3-20 Seats and Restraints Shoulder Belt Height Adjuster The vehicle has shoulder belt height adjusters 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 on page 3‑14. 4. If equipped with a shoulder belt height adjuster, move it to the height that is right for you. See "Shoulder Belt Height Adjuster" in this section for instructions on use and important safety information. To unlatch the belt, push the button on the buckle. The belt should return to its stowed position. Before a door is closed, be sure the belt is out of the way. If a door is slammed against a safety belt, damage can occur to both the safety belt and the vehicle. 5. To make the lap part tight, pull up on the shoulder belt. It may be necessary to pull stitching on the safety belt through the latch plate to fully tighten the lap belt on smaller occupants.
