The heated steering wheel system is designed to operate only when the surface temperature of the steering wheel is below 68F (20C).
Push the heated steering wheel switch to warm the steering wheel after the engine starts. The indicator light will come on.
If the surface temperature of the steering wheel is below 68F (20C), the system will heat the steering wheel and cycle off and on to maintain a temperature above 68F (20C). 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.
NOTE:
If the surface temperature of the steering wheel is above 68F (20C) when the switch is turned on, the system will not heat the steering wheel. This is not a malfunction.
