& 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 226.
• The PASSENGER AIR BAG OFF light comes on and stays on in the
center of the instrument panel~
page 227, fig. 213 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 ..

& 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 217.
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 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, 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 maneuvers and become dangerous
projectiles 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 . ...

& WARN ING (continued )
• Never recline the front passenger' s seat to transport obje cts.
Item s can als o move into the area of the side airbag or the front
airbag during br aki ng or in a sudden maneuver . Objects near the
airbags can become projectiles and cause injury , particularly when
the seat is re clined .
& WARNING
The fine dust created when airbags deploy can cause breathing
problems for people with a histo ry of asthma or other breathing
c onditions.
• To reduce the ri sk of breathing p roblems , tho se with asthma or
other respiratory conditions should get fresh air right away by
getting out of the veh icle or opening windows or door s.
• If you are in a collision in which airbags deploy , wash your
hands and face w ith mild soap and water before eat ing.
• Be careful not to get the dust into your eyes, or into any cuts or
s crat ches .
• If the residue should get into your eyes , flush them with
water .•

• 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 ­

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 ­
ment .
& 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 objects such as cupholders 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 .

t he control unit, the side airbags will not be triggered, even though
the car may be badly damaged as a result of the collision . It is not
possible to define an airbag triggering range that wi ll cover every
possible angle of impact, since the circumstances will vary consid­
erably between one collision and another . Important factors
include, for example, the nature (hard or soft) of the impacting
object, the angle of impact, vehicle speed, etc.=>
page 233, "Impor ­
tant safety instructions on the side airbag system".
Aside from their normal safety function, safety belts work to help keep the driver or front passenger in position in the event of a side
collision so that the side airbags can provide protection .
The airbag system is
not a substitute for your safety belt . Rather, it
is part of the overa ll occupant restraint system in your vehicle .
Always remember that the side airbag system can on ly help to
protect you if you are wearing your safety be lt and wearing it prop­
erly . This is another reason why you should always wear your safety
belts, not just because the law requires you to do so=>

It is important to remember that while the supplemental side airbag
system is designed to reduce the likelihood of serious injuries, other
injuries, for example, swel ling, bruising, and minor abrasions can
a lso be associated with deployed s ide airbags. Remember too, side
airbags wil l deploy only once and only in certain kinds of accidents
- your safety belts are always there to offer protection.
Vehicle damage, repair costs or even the lack of vehicle damage are not necessari ly an indication of over -sensitive or failed airbag acti ­
vation. In some collisions , both front and side airbags may inflate.
Remember too, that airbags will deploy only once and only in
certain kinds of collis ions - your safety belts are always there to
offer protection in those accidents in which airbags are not
supposed to deploy or when they have already dep loyed.

Advanced front airbag system and children
Your vehicle is equipped with an "Advanced Airbag System" in
compliance with United States Federal Motor Veh icle Sa fety Stan ­
dard ( FMVSS) 208 as applicable at the time your vehicle was manu ­
f actured .
Controls and equip­ ment Safety first Vehicle operation 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 small adu lts on the driver side. The low risk
deployment crite ria are intended to reduce the risk of injury th rough
interaction with the airbag that can occur, for example, by being too
close to the steering wheel and instrument panel when the airbag
inf lates . In addit ion, the system has been cert ified to comply with
the "suppression" requirements of the Safety Standard, to turn off
the front airbag for infants up to 12 months who are restrained on
the front passenger seat in child restraints that are listed in the
Standard.
Even though your vehic le is equipped with an Advanced Airbag
system, all children, especially those 12 years and younger, should
a lways ride in the back seat properly restrained for their age and
s ize . The airbag on the passenger side makes the front seat a poten­
tia lly dangerous p lace for a chi ld to ride. The front seat is not the
safest p lace for a child in a forward -facing child safety seat. It can be
a very dangerous place for an infant or a larger child in a rearward­
facing seat. •
Advanced Airbags and the weight-sensing
mat in the front seat
The Advanced Airbag System in your vehicle detects the presence
of an infant or child in a chi ld restraint on the front passenger seat
using the weight -sensing mat in the seat cushion and the sensor
below the safety belt latch on the front passenger seat that
measures the tension on the safety be lt .
The weight -sensing mat measures t otal weight of the child and the
child safety seat and a chi ld blanket on the front passenger seat. The
we ight o n the front passenger seat is related to the design of the
child restraint and its "footprint" , the size and shape of the bottom
of the child restraint as it sits on the seat. The weight of a child
restraint and its "footprint" vary for different kinds of child

Important safety instructions for using child
safety seats
Correct use of child safety seats substantially reduces the
risk of injury in an accident!
As the driver, you are responsible for the safety of every
­
body in the vehicle, especially children:
- Always use the right child safety seat for each child and
always use it properly~
page 243.
-Always carefully follow the child safety seat manufac­
turer's instructions on how to route the safety belt prop­
erly through the child safety seat.
- When using the vehicle safety belt to install a child safety
seat , you must first activate the convertible locking
retractor on the safety belt to prevent the child safety
seat from moving~
page 248.
-Push the child safety seat down with your full weight to
get the safety belt really tight so that the seat cannot move forward or sideways more than one inch (2.5 cm).
- If a strap or tether is being used to tie the child safety
seat to the front passenger seat, make sure that it is not
so tight that it causes the weight-sensing mat to
measure more weight than is actually on the seat.
Always remember: Even though your vehicle is equipped with an
Advanced Airbag system, all children, especially those 12 years and
younger, should always ride in the back seat properly restrained for
their age and size. ..,
