Troubleshooting and remedial action
If a message is displayed in the instrument panel saying that the camera/radar sensor is blocked, City Safety cannot detect vehicles, cyclists or pedestrians ahead of you, which means that the system is not functioning properly.
However, this message will not be displayed in all situations in which the camera/radar sensor is obstructed. For this reason, the driver must ensure that the area of the windshield in front of the camera/radar sensor is always kept clean.
| Cause | Action |
|---|---|
| The area of the windshield in front of the camera/radar sensor is dirty or covered by ice or snow. | Clean the windshield or remove the ice/ snow. |
| Thick fog or heavy rain/snow blocks reduces the camera/radar sensor's range of visibility. | No action. The driver should be extra alert in conditions of this type. |
| There is dirt between the inside of the windshield and the camera/radar sensor. | Have the area of the windshield cleaned by a trained and qualified Volvo service technician. |
Important
- Service and maintenance on City Safety may only be carried out by a trained and qualified Volvo service technician.
- If a crack, scratch or stone chip should occur in the section of the windshield in front the camera/radar sensor, contact a trained and qualified Volvo service technician to repair or replace the windshield. Failing to do so may result in reduced City Safety functionality.
- This can also result in certain functions being reduced or disabled, or they may respond incorrectly.
- Volvo recommends that cracks, scratches or stone chips on the windshield in front of the camera/radar sensor should not be repaired; in such cases, the entire windshield should be replaced.
- Before the windshield is replaced, contact a Volvo retailer to ensure that the correct windshield is ordered and installed. If the wrong type of windshield is used, this may cause City Safety to function improperly or not at all.
- Volvo recommends the use of only Genuine Volvo Replacement Windshields.
- When replacing windshield wipers, use the same type or ones approved by Volvo.
After the windshield has been replaced, the camera/radar sensor will have to be recalibrated by a trained and qualified Volvo service technician to help ensure proper function of all of the vehicle's camera-/radar-based systems.
Maintenance
In order for City Safety to function properly, the area of the windshield must be kept free of dirt, ice, snow, etc.
Other vehicle functions
If a message is displayed in the instrument panel, this means that the other systems using the camera/radar sensor (see the list below) will not have full functionality or may not function at all.
Do not mount or in any way attach anything on the windshield that could obstruct the camera/radar sensor.
Warning
- The camera has the same type of limitations as the human eye, i.e., it cannot see as well in heavy snowfall or rain, thick fog or in heavy blowing dust or snow. In such conditions, systems depending on the camera may experience greatly reduced functionality or may be temporarily deactivated.
- Never place any objects, decals, etc., on the windshield in front of the camera. This could reduce or block the camera’s function, and could cause one or more of the systems that utilize the camera to stop functioning.
- Strong sunlight, reflections from the road surface, ice or snow covering the road, a dirty road surface, or unclear lane marker lines may drastically reduce the camera’s capacity to detect the side of a lane, a pedestrian, a cyclist or another vehicle.
Radar sensor for other functions
City Safety uses the same radar sensor as Adaptive Cruise Control. See the article "Radar sensor limitations" for detailed information.
