Learning More About Lane Keep Assist Dashboard Light

The LANE KEEP ASSIST, If you find yourself drifting out of your lane, this feature can assist you in getting back on track. This may be of use in preventing a crash.

If your vehicle is equipped with LKA, it may be able to prevent crashes caused by unintended lane exits. When traveling between 60 and 180 km/h (37 to mph), this technology employs a camera to detect lane markings (112 mph). If the car comes close to a detected lane marking, it may assist by gently shifting the steering wheel to the left or right. A Lane Departure Warning (LDW) signal may be issued if the vehicle passes over the center line of an observed lane marking. The LKA can be overridden by turning the steering wheel to the left or right. This device is not meant to maintain the vehicle’s center of gravity in the lane it is traveling in. It will not help and alert you if your turn signal is activated in the direction of lane departure, or if it detects you are accelerating, braking, or actively guiding the vehicle in that direction.

THE TECHNOLOGY THAT POWERS IT

The operation of this feature is dependent on the presence of painted lane lines. These comprise the markings between lanes as well as the lines that run along the sides of the road. It is possible that some versions of this technology will also aid in preventing you from going off the road.

WHAT YOU ARE REQUIRED TO DO

Always keep an eye on your surroundings and the traffic in the lanes around you when you are driving. If you do happen to drift out of your lane, you will notice a warning on your dashboard, hear a sound, or feel the vibrations in your seat or steering wheel as a result. This is the sound of your lane departure warning system going off. In the event that you fail to respond in time, lane keeping assist will gently steer you back to the center of the lane.

HOW IT WORKS

LKA detects lane markings with the use of a camera sensor that is mounted on the windshield just ahead of the rearview mirror. If it detects an unintentional lane departure, it may deliver a brief steering aid to compensate.
If a lane marking is crossed, it may also sound an auditory alert or the driver’s seat may pulse, signaling that the marking has been crossed.
Press the Lane keep assist button on the steering wheel to turn on and off LKA. When LKA is enabled, the indicator light on the button illuminates, and when  LKA is disabled, the indicator light on the button turns off.

When the system is turned on Lane keep assist , the l  is white if it is equipped, suggesting that the system is not ready to assist. If LKA is ready to assist, the Lane keep assist is green. If the vehicle is approaching a detected lane marking, LKA may be able to assist by gently shifting the steering wheel to the right. When aiding, the  Lane keep assist is amber. A Lane Departure Warning (LDW) signal may also be issued if the vehicle goes over a detected lane marking. This is shown by the flashing of Lane keep assist amber.

Additionally, depending on the direction of the lane departure, three beeps or three pulses from the driver’s seat may be heard on the right or left side of the dashboard.

WARNING USING THE LANE KEEP ASISST

The LKA system does not provide continuous steering assistance to the vehicle.
The vehicle may not maintain its lane position or provide a Lane Departure Warning (LDW) signal even if a lane marking is identified by the system.

It is possible that the LKA and LDW systems will not:

⚠️Provide an alarm or sufficient steering assistance to prevent a lane departure or a collision.

⚠️When the weather or visibility conditions are poor, it is important to detect lane markings. This can occur if the windshield or headlamps are obscured by dirt, snow, or ice, or if they are not in proper working order; it can also occur if the sun shines directly into the camera’s viewfinder.

⚠️ Identify the road’s edge.

⚠️On curving or hilly roads, keep an eye out for lanes.

As long as LKA only detects lane markings on one side of the road, it will only assist or issue an LDW alert when approaching the lane on the side of the road where the marking has been identified. Even when using LKA and LDW, you must maintain control of the car. Always keep your eyes on the road and your car in the proper lane position, or else serious vehicle damage, injury, or death could result from a collision. Ensure that the windscreen, headlamps, and camera sensors are kept clean and in good working order at all times. LKA should not be used in inclement weather or on highways with ambiguous lane lines, such as those in construction zones.

When towing a trailer or driving on slick roads, using LKA may result in the loss of control of the vehicle and a crash. Turn the system off if it is on.

When the System Doesn’t Work

The system performance may be affected by

⚠️Close up vehicles.

⚠️Sudden lighting changes, like in tunnels.

⚠️paved roads

⚠️Poorly marked two-lane roads.

Cleaning the windshield may help if the LKA system is not working properly when lane markings are visible.

If the camera is blocked, a message will appear. Some driver assistance systems may perform poorly or not at all. If the systems are temporarily unavailable, a LKA or LDW message will appear. A blocked camera may cause this message. The LKA system is fine. Clean the outside of the rearview mirror.

Tar marks, shadows, road cracks, temporary or construction lane markings, and other road imperfections can cause LKA and/or LDW alerts. This is normal system operation and the vehicle is fine. If this persists, turn off LKA.
