Your vehicle has LATCH lower anchors for child seat installation at the
seating positions marked with the child seat symbol.
The LATCH anchors are located at the rear section of the rear seat
between the cushion and seatback, below the locator symbols on the seat
back. Follow the child seat manufacturer's instructions to properly install
a child seat with LATCH attachments.
The locator symbols are on round plastic buttons for the center seat and
on rectangular tags for the outboard seats.
