Actually, Toyota dealers must turn off the SAS system if so requested by the customer. The customer needs to sign a waiver and the dealer can come in and actually shut down the system. This has been done by some of my customers that I service. OSHA has nothing to say about shutting down the SAS system since the system is not mentioned anywhere in their wording of any laws or requirements governing forklifts. I would recommend to any customer who is unhappy with the SAS system simply contacting Toyota directly (circumventing the dealer) and requesting the SAS be shut down.
