Pull up on the latch plate to make sure itis secure. When the shoulder belt is pulled out all theway, it will lock. If it does, let it go back all the way and start again. If the belt is not long enough, see Safety Belt Extender on page 1-28. Make sure the release button on the buckle is positioned so you would be able to unbuckle the safety belt quickly if you ever had to. 1. Pick up the latch plate and pull the belt across you. Don't let it get twisted. The shoulder belt may lock if you pull the belt across you very quickly. If this happens, let the belt go back slightly to unlock it. Then pull the belt across you more slowly. 3. To make the lap part tight, pull down on the buckle end of the belt as you pull up on the shoulder part. 1-24
