Airbag system



Advanced Airbag System from functioning
properly.
— Repairs to the front passenger seat must be
performed by qualified and properly trained
workshop personnel.
— Never remove the front passenger or driver
seat from the vehicle.
— Never remove the upholstery from the front
passenger Seat.
— Never disassemble or remove parts from the
seat or disconnect wires from it.
— Never carry sharp objects in your pockets or
put them on the seat. The capacitive passen-
ger detection mat in the front passenger
seat will not function properly if it is punc-
tured.
— Never carry things on your lap or carry ob-
jects on the front passenger seat. Such ob-
jects can
influence the capacitance regis-
tered by the capacitive passenger detection
system, so that incorrect information is pro-
vided to the airbag control unit.
— Never store items under the front passenger
seat. Parts of the Advanced Airbag System
under the passenger seat could be dam-
aged, preventing them and the airbag sys-
tem from working properly.
— Never place seat covers or replacement up-
holstery that have not been specifically ap-
proved by Audi on the front seats.
— Seat covers can prevent the Advanced Airbag
System from recognizing child restraints or
occupants on the front passenger seat and
prevent the side airbag in the seat backrest
from deploying properly.
— If a seat heater has been retrofitted or oth-
erwise added to the front passenger seat,
never install any child restraint system on
this seat.
— Never use cushions, pillows, blankets, or
similar items on the front passenger seat.
The additional layers prevent the capacitive
passenger detection system from accurately
measuring the capacitance of the child 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 device, 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 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
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 child restraint, make
certain that the PASSENGER AIR BAG OFF
3%; light comes on and stays on whenever
the child restraint is installed on the front
passenger Seat.
— If the PASSENGER AIR BAG OFF #; light
does not come on and stay on, have the air-
bag system inspected by your Audi dealer.



ZA 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, deacti-
vate the passenger frontal airbag. If this
happens, the PASSENGER AIR BAG OFF 3;
light will come on and stay on together with
the airbag indicator light ka in the instru-
ment cluster.
— If liquid is pooled on the seat, but has not
soaked in, this may also keep the airbag sys-
tem from working properly and cause the
passenger frontal airbag to be enabled
(turned on), even though there is a properly
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 frontal airbag is turned on,
the PASSENGER AIR BAG OFF #; light will
turn off.

is sitting in a proper seating position on the front
passenger seat. If the PASSENGER AIR BAG OFF
#; light comes on and stays on while driving, un-
der these circumstances, make sure that:
— the adult on the front passenger seat is proper-
ly seated on the center of the seat cushion with
his or her back up against the backrest and the
backrest is not reclined,
— the adult is not taking weight off the seat by
holding on to the passenger assist handle
above the front passenger door or supporting
their weight on the armrest,
— the safety belt is being properly worn and that
there is not a lot of slack in the safety belt web-
bing,
— there are no aftermarket seat covers or cush-
ions or other things (such as blankets) on the
front passenger seat that might cause the ca-
pacitive passenger detection system to miscal-
culate electrical capacitance.

Babies and infants up to about one year old and
20 lbs or 9 kg need special rearward-facing child
restraints that support the back, neck and head
in.acrash.

Fig. 168 Rearward-facing infant seat, properly installed on
the passenger seat
> When using the vehicle safety belt to install a
child safety seat, you must first activate the
convertible locking retractor on the safety belt
to prevent the child safety seat from moving
=> page 220.
> Push the child safety seat down with your full
weight to get the safety belt really tight so that
the seat cannot move forward and sideways
more than 1 in (2.5 cm).
Infants up to about one year (20 lbs or 9 kg) are
best protected in special infant carriers and child
safety seats designed for their age group. Many
experts believe that infants and small children
should ride only in special restraints in which the
child faces the back of the vehicle. These infant
seats support the baby's back, neck and head ina
crash > fig. 168.

A WARNING
Not using a child safety seat, using the wrong
child safety seat or improperly installing a
child restraint increases the risk of serious
personal injury and death in a crash.
— Never install a rear-facing child restraint in
the forward-facing direction. Such restraints
are designed for the special needs of infants
and
very small children and cannot protect
them properly if the seat is forward-facing.
