Does the ACC warning light affect normal driving?

It's best not to drive. Below are the related reasons for ACC malfunction: 1. Light is on, but driver experiences no abnormalities: There are two scenarios when the warning light comes on. First, although the light is on, there are no unusual sensations while driving, with acceleration and braking functioning normally. In this case, the vehicle can still be driven normally. This might be due to a temporary sensor malfunction that has since resolved, interference from certain external conditions, or a fault that doesn't affect driving performance but may slightly impact emissions. In such situations, you can continue driving temporarily but should visit a repair shop for inspection as soon as possible. 2. Light is on with abnormal driving sensations: Second, when the warning light comes on accompanied by noticeable abnormalities such as severe shaking or weak acceleration, it's strongly advised not to continue driving. Call for roadside assistance or a tow truck instead. If the repair shop is very nearby, you may cautiously drive there. Since these symptoms indicate a serious malfunction, continued driving could worsen the problem, allow damage to accumulate, or even trigger additional failures. Therefore, continuing to drive is not recommended.
When the ACC warning light comes on, my first reaction as a car owner is that it doesn't affect the basic operations of normal driving. The car can still start, drive, brake, and steer—all core functions are operating normally. ACC, or Adaptive Cruise Control, is specifically designed to assist with automatic following distance and speed adjustment; the light simply indicates an issue with this auxiliary system, such as sensors being blocked by dirt or a software malfunction rendering it unusable. However, for everyday city driving, ACC isn't essential, and I can manually operate the throttle and brakes without any issues. That said, during long highway drives, its absence increases fatigue since it requires full concentration to maintain speed. I recommend first using the dashboard's self-diagnostic function to check for error codes, then visiting a repair shop to clear the fault codes. This is just from my experience—safe driving is far more important than relying on technology, and addressing issues early prevents them from escalating and affecting other electronic components.
I remember last month when the ACC warning light came on, I panicked a bit, but my friend told me not to worry as the car could still be driven normally. The ACC is just a convenience feature, and the light coming on means it's temporarily out of service, but the engine, steering, and brakes all function normally, not affecting daily commutes. It might just be that the camera or radar is dirty—try driving to a car wash and rinsing them off. However, in complex urban traffic conditions, without ACC, I had to focus more on pedal control to maintain distance and avoid rear-end collision risks. I immediately drove to get it checked and found it was just a loose connector, fixed within an hour. Overall, it's not a big issue, but prompt action is necessary to prevent minor faults from turning into major problems.
