Safety belts
General notes
Always wear safety belts!
Wearing safety belts correctly saves lives!
This chapter explains why safety belts are necessary, how
they work and how to adjust and wear them correctly.
- Read all the information that follows and heed all of the
instruct ions and WARNINGS.
& WARNING
Not wearing safety belts or wearing them improperly increases
the risk of serious personal injury and death.
• Safety belts are the single most effective means available to
reduce the risk of serious injury and death in automobile acci­
dents . For your protection and that of your passengers , always
correctly wear safety belts when the vehicle is moving.
• Pregnant women, injured, or physically impaired persons must
also use safety belts . Like all vehicle occupants, they are more
likely to be seriously injured if they do not wear safety belts . The
best way to protect a fetus is to protect the mother -throughout
the entire pregnancy. •
Number of seats
Your Audi has a total of four seating positions: two in the front and
two in the rear. Each seating position has a safety belt .
Controls and equip­ ment Safety first
Vehicle operation
& WARNING
Not wearing safety belts or wearing them improperly increases
the risk of serious personal injury and death .
• Never strap more than one person, including small children,
into any belt. It is especially dangerous to place a safety belt over
a child sitting on your lap.
• Never let more people ride in the vehicle than there are safety
belts available.
• Be sure everyone riding in the vehicle is properly restrained
with a separate safety belt or child restraint. •
Safety belt warning light ~
Your vehicle has a warning system for the driver and (on
USA models only) front seat passenger to remind you
about the importance of buckling-up.
Before driving off, always:

Because the passengers of this vehicle are not using safety belts
=:> page 180, fig. 185, they will keep moving at the same speed the
vehicle was moving just before the crash, until something stops
them -here, the wall
=:> page 180, fig. 186.
The same principles apply to people sitting in a vehicle that is involved in a frontal collision. Even at city speeds of 20 to 30 mph
(30 to 50 km/h), the forces acting on the body can reach one ton
(2,000 lbs. or 1,000 kg) or more . At greater speeds, these forces are
even higher.
People who do not use safety belts are also not attached to their
vehicle. In a frontal collision they will also keep moving forward at
the speed their vehicle was travelling just before the crash. Of course, the laws of physics don't just apply to frontal collisions, they
determine what happens in all kinds of accidents and collisions. •
What happens to occupants not wearing
safety belts?
In crashes unbelted occupants cannot stop themselves
from flying forward and being injured or killed. Always
wear your safety belts!
Safety first

Safety belts

a safety belt will fly
forward and strike the
driver
Unbelted occupants are not able to resist the tremendous forces of
impact by holding tight or bracing themselves. Without the benefit
of safety restraint systems, the unrestrained occupant will slam
violently into the steering wheel, instrument panel, windshield, or
whatever else is in the way=:> fig. 187. This impact with the vehicle
interior has all the energy they had just before the crash.
Never rely on airbags alone for protection. Even when they deploy,
airbags provide only additional protection. Airbags are not
supposed to deploy in all kinds of accidents. Although your Audi is
equipped with airbags, all vehicle occupants, including the driver,
must wear safety belts correctly in order to minimize the risk of
severe injury or death in a crash.
Remember too, that airbags will deploy only once and that your
safety belts are always there to offer protection in those accidents
in which airbags are not supposed to deploy or when they have
already deployed. Unbelted occupants can also be thrown out of the
vehicle where even more severe or fatal injuries can occur.
It is also important for the rear passengers to wear safety belts
correctly . Unbelted passengers in the rear seats endanger not only
themselves but also the driver and other passengers=:> fig. 188. In a
frontal collision they will be thrown forward violently, where they can hit and injure the driver and/or front seat passenger. •

[ i ] Tip s
The sa fety belt pr etensioner can on ly be activated once .
• I n minor frontal and side collis ions , in rear-end collisions, in a
rollover and in accidents involving very litt le impact force, the safety
belt pretension er are not activa ted.
• I n the case of a side crash, the safety belt p retensioners will acti ­
vate on the driver 's or front passenger 's sides only , depending on
which s ide of the vehic le the crash occu rs.
• When the safety be lt pretensioners are activated , a fine dust is
released . This is normal and is not caused by a fire in the vehicle.
• T he relevant safety requirements must be observed when the
vehic le o r componen ts of the sys tem are scrapped . An au thor ized
Audi dealer or qua lified workshop is familiar with these regula tions
and wil l be p leased to pass on the information to you .
• Be sure to observe all safety, environmenta l and other regula ­
tions if the vehic le or individual parts of the system, particu larly the
safety belt or airbag , are to be disposed . We recommend you have
your au thorized Audi dea ler perform this service for you .•
Service and disposal of safety belt
pretensioner
The safety bel t pretensio ners are parts of the sa fety be lts on your
Audi . Installing , removing, servicing or repairing of bel t preten ­
sioners can damage the safety be lt system and prevent it from
working correctly in a collision .

& WARNING
Improper care, servicin g and repair procedure s can increase the
ri sk of personal injury and death by preventing a safety belt
preten sioner from a ctivating when needed or activating it unex­
pe ctedly :
• The belt preten sioner system can be a ctivated only once. If belt
pretens ioners have been a ctivated , the syste m must be repla ced .
• Never repair , adjust , or change any parts of the safet y belt
system .
• Safety belt system s incl uding safety belt pretensioner s cannot
be repaired . Speci al procedures are required for removal , installa ­
tion and di spo sal of this sy stem .
• For any work on the safety belt system , we strongly re com ­
mend that you see your authorized Audi dealer or qualified techni ­
cian who has an Audi approved repair m anual , train ing and spe cial

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 179 .
& 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 help 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 -
ev en with an Advanced Airbag .

& 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.
• The inflating airbag will hit the child safety seat o r infant
carrier with great force and will smash the child safety seat and
child against the backrest , center armrest , door or roof.
• Always install rear-facing child safety seats on the rear seat.
• If you must install a rearward facing child safety seat on the
front passenger seat because of exceptional circumstances and
the PASSENGER AIR BAG OFF light does not come on and stay on,
immediately install the rear-facing child safety seat in a rear
seating position and have the airbag system inspected by your
authorized Audi dealer.
• Forward-facing child safety seats installed on the front
pa ssenger's seat may interfere with the deployment of the airbag
and cause serious personal injury to the child .
& WARNING
If, in exceptional circumstances , you must install a forward-facing
child restraint on the front passenger's seat:
Controls and equip­ ment Safety first
Vehicle operation
& WARNING (continued)
• Always make sure the forward-facing seat has been designed
and certified by its manufacturer for use on a front seat with a
passenger front and side airbag .
• Never put the forward-facing child restraint up against or very
near the instrument panel .
• Always move the passenger seat into its rearmost position in
the seat's fore and aft adjustment range, as far away from the
airbag as possible before installing the forward-facing child
restraint. The backrest must be adjusted to an upright position .
• Make sure that the PASSENGER AIR BAG OFF light comes on
and stays on all the time whenever the ignition is switched on.
& WARNING
To reduce the risk of serious injury, make sure that the PASSENGER
AIR BAG OFF light will be displayed whenever a child restraint is
installed on the front passenger seat and the ignition is switched
on.
• If the PASSENGER AIR BAG OFF light does not stay on , perform
the checks described
~ page 199 , "Monitoring the Advanced
Airbag System" .
• Take the child restraint off the front passenger seat and install
it properly at one of the rear seat positions if the PASSENGER AIR
BAG OFF light does not stay on .
• Have the airbag system inspected by your authorized Audi
dealer immediately .
• Always carefully follow instructions from child restraint manu ­
facturers when installing child restraints .

• Even when they deploy, airbags provide only supplemental
p rotect ion .
• Airbag work most effectively when used with properly worn
safety belts .
• Therefore , always wear your safety belts and make sure that
everybody in your vehi cle is properly restrained .
& WARNING
A person on the front passenger seat , especially infants and small
children, will receive serious injuries and can even be killed by
being too close to the a irbag when it inflates .
• Although the Advanced Airbag System in your vehicle is
designed to tu rn off the front passenger airbag if an infant or a
small child is on the front pa ssenger seat, nobody can absolutely
guarantee that deployment under these special cond itions is
impossible in all conceivable situations that may happen during
the useful life of your vehi cle .
• The Advanced Airbag System can deploy in accordance with
the "low risk" option under the U .S . Federal Standard if a child that
is heavier than the typical one -year old child 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 position .
• For their own safety , all children , espec ially 12 years and
younger, should always ride in the back properly restrained for
their age and size . •

Advanced Airbag System components
The front passenger seat in your vehicle has a lot of very important
parts of the Advanced A irbag System in it. These parts inc lude the
weight -sensing mat, sensors, wiring, brackets, and more. The func -
Controls and equip­ ment Safety first Vehicle operation tion of the system in the front passenger seat is checked by
the elec­
tronic contro l unit when the ignition is on . The control unit monitors
the Advanced Airbag System and turns the a irbag indicator light on
when a malfunction in the system components is detected . The
function of the airbag indicator light is described in greater detail below. Because the front passenger seat conta ins important parts
of the Advanced Airbag System, you must take care to prevent 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.
T he front Ad van ced Airbag System consi sts of th e
following:
• Crash sensors in the front of the vehicle that measure vehicle
acce leration/deceleration to provide information to the Advanced
A irbag System about the sever ity of the crash .
• An electronic control unit, with integrated crash sensors for front
and side impac ts. The control unit "decides" whether to fire the
front airbags based on the information received from the crash sensors . The control unit also "decides" whether the safety belt
pretensioners should be activated.
• An Advanced Airbag w ith gas generator and contro l valve for the
driver inside the steering wheel hub.
• An Advanced Airbag with gas generator and contro l valve inside
the instrument panel for the front passenger .
• A weight -sensing mat under the upholstery padding of the front
passenger seat cushion that measures the total weight on the seat .
The information registered is sent continuously to the e lectronic
control unit to regu late dep loyment of the front Advanced Airbag on
the passenger s ide.
• An airbag monito ring system and indicator light in the instru ­
ment cluster=> page

& WARNING
The fine dust created when airbags deploy can cause breathing
p roblems for people with a history of asthma or other breathing
c onditions .
• To reduce the risk of breathing problems , those with asthma or
other respir atory cond itions should get fresh air right away by
getting out of the vehicle or opening windows or doors.
• If you are in a collision in which airbags deploy, wash your
