from the rear fascia/bumper in the horizontal
direction, depending on the location, type and
orientation of the obstacle.

The Rear ParkSense warning display, located
in the headliner near the liftgate, provides both
audio and visual warnings to indicate the dis-
tance between the rear fascia/bumper and the
detected obstacle.
