A irb a g syst em
manufacturer's instructions require the use
of a towel, foam cushion or something else
to properly position the child restraint,
make certain that the PASSENGER AIR BAG
OFF light comes on and stays on whenever
the child restraint is insta lled on the front
passenge r seat.
- If the PASSENGER AIR BAG OFF light does
not come on and stay on, immed iate ly in-
sta ll child restra int in a rear seating position
and have the a irbag system inspected by
your Audi dealer .
_&
WARNING
If the front passenger seat gets we t , dry it i m-
mediately .
- If liquid soaks into the front passenger sea t,
this can keep the airbag system from work -
ing properly and may, for instance, deacti-
vate the passenger frontal airbag. If th is
happens, the PASSENGER AIR BAG OFF
light will come on and stay on together with
the airbag indicator light
fl
in the inst ru-
ment cluster.
- If liquid is poo led on the seat, but has not
soaked in, this may a lso keep the airbag sys-
tem from work ing properly and cause the
passenge r frontal a irbag to be enab led
(turned on), even t ho ugh there is a properly
insta lled child restraint system on the sea t .
Wet towels or other wet things on the seat
cus hion can have the same effect . If the
front passenger fronta l airbag is turned on,
the PASSENGER AIR BAG OFF light light
will go out.
How the Advanced Airbag System
components work together
The fron t Advanced Airbag System and the side
a irbags supplement the prote ction offered by the
front three-point safety be lt s wit h pre tensioners
a nd load limiters and the adjustable head re-
straints * to he lp red uce the risk of injury in a
wide range of accident and crash situations . Be
sure to read the important informat ion about
safety and heed the WARNINGS in this chapter.

Deployment of the Advanced Airbag System and
the activation of the safety belt pretensioners de-
pend on the dece leration meas ured by the crash
sensors and registered by the electronic control
unit. Crash severity depends on speed and decel-
eration as we ll as the mass and stiffness of the
vehicle or object involved in the crash .
On the passenger side, regardless of safety belt
use, the front passenger frontal airbag will be
turned
off
if the electrical capacitance measured
by the capacitive passenge r detection system on
the front passenger seat is less than the amount
programmed in the electronic cont rol unit . The
fron t passenger frontal airbag will a lso be turned
off
if the capac itance meas ured by the syst em for
the front passenger seat equals that of an infant
of about one year of age in one of the child seats
that was used to certify the Advanced Airbag Sys-
tem under Federal Motor Vehicle Safety Standard
208. The PASSENGER AIR BAG OFF light comes
on a nd stays on to tell you when the front Ad-
vanced Airbag System on the passe nger side has
been t urned
