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 shifting into REVERSE (R) and an
object is detected, one of the following will occur:

2-119
A chime will sound the first time an object is detected.
URPA can detect objects 3 inches (7.6 cm) and wider,
and at least 10 inches (25.4 cm) tall, but it cannot detect
objects that are above trunk level. In order for the rear
sensors to recognize an object, it must be within
operating range.
If the URPA system is not functioning properly, the
display will flash red, indicating that there is a problem.
The light will also flash red while driving if a trailer is
attached to your vehicle, or a bicycle or object is on the
back of, or hanging out of your trunk. The light will
continue to flash until the trailer or the object is
removed and your vehicle is driven forward at least
15 mph (25 km/h). It may also flash red if the ultrasonic
sensors are not kept clean. So be sure to keep your rear
bumper free of mud, dirt, snow, ice and slush or the
system may not work properly. If after cleaning the rear bumper and driving forward at
least 15 mph (25 km/h), the display continues to flash
red, see your dealer. It may also flash red if your vehicle
is moving in REVERSE (R) at a speed greater than
3 mph (5 km/h). Other conditions that may affect
system performance include things like the vibrations
from a jackhammer or the compression of air brakes
on a very large truck.
As always, drivers should use care when backing up a
vehicle. Always look behind you, being sure to check
for other vehicles, obstructions and blind spots. For
cleaning instructions, see ªCleaning Your Vehicleº in
the Index.
