I noticed to day that the BIG RED TRIANGLE was coming on for a second or so when I would take a sharp turn. What could be the cause of that? I don’t have the car manuel anymore…Kids lost it or threw it out I guess. ---

I Guess That Is The “Replace Owner’s Manual Immediately” Warning Light. CSA ---

Virgil, I Believe That If You Go To “Toyota Owners Online” And Register, You Can Access A Manual. Click this link to go right to the registration and Interactive Owner’s Manual. [http://www.toyotaownersonline.com/](http://www.toyotaownersonline.com/) Please let us know if it works for you. Thanks, CSA ---

I found this reply on the web. You might to get the codes read. The triangle warning light is a master warning light. There is a malfunction in the hybrid and engine control units. The most common problem is because the engine did not start when commanded to. This willl set a P3191 and a P3101 codes. Try turning the key off and restarting. If the engine fails to start the hybrid battery will run down to the point you won’t get it started. ---

Welcome back, CSA. I wondered where you got to. It’s been lonely supporting GM by myself. 😉 ---
