When Parking Distance Warning is operating normally, shifting into R (reverse) after starting the vehicle produces a single “beep” as confirmation of normal Parking Distance Warning operation. If any of the below symptoms are observed, check the ultrasonic wave sensors for damage or obstruction. If issues with Parking Distance Warning are experienced, we recommend that your vehicle should be inspected by an authorized HYUNDAI dealer.

  • No confirmation beep

  • Warnings in the problematic direction are displayed on the instrument cluster.

If the cluster warns of limited Parking Distance Warning operation, check for surface cleanliness of the ultrasonic wave sensors. Parking Distance Warning can be impeded if snow, rainwater, or other foreign matter is present on the ultrasonic wave sensor surface. Keep the surface of the ultrasonic wave sensors clean at all times.

When the Parking Distance Warning is operating, if the function is not working normally or the ultrasonic sensor is blocked, the master warning light (X) appears in the direction of the corresponding sensor. You can check the warning in the Utility view on the cluster.

Limitations of Forward/Reverse Parking Distance Warning

  • Parking Distance Warning may not function normally in the following conditions.

    • Frozen snow or rainwater on ultrasonic wave sensor surface (normal functioning resumes once thawed)

    • Snow, rainwater, or other foreign matter on ultrasonic wave sensor surface (normal functioning resumes once removed)

    • Heat waves or extreme cold

    • Dismantling of an ultrasonic wave sensor or an adjacent part

    • Forceful pressing down or impact on ultrasonic wave sensor surface

    • Scratches on ultrasonic wave sensor surface

    • High-pressure water spray (car washes) on ultrasonic wave sensor surface

    • Nearby presence of an ultrasonic wave source, for example, horn of another vehicle, engine sound of a motorcycle, air brake of a large vehicle

  • Parking Distance Warning may malfunction in the following conditions.

    • Heavy rainfall or spray of water

    • Snow over ultrasonic wave sensors

    • Influence of another vehicle’s Parking Distance Warning system

    • Trickling of water on ultrasonic wave sensor surface

    • Operation on uneven/rough roads, gravel roads, hills, or greens

    • Nearby presence of an ultrasonic wave source

    • Positioning of license plate in a non-standard location

    • Bumper height changes and other conditions rendering ultrasonic wave sensor installation different from that at the time of factory release

    • Presence of accessories around ultrasonic wave sensors

  • Warnings of the following objects may not be given.

    • Sharp objects or thin objects (ropes)

    • Narrow objects such as the corners of a square pillar

    • Small objects measuring under 14 cm (5 in.) in diameter or under 100 cm (39 in.) in length

    • Objects that absorb ultrasonic waves, such as cotton, sponges, and snow

    • People, animals, or objects very close to ultrasonic wave sensors

  • Even with Parking Distance Warning, stay attentive while driving and check your front and rear yourself. Surrounding environments and various other conditions can prevent warnings from given.

  • No indemnity is given for accidents or loss occurring from Parking Distance Warning failures.

  • Pay full attention when controlling the vehicle to avoid objects or pedestrians on the road, especially children. As the range and targets of ultrasonic wave sensor operation are limited, warnings may not be given at times.

  • Depending on the speeds of vehicles or the shapes of people, animals, or objects, Parking Distance Warning may not give warnings for all detected targets.

  • If Parking Distance Warning does not function normally, we recommend that your vehicle should be inspected by an authorized HYUNDAI dealer.
