What is the reason for the car SET light being on?
1 Answers
Car SET light being on is caused by abnormal tire pressure. Many vehicles nowadays are equipped with a tire pressure monitoring system. When the sensors detect abnormal tire pressure, it will alert the driver on the dashboard to check the tires. In some vehicles, the SET button on the center console will also light up simultaneously. In such cases, you should immediately stop to check if there is any air leakage in the tires. If the tires are underinflated, you need to replace them with the spare tire before continuing to drive, and should not continue driving. The tire pressure set in summer should be slightly lower than in winter because the road surface temperature is very high in summer, and the tire temperature also increases while driving, causing the gas inside the tires to expand. If the tire pressure is too high in summer, it significantly increases the risk of a tire blowout. In winter, the tire pressure can be set a bit higher because the cold air causes the tire pressure to display slightly lower than usual.
