Second Row
For models with second row bucket seats, the top tether
anchors are located at the bottom rear of the seat
cushion for each position in the second row. Be sure to
use the anchor located nearest to the seating position
where the child restraint will be placed.
Bucket
Third Row
For SUV models with third row seating, the top tether
anchor is located at the bottom rear of the seat cushion
for the passenger side seating position in the third row.
Do not secure a child restraint in a position without a
top tether anchor 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.
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 2 49 for additional
information.
