What does a circle with an exclamation mark mean?

[SanAngelo]

A circle with an exclamation mark refers to the tire pressure monitoring indicator, which indicates insufficient tire pressure. The method to clear the tire pressure monitoring indicator is: 1. Turn on the ignition switch and use the remote control to unlock three times; 2. Simultaneously press the unlock and lock buttons until the horn sounds twice, then release; 3. Release the air pressure from one tire. Each time air is released from a tire, the horn will sound once. After the horn sounds four times, refill the tire pressure to the normal level. The hazards of low tire pressure include: 1. Increased road friction coefficient and higher fuel consumption; 2. Heavy steering wheel, prone to deviation, which is not conducive to driving safety; 3. Increased movement of various parts of the tire, excessive rolling leading to abnormal tire heating; 4. Reduced performance of the cord and rubber, cord breakage and separation between layers or excessive friction with the rim, causing damage to the tire bead and abnormal wear.

I've been driving for twenty years, and the moment I see that yellow circle with an exclamation mark on the dashboard, I know what's up. It usually means there's an issue with the tire pressure. Maybe one of the tires has been punctured, or the pressure is too low. You definitely can't take this lightly—driving too fast could cause the tire to deform or even blow out. Immediately find a safe spot to pull over, check the standard tire pressure listed on the door frame with your phone, and then inspect all four tires for obvious leaks. Just last week, I had this happen, and it turned out the right rear tire had a slow leak from a nail. If you're really unsure, call for roadside assistance—don't risk driving further.

Yesterday, while taking my child to school, a yellow warning light shaped like a circle with an exclamation mark suddenly lit up on the dashboard, which was quite noticeable. After asking a friend, I learned it was the tire pressure warning signal, so I immediately pulled over to check the tires. It turned out there was a small crack on the sidewall of the right front tire causing a slow leak—fortunately, I caught it early. Neglecting tire pressure not only poses a driving hazard but also increases fuel consumption. Now that the weather is getting colder, tire pressure tends to drop more easily. That’s why I recommend keeping a compact tire pressure gauge in the car for regular checks. Get into the habit of testing the pressure before refilling each month to avoid such situations.

This indicator represents a tire pressure monitoring system warning. It is recommended to first check which tire is abnormal and try adding some air using the onboard air pump. If the warning light does not disappear within five minutes, go to a repair shop immediately. Remember, driving with this light on can cause significant damage to the tires.

The yellow warning light with an exclamation mark inside a circle on the dashboard indicates abnormal tire pressure. It may flash briefly during vehicle startup self-check, which is normal, but if it stays on continuously, it means one of the tires has either too low or too high pressure. Last time, it was found that the left rear tire was 30 kPa below the standard pressure, caused by a slow leak. The vehicle's sensors are very sensitive and may give false alarms during sudden temperature drops, but for safety, you should immediately slow down and check the tire pressure. Some vehicles have a dedicated reset button in the trunk to temporarily turn off the warning. In such cases, never drive on highways as it can be dangerous.
