Approaching a vehicle ahead: When driving, the millimeter wave radar detects a vehicle ahead, and the system provides audible and visual warnings if it detects a risk of collision.

Closing on a vehicle ahead: The system applies light braking, and increases seat belt tension slightly to provide a tactile warning to the driver. The front passenger does not feel the tactile warning.

Collision unavoidable: The system actives strong braking, and securely tightens both the driver's and front passenger's seat belts to help reduce injury caused by the impact.
