when they are correctly positioned on the body.
Improper seating positions reduce the effective
ness of safety belts and will even increase the
risk of injury and death by moving the safety belt
to cr it ica l areas of the body . Improper seating
positions also increase the risk of serious injury
and death when an airbag deploys and strikes an
occupant who is not in the correct seating posi
tion. A driver is responsible for the safety of all
vehicle occupants and especia lly for children.
Therefore:
... Never permit anyone to assume an incorrect
sitting position in the vehicle whi le traveling

Belt tensioners
' How safety belt pretensioners work
In front, side and rear-end collisions above a
particular severity and in a rollover, safety belts
are tensioned automatically.
Rever sible safety belt tensioners
The safety belts on the front seats are equipped
with power reversible tensioners. The following
functions are available when the driver's/front
passenger 's safety belts are fastened:
- Automatic tensioners: at the start of a drive,
the safety belts automatically adjust to the
passenger after a certain time period or vehicle
speed. To switch the automatic tensioners off,
select the following in the MMI:
!CARI function
button
> Car systems > Vehicle settings >
Seats > Driver's seat or Passenger's seat > Au
tomatic belt tensioner
> Off.
-In certa in driving situations , the safety belts
may tighten with a reve rsib le tensioning func
tion
c:> page 187.
- Th e safety be lts may also tighten with this re-
vers ible tensioning funct ion in minor collisions.
Pyrotechnic safety belt pretensioners
The safety belts are equipped w ith safety belt
pretensioners . The system is activated by sensors
i n front, side and rear-end collisions of great se
verity and in a rollover. This tightens the belt and
takes up belt slack
c:> .&. in Service and disposal of
safety belt pretensioner on page 145.
Taking up
the slack helps to reduce forward occupant
movement during a collision.
A WARNING
- It is possible for the pretensioners to deploy
incorrectly.
- The pyrotechnic system can only provide protection for one collision. If the pyrotech
nic pretens ioners deploy, the pretensioning
system must be replaced.
(1) Tips
The pyrotechnic safety belt pretensioners can
only deploy once. ..,_
Page 147 of 302

-The safety belt pretensioners do not dep loy
in minor fronta l, side and rear -end co lli
s ions .
- A fine dust is released when the pyrotechnic
safety belt pretensioners deploy. This is nor
mal and is not caused by a fire in the vehi
cle.
- The relevant safety requirements must be
observed when the veh icle or components
of the system are scrapped. A qualified
dealersh ip is familiar w ith these regulations
and will be pleased to pass on the informa
tion to you .
- Be sure to observe all safety, environmental
and other regu lations if the veh icle or indi
v idual parts of the system, particularly the
safety be lt o r airbag, a re to be disposed . We
recommend yo u have your author ized Audi
dealer perform this serv ice for you.
Service and disposal of safety belt preten
sioner
The safety belt pretens ioners are parts of the
safety belts on your Audi. Insta lling, removing,
servic ing or repa iring of belt p retensioners can
damage the safety belt system and prevent it
from wor king cor rect ly in a collision .
T here are some important things you have to
know to make sure that the effectiveness of the
sys tem w ill not be impaired and that discarded
components do not cause injury or pollute the
e nvironment.
_& WARNING
-
Improper care, serv icing and repa ir proce
dures can increase the risk o f personal injury
and death by preventing a safety be lt preten
sioner from activating when needed or acti
vating it unexpectedly :
- The be lt pretensioner system can be activat
ed only once . If belt pretensioners have
been activated, the system must be re
placed .
- Never repair, adjust, or change any parts of
the safety belt system.
- Safety belt systems including safety belt
pretens ioners cannot be repaired. Specia l

Airbag syste m
Airbag system
Important information
Importance of wearing safety belts and
sitting properly
Airbags are only supplemental restraints . For
airbags to do their job, occupants must always
properly wear their safety belts and be in a prop
er seating position.
For your safety and the safety of your passen
ge rs , before driving off, always :
"' Adjust the driver's seat and steering wheel
properly ¢
page 130,
"'Adjust the front passenge r's seat properly
¢ page 59,
"'Wear safety belts p roperly ¢ page 140,
"'Always properly use the proper child restraint
to protect children
¢ page 168.
In a coll is io n, airbags mus t inflate within the
blink of an eye and wi th considerab le force. The
supp lemental airbags can cause injuries if the
driv er or th e front s eat passeng er is not s eated
properly. Therefore in order to he lp the airbag to
do its job, it is important, both as a dr iver and as
a passenger to sit properly at all t imes.
By keeping room between your body and the
steering whee l and the front of the passenger
compartment, the a irbag can inflate fully and
completely and provide supplemental protect ion
in certain frontal collisions¢
page 130, Correct
passenger seating positions .
For details on the
operation of the seat adjustment con trols
¢ page 59.
It's especially important that children are proper
ly restra ined
¢ page 168 .
There is a lot that the driver and the passengers
can and must do to help the ind iv idual safety fea
tures installed in your Audi work together as a
system .
Proper seating posit ion is important so that the
front airbag on the drive r side can do its job. If
you have a physical impairment or cond ition that
prevents you from s itting properly on the driver
seat with the safety be lt properly fastened and
146
reaching the peda ls, or if yo u have concerns w ith
regard to the function or operation of the Ad
vanced Airbag System, please contact your a u
thori zed Audi dea ler or qua lified workshop, or
ca ll Audi Customer Relations at 1-800-822-2834
for poss ib le modifications to your vehicle .
When the airbag system dep loys, a gas generator
will fill the airbags, break open the padded cov ers, and infla te between the steering wheel and
the driver and between the instrument panel and
t h e front passenger . The airbags w il l deflate im
med iate ly after deployment so that the front oc
cupants can see t hrou gh the windsh ie ld again
without i nterruption.
All of th is takes p lace in the b link of an eye, so
fast that many people don't even rea lize that the
a irbags have deployed. The airbags a lso infla te
with a g re at deal of force and nothing should be
i n the ir way when they deploy. Front airbags in
combination with properly worn safety belts slow
down and limit the occupant 's forward move
ment . Together they he lp to prevent the driver
and front seat passenger from hitting pa rts of
the ins ide of the vehicle while reduc ing the fo rces
acting on the occupant dur ing the cras h. In th is
way they help to reduce the risk of injury to the
head and uppe r body i n the crash . Airbags do not
protect the arms or the lower pa rts of the body.
Both front airbags will not inflate in all frontal
collisions . The t riggering of the a irbag system de
pends on the veh icle decelerat ion rate caused by
t h e coll is io n and regis tered by the ele ctroni c con
tro l unit . If this ra te is be low the refe rence value
programmed in to the contro l unit, the airbags
will not be trigge red, even tho ugh the car may be
badly damaged as a resu lt of the collision. Vehi
cle damage, rep air costs or even the lack of vehi
cle damage is not necessarily an indication of
whether an a irbag should inflate or not .
Since the circumstances will vary cons iderab ly
between one co llision and another, it is not possi
ble to define a range of veh icle speeds that will
cover every poss ible kind and angle of impact
that w ill always t rigger t he a irbags . Important
factors i nclude, for examp le, the nat ure (hard or
soft) of the object which the ca r hits, the angle of
i mp act , vehicle speed , etc. The front airbags will .,.
Page 149 of 302

also not inflate in side or rear collisions, or in
ro ll-overs.
A lwa ys rememb er: Airbags will deploy only o nce,
and on ly in certain kinds of coll is ions. Your safety
be lts are always there to offer protection in those
situations in which airbags are not supposed to
deploy, or when they have a lready deployed; for
examp le, when your vehicle str ikes or is struck by
another vehicle after the first collis ion.
This is just one of the reasons why an airbag is a
supp lementary restraint and is not a substitute
for a safety belt. The airbag system works most effect ively when used with the safety belts.
Therefore, always properly wear your safety belts
c::>page 138.
A WARNING
Sitting too close to the steer ing whee l or in
st rument panel will decrease the effect ive
ness of the airbags and will inc rease the risk
o f persona l injury in a co llision.
- Never sit closer than 10 inches (25 cm) to
the steering wheel or instrument panel.
- If you cannot sit mo re than 10 inches
( 2 5 cm) from the steering wheel, inves ti
gate whethe r adaptive equipment may be
available to help you reach the pedals and
increase your seating distance from the
steering wheel.
- If you are unrest rained, leaning forward, s it
ting s ideways or out of position in any way,
your risk of in jury is much h igher.
- Yo u will also receive serious injur ies and
cou ld even be killed if you are up against the
airbag or too close to it when it inf lates -
even with an Advanced Airbag.
- To reduce the risk of in jury when an airbag
inflates, a lways wear safety belts p roperly
i=> page 141, Safety belts .
-Always make certain that ch ild ren age 12 or
younger always ride in the rear seat. If chil dren are not properly restra ined, they may
be severe ly injured o r kill ed when an airbag
inflates .
- Never let children ride unrestrained or im prope rly restrained in the veh icle. Adjust the
fro nt sea ts properly.
-
Airb ag sys tem
-Never ride with the back rest recl ined.
-Always sit as fa r as possible from the steer-
ing wheel o r the instrument panel
c::> page 130.
- Always sit upright with your back against
the backrest of your seat.
- Never p lace your feet on the instrument
panel or on the seat. Always keep both feet
on the floor in front of the seat to help pre
vent ser ious injuries to the legs and hips if
the airbag inflates.
- Never recline the front passenger's seat to transpo rt objects. Items can also move into
the area of the s ide a irbag or the front air
bag during braking or in a sudden maneu
ver. Objects nea r the airbags can become
p roje ct il es and cause injury when an airbag
inflates.
A WARNING
A irbags tha t h ave deployed in a cr ash m ust be

There is a lot you need to know about the airbags
in your vehicle . We urge you to read the detai led
i nformation about airbags, safety belts and ch ild
safety in this and the other chapters that make
up the owner's literature. Please be sure to heed
the WARNINGS -they are extremely important
for your safety and the safety of your passengers,
especially infants and small children .
.&_ WARNING -
Never rely on airbags alone for protection.
- Even when they deploy, airbags provide only
supp lemental protection.
- Airbag work most effectively when used
with properly worn safety belts .
- Therefore, always wear your safety belts and make sure that everybody in your vehicle is
properly restrained .
.&_ WARNING
A person on the front passenger seat, espe
cially infants and small ch ildren, wi ll receive
serious injuries and can even be killed by be
ing too close to the airbag when it inf lates.
- Although the Advanced Airbag System in
-
your vehicle is designed to turn off the front
passenger airbag if an infant or a small child
is on the front passenger seat, nobody can
absolutely guarantee that deployment un
der these special conditions is impossible in
all conceivable situations that may happen
during the useful life of your vehicle.
- The Advanced Airbag System can deploy in
accordance with the "low risk" option under
the U.S. Federal Standard if a child that is
heav ier than the typical one-year old ch ild is
on the front passenger seat and the other
conditions for airbag deployment are met.
- Accident statistics have shown that children
are generally safer in the rear seat area than
in the front seating pos ition.
- For their own safety, all children, especially
12 years and younger, should always ride in
the back properly restrained for their age
and size.

Advanced front airbag system
Your vehicle is equipped with a front Advanced
Airbag System in compliance with Un ited States
F edera l Motor Vehicle Safety Standard 208, as
well as Canada Motor Vehicle Safety Standard
(CMVSS) 208 as applicable at the time your vehi
cle was manufactured .
The front Advanced Airbag System supp lements
the safety belts to provide additional protection
for the driver's and front passenger's heads and upper bodies in frontal crashes . The airbags in
f late only in frontal impacts when the veh icle de
celeration is high enough.
The front Advanced Airbag System for the front
seat occupants is not a substitute for your safety be lts . Rather, it is part of the overall occupant re
stra int system in your vehicle. Always remember
that the airbag system can on ly help to protect
you, if you are sitting upr ight, wear ing your safe
ty belt and wear ing it prope rly. This is why you
and your passengers must always be prope rly re
stra ined, not just beca use the law req uires yo u to
be .
The Advanced Airbag System in your veh icle has
been ce rtified to meet the "low r is k" requi re
ments fo r 3 and 6 ye ar-old children o n the pas
senger side and very sma ll adults on the drive r
side . The low risk dep loyment criteria are intend
ed to help reduce the risk of injury through inter
action with the front a irbag that can occur, for
examp le, by being too close to the steering wheel
and instrument panel when the airbag inflates .
In addition, the system has been certified to
comp ly with the "suppression" requirements of
the Safety Standard, to turn off the front a irbag
for i nfants 12 months old and younger who are
restrained on the front passenger seat in child re
stra ints that are listed in the Standa rd
¢ page 170, Child restraints and Advanced Air
bags.
"Suppress ion" requ ires the front a irbag on the
passenger side to be turned off if:
- a ch ild up to about one year of age is restra ined
on the front passenger seat in one of the rear
facing or forward-fac ing infant restra ints listed
Airb ag sys tem
in Federal Motor Veh icle Safety Standard 208
with which the Advanced Airbag System in your
veh icle was certif ied. For a List ing of the child
restraints that were used to certify your vehi
cle's compliance with the US Safety Standard
¢page 170,
-weight less than a threshold level stored in the
control un it is detected on the front passenger
seat .
When a person is detected on the front passen ger seat, weighing more than the total weight of
a chi ld that is about
1 year old restra ined in one
of the rear-facing or forward-fac ing infant re
straints (listed in Federal Motor Veh icle Safety
Standard 208 with w hich the Advanced A irbag
System in your veh icle was certified), the front
airbag on the passenge r side may o r may not de

whe n the elect ronic control uni t detects a tota l
weight on the fron t passenger sea t th at req uires
the front a irbag to be turned off . If the
PASSEN
GER AIR BAG OFF
light does not come on, the
front airbag on the passenger side has not been
turned off by the control unit and can dep loy if
the control unit senses an impact that meets the
condit ions stored in its memory .
If the total weight on the front passenger seat is
more than that of a typica l 1 year-old, but less
than the weight of a small adult, the front airbag
o n the passenger s ide may deploy (the
PAS SEN

For example , the ai rb ag may deploy if :
- a small chi ld that is heav ier than a typ ica l 1
yea r-o ld child is on the front passenger seat
(regard less of whether the child is in one of the
child seats listed
¢ page 170),
- a child who has outgrown c hild restraints is on
