Display and warning

The availability and readiness to provide warnings will be indicated with the indicator lights. You can also open the Driver assistance display in the on-board computer. The displays correspond to the functions of the indicator lights.

  1. White lines: the lane departure warning is switched on but not ready to provide warnings.
  2. Green line: the lane departure warning is ready to provide warnings on the respective side.
  3. Corrective steering will be indicated with .

    If the lane departure warning must intervene for along period of time, a message will request the driver to drive in the center of the lane. The steering wheel can also vibrate to warn you if lane boundaries are detected during a passing maneuver.

The lane departure warning is ready to provide warnings if an object is detected on at least one side of the individual lane.

If the indicator light turns on, the lane departure warning is not ready to provide warnings.

This may occur due to the following system limits or situations:

  • The necessary lane marker lines have not been detected (for example, in a construction zone or because the lines are obstructed by snow, dirt, water, or lighting)
  • The speed is below the activation speed
  • The lane is too narrow or too wide
  • The curve is too narrow
  • Visibility is obstructed by a rise or dip.
  • The driver's hands are not on the steering wheel
  • The turn signal was activated.

Steering intervention request

If the lane departure warning intervenes multiple times when no steering activity is detected, the steering intervention request will provide a warning using audio and visual signals, such as .

Take over the steering and keep your hands on the steering wheel so that you will be ready to steer at any time. The system may no longer be ready to provide warnings after a short time, and it will only become active again later.

If the driver does not take over steering, the lane departure warning will no longer be ready to provide warnings. If the vehicle is equipped with emergency assist and it is ready to function, it will be activated.

Behavior when a turn signal is active

Applies to: vehicles with side assist: The system will not warn you if you activate a turn signal before crossing the lane marker line. In this case, it assumes that you are changing lanes intentionally.

Applies to: vehicles with side assist: If the turn signal is activated, the lane departure warning is ready, and a lane change has been classified as critical by the lane departure warning due to vehicles traveling beside you or due to approaching vehicles, then a noticeable corrective steering movement will occur shortly before exiting the lane. This will attempt to keep your vehicle in the lane.

WARNING

  • Observe the safety precautions and note the limits of the assist systems, sensors, and cameras.
  • The system warns the driver that the vehicle is leaving the lane using corrective steering.

    The driver is always responsible for keeping the vehicle within the lane.

  • Corrective steering may not occur at all in certain situations, such as during heavy braking. Always be ready to intervene.

Tips

  • Always keep your hands on the steering wheel so you can be ready to steer at any time. The driver is always responsible for adhering to the regulations applicable in the country where the vehicle is being operated.
  • The system does not provide any corrective steering or steering wheel vibrations if it detects that you are passing another vehicle
