Urgency: Moderate
Tire Pressure Warning Light (TPMS)
Investigate soon. Driving short distances is generally okay, but book a diagnostic check.
What the Tire Pressure Warning Light (TPMS) Means
On the your car, this symbol means the tire pressure monitoring system detected low pressure. It is often triggered by cold weather or a slow leak, and occasionally by a failing TPMS sensor.
Common Causes
- Cold weather lowering pressure
- Slow puncture or nail
- Under-inflation over time
- Failed TPMS sensor battery
- Recent tire rotation not relearned
How to Fix It
- Check all four tire pressures with a gauge when cold
- Inflate to the placard value (door jamb sticker)
- Inspect for nails or damage if one tire keeps dropping
- Drive to let the system re-read, or perform the TPMS relearn
- Replace a failed sensor if the light flashes then stays on
