In general, if objects are detected at the same time near both the front and rear bumpers while backing up, the beeps only sound to indicate that objects are close to the rear bumper.

However, if an object comes within 0.3m (1 ft) of the front bumper while the vehicle is backing up and at the same time there is another object further than 0.3m (1 ft) from the rear bumper, then the beeps only sound to indicate the object that is closer to the front bumper.
