The front seat controls are located in the center console. The rear seat controls are located on the rear doors.

Push the button once for a high setting, twice for a low setting, and a third time to turn off the heated seat. The LO setting warms the seatback and cushion until the seat approximates body temperature. The HI setting heats the seat to a slightly higher temperature.

The heated seats can only be used when the ignition is turned on. The heating elements in the seats automatically turn off when the vehicle's ignition is turned off.

Only the outboard rear seat positions have heating elements.
