Pilot Assist

Depending on market, this function can be either standard or optional.

Pilot Assist helps the driver keep the vehicle in the current traffic lane by providing steering assistance and maintaining an even speed and a set time interval to the vehicle ahead.

How Pilot Assist works

The Pilot Assist function is primarily intended for use on highways and other major roads where it can help provide a more comfortable and relaxing driving experience.

The camera/radar sensor monitors the distance to the vehicle ahead and detects lane markings.

The driver sets the desired speed and distance to the vehicle ahead. Pilot Assist monitors the distance to the vehicle ahead and the traffic lane's side markers using the camera and radar sensor. The system maintains the set time interval to the vehicle ahead by automatically adjusting your vehicle's speed and keeps your vehicle in its lane by providing steering assistance.

Pilot Assist's steering assistance is based on monitoring the direction of the vehicle ahead and the traffic lane's side marker lines. The driver can override Pilot Assist's steering recommendations at any time and steer in another direction, e.g. to change lanes or avoid obstacles on the road.

If the camera/radar sensor cannot detect the lane's side marker lines or if Pilot Assist is unable for some other reason to clearly interpret the lane, Pilot Assist will temporarily deactivate steering assistance until it can once again interpret the lane markings. However, the speed and distance warnings will remain active.


Pilot Assist is deactivated automatically and resumes working without prior notice.

The color of the steering wheel symbol indicates the current status of steering assistance:

• GREEN indicates that steering assistance is active.

• GRAY (as shown in illustration) indicates that steering assistance is deactivated.


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 function is supplementary driver support intended to facilitate driving and help make it safer – it cannot handle all situations in all traffic, weather and road conditions.
  • The driver is advised to read all sections in the Owner's Manual about this function to learn of its limitations, which the driver must be aware of before using the function.
  • Driver support functions are not a substitute for the driver's attention and judgment. The driver is always responsible for ensuring the vehicle is driven in a safe manner, at the appropriate speed, with an appropriate distance to other vehicles, and in accordance with current traffic rules and regulations.

Pilot Assist regulates speed by accelerating and braking. It is normal for the brakes to emit a slight sound when they are being used to adjust speed.

Pilot Assist attempts to smoothly regulate speed. The driver must apply the brakes in situations requiring immediate braking. For example, when there are great differences in speed between vehicles or if the vehicle ahead brakes suddenly. Due to limitations in the camera and radar sensor, braking may occur unexpectedly or not at all.

Pilot Assist is designed to follow a vehicle ahead in the same lane and maintain a time interval to that vehicle set by the driver. If the radar sensor does not detect a vehicle ahead, it will instead maintain the speed set by the driver. This will also happen if the speed of the vehicle ahead exceeds the set speed for your vehicle.


  • 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.

In curves and forks in the road

Pilot Assist is designed to interact with the driver. The driver should never wait for steering assistance from Pilot Assist, but instead should always be ready to increase his or her own steering efforts, particularly in curves.

  • When the vehicle is approaching an off-ramp or a fork in the road, the driver should steer toward the desired lane to indicate to Pilot Assist the desired direction of travel.

Pilot Assist strives to keep the vehicle in the center of the lane

When Pilot Assist provides steering assistance, it strives to position the vehicle in the center of the lane between the lane markings. For the smoothest driving experience possible, the driver should permit the vehicle to find the optimal positioning. The driver should check that the vehicle is positioned safely in the lane and can always adjust the vehicle's position by applying more force to the steering wheel.

  • If Pilot Assist does not position the vehicle appropriately in the lane, the driver should turn off Pilot Assist or switch to Adaptive Cruise Control.
