Ultrasonic rear parking assist (URPA) can help a driver
determine how close an object is to the rear bumper within a given area, making
parking easier.
The information center telltale assembly 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.
URPA comes on automatically when the shift lever is moved into REVERSE
(R) and the vehicle speed is less than 5 km/h (3 mph). When the system comes
on, the three lights on the display 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:
| • | Less than 12 in (0.3 m) -- Amber/Amber/Red lights flashing
and continuous chime. |
| • | 12 to 20 in (0.3 to 0.5 m) -- Amber/Amber/Red lights on and
continuous chime |
| • | 20 to 40 in (0.5 to 1.0 m) -- Amber/Amber Lights On |
| • | 40 in to 5 ft (1.0 to 1.5 M) -- Amber Light |
URPA can detect objects 3 in (7.6 cm) and wider, and at least 10 inches
(25.4 cm) tall, but it can not detect objects above the level of the rear
compartment. 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 flashes
red, indicating that there is a problem.
Rear Object Sensor Control Module Connector
The rear object sensor control module connector (harness side) has a
retainer (1) and cover (2) as well as a secondary lock (5). The secondary
lock must be removed from the connector body (3) before removing or installing
connector terminals.
