With the front seats, the height adjustment
of the seat can also be used to adjust the po­
sition of the safety belts.
Improperly worn safety belts
Incorrectly positioned safety belts can cause se­
vere injuries.
Wearing safety belts improperly can cause seri­
ous injury or death. Safety belts can only work
when they are correctly pos itioned on the body .
Improper seating positions reduce the effect ive­
n ess of safety be lts and will even inc rease the
ris k of injury and death by mov ing the safety bel t
to cr it ica l areas of the body. Imp roper seating
positions also increase the risk of serious inj ury
and death when an airbag deploys and strikes an
occ upant who is not in the co rrect seat ing posi­
tion. A driver is respons ible for the safety of all
vehicle occupants and espec ia lly for children.
Therefore:
.. Never permit anyone to ass ume an incorrect
s itting position in the veh icle wh ile traveling
¢ &, .
A WARNING
Improperly worn safety belts i ncrease the risk
of serious personal injury and death wheneve r
a vehicle is be ing used.
S afet y be lts
- Always make sure that all veh icle occupants
are correctly restrained and stay in a correct
seating position whenever the vehicle is be­
ing used.
- Always read and heed all WARNINGS and
other important informat ion¢

versible tens ion ing f unct ion in m inor collisions.
Pyrotechnic safety belt pretens ioners
All safety belts except for the safety belt in the
center seat position of the rea r seat are equipped
with safety belt pretensioners. The sys tem is acti­
va ted by sensors in front, side and rear-end co lli­
s ions of great severity and in a rollover. Th is

on page 252.
Taking up the slack helps to re­
duce forward occupant movement during a co lli­
s io n.
(!) Tips
The pyrotechn ic safety belt pretensioners can
on ly be act ivated once.
- The safety belt pretensione rs do not deploy
in minor frontal, side and rear-end colli­
sions.
- When the pyrotechn ic safety belt preten­
sioners are activated, a fine dust is released.
Th is is normal and is not caused by a fire in
the vehicle .
- The relevant safety requirements must be
observed when the vehicle or components
of the sys tem are scrapped. An authorized

to pass on the information to you.
- Be sure to observe all safety, environmental
and other regulations if the vehicle or indi­
vidual parts of the system, particularly the
safety belt or airbag, are to be disposed . We
recommend you have your authorized Audi
dealer perform this service for you.
Service and disposal of safety belt preten­
sioner
The safety belt pretensioners are parts of the
safety belts on your Audi. Installing, removing,
servicing or repairing of belt pretensioners can
damage the safety belt system and prevent it
from working correctly in a collision.
There are some important things you have to
know to make sure that the effectiveness of the
system will not be impaired and that discarded
components do not cause injury or pollute the
environment.
A WARNING
Improper care, servicing and repair proce­
dures can increase the risk of personal injury
and death by preventing a safety belt preten­
sioner from activating when needed or acti­
vating it unexpectedly :
- The pyrotechnic safety belt pretensioners
can only be activated once.
If pyrotechnic
safety belt pretensioners have been activat­
ed, 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, instal­
lation and disposal of this system.
- For any work on the safety belt system, we
strongly recommend that you see your au­
thorized Audi dealer or qualified technician
who has an Audi approved repair manual,
training and special equipment necessary.

Repair , care and disposal of the airbags
Parts of the a irbag system are installed at many
different places on your Audi. Installing, remov­ ing, servic ing or repa iring a part in an area of the
ve hicle can damage a part of an airbag system
and prevent that system from working properly
i n a collision .
There are some important things you have to
know to make sure that the effectiveness of the
system w ill not be impaired and that discarded
components do not cause injury or pollute the
env ironment.
A WARNING
Improper care, serv icing and repai r proce­
dures can increase the r is k of personal injury
and death by preventing an airbag from de­
ploying when needed or dep loying an airbag
unexpectedly:
-
- Never cover, obstruct, or change the stee r­
ing wheel horn pad or airbag cover or the in­
strument pane l or modify them in any way.
268
- Never attach any objects s uch as c upholders
or telephone mountings to the surfaces cov­
ering the a irbag un its.
- For cleaning the horn pad or instrument
panel, use only a soft, dry cloth or one mois­
tened w ith plain water. Solvents or cleaners
could damage the airbag cover or change
the st iffness or strength of the material so
that the airbag canno t deploy and p rotect
properly.
- Never repair, adjust , or change any parts of
the airbag system.
- All work on the steering wheel, inst rument
panel, front seats or e lectr ica l system ( in­
cluding the installation of a udio eq uipment,
cellular telephones and C B radios, etc.)
m ust be perfo rmed by a qualified techn ician
who has the training and specia l equipment
necessary.
- For any work on the airbag system, we strong ly recommend that you see your au­
thorized A udi dealer or qualified workshop.
- Never modify the front b umper or parts of
the vehicle body.
- Always make sure that the side a irbag can
inflate w ithout interference:
- Never install seat covers or replacement
upholstery over the front seatbacks that
have not been specifically approved by
A udi.
- Never use additional seat c ushions that
cover the areas where the side airbags in­
flate.
- Damage to the orig inal seat cove rs or to
the seam in the area of the s ide airbag
module mus t always be repaired immedi­
ate ly by an autho riz ed Au di dealer.
- The a irbag system can deploy on ly once. Af­
ter an airbag h as been deployed, i t m ust be
repla ced with new replacement parts de­
signed and approved espec ia lly for your
Audi model version . Replacement of com­
plete airbag systems or airbag components
must be perfo rmed by qua lified workshops
only. Make su re that any airbag service ac­
tion is entered in your A udi Warranty

Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag System
performs in a crash . For example, using tire-r im
comb inat ions not approved by Audi, lowering the
ve hicl e, chang ing the stiffness of the suspens io n,
in clud ing the spr ings, suspens ion str uts, shock
absorbers et c. can change the forces that are
measured by the airbag sensors and sent to the
e lectronic contro l unit. Some suspension changes
can, for example, increase the force levels meas­
ured by the sensors and make the airbag system
deploy in crashes in wh ich it would not deploy if
the changes had not been made. Other ki nds of
changes may reduce the fo rce levels meas ured by
the sensors and prevent the airbag from deploy­
in g when i t should .
Airbag sys tem
A WARNING
-Changing the vehicle's suspension including
use of unapproved tire-rim combinations can
change Advanced Airbag performance and in­
crease the risk of serious persona l injury in a
crash.
- Never install suspension components that
do not have the same pe rformance charac­
teristics as the components o rigina lly ins tal­
led on your vehicle.
- Never use tire-rim combinations t hat have
not been approved by Audi.
