How to Deal with the Illuminated Triangle Exclamation Mark in a Car?
2 Answers
When the triangle exclamation mark in a car is illuminated, the proper handling method is to stop the vehicle immediately for inspection and repair. This light is a drive force indicator warning light, and the reasons for its illumination include: 1. Overheating of the dry dual-clutch transmission clutch; 2. Intervention or malfunction of the fuel cut-off system; 3. Faulty parking sensors; 4. Malfunction of external lights; 5. Engine oil pressure sensor failure; 6. Warning or malfunction of the traction control system. The working principle of the traction control system is: it uses a computer to detect the speed of the wheels and the steering angle of the steering wheel. When the car accelerates, if the computer detects an excessive speed difference between the drive wheels and non-drive wheels, it will send a command signal to reduce the engine's fuel supply, thereby decreasing the driving force.
I've been driving for twenty years, and the common triangle exclamation mark light often alerts the owner to potential risks, such as insufficient tire pressure or brake system issues. My approach is to immediately pull over to a safe spot, turn on the hazard lights, and after turning off the engine, check the dashboard for any detailed information displayed. For instance, once on the highway when the light came on, the display showed 'Check Tire Pressure,' so I drove to a service station to inflate the tires, which resolved the issue. Another time, it displayed 'Brake Failure,' so I promptly contacted a tow truck to take the car to a repair shop, where they found the brake pads were worn and needed replacement. To prevent such problems, I've developed the habit of regularly checking the tires and brakes—measuring tire pressure monthly to keep it within the proper range and visiting a professional workshop every six months for maintenance and error code scans. I always keep a tire pressure gauge and basic tools in the car to handle minor issues myself and avoid last-minute panic. On the road, safety comes first—never delay addressing any problems.
