‘95 S420 “Air Injection Inoperable”

Got a check engine light, and the code is 4 "blinks" for "air injection inoperable." I've seen where some guys try to bypass their pump and just roll with it not working. My question: is it safe to just let it not work? Car's been driving beautifully, and in a warm-weather climate, I'm not really sure I need that pump?
