If the yellow warning symbol illuminates and PARK ASSIST SERVICE REQUIRED is shown on the information display, this indicates that the system is not functioning properly and has been disengaged.

Consult a trained and qualified Volvo service technician.

CAUTION
In certain circumstances, the park assist system may give unexpected warning signals that can be caused by external sound sources that use the same ultrasound frequencies as the system. This may include such things as the horns of other vehicles, wet tires on asphalt, pneumatic brakes, motorcycle exhaust pipes, etc. This does not indicate a fault in the system.
