Lane Departure Warning (LDW) - symbols and messages

Updated 08/06/2023

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.

In situations where there is no LDW function a symbol may be shown in the combined instrument panel in combination with an explanatory message - follow the recommendation given if appropriate.

Message examples:
