System Limitations

The Autonomous Emergency Braking (AEB) system is designed to monitor the vehicle or pedestrian ahead on the road through radar signals and camera recognition, warn the driver of an unavoidable collision, and apply emergency braking if necessary.

In certain situations, the radar sensor or camera may not detect a vehicle or pedestrian ahead. In these cases, the AEB system may not operate normally. The driver must be especially attentive in the following situations, where AEB operation may be limited.

Vehicle Detection

The sensor may be limited when:

- The radar sensor or camera is blocked by a foreign object or debris
- Adverse weather conditions, such as heavy rain or snow, obstruct the field of view of the radar sensor or camera
- Electromagnetic wave interference is present
- Strong uneven reflection from the radar sensor is present
- The vehicle ahead is too small to be detected by the camera recognition system (for example, a motorcycle or bicycle, etc.)
- The vehicle ahead is a large vehicle or trailer that is too large to be detected by the camera recognition system (for example, a tractor trailer, etc.)
- The driver's field of view is poorly lit (either too dark or too bright due to reflections, or excessive backlight that obstructs the field of view)
- The tail lights of the vehicle ahead are not illuminated properly
- External brightness changes abruptly, such as when entering or exiting a tunnel
- The vehicle ahead moves erratically

- Driving on curves

AEB system operation may be limited when driving on a curved road.

In some cases, the AEB system may activate prematurely on a curved road.

In addition, in some cases the front radar sensor or camera recognition system may not detect a vehicle traveling on a winding road.

In these cases, the driver must maintain a safe braking distance and, if necessary, depress the brake pedal to reduce vehicle speed and maintain a safe distance.

- Driving on slopes

AEB performance is reduced when driving uphill or downhill, and it may not recognize a vehicle ahead in the same lane. It may issue an unnecessary warning message and warning signal, or it may not issue a warning message and warning signal at all.

When the AEB system suddenly recognizes a vehicle ahead while driving on a slope, you may experience sudden deceleration.

Always look ahead when driving uphill or downhill and, if necessary, depress the brake pedal to reduce vehicle speed and maintain distance.

- Lane change

When a vehicle changes lanes in front of you, the AEB system may not detect the vehicle immediately, especially if it changes lanes abruptly. In this case, maintain a safe braking distance and, if necessary, depress the brake pedal to reduce speed and maintain a safe distance.

When driving in stop-and-go traffic and a vehicle that was outside your lane stops in front of you, the AEB system may not detect the new vehicle immediately. In this case, maintain a safe braking distance and, if necessary, depress the brake pedal to reduce speed and maintain a safe distance.

- Detection of the vehicle ahead

If the vehicle ahead has cargo extending rearward from the vehicle body, or if a vehicle with high ground clearance is ahead of you, special attention is required. The AEB system may not detect cargo extending from the vehicle. In such cases, maintain a safe braking distance from the rearmost object and, if necessary, depress the brake pedal to reduce speed and maintain a safe distance.

Pedestrian Detection

The sensor may be limited when:

- The pedestrian is not fully recognized by the camera recognition system, for example, if the pedestrian is leaning or is not standing fully upright
- The pedestrian moves very quickly or suddenly appears in the camera's field of view
- The pedestrian wears clothing that blends easily into the background, making detection by the camera recognition system difficult
- External lighting is too bright (for example, driving in bright sunlight or sun glare) or too dark (for example, driving on a dark rural road at night)
- It is difficult to detect and distinguish a pedestrian from other objects in the surroundings, for example, when there is a group of pedestrians or a large crowd

WARNING

• Do not use the Autonomous Emergency Braking system when towing a vehicle. Operating the AEB system while towing may adversely affect the safety of your vehicle or tow vehicle.
• Exercise extreme caution if the vehicle ahead has a load extending rearward from the cab, or when the vehicle ahead has a high ground clearance.
• The AEB system is designed to detect and track a vehicle ahead or a pedestrian in the roadway using radar and camera recognition signals. It is not designed to detect bicycles, motorcycles, or small wheeled objects, such as luggage bags, shopping carts, or baby strollers.
• Never attempt to test the operation of the AEB system. This may result in serious injury or death.

Information

In some cases, the AEB system may be disabled due to electromagnetic interference.
