The lane keeping assist (LKA) system uses a front camera, front radar, and rear side radar to recognize lanes, pedestrians, and approaching vehicles from both the front and rear. It calculates the distance between the vehicle and the left/right lanes, as well as approaching vehicles, at speeds of 50 ~ 180 km/h to help maintain lane position.

If the vehicle drifts out of the lane or there is a collision risk with pedestrians or vehicles in adjacent lanes, the system provides braking assistance to prevent lane departure and avoid collisions, reminding the driver to stay within the lane. This system includes lane departure warning (LDW), lane keeping assist (LKA), and emergency lane keeping assist (ELKA).

When using this system, the driver must always keep both hands on the steering wheel.

This system should only be used on highways and urban arterial roads, and the driver must remain focused on driving.

While using this system, you should grip the steering wheel and pay attention to the road and surrounding traffic. Do not use this feature on urban roads, construction zones, narrow streets, or roads with bicycles or pedestrians. Do not rely on this system to determine the appropriate driving path. Always be prepared to take immediate action. Failure to follow these instructions may result in property damage, serious bodily injury, or death.

If the electronic stability control (ESC) is turned off, the lane keeping assist (LKA) and emergency lane keeping assist (ELKA) will not function.

■ Location of camera 1 and radars 2 and 3

This system uses a front camera 1, front radar 2, and side radar 3.

When the vehicle is powered on, the system begins a self-check, during which the system functions are not available.

Please ensure that the front camera and front/side radar areas are clean. Environmental conditions such as dirt in the areas where the system functions, rain, or faint lane markings can affect the system's performance. If there is a malfunction, related messages may appear on the instrument panel.

You can retake control of the vehicle at any time by operating the steering wheel.

■ Function types

  • Lane departure warning (LDW): The system alerts the driver when the vehicle unintentionally drifts out of its lane, including both already occurred and imminent lane departures.
  • Lane keeping assist (LKA): When the vehicle approaches the lane edge and is at risk of departing the lane, torque is applied to the steering wheel to help the driver regain control and steer the vehicle back into the lane.

    If you attempt to change lanes without activating the turn signal after the lanekeeping assist (LKA) is activated, torque may be applied to the steering wheel.

  • Emergency lane keeping assist (ELKA): Vehicles equipped with this system help the vehicle return to its original lane in the following situations:
    • When the vehicle is at risk of veering off the road or colliding with the edge of a crossable road.
    • When unintentionally drifting out of the lane poses a risk of collision with oncoming vehicles.
    • When unintentional lane departure presents a risk of collision with vehicles behind.
    • When unintentional lane departure poses a risk of collision with pedestrians in adjacent lanes.
warning

This system cannot handle all situations under every type of traffic, weather, and road conditions.

This system cannot detect roadside fences, guardrails, or similar obstacles.

The system is activated only in situations with a high risk of collision, so do not wait for this feature to intervene.

Drivers must always maintain attention and judgment to drive safely, keep a proper distance from other vehicles, and comply with current traffic laws.

■ Activation/deactivation

On the left menu of the central screen, select [My apps] -[Driver assistance]-[Active driver assist]-[Lane keeping assist]. From there, you can activate or deactivate [Lane keeping assist], [Lane departure warning], and [Emergency lane keeping assist]. (For [Lane departure warning], sound and vibration settings are available.)

Alternatively, you can swipe down from the top left of the central screen to select [Control center], then set [Lane keeping assist] to activate or deactivate the [Lane departure warning] function. You can also select [Control center] - [Lane departure warning] to activate or deactivate the [Lane departure warning] function. Multimedia equipment

When the lane departure warning (LDW) and lane keeping assist (LKA) functions are activated, the LKA indicator light on the instrument panel will illuminate in green.

The emergency lane keeping assist (ELKA) is automatically activated every time the vehicle is started. The lane departure warning (LDW) and lane keeping assist (LKA) will return to the settings from the previous start each time the vehicle is restarted.

You can interrupt the trajectory correction at any time by moving the steering wheel.

■ Operation

Due to the limitations of sensor performance, the curvature of the lane may be inaccurately detected (e.g., a straight road may be displayed as a curved road).

The lane keeping assist system displays information about the system's operating status on the instrument panel.

When the lane departure warning (LDW) or lane keeping assist (LKA) is activated, the lane keeping assist system indicator light 4 will illuminate in green. If there is a malfunction in the system, the indicator light will illuminate in yellow.

▶ Lane indicator light 5

The lane indicator light 5 will be displayed on the instrument panel depending on the following conditions:

  • Not displayed: The system cannot detect the lane.
  • Gray: The system is not activated.
  • White: The system is in standby mode.
  • Red: The system is active.
  • Blue: The system has intervened by applying torque to the steering wheel.

■ "Keep control" Warning

When the lane keeping assist system is activated, the driver must always keep both hands on the steering wheel. If the system does not detect hands on the steering wheel when it is first activated, no alert message will be displayed on the instrument panel. If hands are not detected again after the system is reactivated, the system will issue a warning sound and display a message on the instrument panel saying "Please hold the steering wheel."

Once both hands are detected, the alert displayed on the instrument panel will disappear, and the system will continue to operate.

Issues such as abnormal tyre pressure, four-wheel drive alignment errors, mismatched tyres, or non-standard tyres can lead to abnormal system performance. The driver should only use this system when the vehicle is in normal condition.

warning

This function is an additional driving aid. This function is not under any circumstances intended to replace the due care and attention of the driver, who should at all times be in control of the vehicle.

System servicing/repairs

  • In the event of an impact, the camera alignment may be changed, and its operation may consequently be affected. Deactivate the function and consult an authorised dealer.
  • Any work in the area where the camera is located (repairs, replacements, windscreen modifications etc.) must be carried out by a qualified professional. Only an authorised dealer is qualified to service the system.

In the event of system disturbance

Some conditions can disturb or damage the system's operation, such as:

  • windscreen obscured (by dirt, ice, snow, condensation etc.);
  • a complex environment (tunnel, etc.);
  • poor weather conditions (snow, rain, hail, black ice, etc.);
  • Poor visibility (night, fog, etc.);
  • the road markings are irregular or difficult to distinguish (e.g. partially erased, excessive spacing, distorted road surface...);
  • there are out-of-lane markings or lane-like markings around the lane; or shadows from objects around the road, such as medians, guardrails, noise barriers, or surrounding vegetation, obscure the lane.
  • being dazzled (glaring sun, lights of vehicles travelling in the opposite direction; etc.);
  • the road is narrow, winding or undulating (tight bends, etc.);
  • closely following a vehicle travelling in the same lane.

In this case, the system might react incorrectly or not react at all.

Risk of unwanted, incorrect correction or no correction of trajectory.

Deactivating the function

You must deactivate the function if:

  • the area of the camera has been damaged (on the windscreen side or the interior rear-view mirror side);
  • the road is slippery (snow, black ice, aquaplaning, gravel, etc.);
  • Poor visibility (night, fog, etc.);
  • the windscreen is cracked or distorted (do not carry out windscreen repairs in this area; have it changed by an approved dealer);
  • the vehicle is towing a trailer or a caravan;
  • the vehicle is entering an area with several surface markings (an area with road works etc.);
  • If you randomly apply force to one side of the steering wheel and release both hands at the same time.

■ System limitations

The following road conditions can reduce system performance or make it inoperable. The driver must remain alert at all times.

  • The system cannot be applied on roads with excessively small curve radii.
  • The system is not applicable on roads where lanes are not visible.
  • The system cannot be applied at intersections.
  • The system does not apply to roads with vehicle markings (e.g., tyre tracks).
  • The system does not apply to roads where lanes are increasing or decreasing.
  • The system does not apply to roads with large differences between existing and new lanes.
  • The system does not apply to pavements with potholes, unevenness, or irregularities.
  • The system cannot recognize road markings (cones), so it does not apply to pavements under construction.
  • The system does not work on ultra-wide/ultra-narrow roads.
  • The system does not work on zigzag pavements.
  • The system does not apply when visibility is reduced due to inclement weather.
  • The view of the front camera, front radar, and blind spot radar must not be obstructed by contaminants. The system shuts down, especially when completely covered by snow, and shutdown information is displayed to the driver on the instrument panel.
  • The installation of the front camera, front radar, and blind spot radar may be subject to vibration or shock, which can degrade system performance. At this time, the front camera, front radar, and blind spot radar must be recalibrated.
