Airb a g syste m
passenger detection system from accurately
measuring the capac itance of the ch ild safe-
ty seat and/or the person on the seat and
thus keep the Advanced Airbag System from
working properly .
- Never place or use any electrical device
(such as a laptop, CD player, electronic
games dev ice, power inverter or seat heater
for child seats) on the front passenger seat
if the device is connected to the 12-volt
socket or the cigarette lighter socket. Such
devices can influence the capacitance reg is-
tered by the capacitive passenger detection
system, so that incorrect information is pro-
vided to the airbag control unit.
- If you must use a child restraint on the front
passenger seat and the child restraint man-
ufacturer 's instructions require the use of a
towel, foam cushion or something else to
properly position the ch ild restraint, make
certain that the
PASSENGER AIR BAG OFF
light comes on and stays on whenever the
child restraint is installed on the front pas-
senger se at.
- If the PASSENGER AIR BAG OFF light does
not come on and stay on, immedia t ely in-
st al l child res t raint in a rear seating posi t ion
and have the airbag system inspected by
your Audi dealer.
A WARNING
If the front passenger seat gets wet, dry it im-
mediately .
- If liquid soaks into the front passenger seat,
this can keep the airbag system from work-
ing properly and may, for instance, deact i-
vate the passenger frontal airbag. If this
happens, the
PASSENGER AIR BAG OFF
light will come on and stay on together with
the a irbag indicator light min the instru-
ment cluster.
- If liquid is poo led on the seat, but has not
soa ked in, this may also keep the airbag sys-
tem from wo rking properly and cause the
passenge r frontal a irbag to be enabled
(tu rned on), even though there is a properly
installed chi ld restraint system on the seat.

Wet towels or other wet things on the seat
cushion can have the same effect. If the
front passenger fronta l airbag is turned on,
the PASSENGER AIR BAG OFF light will go
out .
How the Advanced Airbag System
components work together
The fro nt Advanced Airbag System and t he side
airbags supp lement t he protection offered by the
front t hree-point safety be lts and the adjustable
head restraints* to help red uce the risk of injury
in a wide range of accident and crash sit uations.
Be sure to read the important information 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 measured by the crash
sensors and registered by the electronic contro l
unit . Crash severity depends on speed and decel-
eration as well 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 electr ica l capacitance measured
by the capacitive passenge r detection system on
t he front passenger seat is less tha n the amount
prog rammed in t he elec t ron ic cont rol unit . The
front passenger frontal a irbag will also be turned
off if the capacitance measured by the system 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 Federa l 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 Syst em on t he passenger side has
been t ur ned off ~ page 281 .
A WARNING
To reduce t he risk of injury when an airbag in-
flates, always wea r safe ty belts prope rly.
- If you are un res t ra ined, lea ning forwar d, sit -
ting sideways or out of posi t ion in any way,
your ris k of injury is much higher.
