Lane Keeping Aid (LKA) - function
Off & On
Lane Keeping Aid is active within the speed range 65-200 km/h (40-125 mph) 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 centre console's button to activate or deactivate the function. The button's lamp illuminates when the function is switched on.
Some combinations of the selected equipment leave no vacant space for an On/Off button in the centre console - in which case the function is instead handled in the car's menu system MY CAR. 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: Vibration only - On or Off.
- Active steering: Steering assist only- On or Off.
- Both Warning with vibration in the steering wheel and Active steering: Full function - On or Off.
Lane Keeping Aid strives to keep the car within the side lines for the lane.
If the car approaches the left or right side line of the lane and the direction indicator is not activated, the car is steered back into the lane.
Warning with vibration in steering wheel
If the car crosses a side line then Lane Keeping Aid will alert the driver with vibration in the steering wheel2. This occurs regardless of whether the car is actively steered back by applying a slight steering torque.
In certain cases Lane assistance will allow the car to cross lane lines without engaging active steering or activating a warning. Using an adjacent lane for cutting a corner when there is a clear line of vision is an example of this.
