488 Engine control system failure message

That's one reason I have a generic OBD-II code reader. Sometimes it can tell you what the problem is so you can decide if it's safe to drive to the dealer or if you're better off getting a flatbed. For that matter a brand-specific one will come preloaded with the codes unique to your car and have extra menus and test procedures and is still cheaper than a full dealer diagnostic machine, but a $20 Amazon one is nice to have around.
Having said all that, I'd try shutting it completely off for 10 minutes and try again. If it's an intermittent failure (which is pretty common with a failing sensor, the most common issue you'll see), it will frequently go away after a couple cycles. I definitely wouldn't start a road trip like this, but it might get you home. Avoid high speed and full throttle until you can properly diagnose it.
