Glad you asked Josh. Here’s an exact situation that just happened recently:
A vehicle threw the serpentine belt. Cluster lights up like a Christmas tree and temp starts climbing rapidly. I’m 7 miles from home. Initiate emergency procedures. Going 50mph. Shift to neutral. Shut engine off and go to ACC mode. Passive air cools the engine and gravity continues to propel vehicle. Just prior to getting to the bottom of each hill, restart engine whole vehicle is still moving. Climb hill. Shift to neutral, stop engine. Got home without overheating or needing a tow. But also - let’s assume the throttle stuck or other unanticipated acceleration event. > On Dec 16, 2018, at 13:55, Josh Luthman <[email protected]> wrote: > > Why would you emergency shut off the engine?
