Pilot Assist*1 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 responsible for maintaining a suitable distance to surrounding vehicles or objects 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:
- unclear, worn, or missing lane markings; lane markings that cross over each other; and multiple sets of road markings.
- when the lane divisions change; for example, when lanes divide or merge on highway exits or entrances.
- when there is road construction or there are sudden roadway changes; for example, when lines no longer mark the correct route.
- 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.
Warning
Pilot Assist should only be used if there are clear lane lines painted on each side of the lane. All other use will increase the risk of contact with nearby obstacles that cannot be detected by the functions.
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.
Warning
- This is not a collision avoidance system. The driver is always responsible and must intervene if the system fails to detect a vehicle ahead.
- The function does not brake for people or animals and does not brake for small vehicles, such as bikes and motorcycles. Similarly, it does not brake for low trailers, oncoming, slow-moving or stationary vehicles and objects.
- Do not use the function in demanding situations, such as in city traffic, at intersections, on slippery surfaces, with a lot of water or slush on the road, in heavy rain/snow, in poor visibility, on winding roads, or on on/off ramps.
Note
The function uses the vehicle's camera and/or radar units, which have certain general limitations.
