Locations
Second Row

i
(Top Tether Anchor):
Seating positions with top
tether anchors.
j
(Lower Anchor):
Seating positions with
two lower anchors.
For five-passenger vehicles, the labels are located
above a flap, at the base of the seatback, in the rear
outside seating positions. The anchors are located under
the flap. In order to get to the anchors you will need
to pull the strap at the center of the seat where the seat
cushion meets the seatback. This will allow you to
fold the seat cushion up and out of the way. Lift the flap
to expose the anchors and then lower the seat
cushion. Be sure the cushion is locked into place.
To assist you in locating the
lower anchors, each
seating position with lower
anchors has two labels,
near the crease between
the seatback and the seat
cushion, showing where
the anchors are located.
