Distance Alert* limitations

Distance Alert uses the same radar sensor as Adaptive Cruise Control* and has several limitations.

 Warning

  • The radar sensor has a limited field of vision. In some situations it may detect a vehicle later than expected or not detect other vehicles at all.
  • The radar sensor cannot cover all driving situations and traffic, weather and road conditions.
  • The driver is responsible for maintaining a safe distance and speed and must intervene if the various driver support systems do not maintain a suitable speed or suitable distance to the vehicle ahead.
  • Maintenance of radar sensor components may only be performed by a trained and qualified Volvo technician.
  • Strong sunlight, reflections from the road surface, strong lighting contrasts or using sunglasses may make the warning light in the windshield difficult to see.

 Warning

  • Poor weather or winding roads can affect the radar sensor's capacity to detect vehicles ahead.
  • A vehicle's size (e.g., a motorcycle) can also affect the radar sensor's capacity to detect another vehicle. This may result in the warning light illuminating at a shorter distance than the one that has been set or not illuminating at all.
  • High speeds may also result in the warning light illuminating at a shorter distance than the one that has been set due to limitations in the radar sensor's range.
