Child Safety -
---------------''----
& 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

activate the convertible locking retractor:
Controls and equip­
ment Safety first
Vehicle operation
-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 pul ling 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

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".
~

___ C_h_ i_ld _ S_ a_ f_ e_ t-= y'-------------------------------------------------
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.
Fig . 244 Schematic
overview: LATCH
anchorage point loca­
tions
The illustration =:> fig. 244 shows the seating locations in your
vehicle which are equipped with the lower universal anchorages system. •
Description
The lower anchorage positions are marked for quick
locating.

Attachment locator markers for lower anchorages
Circular locator buttons on the rear seatback indicate the lower
anchorage locations on the rear seating
positions=> fig . 245.
Lower anchorages
The lower anchorage attachment points are located between the
rear seatback and rear seat
cushion =:> fig. 246.
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 re member that the lower anchorage points are only intended
for installation and attachment of chi ld 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 be lts .
& 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
=> page 243 , "Child
Safety".•

- Push down on the seat cushion so that the lower anchor ­
ages are visible.
- Pull off the guidance fixtures from the lower anchorages.
-Always remove the guidance fixtures and keep them in a
safe place when not in use.
You may find it easier to install child restraints equipped with hooks
attached to straps without the guidance fixtures in place . If this is
the case, remove the guidance fixtures by pulling them off the
anchorages. However, the guidance fixtures can help you to locate
the
LATCH anchorages.
& WARNING
Improper use of tether anchorages or lower anchorages can cause
serious personal injury in a crash.
• Always carefully follow the child restraint manufacturer's
instructions for proper installation and use of child restraint
systems.
& WARNING (continued)
• Never use the LATCH or tether anchorages to attach safety
belts or other kinds of occupant restraints.
• Child restraint tether attachments and lower attachments are
only designed to secure a child restraint that has been equipped
to use these anchorages.
• Tether anchorages and lower anchorages are designed to with­
stand only those loads imposed by correctly fitted child restraints.
Under no circumstances can they be used safely for adult or child
safety belts or harnesses.
• Never mount more than one child restraint to a single tether or
to a lower anchorage point. Attaching two child restraints to a
single anchorage point can cause the anchorage to fail and cause
serious personal injury in a crash.
0 Note
• Remove the guidance fixtures before folding the rear seatback to
prevent damaging the seat cushion.
• If you leave the guidance fixtures installed for several days, they
could leave a mark on the upholstery on the seat cushion and back­
rest in the area that the guidance fixtures were installed. The uphol ­
stery would also be permanently stretched around the guidance
fixtures . This applies especially to leather seats.
[ i] Tips
• Always remove the guidance fixtures when not in use .
• Please keep the guidance fixtures in a safe place with the vehicle
when not in use. •
