Mounted discretely within the lower bumper, the parking distance sensors notify the driver of obstructions behind the vehicle using an alarm sound (beeper). Your customers can now be assisted in determining distance when parallel parking, backing their vehicle into a garage and backing out of parking areas. There is also an available on/off switch for use when towing. When you select a genuine OEM part - you can rely on the high quality and effectiveness of the product and brand without having to guess if the product will work in sequence with your vehicle. Protecting your investment is important and choosing the right parts can be challenging. Stick with what you know and choose a genuine OEM part. Fits: 2013 Mazda CX-5.
