Starting and operating/BSD/RCTA (5–door models — if equipped) . In the following cases, the BSD/ RCTA will temporarily stop operating (or may stop operating) and the BSD/ RCTA warning indicator will appear. – When the radar sensor becomes significantly misaligned (If the orientation of the radar sensor is shifted for any reason, readjustment is required. Have the sensor adjusted at a SUBARU dealer.) – When a large amount of snow or ice sticks to the rear bumper surface around the radar sensors – When the vehicle is driven on a snow-covered road or in an environment in which there are no objects around (such as in a desert) for a long time – When the temperature around the radar sensors increased excessively due to long driving on uphill grades in summer, etc. – When the temperature around the radar sensors becomes extremely low – When the vehicle battery voltage lowers – When the vehicle battery becomes overvoltage When the above conditions are corrected, the BSD/RCTA will resume operation and the BSD/RCTA warning indicator will disappear. However, if the BSD/RCTA warning indicator has appeared for a prolonged time, have the system inspected at a SUBARU dealer as soon as possible. . The detectability of the radar sensors is restricted. The BSD/RCTA detection may be impaired and the system may not operate properly under the following conditions. – When the rear bumper around the radar sensors is distorted – When ice, snow or mud adheres to the rear bumper surface around the radar sensors – When stickers, etc. are affixed on the areas of the radar sensors on the rear bumper – During adverse weather conditions such as rain, snow or fog – When driving on wet roads such as snow-covered roads and through puddles . The radar sensors may not detect or may have difficulty detecting the following. – Small motorcycles, bicycles, pedestrians, stationary objects on the road or road side, etc. – Vehicles with body shapes that the radar may not reflect (vehicles 7-53 with a low body height such as sports cars or a trailer with no cargo) – Vehicles that are not approaching your vehicle even though they are in the detection area (either on a neighboring lane to the rear or beside your vehicle when reversing) (The system determines the presence of approaching vehicles based on data detected by the radar sensors.) – Vehicles traveling at significantly different speeds – Vehicles driving in parallel at almost the same speed as your vehicle for a prolonged time – Oncoming vehicles – Vehicles in a lane beyond the neighboring lane – Vehicles travelling at a significantly lower speed that you are trying to overtake . On a road with extremely narrow lanes, the system may detect vehicles driving in a lane next to the neighboring lane. – CONTINUED –
