Just joined the forum and am scanning through but thought I'd pitch in here. I just bought an ML270 and was surprised to find that both door mirrors do not get cleared when you turn on the heated rear screen. On looking in the book it says that the mirror heating comes on '..automatically at low temperatures...'. It does not say how low it has to be and it also doesn't indicate if this is linked into the heated rear screen at all - the description of the heated rear screen does not mention the mirrors. So far we've only got down to 8.5c in my neck of the woods so I assume that is not a 'low temperature' but it is a pain because a heated mirror will clear condensation and rain which will occur at much higher temperatures.
I also found that the auto-locking mechanism can be disabled by holding down the switch on the centre console for a few seconds (in the unlock direction). Check the book, but I think to re-enable it you hold it down in the lock position for a few seconds. Might be worth a check if you still have the problem.
Finally, my book says that only the rear view and driver's side mirrors are dimmed. Not that I can tell the difference between dimmed and undimmed...My car is April 2003, in case that makes a difference.
Hi everyone,
