There is a mysterious small black button close to each rear ashtray in
the back seat of my 1979 450slc. I thought that these were after
market but have since seen the same buttons on other pics from the
same model. What the heck is this used for? Obviously I have not yet
invested in the OEM user\service manual.
Additionally, I have a missing "button" on the upper right of my
console and was wondering what used to be there. Looking at other
pics and noticing that it is a rotary dial I thought that it may
possibly be a volume control for the radio. The console has all the
other buttons intact and functional (emergency flasher, four window
controls, windows lockout button) but the gaping hole eludes me.
Sorry about my ignorance but I am becoming 'Mercedizes' as quickly as
possible...I can't get enough!!
