If your vehicle has this feature, the switches are located on the outboard side of the driver's and passenger's seats.

This feature will heat the lower cushion and lower back of the driver's and passenger's seats.

Press LO to turn the heater on low. Press HI to turn the heater on high. Put the switch in the center position to turn the heater off.

The engine must be running for the heated seats to work. Also, the passenger's safety belt must be buckled for the heated seat feature to work on the passenger's seat.

If you turn the ignition off when the heated seats are on, the heated seats will turn off. They will come on again when you restart the vehicle.
