What does it mean when the low-pressure run-flat indicator is activated?
3 Answers
The activation of the low-pressure run-flat indicator indicates that the air pressure in at least one tire differs from the pressure recorded during the last tire reset, and it is necessary to check the tire pressure of the vehicle. Below are the methods for resetting the low-pressure run-flat indicator: 1. Adjust the tire pressure: When the tire pressure is insufficient, the dashboard will prompt to reactivate the low-pressure run-flat indicator. Adjusting the tire pressure can reset the low-pressure run-flat indicator. 2. If adjusting the tire pressure does not reset the low-pressure run-flat indicator: Press the right arrow button on the steering wheel to navigate to the maintenance menu, then press the down button to reset the tire pressure light.
Last time I was driving on the highway, suddenly that run-flat indicator light on the dashboard came on, and I felt my heart rate spike. When this thing activates, it means the tire pressure is too low, possibly due to a leak or flat, but the car can still keep going for several dozen kilometers, like 50 to 80 km, allowing you to safely reach the nearest repair shop or gas station. That time, I immediately slowed down to under 80 km/h and carefully drove to the service area to check, only to find a nail had punctured the tire. Thankfully, this system helped avoid the danger of being stranded on the road. Now I've made it a habit to check the tire pressure before heading out to prevent this from happening again. Safety comes first when driving—never take it lightly when this indicator activates, and deal with it promptly to avoid completely ruining the tire.
When the low-pressure run-flat indicator on the car activates, it indicates insufficient tire pressure but the vehicle can still travel a certain distance. I recommend immediately reducing speed to the recommended level, typically 70-80 km/h, and avoiding aggressive driving or sharp turns. Then, find a safe location to inspect the tire, such as a repair shop or 4S dealership. The activation may be due to the tire pressure monitoring system detecting a leak, triggering the run-flat function to maintain stability. In such situations, stay calm, turn on the hazard lights to alert vehicles behind you, and avoid stopping on the roadside to change the tire, which increases risk. Develop good habits by using a tire pressure gauge to check the pressure monthly to prevent low-pressure issues. With proper maintenance, tires will last longer and be safer.
