The Side View Assist system is capable of registering objects three metres to the side and diagonally to the rear of the vehicle, covering the blind spot areas.
If the sensors detect a vehicle, their signal is first checked by the system's electronics to prevent false alarms. Then it can warn the driver in two ways: first optically, and then, if the driver fails to react, acoustically.
The Side View Assist system's ultrasonic sensors are mounted in the sides of the vehicle's front and rear bumpers. The two rear-side sensors monitor the blind spot on the lanes to the right and left.
The sensors use the same technique to detect parked vehicles, road signs and to register when drivers are passing other cars. In those cases, they do not set off an alarm. It is only when one of the rear side sensors reports an object that has not already been detected by the front sensors that danger is imminent.
The Side View Assist system works at speeds of between 10 and 140kph. Outside that range, it does not warn drivers. The system aids drivers in complex traffic situations when relative speeds are low, and therefore mostly helps them on urban roads and highways and on multi-lane roads where speed limits are in place. The system warns drivers but does not intervene directly in their actions.
