Auto power off function

If the vehicle is left in ACCESSORY mode for more than 20 minutes or ON
mode (the fuel cell system is not operating) for more than an hour with the
shift position in P, the power switch will automatically turn off. However, this
function cannot entirely prevent 12-volt battery discharge. Do not leave the
vehicle with the power switch in ACCESSORY or ON mode for long periods
of time when the fuel cell system is not operating.
