How to Break in an Automatic Transmission New Car on the Highway
1 Answers
Keep the car under a certain load, meaning you can carry a few passengers or some cargo. Most automatic transmission cars are also manual-automatic, so if you're an experienced driver, it's best to start in manual mode. When breaking in the car on the highway, initially use manual mode to shift up one gear at a time. After switching to D mode, drive for another 20 kilometers—that's when the car is truly broken in. Once properly broken in, the fuel injectors will atomize fuel efficiently, making the car more fuel-efficient in the future.
