corrective steering intervention to warn you when changing lanes during a potentially critical situation (information
level / warning level). The steering intervention also occurs when you operate the turn signal for the corresponding
direction. If you override the steering intervention, the steering wheel vibrates to give an additional warning. For this,
steering wheel vibration must be activated in the Assist systems menu in the Infotainment system.
Automatic deactivation
The lane change system will switch off automatically if the radar sensors are permanently covered. This can, for
example, be caused by a layer of ice or snow in front of the radar sensor.
A corresponding text notification is shown on the instrument cluster display.
If the lane change system sensor has been automatically deactivated, the system cannot be activated until the
ignition has been switched off and back on again.
The lane change system is switched off automatically when the factory-fitted towing bracket is electrically
connected to a trailer or similar. The lane change system is automatically switched on again when the trailer is
unhitched from the vehicle. The lane change system must be switched off manually for non-factory-fitted towing
brackets.
Brightness
The brightness of the visual display will automatically adapt to the light levels.
Depending on the equipment, you can adjust the basic brightness of the display in the Assist systems menu in the
Infotainment system. The lane change system is not active during the setting procedure.
Troubleshooting
Fault in lane change system.
The indicator lamp lights up yellow. The yellow central warning lamp also lights up.
—Go to a qualified workshop.
No sensor visibility, fault message, system switches itself off.
—Clean radar sensors or remove stickers or accessories from radar sensors (→ Vehicle care, exterior).
—Check for any visible damage.
The system behaves differently than expected.
—The radar sensors are dirty (→ Vehicle care, exterior). The sensor visibility may be impaired by dirt and snow or also
residue from cleaning agents or coatings.
—The general conditions for system operation have not been met(→ Lane change assist system (Side Assist)).
—The radar sensors are covered by water.
—The vehicle is damaged in the area of the radar sensors, e.g. caused by parking collisions.
—The detection ranges of the radar sensors are blocked by add-on parts, e.g. bicycle carriers.
—Changes have been made to the paintwork in the area of the radar sensors or structural modifications have been
made, e.g. on the vehicle front end or the running gear.
—Adhesive tinted films have been added to the side windows after delivery.
