Jeep 2005 Grand Cherokee - Manual (Page 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 bright-
ness. As the distance of the detected obstacle to the rear
fascia decreases, more LEDs are illuminated. The warn-
ing 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.
