Forward Collision-Avoidance Assist malfunction and limitations

Forward Collision-Avoidance Assist malfunction

2C_DriverAssistanceMalfunction

When Forward Collision-Avoidance Assist is not working properly, the “Check driver assistance system.” warning message appears, and the and warning lights illuminate on the instrument cluster. We recommend that your vehicle be inspected by an authorised HYUNDAI dealer.

Forward Collision-Avoidance Assist disabled

2C_DriverAssistanceLimitedCamera

If the front windscreen where the front view camera is located is covered with foreign material, such as snow or rain, it can reduce the detecting performance and temporarily limit or disable Forward Collision-Avoidance Assist.

If this occurs the “Driver Assistance system limited. Camera obscured.” warning message, and the and warning lights illuminate on the instrument cluster.

Forward Collision-Avoidance Assist operates properly when such snow, rain or foreign material is removed.

If Forward Collision-Avoidance Assist does not operate properly after the obstruction (snow, rain, or foreign material) is removed, we recommend that your vehicle be inspected by an authorised HYUNDAI dealer.

  • Even though the warning message or warning light does not appear on the instrument cluster. Forward Collision-Avoidance Assist may not properly operate.

  • Forward Collision-Avoidance Assist may not properly operate in an area (e.g. open terrain), where any objects are not detected after turning ON the engine.

  • If the vehicle is restarted when the sensors are disabled or malfunctioned, Forward Collision-Avoidance Assist may not operate properly.

  • Unstable driving

  • You are on a roundabout and the vehicle in front is not detected

  • You are continuously driving in a circle

  • The vehicle and motorcycle in front has an unusual shape

  • The vehicle and motorcycle in front is driving uphill or downhill

  • The pedestrian or cyclist is not fully detected, for example, if the pedestrian is leaning over or is not fully walking upright

  • The pedestrian or cyclist is wearing clothing or equipment that makes it difficult to detect as a pedestrian

2C_FrontViewImage_1

The image above shows the image the front view camera will detect as a vehicle and pedestrian.

  • The pedestrian or cyclist in front is moving very quickly

  • The pedestrian or cyclist in front is short or is posing a low posture

  • The pedestrian or cyclist in front has impaired mobility

  • The pedestrian or cyclist in front is moving at right angles to the driving direction

  • There is a group of pedestrians, cyclists or a large crowd in front

  • The pedestrian or cyclist is wearing clothing that easily blends into the background, making it difficult to detect

  • The pedestrian or cyclist is difficult to distinguish from a similar shaped structure in the surroundings

  • You are driving by a pedestrian, cyclist, traffic sign, structure, etc. near a junction

  • Driving in a car park

  • Driving through a tollgate, construction area, unpaved road, partial paved road, uneven road, speed bumps, etc.

  • Driving on a gradient, curved road, etc.

  • Driving on a road with trees or streetlights

  • The adverse road conditions cause excessive vehicle vibrations whilst driving

  • Your vehicle height is low or high due to heavy loads, abnormal tyre pressure, etc.

  • Driving on a narrow road where trees or grass are overgrown

  • There is interference from electromagnetic waves such as driving in an area with strong radio waves or electrical noise

  • Driving on a curved road

    2C_FCADrivingOnCurveRoad_Frontcamera

    2C_FCADrivingOnCurveRoad_Frontcamera_2

    Forward Collision-Avoidance Assist may not detect a vehicle, a motorcycle, a pedestrian or a cyclist in front of you on curved roads adversely affecting the performance of the sensors. This may result in no warning or braking assist when necessary.

    When driving on a curve, you must maintain a safe braking distance, and if necessary, press the brake pedal to reduce your driving speed in order to maintain a safe distance.

    2C_FCADrivingOnCurveRoad_Frontcamera_3

    2C_FCADrivingOnCurveRoad_Frontcamera_4

    Forward Collision-Avoidance Assist may detect a vehicle, motorcycle, pedestrian or cyclist in the next lane or outside the lane when driving on a curved road.

    If this occurs, Forward Collision-Avoidance Assist may unnecessarily warn the driver and control the brake. Always check the traffic conditions around the vehicle.

  • Driving on a gradient

    2C_FCADrivingOnInclinedRoad_3_Frontcamera

    2C_FCADrivingOnInclinedRoad_4_Frontcamera

    Forward Collision-Avoidance Assist may not detect a vehicle, motorcycle, pedestrian or cyclist in front of you whilst driving uphill or downhill adversely affecting the performance of the sensors.

    This may result in unnecessary warning or braking assist, or no warning or braking assist when necessary.

    Also, vehicle speed may rapidly decrease when a vehicle, motorcycle, pedestrian or cyclist ahead is suddenly detected.

    Always have your eyes on the road whilst driving uphill or downhill and if necessary, steer your vehicle and press the brake pedal to reduce your driving speed in order to maintain a safe distance.

  • Changing lanes

    2C_FCAChangingLane

    1. Your vehicle
    2. Lane changing vehicle

    When a vehicle moves into your lane from an adjacent lane, it cannot be detected by the sensor until it is in the sensor’s detection range. Forward Collision-Avoidance Assist may not immediately detect the vehicle when the vehicle changes lanes abruptly. In this case, you must maintain a safe braking distance, and if necessary, press the brake pedal to reduce your driving speed in order to maintain a safe distance.

    2C_FCAChangingLane_2_Frontcamera

    1. Your vehicle
    2. Lane changing vehicle
    3. Same lane vehicle

    When a vehicle in front of you merges out of the lane, Forward Collision-Avoidance Assist may not immediately detect the vehicle that is now in front of you.

    In this case, you must maintain a safe braking distance, and if necessary, press the brake pedal to reduce your driving speed in order to maintain a safe distance.

  • Detecting vehicle

    2C_FCADetectingVehicle_2

    If the vehicle in front of you has cargo that extends rearward from the cab, or when the vehicle in front of you has higher ground clearance, additional special attention is required. Forward Collision-Avoidance Assist may not be able to detect the cargo extending from the vehicle. In these instances, you must maintain a safe braking distance from the rearmost object, and if necessary, press the brake pedal to reduce your driving speed in order to maintain distance.

  • When you are towing a trailer or another vehicle, turn off Forward Collision-Avoidance Assist for safety reasons.

  • Forward Collision-Avoidance Assist may operate if objects that are similar in shape or characteristics to vehicle, motorcycle, pedestrians and cyclists are detected.

  • Forward Collision-Avoidance Assist does not operate for smaller wheeled objects, such as luggage bags, shopping carts, or strollers.

  • Forward Collision-Avoidance Assist may not operate properly with interference from strong electromagnetic waves.

  • Forward Collision-Avoidance Assist may not operate for about 15 seconds after the vehicle is started, or the front view camera is initialised.
