After the seat reaches a comfortable
temperature, select LO by pushing
the back of the switch. This will keep
the seat warm.In HI, the heater turns of f when the
seat gets warm, and turns back on

In LO, the heater does not cycle with

Because of the sensors f or the side
airbag system, there is no heater in
the passenger’s seat-back.
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 f rom the
battery.
If the engine is lef t idling f or an
extended period, do not use the
seat heaters, even on the LO
setting. It can weaken the battery,
causing hard starting.
