How to adjust Collision Avoidance System alert distance on Honda Accord

The Collision Mitigation Braking System or CMBS is designed to alert drivers when it detects a potential frontal collision, and if one is imminent: to apply the brakes to mitigate the severity of a possible impact.

When a potential frontal collision is detected, the system is designed to issue a visual alert in the instrument panel as well as a beeping noise. CMBS uses a radar unit mounted at the front of the vehicle and a windshield mounted camera to gauge the distance of a detected vehicle ahead.

The radar unit is positioned directly below the front license plate position you can adjust the system to issue the alerts when the detected vehicle is either farther away or closer to your vehicle.
