Does an Automatic Transmission New Car Need a Break-in Period?

[OPeyton]

If the vehicle's user manual does not specify otherwise, an automatic transmission new car does require a break-in period. Introduction to break-in mileage: The break-in mileage for a new car is generally 1,000-3,000 kilometers. The initial break-in period is 0-500 kilometers, during which you must avoid aggressively revving the engine or braking sharply. Driving speed and engine RPM should not be too high—speed should not exceed 70 km/h, and engine RPM is best kept below 2,000 rpm. The mid-term break-in period is 500-1,000 kilometers, during which driving speed and engine RPM can be appropriately increased, but should not exceed 90 km/h, with the engine's maximum RPM reaching up to 2,500 rpm. The late break-in period is 1,000-3,000 kilometers, during which speed can reach up to 120 km/h when road conditions are good. Introduction to warming up the car: Do not start driving immediately after starting the car; wait until the coolant reaches normal operating temperature before moving. Especially in cold winter, gently press the accelerator pedal to allow the engine to operate at a slow pace. If the car is driven without warming up, it should be driven at low speed for the first 5 minutes after starting, until the coolant temperature in the radiator is sufficient before accelerating.
