Heated Steering Wheel

Heated Steering Wheel (Option)

The sports and multi-function steering wheel can be equipped with steering wheel heating as an optional extra. The optional multi-function steering wheels in wood and carbon are always equipped with steering wheel heating. The heating for the steering wheel rim can be switched on and off separately using a button on the 6 o'clock spoke (subject to release from energy management system).

Activation and deactivation of the system is indicated on the on-board computer of the instrument cluster.
- "Steering wheel heating ON" or
- "Steering wheel heating OFF"

When the heated steering wheel is activated, the temperature of the steering wheel rim is controlled by a temperature sensor located on the steering wheel rim. When the heated steering wheel is activated, the temperature of the steering wheel rim is kept constant at 95 °F. (35 °C.) by the combined steering column module (CSCM) through a temperature sensor.













Function:
Once activated by the button on the 6 o'clock spoke, the "Heated steering wheel active" request is received by the combined steering column module (CSCM) (conventional signal). The NTC signal from the temperature sensor in the steering wheel rim is now sent to the CSCM and is evaluated by it. The CSCM energizes the heating foil/heating fabric on the steering wheel rim in accordance with this value.
