Description
Lower anchorages
Fig. 123 Rear seats:
lower anchorage
bracket locations
The lower anchorage attachment points are located between the
rear seatback and rear seat cushion~ fig. 123.
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.
Safety first
Child Safety
& WARNING (continued)
• 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.

The lower anchorage attachment points are located on the
rear seats between the seatback and the seat cushion .
Special gu idance fixtures increase the convenience of the
lower anchorages and help protect the seat material from
possible damage when installing ch ild restraints that have
rigid lower anchorages and not straps with hooks.
Installing the guidance fixtures
- Push down on the seat cushion so that the lower anchor­
ages are visible.
- Hold the guidance fixture with the part number facing
downward and push it in the direction of the arrow onto
the anchorage =>
page 174, fig. 125.

-Remove the child restraint according the child restraint
manufacturer's instructions.
- 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 plac e. 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.
• 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
• Remov e the guidance fixtur es before folding th e rear se atback 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 J 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.•

Improper installation of child restraints will increase the risk of
injury in a crash .
• Never attach a child safety seat tether strap to a tie-down hook
in the luggage compartment.
• Never secure or attach any luggage or other items to the LATCH
lower anchorages or to the tether.
• 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 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 .•
Using tethers on rear-facing child restraint
systems
Curr ently, few r ear -facing chi ld restraint systems come with a tether.

Safety first
Child Safety
& WARNING
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 ch ild safety seat and
child against the backrest , or door .
• A tight tether or other 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.
• If you must install a rearward facing child safety seat on the
front passenger seat because of exceptional circumstances and
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 posit ion and have the airbag system inspected by your
Audi dealer . •
