Kia Picanto: Radar type autonomous emergency braking / Limitation of the system

Kia Picanto JA 2017-2021 Owner's Manual / Driving your vehicle / Radar type autonomous emergency braking / Limitation of the system

The AEB is an assistant system for a driver in a certain risky driving condition and it does not take every responsibility for all risks from driving condition. The AEB monitors the driving situations through the radar. Thus, for a situation out of the sensing range, the AEB may not normally operate. The driver should pay great caution in the following situations. The AEB operation may be limited.

Recognizing vehicles

- Sensor or sensor cover is contaminated with foreign substances.
- It heavily rains or snows.
- There is interruption by electric waves.
- There is severe irregular reflection from the radar.
- The vehicle in front has a narrow body. (i.e. motor cycle)
- In situations when there is severe radar reflection, the AEB may not operate normally. (parking lot, iron bridge, etc.)
- Special vehicles (bus, truck, constructive vehicle, trailer, etc.) in which radars are difficult to detect, the AEB may not operate normally.
- The vehicle in front is a special vehicle, such as a heavily-loaded truck or a trailer.
- The vehicle driving is unstable.
- The radar sensor recognition is limited.
- Driving on unpaved and uneven road surfaces, or through sudden gradient changes.
- In construction zones or on railroad tracks, or there are metallic objects on the road.
- Driving indoors such as in an underground parking lot.
- Driving in an underground parking lot.
- Entering a tunnel or tollgate.
- There are materials which easily reflect radar signals. (guardrails, approaching vehicles, etc.)

- Driving on a curve

The AEB performance decreases while driving on a curve. The AEB may not recognize the vehicle in front even in the same lane. It may unnecessarily produce the warning message and the warning alarm, or it may not produce the warning message and the warning alarm at all. While driving on a curve, pay great caution, and, if necessary, depress the brake pedal.

While driving on a curve, the AEB may recognize the vehicle in front in the next lane. Pay great caution, and, if necessary, depress the brake pedal. Or, depress the accelerator pedal to maintain the driving speed. Always, take a look around the vehicle for your safety.

- Driving on a slope

The AEB performance decreases while driving upward or downward on a slope, not recognizing the vehicle in front in the same lane. It may unnecessarily produce the warning message and the warning alarm, or it may not produce the warning message and the warning alarm at all. When the AEB suddenly recognizes the vehicle in front while passing over a slope, you may experience sharp deceleration.

Always keep your eyes forward while driving upward or downward on a slope, and, if necessary, depress the brake pedal.

- Changing lanes

Even though the vehicle in the next lane enters into your lane, it may not be recognized by the AEB, until it enters the AEB sensing range.

Especially when the vehicle in the next lane abruptly enters into your lane, it is more likely not be recognized. Always pay great attention.

When the stopped vehicle in front gets out of the lane, it may not be recognized by your AEB. Always pay great attention.

- Recognizing the vehicle

When the vehicle in front has heavy loading extended rearward, or when the vehicle in front has higher ground clearance, it may induce a hazardous situation.
