Pilot Assist limitations

Pilot Assist functionality may be reduced in certain situations.

Pilot Assist is a driver support function designed to simplify driving and assist the driver in many situations. However, the driver is always responsible for maintaining a suitable distance to vehicles or objects around it and ensuring that the vehicle is correctly positioned in the traffic lane.

Warning

In some situations, Pilot Assist may have trouble helping the driver properly or may be deactivated automatically – we advise against using Pilot Assist in such cases. Examples of such situations include:

  • 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 when there are 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.
  • the lane contains ridges or holes.
  • weather conditions are poor, e.g. rain, snow or fog or slush or reduced visibility with poor light conditions, backlighting, wet road surface, etc.

The driver should also note that Pilot Assist has the following limitations:

  • High curbs, 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 vehicle and such obstacles. The driver is responsible for ensuring that the vehicle maintains a suitable distance from such obstacles.
  • The camera and radar sensors do not have the capacity to detect all oncoming objects and obstacles in traffic environments, e.g. potholes, stationary obstacles or objects that completely or partially block the route.
  • Pilot Assist does not "see" pedestrians, animals, etc.
  • The recommended steering input is limited in force, which means that it cannot always help the driver to steer and keep the vehicle within the lane.
  • In vehicles equipped with Sensus Navigation*, the function is able to use information from map data, which could cause variations in performance.
  • Pilot Assist will be switched off if the speed-dependent power steering wheel resistance is working at reduced power, e.g. during cooling due to overheating.

The driver can always correct or adjust steering assistance provided by Pilot Assist by turning the steering wheel to the desired position.

Steep roads and/or heavy loads

Pilot Assist is primarily intended to be driven on flat roads. The function may not be able to maintain the correct time interval to the vehicle ahead when driving down steep hills. The driver should be extra attentive and prepared to apply the brakes.

  • Do not use Pilot Assist if the vehicle is carrying a heavy load or towing a trailer.

Note

Pilot Assist cannot be activated if a trailer, bike carrier or similar is connected to the vehicle electrical system.

Other limitations

  • The Off Road drive mode cannot be selected when Pilot Assist is activated.

Note

The function uses the vehicle's camera and radar sensor, which has certain general limitations.
