Head Restraint Adjustment
Do not drive until the head restraints for all occupants are installed and adjusted properly.
To achieve a comfortable seating position, change the seatback recline angle as little as necessary while keeping the seat and the head restraint height in the proper position.
For more information see Head Restraints on page 3‑2 and Seat Adjustment on page 3‑3.
