Ultrasonic Rear Parking
Assist (URPA)
Your vehicle may be equipped with Ultrasonic Rear
Parking Assist (URPA). URPA is designed to help you
park while in REVERSE (R) and operates only at speeds
less than 3 mph (5 km/h). URPA can help you avoid
colliding with objects such as parked vehicles. The
system can detect objects 5 feet (1.5 m) behind your
vehicle and tell you how close those objects are to your
rear bumper.

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.
{CAUTION:
Even with the Ultrasonic Rear Park Assist
system, the driver must check carefully
before backing up. The system does not
operate above typical backing speeds of
3 mph (5 km/h) while parking. And, the system
does not detect objects that are more than
5 feet (1.5 meters) behind the vehicle.
So, unless you check carefully behind you
before and when you back up, you could strike
children, pedestrians, bicyclists or pets behind
you, and they could be injured or killed.
Whether or not you are using rear park assist,
always check carefully behind your vehicle
before you back up and then watch closely as
you do.
How the System Works
URPA comes on automatically when the shift lever is
moved into REVERSE (R). When the system comes on,
the three lights on the display will brie y illuminate to
let you know that the system is working. If your vehicle is
moving in REVERSE (R) at a speed greater than
3 mph (5 km/h), the red light will ash to remind you the
system does not work at this speed.
The rst time an object is detected while in
REVERSE (R), a chime will sound and the following will
occur in sequence, depending on the distance from
the object:
At 5 feet (1.5 m) a chime will sound and one amber
light will be lit.
At 40 inches (1.0 m) both amber lights will be lit.
At 20 inches (0.5 m) a continuous chime will sound
and all three lights (amber/amber/red) will be lit.
At 1 foot (0.3 m) a continuous chime will sound and
all three lights (amber/amber/red) will ash.
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.
