Active Lane Change Assist supports the driver when changing lanes by applying steering torque if the driver operates a turn signal indicator.
Observe the notes on driving systems and your responsibility; you may otherwise fail to recognise dangers More.
You are driving on a motorway or road with multiple lanes in the direction of travel.
The neighbouring lane is separated by a broken lane marking.
No vehicle is detected in the adjacent lane.
Active Lane Change Assist is switched on in the multimedia system.
Active Steering Assist is activated and active.
If no vehicle is detected in the adjacent lane and a lane change is permitted, the lane change begins after the driver has activated the turn signal indicator. This is shown to the driver with a green arrow next to the steering wheel symbol. The Lane change to the leftmessage, for example, also appears. If Active Lane Change Assist has been activated with the turn signal indicator but a lane change is not immediately possible, a grey arrow appears next to the steering wheel symbol, which remains green.
When the lane change assistance starts, the turn signal indicator is automatically activated along with the display in the multifunction display.
If the assistance graphic is shown when changing lanes, the lane change display appears with an additional arrow pointing towards the adjacent lane More
If a lane change is not possible, the arrow is faded out after a few seconds and a new lane change must be initiated. An immediate lane change is only possible on motorway sections without speed limits.
If the system is impaired, Active Lane Change Assist may be cancelled. The Lane change cancelled message appears in the multifunction display.
In addition, a warning tone may sound.
Lane Change Assist cannot always clearly detect if the adjacent lane is free.
The lane change might be initiated although the adjacent lane is not free.
If the system limitations for Lane Change Assist have been reached, there is no guarantee that the system will remain active.
Lane Change Assist cannot then assist you by applying steering torques.
The system limitations of Active Steering Assist apply to Active Lane Change Assist More.
The sensors in the rear bumper are dirty, damaged or covered by a sticker or ice and snow, for example.
The exterior lighting shows a defect.
The Active Lane Change Assist sensors adjust automatically while a certain distance is being driven after the vehicle has been delivered. Active Lane Change Assist is unavailable or only partially available during this teach-in process; no arrow appears next to the Active Steering Assist symbol when the turn signal indicator is activated.
