Tie-downs
The luggage compartment is equipped with four tie­
downs to secure luggage and other items.
Use the tie -downs to secure your cargo properly~ page 199,
"Loading the luggage compartment".
In a collision, the laws of physics mean that even smaller items that
are loose in the vehicle will become heavy missiles that can cause
serious injury. Items in the vehicle possess energy which vary with
vehicle speed and the weight of the item. Vehicle speed is the most
significant factor.
For example, in a frontal collision at a speed of 30 mph (48 km/h),
the forces acting on a 10-lb (4.5 kg) object are about 20 times the
normal weight of the item. This means that the weight of the item
would suddenly be about 200 lbs. (90 kg). You can imagine the inju­
ries that a 200 lbs. (90 kg) item flying freely through the passenger
compartment could cause in a collision like this.
& WARNING
Weak, damaged or improper straps used to secure items to tie ­
downs can fail during hard braking or in a collision and cause
serious personal injury.
• Always use suitable mounting straps and properly secure
items to the tie-downs in the luggage compartment to help
prevent items from shifting or flying forward as dangerous
missiles.
• When the rear seat backrest is folded down, always use suit­
able mounting straps and properly secure items to the tie-downs
in the luggage compartment to help prevent items from flying
forward as dangerous missiles into the passenger compartment.
• Never attach a child safety seat tether strap to a tie-down. •

Reporting safety defects
If you believe that your vehicle has a defect
which could cause a crash or could cause
injury or death, you should immediately inform
the National Highway Traffic Safety Adminis­
tration (NHTSA) in addition to notifying Audi of
America, Inc. If NHTSA receives similar complaints, it may open an investigation, and
if it finds that a safety defect exists in a group
of vehicles, it may order a recall and remedy
campaign. However, NHTSA cannot become involved in individual problems between you,
your dealer, or Audi of America, Inc.
To contact NHTSA, you may call the Vehicle
Safety Hotline toll-free at 1-888-327-4236 (TTY: 1-800-424-9153);

Improperly worn safety belts
Incorrectly positioned safety belts can cause severe inju­
nes.
Wearing safety belts improperly can cause serious injury or
death. Safety belts can only work when they are correctly positioned on the body. Improper seating positions reduce
the effectiveness of safety belts and w ill even increase the
risk of injury and death by moving the safety belt to critical
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
position. A driver is responsible for the safety of all vehicle
occupants and especially for children. Therefore:
-Never permit anyone to assume an incorrect sitting pos i­
tion in the vehicle while traveling ~& .
& 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 being used.
• Always read and heed all WARNINGS and other important infor­
mation
~ page 205. •
Safety belt tensioners
How safety belt pretensioners work
In front, side and rear collisions above a particular
severity, safety belts are tensioned automatically.
The safety belts are equipped with safety belt pretensioners . The
system is activated by sensors in front, side and rear collisions of
great severity . This tightens the belt and takes up belt slack~
& in
"Service and disposal of safety belt pretensioner" on
page 211.
Taking up the slack helps to reduce forward occupant movemen t
during a collision.
0 Note
Never let the belt remain over a rear seat back that has been folded
forward .
[ i] Tips
The safety belt pretensioner can only be activated once.
• In minor frontal, side and rear -end collisions, in a rollover and in
accidents involving very little impact force, the safety belt preten­
sioner are not activated .
• When the safety belt pretensioners are activated, 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. A qualified deal ­
ership is familiar with these regulations and will be pleased to pass
on the information to you.
• Be sure to observe all safety, environmental and other regula­
tions if the vehicle or individual parts of the system, particularly the
safety belt or airbag , are to be disposed . We recommend you have
your authorized Audi dealer perform this service for you. •

Safety b elts -----------------=------
Service and disposal of safety belt
pretension er
The safety belt pretensioners are parts of the safety belts on your
Audi. Installing, remov ing, servic ing or repair ing of belt preten ­
sioners can damage the safety be lt system and prevent it from
working correctly in a coll ision.
T here are some important things you have to know to make sure
that the effectiveness of the system will not be impaired and that
discarded components do not cause injury or po llute the environ­
ment .
& WARNING
Improper car e, servicing and repair proc edure s can incr ease the
ri sk of p ers onal injury and d eat h by pre venting a safety b elt

Airbag syst em -----------------=~-
repair costs or even the lack of vehicle damage is not necessari ly an
indication of whether an airbag should inflate or not.
It is not possible to define a range of vehicle speeds that will cover
every possible kind and ang le of impact that wil l always trigger the
airbags, since the circumstances wil l vary considerab ly between
one collision and another. Important factors include, for example,
the nature (hard or so ft) of the object which the car hits, the angle
of impact, vehicle speed, etc. The front airbags wi ll also not inflate
in side or rear co llisions, or in roll -overs .
Al way s rem ember : Airbags wi ll deploy only once, and on ly in certain
kinds of coll isions . Your safety belts are always there to offer protec­
tion in those situat ions in wh ich airbags are not supposed to deploy,
or when they have already deployed; for example, when your vehic le
strikes or is struck by another a fter the first coll ision.
T his is just one of the reasons why an airbag is a supplementary
restraint and is not a substitute for a sa fety be lt. The airbag system
works most effectively when used with the safety be lts. Therefore ,
a lways prope rly wea r your safety belt s =>
page 202 .
& WARNING
Sitting too clo se to the steering wheel or in strument panel will
de crease the effect ivene ss of the airbags and will incr ease the risk
of personal injury in a collision.
• Never sit closer than 10 in ches (25 cm) to the steering wheel or
in strument panel.
• If you c annot sit more than 10 in ches (25 cm ) from the steering
wheel , inve stiga te whether adaptive equipment may be available
to held you reach the pedal s and in crease your se ating dist ance
from the steering wheel.
• If you are unrestra ined , leaning forward , sittin g side ways or out
of position in any way , your risk of injury i s much higher .
• You will also receive serious injur ies and could even be killed if
you are up again st the airba g or too clo se to it when it infl ates -

Advanced front airbag system
Your vehicle is equipped with a front Advanced Airbag System in
compliance with United States Federal Motor Veh icle Sa fety Stan ­
dard 208 as applicab le at the time your vehicle was manufactured.
Controls and equip­ ment Safety first Vehicle operation The front Advanced Airbag System supplements the safety belts to
provide additional protection for the driver's and front passenger's
heads and upper bodies in fronta l crashes. The airbags inflate only
in frontal impacts when the vehic le dece leration is high enough.
The front Advanced Airbag System for the front seat occupants is not a substitute for your safety belts. Rather, it is part of the overa ll
occupant restraint system in your vehicle. A lways remember that
the airbag system can only help to protect you, if you are sitting
upright, wear ing your safety belt and wearing it properly . This is why
you and your passengers must a lways be properly restrained, not
just because the law requires you to be .
The Advanced A irbag System in your vehicle has been certified to
meet the " low risk" requirements for 3 and 6 year-o ld children on the
passenger side and very small adults on the driver side. The low risk
deployment criteria are intended to he lp reduce the risk of injury
through interact ion wi th the front a irbag that can occur, for
examp le, by being too close to the steering whee l and instrument
panel when the airbag inflates.
In addition, the system has been certified to comply with the
"suppression" requirements of the Safety Standard, to turn off the
front airbag for infants 12 months old and younger who are restrained on the front passenger seat in child restraints that are
listed in the Standard:::::,
page 236, "Child restraints and Advanced
Airbags".
"Suppression" requires the front ai rbag on the passenger side to be
turned off if:
• a child up to about one year of age is restrained on the front
passenger seat in one of the rear-facing or forward -facing infant
restraints listed in Federal Motor Vehicle Safety Standard 208 with
wh ich the Advanced Airbag System in your vehicle was certif ied. For
