The RTD system automatically disables if any of the sensors become partially or completely obscured. The amber warning indicator dot illuminates in the exterior mirrors and the message Reverse Traffic Sensor Blocked appears in the Message centre.
Check that there is nothing obscuring the rear bumper and that it is clear from ice, frost, snow, mud, and dirt.
If a fault with a radar sensor is detected, an amber warning indicator dot illuminates in the exterior mirrors and the message Reverse Traffic Detection System Not Available displays in the Message centre.
Even if the detected fault affects the radar sensor on only one side of the vehicle, the whole system is disabled. If the fault is temporary, the system operates correctly once the engine is switched off and then on again.
If a fault occurs, consult a Retailer/Authorised Repairer.
