Is the width of the road too narrow or too wide ? To operate Lane Centering Function and Lane Departure Prevention Function , the width of the road should be between approximately 10 ft ( 3 m ) and 15 ft ( 4.5 m ).
A lead vehicle is driving ahead of my vehicle and the lead vehicle indicator is illuminated , however Lane Centering Function does not activate .
Is the width of the lead vehicle too narrow ? Lane Centering Function does not activate when the lead vehicle is a motorcycle or another 2-wheeled vehicle , super-compact car , or other narrow vehicle .
Is there a speed difference between the lead vehicle and your vehicle ? Or is the lead vehicle not directly in front of your vehicle ? Lane Centering Function may not activate in conditions such as when there is a speed difference between the lead vehicle and your vehicle ( the lead vehicle is pulling away ), or when the lead vehicle is meandering or driving at the edge of the lane .
When Lane Centering Function is active , the interruption screen “ Keep Hands On Steering Wheel ” appears on the combination meter display in spite of gripping the steering wheel .
