-Make sure that your passengers also buck le up and prop ­
erly wear the ir safety belts .
- Protect your children with a child restraint system appro-
priat e for the si ze and age of the child ren.
The warn ing light tin the instrument cluster lights up when the igni­
tion is switched on as a reminder to fasten the safety belts. In addi­
tion, you wi ll hear a war ning sound.
After the ignition is switched on, the warning tone will come on for abou t 6 seconds along with a t warn ing light in the inst rument
cluster if e ither the driver or (on USA models o nly) front seat
passenge r has not fastened their safety bel t. As soon as the driver
and front seat passenger have fastened the safety belt, the warning
tone will stop and the warning light will go out.
If both the driver and front seat passenger have not buckled- up
within about 24 seconds after the warning tone has stopped, the
wa rning tone w ill sound aga in for about 6 seconds. The warn ing tone
w ill sound repeatedly for about 6 seconds at 24 second interva ls unt il
bo th the driver and fron t passenger have bu ckled -up. The safety belt
warning system is active for about 5 minutes and during this time the
warning light in the instrument cluster wi ll stay on.
Fasten your safety b elt now and make sure that your pa ssengers
also properly put on their safety belt s. •

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

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!

Because the passengers of this vehicle are not using safety belts
=>
page 191, fig. 187, they will keep moving at the same speed the
vehicle was moving just before the crash, until something stops them
- here, the wall =>
page 191, fig. 188.
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 deter­
mine 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!

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. 189. 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. 190. In a
frontal collision they will be thrown forward violently, where they can
hit and injure the driver and/or front seat passenger. •

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 diffe rence. Safety belts
help to keep p assengers in the ir seats, gradually reduce energy leve ls
applied to the body in an accident, and help prevent the uncontrolled
movemen t that can cause serious injuries . In add ition, safety belts
reduce the danger of being thrown out of the vehicle.
Safety be lts attach passengers to the car and give them the benefit of
being slowed down mo re gent ly or "softly" through the "give" in the
safety belts, crush zones and other safety features engineered into
today 's vehicles. By "absorbing" the k ineti c ene rgy over a longe r
period of time, the safety belts make the forces on the body more
"tolerable" and less likely to cause injury.
Al though these exam ples are based on a frontal co llision, safety belts
can also substantia lly reduce the risk of injury in other kinds of
crashes. So, whethe r you're on a long tr ip or just go ing to the corner
store, always bu ckle up and make sure others do, too. Accident statis­
ti cs show t hat vehicle occupants properly weari ng s afety belts have a
lower risk of being injured and a much better chance of surviving an
acc iden t. Prope rly usi ng sa fe ty belts a lso great ly increases the ab ility
of the supplemental a irbags to do their job in a collision. For this
reaso n, wearing a safety belt is lega lly requ ired in most countr ies
including much of the United States and Canada.
Safety first Vehicle OP-eration
Safety belts
Although your Audi is equipped with a irbags, you still have to wear
the safe ty belts provi ded. Fron t airbags, for ex ample, are activa ted
only in some frontal collisions. The front a irbags are not act ivated in
all fronta l co llisions, in side and rear co llisions, in roll overs or i n cases
whe re there is not enough decelerat ion through impact to the front
of the vehicle . The same goes for the ot her airbag systems in your
Audi. So, always wear your safety bel t and make sure eve rybody in
your vehicle is properly restrained! •

Safety belt pretensioners
How safety belt pretensioners work
In front, side and rear -end collisions above a particular
s everity, safety belts are tensioned automatically.
Th e safety bel ts are eq uipped w ith safety bel t pre tensioners. The
system is activated by sensors in front, s ide and rear-end co llisions of
great severity . This tig htens the belt and takes up bel t slack ~
& in
"Service and disposal of safety be lt pretensioner" . Taking up the slack
helps to red uce forward occupant movement d uring a collision .
0 Note
Never let the be lt remain over a rear seat back that has been folded
forward .
W Tips
The safety belt p retensioner can only be ac tivated o nce.
• In minor fronta l and side co llisions, in rear -end collisions, in a roll­
over and in acc idents involving very litt le impact force, the safety belt
pretensioner are not activated.
• When the safety belt pretensioners are activated, a fine dust is
re lease d. This is normal an d is not caused by a fire in the ve hicle.
• The relevant safety requirements must be observed when the
veh icle o r com ponen ts of the system a re s crapped. An au thor ized
Audi dealer or qualif ied workshop is familiar w it h these reg ulations
and wi ll be pleased to pass on the informatio n to yo u.
• Be sure to observe all safety, enviro nmental and other reg ulat ions
if the vehi cle o r ind iv id ual parts o f the system, p art icularly the s afe ty
be lt or a irbag, are to be d isposed . We recommend you have your
author ized A udi dealer perform this service for yo u.•
Service and disposal of safety belt
