Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag Sys-
tem performs in a crash. For example, us ing
tire-r im combinations not app roved by Audi,
lowering the vehicle, changing the stiffness of
the suspension, including the sp rings, s uspen-
sion struts, shock absorbers etc. can change
the forces that are measured by the airbag
sensors and sent to the electronic control
un it. Some suspension changes can, for exam-
ple, increase the force levels measured by the
sensors and make the airbag system deploy in
crashes in wh ich it would not dep loy if the
changes had not been made . Other kinds of
changes may reduce the force levels meas -
ured by the sensors and prevent t he a irbag
from deploying when it shou ld.
The senso rs in the safety belt buckle fo r the
driver an d front passenger sea t tell the elec -
tronic control module if the safety belt is
latched or not . If the safety belt is being used,
the front airbag will dep loy at a slightly high-
er rate of vehicle deceleration than if the safe -
ty belt is not being used. Therefore, in a par-
ticular collision, it is poss ible that an airbag
will not deploy at a seating position where the
safety belt is being use d but will inflate at the
position whe re the safety belt is not being
used. It is important t ha t nothing interfe re
wit h the safety belt buckles so t hat t he sen -
sors can send t he correct information abo ut
safety belt use to the electronic contro l unit.
.&_ WARNING
Changing the vehicle 's s uspension includ-
ing use of unapproved tire-rim combina-
tions can change Advanced Airbag pe r-
formance and increase the risk of ser ious
personal injury in a crash.
- Never install suspens ion components
that do not have the same performance
A irba g sy stem 175
characteristics as the components origi-
na lly installed on your vehicle .
- Never use tire-rim com binations that
have not been approved by Audi.
.&_ WARNING
=
-
Items stored between the safety be lt
buckle and the center console can cause
the sens ors in t he buckle to send the
wrong information to the e lectronic con -
trol module and prevent the Advanced Air-
bag Syst em from wo rking properly.
- Always ma ke sure that nothing can int er-
fe re with the safety belt buckles and that
they are not obstructed.
Side airbags
Description of side airbags
The airbag system can provide supplemental
protection to properly restrained occupants.
Fig. 17 9 Side airbag loca tion in the driver's seat
The side airbags are located in the sides of the
front seat backrests¢ fig. 179 and the rea r
backrest faci ng the doors . They are ident ified
by the word "AIRBAG".
The side airbag system basically consists of :
- the electronic control modu le and external
side impact sensors
- t he two airbags located in the sides of t he
front backrests and the two a irbags* located
in the rear backrest
- the airbag warn ing light in the instrument
cluster .
The airbag system is mo nitored e lect ronically
t o make cert ain tha t it is function ing pro perly
