— 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
#; 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 ¥,
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.
How the Advanced Airbag System
oYpa) Ma Cel (Laas
The front Advanced Airbag System and the side
airbags supplement the protection offered by the
front
three-point safety belts to help reduce the
risk of injury in a wide range of accident and crash
situations. Be sure to read the important infor-
mation about safety and heed the WARNINGS in
this chapter.

Important safety instructions on
monitoring the Advanced Airbag System
ZA WARNING
— If the status of the Advanced Airbag System
has changed while the vehicle is moving, the
PASSENGER AIR BAG OFF #¥; ON ® light
blinks for about 5 seconds to catch the driv-
er's attention. If this happens, always stop
as soon as it is safe to do so and check the
steps described above.
— If the PASSENGER AIR BAG OFF %; light
does not go off when an adult who is not
very small is sitting on the front passenger
seat after taking the steps described above,
have the airbag system inspected by your
authorized Audi dealer before transporting
anyone on the front passenger seat.

ZA WARNING
An airbag system that is not functioning prop-
erly cannot provide supplemental protection
in a frontal crash.
— If the airbag indicator light > page 18
comes when the vehicle is being used, have
the system inspected immediately by your
authorized Audi dealer. It is possible that
the airbag will inflate when it is not sup-
posed to, or will not inflate when it should.

ZA\ WARNING
If the front airbag inflates, a child without a
child restraint, or in a rearward-facing child
safety seat, or in a forward-facing child re-
straint that has not been properly installed
will be seriously injured and can be killed.
— If you must install a rearward-facing child
seat on the front passenger seat because of
exceptional circumstances and the PASSEN-
GER AIR BAG OFF #¥; light does not appear
and stay on, have the airbag system inspect-
ed by your Audi dealer.

— Forward-facing child seats installed on the
front passenger seat may interfere with the
deployment of the airbag and cause serious
personal injury to the child.
— If exceptional circumstances require the use
of a forward-facing child restraint on the
front passenger's seat, the child's safety and
well-being require the following special pre-
cautions to be taken:
— Always make sure that the forward-facing
seat has been designed and certified by its
manufacturer for use on a front passenger
seat with a front and side airbag.
— Always carefully follow the manufacturer's
instructions provided with the child seat or
infant carrier.
— Never put the forward-facing child re-
straint up against or very near the instru-
ment panel.
— Always move the front passenger seat to
the highest position in the up and down
adjustment range and move it back to the
rearmost position in the seat's fore and aft
adjustment range, as far away from the
airbag as possible, before installing the
forward-facing child restraint.
— Always make sure that the safety belt up-
per anchorage is behind the child restraint
and not next to or in front of the child re-
straint so that the safety belt will be prop-
erly positioned.
— Always make sure that nothing prevents
the front passenger's seat from being
moved to the rearmost position in its fore
and aft adjustment range.
— Never place objects on the seat (such as a
laptop, CD player, electronic games device,
power inverter or seat heater for child
seats). These may influence the electrical

capacitance measured by the capacitive
passenger detection system and can also
fly around in an accident and cause serious
personal injury.
— Never place or use any electrical device
(such as a laptop, CD player, electronic
games device, power inverter or seat heat-
er for child seats) on the front passenger
seat if the device is connected to the 12-

> 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 219.
» 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. 163.

ZA\ 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.
