Cameras, Radar and Sensors

Behind every driver-assist feature sits a small network of eyes: a forward camera near the mirror, radar hidden in the grille, ultrasonic sensors in the bumpers, and sometimes corner radars too. Cameras, Radar and Sensors explains what each one does, where it lives on your car, and what blinds it. Rain, road salt, a stone chip, a cheap windshield, even a slightly bent bracket can be enough to trigger a fault. We show you how to spot which sensor is unhappy, what a blocked or misaligned sensor looks like from the driver seat, and which problems you can solve with a microfiber cloth versus which ones need a technician. Know the hardware and the warning lights stop being a mystery.
