seats or infant carriers on the front pas­
senger seat. A child will be seriously in­
jured and can be killed when the passen­ ger airbag inflates.

safety seat or infant carrier with great
force and will smash the child safety seat
and child against the backrest, center
armrest, door or roof.
- Always install rear-facing child safety
seats or infant carriers on the rear seat.

A tether is a straight or V -sha ped strap that
attaches the top part of a child res traint to
specia l anchorage poi nts in the veh icle.
T he purpose of the tether is to reduce the for­
ward movement of the c hild restra int in a
crash, in o rder to help reduce the r isk of head
i n jury that could be caused by striki ng the ve­
hi cle inter io r.
Forward facing child restraints manufactured
after September 1, 1999 , are required by U .S .
federal regulations to comp ly with new c hild
h ead movement perform ance requirements.
These new per formance requ irements make a
tether necessary on most new child safety
seats.
A WARNING
Improper insta llation of chi ld restraints
w ill increase the risk of injury and death in
a crash.
- Always fo llow the instructions prov ided
by the manufacturer of the ch ild re­
straint you intend to install in your Audi.
