I need some clarification.  In section 20.19 of my Bentley it reads - switch on for 30 seconds.  Does that mean to just turn the key to the on position and not actually turn the engine over?

Also, what does it mean by the minimum rate being 500 cm?  What does the cm stand for?  How much should it fill a quart jar at minimum?

Thanks,
