yellowblue Shoulder Belt Tightness Adjustment Your car has a shoulder belt tightness adjustment feature. If the shoulder belt seems too tight, adjust it before you begin to drive. 1. Sit well back in the seat. 2. Start pulling the shoulder belt out. 4. Let the belt go back all the way. You should hear a slight clicking sound. If you don't, the adjustment feature won't set, and you'll have to start again. 5. Now you can add a small amount of slack. Lean forward slightly, then sit back. If you've added more than 1 inch (25 mm) of slack, pull the shoulder belt out as you did before and start again. 3. Just before it reaches the end, give it a quick pull. 1-15
