Improperly worn safety belts
Incorrectly positioned safety belts can cause severe inju­
ries.
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 will 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 posi­
tion. A driver is responsible for the safety of all vehicle occu­ pants and especially for children . Therefore:
- Never permit anyone to assume an incorrect sitting posi­
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
information =>

Safety belt pretensioners
How safety belt pretensioners work
In front, side and rear-end 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-end collisions of
great severity. This tightens the belt and takes up belt slack~
& in
" Service and disposal of safety belt pretensioner" on
page 205 .
Taking up the slack helps to reduce forward occupant movement
during a collision. ..

_______________________________________________ S_ a_ f_ e_ t_ y_ b_ e_ lt_s __ _
[I) Tips
The safety belt pretensioner can only be activated once.
• In minor frontal and side collisions, in rear-end collisions, in a ro ll­
over and in acc idents involving very little impact force, the safety belt
pretensioner are not activated.
• When the safety belt pretensioner is activated, a fine dust is
re leased . This is norma l 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
ersh ip is familiar with these regulat ions and will be pleased to pass on
the information to you.
• Be sure to observe all safety, environmental and other regulations
if the vehicl e or individual parts of the system, particularly the safety
belt or a irbag, are to be disposed. We recommend you have your
authorized Audi dea ler perform this service for you .•
Service and disposal of safety belt
pretensioner
Th e safety belt pretensioners are parts of the safety belts on your
Audi. Installing, removing, servicing or repairing of belt preten­
sioners can damage the safety belt system and prevent it from
work ing correctly in a collision.
Th ere are some important things you have to know to make s ure that
the effectiveness of the system w ill not be impaired and that
discarded components do not cause injury or pollute the environ­
ment.
& WARNING
Improper care, servicing and repair procedures can increase the
risk of personal injury and death by preventing a safety belt
pretensioner from activating when needed or activating it unex­
pectedly:
Controls and equip­ ment Safety first Vehicle operation
& WARNING
(continued)
• The belt pretensioner system can be activated only once. If belt
pretensioners have been activated, the system must be replaced.
• Never repair, adjust, or change any parts of the safety belt
system.
• Safety belt systems including safety belt pretensioners cannot
be repaired. Special procedures are required for removal, installa ­
tion and disposal of this system.
• For any work on the safety belt system, we strongly recom ­
mend that you see your authorized Audi dealer or qualified tech­
nician who has an Audi approved repair manual, training and
special equipment necessary.
~ For the sake of the environment
Undeployed airbag modules and pretensioners might be classified as
Perchlorate Material -special handling may apply, see
www.dtsc.ca .gov/hazardouswaste/perchlorate. When the vehicle or
parts of the restraint system including air bag modu les safety belts
with pretensioners are scrapped, all app licab le laws and regu lations
must be observed. Your authorized Audi dealer is familiar with these
requirements and we recommend that you have your dealer perform

& WARNING
Sitting too close to the steering wheel or instrument panel will
decrease the effectiveness of the airbags and will increase the r isk
of personal injury in a collision.
• Never sit closer than 10 inches (25 cm ) to the steer ing wheel or
instrument panel.
• If you cannot sit more than 10 inches (25 cm ) from the
steering wheel, investigate whether adaptive equipment may be
available to help you reach the pedals and increase your seating
distance from the steering wheel.
• If you are unrestrained, leaning forward, sitting sideways or
out of po sition 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 .
Controls and equip­ ment Safety first Vehicle operation
& WARNING
(co ntinued )

everybody in your vehicle 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 airbag when it inflates .
• Although the Advanced Airbag System in your vehicle is
designed to turn 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 conditions is
impossible in all conceivable situations that may happen during
the useful life of your vehicle.
• The Advanced Airbag Sy stem 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
pas senger seat and the other condition s for airbag deployment
are met.
