If you leave the door mirror control button on the demist position (i.e. with the pointer vertical) is it harmful or does it stop heating after a short time anyway?

If you mean the heated mirrors, I know my mums previous Meriva (before she saw sense and got a Fabia :p) had auto heated mirrors, after about say 5 6 years one of the mirrors plopped out when it got knocked because the heat had in essence melted the glue holding it in, might be different for Skoda, I'm pretty sure mine are clipped in

The Mk. 2 mirrors certainly had a habit of falling off but I don't know if that was due to them heating up. I re-fixed mine with epoxy and they gave no more trouble.

It was so common that I would have hoped they will have fixed that for the Mk. 3

From earlier thread, mirrors heat level changes:

The mirrors work differently to previous models in that the MK1 heated mirrors were supplied with a direct and constant 12v linked to the rear window heater so it times out. The MK2 does not have a link/timeout from the rear window heater. The reason being that turning off the heating while on a motorway when it is raining or snowing was deemed to present safety concerns and from a point of view of safety for road traffic and particularly while on the motorway, the heater must not timeout by itself. With your current car the MK3, mirrors are supplied via a 12v PWM (Pulse Width Modulated) signal. This means that the mirrors can be pulsed with for example 50% PWM signal and would therefore only heat the mirror to 50% capacity. This value can drop as low as 5%. The duration of the PWN signal is calculated using information from road speed (via CAN) and ambient temperature. The higher the road speed the higher the PWM to take account for wind chill at high road speeds and the ambient temperature is an input for obvious reasons. I have included an example below. Also the system will not operate without the engine running and will switch off at temperatures in excess of +35 °C and there is also the option of switching them off using the joystick during mild weather

This precise control provides for a more positive impact for environmental factors and fuel consumption compared to the previous methods of mirror heating.

Example:

T=-15°C & v=90 km/h -> heating intensity 100%

I was interested in this also, as they don't exactly remind you to turn it off / self cancel - sounds ok to leave on then

I left my mirror heater on to clear early morning moisture(Superb Style 2015). I got a reminder on the MFD some time later. Very useful feature.

Its quite a clever system....id suggest in the colder months just leaving it on all the time and let the car do its thing.

Only slight annoyance is that on my car (I have a Golf with standard auto dipping passenger mirror) that if you have the mirror heating on the mirror doesnt dip as its reliant on the mirroe switch being in the L position to do so. Minor gripe but involves contined twidling of the switch.

I don't find the interior mirror mists up at all.

Same on my Leon - bit of an annoyance TBH, especially now I actually use the passenger auto-dip on reverse (due to having to park in a slightly different place).
