Object Detection Systems

Ultrasonic Rear Parking
Assist (URPA)
For vehicles with the Ultrasonic Rear Parking
Assist (URPA) system, it operates at speeds less than
8 km/h (5 mph), and assists the driver with parking and
avoiding objects while in R (Reverse). The sensors on
the rear bumper are used to detect the distance to an
object up to 2.5 m (8 ft) behind the vehicle, and at least
25.4 cm (10 in) off the ground.
WARNING:
The Ultrasonic Rear Parking Assist (URPA)
system does not replace driver vision. It cannot
detect:
Objects that are below the bumper,
underneath the vehicle, or if they are too
close or far from the vehicle
Children, pedestrians, bicyclists, or pets.
