What does the yellow triangle exclamation mark on the dashboard mean?
2 Answers
The yellow triangle exclamation mark on the dashboard is the traction control indicator, also known as the ground grip control system indicator. The functions of the yellow triangle exclamation mark on the dashboard are: 1. To remind the driver to turn off the traction control system; 2. If this light stays on while the traction control system is active, it indicates a problem with the TCS. The reasons for the yellow triangle exclamation mark on the dashboard lighting up include: 1. Overheating of the dry dual-clutch transmission clutch; 2. Intervention or malfunction of the fuel cut-off system; 3. Parking sensor failure; 4. External light failure; 5. Engine oil pressure sensor failure; 6. Traction control system warning or malfunction.
Every time I receive customers at the auto repair shop, I encounter inquiries about the yellow triangle exclamation mark light on the dashboard. That light is actually a universal warning symbol, indicating that the vehicle system has detected a non-emergency issue requiring attention, such as low tire pressure, a brake system malfunction, or abnormal electrical sensors. Common triggers include low fuel levels, unstable battery voltage, or ABS system problems. If this light comes on while driving, it is recommended to pull over immediately for a safety check and refer to other dashboard icons for additional clues—for example, if accompanied by the tire pressure light, it likely indicates a tire leak, and it’s best not to drive further to avoid risks. Regular vehicle maintenance, especially battery and sensor checks, can help prevent such warnings from appearing prematurely. My experience shows that many car owners ignore this light, leading to worsening problems and higher repair costs for replacement parts.
