2022 Kia Soul Owners Manual - Lane Keeping Assist (LKA) system

Lane Keeping Assist (LKA) system

Lane Keeping Assist (LKA) system detects the lane markers and road edge 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 or road, it alerts the driver with a visual and audible warning, while applying a countersteering torque, trying to prevent the vehicle from moving out of its lane or road.

WARNING

• Depending on the country in which the vehicle sold, departure warning and steer control of road edge function may not be available. See following table for details.
  
• Please contact your dealer to see if road-edge detection based features is available in your country.
• Driver is responsible for being aware of surroundings and steering the vehicle for safe driving practices.
• Do not steer the steering wheel suddenly when the steering wheel is being assisted by the system.
• LKA system helps prevent the driver from moving out of the lane or road 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 LKA system can be canceled or not work properly according to road condition and surroundings. Always be cautious when driving.
• Do not disassemble a front view camera temporarily for tinted window or attaching any types of coatings and accessories. If you disassemble the camera and assemble it again, have the system checked by a professional workshop. Kia recommends to visit an authorized Kia dealer/service partner and have the system checked to need a calibration.
• When you replace the windshield glass, front view camera or related parts of the steering, have the system checked by a professional workshop. Kia recommends to visit an authorized Kia dealer/ service partner and have the system checked to need a calibration.
• The system detects lane markers and road edge and controls the steering wheel by a front view camera, therefore, if the lane markers are hard to detect, the system may not work properly. Always be cautious when using the system.
• When the lane markers and road edge are hard to detect, please refer to “Driver's Attention” on page 6-103.
• Do not remove or damage the related parts of LKA system.
• Do not place objects on the crash pad that reflects light such as mirrors, white paper, etc. it may cause malfunction of LKA system if the sunlight is reflected.
• You may not hear warning sound of LKA system because of the excessive audio sound.
• While other beeps such as the seat belt warning sound are in operation and override LKA alarming system, LKA beeps may not occur.
• If the vehicle speed is high, steering torque for assistance will not be enough to keep your vehicle within the lane. If so, the vehicle may move out of its lane. Obey speed limit when using LKA system.
• If you attach objects to the steering wheel, the system may not assist steering.
• If you attach objects to the steering wheel, hands off alarm may not work properly.

LKA system operation

To activate/deactivate LKA:

With the engine start/stop button in the ON position, LKA turns on automatically. The indicator () in the cluster display will initially illuminate white. If you press the LKA button located on the instrument panel on the lower left hand side of the driver, LKA will be turned off and the indicator on the cluster display will go off.

The color of indicator will change depend on the condition of LKA.

- White : Sensor does not detect the lane marker or vehicle speed is less than 60 km/h (37 mph).
- Green : Sensor detects the lane marker or road edge and system is able to control the steering.

LKA system activation

• To see LKA system screen on the LCD display in the cluster, Tab to the ASSIST mode ( ).
• For further details, refer to [menu settings] in chapter 4, [crash pad].
• After LKA system is activated, if the lane marker or road edge are detected, vehicle speed is over 60 km/h (37 mph) and all the activation conditions are satisfied, a green steering wheel indicator will illuminate and the steering wheel will be controlled.

WARNING

Lane Keeping Assist System is a system to help prevent the driver from leaving the lane or road edge. However, the driver should not solely rely on the system but always check the road conditions when driving.

If the speed of the vehicle is over 60 km/h (37 mph) and the system detects lane markers, the color changes from gray to white.

Warning

If the vehicle leaves a lane or road edge, the lane marker or road edge you cross will blink on the LCD display and the warning sound is provided.

If the driver takes hands off the steering wheel for several seconds while LKA is activated, the system will warn the driver.

WARNING

• The warning message may appear late according to road conditions. Therefore, always have your hands on the steering wheel while driving.
• If you hold the steering wheel lightly, the system would generate hands off warning because LKA system can treat the situation as you do not grab the wheel.
• If continuous hands-off occurs continuously, the beeping can be lengthened and continued even if LKA steer control is released.

WARNING

• The driver is responsible for accurate steering.
• Even though the steering is assisted by the system, the driver may control the steering wheel.
• Turn off the system and drive the vehicle in below situations.
  - In bad weather.
  - In bad road condition.
  - When the steering wheel needs to be controlled by the driver frequently.
  - When towing a vehicle or trailer.
• The steering wheel may feel heavier when the steering wheel is assisted by the system than when it is not.

The system will be canceled 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 system can transit to steering assist mode when the car is near to middle of the lane after system on or the lane was changed. LKA system 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 your drive fast on a sharp curve.
• The steering will not be assisted when vehicle speed is below 55 km/h (34 mph) and over 200 km/h (125 mph).
• The steering will not be assisted when you change lanes or road edge fast.
• The steering will not be assisted when you brake suddenly.
• The steering will not be assisted when the lane is very wide or narrow.
• There are more than two lane markers such as a construction area.
• Radius of a curve is too small.
• When you turn steering wheel suddenly, the LKA system will be disabled temporarily.

LKA system function change

The driver can change LKA to Lane Departure Warning (LDW) or change LKA mode from the User Settings Mode on the LCD display.

Lane keeping assist

LKA mode guides the driver to keep the vehicle within the lanes. It rarely controls the steering wheel, when the vehicle drives well inside the lanes. However, it starts to control the steering wheel, when the vehicle is about to deviate from the lanes.

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 steering wheel will not be controlled. When the vehicle’s front wheel contacts the inside edge of lane line, LKA issues the lane departure warning.
