Hyundai Tucson: Forward/Reverse Parking Distance Warning (PDW) / Parking Distance Warning Malfunction and Limitations

Parking Distance Warning malfunction

After starting the engine, a beep sounds when the gear is shifted to R (Reverse) to indicate Parking Distance Warning is operating normally.

If one or more of the following occurs, check whether the ultrasonic sensor is damaged or blocked.

  • The audible warning does not sound.
  • The buzzer sounds intermittently.
  • The "Parking sensor error or blockage" warning message may appear on the instrument cluster.

If it still does not work properly, have the vehicle inspected by an authorized HYUNDAI dealer.

  • Any sensor is covered or blocked with snow, water, or dirt. Parking Distance Warning operates normally again when unblocked or uncovered.

  • The sensor or sensor assembly is disassembled.

  • Sources that generate ultrasonic waves are near your vehicle.

  • Pedestrians, animals, or objects that are very close to the ultrasonic sensors
