The ultrasonic rear parking assist (URPA) can help a driver
determine how close an object is to the rear bumper within a defined rearward
field of view.
The rear parking assist display is located inside the vehicle above
the rear window. The display has 3 indicators that can be seen through the
rearview mirror or by turning around when seated in the driver
seat.
When the ignition is ON and the vehicle is placed into reverse, the
URPA performs a bulb check. During the bulb check, the 3 indicators on the
display illuminate for approximately 2 seconds to indicate that the system
is working. The URPA performs a bulb check and operates when the following
conditions are present:
| • | The vehicle is placed in REVERSE (R) |
| • | The vehicle speed is less than 5 km/h (3 mph) |
| | At speeds greater than 5 km/h (3 mph), the URPA is disable.
The red indicator flashes to warn the driver that the URPA is disabled. |
The URPA senses how close the vehicle is to an object. The distance
is determined by the four ultrasonic sensors located on the rear bumper.
When the system detects an object, one of the following
will occur:
| • | If the object is less than 0.5 m (20 in) away from the rear of
the vehicle, the amber outside, amber middle, and the red outside indicators
flash and the chime sounds continuosly. |
| • | If the object is 0.5 to 1.0 m (20 to 40 in) away from the rear
of the vehicle, the amber outside, and amber middle indicators flash and
the chime sounds one time on the first detection of an object. |
| • | If the object is 1.0 to 1.5 m (40 in to 5 ft ) away from the rear
of the vehicle, the amber outside indicator flashes and the chime sounds
one time on the first detection of an object. |
The URPA can detect objects 7.6 cm (3 in) wide and at least 25.4 cm
(10 in) tall. It cannot detect objects above the level of the roof.
If the URPA system is not functioning properly, the display flashes
the red indicator after the bulb check, indicating that there is a problem
and the on-board diagnostics need to be entered. Refer to
Diagnostic Trouble Code (DTC) Displaying
