Shoulder Belt Height Adjuster
The vehicle has a shoulder belt height adjuster for the driver and right front passenger seating 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 on page 3‑13.

Move the height adjuster up to the desired position by pushing up on the height adjuster.
After the height adjuster is set to the desired position, try to move it down without pressing the release button (A) to make sure it has locked into position. Press the release button to lower the height adjuster.
