COMFORT ADJUSTMENT D Inspect the belt system periodically. Check for cuts, fraying, and loose parts. Damaged parts should be replaced. Do not disassemble or modify the system. D Keep the belts clean and dry. If they need cleaning, use a mild soap solution or lukewarm water. Never use bleach, dye, or abrasive cleaners - they may severely weaken the belts. (See "Cleaning the interior" on page 409 for instructions.) D Replace the belt assembly (including bolts) if it has been used in a severe impact. The entire assembly should be replaced even if damage is not obvious. Front seat belts Make sure the seat belt hanger is secured in raised position.
