The location of the lock button and the direction of movement for adjusting the height of the upper belt anchorage
When adjusting the seat belt attachment, set it to a height high enough to ensure that the belt is firmly in contact with your shoulder and at the same time that the belt DOES NOT touch your neck.
To adjust the seatbelt height, press the seatbelt height lock button and move the seatbelt anchor up or down to the desired position that ensures the seatbelt is firmly in contact with your shoulder. Release the lock button to secure the strap attachment. After you release the lock button, try moving the seat belt anchors down or up to make sure the anchor is securely locked in position.
Warning! The seat belt anchor must be fixed while the vehicle is in motion.
Warning! Improper adjustment of the seat belt height may reduce the effectiveness of the seat belt in the event of an accident.
