during
the useful life of your vehicle.
• The Advanced Airbag System can deploy in accordance with
the "low risk" option under the U.S. Federal Standard if a child that
is heavier than the typical one-year old child is on the front
passenger seat and the other conditions for airbag deployment
are met.
• Accident statistics have shown that children are generally safer
in the rear seat area than in the front seating position.
• For their own safety, all children, especially 12 years and
younger, should always ride in the back properly restrained for
their age and size . •
Advanced front airbag system
Your vehicle is equipped with a front Advanced Airbag System in
compliance with United States Federal Motor Vehicle Safety Stan ­
dard 208 as applicable at the time your vehicle was manufactured. The
front Advanced Airbag System supplements the safety belts to
provide additional protection for the driver's and front passenger's
heads and upper bodies in frontal crashes . The airbags inflate only
in frontal impacts when the vehicle deceleration is high enough.
The front Advanced Airbag System for the front seat occupants is
not a substitute for your safety belts . Rather, it is part of the overall
occupant restraint system in your vehicle. Always remember that
the airbag system can only help to protect you, if you are sitting
upright, wearing your safety belt and wearing it properly. This is why
you and your passengers must always be properly restrained, not
just because the law requires you to be.
The Advanced Airbag System in your vehicle has been certified to
meet the "low risk" requirements for 3 and 6 year -old children on the
passenger side and very small adults on the driver side. The low risk
deployment criteria are intended to help reduce the risk of injury
through interaction with the front airbag that can occur, for
example, by being too close to the steering wheel and instrument
panel when the airbag inflates.
In addition, the system has been certified to comply with the
"suppression" requirements of the Safety Standard, to turn off the
front airbag for infants 12 months old and younger who are
restrained on the front passenger seat in child restraints that are
listed in the Standard=>
page 159, "Child restraints and Advanced
Airbags" .
"Suppression" requires the front airbag on the passenger side to be
turned off if:
• a child up to about one year of age is restrained on the front
passenger seat in one of the rear-facing or forward-facing infant
restraints listed in Federal Motor Vehicle Safety Standard 208 with
which the Advanced Airbag System in your vehicle was certified. For
a listing of the child restraints that were used to certify your
vehicle's compliance with the US Safety Standard=>
page 159,
• weight less than a threshold level stored in the control unit is
detected on the front passenger seat. .,

Whe n a person is detected on the front passenger seat, weighing
more than the to tal weight of a child t hat is about 1 year old
restrained in one of the rear-facing or forward -facing infant
restraints (listed in Federa l Motor Vehicle Safety Standard 208 with
which the Advanced Airbag System in your vehicle was certified), the front airbag on the passenger side may or may not deploy .
The
PA SSENGER AIR BAG OFF light comes on when the e lectronic
control unit detects a total weight on the front passenger seat that
requires the front a irbag to be turned off . If the
PA SSENGER AIR BAG
O FF
light does not come on, the front airbag on the passenger side
has not been tu rned off by the contro l u nit and can dep loy if the
control unit senses an impact that meets the conditions stored in its
memory .
I f the total weight on the front passenger seat is more than that o f
a typical
1 year -old, but less than the we ight of a small adult, the
front airbag on the passenger side may dep loy (the
PA SS ENGER AIR
BAG OFF
l ight does not come on).
For example , the airbag may deploy if :
• a small ch ild that is heavier than a typ ical 1 year-o ld child is on
the front passenger seat (regardless of whether the child is in one
of the child sa fety seats listed ~ page
159),
• a child who has outgrown child res traints is on the front
passenger seat.
I f the front passenger airbag is turned off, the
PASSENGER AIR BAG

light in the cen ter of the instrument panel wi ll co me on and stay
on .
T he front airbag on the passenge r side may
not deploy (the
PASS ENGER AIR BAG OFF light does not illuminate and stay lit) if:
• a small adult or teenager is on the front passenger seat
• a passenger who is not sitting upright with their back against a
non -reclined backrest with their feet on the vehicle floor in front of
the seat is on the front passenger seat.
I f the front passenger airbag dep loys, the Federal Standard requires
the airbag t o meet the "low risk" deployment criteria to help reduce

dep loyment occurs in those crashes that ta ke place at l ower decel ­
erations as defined in the electronic control unit~ page
146.
Alway s remembe r: Even though your vehicle is equipped with
Advanced Airbags, the safes t place for chi ldren is properly
restrained on the back seat. Please be sure to read the important
informat ion in t he sections tha t follow a nd be sure to heed a ll of the
WARNINGS.
& WARNING
To reduce the risk of injury when an airbag inflates , always wear
s afety belts prope rly.
• If you are unrestrained , leaning forward , sitt ing s ideways or out
of position in any w ay, your risk of injury i s mu ch higher .
• You will al so receive se riou s injurie s and could even be killed if
you are up against the airbag or too clo se t o it when it inflate s -
even with an Advanced Airbag => page 135 .
& WARNING
A child in a rearward -facing child safety seat in stalled on the front

& WARNING (continued)
• 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,
immediately install the rear-facing child safety seat in a rear
seating position and have the airbag system inspected by your
Audi dealer.
& WARNING
If, in exceptional 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 for use on a front seat with a
passenger front and side airbag.
• Never put the forward-facing child restraint up against or very
near the instrument panel.
• Always move the passenger seat into its rearmost position in
the seat's fore and aft adjustment range, as far away from the
airbag as possible, before installing the forward-facing child
restraint . 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. •
Advanced Airbag System components
The front passenger seat in your vehicle has a lot of very important
parts of the Advanced Airbag System in it. These parts include the
weight-sensing mat, sensors, wiring, brackets, and more. The func­
tion of the system in the front passenger seat is checked by the elec ­
tronic control unit when the ignition is on. The control unit monitors
the Advanced Airbag System and turns the airbag indicator light on
when a malfunction in the system components is detected. The
function of the airbag indicator light is described in greater detail below
. Because the front passenger seat contains important parts
of the Advanced 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 doing its job in
a crash .
The front Advanced Airbag System consists of the
following:
• Crash sensors in the front of the vehicle that measure vehicle
acceleration/deceleration to provide information to the Advanced
Airbag System about the severity of the crash.
• An electronic control unit, with integrated crash sensors for front
and side impacts. The control unit "decides" whether to fire the
front airbags based on the information received from the crash
sensors. The control unit also "decides" whether the safety belt
pretensioners should be activated.
• An Advanced Airbag with gas generator for the driver inside the
steering wheel hub .
• An Advanced Airbag with gas generator inside the instrument
panel for the front passenger.
• A weight-sensing mat under the upholstery padding of the front
passenger seat cushion that measures the total weight on the seat.
The information registered is sent continuously to the electronic
control unit to regulate deployment of the front Advanced Airbag on
the passenger side.
• An airbag monitoring system and indicator light in the instru ­
ment cluster ~
page 146.
• The PASSENGER AIR BAG OFF light comes on and stays on in the
center of the instrument panel~
page 147, fig. 113 and tells you
when the front Advanced Airbag on the passenger side has been
turned off.
• A sensor below the safety belt latch for the front seat passenger
to measure the tension on the safety belt. The tension on the safety
belt and the weight registered by the weight -sensing mat help the
control unit "decide" whether the front airbag for the front ..

veh ic le dece lerat ion is h igh enou gh to deploy th e airbags.
Front airbags will not deploy:
• if the ignition is switched off when a crash occurs,
• in s ide collisions ,
• i n rea r- e nd c ollisions ,
• in ro llovers,
• when th e cras h d eceler ation m easured b y th e a irba g sys te m i s
less than the minimum threshold needed for airbag dep loyment as

The front passenger airbag will also not deploy :
• when the fron t passenger s eat i s not o ccupied,
• when the weight o n th e front pass enger seat as se nsed by the

pas senger side has to be tu rned off b y the e lectronic cont ro l unit
(th e PASSENGER AIR BAG OFF l ig ht co me s on and sta y s on ).
& WARNING
Sitting in the wrong position can increase the risk of ser ious 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 137.
Controls and equip­ ment Safety first
Vehicle operation
& 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 w ith 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, immediately 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 in crease the risk of injury
in a crash by interfering 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 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 cup
holders , 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 objects.
Items can also move into the area of the side airbag or the front

Audi dealer .
• A tight tether or other str ap on a rearward-fac ing child restr aint
attached to the front pas senger seat can put too much pressure
on the weight-sensing mat in the seat and reg ister more weight
than i s 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
s erious or even fatal injury to the child .
• If, in exceptional circumstance s, you mu st in stall a forward ­
fac ing child restra int on the front passenger seat , always move the
seat into its rearmost position in the seat 's fore and aft ad just ­
ment range , as far away from the airbag a s possible . The backrest
must be adjusted to an upright position . Make sure that the
PASSENGER AIR BAG OFF light comes on and stay s on all the time
whenever the ignition is switched on .
& WARNING
• If the PASSENGER AIR BAG OFF light does 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 .

Repair, care and disposal of the airbags
Parts of the airbag system are insta lled at many different places on
your Au di. In sta ll in g, re moving, ser vic in g or re pair in g a part in an
area of the vehicle can damage a part of an a irbag system and
pre ven t that system fro m wo rki ng p rope rly in a co llision .
There are some important things you have to know to make sure
that the effectiveness of the system will not be impai red an d that
d iscarded components do not cause inju ry or po llute t he e nv iron ­

& WARNING
Improper care , servicing 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 obje cts su ch as cup holders 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 moi stened with plain water . Solvents or cleaners
c ould 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 parts of the airbag system.
• All work on the steering wheel , instrument panel , front seats or
electrical system (including the installation of audio equipment ,
c ellular telephones and CB radios , etc .I must be performed by a
qualified technician who has the training and special equipment
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 .
Vehicle care Do-it-yourself service Technical data

& 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

Safety first
Knee airbags
Description of knee airbags
Airbag system
The airbag system can provide supplemental protection
to properly restrained front seat occupants.
Fig. 114 Driver 's
airbag
The airbag for the driver is located in the instrument panel under ­
neath the steering wheel=> fig. 114, the airbag for the passenger is
at about the same height in the instrument panel underneath the
glove compartment.
The knee airbag offers additional protection to the driver's and
passenger's knees and upper and lower thigh areas as a supple­
ment to the safety belts.
If the front airbags deploy, the knee airbags also deploy in frontal
collisions above a certain severity=>
page 144, "More importan t
things to know about front airbags".
Besides their normal safety function, safety belts work to help keep
the driver or front passenger in position in case of a frontal collision
so that the airbags can provide protection.
The airbag system is not a substitute for your safety belt. Rather, it
is part of the overall occupant restraint system in your vehicle.
Always remember that the airbag system can only help to protect
you if you are wearing your safety belt and wearing it properly. This •
Vehicle care I I irechnical data

is why you should always wear your safety belt, not just because the
law requires you to do so~
page 125, "General notes".
The safety belt buckle for the driver and front seat passenger have switches that tell the airbag control module if the safety belt is
being used or not . If the safety belt is being used, the knee airbag
will deploy at a slightly higher rate of deceleration than if the belt is
not be ing used. Therefore, in a part icular collision, it is possible that
an airbag will not deploy at a seating position where the safety belt
is being used but will inflate a t the position where the safety belt is
not being used .
Remember too, airbags wi ll deploy only once and only in certain
kinds o f accidents -your safety belts are a lways there to offer
protection in those accidents in which airbags are not supposed to
deploy or when they have already deployed, for example when your
vehic le strikes or is struck by another after the first collision .
This is just one of the reasons why an airbag is not a substitute for
the safety be lt . The airbag system works most effectively when used
with the safety bel ts. Therefore, always wear your safety belts
correctly .
It is important to remember that while the supplemental airbag
system is des igned to reduce the likelihood of serious injuries, other
injuries, for example, swelling, bruising, and minor abrasions can
a lso be associated with airbags.

& WARNING
An inflating knee airbag can cause serious injury. Wearing safety
belts incorrectly and improper seating positions increase the risk
of serious personal injury and death whenever a vehicle is being
used .
• The airbag system cannot protect you properly if you are
seated too close to any of the airbag locations. When adjusting

their seat positions, it is important that both the driver and the
front passenger keep their upper bodies and knees at the
following minimum safe distances:
- 1
O inches (25 cm) between the chest and the steering
wheel /instrument panel .
- 4 inches (10 cm) between the knees and the lower part of the instrument panel .
• The risk of personal injury increases if you lean forward or to
the side, or if the seat is improperly positioned and you are not
wearing your safety belt . The risk increases even more should the
airbag deploy .
• Always make sure that the knee airbag can inflate without
interference . Objects between yourself and the airbag can
increase the risk of injury in an accident by interfering with the
way the airbag deploys or by being pushed into you as the airbag
deploys .
- No persons (children) or animals should ride in the footwell
in front of the passenger seat . If the airbag deploys , this can
result in serious or fatal injuries .
- No objects of any kind should be carried in the footwell area
in front of the driver's or passenger's seat . Bulky objects (shop­
ping bags , for example) can hamper or prevent proper deploy­
ment of the airbag . Small objects can be thrown through the
vehicle if the airbag deploys and injure you or your passengers .
• Make sure there are no cracks, deep scratches or other damage
in the area of the instrument panel where the knee airbags are
located .
• If children are incorrectly seated, their risk of injury increases in
the case of an accident=>
