Hyundai Elantra: Reverse Parking Distance Warning (PDW) / Function malfunction and precautions

Function malfunction

After starting the engine, a beep will sound when the gear is shifted to R (Reverse) to indicate the system is operating normally.

However, if one or more of the following occurs, first check whether the ultrasonic sensor is damaged or whether the system is in a non operating condition. If it still does not work properly, we recommend that the system be inspected by an authorized HYUNDAI dealer.

  • The audible warning does not sound.
  • The buzzer sounds intermittently.
  • The ‘Parking sensor error or blockage’ warning message appears on the cluster.


  • Reverse Parking Distance Warning is a supplemental system. The operation of the system can be affected by several factors (including environmental conditions). It is the responsibility of the driver to always check the rear view before and while parking.
  • Your new vehicle warranty does not cover any accidents or damage to the vehicle.
  • Pay close attention when driving near objects, pedestrians, and especially children. Some objects may not be detected by the ultrasonic sensors, due to the objects distance, size or material, all of which can limit the effectiveness of the sensor.

Limitations of the system

  • Reverse Parking Distance Warning may not operate normally when:
    -- Moisture is frozen to the sensor
    -- Sensor is covered with foreign material, such as snow or water (The system will operate normally when such foreign material are removed.)
    -- The weather is extremely hot or cold
    -- The sensor or sensor assembly is disassembled
    -- The surface of the sensor is pressed hard or an impact is applied with a hard object
    -- The surface of the sensor is scratched with a sharp object
    -- The sensors or its surrounding area is directly sprayed with high pressure washer
  • Reverse Parking Distance Warning may malfunction when:
    -- Heavy rain or water spray is present
    -- Water flows on the surface of the sensor
    -- Affected by another vehicle’s sensors
    -- The sensor is covered with snow
    -- Driving on uneven road, gravel roads or bushes
    -- Objects that generates ultrasonic waves are near the sensor
    -- Installing the license plate differently from the original location
    -- The vehicle bumper height or ultrasonic sensor installation has been modified
  • The following objects may not be detected:
    -- Sharp or slim objects, such as ropes, chains or small poles.
    -- Objects, which tend to absorb sensor frequency, such as clothes, spongy material or snow.
    -- Objects smaller than 40 in. (100 cm) in length and narrower than 6 in. (14 cm) in diameter.
  • Parking Distance Warning Indicators may be displayed differently from the actual detected location when the obstacle is located between the sensors.
  • Parking Distance Warning indicator may not occur sequentially depending on vehicle speed or obstacle shape.
  • If Reverse Parking Distance Warning needs repair, we recommend that the system be inspected by an authorized HYUNDAI dealer.
