after the vehicle is shut off or disabled. To prevent serious injury
or death from severe burns or electric shock, avoid touching,
cutting, or breaching any orange high voltage power cable or high
voltage component.

The SRS may remain powered for up to 90 seconds after the vehicle
is shut off or disabled. To prevent serious injury or death from
unintentional SRS deployment, avoid breaching the SRS
