Pilot Assist limitations

Pilot Assist functionality may be limited in certain situations.

Pilot Assist is designed to help the driver in a number of situations. However, the driver always has the primary responsibility for maintaining a safe distance to other vehicles and for keeping the vehicle in its proper traffic lane.

 Warning

Pilot Assist is not a collision avoidance system. The driver is always responsible for steering or applying the brakes if the system does not detect another vehicle.

Do not use Pilot Assist in demanding driving conditions such as city driving or other heavy traffic situations, in slippery conditions, when there is a great deal of water or slush on the road, during heavy rain or snow, in poor visibility, on winding roads or on highway on- or off-ramps.

In certain situations, it may be difficult for Pilot Assist to assist the driver correctly or to deactivate automatically. In such cases, it is advisable not to use Pilot Assist. Examples of such situations may be:
  • the lane's side market lines are missing, badly faded or cross each other.
  • the division of lanes is not clear, e.g., when a line divides or merges with another, at exits or if there are many road signs/markers.
  • there are edges or other lines on or near the lane, e.g., curbs, cracks, repaired areas, sharp shadows, etc.
  • the lane is narrow or winding.
  • the lane is at the top of a hill, on an uneven road surface or over a bump.
  • bad weather conditions (rain, snow, fog, slush, poor visibility, backlighting, etc).
The driver should also be aware that Pilot Assist has the following limitations:
  • High curbs, barriers and temporary obstacles (cones, barriers etc) may not be detected or could be detected incorrectly as side marker lines, which may create a risk of collision. The driver must ensure a safe distance to these obstacles.
  • The camera or radar sensor may not be able to detect objects if there are potholes or if there are stationary objects partially or completely blocking the road.
  • Pilot Assist does not "see" pedestrians, animals, etc.
  • Pilot Assist's steering capacity is limited and may not always be able to help the driver keep the vehicle in the lane.

The driver can always take action to override Pilot Assist.

Steep roads and/or heavy loads

Pilot Assist is primarily intended for use on relatively level 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 attentive and prepared to apply the brakes in these situations.

Do not use Pilot Assist when the vehicle is transporting a heavy load or if it is towing a trailer.

Additional information

  • The Off Road drive mode cannot be selected if Pilot Assist is activated.
  • Pilot Assist uses the vehicle's camera and radar sensor, which have certain general limitations. See the articles "Camera limitations" and "Radar sensor limitations" for additional information.
