There are 2 different engines that came in the Lucerne in 2006 and I am not sure which one the CXS had. In any case below are pictures of both engines as well as locations. If you have the 3.8 liter (6 cylinder) engine you can add coolant directly to the radiator in the spot marked "A". But on your regular fluid checks you want to make sure that where the "B" is marked that the overflow tank there has fluid up to the line that says "full". If you have the 4.6 liter (8 cylinder) engine the overflow tank and where you fill up the radiator are the same (location "A") so that is the location you would fill the radiator as well as check to make sure there is coolant to the "full" line on the tank on your regular fluid checks, When you look at the pictures below you will understand easier. I hope this helps and good luck.

Could be leaky spark plug wires sending some of the spark into the atmosphere. At night if you peep under the hood you would probably see these tiny sparks popping out of the worn wires. Also you may need a tuneup.
