Warning system

Lane Keep Assist

Lane keep assist watches the painted lines and nudges you back when the car drifts. It is one of the most common systems to throw a warning, and the reasons are rarely dramatic. A dirty windshield camera, faded road markings, or a recent battery disconnect can all set off the amber symbol. This section explains what the lane keeping, lane centering, and lane departure warnings actually mean on your dashboard. You will learn how to tell steering assist faults apart from simple camera obstructions, why the system switches off in snow or heavy rain, and what to check before you book a service appointment. Every guide here is written for drivers, not engineers, so you can act with confidence.
