Safe ty belts
Autom ati c s afet y belt retr actors
Every safety belt is equ ipped with an automa tic
be lt retractor on the shoulder belt. This feature
locks the belt when the belt is pulled out fast,
during hard braking and in a n accident . The belt
may a lso lock when you drive up or down a steep
hill or through a sharp curve. Dur ing normal driv
ing the belt lets you
move freely .
Safety belt p ret en sion ers
The safety belts are equipped with a belt preten
sioner that helps to t ighten the safety belt and
remove slack when the pretensioner is activated.
The function of the pretensioner is mon itored by
a warning light
r:::') page 19.
Convertib le loc king retracto r
Every safety be lt except the one on the driver
seat is equipped with a convertible locking retrac
tor that
mus t be used when the safety belt is
used to attach a child safety seat. Be sure to read
the impo rtant information about this feature

Safety belt position.
- Safety belts offer optimum protection only
when the seatback is upright and belts are
properly positioned on the body.
- Always make sure that the rear seat back
rest to which the center rea r safety belt is
attached is secure ly latched whenever the
rear center safety belt is being used. If the
backrest is not securely latched, the passen
ger will move forward with the backrest dur
ing sudden braking, in a sudden maneuver
and especially in a crash.
- Never attach the safety belt to the buckle for another seat. Attaching the belt to the
wrong buckle will reduce safety belt effec
tiveness and can cause serious persona l in
jury.
- A passenger who is not properly restrained can be seriously in jured by the safety be lt it
self when it moves from the stronger parts
134
of the body into critical areas like the abdo men.
- Always lock the convertible locking retractor
when you are securing a child safety seat in

Improperly worn safety belts
Incorrectly positioned safety belts can cause se
vere injuries.
Wearing safety belts improperly can cause seri
ous injury or death. Safety belts can only work
when they are correctly positioned on the body.
Improper seating positions reduce the effect ive
ness of safety belts and will even inc rease the
risk of injury and death by mov ing the safety belt
to cr it ica l areas of the body. Improper seating
positions a lso increase the risk of serious injury
and death when an airbag deploys and strikes an
occupant who is not in the correct seating pos i
tion. A driver is responsible for the safety of all
veh icle occupants and especially for children.
Therefore:
"' Never permit anyone to assume an incorrect
sitting position in the vehicle while traveling

A WARNING
Improperly worn safety belts increase the risk
of serious personal injury and death whenever
a vehicle is being used.

Belt tensioners
How safety belt pretensioners work
In front, side and rear-end collisions above a
particular severity, safety belts ore tensioned au tomatically.
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 . This t igh tens the belt and takes up belt
s lack
c::> & in Service and disposal of safety belt
pretensioner on page 137.
Tak ing up the s lack
helps to reduce forward occupant movement dur
ing a collis ion.
(D Note
Never let the belt remain over a rear seatback
that has been folded forward .
@ Tips
The safety belt pretensioner can only be acti
vated once.
- Th e safety belt pretensioners do not deploy
in minor frontal, side and rear-end colli
sions.
- In the case of a side crash, the safety belt
pretensioners will activate on the driver's or
front passenger's sides only, depending on
wh ich side of the vehicle the crash occurs.
- When the safety belt pretensioners are acti
vated, a fine dust is released. This is normal
and is not caused by a fire in the vehicle.
- The relevant safety requirements must be
observed when the vehicle or components
of the system are scrapped. An authorized
Audi dealer or qualified workshop is familiar
with these regulations and will be pleased
to pass on the information to you. .,_

Service and disposal of safety belt preten
sioner
The safety belt pretens ione rs are parts of the
safety be lts on yo ur Audi. Installing, removing,
servicing or repairing of belt pretensioners can
damage the safety belt system and prevent it
from work ing correctly in a collision .
There are some important things you have to
know to make sure that the effectiveness of the
system wi ll not be impaired and that discarded
components do not cause injury or poll ute the
environment.
A WARNING
Improper care, serv icing and repa ir proce
dures can increase the r isk of personal injury
and death by preventing a safety be lt preten
sioner from activating when needed or acti
vating i t unexpectedly:
- The be lt pretensione r system can be act ivat
ed only once.
If belt pretensione rs have
been ac tiva ted, the system must be re
placed.
- Never repair, adjust, or change any parts of
the s afety be lt system.
- Safe ty bel t systems in cl ud ing safe ty belt
pretens ioners cannot be repaired. Specia l
procedu res are req uired for removal, insta l
lat ion and disposa l of this system.
- For any wor k on the safety belt system, we
strongly recommend that you see your au

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 122,
"'Adjust the front passenge r's seat properly
¢ page 60,
"'Wear safety belts p roperly ¢ page 132 ,
"'Always properly use the proper child restraint
to protect children
¢ page 158.
In a coll is io n airbags must inflate wi thin the b link
of an eye and with cons iderable force . The sup
p lemental airbags can cause injuries if the driver
or the front seat passenger is not s eated proper ·
Ly. T herefore in order to help the airbag to do its
job, it is important, both as a dr iver and as a pas
senger 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 122, Correct
passenger seating positions .
For details on the
operation of the seat adjustment con trols
¢ page 60.
It's especially important that children are proper
ly restra ined
¢ page 158 .
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
138
reaching the peda ls, special modifications to
your vehicle may be necessary.
Contact yo ur aut ho rized Aud i dea le r, or call A udi
C u stomer Rela tions a t 1-800-822-2834.
When the airbag sys tem dep loys, a gas generator
will fill the a irbags, b reak open the padded cov
e rs, and inflate betwee n the steering wheel and
the driver and between the inst rument pa nel and
the front passenger . The a irbags w ill deflate im
mediate ly after dep loyment so t hat the front oc
cupants can see th ro u gh the windsh ie ld again
without interruption.
A ll of th is takes p lace in the blink of an eye, so
fast that many people don't even rea lize that the
airbags have deployed. The airbags a lso inflate
with a great 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 lim it t he occupant's forward move
ment . T ogether they he lp to prevent the driver
and front sea t passenger from h itti ng pa rts of
t h e i nside the veh icle w hile reducing the fo rces
acti ng on the occupant dur ing the cras h. In th is
way they help to reduce the risk of inju ry to the
head and uppe r body i n the crash. Airbags do not
protect the arms or the lower parts of the body.
Both front airbags will not infla te in all frontal
collisions . The trigge ring of the airbag system de
pends on the vehicle deceleration rate caused by
the coll is ion and registered by the electronic con
tro l unit . If this rate is be low the reference value
programmed into the contro l unit, the airbags
will not be triggered, even though the car may be
badly damaged as a resu lt of the co llision. Vehi
cle damage, repa ir costs or even the lack of vehi
cl e damage is not ne cessari ly an indication of
whethe r an a irbag should infla te o r not.
It is not possib le to define a range of vehicle
speeds that w ill cove r every possible k ind and an
gle of impa ct that will always tr igger the airbags ,
s in ce the circumst ances w ill vary cons iderably be
tween one collision and anot her. Important fac
tors include, for examp le, the natu re (hard or
soft) of the object which the car hits, t he angle of
i mpact, vehicle speed, etc . The front airbags will ..,_

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 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
r:::;,page 130.
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 133, 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 .
-

-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

-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.

Federa l Motor Vehicle Safety Standard
(FMVSS) 208, as well as Canada Motor Vehicle
Safety Sta ndard (CMVSS) 208 as app licable at
the time your vehicle was manufactured. The
safety belts for the seats have "pretensioners"
that help to take slack out of the belt system.
The pretensioners are also activated by the elec
tronic control unit for the airbag system.
The front safety be lts also have load limiters to
help reduce the forces applied to the body in a
crash.
The airbag for the driver is in the steering wheel

There is a lot you need to know about the airbags
in your vehicle . We urge you to read the detailed
i nformation about airbags, safety belts and child
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 prote ct ion.
- Even when they deploy, airbags provide only supp lemental protection.
- Airbag work most effectively when used with properly worn safety be lts.
- Therefore, always wear your safety belts and make sure that everybody in your veh icle is
properly restrained .
.&_ WARNING
A person on the front passenger seat, espe
cially infants and small ch ildren, wi ll receive
serious inju ries 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 i f 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 seat ing pos ition.
- For their own safety, all chi ld ren, especially
12 years and younger, should always ride in
the back proper ly restrained for their age
and size .

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
celerat ion 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 cr iteria 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 160, 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

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
