When the System Does Not Seem to Work Properly

The following messages may be displayed on the DIC:

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

PARKING ASSIST OFF: This message occurs if the driver disables the system or if the vehicle is driven above 8 km/h (5 mph) in R (Reverse).

PARKING ASSIST 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, slush, and frost. The message may not clear until frost or ice has melted all around and inside the sensor.
  • A trailer is attached to the vehicle, or a bicycle or an object was hanging out of the liftgate during the current or last drive cycle. URPA will return to normal operation after it is determined the object is removed. This could take a few drive cycles.
  • A tow bar is attached to the vehicle.

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