Limitations of Lane Keeping Assist

Lane Keeping Assist may not operate properly or may operate unexpectedly in certain circumstances, including the following

  • The lane is contaminated or difficult to detect because:

    • The lane markings (or road edges) are covered with rain, snow, dirt, oil, and so on.

    • The colour of the lane marking (or road edge) is not distinguishable from the road.

    • There are markings (or road edges) near the lane, or the markings (or road edges) look similar to lane markings.

    • The lane marking (or road edge) is indistinct or damaged.

    • When the shadow of objects around the road (median conditions, crash barriers, noise barrier,s surrounding bushes, etc.) or the shadow of a vehicle covers the lane.

    • When a long object is lying on the road.

    • When there are longitudinal cracks on the road surface.

  • The lane number increases or decreases, or the lane markings (or road edges) cross.

  • There are more than two lane markings (or road edges).

  • The lane markings (or road edges) are complicated or a structure substitutes for the lines, such as a construction area

  • There are road markings such as crosswalk markings or road signs.

  • The lane suddenly disappears, such as at an intersection.

  • The lane or road is very wide or narrow.

  • There is a road edge without a lane.

  • Driving on a sharply curved road.

  • There is a boundary structure in the roadway, such as a tollgate, sidewalk, kerb, and so on.

  • You are driving extremely close to the vehicle ahead, or it is covering the lane marking (or road edge).

  • Driving in a bus-only lane or in the lanes immediately to the left or right of a bus-only lane.

WARNING

  • You are responsible for driving safely and controlling the vehicle. Do not rely on Lane Keeping Assist and drive dangerously.

  • Lane Keeping Assist may stop operating or may not work properly depending on road conditions and surroundings. Always be cautious whilst driving.

  • When you are towing a trailer or another vehicle, turn OFF Lane Keeping Assist for safety reasons.

  • If the vehicle is driven at high speed, the steering wheel will not be controlled. The driver must always follow the speed limit.

  • Lane Keeping Assist may not display a warning message or generate an audible warning if any other function’s warning message is displayed or audible warning is generated.

  • You may not hear the warning sound of Lane Keeping Assist if the surroundings are noisy. Moderately adjust the vehicle volume and always pay attention to the surroundings.

  • If you attach objects to the steering wheel, steering may not be assisted properly.

  • Lane Keeping Assist may not operate for approximately 15 seconds after the vehicle is started or the front view camera is initialized.

  • Lane Keeping Assist will not operate when:

    • The turn signal is activated or within a certain period after it is turned off.

    • The vehicle is not driven in the centre of the lane when Lane Keeping Assist is turned on or right after changing a lane.

    • ESC (Electronic Stability Control) or VSM (Vehicle Stability Management) is activated.

    • The vehicle turns quickly on a curved road.

    • The vehicle changes lanes suddenly.

    • The vehicle brakes suddenly.

  • Loading freight exceeding the maximum load or placing freight unevenly may impede safe driving. This may also prevent Lane Keeping Assist from operating properly.
