Folding Rear Seats (If equipped)
The release knobs for the split rear folding seatbacks are in the
trunk. Pull the knob to fold down the seat.
To raise the rear seatback, push the seatback upward until it
locks in place. Make sure it is firmly latched by pushing
forward and back on it.
Check to see that the seat and seatback are latched
securely in position. Keep floor area free of objects that
would prevent proper seat engagement. Never attempt to
adjust the seat while the vehicle is in motion.
