Inclining front seats for rear seat entry
16sa29b
Lift the seatback lock release lever on the side of the seat
or on the side of the seatback. The seatback will incline.
This allows passengers to get in or out of the rear seat easily.
If a driver or front passenger uses a seat belt guide, be sure to
remove it before inclining the seatback. For seat belt guides,
see page 106. After a passenger gets in or out, return the
seatback until it locks.
