Child safety
-Always make sure the forward-facing seat
has been designed and certified by its man­
ufacturer for use on a front seat with a pas­
senger front and side airbag.
- Never put the forward-facing child restraint
up, against or very near the instrument pan­
el.
- Always move the passenger seat into its
rearmost position in the seat's fore and aft
adjustment range, as far away from the air­
bag as possible before installing the for­
ward-facing child restraint. The backrest
must be adjusted to an upright position.
- Make sure that the
PASSENGER AIR BAG
OFF
light comes on and stays on all the time
whenever the ignition is switched on.
_&. WARNING
Rearward-facing child restraints:
- A child in a rearward-facing child safety seat
installed on the front passenger seat will be
seriously injured and can be killed if the
front airbag inflates -even with an Ad­
vanced Airbag System.
- The inflating airbag will hit the child safety
seat or infant carrier with great force and
will smash the child safety seat and child
against the backrest, center armrest, door
or roof.
- Always be especially careful if you must in­
stall a rearward facing child safety seat on
the front passenger seat in exceptional cir­
cumstances.
- Make sure that the
PASSENGER AIR BAG
OFF
light comes on and stays on all the time
whenever the ignition is switched on .
- If the
PASSENGER AIR BAG OFF light does
not come on and stay on, immediately in­
stall the rear-facing child safety seat in a rear seating position and have the airbag
system inspected by your Audi dealer .

child restraint.
Always heed the child safety seat manufacturer 's
instructions when installing a child restrain t in
your vehicle . To activate the convertible locking
retractor:
.. Place the child restraint on a seat, preferably
on the rear seat.
.. Slowly pull the belt
all the way out .
.. Route it around or through the child restraint
belt path
~ ,&. .
.. Push the child safety seat down with your full
weight to get the safety belt really tight.
.. Insert the belt tongue into the buckle for that
seating position.
.. Guide the safety belt back into the retractor un­
til the belt lies flat and snug on the child safety
seat.
.. You should hear a "clicking" noise as the belt
winds back into the inertia reel. Test the con ­
vertible locking retractor by pulling on the belt.
You should no longer be able to pull the belt
out of the retractor. The convertible locking re­
tractor is now activated.
.. Make sure that the red release button is facing

unbuckled quickly.
.. Pull on the belt to make sure the safety belt is
properly tight and fastened so that the seat
cannot move forward or sideways more than
one inch (2 .5 cm) .
_&. WARNING
Using the wrong child restraint or an improp­
erly installed child restraint can cause serious
personal injury or death in a crash.
- Always make sure that the safety belt re­
tractor is locked when installing a child
safety seat. An unlocked safety belt retrac­
tor cannot hold the child safety seat in place
during normal driving or in a crash.
- Always buckle the child safety seat firmly in place even if a child is not sitting in it. A
loose child safety seat can fly around during
a sudden stop or in a crash.

-Always make sure the seat backrest to which
the child restraint is installed is in an up­
right position and securely latched into
place and cannot fold forward. Otherwise,
the seatback with the child safety seat at­
tached to it could f ly forward in the event of

LATCH system (Lower
anchorages and tethers
for children)
Child Restraint System anchors and how
are they related to child safety
To provide a simpler and more practicab le way to
attach the child restraint on the vehicle seat,
Federal regulations require special lower ancho­
rages in vehicles and devices on new child re­
straints to attach to the vehicle anchorages .
In the United States, the combination of the
tether anchorages and the lower anchorages is
now generally called the LATCH system for
"Lower Anchorages and Tethers for Children". In
Canada, the terms "top tether" with "lower uni­
versa l anchorages" (or "lower universal anchor­
age bars") are used to descr ibe the system .
In other countries the term "ISOFIX" is used to
describe the lower anchorages .
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 req uirements. These
new performance requirements make a tether
necessary on most new ch ild seats.
Installing a child restraint that requires a top
tethe r without one can seriously impair the per­
formance of the child restraint and its ab ility to
protect the child in a collision. Installing a child
restra int that requi res a top tether without the
top tether may be a violation of state law.
Child restraint manufacturers offer LATCH lower
anchorages on their child seats w ith hook-on or ..,.

Child safety
push-on connectors attached to adjustable
straps.
I n addition to the LATCH lower anchorages, these
chi ld restraint systems usually require the use of
tether straps to he lp keep the child restraint
firm ly in place.
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 veh icle.
- Never install a child restraint without a properly attached top tether strap if the
child restraint manufacturer's instruct ions
requ ire the top tether strap to be used.
- Improper use of child restra int LATCH lower
anchorage points can lead to injury in a colli ­
s ion . The LATCH lower anchorage points are
designed to withstand on ly those loads im­
posed by cor rect ly fitted child restraints .
- Never mount two child restraint systems on
one LATCH lower anchorage point.
- Never secure or attach any luggage or other
item to the LATCH lower anchorages.

All child restra ints manufact ured after Septem­
ber 1 , 2002, must have lower anchorage attach -
ments for the
LATCH system. ..,.

Please remember that the lower anchorage
points are only intended for installation and at­
tachment of child restraints specifically cert ified
for use with
LATCH lower anchorages. Child re­
straints that are not equipped with the lower an­
chorage attachments can still be installed in
compliance w ith the child restra int manufactur­
er 's instructions on using vehicle safety belts .
.8, WARNING
Improper use of LATCH lower anchorages can
cause serious personal injury in an accident.
- Always caref ully follow the child restra ints
