How do you use the automatic gear in City Car Driving?

Recently I’ve noticed that when I’m driving—and especially if I’m accelerating or on the highway—my car makes a lot of noise, like a motorbike or something. Why does my car suddenly sound like a motorcycle?

I’m thinking about getting a Jeep for my next car, but I’ve heard they can be expensive. I’m handy with cars and can fix most things on my own, but if the parts are too expensive I don’t know if it will be worth it. Are Jeep parts expensive?

I want to talk about certain features in my car that I think could be dangerous. What’s the easiest way to get in touch with Toyota customer service?
