Seat Heaters The HI or LO indicator lights and remains lit until you turn it off. To turn the heater off, push the opposite side of the switch lightly. The indicator will turn off. In HI, the heater turns off when the seat gets warm, and turns back on after the seat's temperature drops. It continues to cycle as long as you leave it set on HI. The HI indicator remains lit as a reminder that you have the heater on. On Canadian models Both front seats are equipped with seat heaters. The ignition switch must be ON (II) to use them. Push the front of the switch, HI, to rapidly heat up the seat. After the seat reaches a comfortable temperature, select LO by pushing the back of the switch. This will keep the seat warm. In LO, the heater runs continuously. It does not cycle with temperature changes. Follow these precautions whenever you use the seat heaters: Use the HI setting only to heat the seats quickly. Select the LO setting when the seats feel warm. The HI setting draws large amounts of current from the battery. Do not use the seat heaters, even on the LO setting, if the engine is left idling for an extended period. They can weaken the battery, causing hard starting. SEAT HEATER Instruments and Controls
