The parking sensors will turn off after the vehicle procedes forward at approx. 20 kph. On the console you should have a button maked "P". When you are going to park the vehicle push this button and a light will illuminate showing the sensors are activated. The activated sensors will display on the driver's screen to show distance warnings (green, yellow, red) and chimes will sound accordingly. This button must be pressed to activate this parking assistance feature when you have been driving and are in a parking situation. I hope this has been helpful.
