F01 KAFAS
A warning is output only once on approach to a roadway marking. The warning lasts a
maximum of 2.5s. No more warnings are output if the vehicle then continues to drive
along the lane marking.
A new warning can only be issued if the vehicle has been steered back into the lane or
the vehicle has completed a change of lane.
No warning is given if the control unit has received an input signal indicating the activation
of the turn signals because this signal announces that the driver is about to change lane
intentionally.
Similarly, no warning is given if the hazard warning lights are switched on.
The warning ends when:
• The driver steers back into the lane
• A lane change is completed
• The vehicle drives along the line for longer than 2.5 seconds
• The turn signal is operated to indicate a change of lane
• The brake pedal is depressed with force (brake-pressure-dependent).
