Lane Keeping Aid (LKA) - symbols and messages
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.
In situations where there is no LKA function or it is interrupted, a symbol may be shown in the combined instrument panel in combination with an explanatory message - follow the recommendation given if appropriate.
Message examples:
