Warning Display
The ParkSense ௡ warning display, located in the headliner
near the flipper glass, provides both visible and audible
warnings to indicate the distance between the rear fascia
and the detected obstacle.
When the ignition is turned to the ON position, the
warning display will turn ON all of its LEDs for about
one second. Each side of the warning display has six
yellow and two red LEDs. The vehicle is close to the
obstacle when the red LED is ON.
The system dimly illuminates the two outer most yellow
LEDs when it is ON and detecting no obstacles. The
following chart shows the warning display operation
when the system is detecting an obstacle:
