heated mirrors not great MY23

[george72]

Is it me or are the heated mirrors just not very good at all?  should i be pressing some button to activate them, they don't appear to be defrosting very well at all.

Mine are slow on my MY22 but the worst is the rear screen de-mister it takes forever.

To operate the rear window defogger and the heated exterior rear view mirrors one must press the defogger switch (H) on the climate control panel

thanks @Peter , i did not know that the rear windows and rear view mirrors operated on the same switch. This function was always automatic on my previous 5 series.

Yes, my Mercs' mirrors were heated automatically at temps below ~9c, no way to switch them on or off manually and they never had a hint of mist/water on them either!

It may be easier & quicker to spray little deicer then wipe with a cloth.

I was initially surprised by the OPs since I have always been quite impressed by Lexus’ rear window/side-mirrors heating/defogging function insofar as it seems perfectly synchronised, I.e. there is no need to wait for a second area to clear after the first before switching it off again.  The clearing effect generally also seems sufficiently rapid to reduce Battery strain on cold winter mornings.
