What Causes the Tire Pressure Monitoring Alarm in the New Sagitar?
2 Answers
The tire pressure monitoring alarm in the New Sagitar indicates abnormal tire pressure. Abnormal tire pressure is generally caused by the following three reasons: Abnormal tire pressure: The alarm will typically trigger if the pressure is below 1.8 bar or exceeds 3.0 bar. In this case, a tire inspection and pressure adjustment are required. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure is not reset promptly, the tire pressure monitoring system will still record the previous data, causing the tire pressure warning light to illuminate. Simply performing a tire pressure reset will resolve this issue. Damaged tire pressure sensor: The tire pressure sensor is used to monitor tire pressure and is directly installed inside the tire, connected to the tire inflation valve. If the sensor is damaged due to impact while driving, it can also cause the tire pressure warning light to turn on. For sensor damage issues, the only solution is to replace it with a new component.
When I first drove my new Sagitar, the tire pressure monitoring light came on. After checking, I found there could be several reasons: significant temperature changes, like in winter mornings when cold tires have lower pressure, can easily trigger the system's warning; or there might be a small nail causing a slow leak that went unnoticed, gradually dropping the pressure to dangerous levels. It could also be that the tire pressure sensor is faulty or the battery is dead, in which case I'd need to visit a repair shop for a replacement. I usually start by measuring the tire pressure of each wheel myself with a tire pressure gauge, comparing it to the recommended values on the door frame. If it's normal, I reset the system to see if it's a false alarm. Don't ignore it—low tire pressure can cause skidding during high-speed emergency braking and also significantly increases fuel consumption. Addressing it early ensures safety and peace of mind.
