How The System Works - Buick 2006 Lucerne Owner's Manual

CAUTION:
{
Even with the Ultrasonic Rear Park Assist
system, the driver must check carefully before
backing up. The system does not 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. 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.
The display has three color-coded lights. The URPA
lights are used to provide distance and system
information, along with beeps played out the speakers.

How the System Works

When the shift lever is moved into REVERSE (R),
the rear display will briefly illuminate to let you know
the display is operating correctly. URPA comes on
automatically when the shift lever is moved into
REVERSE (R). The system also does not work at a
reverse speed greater than 5 mph (8 km/h). To remind
you of this, the red light on the rear display will flash.
The system can be disabled using the Driver Information
Center (DIC). See DIC Controls and Displays on
page 3-50.
The display is located near
the rear window and can
be seen by looking
over your right shoulder.
