Buick 2007 Terraza Owner's Manual page 189

CAUTION:
{
The Ultrasonic Rear Park Assist (URPA)
system does not replace driver vision.
URPA does not:
•
Operate above speeds of
3 mph (5 km/h).
•
Detect objects more than 5 feet
(1.5 meters) behind the vehicle.
This distance may be less during
warmer or humid weather.
•
Detect objects that are below the
bumper, underneath the vehicle, or
that are very close to the vehicle.
•
Detect children, pedestrians,
bicyclists, or pets.
So if you do not use proper care before
backing up, you could hit a vehicle, child,
pedestrian, bicyclist, or pet, resulting in
vehicle damage, injury, or death. Even
though the vehicle has the URPA system,
always check carefully before backing up
by checking behind your vehicle.
While the system is disabled, an indicator light
will be lit on the switch. You will not see any
lights on the rear display if the switch is in the
off position.
URPA can be turned off
by pressing the rear
park aid disable switch
located in the
overhead console
switchbank.
