Kia Optima: Heated Steering wheel. Description and Operation

Description

The heated steering wheel features an internal heating element that maintains the steering wheel temperature to a consistent level during cold seasons. A heater element has been integrated into the steering handle to maximize driver comfort during cold seasons. The steering wheel heating system will not be active with an ambient temperature above the system set point temperature. The steering wheel heater element is connected through a wire harness and regulated through an electronic control module.The control module responds to a temperature sensor’s (negative temperature coefficient - NTC thermistor) resistance change, which is in direct contact with the steering wheel heater element.
