install a forward or rearward-facing child re­
straint on the front passenger's seat in excep­
tional situations:
- Whenever a forward or rearward-facing
child restraint is installed on the front pas ­
senger seat, the
PASSENGER AIR BAG OFF
light must come on and stay on whenever
the ignition is switched on.
- If the PASSENGER AI R BAG OFF light does
not come on and stay on , perform the

- Improper installation of chi ld restraints can
reduce their effectiveness or even prevent
them from providing any protection .
- An improper ly installed chi ld restraint can
interfere with the airbag as it deploys and
seriously injure or even kill the child.
- Always carefully follow the manufacturer's
instructions provided with the child safety
seat or carrier.
- Never place additional items on the seat
that can increase the total weight registered by the weight-sensing mat and can cause in­
jury in a crash .

ufacturer for use on a front seat with a pas­
senger front and side a irbag .
- Never put the forward-facing child restraint

-
justment range and move it back to the
rearmost posit ion in the seat's fore and aft
adjustment range, as far away from the a ir­
bag as poss ible, before install ing the for­
ward-facing child restraint .
- Always make sure that the safety belt upper
anchorage is behind the ch ild restraint and
not next to or in front of the child restraint
so that the safety be lt will be properly posi­

A WARNING
Rearward-facing chi ld restraints:
- A child in a rearward-fac ing ch ild safety seat
installed on the front passenger seat will be
serious ly injured and can be killed if the
front airbag inflates -even with an Ad ­
vanced Airbag System.
- The inflating airbag will h it the ch ild safety

aga inst the backrest, center armrest, door
or roof.
- Always be especially carefu l if you must in­
stall a rearward facing child safety seat on
the front passenger seat in exceptiona l cir­
cumstances .
- A t ight tether strap on a rearward-facing
child restraint attached to the front passen­
ger seat can put too much pressure on the
weight-mat in the seat and reg ister a heav i­
er weight in the Advanced Airbag System .
The heavier weight reg istered can make the
system work as though an ad ult were on the
seat and deploy the Advanced A irbag when
it must be suppressed causing serious or
even fata l injury to the child.
- Ma ke sure that the
PASSENGER AIR BAG

li ght comes on and stays on all the time

Child safety
that could be caused by striking the vehicle inte­
rior .
Forward facing child restraints manufactured af­
ter September 1, 1999, are required by U .S. fed­
eral regulations to comply with new child head
movement performance requirements. These
new performance requirements make a tether
necessary on most new child safety seats .
A WARNING
Improper installation of child restraints will
increase the risk of injury and death in a
crash.
- Always follow the instructions provided by
the manufacturer of the child restraint you intend to install in your Audi .
- Improper use of child restraint anchors (in ­
cluding tether anchors) can lead to injury in
a collision . The anchors are designed to
withstand only those loads imposed by cor­ rectly fitted child restraints.
- Never mount two child restraint systems on
one LATCH lower anchor point.
- Never attach two child restraint systems to
one tether strap or tether anchorage.
- Never attach a tether strap to a tie-down
hook in the luggage compartment.
- Never use child restraint tether anchorages
to secure safety belts or other kinds of occu­ pant restraints.
- Never secure or attach any luggage or other
items to the LATCH lower anchorages or to
the tether anchors.
- If a tether or other strap is used to attach a
child restraint to the front passenger seat,
make sure that it is not so tight, that it
causes the weight-sensing mat to measure
more weight than is actually on the seat.
- The heavier weight registered can make the
Advanced Airbag System work as though an
adult were on the seat and deploy the Ad­
vanced Airbag when it must be suppressed causing serious or even fatal injury to the
child.
- If you must install a rearward facing child
safety seat on the front passenger seat be­
cause of exceptional circumstances and the
