ADVANCED PARKING GUIDANCE SYSTEM D Tips for setting the target parking position Useful information for setting the target parking position (green frame) THE DISPLAY POSITION OF THE GREEN FRAME The system decides the initial positioning of the green frame by the position of the parking space detected by the front side sensors or the position of the vehicle when it stops, and by detecting the white lines of the parking space in the camera image to identify the parking space location. The front side sensors identify the parking space location and the white lines near that location are detected. The front side sensors cannot identify the parking space location, or the parking space location may be misaligned in the following situations. D A vehicle is parked at the back of the parking space or the sensors cannot detect a parked vehicle due to vehicle shape etc. D The sensors cannot detect a pole or wall beside the parking space. D The sensors detect a pedestrian or object near the parking space. If there are no vehicles parked on either side of the target parking space when your vehicle stops, the approximate parking space location is identified, and the white lines in that location are detected. For this reason, stopping in front of the parking space will make the detection of target parking space's white lines easier. Successful detection of the parking space's white lines may not be possible, depending on the shape of the line. 8. Once the vehicle is mostly within the target parking position, voice guidance will give a message, and parking assist mode will finish. For safety, voice guidance is given slightly before the target parking position. Furthermore, at that point system control will finish, so grip the steering wheel firmly, and finish parking in the desired position, using the brake to control the vehicle's speed. Check in front and behind the vehicle visually and check with the mirrors while backing up. 240
