Safety belts are important to help keep front
seat occupants in the proper seated position so
that airbags can unfold properly and provide sup­ p lemental protection in a frontal collision.
The front airbags are designed to provide addi­
tional protect ion 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
oc-
cupant is properly seated as far as possible
from the airbag
- and the head restraints have been properly ad-
justed
Because airbags inflate in the blink of an eye w ith
great force, things you have on your lap or have p laced on the seat could become dangerous pro­
jectiles, and be pushed into you if the airbag in­ flates .
When an airbag deploys, fine dust is released.
This is normal and is not caused by a fire in the
veh icle. This dust is made up mostly of a powder
used to lubricate the airbags as they deploy . It
could irr itate skin .
It is important to remember that while the sup­ plemental airbag system is designed to reduce
the likelihood of ser ious injuries, other injuries,
for example swelling, bruising and minor abra-
Airb ag sys tem
sions, can also happen when airbags inflate. Air­
bags do not protect the arms or the lower parts
of the body. Front airbags supp lement the three­
point safety belts only in some frontal collisions
in which the vehicle dece leration is high enough
to deploy the airbags .
Front airbags will not depl oy :
- if the ignition is switched off when a crash oc-
curs
- in side co llisions
- in rear-end coll isions
- in rollovers
- when the crash deceleration measured by the
ai rbag system is less than the m inimum thresh­
old needed for airbag dep loyment as registe red
by the electronic control un it
The front pass enge r airbag also w ill not
deploy:
- when the fron t passenger seat is not occupied,
- when the e lectr ical capacitance measured by
t he capacit ive passenger detection system for
the front passenge r seat ind icates that the pas­
senger side frontal airbag m ust be switched off
by the electronic control unit (the

_& WARNING
Sitting in the wrong position can increase the
risk of ser ious injury in crashes.
- To reduce the risk of injury when the a irbags
inflate, the driver and passengers must al­
ways sit in an upright posit ion, must not
lean aga inst or place any part of their body
too close to the area where the airbags are lo cated.
- Occupants who are unbelted, out of posit ion
or too close to the airbag can be serio usly
inj ured by an airbag as it unfolds wi th g reat

seat after taking the steps described above,
make sure the adu lt is properly seated and
restrained at one of the rear seating posi­
tions . Have the a irbag system inspected by
your author ized Audi dealer before trans­
port ing anyone on the front passenger seat.
A WARNING
f-
An a irbag system that is not functioning prop-
e rly cannot prov ide supplemental protect io n
i n a front al crash.
- I f the ai rbag ind icator light
~page 32
comes when the veh icle is being used, have
the system inspected immedia tely by your
authorized Audi dealer . It is possib le that
the airbag will inflate when it is not sup­
posed to, or will not inflate when it should.
A WARNING
If the front airbag inflates, a ch ild without a
chi ld restraint, or in a rearward-facing child
safety seat, or in a forward-fac ing child re­
stra int that has not been properly insta lled
will be seriously injured and can be killed.
- Even though your vehicle is equipped with
an Advanced A irbag System, make certain
that all children , espec ially 12 years and
younge r, always ride on the back seat p rop­
erly rest rained for the ir age and s ize .
- Always install fo rwa rd or rear-facing child
safety seats on the rear seat - even with an
Advan ced Airbag System.
- I f you must install a rea rwa rd-facing child
safety seat on the front passenger seat be­
cause of excep tional circums tances and the
PASSENGER AIR BAG OFF ,;, light does not
appear and stay on, immediate ly install the
rear-facing chi ld safety seat in a rear seat ing
position and have the a irbag system in­
spected by your authori zed Aud i dea ler.
- If, in exceptional circumstances, you must
install a forward-facing child restraint on
the front passenger seat, always move the seat into its rearmost position in the seat's
fore and aft ad justment range, as far away
from the a irbag as poss ible . The back rest
m ust be adjusted to an upr ight position .

All of this takes place in the blink of an eye, so
fast that many people don't even realize that the airbags have deployed . The airbags also inflate
with a great deal of force and it is important for
occupant safety that nothing should be in their
way when they deploy .
Fully inflated airbags in comb ination with proper­
ly worn safety belts slow down and limit the oc­
cupant 's forward movement and help to reduce
the r isk of injury .
Important safety instructions on the knee
airbag system
Airbags are only supplemental restraints . Always
wear safety belts correctly and ride in a proper
seating position.
There is a lot that you and your passengers must
know and do to help the safety be lts and airbags
to provide s upplemental protection .
,& WARNING
An inflating knee airbag can cause ser ious in­
jury. Wearing safety bel ts incor rectly and im­
proper seating posit ions increase the r isk o f
serious personal injury and death whenever a
vehicle is being used.
- The knee airbag system cannot protect you
prope rly if you are seated too close to any of
the a irbag locat ions. When ad justing their
seat positions, it is important that both the
dr iver and the front passenger keep their
upper bod ies a nd knees at the following
min imum safe d istances:
- at least 10 inches (25 cm) between the
chest and the steering wheel/instrument
panel.
- at least 4 inc hes (10 cm) between the
knees and the lower part of the instru­
ment panel.
- The risk of persona l injury increases if you
lean forward or to the side, or if the seat is
improper ly positioned and you are not wear­
ing your safety belt. The risk increases even
more should the a irbag deploy.
- Always make sure that the knee airbag can
inflate without interference. Objects
be-
Airb ag sys tem
tween you and the airbag can increase the
risk of injury in an accident by interfering
wit h the way the airbag deploys or by being
pushed into yo u as the a irbag deploys.
- Never let anybo dy, especi ally children or
anima ls r ide in the footwell i n front of the
passenger seat. If the airbag deploys, this
can result in serious o r fatal in juries.
- Never carry objects of any kind in the foo t­
well area in front of the driver's or pas­
senger's seat . Bulky objects (shopp ing
bags, for example) can interfere with or
prevent proper dep loyment of the airbag.
Small objects can be thrown th rough t he
vehicle if the airbag deploys and injure you
o r your passengers.
- Make sure the re a re no cracks, deep scratch­
es o r othe r damage in the area of the inst ru­
ment panel where the knee airbags a re lo­
ca ted.
- If ch ildren are incorrectly seated, their risk
of injury inc reases in a coll is ion

protection to properly restrained occupants.
Fi g. 2 44 Side a irbag locat ion in the drive r's sea t
The side airbags are located in the s ides of the
front seat
backrests ~ fig. 244 and the rear back­
res t* facing the doo rs.
The side airbags installed for the front seating
pos itions have been des igned and certified to
help reduce the risk of in ju ry that can be caused
by a irbags when they inflate, pa rticul arly when

Airbag system
the occupant sitting next to it is not seated prop­
erly. The side airbag for the front passenger seat
can be used with properly installed child re­
straints. Please be sure to read the important in­
formation and warnings whenever using a child
restraint in a vehicle: Safety belts
Qpage 263,
Airbag system Qpage 271, Ch ild safety
c::;, page 295.
The side airbag system basically consists of:
-the e lectronic control modu le and externa l side
impact sensors
- the two side airbags located in the sides of the
front backrests
- two rear side airbags*
- the airbag warning light in the inst rument clus -
ter.
The airbag system is monitored electronically to make certa in that it is functioning properly at all
times. Each time you turn on the ign it ion, the air­
bag system indicator light will come on for a few
seconds (self diagnostics).
The side airbag system supplements the safety
be lts and can help to reduce the risk of injury to
the driver's, front and rear* passenger 's upper
torso on the side of the vehicle that is struck in a
side co llision. The a irbag dep loys only in side im­
pacts and on ly when the vehicle acceleration reg­
istered by the control unit is high enough . If this
rate is below the reference value programmed in­
to the control un it, the side airbags will not be
tr iggered, even though the car may be badly
damaged as a result of the collision.
It is not pos­
sib le to define an a irbag tr igger ing range that
will cover every possible angle of impact, since
the circumstances will vary considerably between
one collision and another . Important factors in­
clude, for example, the nature (hard or soft) of
the impacting object, the angle of impact, vehicle
speed, etc.
Q page 291, Important safety in­
structions on the side airbag system.
Aside from their normal safety function, safety be lts work to help keep the driver or front pas­
senger in pos it ion in the event of a s ide collision
so that the side a irbags can provide protection.
The airbag system is
not a subst itute for your
safety belt. Rather, it is part of the overall occu-
290
pant res traint system in your vehicle . Always re­
member that the side airbag system can only
help to protect you if you are wear ing your safety
belt and wearing it properly. This is another rea­
son why you should a lways wear your safety
belts, not just because the law requires you to do
soc::;, page 263, General information .
It is important to remember that while the sup­
plemental side airbag system is designed to re­
duce the likelihood of ser ious injuries, other inju­
ries, for example, swelling, bru is ing, friction
burns and minor abrasions can also be assoc iated
with deployed side airbags. Remember too, side
a irbags w ill dep loy only once and only in certa in
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 necessarily an ind icat ion
of over-sens itive or fa iled airbag activation. In
some collisions, both front and side airbags may
inflate. Remember too, that airbags wi ll deploy
on ly once and only in certain kinds of collisions
-
your safety be lts are always there to offer protec­
tion in those accidents in which airbags are not
supposed to deploy or when they have already
deployed .
The side airbag system will not deploy:
- when the ignition is turned off
- in side co llisions when the acceleration meas -
ured by the sensor is too low
- in front-end collisions
- in rea r-end collisions
- in rollovers.
In some types of accidents the front airbags, side
curta in airbags and side a irbags may be triggered
together .
&_ WARNING
-Safety belts and the airbag system will only
provide protection when occupants are in
the proper seating position
Q page 291.
- If the airbag indicato r light Q page 32
comes when the vehicle is being used, have
the system inspected immediately by your
authorized Audi dealer. It is possible that

the airbag will inflate when it is not
supposed
to, or will not inflate when it
should.
How supplemental side airbags work
Side airbags deploy instantly and can help re­ duce the risk of upper torso injuries for occu­
pants who are properly restrained.
Fig. 245 Infla ted side airbags on left side of veh icle, rear
side airbag opt ional equipment
When the system is triggered, the airbag is filled
with propellant gas and breaks through a seam in
the seat surface area.
It expands between the
side trim panel and the passenger. In order to
help provide this additional protection, the side
airbag must inflate within a fraction of a second
at very high speed and with great force . The sup­
plemental side airbag could injure you if your
seating position is not proper or upright or if
items are locat ed in the area where the supple­
mental side airbag expands. This applies espe­
cially to
children¢ page 295, Child safety. Sup­
plemental side airbags inf late between the occu­
pant and the door panel on the side of the vehicle
that is struck in certain side
collision ¢ fig. 245.
Although they are not a soft pillow, they can
"cushion" the impact and in this way they can
help to reduce the risk of injury to the upper part
of the body.
A fine dust may develop when the airbag deploys.
This is normal and does not mean there is a fire
in the vehicle .

A WARNING
An inflating side airbag can cause serious or
fatal injury. Improperly 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 supple­
mental 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 de­ ploy.
- 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 in­
crease the risk of injury in an accident by in­
terfering with the way the airbag unfolds or

- Only use factory-installed s un shades or, if
shades installed after the veh icle leaves the
factory, use only genuine Aud i sun shades.
- Never swing the sun viso rs ove r to the side
windows if things such as pens, ga rage door
openers, hands-free speakers, etc . are at­
tached to the sun visors. They co uld come
294
loose and cause serious injury if the side cu r­
tain airbag inflates.
- A deploying airbag inflates in a fraction of a
second and with great force.
- Never attach objects to the cover or in the
deployment zone of a side curtain airbag .
- The a irbag deployment zones must be kept
clear at all times. Make s ure there are no
objects, pets, o r other persons in the space
between any vehicle occupant and any air­
bag at any time.
- Do not attach any accessories to the doors.
A WARNING
- The a irbag system can deploy on ly once. If
the airbag has been triggered, the system
m ust be rep laced by an authorized A udi
dealer or qualified workshop .
- Always have work invo lv ing the side curtain
airbag system, remova l and installat ion of
the airbag components, or other repairs
pe rformed by a q ualified dealership. Other­

Child safety
Important information
Introduction
The rear seat is generally the safest place in a
collision .
The physical principles of what happens when
your vehicle is in a crash apply also to children
c:> page 264, What happens to occupants not
wearing safety belts? .
But unlike adults and
teenagers, their muscles and bones are not fully
developed. In many respects children are at
greater r isk of serious injury in crashes than
adults .
Because children's bodies are not fu lly devel­
oped, they require restraint systems especially
designed for their size, weight, and body struc­
ture. Many countries and all states of the United
States and provinces of Canada have laws requir­
ing the use of approved child restraint systems
for infants and small children .
I n a frontal crash at a speed of 20 -35 mph (30 -
56 km/h) the forces acting on a 13-pound (6 kg)
infant will be more than 20 times the weight of
the child . This means the weight of the chi ld
would suddenly be more than 260 pounds (120 kg) . Under these conditions, only an appro­
priate child restraint properly used can reduce
the r isk of serious injury . Child restra ints, like
adult safety belts, must be used properly to be
effect ive. Used improperly, they can inc rease the
risk of serious injury in an accident.
All ch ildren, especially those 12 years and young­
er must always ride in the back seat proper ly re­
stra ined for their age and size. If you must install
a child restraint on the front passenger seat in
exceptional circumstances, be sure to read and
heed the important information and warnings
c:> page 2 72. Infants and other children who are
properly restrained in an appropriate child re­
straint that is for their size and age can benefit
from the protection that supplemental side air­
bags provide in some kinds of crashes.

(NHTSA), currently at: http:/ /www.safe ­
rcar.gov (for the USA)
- Transport Canada Information Centre, current-

Consult the child safety seat manufacturer's in­
structions in order to be sure the seat is right for
yo ur child's size
c:> page 299, Important safety
instructions for using child safety seats .
Please
be sure to read and heed all of the important in­
formation and WARNINGS about child safety,
Advanced Airbags, and the installation of child
restra ints in this chapter .
There is a lot you need to know about the Ad­
vanced Airbags in your vehicle and how they work
when infants and children in child restraints are on the front passenger seat . Because of the large
amount of important informat ion, we cannot re­
peat it all he re. We urge you to read the detailed
information in this owner 's manual about airbags
and the Advanced Airbag Sys tem in yo ur vehicle
and the very important information about trans­
porting children on the front passenger seat.
P lease be sure to heed the WARNINGS -they are
extremely important for your safety and the safe­
ty of your passengers, especially infants and
small children.
A WARNING
-- Accident statistics have shown that children
are generally safer in the rear seat area than
in the front seat ing pos ition. Always restrain
any child age 12 and under in the rear.
- All vehicle occupants and especially children
must be restrained properly whenever riding
in a vehicle. An unrestrained or imp roperly
rest rained child could be injured by striking
the interior or by being ejected from the ve­ hicle during a sudden maneuver or impact.
An unrestrained or improperly restrained
child is also at greater r isk of injury or death
through contact w ith an inflating a irbag.
-A suitable ch ild restraint properly installed
and used at one of the rear seating positions
provides the h ighest degree of protect ion
for infants and small children in most acci­
dent situat ions.
