HEATED STEERING WHEEL SYSTEM : Heated Steering Wheel
INFOID:0000000010119076
With the power supply from the heated steering wheel relay, the
heated steering wheel controls temperature through the heating ele-
ment (1) and thermostat (2) built into the steering wheel.
• Heating element: Generates heat by energization.
NOTE:
Heating element is located at the back of the steering wheel
leather surface.
• Thermostat: Turns ON/OFF power supply according to the speci-
fied temperature.

INFOID:0000000010119077
• The heated steering wheel switch include the indicator lamp. It
turns ON when the system starts.
• The heated steering wheel switch transmits a heated steering
wheel ON/OFF signal to the A/C auto amp.
HEATED STEERING WHEEL SYSTEM : Heated Steering Wheel Relay
INFOID:0000000010119078
Through the control of the A/C auto amp., the heated steering wheel relay turns ON/OFF electricity to the
heating element built-in the steering wheel and turns ON/OFF the indicator lamp mounted on the heated steer-
ing wheel switch. For location, refer to
ST-8, "HEATED STEERING WHEEL SYSTEM : Component Parts
.
HEATED STEERING WHEEL SYSTEM : A/C Auto Amp.
INFOID:0000000010119079
• A/C auto amp. turns ON/OFF the heated steering wheel relay, according to a signal transmitted from the
heated steering wheel switch.
• The A/C auto amp. includes a timer. The heated steering wheel relay is turned OFF when the timer operat-
ing time reaches 30 minutes.
- Timer: Turns ON/OFF the heated steering wheel relay for a specified period of time

SYSTEM DIAGRAM
DESCRIPTION
• The heated steering wheel system maintains the surface temperature of the steering wheel between 20
°C
(68
°F) and 30°C (86°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 steer-
ing 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
°C (86°F), the thermostat built-in the
steering wheel turns OFF, and electricity to the heating element is turned OFF. When the surface tempera-
ture drops to less than 20
°C (68°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
HAC-38, "AUTOMATIC AIR CONDITIONING SYSTEM : A/C-Heater Timer (Climate Ctrl. Timer)"
(with
heat pump) or
HAC-236, "AUTOMATIC AIR CONDITIONING SYSTEM : A/C-Heater Timer (Climate Ctrl.
(without heat pump).
