 Third seat
Lean forward and pull the lock release lever. Then lean

CAUTION
To reduce the risk of sliding under the lap belt during a
collision, avoid reclining the seatback any more than
needed. The seat belts provide maximum protection
when the passengers are sitting up straight and well
back in the seats. If you are reclined, the lap belt may
slide past your hips and apply restraint forces directly
to the abdomen. In the event of a frontal collision, the
more the seat is reclined, the greater the risk of personal
injury.
