are wearing your safety belt and wearing it properly. This is why you
should always wear your safety belt, not just because the law requires
you to do so:::::,
page 189, "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
being used. Therefore, in a particular collision, it is possible that an
airbag will not deploy at a seat ing position where the safety belt is
being used but will inflate at the position where the safety belt is not
being used.
Remember too, airbags w ill deploy only once and only in certa in kinds
of accidents -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 deployed, for example when your vehicle 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 belt. The airbag system works most effectively when used with
the safety belts . Therefore, always wear your safety belts correctly .
It is important to remember that while the supplemental airbag
system is designed to reduce the likelihood of serious injuries, other
injuries, for example, swelling, bruising, and minor abrasions can
also be associated with airbags.
The knee airbag system basically consists of:
• The electronic control module
• T wo inflatable airbags (airbag and gas generator), one for the
dr iver and one for the front passenger
• The airbag indicator light in the instrument panel
The knee airbag system will not deploy:
• when the ignition is turned off
• in front-end collisions when the deceleration measured by the
control unit is too low
• in s ide collisions •
in rear-end collisions
• in rollovers
• in the event of a system ma lfunction (warning/indicator light illu­
m ina ted):::::,
page 14.
& WARNING
• Safety belts and the airbag system can only provide protection
when occupants are in the proper seating position :::::,
page 208.
• If the airbag indicator light comes 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 deploy the airbag.

& 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~

Side airbags
Description of side airbags
The airbag system can provide supplemental protection
to properly restrained occupants .
Fig. 202 S ide airbag
l o cat ion
in the d rive r's
s e at
The side airbags are located in the sides of the front seat backrests
~ page 218 , fig. 202. They are identified by the word "AIRBAG".
The side airbag sy stem basicall y consists of :
• the electronic control module and external s ide impact sensors
• t he two side airbags located in t he sides o f the front backrests
• the airbag warning light in the instrument cluster.
T he airbag sys tem is moni tore d ele ct ronically to make certa in that it
is funct ioning properly at all times. Each time you turn on the igni­
t ion , the airbag system indicator light w ill come o n for a few seconds
(self diagnostics) .
The side airbag system supp lements the safety belts and can he lp to
red uce the risk of injury to the drive r's an d front passenge r's upper
torso on the s ide of the vehicle that is struck in a side collision . The
a irbag dep loys o nly in side impac ts an d only when the veh icle acceler ­
ation registered by the contro l unit is h igh eno ugh. If this rate is
below the refe rence val ue p rogrammed into the control u nit, t he side
airbags will not be triggered, eve n thoug h the car may be badly damaged as a resu
lt of the collision. It is not possib le to define an
air bag trigger ing range tha t w ill cove r eve ry poss ible an gle o f imp act,
since the circumsta nces will vary considerab ly between one collision
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 219, "Important safety instructions on the side
airbag system" .
Aside from the ir normal safety function, safety be lts work to he lp
keep the driver or fron t passenger in po sit io n in t he event of a side
collision so that the side airbags ca n provide p rotect ion.
T he a irbag system is
not a substitute for your safety be lt. Rather, it is
pa rt of the ove rall occupant res trai nt system in your veh icle. Always
remember that the side airbag system can only help to protect you if
you a re wear ing yo ur safety belt and wea ring it properly. This is
another reason why you shou ld always wear your safety belts, not just
bec ause t he law requires you to do so~
page 189, '' Genera l no tes ".
It is important to remember that while the supp lemental s ide airbag
system is designed to red uce the lik elihood o f serious injuries, other
injuries, fo r example, swe lli ng, br uis ing , and minor abras io ns can
also be assoc iated w ith deployed side airbags. Remember too, side
airbags will de ploy only once and only in cert ain kinds of acc idents -
your safety belts are a lways there to offer protection.
Vehicle dam age, re pair costs o r even the la ck of vehicle dam age are
not necessarily an ind ication of over-sensitive or failed airbag activa­
t ion. In some collisions, both front and side airbags may infla te .
Remember too , tha t airbags will de ploy only once and only in certa in
kinds of collisions -yo ur sa fety bel ts are a lways the re to offe r protec ­
tion i n those accide nts in which airbags ar e not s upposed to deploy o r
when they have already dep loyed.
The side airbag system will not deploy:
• when the ign ition is turned off
• in side co llisi ons when the accelerat ion measured by the sensor is
t oo low
• in front -end col lisions ._

• 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. •

& WARNING (continued)
- 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.
- 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
cupholders, 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 prevent the side airbags from being damaged by heavy
objects knocking against or hitting the sides of the seatbacks.
& WARNING (co ntinued )
• 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 221, "Child Safety ".
• Never attempt to modify any components of the airbag system
in any way.
• In a side collision, side airbags will not function properly if
sensors cannot correctly measure increasing air pressure inside
the doors when air escapes through larger, unclosed openings in
the door panel.
- Never drive with interior door trim panels removed.
-Never drive when parts have been removed from the inside
door panel and the openings they leave have not been properly
closed.
- Never drive when loudspeakers in the doors have been removed unless the speaker holes have been properly closed.
- Always make certain that openings are covered or filled if
additional speakers or other equipment is installed in the
inside door panels.
- Always have work on the doors done by an authorized Audi
dealer or qualified workshop . •

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

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. •

Advanced front airbag system and children
Your vehicle is equi pped wi th a fron t "Advanced Airbag System" in
compliance with United States Federal Motor Vehicle Safety Standard
( F MVSS) 2 08 as appli ca ble at t he time your ve hicle was manufa c­
tured. 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 system 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 up to 1 2 months who a re res train ed 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
