Ultrasonic Rear Parking Assist (Urpa) - GMC 2007 Yukon XL Owner's Manual

Ultrasonic Rear Parking
Assist (URPA)
If your vehicle has the Ultrasonic Rear Parking
Assist (URPA) system it is designed to help you
park while in Reverse (R). It operates only at
speeds less than 5 mph (8 km/h). URPA helps
make parking easier and helps you avoid colliding
with objects such as parked vehicles. The URPA
system detects objects that are close to the rear of
the vehicle which are at least 10 inches (25.4 cm)
off the ground and below hood or trunk level.
The system detects objects up to 8 feet (2.5 m)
behind your vehicle. URPA determines how close
these objects are from your bumper within this area.
Ultrasonic sensors on the rear bumper are used to
detect the distance to the object.
CAUTION:
{
Even with the Ultrasonic Rear Park Assist
system, the driver must check carefully

operate above speeds of 5 mph (8 km/h).
The system does not detect objects more
than 8 feet (2.5 meters) behind the vehicle.
This detection distance limit may be
reduced during warm weather or high
humidity. Also, the system does not
detect objects that are below your
bumper, underneath your vehicle, or
some objects very close to the vehicle.
The system is not designed to detect
children, pedestrians, bicyclists, or pets.
So, unless you check carefully behind
your vehicle while you are backing up,
they could be injured or killed.
Whether or not you are using rear park
assist, always check carefully behind your
vehicle before backing up and then watch
closely as you do.
