What to Do When the Car Tire Pressure Warning Light Comes On?

[Quinn]

Here are the steps to handle a car tire pressure warning: 1. Pull over safely: When the tire pressure warning light comes on, first turn on the hazard lights, slow down gradually, and after ensuring it is safe, pull over to the right side of the road. If you are on a highway, try to stop in the emergency lane and set up a safety warning sign 150 meters behind the vehicle. 2. Rule out false alarms: Tire pressure monitoring systems work in two ways: active and passive. Active systems trigger an alarm when the tire pressure is too low or there is a leak, based on preset pressure values. Passive systems monitor tire pressure by detecting tire rotation speed, as underinflated tires rotate faster than normal ones. There are four common reasons for a tire pressure warning: a punctured or leaking tire; not resetting the tire pressure settings after changing or repairing a tire; not resetting the tire pressure settings after inflating the tires; or the car being parked for a long time without use. Therefore, it is advisable to conduct a self-check first. 3. Change the tire or call for assistance: If the tire pressure continues to drop after the above checks, exit the vehicle to inspect the faulty tire. During this time, keep the hazard lights on, wear reflective clothing, and ensure a safety warning sign is placed at a safe distance behind the car. If you find the tire is leaking or damaged, you can use the car's jack to replace it with the spare tire.
