Hello everybody! I had driving my own 1991 Previa LE (auto) since 1 month ago. My previous car was a Toyota Tercel. Now, my Previa has Cruise Control and Overdrive but, I don't know about the correct use of them. When I have to use them?. And its benefits. I live in Costa Rica and is so hard to find the Owner's Manual for my Previa here. Could somebody help me to learn the use of these controls in my car. Thanks all. Mario Chaves
