The warn ing light tin the instrument cluster lights up when the igni­

Why safety belts?
Frontal collisions and the law of physics
Frontal crashes create very strong forces for people
riding in vehicles .

Fig . 18 8 T he veh icle
cr ash es into t he wall
Th e physical pr incip les are simple. Bot h the vehicle and the passen­
gers possess energy which varies with vehicle speed and body weight.
Enginee rs call th is energy "kine tic en ergy ."
The higher the speed of the vehicle and the greater the veh icle's
weight, the more 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 SO km/h), the energy increases 4 times!

& WARNING (continued)
• Never let any person ride with their feet on the instrument
panel or sticking out the window or on the seat .
• Never remove a safety belt while the vehicle is moving . Doing
so will increase your risk of being injured or killed .
• Never wear belt s twisted.
• Never wear belts over rig id or breakable objects in or on your
clothing, such as eye glasses, pen s, keys, etc ., a s these may cause
injury.
• Never allow safety belt s to become damaged by being caught
in door or seat hardware .
• Do not wear the shoulder part of the belt under your arm or
otherwise out of position.
• Several layers of h eavy clothing may interfere with correct
positioning of belts and reduce the overall effectiveness of the
sy stem.
• Always keep belt buckles free of anything that may prevent the
bu ckle from latching securely.
• Never u se comfort clips or devices that create slack in the
shoulder belt. However, special clips may be required for the
proper use of some child restraint systems.
• Torn or frayed safety belts can tear , and damaged belt hard­
ware can break in an accident. Inspect belts regularly . If webbing,
bindings, buckles , or retractors are damaged, hav e belts replaced
by an authorized Audi dealer or qualified workshop.
• Safety be lts that have been worn and loaded in an accident
must be repla ced with the correct replacement safety belt by an
authorized Audi dealer. Replacement may be necessary even if
damage cannot be clearly seen. Anchorages that were loaded
must also be inspected.
• Never remove, modify , disas semble, or try to repair the safety
belts yourself .
& WARNING (co ntinued )

A child in a rearward-facing child safety seat installed on the front
passenger seat will be ser iously injured and can be killed if the
front airbag inflates - even with an Advanced Airbag System .
• The inflat ing airbag w ill hit the child safety seat or 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 ser ious personal injury to the child.
& WARNING
If , in exceptional circumstances , you must install a forward-facing
c hild restraint on the front passenger's seat:

lower parts of the body. Front airbags only supplement the three
point s afety be lts i n some fro ntal c ollisions in which t he vehicle de ce l­
eratio n is h igh enough to dep loy the a irbags.
Front airbags will not deploy:
• if the ignition is sw itched off when a cras h occu rs,
• in s ide collisions,
• in rea r-end collisions,
• in rollovers,
• when the cras h deceleration me asured by the ai rbag syste m is less
than t he m in imum threshold needed for airbag dep loyment as regis­
t ere d by the e lectro nic cont rol unit.
The front passenger airbag will also not deploy:
• when the fron t pa sse nger sea t is not o ccupied,
• when the we ight on the front passenge r seat as sense d by the
Advanced Airbag Sys tem in dicates t hat the front airbag on the
passenger side has to be turned off by t he e lectron ic control un it (the
PASSENGER AIR BAG OFF light comes on and st ay s on).
& WARNING
Sitt ing in the wrong posit ion can increa se the risk of serious injury
in crashes .
• To reduce the risk of injury when the airbags inflate , the driver
and passengers must always sit in an upright position , must not
lean against or place any part of their body too close to the ar ea
where the airbags are located.
• Occupants who are unbelted, out of position or too close to the
airbag can be ser iously injured by an airbag as it unfolds with
great force in the blink of an eye=>
page 202.
& WARNING
A child in a rearward-facing ch ild safety seat installed on the front
pa ssenger seat will be seriou sly 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 or 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-f acing child safety seats on the rear seat.
• If you must install a rearward facing child safety seat on the
front p assenger seat because of e xceptional circumstances and
the PASSENGER AIR BAG OFF light does not come on and stay on,
i mmediately install the rear-facing child safety seat in a rear
seating position and have the airbag system inspected by your
authorized Audi dealer.
& WARNING
Objects between you and the airb ag wilt increase the risk of injury
in a crash by interfering with the way the airbag unfolds or by
being pushed into you as the airbag inflates.
• N ever hold things in your hands or on your lap when the vehicle
is in use.
• Never tran sport items on or in the area of the front passenger
seat . Object s could move into the area of the front airbag s during
brak ing or other sudden maneuver and become dangerous projec­
tiles that can cause serious personal injury if the airbags inflate.
• Never place or attach accessories or other objects (such as
cupholders , telephone bra ckets , large, heavy o r bulky objects) on
the doors, over or near the area marked "AIRBAG " on the steering
wheel, instrument panel , seat backrests or between those areas
and yourself . The se obj ect s could cause injury in a crash , especially
when the airbags inflate .
• Never recl ine the front passenger's seat to transport objects.
Items can also move into the area of the side airbag or the front ..,

airbags can b ecome projectiles and cause injury , particularly when
the seat is reclined.
& WARNING
The fine dust created when airbags deploy can c ause breathing
problems
for people with a history of asthma or other breathing
conditions.
• To
reduce the risk of breathing probl ems, those with asthma or
other respiratory conditions should get fresh air right away by
getting out of the vehicle or opening windows or doors.
• If you are in a colli sion in which airbags deploy, wash your
hands and face with
mild soap and water before eating .
• Be careful
not to get the dust into your eyes, or into any cuts or
scratches.
• If the residue should get into your eyes, flush them with
water. •
