authorized Audi dealer.
• A tight tether o r other strap on a rearward -facing child
restraint attached to the front pa ssenger seat can put too much
pressure on the weight -sensing mat in the seat and register more
weight than i s actually on the seat . The heavier weight regi stered
can make the system work as though an adult were on the seat
and deploy the Advan ced Airbag when it mu st be suppre ssed
causing serious or even fatal injury to the child .
• If , in exceptional circumstanc es, you must install a forward­
facing child restraint on the front passenger seat, always move
the seat into its rearmost po sition in the seat' s fore and aft adjust­
ment range, as far away from the airbag as possible . 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.
& WARNING
• If the PASSENGER AIR BAG OFF light doe s 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 authorized Audi
dealer before transporting anyone on the front passenger seat .

& WARNING
Improper care , serv icing 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 moistened with plain water . Solvent s or cleaners
could 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 part s of the airbag system .
• All work on the steering wheel, instrument panel , front seats
or electrical sy stem (including the installation of audio equip­
ment, cellular telephones and CB radios, etc. ) must be performed
by a qualified technician who has the training and special equip­ ment 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 . ..,_

& 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.
Controls and equip­ ment Safety first Vehicle operation
& WARNING
(cont inued )
• 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:
- 10 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~

• in rear-end collisions
• in rollover s.
In some types of accide nts the front a irbags a nd side a irbags may be
t rig gere d together.
& WARNING
• Safety belts and the airbag system will only provide prote ction
when occupants are in the proper seating position=> page
219 .
• If the airbag indicator light comes on when the vehicle is being
used, have the system inspected immediately by your authorized
Audi dealer. The airbag may not work properly when the vehicle acceleration in a side collision is high enough to activate the
airbag. •
How supplemental side airbags work
Side airbags deploy ins tan tly an d can help reduce the risk
o f upper torso injuries for occupants who are properly
restrained.

Child Safety
Important things to know
Introduction
The rear seat is generally the safest place in a collision.
The physical pr in ci ples o f wha t happens w hen yo ur vehicl e is in a crash
app ly a lso to children=>
page 191, "What happens to occupants not
wearing safety be lts?". But unlik e adu lts and teenagers, the ir
muscles and bones are not fully developed. In many respects c hildren
are at greate r risk of ser io us injury in cras hes than adults .
Because children 's bodies a re not f ully deve loped, they require
restraint systems especially designed fo r their size, weight, and body
st ruct ure. Many cou ntries and all states of t he Unite d States and
prov inces of Canada have laws req uiring the use of approved ch ild
restrain t sys tems for infan ts an d sm all ch ild ren .
I n a fronta l crash at a speed of 20 -35 mph (30-56 km/h) the forces
act ing o n a 13- pound (6 kg) infant w ill be more than 20 times the
we ight of the ch ild . This means the we ight of the child wo uld
suddenly be more than 260 po unds (120 kg). Unde r these conditions,
only a n app ropr iat e child restra int proper ly used can red uce the risk
o f serious injury. Child restrai nts must be used properly to be e ffec­
t ive. Used i mpro perly, t hey can increase the risk of serio us injury in an
acc ident.
C onsult the ch ild safety seat manufacturer's instr uctions in order to
be sure the seat is r ight for you r child's size=>
page 224, "Important
safety instructions fo r using child safety seats". P lease be s ure to
read and heed a ll of the important informa tion and WAR NINGS
about chi ld safety, Advanced Airbags, an d the installation of child
restra in ts in this chapte r.
There is a lot you need to know about the Advanced Airbags in your
vehicle and how t hey wo rk when inf ants and childre n in child
restra ints are on the front passenger seat. Beca use of t he large

nt of importa nt info rmation, we cannot repeat i t all he re. We
urge you to read the detailed information in th is owne r's man ua l
abou t airbags and t he Advanced A irbag Syste m in your vehicle and the
very important information abo ut transporting c hildren on the front
p assenger se at. P lea se be sure to heed the WARNIN GS - they a re
extremely important for your safety and the safety of your passe n­
gers, especially infan ts and small ch il dre n.
& WARNING
• Accid ent statisti cs have shown that children are generally safer
in the rear seat area than in the front seating position. Always
re strain any child age 12 and under in the rear.
• All vehicle occupants and especially children must be
restrained properly when ever riding in a vehicle. An unre strained
or improperly restrained child could be injured by striking the
interior or by being ejected from the vehicle during a sudden
maneuver or impact. An unrestrained or improperly rest rained
child is also at greater risk of injury or death through contact with
an inflat ing airbag .
• A suitable child restraint properly installed and used at one of
the rear seating posi tions provides the highest degree of protec­
tion for infants and small children in most accident situations.
& WARNING
Children on the front seat of any car even with Advanced Airbags
can be seriously injured or even killed when an airbag inflates. A
c hild in a rearward -facing child safety seat ins talled on the front
passenger seat will be seriously injured and can be killed if the
front airbag inflate s.
• The inflating airbag will hit the child safety seat or infant
c arrier with great force and will sma sh the child safety seat and
child aga inst the backrest, or door. •

and for the different models of the same kind of child restraint
offered by child restraint manufacturers.
The weight ranges for the individual types, makes and models of ch ild
restraints that the NHTSA has specified in the Safety Standard
together with the weight ranges of typical infants and typical 1 year­
old child have been stored in the control unit of the Advanced Airbag
System. When a child restraint is being used on the front passenger
seat with a typical 1 year-old chi ld, the Advanced Airbag System
compares the weight meas ured by the weight sensing mat with the
information stored in the electronic control unit .
The electronic contro l unit a lso registers the tension on the front
passenger safety belt. The tension on the safety belt for the front
passenger seat will be different for an adult who is properly using the
safety belt as compared to the tension on the belt when it is used to
attach a child restraint to the seat . The sensor below the latch for the
safety belt for the front seat passenger measures the tension on the
belt. The input from this sensor is then used with the weight to
"decide", whether there is a child restraint with a typical 1 year-old
child on the front passenger seat and whether or not the airbag must
be turned off .•
Child restraints and Advanced Airbags
Regardless of the child restraint that you use, ma ke sure that it has
been certified to meet United States Federal Motor Vehicle Safety
Standards and has been ce rtified by its manufacturer for use with an
airbag . Always be sure that the child restraint is properly installed at
one of the rear seating positions. If in exceptional circumstances you
must use it on the front passenger seat, carefully read all of the infor­
mation on ch ild safety and Advanced Airbags and heed all of the
app licab le WARNINGS. Make certain that the child restra int is
correctly recognized by the weight-sensing mat inside the front
passenger seat, that the front passenger airbag is turned off and that
the airbag status is always correctly signaled by the
PASSENGER AIR
BAG OFF
light.
Controls and equip­ ment Safety first Vehicle operation
Many types and models of child restra
ints have been available over
t he years, new models are introduced reg ularly incorpo rating new
and improved designs and older models are taken out of product ion.
Chi ld restraints are not standardized. Child restraints of the same
type typ ically have d ifferent weights and sizes and differe nt 'foot­
prints,' the size and shape of the bottom of the child restraint that
sits on the seat, when they are installed on a vehicle seat . These
differences make it virtually impossib le to certify compliance with
t he requirements for advanced airbags with each and every chil d
restra int that has ever been sold in the past or will be sold over the
course of the useful life of your vehicle.
For this reason, the United States Nationa l Highway Traffic Safety
Administration has published a list of specific type, makes and
mode ls of child restra ints that must be used to cert ify compliance of
the Advanced Airbag System in yo ur vehicle with the suppression
requirements of Federal Motor Veh icle Safety Standard 208. These

& WARNING
Not using a child safety seat, us ing the wrong child safety seat or
improperly in stalling a child re straint in crea se s the ri sk of serious
personal injury and death .
• All vehicle oc cupants and e specially children mu st always be
restrained properly whenever riding in a vehicle.
- An unrestrained or improperly restrained child can be injured or killed by being thrown against the inside of the
vehicle or by being ejected from it during a sudden maneuver
or impact .
- An unre strained or improperly restrained child is at much
greater risk of injury or death by being struck by an inflating
airbag .
• Commercially a vailable child safety seats are requi red to
c omply with U .S. Federal Motor Vehicle Safety Standard (FMVSS )
213 (in Canada CMVSS 213 ).
- When buying a child restraint, select one that fits your child
and the vehicle.
- Only u se child restraint sy stem s that fully contact the flat
portion of the seat cushion . The child rest raint must not tip or
lean to either side . Audi does not recommend using child
s a fety seats that rest on legs or tube-like frames. They do not
provide adequate contact with the seat .
Controls and equip­ ment Safety first Vehicle operation
& WARNING
(co ntinued )
-Always heed all legal requirements pe rtaining to the in stal­
lation and use of child safety seat s and carefully follow the
inst ructions provided by the manufacturer of the seat you are
using.
• Never allow child ren under 57 inches (1.5 meters ) to wear a
normal safety belt . They must always be restrained by a prop er
child restraint system . Otherwise , they could sustain injuries to
the abdomen and neck areas during sudden braking maneuvers or accidents.
• Never let more than one child occupy a child safety seat.
• Never let babies or olde r children ride in a vehicle while sitting
on the lap of another passenger.
-Holding a child in your arms is never a sub stitute for a child
restraint system .
- The stronge st p ers on could not hold the child with the force s
that e xist in an accident . The child will strike the interio r of the
v ehicle and can also be struck by the pa ssenger.
- The child and the passenger can also injure each other in an
accident.
• Never install rear-facing child safety seats or infant carriers on
the front pas senger seat. A child will be seriously injured and can
be killed when the passenger airbag inflates - e ven with an
Advanced Airbag Sy stem .
• The inflating airbag will hit the child safety seat or infant
c arrier with great force and will sma sh the child safety seat and
child aga inst the bac krest, center arm rest, door o r roof.
• Always in stall rear -facing child safety seats or infant carriers
on the rear seat .
• Forward-facing child safety seats installed on th e front
