It is optimal to perform the third maintenance of a car at around 15,000 to 20,000 kilometers. More information about car maintenance is as follows: 1. Car maintenance refers to the preventive work of regularly inspecting, cleaning, supplying, lubricating, adjusting, or replacing certain parts of the car, also known as car servicing. 2. Car maintenance mainly includes the maintenance scope of the engine system, transmission system, air conditioning system, cooling system, fuel system, power steering system, etc. 3. The purpose of car maintenance is to keep the car clean, eliminate hidden dangers, prevent failures, slow down the deterioration process, and extend the service life.

I just got my third new car, and the optimal mileage for the third maintenance is usually between 15,000 to 20,000 kilometers, depending on the model. For example, my family’s Toyota has a manual that recommends maintenance every 5,000 kilometers, so three times would safely add up to 15,000 kilometers. Why? By then, the engine is well broken-in, and the oil gets dirty, which can easily affect performance. Changing the oil, replacing the filter, and checking the brakes are routine tasks. Doing it too early is a waste of money, while delaying it beyond 20,000 kilometers increases the risk of engine carbon buildup, which can be very expensive to fix. It’s best to check the manual or consult the 4S dealership—they can tailor a plan for you. Remember, a car is like a person; timely maintenance extends its lifespan and saves you a fortune on repairs.

What is the reason for the exhaust system warning light in the Magotan?

Reasons for the exhaust system warning light in the Magotan: 1. If the exhaust system warning light comes on and then goes off, it may be due to poor fuel quality, which is a normal phenomenon; 2. If the exhaust system warning light stays on continuously, it may indicate a problem with the car's engine or the three-way catalytic converter. In this case, it is necessary to go to a repair shop or a 4S store for professional inspection and repair. The dimensions of the Magotan are 4866mm in length, 1832mm in width, and 1464mm in height, with a wheelbase of 2812mm.

What is the principle of an automotive electronic regulator?

The principle of an automotive electronic regulator is: When the engine's output voltage is too low or fails due to other reasons, the battery will generate a current in the generator's windings (known as reverse current). The electronic regulator cuts off this reverse current to prevent over-discharge of the battery, which could damage the battery, and to avoid excessive current flowing into the generator windings, which could damage the generator. The regulator consists of three relays: one is responsible for adjusting the generator's output voltage, another for preventing excessive charging current. When the charging current is too high, the circuit activates both the voltage regulation relay and the current limiting relay simultaneously, disconnecting the generator's excitation circuit and stopping the generator. The third relay is responsible for cutting off the charging circuit when reverse current occurs, activating to disconnect the charging circuit in such cases.

Should You Power On First or Plug In First When Charging a New Energy Vehicle?

When charging, power on first, then plug in the charging gun. When disconnecting, unplug the charging gun first, then power off. Here is some relevant information about new energy vehicles: 1. Recommendations: The number of charge/discharge cycles has no direct impact on the lifespan of the power battery. The battery itself has no memory function. In principle, it is recommended that customers charge and discharge promptly, as timely charging and discharging can maintain the battery's good charge/discharge capability. 2. Winter Usage Tips: Charging immediately after use in winter ensures the power battery remains at a relatively high temperature, avoiding the heating phase during charging and effectively reducing charging time. If the current range does not affect normal travel, it is also acceptable to perform a charge/discharge cycle every 3-5 days on average.
