0 ::..:: co ..... ..... A WARNING
Improperly stored luggage or other items can
fly through the vehicle causing serious per­
sonal injury in the event of hard braking or an
accident . To help reduce the risk of serious
personal injury:
- Always put objects, for example, luggage or
other heavy items in the luggage compart­
ment.
- Always secure objects in the luggage com­
partment using the tie-down eyelets and
suitable straps.
A WARNING
Heavy loads will influence the way your vehi­
cle handles. To help reduce the risk of a loss
of control leading to serious personal injury:
- Always keep in mind when transporting
heavy objects, that a change in the center of
gravity can also cause changes in vehicle
handling:
-Always distribute the load as evenly as
possible .
- Place heavy objects as far forward in the
luggage compartment as possible.
- Never exceed the Gross Axle Weight Rating
or the Gross Vehicle Weight Rating specified
on the safety compliance sticker on the left
door jamb. Exceed ing permissible weight
standards can cause the veh icle to slide and
hand le differently.
- Please observe information on safe driving
qpage 121.
A WARNING
To help prevent poisonous exhaust gas from
being drawn into the vehicle, always keep the
rear lid closed while driving.
- Never transport objects larger than those
fitting completely into the luggage area be­
cause the rear lid cannot be fully closed.
- If you absolutely must drive with the rear lid
open, observe the fo llowing notes to reduce
the risk of poisoning:
- Close all windows,
- Close the sunroof,
Driving safety
-Open all air outlets in the instrument pan­
el,
- Switch off the air recirculation
,
- Set the fresh air fan to the highest speed .
A WARNING
=
Always make sure that the doors, a ll win-
dows, the sunroof and the rear lid are secure­
ly closed and locked to reduce the risk of in­
jury when the vehicle is not being used.
- After closing the rear lid, always make sure
that it is properly closed and locked .
- Never leave your vehicle unattended espe­
cially with the rear lid left open . A child
could crawl into the vehicle through the lug­
gage compartment and close the rear lid be­
coming trapped and unable to get out . Be­
ing trapped in a vehicle can lead to ser ious
personal injury.
- Never let children play in or around the vehi­ cle .
- Never let passengers ride in the luggage
compartment . Vehicle occupants must al­
ways be properly restrained in one of the ve­
h icle 's seat ing positions.
(D Tips
-Air circulation helps to reduce window fog­
ging . Stale air escapes to the outs ide
through vents in the tr im panel. Be sure to
keep these slots free and open.
- The tire pressure must correspond to the
load. The t ire pressure is shown on the tire
pressure label. The tir e pressure label is lo­
cated on the driver's side B-pillar . The tire
pressure label lists the recommended cold
tire inflation pressures for the vehicle at its
maximum capacity weight and the tires that
were on your vehicle at the time it was man­
ufactured. For recommended tire pressures

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
c:;, page 167.
.&_ WARNING
Imprope rly pos itioned safety be lts can cause
ser ious injury in an accident
c:;, page 134,
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
the vehicle

(D Tips
With the front seats, the height adjustment of the seat can also be used to adjust the po­
sition of the safety belts.
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
c>_& .
A WARNING
Improperly worn safety belts increase the risk
of serious personal injury and death whenever
a vehicle is being used.

- Always make sure that all vehicle occupants
are correctly restrained and stay in a correct
seating position whenever the vehicle is be­
ing 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. .,_

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 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 ..,_

..... N
0 ::..:: co ..... ..... 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 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 .
-
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
r:::;,page 122.
-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
r e p laced.
- Use o nly orig inal equipment airbags ap ­
p roved by A udi a nd insta lled by a trained
technici an who has the necessary tools and
diagnostic equipment to properly replace
any airbag in yo ur vehicle and assu re system
effect iveness in a crash.
- Never permit salvaged or recycled airbags to

Airbag syste m
Front airbags
Description of front airbags
The airbag system can provide supplemental
protection to properly restrained front seat occu­
pants.
Fig. 152 Location of driver airbag: in steering whee l
Fig. 153 Location of front passenger's airbag: in the in­
strument panel
Your veh icle is equipped with an "Advanced Air­
bag System" in compliance with Un ited States
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
hub
<=>fig . 152 and the airbag for the front pas­
senger is in the instrument panel
<=>fig. 153. The
general location of the airbags is marked "AIR­
BAG".

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 .

..... N
0 ::..:: co ..... ..... greater detail below. Because the front passen­
ger seat contains important parts of the Ad­
vanced A irbag System, you must take care to pre ­
vent it from being damaged. Damage to the seat may prevent the Advanced Airbag for the front
passenger seat from doing its job in a crash .
The front Adv anced Airb ag Sy stem con sist s
of the following :
-Crash sensors in the front of the vehicle that
measure vehicle accelerat ion/decelerat io n to
provide information to the Advanced Airbag
System about the severity of the crash .
- An electronic control un it, with integrated
crash sensors fo r front and side impacts . The
contro l unit "decides" whether to fire the front
airbags based on the information received from
the crash sensors. The control unit also "de ­
cides" whether the safe ty be lt pretens ioners
sho uld be activated.
- An Advanced Airbag wi th gas generato r and
contro l valve for the driver ins ide the steer ing
whee l hub .
- An Advanced Airbag with gas generator and
contro l valve inside the instrument pane l for
the front passenger.
- A weight -sensing mat under t he upho lstery
padding of the front passenger seat cushion
that meas ures the total weight on the seat . The
information registered is sent continuously to
the electron ic control unit to regulate dep loy­
ment of the front Adva need A irbag on the pas­
senger side.
- An airbag monitoring system and indicator
light i n the instrument cluster
¢ page 148.
-A sensor in each front seat registers the dis­
tance between the respective seat and the
steering wheel or instrument panel. The infor­
mation reg istered is sent cont inuous ly to the
electroni c control unit to regulate deployment
of the fro nt Adv a need A irbags.
- T he

side has been turned off.
- A se nsor below the safe ty bel t lat ch fo r th e
front seat passenger to meas ure the tens ion on
Airb ag sys tem
the sa fe ty belt. The tension on the safety belt
and the weight registered by the weight-sens­
ing mat help the contro l unit "decide" whether
the front airbag for the front passenger seat
should be turned off or not¢
page 139, Child
restraints on the front seat -some important
things to know.
- A sensor in the safety belt latch for the driver
and for the front seat passenger that senses
whether that safety belt is latched o r not and
t ransmits this information to t he electronic
cont rol un it.
_& WARNING
Da mage to the front passenge r seat can pre­
vent the front airbag from working properly.
- Imp roper repair or disassembly of the fro nt
passenger and driver seat will p revent the
Advanced Airbag System from f unct ioning
p roperly.
- Repairs to the front passenger seat must be
performed by qualified an d properly trained
wo rkshop personne l.
- Never remove the front passenge r or driver
seat from the vehicle.
- Never remove the upholstery from the front
passenger seat.
- Never disassemble o r remove par ts from the
seat o r disconnect w ires from it.
- Never ca rry sharp objects in your pocke ts or
p la ce them on the seat. If the weight-sens­
ing mat in the passenger seat is punctu red
it cannot work proper ly.
- Never carry things on your lap or carry ob­
jects on the passenge r seat. S uch items can
increase the weight reg istered by the
weight-sensing mat and send the wrong in­
formation to the a irbag control unit.
- Never store items unde r the front passenger
seat. Parts of the Advanced Airbag System
under the passenger seat could be dam­
aged, p reventing them and the airbag sys­
tem from worki ng p roper ly.
- Never p lace seat covers or replacement up­
holstery tha t have not been specifically ap­
p roved by A udi on the front seats.
- Seat covers can prevent the Advanced A ir­
bag Sys tem from recognizing chi ld

Airbag syste m
-Never place or attach accessories or other
objects (such as cupholders, telephone
brackets, large, heavy or bulky objects) on
the doors, over or near the area marked "AIRBAG" on the steering wheel, instru­
ment panel, seat backrests or between
those areas and yourself. These objects
could cause injury in a crash, especially
when the airbags inflate.
- Never recline the front passenger's seat to
transport objects. Items can also move into
the area of the side airbag or the front a ir­
bag during braking or in a sudden maneu­
ver. Objects near the airbags can become projectiles and cause injury, particularly
when the seat is reclined.
A WARNING
The fine dust created when airbags deploy can
cause breath ing problems for people w ith a
history of asthma or other breathing condi­
t ions.
- To reduce the risk of breathing problems,
those w ith asthma or other respiratory con­
ditions should get fresh air right away by
gett ing out of the vehicle o r opening w in­
dows or doors.
- If you are in a collision in which airbags de­
ploy, wash your hands and fa ce with mild
soap and water before eat ing.
- Be careful not to get the dust into your eyes,
o r into any cuts or sc ratches.
- If the resid ue should get into yo ur eyes,
flush them with water.

r=>page 19
comes when the vehicle is be ing used, h ave
the system inspected immediate ly by yo ur
authorized Aud i dealer. It is possible that
the airbag will inflate when it is not s up­
posed to, or will not inflate when it should.

-Even though your vehicle is equipped with
an Advanced A irbag System, make certain
that all children, espec ia lly 12 years and
younger, always ride on the back seat prop­
erly restrained for their age and s ize.
- Always install forward or rear-facing child
safety seats on the rear seat -even with an
Advanced A irbag System.
- If you must install a rearward-facing child
safety seat on the front passenger seat be­
cause of exceptional circumstances and the
PASSENGER AIR BAG OFF l ight does not
appear and s tay on, immedi ately ins tall the
rear-facing child safety seat in a re ar seat ing
position and have the a irbag system in ­
spected by your a uthorized Audi dea ler.
- A t ight tether or other s trap on a rearward­
facing chi ld restraint attached to the front
passenger seat can put too much pressure
on the weight-sensing mat in the seat and
register more weight than is actually on the
seat. The heavier weight registered can
make the system work as thoug h an adu lt
were on the seat and deploy the Advanced
Airbag when it must be suppressed causing
serious or even f atal injury to the child.
- If, in exceptional circumstances, you must
install a forward-fa cing child res traint on
the front p assenge r seat, always move the
seat into i ts rearmost posi tion in the sea t's
fore and aft ad justment range, as far away
from the ai rbag as possible . The back rest
must be adjusted to an upr ight position.
Make sure that the
