Reversing sensor system warning display
In case there is a malfunction in the reversing sensor system, the display for the malfunctioning sensor will blink and the warning buzzer will sound for approximately 5 seconds. Even after the buzzer has stopped sounding, the display will continue blinking until the system reverts to the normal state. Have the vehicle inspected at a MITSUBISHI MOTORS Authorized Service Point.
