Passenger Seating
Convertible Second Row Bucket
Seats
There are bucket seats with
armrests for two front passengers,
bucket seats with armrests for two
passengers in the second row, and a
bench seat for three passengers in
the third row.
For greater cargo capacity, the seats
in the second row can be removed,
and the bench seat in the third row
can be folded into the floor.
Except U.S. LX and Canadian DX
models
Your vehicle has a second row plus-
one seat that can be installed
between the second row bucket
seats when needed. The plus-one
seat can also be used as a second
row center console.
