System Description: Description

The heated steering wheel system maintains the surface temperature of the steering wheel between 20 deg. C (68 deg. F) and 30 deg. C (86 deg. F).
When the heated steering wheel switch is pressed, the A/C auto amp. turns ON the heated steering wheel relay and the indicator lamp mounted on the heated steering wheel switch turns ON. In addition, the heated steering wheel relay turns ON electricity to the heating element built-in the steering wheel to heat the steering wheel.
When the heated steering wheel switch is pressed again, the A/C auto amp. turns OFF the heated steering wheel relay and the indicator lamp mounted on the heated steering wheel switch turns OFF. In addition, the heated steering wheel relay turns OFF electricity to the heating element built-in the steering wheel to heat the steering wheel.
When the surface temperature of the steering wheel is higher than 30 deg. C (86 deg. F), the thermostat built-in the steering wheel turns OFF, and electricity to the heating element is turned OFF. When the surface temperature drops to less than 20 deg. C (68 deg. F), the thermostat built-in the steering wheel turns ON, and electricity to the heating element is turned ON.
The A/C auto amp. has a timer. After the heated steering wheel switch is turned ON, when operating time becomes more than the specified time (30 minutes), the A/C auto amp. turns OFF the heated steering wheel relay to stop heating.
The A/C auto amp. can control the heated steering wheel by the AC-heater timer. For AC-heater timer: refer to System Description (with heat pump system) or System Description (without heat pump system).

NOTE: The indicator lamp will remain on as long as the system is on. Push the heated steering wheel switch again to turn the heated steering wheel system off manually. The indicator lamp will go off.
