Back-Up Sensors With our Back-Up Sensors, you’ll easily pull in and out of parking spots you may have previously passed over as too small. They also alert you to other vehicles or large obstacles that may be behind you, but out of your line of sight. • Four sensors are mounted on the bumper, for wide area coverage. Obstructions are identified by a beeping sound, which increases as the vehicle moves closer to the obstruction. • On/off switch silences the system when it’s not needed, such as when a trailer is attached.
