The vehicle has a shoulder belt height adjuster for the driver and right front passenger positions.

Adjust the height so the shoulder portion of the belt is on the shoulder and not falling off of it. The belt should be close to, but not contacting, the neck. Improper shoulder belt height adjustment could reduce the effectiveness of the safety belt in a crash. See How to Wear Safety Belts Properly  .

Squeeze the buttons (A) on the sides of the height adjuster and move the height adjuster to the desired position.

The adjuster can be moved up just by pushing up on the shoulder belt guide.

After the adjuster is set to the desired position, try to move it down without squeezing the buttons to make sure it has locked into position.
