passenger de t ection system from accurate ly
measu ring the capacitance of t he ch ild safe-
ty seat and/or the perso n on the seat and
t hus kee p the Advanc ed Airbag Syst e m from
working properly .
- Never place or use any electrical device
(suc h as a laptop, CD player, electronic
games dev ice, power inverte r or seat heater
for child seats) on the front passenger seat
if the devi ce is conne cted to the 12-volt
socket o r the cigarette lighter socket. Such
devices can influence the capacitance regis -
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
passenge r seat and the child restraint man-
ufact urer 's instructions require the use of a
towel, foam cushion or something else to
properly pos ition the ch ild restraint, make
certain tha t the
PASSENGER AIR BAG OFF
ligh t comes on and stays on whenever the
child restraint is installed on t he front pas-
senger seat.
- If the PASSENGER AIR BAG OFF light does
not come on and st ay on, immedia t ely in-
st a ll child res t raint in a rea r se ating position
and have t he 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 togethe r with
the a irbag indicator light II (USA models)/
El (Canada models) in the instrument clus-
ter.
- If liquid is poo led on the seat, bu t has not
soa ked in, this may also keep the airbag sys-
tem from wo rking pro perly and ca use the
passenge r frontal airb a g to be enabled
(tu rned on), even though the re is a properly
Airbag sys t e m
installed child 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
turn off.
How the Advanced Airbag System
components work together
The front Advance d Airbag Syst em and the side
airbags supp lement the protection offered by the
front t hree-point safety be lts and the adjustable
head restraints * to help red uce the risk of inju ry
in a wide range of accident and crash situat ions.
Be sure to read the important information about
safety and heed the WARNINGS in this chapte r.
Deployment of the Advanced Airbag System and
the activation of the safety belt pretensioners de-
pend on the dece leration measured by the crash
senso rs and reg istered by the electronic contro l
unit . Crash severity depe nds on speed and dece l-
eration as well as the mass and stiffness of the
vehicle or object involved in the cras h.
On the passenger side, regard less of safety be lt
use, the front passenge r frontal airbag will be
tu rned off if the e lectr ical capacitance measured
by the capacitive passenge r detect ion syst em on
t he fron t passenger se at is less th a n the a mou nt
programmed in t he e lectronic contro l unit . The
front passenge r frontal airbag 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 chi ld 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 and stays o n to tell you when the front Ad-
vanced Airbag Syst em on t he passenger side has
been tur ned off
q page 154 .
To reduce the risk of injury when an air bag in-
flates, always wear safety belts properly.
- If you are un res t ra ined, leaning forwar d, sit -
ting sideways or out of position in any way,
your risk of injury is much higher .
