For 1990-2009 cars

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 by the rear window. Refer to Passenger Compartment/Roof Component Views or Luggage Compartment/Rear of Vehicle Component Views for the location of the display. 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:

• | Turn ON the ignition.

• | The vehicle is in REVERSE (R).

• | The vehicle speed is less than 5 km/h (3 mph).

| When the vehicle speed is greater than 5 km/h (3 mph), the URPA is inoperative. The red indicator flashes to warn the driver that the URPA is disabled.

The ultrasonic rear parking assist senses the distance between the vehicle and the 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 0.3 m (11 in) away from the rear of the vehicle, the amber outside, amber middle, and the red outside indicators flash and the chime sounds continuously.

• | If the object is 0.3-0.5 m (11-20 in) away from the rear of the vehicle, the amber outside, amber middle, and the red outside indicators are on and the chime sounds continuously.

• | If the object is 0.5-1.0 m (20-40 in) away from the rear of the vehicle, the amber outside, and the amber middle indicators are on.

• | If the object is 1.0-1.5 m (40 in-5 ft) away from the rear of the vehicle, the amber outside indicator is on and the chime sounds one time on the first detection of an object.

URPA can detect objects of 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 red indicator flashes continuously, the on-board diagnostic needs to be entered to determine if a malfunction is present. Refer to Diagnostic Trouble Code (DTC) Displaying.
