It is not the most obvious place to put switch I must say. The problem I have with it is that I often forget to turn it off! Does anyone know if there is a built in cut off timer for the door mirrors like the heated rear screen?

The heated mirrors only operate when the engine is running and up to an external temperature of +35 degrees.

No mention of thermostat control.

No there isn't.

That's right if you rotate to the on position they are on every time you drive the car!

What trim level do you need to get heated mirrors?
