my check hybrid system warning light came on then the check VSC System came on briefly and the car then stopped. Check Hybrid System light came back on but I was able to start the car again. It seems ok except for the Check hybrid system light remains on. The manual says stop your vehicle and call a Toyota dealer, however, I had to drive a few more miles to get home since it was late at night and 19 degrees outside.

Get the car to a Toyota specialist. Probably best to tow it to prevent further problems.

HI! I have had this happen several times to my 2006 Highlander Hybrid. It always occured a few days after the little 12 volt battery had run down (due to dome light left on, door ajar). The first time was on a trip to Denver Colorado. My car did the same things as you described that yours did. I didn't have my scan tool with me to read the codes so after inspecting everthing under the hood I disconnected the 12 volt battery for about 2 minutes and reconnected it. This cleared the code and the problem never reappeared. About a month ago an interior light was left on for a few days and the battery was run down again. I jupmed it to get it started and about 3 days later I got the VSC lights again. I disconnected the battery to clear the error and it never reappeared again.

Thanks , I did take it to the dealer and all it was just a loose connection with 12v battery cable.

this message might appear when the gasoline in the tank is very low
fill the tank and it will vanish

I had the exact same symptoms on my '06 HiHy. 12 V battery had run empty with key in ignition overnight and even after trickle charging it back to health and running the engine for > 1 hour around town, the 'Check Engine' and 'Check Hybrid System' messages wouldn't go away. Following the advice here, by disconnecting the negative lead on the 12 v battery for ~ 2 minutes, the messages all went away (as did my radio presets, but who's complaining!).
