How to Best Use Stabilization in Canon Lens

I have purchased a "used" Canon telephone lens - 100-400mm zoom - and I love it. It has two settings for stabilization on the lens. I most often use it on a "monopod" when taking surfing shots. What is the "Canon" recommended or best way to use or not use the stabilization in either I mode, or II mode, or not at all? Thanks for your response ahead of time.

  Mode I is for handheld use, where your movements may be in any direction. Mode II is for panning shots, where you are tracking a subject horizontally and the IS will correct only for up/down camera movement. On a monopod, you can use either, or simply turn IS off since you may be sufficiently stabilized. Fully supported on a solid tripod, Canon's recommendation is to turn IS off on early generation IS lenses: EF 75-300 f/4-5.6 IS USM (discontinued), EF 300 f/4L IS USM, EF 28-135 f/3.5-5.6 IS USM, and EF 100-400 f/4.5-5.6L IS USM). This is because the IS can be fooled by the lack of motion and start acting erratically trying to correct motion that isn't there.
