Airbag system

entered in your Audi Warranty & Mainte-
nance booklet under AIRBAG REPLACEMENT
RECORD.
— Applies to plug-in hybrid* vehicles: In the
event of a collision where the airbags de-
ploy, the electrical connection to the high
voltage battery is automatically disconnect-
ed. This prevents a short circuit.
Other things that can affect Advanced
ONY em ace lie
Changing the vehicle's suspension system can
change the way that the Advanced Airbag System
performs in a crash. For example, using tire-rim
combinations not approved by Audi, lowering the
vehicle, changing the stiffness of the suspension,
including the springs, suspension struts, shock
absorbers etc. can change the forces that are
measured by the airbag sensors and sent to the
electronic control 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 which it would not deploy if
the changes had not been made. Other kinds of
changes may reduce the force levels measured by
the sensors and prevent the airbag from deploy-
ing when it should.

ZX, 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 personal injury ina
crash.
— Never install suspension components that
do not have the same performance charac-
teristics as the components originally instal-
led on your vehicle.
— Never use tire-rim combinations that have
not been approved by Audi.

Knee airbags
Pregl) aCe ola ACLs eh)
Applies to: vehicles with knee airbags
The knee airbag system can provide supplemen-
tal protection to properly restrained front seat
occupants.

Fig. 219 Driver's knee airbag
The driver knee airbag is in the instrument panel
underneath the steering wheel > fig. 219, the
airbag for the passenger is at about the same
height in the instrument panel underneath the
glove compartment.
The knee airbag offers additional protection to
the driver's and passenger's knees and upper and
lower thigh areas and supplements the protec-
tion provided by the safety belts.
If the front airbags deploy, the knee airbags also
deploy in frontal collisions when the deployment
threshold stored in the control unit is met
=> page 263, More important things to know
about front airbags.
In addition to their normal safety function, safe-
ty belts help keep the driver or front passenger in
position in a frontal collision so that the airbags
can provide supplemental protection.
The airbag system is not a substitute for your
safety belt. Rather, it is part of the overall occu-
pant restraint system in your vehicle. Always re-
member that the airbag system can only help to
protect you if you are wearing your safety belt
and wearing it properly. This is why you should al-
ways wear your safety belt, not just because the
law requires you to do so > page 245, General
notes.
