To reinstall the rear seat cushion, do the following: {CAUTION: A safety belt that isn't properly routed through the seat cushion or is twisted won't provide the protection needed in a crash. If the safetybelt hasn't been routed through the seat cushion at all, it won't be there to work for the next passenger. The person sitting in that position could be badly injured. After reinstalling the seat cushion, always check to be sure that the safety belts are properly routed and are not twisted. 5-103
