When the shift position is in P, if the vehicle is left in ACCESSORY or ON mode

mode) or one hour (ON mode), the “POWER” switch will automatically turn off.

However, this function cannot entirely prevent the 12-volt battery from discharging.

Do not leave the vehicle with the “POWER” switch in ACCESSORY or ON mode
