Typically not a lot is needed. Since you are asking this about a 05 RL with 100K mile I wanted to ask whether you are the first owner or did you recently aquire the RL...

Also degree of winterizing will depend on where you live.

Don't forget the timing belt...should be MID item. Generally, I think about 105K miles??
