HEATED STEERING WHEEL
System Diagram
System Description
The heated steering wheel switch controls the heated steering relay. When the switch is turned on, the relay is energized and the heated steering system will operate. The heated steering system will turn off when the steering wheel temperature reaches approximately 86 F (30 C). Heated steering system operation can also be canceled by pressing the heated steering wheel switch again.
NOTE: If the surface temperature of the steering wheel is below 68 F (20 C), the system will heat the steering wheel and cycle off and on to maintain a temperature above 68 F (20 C). The indicator light will remain on as long as the system is on. Push the switch again to turn the heated steering wheel system off manually. The indicator light will go off.
