Identify mystery button - A190 Avantgarde W168

[removed]

Need help - this little button has been puzzling me for a while now.

I imported my car from Japan a few months ago, but even the Japanese manual doesn't show the button (no, I can't speak Japanese but I went through the book checking all the pictures - the relevant one is exactly the same as in UK manual - i.e. shows nothing to the right of mirrors folding button...)

Has anybody got any idea as what that button might be? Never saw it lit up, BTW.

Wing mirror adjustment...? Just a guess.

Also... might not be an original MB button - it seems odd as it is round and the others are rectangular? Perhaps some sort of after-market retrofit?

after market heated seat switch

Wing mirror adjustment is on the dash under the heater controls.

It looks aftermarket ...

What happens when you press it ?

I think seat heater as well....probably not really required in the Bahamas.

Yep, definitely not mirror adjustment.
Never thought about it being aftermarket ... hmm
Nothing happened, as far as I can remember, need to test it some more I guess.

Heated seats ... just what I need here LOL

Rear fog light?

If it was heated seats , that would have a fair old current draw wouldn't it ?

Could you ( at night ) turn the headlights on , with the ignition on , but without the car actually running and watch to see if the lights momentarily dim when you flick the switch ?

Rear fog light?

No, that's on the main light switch

Oh, and the seat heating buttons are on the panel on top of radio - far right and far left ones for the drivers and front passenger respectively ... maybe this little one is for the rear?

Definately aftermarket, I'd say some sort of aftermarket alarm device, maybe a switch for a dummy alarm led???

on/off LED spot Iluminated rocker switch - RED 12v on eBay (end time 04-Apr-11 16:01:04 BST)

it could also be a garage opener if it is a push only switch...

 

[KillerHERTZ]

Could it be an aftermarket garage door opener switch?

Has the car got a tow bar fitted? Might be something to do with the electrics for it...
