Warning system

Automatic Emergency Braking

Forward collision warning and automatic emergency braking share the same radar and camera, so when one complains, the other often does too. These are safety-critical systems, which is why a fault light deserves attention rather than a shrug. The good news is that most warnings trace back to something simple: a sensor caked in road grime, a bumper knocked slightly out of alignment, or condensation behind the grille emblem. This section breaks down what the pre-collision and AEB warnings mean across common brands, how to spot a false alert, and when a warning points to a genuine hardware problem. You will also find plain steps to clean, reset, and verify the system so you know it is ready when you need it most.
