When Can a New Car Be Driven on the Highway?

[LaBrandon]

A new car can be driven on the highway after traveling 5,000 kilometers. During the break-in period, the new car should avoid high-speed driving at speeds above 90 kilometers per hour. When the new car has traveled approximately 5,000 kilometers and is about to complete the break-in period, the owner can briefly run the engine at over 4,000 RPM to reduce carbon buildup and enhance engine performance. New car break-in considerations: 1. During the break-in period, avoid driving with a full load, as excessive weight increases the load on the engine and transmission, leading to higher engine output power and excessive wear on components; 2. Owners should avoid prolonged use of low gears, allowing each gear to undergo break-in. Automatic transmission cars eliminate the need for manual gear shift break-in; 3. Under good road conditions, the owner should accelerate continuously to allow the transmission to shift up smoothly, preventing insufficient break-in of high gears.
