What does it mean when the car's SET light is on?

[SpencerFitz]

When the SET light in a car is on, it indicates that the tire pressure is too low. Here is a detailed introduction to the SET light: 1. The SET light is part of the tire pressure monitoring system. 2. If the SET light is on, it means that the tire pressure in one of the wheels is too low. Please check the tire pressure, or there may be a system malfunction, in which case you should visit a Volkswagen dealership for assistance. Here is some additional information: 1. The tire pressure monitoring system automatically monitors the tire pressure in real-time while the car is in motion and alerts the driver to any leaks or low pressure to ensure driving safety. 2. Statistics show that tire blowouts account for up to 70% of severe traffic accidents, and insufficient tire pressure is the leading cause of all factors that can lead to a blowout.
