Understanding the PRESAFE Alert
The Purpose of PRESAFE
Mercedes’ PRESAFE system is engineered to enhance occupant safety by taking precautionary measures when an imminent collision is detected. It initiates actions such as tightening seat belts, adjusting seat positions, and closing windows to prepare the vehicle and its occupants for an impact.
Causes of Persistent PRESAFE Alerts
While the PRESAFE system is crucial for preemptive safety, a persistent alert can be triggered by various factors, such as sensor malfunctions, system errors, or issues with the vehicle’s components.
