Seat Heaters In the HI setting, the heater turns off when the seat gets warm, and turns back on after the seat's temperature drops. In the LO setting, the heater runs continuously. It does not cycle with temperature changes. Follow these precautions when using the seat heaters: Use the HI setting only to heat the seats quickly, because it draws large amounts of current from the battery. If the engine is left idling for an extended period, do not use the seat heaters, even on the LO setting. It can weaken the battery, causing hard starting. Push the top of the switch, HI, to rapidly heat up the seat. After the seat reaches a comfortable temperature, select LO by pushing the bottom of the switch. This will keep the seat warm.
