How The System Works - Chevrolet Silverado 2007 Owner's Manual

The red light in the URPA display will also be lit if
the vehicle is in REVERSE (R). If the vehicle has a
Driver Information Center (DIC), PARK ASSIST
OFF will display on the screen. URPA automatically
turns back on each time the vehicle is started.

How the System Works

When the shift lever is moved into REVERSE (R),
the rear display will briefly come on to let you
know the display is operating correctly. URPA
comes on automatically when the shift lever
is moved into REVERSE (R).
The system 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.
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.
236
If an object is detected at a REVERSE (R) speed
between 0 mph (0 km/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 come on.
•
At distances between 23 inches (0.6 m) and
40 inches (1 m), both amber lights will be on.
•
At distances between 12 inches (0.3 m) and
23 inches (0.6 m), all three lights (amber/
amber/red) will be on.
•
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 flash.
Notice: If you use URPA while the tailgate is
lowered, it may not detect an object behind your
vehicle, and you might back into the object and
damage your vehicle. Always verify the tailgate
is closed when using URPA or turn off URPA
when driving with the tailgate lowered.
URPA cannot detect objects that are above
tailgate level. In order for the rear sensors to
recognize an object, it must be within detection
range behind the vehicle.
