How does the driver activate the sensor

The driver activates the sensors by putting the vehicle in reverse. This activates the sensors that are installed on the front and back of the vehicle. In reverse, the sensors make a sound at a constant range and speed that lets the driver knows how far he or she is from the obstacle at the back of the vehicle. The closer you get to the obstacle while parking; the sensors will emit a longer and louder ranged sound.

The different sounding beeps will help the driver to determine whether the obstacle is in front or back of the vehicle. The front sensors have a high-sounding continuous beep to alert you of objects, while the back sensors give off a lower sounding beep for an alert.
