Ultrasonic Rear Parking Assist
(URPA) (Option)
Ultrasonic Rear Parking Assist can help you to
determine how close an object is to your rear bumper
within a given area, making parking easier.
The URPA display is
located inside the vehicle,
above the rear window. It
has three color
-
coded lights
that can be seen through the
rearview mirror or by
turning around.
How the System Works
URPA comes on automatically when the shift lever is
moved into REVERSE (R) and the vehicle speed is less
than 3 mph (5 km/h). When the system comes on, the
three lights on the display will illuminate to let you
know that the system is working. URPA senses how
close your vehicle is to an object. The distance is
determined by the four ultrasonic sensors located on the
rear bumper. When you shift into REVERSE (R) and an
object is detected, the following will occur in sequence
depending on the distance from the object:
D At 5 feet (1.5 m) a chime will sound and one amber
light will be lit;
D at 40 inches (1.0 m) both amber lights will be lit;
D at 20 inches (0.5 m) a continuous chime will sound
and all three lights (amber/amber/red) will be lit; and
D at 1 foot (0.3 m) a continuous chime will sound and
all three lights (amber/amber/red) will flash.
