City Safety – troubleshooting
Troubleshooting
If Windscreen Sensors blocked appears in the information display, this indicates that the City Safety™ laser sensor is obstructed in some way and cannot detect vehicles ahead of you, which means that the system is not functioning.
However, this message will not be displayed in all situations in which the sensor is obstructed. For this reason, the driver must ensure that the area of the windshield in front of the sensor is always kept clean.
The following table shows some of the situations that can cause the message to be displayed and suggested actions.
| Cause | Action |
|---|---|
| The area of the windshield in front of the sensor is dirty or covered by ice or snow. | Clean the windshield or remove the ice/snow. |
| The laser sensor's field of view is obstructed. | Remove the obstruction. |
Note
If a crack, scratch or stone chip should occur in the section of the windshield in front the laser sensor, contact a trained and qualified Volvo service technician to repair or replace the windshield (see the illustration showing the location of the sensor in City Safety – function). Failing to do so may result in reduced City Safety™ functionality.
To help prevent limited or reduced functionality, please also observe the following:
- Volvo recommends that cracks, scratches or stone chips on the windshield in front of the laser 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.
