I suppose you are asking about high mileage preventative maintanance items that is not covered in the manual.

I hear that at 150,000 miles or 7 years all the hoses should be replaced. They may look fine from the outside, but rubber does rot over time from heat, and hoses rots from the inside. Also, I don't think the manual doesn't list a time to flush the radiator, so if you havn't done that, you might do it.

The manual does lists 70,000 miles timing belts, 100,000 mile fuel filter for the S70, so hopefully you have already done those high mileage maintenance items.

It may also be time to do the 2 year brake flush, and 30,000 mile spark plug change.
