Bought an 86 420 SEL with no owners manual. Warning light between the emergency brake light and the oil level light came on this morning (it's a circle with three dots on each side). Which warning is this?

In a few hundred miles or less, your rotors will be touching your disc brake backing plates - it is the brake pad wear warning.
Replace the sensors when you replace the pads, now that they've been touching the rotors.
