The radar sensor and its limitations

In addition to being used by ACC, the radar sensor is also used by Distance Alert (see page 164) and Collision Warning with Full Auto-brake and Pedestrian Detection (see page 172). This sensor is designed to detect cars or larger vehicles driving in the same direction as your vehicle, in the same lane.

The radar sensor's capacity to detect vehicles ahead is impeded:

• if the radar sensor is obstructed and cannot detect other vehicles, for example in heavy rain, or if snow or other objects are obscuring the radar sensor.

• if the speed of vehicles ahead is significantly different from your own speed.
