Lane Keeping Aid (LKA) - operation

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.

Lane Keeping Aid is supplemented with self-explanatory graphics in different situations. Here are some examples:


LKA is temporarily deactivated for as long as the direction indicator is switched on.
P4-1420-LKA Tracking both sides
LKA "sees" and follows the side lines.

If Lane Keeping Aid is active and detects/"sees" the side lines, the LKA symbol indicates this with WHITE lines.

  • GREY side line - Lane Keeping Aid does not see a line on that side of the car.
P4-1220-LKA Intervention on right side
LKA intervenes on the right-hand side.

Lane Keeping Aid intervenes and steers away from the side line - this is indicated with:

  • RED line for the side in question.
