2005 Jeep Grand Cherokee Owner Manual - Page 129

UNDERSTANDING THE FEATURES OF YOUR VEHICLE 129 When the ignition is changed to the RUN/ON position, the warning display will turn ON all of its LEDs for about 1 sec. 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. When the obstacle is detected at a distance of about 59 inches (150 cm) from the rear fascia, the outermost LEDs of the warning display will be ON with increased brightness. As the distance of the detected obstacle to the rear fascia decreases, more LEDs are illuminated. The warning display will not actuate a tone when only yellow LEDs are ON. When the warning display has the first 7 LEDs ON, including 1 red LED, the warning display will actuate an intermittent tone for about 3 sec. The radio will be muted while the tone is actuated. When the detected obstacle is about 11.8 inches (30 cm) from the rear fascia, the warning display will actuate a continuous tone for about 3 sec and it will turn ON all 8 LEDs, including both RED LEDs, on the corresponding side of the display. The radio will be muted while the tone is actuated. When the obstacle is less than 11.8 inches (30 cm) from the rear fascia, the warning display will either have all 8 LEDs ON (obstacle detected) or it will have only the outermost LEDs ON with decreased brightness (obstacle not detected), depending on the location of the obstacle. 3
