Third Row Seat — Two or Three Passenger
For vehicles with a two passenger third row seat,
there is one top tether anchor located at the
bottom rear of the seat cushion that can be used
for the rear driver side seating position in the
third row. Never install two top tethers using the
same top tether anchor.
For vehicles with a three passenger third row seat,
there is one top tether anchor located at the
bottom rear of the seat cushion that can be used
for either the third row center or driver side
seating position. Never install two top tethers using
the same top tether anchor.
Do not secure a child restraint in the right front
passenger position or the third row passenger side
seating position if your vehicle has a third row
seat, 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 these positions.
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 74
for additional information.
