I confirmed it today. Went for a good long drive, and brought my infra-red thermometer. It wasn't too cold today - hovering around 0C (32F).

I started the car, and hit the steering heater button, heated seats on full, and rear defrost, and then de-snowed her. I was ready to leave in about 10 minutes.

When I got in the car, the air coming from the vents was still cold, but the seats and steering wheel were nice and toasty. I took a temp measurement where the steering wheel meets the center portion on the left side. It measured in the mid/high-90s F. It wasn't as hot as I've felt it when it's -20 outside, but it was hot. I took measurements as I was driving, and over time, as the cabin temperature increased, the temperature at that spot dropped to the low 80s F. t never went below 80F with the heating button lit, and it never shut itself off.

At one point, while driving, I switched the steering wheel heat off, and waited for the steering wheel to cool down, and I got a measurement in the low 70s F, so it wasn't cycling on/off, the temperature was adjusting to the interior temperature. What an awesome design! I love this even more, now!
