What does the off light on the dashboard mean?

The yellow off light on the car dashboard means off, and ON means on. The off light on the car mainly refers to ESPOFF. ESP stands for the Electronic Stability Program, which is an active safety device mainly used to prevent the risk of vehicle skidding and fishtailing. If the ESPOFF light on the car dashboard lights up, it means that the vehicle's electronic stability control system is turned off or has malfunctioned. If you accidentally press the ESPOFF button on the vehicle, you can turn the ESP back on by pressing it again briefly. If the ESPOFF light is on due to a system malfunction, it should be sent to a 4S shop for repair in time. There are many reasons for the malfunction light to come on, such as circuit failure, sensor damage, electronic control unit signal error, battery power loss, etc. ESP is particularly sensitive to oversteer or understeer. For example, when the car turns left too sharply (oversteer) on slippery roads, it will fishtail to the right. The sensor will sense the skid and quickly brake the right front wheel to restore traction, creating an opposite torque to keep the car in the original lane. The difference between a car with ESP and one with only ABS and ASR is that ABS and ASR can only react passively, while ESP can detect and analyze the vehicle condition and correct driving errors, preventing problems before they occur.
I've been driving for over a decade and have seen many dashboard warning lights. That 'OFF' light usually means the Electronic Stability Control (ESC) system is deactivated. This system automatically prevents wheel slippage on slippery roads to maintain vehicle stability, and it's generally safe to keep it on. If you manually turned it off by pressing the button, like when trying to get unstuck in mud, then it's fine. But if the light comes on without manual operation, there might be a system malfunction, such as a faulty sensor, blown fuse, or wiring issue. I remember once during rainy highway driving when the light suddenly illuminated—I promptly pulled over, and later inspection revealed a loose connector causing poor contact. My advice: don't ignore this warning. Try restarting the car to see if it resets; if the issue persists, definitely visit a professional repair shop for diagnosis. Driving with ESC disabled increases the risk of losing control, especially in rain or snow. Addressing it promptly saves hassle, and repair costs are usually low—just basic circuit checks. Safe driving is what matters most.
