The seatbacks of the rear seats can be folded down.
Before folding down the seatbacks
Apply the parking brake firmly and shift the shift lever to P.
Depending on the position of the front seat, if the seatback is folded backward, it may interfere with the operation of the rear seat.
Folding down the seatbacks
Pull the seatback lock release lever and fold the seatback down.

Returning the rear seatbacks
To avoid trapping the seat belt between the seat and the inside of the vehicle, pass the seat belt inside the seat belt guide and then return the seatback securely to the locked position.

■When folding the rear seatbacks down
■After returning the rear seatback to the upright position
If the seatback is not securely locked, the red marking will be visible on the seatback lock release knob. Make sure that the red marking is not visible.

If the seat belt gets caught between the seatback's securing hook and latch, it may damage the seat belt.
