REAR PARK ASSIST SYSTEM — IF EQUIPPED
This system is used to help drivers determine if an
obstacle is in the way of the vehicle while it is backing up
in addition to the use of inside rearview and outside
mirrors.
When the driver selects Reverse the system scans for
objects behind the vehicle using four sensors located in
the rear bumper. Objects can be detected from up to 71
inches (180 cm). A warning display above the rear
window provides both visible and audible warnings
indicating the range of the object.
