Ultrasonic Parking Assist

If available, the Ultrasonic Rear Parking Assist (URPA) system assists the driver with parking and avoiding objects while in R (Reverse). URPA operates at speeds less than 8 km/h (5 mph).

The sensors on the rear bumper are used to detect objects up to 2.5m(8 ft) behind the vehicle, and at least 25 cm (10 in) off the ground.

The URPA system does not detect pedestrians, bicyclists, animals, or any otherWARNING
The URPA system does not detect pedestrians, bicyclists, animals, or any other objects located below the bumper or that are too close or too far from the vehicle. To prevent injury, death, or vehicle damage, even with URPA, always check behind the vehicle and check all mirrors before backing.

How the System Works

URPA comes on automatically when the shift lever is moved into R (Reverse). A single tone sounds to indicate the system is working.

URPA operates only at speeds less than 8 km/h (5 mph).

An obstacle is indicated by audible beeps. The interval between the beeps becomes shorter as the vehicle gets closer to the obstacle.

When the distance is less than 30 cm (12 in) the beeping is a continuous tone for five seconds.

To be detected, objects must be at least 25 cm (10 in) off the ground and below liftgate level. Objects must also be within 2.5 m (8 ft) from the rear bumper. This distance may be less during warmer or humid weather.

Turning the System On and Off

The system can be disabled through the Driver Information Center (DIC).

See “Park Assist” under Vehicle Personalization  for more information.

URPA defaults to the on setting each time the vehicle is started.

When the System Does Not Seem to Work Properly

The following messages may be displayed on the DIC:

SERVICE PARK ASSIST: If this message occurs, take the vehicle to your dealer to repair the system.

PARK ASST BLOCKED SEE OWNERS MANUAL: This message can occur under the following conditions:

► The ultrasonic sensors are not clean. Keep the vehicle's rear bumper free of mud, dirt, snow, ice, and slush. For cleaning instructions, see Exterior Care .

► The park assist sensors are covered by frost or ice. Frost or ice can form around and behind the sensors and may not always be seen; this can occur after washing the vehicle in cold weather. The message may not clear until the frost or ice has melted.

► A trailer was attached to the vehicle, or an object was hanging out of the liftgate during the last drive cycle. Once the object is removed, URPA will return to normal operation.

► A tow bar is attached to the vehicle.

► The bumper is damaged.

Take the vehicle to your dealer to repair the system.

► Other conditions, such as vibrations from a jackhammer or the compression of air brakes on a very large truck, are affecting system performance.
