Buick 2007 Rendezvous Owner's Manual page 197

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.
When the system is disabled, an indicator light will
glow on the switch. You will not see any lights on
the rear display if the switch is in the off position.
How the System Works
Unless disabled, the URPA will turn on
automatically when the shift lever is moved into
REVERSE (R). When the system turns on, the
three lights on the display will illuminate for one and
a half seconds to let you know that the system is
working. If your vehicle is moving in REVERSE (R)
at a speed greater than 3 mph (5 km/h), the red
light will flash to remind you that the system does
not work at speed greater than 3 mph (5 km/h).
URPA can be turned off
by pressing the rear
park aid disable switch
located in the
instrument panel
switchbank.
