When driving through a roundabout, the following precautions must be taken: Slow down: Reduce speed 50-100 meters before the roundabout and adjust speed according to traffic conditions. Merge appropriately: Observe the movement of vehicles already in the roundabout from the left and merge at an appropriate time, slowing down or stopping if necessary. Turn on the turn signal in advance: Activate the right turn signal before exiting the roundabout, paying attention to the movement of vehicles and pedestrians on the right.

New car running-in speed is generally 50-90km/h, with some models allowing slightly higher speeds, but not exceeding 110km/h. Below are the relevant details: Precautions during the running-in period: During the running-in period, avoid excessive engine load, prolonged driving, especially prolonged high-speed driving. Operate each gear gently, avoid sudden acceleration, and start or climb slopes smoothly, avoiding overly aggressive maneuvers. Speed and RPM for various running-in stages of a new car: For the first 500 kilometers of a new car, maintain a speed of 60-70 mph with RPM not exceeding 2200. From 500 to 1000 kilometers, during the mid-running-in period, keep speed at 90-100 km/h with RPM below 2500. From 1000 to 1500 kilometers, in the late running-in period, speed can be increased to below 120 mph with RPM not exceeding 3000.

What does the tire size 215/55/r17 mean?

215 represents the tire width of 215 millimeters; 55 indicates the aspect ratio, meaning the ratio of tire height to width is 55%; The letter denotes the tire structure, with R standing for radial tire; 17 signifies the applicable rim diameter of 17 inches. Below are the tire maintenance precautions and replacement criteria: Tire maintenance precautions: Maintain a safe distance when driving at high speeds to avoid unnecessary or frequent braking, which can reduce tire damage; Periodically and appropriately rotate the tires on the vehicle to ensure even wear; Front tires should preferably use tires with vertical tread patterns, while rear tires should opt for horizontal tread patterns; When tire wear reaches the tread wear indicator, replacement is necessary. Tire replacement criteria: Rubber has a certain lifespan. Under normal circumstances, car tires have a service life of about 3-5 years, as they are constantly exposed to wind, sun, and rain, leading to gradual aging of the rubber. Aged tires lose strength, so they should be replaced promptly upon reaching their service life.

What are the car maintenance items in summer?

Summer car maintenance items include enhancing paint surface care, preventing engine overheating, and avoiding placing flammable and explosive items. Below are detailed explanations: Enhancing paint surface care: Intense summer sunlight can cause significant damage to the car's paint surface. Additionally, rainwater and other debris falling onto the car can corrode and oxidize the paint. Therefore, it is essential to wash the car frequently and apply wax regularly. Preventing engine overheating: Preventing engine overheating is crucial. High temperatures, overloaded air conditioning, and malfunctioning cooling components can all affect the engine's heat dissipation. Moreover, prolonged vehicle operation and frequent starts and stops can increase friction among engine parts, leading to higher temperatures and worsening the cooling system's efficiency. Thus, it is important to conduct comprehensive checks on the car's cooling system regularly. Avoiding placing flammable and explosive items: Items such as lighters, power banks, batteries, oils, and chemicals should not be left in the car as they can explode when exposed to high temperatures.
