FCA Malfunction and Limitations

FCA malfunction

When FCA or related component malfunctions, a warning message, the Master X warning light, and the Forward Safety O or Emergency Steering P warning light appears on the instrument cluster. When the detecting sensors are obscured, the system may be temporarily limited or disabled. The system operates properly when foreign material is removed from the sensors. If the system does not operate properly after it is removed, have your vehicle inspected by an authorized HYUNDAI dealer.

For more information, refer to Driver Assistance System Warnings and Indicators.

Detecting sensors

FCA uses the following sensors:

  • Front view camera

  • Front radar

  • Front corner radar (if equipped)

  • Rear corner radar

For more information, refer to Sensor Information.

FCA limitations

FCA may not operate properly, or it may operate unexpectedly under the following circumstances:

  • Only part of the vehicle, motorcyclist, pedestrian or cyclist is detected

  • The vehicle or motorcyclist in front is a bus, heavy truck, truck with an unusually shaped cargo, trailer, etc.

  • In low light conditions, the tail lamps of the front vehicle or motorcycle are turned off or not bright.

  • The rear of the front vehicle is small or the vehicle does not look normal, such as when the vehicle is tilted, overturned, or the side of the vehicle is visible, etc.

  • The front vehicle's ground clearance is low or high

  • A vehicle, motorcyclist, pedestrian, or cyclist suddenly cuts in front

  • A material is near that reflects very well on the front radar, such as a guardrail, nearby vehicle, etc.

  • The cyclist in front is on a bicycle made of material that does not reflect on the front radar

The illustration above shows the image the front view camera and front radar are capable of detecting as a vehicle, motorcyclist, pedestrian, or cyclist.

Junction Crossing, Lane-Change Oncoming, Lane-Change Side, Evasive Steering Assist function (if equipped)
  • Driving on a highway ramp

  • Driving on a road where the guardrail or wall is in double structure

  • The other vehicle drives very close behind your vehicle, or the other vehicle passes by your vehicle in close proximity

  • The speed of the other vehicle is very fast that it passes by your vehicle in a short time

  • Your vehicle passes by the other vehicle

  • Your vehicle has started at the same time as the vehicle next to you and has accelerated

  • The vehicle in the next lane moves two lanes away from you, or when the vehicle two lanes away moves to the next lane from you

  • The following object is detected:

    • A small motorcycle or bicycle

    • A vehicle such as a flat trailer

    • A big vehicle such as a bus or truck

    • A small moving obstacle such as a pedestrian, animal, shopping cart or a baby stroller

    • A vehicle with low height such as a sports car

  • The lane is difficult to distinguish because:

    • There is a curb or road edges without a lane

    • The lane markings are complicated or a structure substitutes for the lines, such as a construction area

    • The lane is difficult to see due to foreign material, such as rain, snow, dust, sand, oil and water puddles

    • The lane is very wide or narrow

    • There are road markings, such as zigzag lanes, crosswalk markings and road signs

    • There are more than two lane markings on the road

    • The lane number increases or decreases, or the lane markings are crossing

    • The color of the lane marking is not distinguishable from the road due to wet road, etc.

    • There are markings on the road near the lane or the markings on the road looks similar to the lane markings

    • The shadow is on the lane marking by a median strip, trees, guardrail, noise barriers, etc.

    • The lane suddenly disappears, such as at the intersection

    • The distance to the front vehicle is extremely short or the vehicle in front is driving is blocking the lane marking

Limitations of Evasive Steering Assist

Evasive Steering Assist function may not work properly in the following situations when:

  • The pedestrian or cyclist is positioned outside of the operating area.

    2C_EvasiveSteeringAssist_1

  • The pedestrian or cyclist is moving laterally.

    2C_EvasiveSteeringAssist_2

  • The pedestrian or cyclist is positioned inside of the operating area, but there is not enough space available for evasive steering.

    2C_EvasiveSteeringAssist_3

  • Driving on a curved road

    2C_SCCDrivingOnCurve

    FCA may not detect a vehicle, motorcyclist, pedestrian, or cyclist in front of you when driving on curved roads, adversely affecting the performance of the sensors. This may result in no warning, braking assist or steering assist (if equipped) when necessary.

    FCA may detect a vehicle, motorcyclist, pedestrian or cyclist in the next lane or outside the lane when driving on a curved road. If this occurs, FCA may unnecessarily warn the driver, assist emergency braking or emergency steering (if equipped).

    Always check the traffic conditions around the vehicle. If necessary, steer your vehicle and depress the brake pedal to reduce your driving speed.

  • Driving on an inclined road

    2C_FCADrivingOnIncline

    FCA may not detect a vehicle, motorcyclist, pedestrian, or cyclist in front of you while driving uphill or downhill, adversely affecting the performance of the sensors. This may result in no warning, braking assist or steering assist (if equipped) when necessary.

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

    Always have your eyes on the road while driving uphill or downhill and if necessary, steer your vehicle and depress the brake pedal to reduce your driving speed.

  • Changing lanes

    2C_FCAChangingLane

    1. Your vehicle
    2. Lane changing vehicle (into your lane)
    3. Lane changing vehicle (out of your lane)
    4. Same lane vehicle

    When the vehicle (2) moves into your lane from an adjacent lane, it cannot be detected by the sensor until it is in the sensor's detection range. FCA may not immediately detect the vehicle when the vehicle changes lanes abruptly.

    When the vehicle (3) in front of you merges out of the lane, FCA may not immediately detect the vehicle (4) that is now in front of you.

    Always check the traffic conditions around the vehicle. If necessary, steer your vehicle and depress the brake pedal to reduce your driving speed.

  • Detecting vehicle

    2C_CameraRadarDetectingVehicle

    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.

    In this case, you must maintain a safe braking distance, and if necessary, steer your vehicle and depress the brake pedal to reduce your driving speed in order to maintain a safe distance. Always check the traffic conditions around the vehicle.

  • When you are towing a trailer or another vehicle, turn off FCA for safety reasons.

  • FCA may operate if an object that is similar in shape or characteristics to a vehicle, motorcyclist, pedestrian, or cyclist is detected.

  • FCA does not operate on bicycles, or smaller wheeled objects, such as luggage bags, shopping carts, or strollers.

  • FCA may be temporarily disabled if interfered by strong electromagnetic waves.

  • FCA may not operate for about 15 seconds after the vehicle is started or the front view camera is initialized.
