The ultrasonic parking aid system activates when the ignition switch is turned to the RUN and when the parking brake is OFF. If a front parking aid switch is fitted the system will be de-activated and a light emitting diode (LED) will indicate the state of the system. A lit LED will indicate that the system is currently deactivated. The parking aid system will be disabled if a fault is detected in one of the four front parking aid sensors, the parking aid speaker or the parking aid module. An error tone approximately 3 seconds long will be emitted from the rear parking aid speaker if a fault is detected.
If the rear parking aid speaker is inoperative the error tone will sound from the front parking aid speaker.
