● The sensor generally detects the signals returned from the reflectors on a vehicle ahead. Therefore, the system may not function properly under the following conditions: - When the reflectors of the vehicle ahead are positioned high or close to each other (including a small vehicle such as motorcycles). - When the sensor gets dirty or it is impossible to detect the distance from the vehicle ahead. - When the reflectors on the vehicle ahead are missing, damaged or covered. - When the reflectors of the vehicle ahead are covered with dirt, snow or road spray. - When visibility is low (such as rain, fog, snow, etc.). - When snow or road spray from traveling vehicles is splashed. - When dense exhaust or other smoke (black smoke) from vehicles reduces the visibility of the sensor. - When excessively heavy baggage is loaded in the rear seat or the luggage room of your vehicle. - When abruptly decelerating. accelerating or - On a steep downhill slope or on roads with sharp curves. - When there is a highly reflective object near the vehicle ahead (i.e., being very close to another vehicle, signboard, etc.) - When you are towing a trailer. ● Depending on certain road conditions (curved or beginning of a curve), vehicle conditions (steering position or vehicle position), or the preceding vehicle's conditions (position in lane, etc.), the system may not function properly. The system may detect highly reflective objects such as reflectors, signs, white markers, and other stationary objects on the road or near the traveling lane and provide unnecessary warning. ● The system may not function in offset conditions. ● The system may not function when the distance to the vehicle ahead is extremely close. ● The system is designed to automatically check the sensor's functionality. If the sensor is covered with ice, a transparent or translucent plastic bag, etc., the system may not detect them. In these instances the system may not be able to warn the driver properly. Be sure to check and clean the sensor regularly. ● Excessive noise will interfere with the warning chime sound, and the chime may not be heard. ● A sudden appearance of a vehicle in front (i.e., it abruptly cuts in) may not be detected and the system may not warn the driver soon enough. ● The system will be cancelled automatically with a beep sound and the IBA OFF indicator light will illuminate under the following conditions: - When the sensor window is dirty - When the system malfunctions Starting and driving 5-75
