Hyundai Azera: Rear parking assist system (If equipped)

The rear parking assist system assists the driver during reverse movement of the vehicle by chiming if any object is sensed within a distance of 47 in. (120 cm) behind the vehicle. This system is a supplemental system and it is not intended to nor does it replace the need for extreme care and attention of the driver. The sensing range and objects detectable by the back sensors are limited. Whenever backingup, pay as much attention to what is behind you as you would in a vehicle without a rear parking assist system.
WARNING - Rear parking
The rear parking assist system is a supplementary function only. The operation of the rear parking assist system can be affected by several factors (including environmental conditions). To avoid collision with children, pedistrians, objects, or vehicles, it is the responsibility of the driver to always check the area behind the vehicle before and while backing up. Otherwise serious injuries could occur.
