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.

backs .
A tether is a stra ight or V-shaped strap tha t at­
taches the top part of a child restra int to speci al
anchorage points in the vehicle.
The purpose of the tether is to red uce the for­

in order to help red uce the risk of head injury
that could be caused by strik ing the vehicle inte­
rior.
Forward fac ing child restraints manufactured af ­
ter September 1, 1999, are required by U.S. fed­
eral regulations to comply with new child head
movement performance requirements. These
new perfo rmance requirements make a tethe r
necessary on most new child safety seats.

increase the r isk of injury and death in a
crash.
- Always follow the instructions provided by
the manufacturer of the child restra int you
intend to install in your Audi .

clud ing tether anchors) can lead to inj ury in
a collision . The ancho rs are designed to
withs tand only those loads imposed by cor­
rectly fitted child restra ints.
- Never mount two chi ld restraint systems on
one LATCH lower a nchor po int.
