Lane Departure Warning (LDW) - operation

Lane Departure Warning is one of the functions in the Driver Alert System - sometimes also referred to as LDW (Lane Departure Warning).

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.

LDW is complemented in the combined instrument panel with intuitive graphics in different situations. Here are some examples:

The LDW function's side lines (marked in red in the figure).
  • The LDW symbol has WHITE side lines - the function is active and detects/"sees" one side line, or both.
  • The LDW symbol has GREY side lines - the function is active but detects neither left nor right side line.

or

  • The LDW symbol has GREY side lines - the function is in standby mode because the speed is below 65 km/h.
  • The LDW symbol has no side lines - the function is deactivated.
