Hyundai Palisade: Forward Collision-Avoidance Assist (FCA) system / System Malfunction

Hyundai Palisade (LX2) 2020-2024 Owner's Manual / Driving Your Vehicle / Forward Collision-Avoidance Assist (FCA) system / System Malfunction

Hyundai Palisade. System Malfunction

Check Forward Collision- Avoidance Assist system

When FCA is not working properly, the FCA warning light () will illuminate and the warning message will appear for a few seconds. After the message disappears, the master warning light () will illuminate. In this case, have the vehicle inspected by an authorized HYUNDAI dealer.
The FCA warning message may appear along with the illumination of the ESC (Electronic Stability Control) warning light.

Both FCA warning light and warning message will disappear once the ESC warning light issue is resolved.

WARNING

FCA is only a supplemental system for the driver's convenience. It is the driver's responsibility to control the vehicle operation. Do not solely depend on the FCA system. Rather, maintain a safe braking distance, and, if necessary, depress the brake pedal to reduce the driving speed or to stop the vehicle.
In certain instances and under certain driving conditions, the FCA system may activate prematurely. This initial warning message appears on the LCD display with a warning chime. Also due to sensing limitations, in certain situations, the front radar sensor or camera recognition system may not detect the vehicle, pedestrian ahead. The FCA system may not activate and the warning message may not be displayed.
If there is a malfunction with the FCA system, the Forward Collision avoidance assist system is not applied even though the braking system is operating normally.
If the vehicle in front stops suddenly, you may have less control of the brake system. Therefore, always keep a safe distance between your vehicle and the vehicle in front of you.
The FCA system may activate during braking and the vehicle may stop suddenly shifting loose objects toward the passengers. Always keep loose objects secured.
The FCA system may not activate if the driver applies the brake pedal to avoid collision.
The brake control may be insufficient, possibly causing a collision, if a vehicle in front abruptly stops. Always pay extreme caution.
The FCA system may not activate according to the road conditions, inclement weather, driving conditions or traffic conditions.
Occupants may get injured, if the vehicle abruptly stops by the activated FCA system. Pay extreme caution.
The FCA system operates only to detect vehicles, pedestrian in front of the vehicle.

WARNING

The FCA system operates only to help detect vehicles or pedestrians in front of the vehicle.
The FCA system does not operate when the vehicle is in reverse.
The FCA system is not designed to detect other objects on the road such as animals.
The FCA system does not detect vehicles in the opposite lane.
The FCA system does not detect cross traffic vehicles that are approaching.
The FCA system cannot detect the cross traffic cyclist that are approaching.
The FCA system cannot detect vehicles that are stopped vertically to your vehicle at a intersection or dead end street.

In these cases, you must maintain a safe braking distance, and if necessary, depress the brake pedal to reduce the driving speed in order to maintain a safe distance or to stop the vehicle.

FCA Sensor (Front Radar/Front Camera)

■ Front radar ■ Front camera In order for the FCA system to operate properly, always make sure the sensor cover or sensor is clean and free of dirt, snow, and debris...

Limitations of the System

The Forward Collision Avoidance Assist (FCA) system is designed to monitor the vehicle ahead or a pedestrian on the roadway through radar signals and camera recognition to warn the driver that a collision is imminent, and if necessary, apply emergency braking...
