How many kilometers should a new car run before going on the highway?

[FranciscoMarie]

New cars can go directly on the highway. Precautions for new cars running on the highway: 1. Warm up in advance: Whether driving on the highway or daily driving, when the car is cold, you should drive slowly for a period of time (speed not exceeding 60km/h), and wait until the water temperature of the vehicle reaches the normal operating temperature before driving quickly. 2. Avoid aggressive driving: It is recommended that the RPM not exceed 3000 when accelerating a new car. Slow acceleration makes it easy for a new car to reach 120km/h on the highway. 3. Avoid driving on the highway for long periods: It is recommended to take a break in the service area every 4 hours, giving the new car some rest time and allowing the driver to relax. After all, driving for long periods is very dangerous. 4. Use reliable fuel: Different car engines have different compression ratios, so the fuel grades used are also different. You must strictly follow the manufacturer's regulations when refueling.
