Distance Alert limitations1

Distance Alert functionality may be reduced in certain situations.

 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. 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.

 Note

The function uses the vehicle's radar unit, which has some general limitations – see the section "Radar unit limitations".
  1. 1 The Distance Alert function is only available in vehicles that can display information on the windshield with a head-up display.
