If your vehicle is equipped with the Ultrasonic Rear Parking Assist (URPA) system, it is designed to help you park, while the vehicle is in REVERSE (R). It operates only at very low speeds, less than 3 mph (5 km/h). URPA can help make parking easier and to help you avoid colliding with objects such as parked vehicles. The URPA system can detect objects up to 5 feet (1.5 m) behind the vehicle, and tell you how close these objects are from your rear bumper.
Your vehicle's URPA operates when the shift lever is moved into REVERSE (R) and the vehicle speed is less than 3 mph (5 km/h). Four ultrasonic sensors located at the rear bumper are used to detect the distance to the object. The URPA display is located inside the vehicle, near the rear window. It has three color-coded lights used to provide distance and system information to the driver.
Caution: The Ultrasonic Rear Park Assist (URPA) system does not replace driver vision. URPA
does not:
• Operate above speeds of 3 mph (5 km/h). • Detect objects more than 5 feet (1.5 meters) behind the vehicle. This
distance may be less during warmer or humid weather. • Detect objects that are below the bumper, underneath the vehicle, or that
are very close to the vehicle. • Detect children, pedestrians, bicyclists, or pets.
URPA can be turned off by pressing the rear park aid disable switch located in the overhead console switchbank.
While the system is disabled, an indicator light will be lit on the switch. You will not see any lights on the rear display if the switch is in the off position.
How the System Works
Unless disabled, the URPA will turn on automatically when the shift lever is moved into REVERSE (R). When the system turns on, the three lights on the display will illuminate for one and a half seconds 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 flash to remind you that the system does not work at speed greater than 3 mph (5 km/h).
If an object is detected at a REVERSE (R) speed of less than 3 mph (5 km/h), one of the following will occur:
Description | English | Metric |
|---|---|---|
amber light | 5 ft | 1.5 m |
amber/amber lights | 40 in | 1.0 m |
amber/amber/red lights & continuous chime | 20 in | 0.5 m |
amber/amber/red lights flashing & continuous chime | 1 ft | 0.3 m |
A chime will sound the first time an object is detected between 20 inches (0.5 m) and 5 feet (1.5 m) away.
URPA cannot detect objects that are above liftgate level. In order for the rear sensors to recognize an object, it must be within detection range behind the vehicle.
When the System Does Not Seem to Work Properly
The light may flash red when the vehicle is in REVERSE (R) if the ultrasonic sensors are not kept clean. So be sure to keep your rear bumper free of mud, dirt, snow, ice and slush. 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. If after cleaning the rear bumper and then driving forward at least 15 mph (25 km/h), the display continues to flash red, see your dealer/retailer.
If a trailer was attached to your vehicle, or a bicycle or an object was on the back of, or hanging out of your liftgate during your last drive cycle, the light may also flash red. The light will continue to flash whenever in REVERSE (R) until your vehicle is driven forward at least 15 mph (25 km/h) without any obstructions behind the vehicle.
