The Reverse Traffic Detection (RTD) system is automatically disabled if any of the sensors become partially or completely obscured. The amber warning indicator dot illuminates in the door mirrors. The message Reverse Traffic Sensor Blocked is displayed in the message centre.
Check that there is nothing obscuring the rear bumper's surface and that it is clear from ice, frost, snow, mud, and dirt.
When a fault with a sensor is detected, an amber warning indicator dot illuminates in the door mirrors. The message Reverse Traffic Detection System Not Available is displayed in the message centre.
Even if the detected fault affects a radar sensor on only one side of the vehicle, the whole system is disabled. When the fault is temporary, the system operates correctly once the engine is switched off and then on again.
When a fault occurs that is not rectified when the engine is switched off and then on again, consult a retailer/authorised repairer.
