How the System Works
URPA comes on automatically
when the shift lever is moved into
R (Reverse). The rear display briefly
illuminates to indicate the system
is working.
URPA operates only at speeds less
than 5 mph (8 km/h). If the vehicle
is above this speed, the red light on
the rear display flashes.
To be detected, objects must be at
least 10 inches (25.4 cm) off the
ground and below liftgate level.
Objects must also be within 8 feet
(2.5 m) from the rear bumper.
This distance may be less during
warmer or humid weather.
A single beep sounds the first time
an object is detected. Beeping
may occur beginning at 23 inches
(0.6 m). Beeping occurs for a
short time when the vehicle is closer
than 23 inches (0.6 m) and again
at 1 foot (0.3 m) from the object.
The following describes how the URPA display lights appear as the vehicle
gets closer to a detected object:

The system can be disabled through
