Buick Lucerne 2007, Owner'S Manual

Page: 179 / 496

The display is located
near the rear window
and can be seen
by looking over your
right shoulder.
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 212 .
How the System Works when Backing
If the shift lever is in REVERSE (R), URPA detects
objects close to the rear bumper. The first time an
object is detected a single beep will sound. If an
object is detected at a REVERSE (R) speed
between 0 mph (0km/h) and 5 mph (8 km/h), the
following describes what will occur based on your
distance to a detected object located behind the
vehicle:
•
At distances between 40 inches (1 m) and
8 ft (2.5 m), a single amber light will be lit.
•
At distances between 23 inches (0.6 m) and
40 inches (1 m), both amber lights will be lit.
•
At distances between 12 inches (0.3 m)
and 23 inches (0.6 m), all three lights
(amber/amber/red) will be lit.
•
At distances less than 12 inches (0.3 m), a
beeping sound will repeat for a short time and
all three lights (amber/amber/red) will be lit and
flashing.
