I noticed this on the Maintenance schedule:

Inspect and lubricate all non-sealed steering linkage,ball joints,suspension joints,half and drive-shafts and u-joints.

Is there a diagram that points out these lubrication points?

 

I 'think' everything is sealed and lubed for 'life'. I've looked on my past cars (15 or so years) and haven't found any grease fittings

 

I would call up the dealer service dept and ask for further info. They may not give a diagram, but they'll probably orate a list of places to lube. I've found them to be helpful with questions like this.
