1. The first guarantee is very important
New car maintenance should be sufficient. Most car owners will go to special service stations to do maintenance according to the manufacturer's regulations when the first warranty period is reached, because most car manufacturers have implemented a free oil change discount for new cars. For example, Shanghai GM will provide 4 free engine oil and oil filter replacement services during the quality guarantee period. However, there are also a small number of car owners who neither consult the staff nor read the "Maintenance Manual", so there are also examples of missing the first insurance. Since it is a new car, if the car owner misses the first warranty, it will only cause the oil to turn black and dirty, which will not cause any serious consequences. However, experts suggest that car owners should take the first insurance, because the new car is in a running-in state, and the running-in of mechanical parts will have a relatively high demand for lubricating oil. This is the significance of the first insurance.
2. The second guarantee is also important
Relatively speaking, the second guarantee is very important to replace the brake pads for 40,000 to 60,000 kilometers. The project involves the inspection and maintenance of eight parts including engine, automatic transmission, air-conditioning system, steering system, braking system, suspension system, body parts, tires, etc., as many as 63 items. In addition, it also includes quality inspection and test run. It can be seen that after so many inspections and maintenances of the car, the overall condition of the car will obviously enter the best state, and the safety of driving can be best guaranteed.
3. Key items for maintenance
(1) Brake pads
Generally speaking, brake pads need to be replaced when the vehicle has traveled 40,000 to 60,000 kilometers. For car owners with bad driving habits, the replacement schedule will be shortened accordingly. For example, when a car owner sees a red light ahead, he refuels instead of refueling, and then waits for the green light to release by dragging the brakes, which belongs to this kind of habit. In addition, if the main car is not maintained, it is impossible to find that the brake pads are thinned or completely worn out in time. If the worn brake pads are not replaced in time, the braking force of the vehicle will gradually decrease, threatening the safety of the owner, and the brake disc will also be worn out, and the maintenance cost of the owner will increase accordingly. Taking Buick as an example, if the brake pads are replaced, the cost is only 563 yuan, but if the brake disc is also damaged, the overall cost will reach 1081 yuan.
(2) Tire rotation
Pay attention to the tire wear mark. Among the tire maintenance items of the second warranty, one of them is tire rotation. When using a spare tire in an emergency, the owner should replace it with a standard tire as soon as possible. Because of the particularity of the spare tire, Buick does not use the method of circular transposition between the spare tire and the tire of other models, but the four tires are diagonally transposed. The purpose is to make the wear of the tire more even and prolong its service life. In addition, tire maintenance items also include adjusting air pressure. Car owners should not underestimate the tire pressure. If the tire pressure is too high, it is easy to wear the middle of the tread. It is worth reminding that if the tire pressure is measured without the help of a barometer, it is difficult for the owner to visually measure it accurately. There are still some details in the daily use of tires. If you pay attention to the distance between the tread pattern and the wear mark, generally speaking, you should replace the tire if the distance is within 2-3mm. Another example, if the tire is punctured, if it is on the sidewall, the car owner must not listen to the advice of the quick repair shop to repair the tire, but should replace the tire immediately, otherwise the consequences will be serious. Because the sidewall is very thin, it will not be able to withstand the weight of the vehicle after repairing, and it is prone to puncture.
Prevention is the priority, combined with prevention and control, and standardized maintenance is done in accordance with the maintenance manual. That way the truck won't have major problems.
