Limitations of Pilot Assist*
The Pilot Assist function is an aid which can help the driver in many situations. But the driver is at all times responsible for maintaining a safe distance to surrounding objects and a correct position in the lane.
Pilot Assist can switch off or give reduced performance if:
- the lane markings are worn, missing or cross each other.
- lane division is unclear, for example, when the lanes divide or merge or at exits or in the event of multiple sets of markings.
- edges or other lines than lane markings are present on or near the road, e.g. curbs, joints or repairs to the road surface, edges of barriers, roadside edges or strong shadows.
- the lane is narrow or winding.
- weather conditions are poor, e.g. rain, snow or fog or slush or impaired view with poor light conditions, back-lighting, wet road surface etc.
The driver should also note that Pilot Assist has the following limitations:
- High kerbs, roadside barriers, temporary obstacles (traffic cones, safety barriers, etc.) are not detected. Alternatively, they may be detected incorrectly as lane markings, with a subsequent risk of contact between the car and such obstacles. The driver must ensure him/herself that the car is at a suitable distance from such obstacles.
- The camera and radar sensor does not have the capacity to detect all oncoming objects and obstacles in traffic environments, e.g. potholes, stationary obstacles or objects which completely or partially block the route.
- Pilot Assist does not "see" pedestrians, animals etc.
- The recommended steering input is force limited, which means that it cannot always help the driver to steer and keep the car within the lane.
The driver always has the possibility of correcting or adjusting a steering intervention imposed by Pilot Assist and can turn the steering wheel to the desired position.
Steep roads and/or heavy load
Bear in mind that Pilot Assist is primarily intended for use when driving on level road surfaces. The function may have difficulty in keeping the correct distance from the vehicle ahead when driving on steep downhill slopes, with a heavy load or with a trailer - in which case, be extra attentive and ready to brake.
