How to eliminate the yellow exclamation mark in Haval H6?

When a yellow exclamation mark appears on the car dashboard, there are 4 possible scenarios: general fault, automatic transmission fault, abnormal tire pressure, and lighting fault. Below is a detailed analysis of these 4 scenarios: General Fault: A triangle with an exclamation mark inside indicates that the car's general performance or components and functions have malfunctioned. Common issues include parking sensor failure, fuel cutoff system intervention or malfunction, external light failure, engine oil pressure sensor failure, etc. It is necessary to visit a 4S shop for inspection to identify the source of the fault. Automatic Transmission Fault: A yellow gear with an exclamation mark inside is the automatic transmission fault warning light, indicating a transmission fault or transmission lubricant level below the normal range. The transmission oil should be replaced promptly. Abnormal Tire Pressure: A horizontal line with an exclamation mark inside a bracket represents the tire pressure monitoring warning light. This light turns on when the car's tire pressure is too low. Check the tire pressure and restore it to the normal range. Lighting Fault: A yellow bulb with an exclamation mark is the lighting fault indicator, signaling a malfunction in the car's lights. Solution: Visit a 4S shop for inspection as soon as possible, or conduct a self-check focusing on commonly used bulbs such as turn signals, fog lights, and interior lights to identify the problem. There is also a red exclamation mark inside a circle with a bracket, which represents a brake system warning. This mainly indicates a brake system malfunction or low brake fluid level. The brake system should be inspected immediately to avoid accidents.
After driving for so many years, I've encountered the yellow exclamation mark warning light on the Haval H6 several times. It's usually nothing major, with 90% of cases being caused by low tire pressure. After parking, take out the tire pressure gauge, check all four tires, and inflate them to the value specified in the manual, typically around 2.2-2.5 BAR. After inflating, drive for a few minutes and the light should go off on its own. If the light remains on, it might be a faulty sensor or a false alarm; restarting the engine or disconnecting the battery for a few minutes can reset it. I recommend not ignoring it because sometimes this light also warns of insufficient brake fluid or minor engine issues—it could be dangerous if something happens on the highway. Regularly checking tire pressure yourself can save a lot of hassle; just use an inexpensive tire pressure gauge to measure it monthly. Once it becomes a habit, you're less likely to run into this kind of trouble.
I remember my friend's Haval H6 had this warning light before, mostly it's the tire pressure alert. It's quite simple to handle it yourself: find an air pump or go to a gas station, measure the tire pressure and fill it to the standard value. Usually, after inflating, driving a short distance will make the light go off. If there's no change, check if the brake fluid or coolant is below the marked line and try adding some. Some cars have more software bugs, and a power reset might solve the issue. I think as the car ages, the sensors are prone to aging, so it's good to clean the tire area more often when washing the car. If you don't understand, don't force it; check community forums on your phone or make a trip to the 4S shop. Spending a little money is always better than blind repairs, after all, safety comes first. It's always good to have an emergency tool kit in the car.
