Vehicle care Technical data

-Airbag system ------=-~-----------------------------------
& WARNING (conti nued)
• Always make sure that the side a irbag can inflate without
interference :
- Never in stall seat covers or replacement uphol stery over the
front seatbacks that have not been specifically approved by
Audi .
- Never use addit ional se at cushions that cover the areas
where the side ai rbags inflate.
- Damage to the or iginal seat covers or to the seam in the area
of the side airbag module must always be repaired immedi­
ately by an author ized Audi dealer.
• The airbag system can be activated only on ce. After an airbag
has inflated, it must be replaced by an authorized Audi dealer or
qualified technician who has the techni cal information, t raining
and special equipment necessary.
• The airbag sy stem can be deploy ed only once. After an airbag
has been dep loyed , it must be replaced with new replacement
parts designed and approved e specially for your Audi model
version. Replacement of complete airbag systems or a irbag
components must be performed by qualified workshops onl y.
Make sure that any airbag service action is entered in your Audi
Warranty
& Maintenance booklet under AIRBAG REPLACEMENT
RECORD .
• In accidents when an airbag is deployed, the vehicle battery
separates the alternator and the starter from the vehicle electrical
system for safety reason s with a pyrotechnic circuit interrupte r.
- Work on the pyrotechnic circuit interrupter must only be
performed by a qualified dealer -risk of an accident!
- If the vehicle or the circuit interrupter is sc rapped , all appli ­
cable safety precautions must be followed.
W For the sake of the environment
Un deployed ai rbag modu les and p retensione rs might be class ified as
Perch lorate Materia l -special handling may ap ply, see
www.dts c.ca.gov/ha za rdouswas te/pe rchlorate. When the vehicle or
parts of the restraint system includ ing a irbag modu les safety belts
w it h pretensioners are s crapped, all appli cable laws and regula tions
must be observed. Your author ized Aud i dealer is familiar with these
req uiremen ts and we recommen d that you have your dealer perfo rm
this serv ice for you. •
Other things that can affect Advanced
Airbag performance
Chang ing the vehicle's suspension system can change the way that
t h e Advan ced Airbag System pe rforms in a cr ash . For e xamp le, usi ng
tire-rim combinations not app roved by Audi, lowering the vehicle,
c hang ing the stiffness o f th e suspension, incl uding the sp rings,
suspension struts, shock absorbers etc. can change the forces that
are meas ure d by the a irba g sensors and sent to the ele ct ronic contro l
unit . Some suspension changes can, fo r exam ple, increase the force
levels measured by the senso rs and make the airbag system deploy in
crashes in which i t would not deploy if the changes had no t been
ma de . Other kinds of changes may reduce the force levels meas ured
by the sensors and p revent the airbag from dep loying when it should.
T he sensors in the safety belt b uckle for the drive r and front
p as senge r se at tell the e lectroni c cont rol mo dule if the sa fe ty belt is
latched or not . If the safety belt is being used, t he front a irbag w ill
dep loy a t a s lightly h igher r ate o f vehicle decele ration t han if t he
safety belt is not be ing used . Therefo re, in a par ticular collis io n, it is
possible that an a irba g w ill not dep loy at a seating position where the
safety belt is being used but w ill inflate at the posit ion where the
safety belt is not be ing use d. It is im portant that nothing interfere
w it h t he safety belt bu ckles so that the sensors can se nd the co rrect
info rmation about safety be lt use to the electronic contro l unit.
