Be careful not to damage the belt webbing or
hardware. Take care that they do not get caught or
pinched in the seat or doors.
 Inspect the belt system periodically. Check for cuts,
fraying, and loose parts. Damaged parts should be
replaced. Do not disassemble or modify the system.
 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, or allow them
to come into contact with the belt they may severely
weaken the belts. (See “Cleaning the interior” on
page 515 for instructions.)
 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 belt buckle illumination
