Hyundai Santa Fe (TM): Driving Safety / Lane Keeping Assist (LKA)

Lane Keeping Assist is designed to help detect lane markings (or road edges) while driving over a certain speed. The system will warn the driver if the vehicle leaves the lane without using the turn signal, or will automatically assist the driver’s steering to help prevent the vehicle from departing the lane.

Detecting sensor

[1] : Front view camera

The front view camera is used as a detecting sensor to detect lane markings (or road edges).

Refer to the picture above for the detailed location of the detecting sensor.

CAUTION

For more details on the precautions of the front view camera, refer to “Forward Collision-Avoidance Assist (FCA)” section in chapter 7.

Setting functions for the system

Lane Safety

With the engine on, select ‘Driver Assistance → Lane Safety’ from the Settings menu to set whether or not to use each function.

-- If ‘Assist’ is selected, the system will automatically assist the driver’s steering when lane departure is detected to help prevent the vehicle from moving out of its lane.
-- If 'Warning Only' is selected, the system will warn the driver with an audible warning when lane departure is detected. The driver must steer the vehicle.
-- If ‘Off’ is selected, the system will turn off. The indicator light will turn off on the cluster.

WARNING

• If 'Warning Only' is selected, steering is not assisted.
• Lane Keeping Assist does not control the steering wheel when the vehicle is driven in the middle of the lane.
• The driver should always be aware of the surroundings and steer the vehicle if ‘Off’ is selected.

System operation

System warning and control

Lane Keeping Assist will help warn and control the vehicle with Lane Departure Warning and Lane Keeping Assist.

Lane Departure Warning

• To warn the driver that the vehicle is departing from the projected lane in front, the green indicator light will blink on the cluster, the lane line will blink on the cluster depending on which direction the vehicle is veering, and an audible warning will sound.
• The system will operate when your vehicle speed is between approximately 40~120 mph (60~200 km/h).

Lane Keeping Assist

• To warn the driver that the vehicle is departing from the projected lane in front, the green indicator light will blink on the cluster, and the steering wheel will make adjustments to keep the vehicle inside the lane.
• The system will operate when your vehicle speed is between approximately 40~120 mph (60~200 km/h).

Hands-off warning

If the driver takes their hands off the steering wheel for several seconds, the ‘Place hands on the steering wheel’ (or ‘Keep hands on the steering wheel’) warning message will appear on the cluster, and an audible warning will sound in stages.

WARNING

• The steering wheel may not be assisted if the steering wheel is held very tight or the steering wheel is steered over a certain degree.
• Lane Keeping Assist does not operate at all times. It is the responsibility of the driver to safely steer the vehicle and to maintain the vehicle in its lane.
• The hands–off warning message may appear late depending on road conditions. Always have your hands on the steering wheel while driving.
• If the steering wheel is held very lightly, the hands–off warning message may appear because the system may not recognize that the driver has their hands on the steering wheel.
• If you attach objects to the steering wheel, the hands-off warning may not work properly.

Information

• You may change settings from the instrument cluster (User Settings) or infotainment system (Vehicle Settings), whichever option that is provided with your vehicle. For more details, see "User Settings" section in chapter 4, or "Vehicle Settings" section in supplied Infotainment Manual.
• When lane markings (or road edges) are detected, the lane lines on the cluster will change from grey to white and the green indicator light will illuminate.
  
• Even though the steering is assisted by Lane Keeping Assist, the driver may control the steering wheel.
• The steering wheel may feel heavier or lighter when the steering wheel is assisted by Lane Keeping Assist than when it is not.

System malfunction and limitations

System malfunction

When Lane Keeping Assist is not working properly, the ‘Check Lane Keeping Assist (LKA) system’ (or ‘Check LKA (Lane Keeping Assist) system’) warning message will appear and the yellow indicator light will illuminate on the cluster. If this occurs, we recommend that the system be inspected by an authorized HYUNDAI dealer.

Limitations of the system

Lane Keeping Assist may not operate normally or may operate unexpectedly under the following circumstances:

• The lane is contaminated or difficult to distinguish because,
  -- The lane markings (or road edge) is covered with rain, snow, dirt, oil, etc.
  -- The color of the lane marking (or road edge) is not distinguishable from the road
  -- There are markings (or road edges) on the road near the lane or the markings (or road edges) on the road looks similar to the lane markings (or road edge)
  -- The lane marking (or road edge) is indistinct or damaged
  -- The shadow is on the lane marking (or road edge) by a median strip, trees, guardrail, noise barriers, etc.
• There are more than two lane markings (or road edges) on the road
• The lane number increases or decreases, or the lane markings (or road edges) are crossing
• 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 zigzag lanes, crosswalk markings and road signs
• The lane suddenly disappears, such as at the intersection
• The lane (or road width) is very wide or narrow
• There is a road edge without a lane
• There is a boundary structure in the roadway, such as a tollgate, sidewalk, curb, etc.
• The distance to the front vehicle is extremely short or the vehicle in front is covering the lane marking (or road edge)
