Taken from ATUHM user manual:

[Operator Override—Safety Protocol]
Should the operator become incapacitated during Manual Operation Mode, the Sonet Intelligence Drive (SID) will assume automatic control and immediately deactivate all ATUHM functions until further commands are issued. The operator’s safety and well-being are always the SID’s foremost concern.
