Cleaning the seat belts
► Use clean, lukewarm water and soap solution.
Do not clean the seat belts using chemical
cleaning agents. Do not dry the seat belts
by warming them above 176 °F (80 °C) or
placing them in direct sunlight.
WARNING 
Do not bleach or dye seat belts as this may
severely weaken them. In a crash, they may
not be able to provide adequate protection.
