Lane Keeping Assist (LKA) system
The Lane Keeping Assist system is designed to detect the lane markers on the road with a front view camera at the front windshield, and assists the driver’s steering to help keep the vehicle in the lanes.
When the system detects the vehicle straying from its lane, it alerts the driver with a visual and audible warning, while applying a slight countersteering torque, in an attempt to prevent the vehicle form moving out of its lane.
WARNING
The Lane Keeping Assist System is a supplemental system and is not a substitute for safe driving practices. It is the responsibility of the driver to always pay attention and drive safely.
WARNING
- The driver is responsible for being aware of surroundings and steering the vehicle while employing safe driving practices.
- Do not steer the steering wheel suddenly when the steering wheel is being assisted by the system.
✽ NOTICE
- LKA helps prevent the driver from moving out of the lane unintentionally by assisting the driver’s steering. However, the system is just a convenience function and the steering wheel is not always controlled. While driving, the driver should pay attention to the steering wheel.
- The operation of the LKA can be cancelled or not work properly because of road conditions and the surroundings. Always be cautious when driving.
- Do not disassemble the front view camera when installing tint on the windows or applying any type of coatings or accessories. If you disassemble the camera and assemble it again, take your vehicle to an authorized Kia dealer and have the system checked to need a calibration.
- When you replace the windshield glass, front view camera or system, take your vehicle to an authorized Kia dealer and have the system check to see if you need a calibration.
- The system is designed to detect lane markers using a front view camera. If the lane markers are hard to detect, then the system may be limited. Always be cautious when using the system.
- When the lane markers are hard to detect, please refer to the “Driver’s Attention” section in this Chapter
- Do not remove or damage the related parts of LKA.
- Do not place objects on the dashboard that reflect light such as mirrors, white paper, etc. This may prevent the system from functioning.
- If the audio sound is excessive, you may not hear the warning sound of the LKA.
- If you continue to drive with your hands off the steering wheel, the LKA system will stop controlling the steering wheel after the hands off alarm. Afterwards, if you drive with your hands on the steering wheel, the control will be activated again.
- At high vehicle speeds, the steering torque of LKA may not be enough to keep your vehicle within the lane. If so, the vehicle may move out of its lane. Therefore, obey any applicable speed limits when using LKA.
- If you attach objects to the steering wheel, the system may not assist steering.
- If you attach objects to the steering wheel, the hands off alarm may not work properly.
LKA operation
To activate/deactivate the LKA:
With the ignition switch in the ON position, press the LKA button located on the instrument panel on the lower left hand side of the driver.
The indicator in the cluster display will initially illuminate white.
When the indicator(white) activated in the previous ignition cycle, the system turns on without any control.
If you press the LKA button again, the indicator on the cluster display will go off.
The color of the indicator will change depend on the condition of LKA.
- White : Sensor does not detect the lane marker or vehicle speed is less than 64 km/h (40 mph).
- Green : Sensor detects the lane marker and system is able to control the steering.
LKA activation
- To see the LKA screen on the LCD display in the cluster, Tab to the ASSIST mode (
). - For further details, refer to the [menu settings] section in Chapter 4.
- After LKA is activated, if both lane markers are detected, vehicle speed is over 64 km/h (40 mph) and all the activation conditions are satisfied, a green steering wheel indicator will illuminate, and the steering wheel will be controlled.
WARNING
The Lane Keeping Assist system is a system to help prevent the driver from leaving the lane. However, the driver should not rely solely on the system and should always check the road conditions while driving.
If the speed of the vehicle is over 64 km/h (40 mph) and the system detects lane markers, the color changes from gray to white
When the conditions below are met, LKA will be enabled to assist steering.
- Vehicle speed is above 64 km/h (40 mph).
- Both lane markers are detected by LKA.
- The vehicle is between the lane markers.
If LKA can assist steering, a green steering wheel indicator will illuminate.
Warning
If the vehicle leaves a lane, the lane marker you cross will blink on the LCD display.
If the vehicle moves out of its lane because the steering torque for assistance is insufficient, the line indicator will blink.
• If all the conditions to activate LKA are not satisfied, the system will convert to Lane Departure Warning (LDW) and only warn the driver when the driver crosses the lane markers. In this scenario, the LDW system does not provide any steering inputs to the vehicle for you. Accordingly, you must take the necessary steps to maintain control of the vehicle and keep it within the lanes.
If the driver takes hands off the steering wheel for several seconds while the LKA is activated, the system will warn the driver.
WARNING
- Always keep your hands on the steering wheel while driving.
- If you hold the steering wheel with a light grip, the system may also generate the hands off warning because LKA can treat the situation as you not OBD058111R grabbing the wheel.
If the driver still does not have their hands on the steering wheel after several seconds, the system will only warn the driver when the driver crosses the lane lines. In this scenario, the system does not provide any steering inputs to the vehicle for you. Accordingly, you must take the necessary steps to maintain control of the vehicle and keep it within the lanes.
However, once the driver has their hands on the steering wheel again, the system will again provide steering inputs if it detects the vehicle leaving the lane.
WARNING
- The LKA system is a supplemental system only. It is the responsibility of the driver to safely steer the vehicle and to maintain it in its lane
- Even though the steering is assisted by the system, the driver may control the steering wheel.
- Turn off the LKA system and drive without the use of the system in the following situations:
- In bad weather
- In bad road conditions
- When the steering wheel needs to be controlled by the driver frequently. - The steering wheel may feel heavier when the steering wheel is assisted by the system than when it is not.
✽ NOTICE
- Even though the steering is assisted by the system, the driver may control the steering.
- The steering wheel may feel heavier when the steering wheel is assisted by the system than when it is not.
The system will be cancelled when:
- You change lanes with the turn signal.
- Using the turn signal to change lanes.
- If you change lanes without the turn signal on, the steering wheel might be controlled. - LKA can transition to steering assist mode when the car is near the middle of the lane after the system is turned on or the lane was changed. LKA can not assist steering if the vehicle follows lane marker too close continuously before transition to steering assist mode.
- The control of ESC (Electronic Stability Control) or VSM (Vehicle Stability Management) is activated.
- The steering will not be assisted when you drive fast on a sharp curve.
- The steering will not be assisted when vehicle speed is below 64 km/h (40 mph) and over 177 km/h (110 mph). Always obey all traffic laws and drive safely.
- The steering will not be assisted when you change lanes quickly.
- The steering will not be assisted when you brake suddenly.
- The steering will not be assisted when the lane is very wide or narrow.
- The steering will not be assisted when only one side lane marker is detected.
- There are more than two lane markers such as a construction area.
- Radius of a curve is too small.
- When you turn the steering wheel suddenly, the LKA will be disabled temporarily.
- Driving on a steep slope or hill.
DRIVER’S ATTENTION
The driver must be cautious in the following situations. LKA may not work properly when recognition of the lane markers is poor or limited:
• When lane and road condition are poor
- It is difficult to distinguish the lane marker from the road, such as when the lane marker is covered with dust or sand.
- It is difficult to distinguish the color of the lane marker from the road.
- There is something that looks like a lane marker.
- The lane marker is indistinct or damaged.
- The number of lanes increases/ decreases or the lane lines are crossing (Driving through a toll plaza/toll gate, merged/divided lane).
- There are more than two lane markers.
- The lane marker is very thick or thin.
- The lane marker is not visible due to snow, rain, stain, a puddle or other factors.

- There are crosswalk signs or other symbols on the road.
- The lane suddenly disappears such as at an intersection.
- The lane marker in a tunnel is covered with dirt or oil, etc.
• When external conditions interfere
- The brightness changes suddenly when entering/exiting a tunnel or passing under a bridge.
- The headlamps are not on at night or in a tunnel, or the light level is low.
- There is a boundary structure in the roadway.
- The light from a street lamp, sun, oncoming vehicle, etc. reflects off water on the road.
- When light shines brightly from behind the vehicle.
- The distance from the vehicle ahead is very short or the vehicle ahead covers up the lane line.
- You drive on a steep grade or a sharp curve.
- The vehicle vibrates heavily.
- The temperature near the inside mirror is very high due to direct sun light and etc.
• When front visibility is poor
- The lens or windshield is covered by foreign materials.
- The sensor cannot detect the lane because of fog, heavy rain or snow.
- The windshield is fogged by humid air in the vehicle.
- There is an object on the dashboard that interferes with the camera.
WARNING
The Lane Keeping Assist system is a system to help prevent the driver from leaving the lane. However, the driver should not rely solely on the system and should always take necessary actions to ensure safe driving practices.
LKA malfunction
■ Type A
■ Type B
• If there is a problem with the system, a message will appear. If the problem continues, the LKA fail indicator will illuminate.
LKA fail indicator
The LKA fail indicator (yellow) will illuminate with an audible warning if the LKA is not working properly. If this occurs have the system checked by an authorized Kia dealer.
When there is a problem with the system, do one of the following:
- Turn the system on after turning the engine off and on again.
- Check if the ignition switch is in the ON position.
- Check if the system is affected by the weather. (ex: fog, heavy rain, etc.)
- Check if there is foreign matter on the camera lens
If the problem is not solved, take your vehicle to an authorized Kia dealer and have the system checked.
LKA function change
The driver can change LKA to Lane Departure Warning (LDW) system or change the LKA mode between Standard LKA and Active LKA from the User Settings Mode on the LCD display.
The driver can choose the mode by placing the ignition switch to the ON position and by selecting ‘User Settings’, ‘Driver Assistance’, and ‘Lane Safety’.
The system is automatically set to Standard LKA when your vehicle is first delivered from the factory.
Lane Departure Warning
LDW alerts the driver with a visual and acoustic warning when the system detects the vehicle leaving the lane. In this mode, the system will not provide steering inputs. When the vehicle’s front wheel contacts the inside edge of the lane, LKA issues the lane departure warning.
Standard LKA
The Standard LKA mode guides the driver to keep the vehicle within the lanes. It provides inputs to the steering when the vehicle is about to deviate from the lanes.
Active LKA
The active LKA mode provides more frequent steering wheel control in comparison with the Standard LKA mode. Active LKA can reduce the driver’s fatigue by assisting the steering to help maintain the vehicle in the middle of the lane.
