restraints and for the different models of the same kind of child
restraint offered by child restraint manufacturers.
The weight ranges for the individual types, makes and models of child restraints that the NHTSA has specified in the Safety Standard
together with the weight ranges of typical infants and typical 1 year­
old child have been stored in the control unit of the Advanced
Airbag System. When a child restraint is being used on the front passenger seat with a typical 1 year-old child, the Advanced Airbag
System compares the weight measured by the weight sensing mat
with the information stored in the electronic control unit.
The electronic control unit also registers the tension on the front
passenger safety belt. The tension on the safety belt for the front
passenger seat will be different for an adult who is properly using
the safety belt as compared to the tension on the belt when it is
used to attach a child restraint to the seat. The sensor below the
latch for the safety belt for the front seat passenger measures the
tension on the belt . The input from this sensor is then used with the
weight to "decide", whether there is a child restraint with a typical 1
year-old child on the front passenger seat and whether or not the airbag must be turned off.•
Child restraints and Advanced Airbags
Regardless of the child restraint that you use, make sure that it has
been certified to meet United States Federal Motor Vehicle Safety
Standards and has been certified by its manufacturer for use with
an airbag. Always be sure that the child restraint is properly
installed at one of the rear seating positions. If in exceptional
circumstances you must use it on the front passenger seat, carefully read all of the information on child safety and Advanced Airbags
and heed all of the applicable WARNINGS. Make certain that the
child restraint is correctly recognized by the weight -sensing mat
inside the front passenger seat, that the front passenger airbag is
turned off and that the airbag status is always correctly signaled by
the
PASSENGER AIR BAG OFF light. Many types and models of child restraints have been available over
the years, new models are introduced regularly incorporating new
and improved designs and older models are taken out of produc­
tion. Child restraints are not standardized. Child restraints of the
same type typically have different weights and sizes and different
'footprints,' the size and shape of the bottom of the child restraint
that sits on the seat, when they are installed on a vehicle seat. These
differences make it virtually impossible to certify compliance with
the requirements for advanced airbags with each and every child restraint that has ever been sold in the past or will be sold over the
course of the useful life of your vehicle.
For this reason, the United States National Highway Traffic Safety
Administration has published a list of specific type, makes and
models of child restraints that must be used to certify compliance
of the Advanced Airbag System in your vehicle with the suppression
requirements of Federal Motor Vehicle Safety Standard 208. These
child restraints are:
A. Car beds, manufactured on or after September 1,
2004:
• Cosco Dream Ride 02-719
B. Rear facing child restraint systems, manufactured
on or after September 1, 2004:

compliance has to be certified with or without the base).

Important safety instructions for using child
safety seats
Correct use of child safety seats substantially reduces the
risk of injury in an accident!
As the driver, you are responsible for the safety of every ­
body in the vehicle, especially children:
- Always use the right child safety seat for each child and
always use it properly :::>
page 215.
-Always carefully follow the child safety seat manufac­
turer's instructions on how to route the safety belt prop­
erly through the child safety 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 or sideways more than one inch (2.5 cm).
- If a strap or tether is being used to tie the child safety
seat 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.
Always remember: Even though your vehicle is equipped with an
Advanced Airbag system, all children, especially those 12 years and
younger, should always ride in the back seat properly restrained for
their age and size .

position of the passenger seat's fore and aft adjustment range,
and as far away from the airbag as possible before installing
the child restraint.
- 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.
- Always make sure that the backrest is in the upright posi­
tion.
• 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 collision.

& 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
Audi dealer. •
Activating the convertible locking retractor
Use the convertible locking retractor to secure a child
restraint.
Always heed the child safety seat manufacturer's instruc­
tions when installing a child restraint 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 until 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 convertible locking retractor
by pulling on the belt. You should no longer be able to
pull the belt out of the retractor. The convertible locking
retractor is now activated.
-Make sure that the red release button is facing away from
the child restraint so that it can be 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 improperly installed child
restraint can cause serious personal injury or death in a crash.
• Always make sure that the safety belt retractor is locked when
installing a child safety seat. An unlocked safety belt retractor
cannot hold the child safety seat in place during normal driving or
in a crash.
