This morning my local weather was a brisk 14F here north of Dallas, and we were a relativly warm spot in the US.
My Cadillac lost its garage spot to an antique Roadster replica I am restoring, so we both start out in the cold together. Before I used it, I considered the heated steering wheel a bell or whistle sort of accessory — interesting, but not all that useful. Now it is one of my favorite comfort accessories in the winter. The heated steering wheel is an electric coil arrangement under the leather of the wheel, and is controlled by a switch on the steering wheel. On a cold morning it is very cozy.
Heated seats are easier to understand the value, and my 2nd thing to turn on. The heated seats in my STS-V have 3 selections for intensity; I prefer the lowest setting. I toggle the seat heater on, then turn it down twice to low. By the time I am well on my way, my core temp is warm.
Cooled seats have been harder for me to get used to in review vehicles that had them. Cold air from the seat gives a jarring impression rather than comfort. Perhaps it is an acquired taste.
Do you use your heated or cooled seats a lot or are they frills?
