Lane Keeping Aid

Lane Keeping Aid (LKA) - function

עודכן 7/23/2018

Lane Keeping Aid is one of the functions in the Driver Alert System - sometimes also referred to as LKA (Lane Keeping Aid).

The function is intended for use on motorways and similar major roads in order to reduce the risk of the vehicle accidentally leaving its own lane in certain situations.

Certain settings can be made for the Lane Departure Warning function.

Off & On

Lane Keeping Aid is active within the speed interval 65-200 km/h on roads with clearly visible side lines. The function is temporarily deactivated on narrow roads with less than 2.6 metres between the lane's side lines.

Press the button in the centre console to activate or deactivate the function. The function is switched on if one lamp is illuminated in the button.

Some combinations of the selected equipment leave no vacant space for an Off/On button in the centre console - in which case the function is handled by the car's menu system MY CAR instead. For a description of the menu system, see MY CAR.

In addition, the following selections can be made in MY CAR:

  • Warning with vibration in the steering wheel: - On or Off.
  • Active steering: - On or Off.
  • Both, Warning with vibration in the steering wheel and Active steering: - On or Off.

Active steering

Lane Keeping Aid strives to keep the car within the side lines for the lane.

If the vehicle crosses a side line, Lane Keeping Aid warns the driver with pulsating vibration in the steering wheel. This occurs regardless of whether the car is actively steered back by applying a slight steering torque.

Dynamic cornering

LKA does not intervene in sharp inside bends.

In certain cases, Lane Keeping Aid allows the car to cross side lines without engaging active steering or warning with pulsating vibration in the steering wheel. Using an adjacent lane for dynamic cornering when there is a clear line of vision is an example of one such case.
