This is showntothe driver with a greenarrow2nexttothesteering wheel symbol.TheLane Change to the Leftmessage alsoappears,forexample. IfActive Lane ChangeAssisthas been activated withthe turn signalindicator but a lanechange is not immediatelypossible, a grayarrow1appears nexttothesteering wheel symbol, whichremains green.
Whenthe lanechange assistancestarts,the turnsignal indicator is automatically activated besidethe display inthe multifunction display.
Ifthe assistance graphic is shown whenchang‐ing lanes,the lanechange display appears with
an additional arrowpointingtowardsthe adja‐cent lane (page193).
If a lanechange is not possible,the arrow fadesout after afew seconds and a new lanechangemust be initiated. An immediate lanechange isonly possible on freeway sections without speedlimits.
