What does Nissan's first and second maintenance mean?

[HavenDella]

Nissan's first and second maintenance refer to the car's first and second maintenance services. Below are the relevant details: Car's first maintenance: The first maintenance for a car, generally recommended at 5,000 kilometers or 6 months. Many brand 4S shops, in order to shorten the maintenance cycle for customers, have adjusted the reminder to suggest maintenance at 3,000 kilometers or 3 months, whichever comes first. First maintenance time: The first maintenance time for a new car is usually determined by either the mileage or the specified first maintenance time, whichever comes first. Therefore, if the time has come but the mileage hasn't been reached, the first maintenance should still be performed. Otherwise, the 4S shop may claim that the standard hasn't been met, resulting in the information not being entered into the nationwide warranty system, leading to a loss of warranty coverage.
