There are two main aspects to the maintenance of the vehicle. One is the mandatory maintenance provided by the repair station for you. On the other hand, some daily maintenance is done by the owner himself. The normal maintenance of the vehicle is related to the service life of the vehicle and the safety of the driver and passengers. Improper maintenance or use will cause vehicle failures and bring safety hazards. In addition to going to our maintenance station on time for mandatory maintenance, you should also do your daily maintenance work, which is beneficial to the "health" of the vehicle. Maintaining a good driving condition of the car benefits from meticulous daily maintenance.

After purchasing the car, please read carefully the "Product Quality Assurance" and "Instruction Manual" that came with the car. There are detailed use precautions and maintenance methods in the "Instruction Manual". You should read and follow them carefully to ensure that the vehicle is in Good use condition. Introduce the common sense of vehicle maintenance and hope to provide you with some help.Car paint maintenance

The common sense of car paint maintenance is actually very complicated. Although the paint looks smooth, there are small concave surfaces and holes on the surface. It is recommended that a new car be sealed or coated. In general, the coating time is longer than the sealing time. The sealing effect is about 3 months to half a year, and the coating is more than half a year. It is recommended that a second sealing or coating is required after a certain period of time. The usual items in car wash shops are polishing and waxing. But these two items should be done under the premise of coating or sealing, because always waxing or polishing is equivalent to consuming the thickness of the paint surface, gradually making the paint thinner, tarnishing, and small scratches appear.

There are also many things that need to be paid attention to in the daily maintenance of car paint. First, avoid directly wiping the paint with a duster or dry cloth. After washing off the dust and dirt on the surface of the car, wipe it with a clean absorbent cloth. Do not dry it yourself after flushing. Second, when parking, you should consider avoiding long-term sunlight, especially white and non-metallic paint. Third, reduce the number of car washes and try not to wax and polish the car. Fourth, pay attention to timely removal of corrosive things such as bird droppings. Fifth, pay attention to reducing to more corrosive areas when driving, such as the seaside, the road surface with snow melting agent, the newly paved asphalt road, etc. Sixth, after running the highway in summer, the carcass of insects hit by the front of the vehicle should be cleaned in time. If it is not cleaned in time, the paint surface of the vehicle will be corroded in a short time.

  • Car tire maintenance

Car tires and steel rims are the most dirty parts. Therefore, the maintenance of tires is also a very important key. Before washing the tires, prepare a brush with a long handle. If the tires are not too dirty, just wash them with a common detergent. Unless there is really too much dirt, you may have to buy professional cleaners.

Brushes cannot be used on chrome-plated mirror-treated wheels, which will leave obvious scars. Chrome-plated wheels generally use sponges, and then consider using brushes for small areas.As long as the tires and the parts below the knee are cleaned, the whole car will look bright and beautiful

Leather protection: a complete set of leather care tools, select different tools for different parts. Steam sterilization: professional steam sterilization performs comprehensive high-temperature sterilization on the air in the car, air conditioning outlets, seats, and floor velvet. Instrument control panel: You can use a brush to clean the instrument panel, air-conditioning air inlets, switches, buttons, etc. every day. After cleaning, you can spray a layer of panel wax. Ceiling: Dust can be removed with a car vacuum cleaner.

The fourth is to regularly use leather cleaners and maintenance agents for cleaning and maintenance. Floor velvet: usually put a foot pad on the floor velvet to facilitate daily cleaning.

  • Car functional parts maintenance

1. Engine oil inspection

Park the vehicle on a level road. Pull out the vernier to check the oil level. If the oil is within the two marking lines (F) and (L), it belongs to the normal range, and if it is lower than the (L) position. The specified type of engine oil should be added, and the liquid level after refueling cannot be higher than (F) level.

2. Engine coolant level inspection

Never open the radiator cover when the engine is in a warm state, otherwise you may be scalded by the spilled coolant or high-temperature steam. After the engine is cooled, check that the liquid level of the coolant should be between the full level and the low level. Otherwise, distilled water or pure water (mineral water can not be added) or refrigerant should be added. The height of the liquid level after adding water should not exceed the full level. If it is found that the cooling fluid decreases rapidly in a short period of time, check the cooling system for leaks or go to the maintenance station for inspection.

3. Inspection of brake fluid level

If the brake is also between the high and low positions, it means normal. If the brake fluid is close to the lower limit or lower than the lower limit, it means that there may be a leak in the system or excessive brake shoe wear. You should go to the repair station for maintenance in time.

When adding brake fluid, pay attention to adding the same type of brake fluid to prevent damage to the cup, and pay attention to protect the paint to prevent corrosion of the paint surface.

Fourth, check the liquid level of the clutch master cylinder

If the fluid level of the clutch is between the high and low fluid levels, it means it is normal. If it is lower than the standard line, the master cylinder or the sub-cylinder cup may be damaged. When the engine is running, it will be difficult or impossible to shift gears. Please go to the nearest maintenance station for maintenance immediately.

5. Maintenance and inspection of battery

Check whether the battery is firmly fixed, the electrolyte should be between the upper limit and the lower limit, and the electrolyte or distilled water should be added to the upper line in time when it is close to the offline. Keep the positive and negative cables of the battery in good contact, and keep the battery clean and dry. For vehicles that have been stored for a long time, remove the positive and negative cables of the battery, and re-wire the battery after about half a month. After starting the engine for about 20 minutes, charge it in time if the battery is obviously insufficient.

Six, tire inspection

The tire pressure should be checked at room temperature every month. If it is lower than the normal standard, the tire pressure should be refilled in time. The air pressure cannot be too high or too low, otherwise it will affect the safety of driving.

Check the tires for cracks, and replace the tires in time when there is a safety hazard.

When choosing tires, make them the same model.

Seven, belt inspection

When starting the engine or driving the vehicle in normal times, the belt sounds. One situation is that the belt has not been checked and adjusted for a long time, and it can be adjusted according to normal standards. Another situation is that the belt is aging and needs to be replaced.

8. Inspection of the air filter

If the air filter is too dirty, it will cause poor engine operation, excessive fuel consumption, damage to the engine, etc. When checking the air filter, if there is less dust and lighter blockage, you can use high-pressure air to blow it from the inside to the outside and continue using it. The dirty air filter should be replaced in time.

Nine, spark plug inspection

Normal spark plug insulation ceramics are intact. There is no rupture and leakage phenomenon. When the spark plug gap is 0.8+-0.0mm, the spark is blue and strong. If an abnormality is found, the gap should be adjusted or the spark plug should be replaced.

10. Check the gasoline filter

If you find that the fuel supply is not smooth, check whether the gasoline filter is clogged, and replace it in time if the foreign matter is clogged.
