Important safety instructions on the side
airbag system
Airbags are only supplemental restraints. Always prop­ erly wear safety belts and ride in a proper seating posi­
tion.
Th ere is a lot that you and your passengers must know and act accord­
ing ly to help the safety be lts and a irbags do their job to provide
supplemental protection .
& WARNING
An inflating side airbag can cause serious or fatal injury. Improp­
erly wearing safety belts and improper seating positions increase
the risk of serious personal injury and death whenever a vehicle is
being used.
• In order to reduce the risk of injury when the supplemental
side airbag inflates:
- Always sit in an upright position and never lean against the
area where the supplemental side airbag is located.
- Never let a child or anyone else rest their head against the
side trim panel in the area where the supplemental side airbag
inflates.
- Always make sure that safety belts are worn correctly,
- Do not let anyone sitting in the front seat put their hand or
any other parts of their body out of the window.
• Always make sure that the side airbag can inflate without
interference.
-Never install seat covers or replacement upholstery over the
front seatbacks that have not been specifically approved by
Audi.
- Never use additional seat cushions that cover the areas
where the side airbags deploy.
Controls and equip­ ment Safety first Vehicle operation
& WARNING
(continued)
- Damage to the original seat covers or to the seam in the area
of the side airbag module must always be repaired immedi­
ately by an authorized Audi dealer.
• Objects between you and the airbag can increase the risk of
injury in an accident by interfering with the way the airbag unfolds
or by being pushed into you as the airbag inflates. -Never place or attach accessories or other objects (such as
cup holders, telephone brackets, or even large, bulky objects)
on the doors, over or near the area marked "AIRBAG" on the
seat backrests.
- Such objects and accessories can become dangerous projec­
tiles and cause injury when the supplemental side airbag
deploys.
- Never carry any objects or pets in the deployment space
between them and the airbags or allow children or other
passengers to travel in this position.
• Always use the built-in coat hooks only for lightweight
clothing. Never leave any heavy or sharp -edged objects in the
pockets that may interfere with side airbag deployment and can
cause personal injury in an accident.
• Always prevent the side airbags from being damaged by heavy
objects knocking against or hitting the sides of the seatbacks.
• The airbag system can only be triggered once. If the airbag has
been triggered, the system must be replaced by an authorized
Audi dealership.
• Damage (cracks, deep scratches etc.) to the original seat covers
or to the seam in the area of the side airbag module must always
be repaired immediately by an authorized Audi dealer.
• If children are seated improperly, their risk of injury increases
in the case of an accident~
page 167, "Child Safety".
• Never attempt to modify any components of the airbag system
in any way. .,

Side curtain airbags
Description of curtain airbags
The curtain airbags can provide supplemental protection
to properly restrained occupants.
F ig . 1 42 C urtain
a irb ag, dr iver 's side:
s ide c urt ain ai rbag
loc ation
The side curtain airbags are located on bot h sides of t he interior
a b ove the fro nt an d rear side windows ~ fig. 1 42. T hey ar e identified
by the word "AIRBAG" on t he w indshield frame and the center roo f
pillar .
Th e side curtain a irbag system supplements t he safety belts and ca n
help to reduce the risk of injury for occupants' heads and upper torso
on t he side of the vehi cle th at i s st ru ck in a s ide collision. The s ide
curtain airbag inflates in side impacts and only when t he veh icle
accele ration registe red by the co ntrol u nit is high enoug h. If t his ra te
is below the reference va lue programmed into the control unit, the
side airbags w ill not be triggered, eve n though the car may be badly
damaged as a result of the co llision . It is not possib le to define an
airbag trigger ing range that w ill cover every possible ang le of impact,
sinc e the circumstances will vary co nsiderab ly between one col lision
and another . Important factors incl ude, for example, the nature
(hard or soft) of the impact ing object, the a ngle of impact, vehicle
speed, etc.~
page 165.
Aside from the ir normal safety fu nction, safe ty be lts work to he lp
keep the driver or front passenger in posit ion in the event of a co lli­
sion so that the side curtain airbags can provide protection.
T he airbag system is not a substitute for your safe ty belt. Rathe r, it is
part of the overall occupant restraint system in your veh icle. Always
remembe r th at the airbag system can on ly help to protect you if yo u
are wear ing your safety belt and wearing it proper ly . This is another
reaso n why yo u sho uld always wea r your sa fety be lts, no t jus t becau se
the law requires you to do so~
page 135, "General notes".
It is impo rtan t to remember that while the side curtain airbag sys tem
is des igned to he lp reduce the like lihood of ser ious injur ies, other
injuries, for example, swe lling, bruising, and minor abrasions can
also be assoc iated with t hese airbags upon deployment . Remembe r
too, these airbags w ill dep loy only once and on ly in certain kinds of
a cci den ts -your safe ty belts a re always there to offer protection .
The side curtain airbag system basically consists of:
• The e lec tron ic cont rol mo dule and e xte rnal si de impact sensors
• The side curtain air bags above the front and rear side windows
~

• The airbag indicator light in the instrument panel
The airbag system is monitored electronically to make certain it is
functioning properly at all times. Each time you turn on the ignition,
the airbag system indicator light will come on for a few seconds (self
diagnostics).
The side curtain airbag is not activated:
• if the ignition is turned off,
• in side collisions when the acceleration measured by the sensor is
too low,
• in rear-end collisions,
• in rollovers.
& WARNING
• Safety belts and the airbag system will only provide protection
when occupants are in the proper seating position =>
page 73,
"General recommendations" .
• If the airbag indicator light comes on when the vehicle is being
used , have the system inspected immediately by your authorized
Audi dealer. The side curtain airbag may not work properly even
when the vehicle acceleration in a side collision is high enough to
activate the airbag. •
Safety first Vehicle OP-eration
Airbag system
How side curtain airbags work
Side curtain airbags can work together with side airbags
to help reduce the risk of head and upper torso injuries for
occupants who are properly restrained.
Fig. 143 Illustration
of principle: Inflated
s ide curtain airbags on
the left side
The side curtain airbags inflate between the occupant and the
w indo ws on the side of the vehicle that is struck in a side collision
=> fig . 143.
When the system is triggered, the side curtain airbag is filled with
propellant gas and breaks through a seam above the front and rear
side windows identif ied by the AIRBAG label. In order to help provide
this additional protection, the side curtain airbag must inflate with in
the blink of an eye at very high speed and with great force. The side
curtain airbag could injure you if your seating position is not proper or
upright or if items are located in the area where the supplemental
side curtain airbag inflates. This applies especially to ch ildren
::::>page 167.
Although they are not a soft pillow, side curtain airbags can "cushion"
the impact and in this way they can help to reduce the risk of injury to
the head and the upper part of the body.
A fine dust may develop when the airbag deploys. This is quite no rmal
and does not mean there is a fire in the vehicle. •

in. WARNING
Improperly wearing safety belts and improper seating positions
increase the risk of serious personal injury and death whenever a
vehicle is being used.
• Never let occupants place any parts of their bodies in the area
from which the side curtain airbags inflate.
• Always make sure that the side curtain airbags can inflate
without interference. Unsuitable accessories fitted inside the
expansion range of a curtain airbag can dangerously interfere with
its function. A deploying head airbag develops enough force to
catapult any piece of add-on component out of its path of inflation
and into the passenger compartment. An occupant hit by such a projectile can suffer serious injury or death :::::,
page 302, "Tech­
nical Modifications".
• Do not swivel the sun visors to the side if you have any objects
clipped onto them (for example pens). If the airbag should
deploy, you could be injured by these objects. • Use the built-in coat hooks only for lightweight clothing. Never
leave any heavy or sharp-edged objects in the pockets that may
interfere with airbag deployment and can cause per sonal injury in
an accident.
• Never use hangers to hang clothing from the hooks.
• Only use factory-installed sun shades or , in the case of shades
installed after the vehicle leave s the factory, only Audi roll-up
& WARNING (co ntinued )
sunscreens may be used:::::, page 301, "Additional accessories and
parts replacement ".
• Always sit in proper seating position and wear safety belts
while traveling so that the side curtain airbags can help provide
protection.
• The airbag system can only be triggered once . If the airbag has
been triggered, the system must be replaced by an authorized
Audi dealer or qualified workshop.
• Always have work involving the side curtain airbag system,
removal and installation of the airbag components, or other
repairs performed by a qualified workshop. Otherwise the airbag
system may not work correctly.
• Never attempt to modify any components of the airbag system
in any way .•

Child Safety
Important things to know
Introduction
The rear seat is generally the safest place in a collision.
Th e 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 137, "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
of serious injury. Child restraints, like adult sa fety be lts, must be used
pro perl y to be effective. Use d imprope rly, they can i ncrease t he ris k
of serious injury in an accident.
C onsult the ch ild safety seat manufacturer's instruc tion to be s ure
t he seat is right for your child's size
=> page 170, "Importa nt safety
instructions for using ch ild safety seats" . P lease be sure to read and
heed all of the impo rtant informat io n and WAR NIN GS about child
safety, Advanced Airbags, and the insta llation of ch ild rest raints in
t his 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 here . 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 System 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 pos itions 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 in stalled 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 against the backrest, center armrest, or door . •

& WA RNING (conti nued)
• Always install rear-facing child safet y seat s on the rear seat.
• If you must install a rearward facing child safety seat on the
front passenger seat in exceptional circumstances and the
PASSENGER AIR BAG OFF light do es not come on and stay on,
immediately in stall the rear-facing child safety seat in a rea r
seating position and have the airbag system inspected immedi­
ately by your authorized Audi dealer.
& WARNING
If , in exceptional circumstances , you must in stall 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
pa ssenger front and side airbag.
• Always follow the manufacturer 's instructions p rovided with
the child safety seat or carrier.
• 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 install ing the child restra int . The back­
re st must be adju sted to an upright position .
• Always make sure that the PASSENGER AIR BAG OFF light
c omes on and stays on all the time whenever the ignition i s
switched on .•
Advanced front airbag system and children
Your vehicle is equipped with an "Advanced Airbag System" in compli­
ance wi th Uni ted St ates Federa l Mo to r Vehicle Safety St andar d
(FMVSS) 208 as applicable at the time your veh icle was manufac­
tu red . The Advanced A
irbag system in yo ur vehicle has been certif ied to
mee t the "low -r is k" requiremen ts fo r 3-and 6-ye ar old ch ildre n on
t he passenger side and small adults on the dr iver side . The low risk
dep loyment criteria are inten ded to reduce the risk of injury through
interaction with the a irbag t hat can occur, for example, by being too
close to the stee ring wheel an d instr ument panel when the airbag
inflates. In addi tion, the sy stem has been certified to comp ly with t he
"suppression" requirements of the Safety Standa rd, to t urn off the
fron t air bag for infan ts u p to 1 2 months who a re res tra ined on the
front passenger seat in child restrai nts that are listed in the Stan­
d ar d.
Even thoug h your vehicle is equipped with an Advanced Airbag
system , a ll ch ildren, especially those 12 years and yo unger, should
always r ide in t he back seat p roperly restrained for t heir ag e and si ze .
Th e ai rbag on the passenge r si de makes the front seat a potentia lly
dange rous p lace for a child to r ide. Th e front seat is not th e safest
place fo r a child in a forward- facing c hild safety seat. It can be a very
d an ge rous p lace for a n infan t or a large r chil d i n a rea rwa rd-facing
seat. •
Advanced Airbags and the weight-sensing
mat in the front seat
Th e Advanced A irbag System i n your ve hicle de tects t he p resence o f
an infa nt o r ch ild in a child rest rai nt on the fro nt passenger sea t using
the we ight-sens ing mat in the seat cushion and the senso r be low the
saf ety belt la tch o n th e front passenge r seat tha t measur es t he
tension on the safety belt.
Th e weigh t-sens ing ma t me asures tot al we ight of the child and the
child safety seat and a child blanket on the fro nt passe nger seat . The
we ight on the fro nt passenger se at is re late d t o the desi gn of the
child res traint and i ts "footpri nt", the size and shape of t he bottom
of the ch ild restraint as it sits o n the seat . The weight of a child
restrain t an d its "foo tpr int" vary for differe nt kinds of child res tra ints .,_

-----------------------------------------~C~ h~il ~d ~ S~a _!fe ~ t !;YL __
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
child restraints are:

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 everybody
in the vehicle, especially children:
Always use the right child safety seat for each child and
always use it properly~
page 172.
-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 177.
-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 . _,,
