- Alw ay s place an d prop erly secure h eavy items in the
luggage com partm en t as fa r fo rwa rd as possi ble.
& WARNING
Improperly stored luggage or other items can fly through the
vehicle causing ser ious personal injury in the event of hard br aking
or an a ccident. To help reduce the risk of serious personal injury :
• Always put objects , for e xample , luggage or other heavy items
in the luggage compartment.
& WARNING
Heavy loads will influence the way your vehicle 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 e venly as possible .
- Place heavy objects as far forward in the luggage compart -
ment as possible .
• Never exceed the Gross Axle Weight Rating or the Gros s
Vehicle Weight Rating specified on the safety compliance sti cker
on the left door jamb. Exceeding permis sible weight standards
c an cau se the veh icle to slide and handle differently .
• Please ob serve information on safe driving:::::,
page 146.
& WARNING
To help prevent poisonous exhaust gas from being dra wn into the
vehicle , always keep the rear l id clo sed while driv ing.
• Ne ver t ransport obje cts larger than those fitting completely
into the luggage area because the rear lid cannot be fully closed.
& W ARNING (continued )
• If you absolutely must drive with the rear lid open, observe the
following notes to reduce the risk of poisoning :
- Close all windows ,
- Close the power top ,
- Open all air outlets in the instrument panel ,
- Switch off the air recirculation ,
- Set the fre sh air fan to the highest speed .
& WARNING
Always make sure that the doors, all windows , the power roof and
the rear lid are securely closed and locked to reduce the ri sk of
injury when the vehicle is not being used.
• After closing the rear lid , always make sure that it i s properly
closed and locked .
• Never leave your vehicle unattended especially with the rear lid
left open. A child could crawl into the vehicle through the luggage
compartment and close the rear lid becoming trapped and unable
to get out . Being trapped in a vehi cle can le ad to serious personal
injury.
• Never let ch ildren play in or around the vehicle.
• Never let pa ssengers ride in the luggage compartment . Vehicle
occupants must always be properly restrained in one of the
vehicle's seating po sition s.
[ i ] Tips
• Air circu lat io n helps to reduce window fogg in g when the power
top is c losed. Stale air escapes to the outside through slots in the
t rim pa nels o n both sides of the luggage co mpartment. Make sure
that these s lots are not b locked. _.

driver has fastened his safety belt, the warning tone will stop and
the warning light will go out .
I f the driver has not buckled -up within about 24 seconds after the
warn ing tone has stopped, the warn ing tone will sound again for
about 6 seconds. The warning tone will sound repeated ly for about
6 seconds at 24 second intervals unti l the driver has buckled-up . The
safety belt warning system is active for about 5 minutes and during
this time the wa rning light in the instrument c luster will stay on.

Why safety belts?
Frontal collisions and the law of physics
Frontal crashes create ve ry strong forces for pe ople ri ding
in vehicles.

c ras he s in to t he wa ll
The physica l principles are simple. Both the vehicle and the passen­
gers possess energy which varies with vehicle speed and body
we ight . Engineers call this energy "kinetic energy ."
The higher the speed of the vehicle and the greater the vehicle's
we ight, the mo re energy that has to be "absorbed" in the crash .
Vehicle speed is the most significant factor. If the speed doub les
from 15 to 30 mph (25 to 50 km/h), the energy increases 4 times!

Safety belts protect
People think it's possible to use the hands to brace the
body in a minor collision . It's simply not true!

Safety belts used properly can make a big difference . Safety belts
help to keep passengers in their seats, gradually reduce energy levels app lied to the body in an accident, and help prevent the
uncontrolled movement that can cause serious injuries . In addition,
safety be lts reduce the danger of being thrown out of the vehic le.
Safety belts attach passengers to the car and give them the benefit
of being s lowed down more gently or "sof tly" through the "give" in
the safety belts, crush zones and other safety features engineered
into today's vehicles. By "absorbing" the kinetic energy
over a
longer period of time, the safety belts make the forces on the body
more "tolerable" and less likely to cause injury.
Although these examples are based on a frontal co llision, safety
belts can a lso substantially reduce the risk of injury in other kinds
of crashes. So, whether you're on a long tr ip or just going to t he
corner store, always buckle up and make sure others do, too. Acci ­
dent statistics show that vehic le occupants properly wearing safety
belts have a lower risk of being injured and a much better chance of
s u rviv ing an acc ident. Proper ly using safety belts also great ly
increases the abi lity of the supplementa l airbags to do their job in a
coll ision. For this reason, wearing a safety be lt is legally required in
most countries including much of the United States and Canada . Although your Audi is equipped with airbags, you sti
ll have to wear
t he safety belts provid ed. Fron t airbags, for example, are activated
only in some frontal collisions. The front airbags are not activated in
a ll frontal co llisions, in side and rear collisions, in ro ll
ove rs or in
cases where there is not enough dece leration through impact to the
front of the vehicle. The same goes for the other ai rbag systems in
your Audi. So, a lways wear your safety belt and make sure
eve ry­
body in your vehic le is properly restrained! •
Important safety Instructions about safety
belts
Safety belts must always be correctly positioned across
the strongest bones of your body.
Always wear safety belts as illustrated and described in
this cha pte r.
Make s ure tha t your sa fe ty belts ar e always ready for us e
and are not damaged .
& WARNING
Not wearing safety belts or wearing them improperl y increases
the risk of serious per sonal injury and death . Safety belt s can w ork
only when used corre ctl y.
• Alway s fa sten yo ur safety belt s correctl y before driving off and
make sure all pa ssenger s are properl y restrained .
• For m aximum protection , safet y belts must alw ays be po si­
tion ed corre ctly on the body .
• Never strap mo re than one person , including sm all children ,
into any single safety belt.
• Never pla ce a s afety belt ove r a child sitting on your lap .
• Alway s ke ep feet in the footwell in front of the seat while the
vehicle is being dr iven .

& WARNING
A person on the front p assenger se at, espe cially infant s and small
c hildren , will re ceive seriou s injuries and can ev en be killed by
being t oo clos e to the airbag when it infl ates.
• Although the Adva nced Airbag System in your ve hicle i s
de signed to turn off the front passenger airb ag i f a n infant or a
s mall child i s on the front pa ssenger seat , nobody can absolutely
gu ara ntee that deployment under these spe cial co nditio ns is
impos sible in all conceivable situations that m ay happen during
the useful life of your vehicle.
• The Adv an ced Airbag Sy stem can deploy in a ccordance with
the "lo w risk" option unde r the U .S. Feder al Stand ard if a child t hat
is heavier than the typi cal on e-year old child i s on th e front
pa sse nger seat an d the other condition s for airb ag dep loym ent

Advanced front airbag system
Your vehicle is equipped with a front Advanced Airbag System in
compliance with United States Federal Motor Vehicle Sa fety Stan ­
dard 208 as applicable 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 frontal crashes. The airbags inflate only
in frontal impacts when the vehic le deceleration 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 overall
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 be lt and wear ing it proper ly . 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 veh ic le 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 with the front airbag 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 192, "Child restraints and Advanced
Airbags".
"S uppression" requi res 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 certified. For
a listing of the child restraints that were used to certify your
vehic le's compliance wi th the US Safety Standard ~

& WARNING
To reduce the risk of injury when an airbag inflates , always wear
safety belts properly.
• If you are unrestrained, leaning forward , sitting sideways or out
of posit ion in any way, your risk of injury is much higher.
• You will also receive serious injuries and could even be killed if
you are up against the airbag or too close to it when it inflates -
even with an Advanced Airbag=> page 168 .
& WARNING
A child in a rearward -facing child safety seat installed on the front
passenger seat will be seriously injured and can be killed if the
front airbag inflates -even with an Advanced Airbag System.
• Although the Advanced Airbag System in your vehicle is
designed to turn off the front airbag when a rearward -facing child
restraint has been installed on the front passenger seat , nobody
can absolutely guarantee that deployment is impossible in all
conceivable situations that may happen during the useful life of
your vehicle.
• The inflating airbag will hit the child safety seat or infant
carrier with great force and will smash the child safety seat and
child against the backrest , center arm rest , door, or roof .
• Alway s install rearward -facing child restraints in the back seat . •

__________________________________________________ A_ i_ r _b _a...; g::- s_ y=--- s_t _e _m ___ lffllll
& WARNING (continued )
• Always make sure that the side airbag can inflate without inter­
ference :
- 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 inflate.
- 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.
• The airbag system can be activated only once. After an airbag
has inflated, it must be replaced by an authorized Audi dealer or
qualified technician who has the technical information , training
and special equipment nece ssary.
• The airbag system can be deployed only once . After an airbag
has been deployed , it must be replaced with new replacement
part s designed and approved especially for your Audi model
version. Replacement of complete a irbag systems or airbag
components must be performed by qualified workshops only .
Make sure that any airbag service action is entered in your Audi
Warranty
& Maintenance booklet under AIRBAG REPLACEMENT
RECORD .
• In accidents when an airbag is deployed , the vehicle battery
s eparates the alternator and the starter from the vehicle electrical
system for safety reasons with a pyrotechnic circuit interrupter.
-Work on the pyrotechnic circuit interrupter must only be
performed by a qualified dealer -risk of an accident !
- If the vehi cle or the circuit interrupter is scrapped , all appli ­
cable safety precautions must be followed . •

child is available. In these exceptional situations, the use of a lap
belt is better than permitting the chi ld to remain totally unre ­
strained . But remember: a lap belt cannot provide the same level of
protec tion as a proper child restraint or a t hree -point lap and
shoulder belt if the child is big enough . Also, using a lap belt for
younger child ren, who should be using a chi ld restraint, may violate
l aws in your state or Prov ince .
Never use a lap belt alone to restrain a chi ld that weighs less than
about 80 lbs (36 kg) and who is less than 4'9" ta ll. A lways remember
that chi ldren do not have the pronounced pelvic structure required
for the proper function of lap belts. If a lap belt is only restraint
system available, then the child's safety absolutely requires that the
l ap be lt be fastened snug ly and as low as possible around the pelv is
let a lap belt pass over the chi ld's stomach or abdomen .
& WARNING
Using wrong child restraints or improperly in stalled child
restraint s can cau se serious personal inju ry or death in a cr ash.

Safe ty belts for the rear seats and the fr ont passenger can
be locked with the c onvertible locking retractor to prop­
erly secure child safety seats.
The safety belts emergency locking retractors fo r the rear seats
safety be lts and for the front passenger's seat safety belt have a
conve rtible locking ret ractor for child restraints . The safety belt
must be locked so that belt webbing cannot unreel. The retractor
can be activated to lock the safety be lt and prevent the safety belt
webbing from loosening up during normal dr iving. A child safety
seat can only be properly instal led when the safety belt is locked so
that t he child and child safety seat w ill s tay i n place .
Always remember: Even though your vehicle is equipped with an
Advanced Airbag system, al l children, especially those 12 years and
younger, should always ride in the back seat p roperly restra ined for
