UNDERSTANDING THE FEATURES OF YOUR VEHICLE 153 Rear Park Assist Warning Display The Rear Park Assist Warning Display, located in the headliner near the flipper glass, provides both visual and audible warnings to indicate the distance between the rear fascia and the detected obstacle. When the ignition is changed to the RUN/ON position, the warning display will turn ON all of its LEDs for about 1 second. Each side of the warning display has 6 yellow and 2 red LEDs. The vehicle is close to the obstacle when the red LED is ON. The system dimly illuminates the two outer most yellow LED's when it is ON and detecting no obstacles. The following chart shows the warning display operation when the system is detecting an obstacle: 3 Rear Park Assist Display
