• Forward-facing child safety seats or infant carriers installed on
the front passenger's seat may interfere with the deployment of
the airbag and cause serious injury to the child.
• It is safer to install a forward-facing child safety seat on the rear
seat. • Always read and heed all WARNINGS whenever using a child
restrained in a vehicle is being used~
page 169. Special precau ­
tions apply when installing a child safety seat on the front

page 149, "Child restraints on the front seat -
some important things to know ".
L1}. WARNING
Always take special precautions if you must install a forward or
rearward -facing child restraint on the front passenger's seat in
exceptional situations:
• Whenever a forward or rearward -facing child restraint is
installed on the front passenger seat, the PASSENGER AIR BAG
OFF light must come on and stay on whenever the ignition is
switched on .
& WARNING (continued)
• If the PASSENGER AIR BAG OFF light does not come on and stay
on, perform the checks described~
page 158, "Monitoring the
Advanced Airbag System" .
• Take the child restraint off the front passenger seat and install
it properly at one of the rear seat positions if the PASSENGER AIR
BAG OFF light does not stay on whenever the ignition is switched
on .
• Improper installation of child restraints can reduce their effec ­
tiveness or even prevent them from providing any protection.
• An improperly installed child 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 injury in a crash.
L1}. WARNING
Forward-facing child restraints:
• Always make sure the forward -facing seat has been designed
and certified by its manufacturer for use on a front seat with a
passenger front and side airbag.
• Never put the forward-facing child restraint up , against or very
near the instrument panel .
• Always move the passenger seat into its 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 . 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 Advanced 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 arm rest, door or roof.
• Always be especially careful if you must install a rearward
facing child safety seat on the front passenger seat in exceptional
circumstances.
• A tight tether strap on a rearward-facing child restraint
attached to the front passenger seat can put too much pressure
on the weight-mat in the seat and register a heavier weight in the
Advanced Airbag System. The heavier weight registered can make
the system work as though an adult were on the seat and deploy
the Advanced Airbag when it must be suppressed causing serious
or even fatal injury to the child.
• 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 install the rear-facing child safety seat in a rear
seating position and have the airbag system inspected by your
authorized Audi dealer. •

Additional Information
What types of child restraint anchors are
available and how are they related to child
safety?
For years, child restraints have been installed using the safety belts
already present in every vehicle.
Since September 1, 1999, child restraint manufacturers have been
providing tether straps that attach the top of the child restraint to
the vehicles structure, on most of their forward-facing systems in order to comply with U .S . Federal regulations for child restraint
performance in a crash. Vehicle manufacturers are required to
phase -in tether anchorages for attachment of the tether strap in
their U.S. vehicles beginning September 1, 1999.
The combination of the tether anchorages and the lower anchor­
ages is now generally called the
LATCH system for "Lower Anchor
and Tether for Children".
~

Lower anchorages and tether for
children (LATCH)
Location
LATCH is the acronym for Lower Anchor and Tethers for
Children and designates a special child safety seat
restraint system. In Canada, the terms "top tether" with
"lower universal anchorages" (or "lower universal
anchorage bars") are used to describe the system.

Lower anchorages
The lower anchorage attachment points are located between the
rear seatback and rear seat cushion~ fig. 156.
Lower anchorages secure the child restraint in the seat without
using the vehicle's safety belts. Anchorages provide a secure and
easy-to-use attachment and minimize the possibility of improper
child restraint installation.
All child restraints manufactured after September 1, 2002, must
have lower anchorage attachments for the
LATCH system .
Please remember that the lower anchorage points are only intended
for installation and attachment of child restraints specifically certi­
fied for use with
LATCH lower anchorages. Child restraints that are
not equipped with the lower anchorage attachments can still be
installed in compliance with the child restraint manufacturer's
instructions on using vehicle safety belts. ...

& WARNING
Improper installation of child restraints will increase the risk of
injury in a crash.
• Always carefully follow the child restraints manufacturer's
instructions for proper installation of the child restraint and
proper use of the lower anchorages or safety belts in your vehicle .
• Never secure or attach any luggage or other items to the
LATCH
lower anchorages.
• Always read and heed the important information about child
restraints in this chapter and WARNINGS=:>
