System Description
SYSTEM DIAGRAM
- The steering heater system operates to keep the steering wheel surface temperature between 30°C (86° F) and 40°C (104° F).
- When the steering heater switch is pressed, the A/C auto amp. turns on the steering heater relay, the indicator light in the steering heater switch lights up, and the heat element built into the steering wheel is energized to heat the steering wheel.
- When the steering heater switch is pressed again, the A/C auto amp. turns off the steering heater relay, stops energizing the heat element built into the steering wheel, and turns off the indicator light inside the steering heater switch.
- When the surface temperature of the steering wheel exceeds about 45°C (113° F), the thermostat built into the steering wheel turns off and the heat element is stopped energized. When the surface temperature becomes less than about 30°C (86° F), the thermostat turns on and the heat element is energized.
- The A/C auto amp. has a built-in timer, and after the steering heater switch is turned on, the steering heater relay is turned OFF and heating is stopped when the specified operating time (30 minutes) elapses.
- The operating time during auto does not depend on the specified time (30 minutes).
NOTE:
If the surface temperature of the steering wheel is below 30° C (86° F), the system will heat the steering wheel and cycle off and on to maintain a temperature above 30° C (86° F). 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.
