When the ignition is turned to the ON position, and the
system is enabled, the warning display will turn ON all
of its LEDs for approximately one second. Then, the
system dimly illuminates the two outer most yellow
LEDs when it is detecting no obstacles. The Rear Park Assist System is active when the ignition is
in the ON position, and the system is enabled, and the
driver shifts the transmission into the “R” (Reverse)
position, and the vehicle speed is less than 11 mph (18
km/h). The following chart shows the warning display
operation when the system is detecting an obstacle:
