Chevrolet 2005 Impala Owner's Manual page 52

The top tether anchors are located under the trim
covers on the rear seatback filler panel behind each
head restraint. Be sure to use an anchor located on the
same side of the vehicle as the seating position
where the child restraint will be placed.
Do not secure a child restraint in the right front
passenger's position if a national or local law requires
that the top tether be attached, or if the instructions that
come with the child restraint say that the top tether
must be attached. There is no place to attach the top
tether in this position.

Accident statistics show that children are safer if they
are restrained in the rear rather than the front seat. See
Where to Put the Restraint on page 1-42 for additional
information.
Securing a Child Restraint Designed for
the LATCH System
CAUTION:
{
If a LATCH-type child restraint is not attached to
anchors, the restraint will not be able to protect
the child correctly. In a crash, the child could be
seriously injured or killed. Make sure that a
LATCH-type child restraint is properly installed
using the anchors, or use the vehicle's safety
belts to secure the restraint, following the
instructions that came with that restraint, and
also the instructions in this manual.
