Radar sensor
The radar sensor is designed to help detect cars or larger vehicles driving in the same direction as your vehicle, in the same lane.
The radar sensor and its limitations
In addition to being used by the Adaptive Cruise Control (ACC), the radar sensor is also used by Distance Alert (see Distance Alert – introduction) and Collision Warning with Full Auto-brake and Pedestrian Detection (see Collision warning – introduction).
Warning
- If there is visible damage to the front grille or you suspect that the radar sensor may be damaged in any way, contact a trained and qualified Volvo service technician as soon as possible. The radar sensor may only function partially (or not at all) if it is damaged or is not securely fastened in place.
- Accessories or other objects, such as extra headlights, must not be installed in front of the grille.
- Modification of the radar sensor could make its use illegal.
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.
Note
Keep the area in front of the radar sensor clean.
- if the speed of vehicles ahead is significantly different from your own speed.
