What does it mean when the cruisemain light is on?
2 Answers
cruisemain light indicates that the vehicle's cruise control mode is activated. This system can only be engaged when the vehicle speed exceeds 40 km/h. During highway driving, after setting the desired speed, you can release the accelerator pedal, and the vehicle will maintain a constant speed. Some high-end models' cruise control systems feature automatic trajectory recognition and obstacle avoidance capabilities. For instance, when going uphill or downhill, the cruise control system can automatically compensate to maintain a relatively constant vehicle speed. Cruise control is also known as speed control system or autonomous driving system. Its function is to automatically maintain the set speed without requiring the driver to press the accelerator pedal, allowing the vehicle to travel at a fixed speed.
When I was driving, I noticed the cruisemain light was on, which is usually a sign that the cruise control system is activated, indicating the system is in operation. However, if the cruise button light comes on accidentally and everything else is normal, it's fine; but if it lights up when it shouldn't, there might be a problem, such as a faulty speed sensor, brake light switch issue, or damaged control module. I encountered this situation on the highway—the light came on and the car had trouble accelerating. It turned out to be a loose sensor connection, which was easily fixed by securing it. My advice is to first try manually turning off the cruise control system. If the light remains on, go to a repair shop for a check-up immediately. Don’t underestimate it, as it could be a hidden issue affecting driving safety. Always pay attention to dashboard warnings, and regular maintenance can prevent many minor problems.
