Adaptive cruise control (ACC) is an advanced driver assistance system that automatically adjusts your speed to maintain a safe following distance. Learning how to use it correctly can make your journeys smoother and reduce stress.
- Understand how ACC works – It uses radar or cameras to monitor traffic and adjust your speed.
- Read your vehicle’s manual – Each car has different settings and buttons; check the manual before using ACC.
- Set a safe following distance – Many systems allow you to choose the gap; start with a longer distance and adjust as you gain confidence.
- Keep your hands on the wheel – ACC does not steer the vehicle; you need to remain in control.
- Stay alert and watch the road – Always be prepared to brake or cancel ACC if road conditions change.
- Do not use ACC in bad weather or heavy traffic – Rain or fog can reduce sensor accuracy; in these conditions, drive manually.
- Keep sensors and cameras clean – A dirty radar sensor or camera can cause false readings; check them regularly.
- Regularly check for software updates – Manufacturers release updates to improve performance and safety.
- Disable ACC when towing or carrying heavy loads – Extra weight affects braking distances; manual control is safer.
- Practice in a quiet area – Try ACC on a quiet road to understand how it responds to changes in speed.
Adaptive cruise control can enhance your driving experience when used correctly. Take time to learn its features and always stay attentive. For more plain‑English guides and tips, visit our Driver’s Lounge.
