Main Menu Table Of Contents Seat Heaters Passenger's Seat 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 whenever you use the seat heaters: HEATERS Driver's Seat SEAT HEATER SWITCHES On EX-L model Both front seats are equipped with seat heaters. The passenger seat is only heated in the seat bottom because of the side airbag cutoff system. The ignition switch must be in the ON (II) position to use seat heaters. 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. 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. 100 2009 Civic Sedan
