Vehicle was unintentionally left idling for three hours with the A/C at Max on a 90°F day. Temperature gauge was at 80%, engine light was blinking, traction light and VSC OFF was on, idle RPMs wasnt erratic but the needle not solidly in place like usual. It was driven away anyway from one location to another about 5 miles away with poor acceleration and transmission shifting.
Then it was turned off for 30 minutes and now everything is perfectly fine. So my questions are,
1.) What safeguards, if any, does the Highlander have to mitigate overheating? I have to assume they exist, but I'd like to know specifically what they are and the manual has no information, and Google has not been helpful.
2.) What all should I check to try and find if any damage did take place that may speed up wear to a component or otherwise cause problems later?
