- When replacing the windshield glass equipped with the forward recognition camera, be sure to replace it with a genuine windshield glass for the forward recognition camera. A windshield glass other than a genuine windshield glass for the forward recognition camera does not have a camera installation bracket. Therefore, the forward recognition camera cannot be installed. If the forward recognition camera is mounted on a windshield glass that is not a genuine windshield glass for the forward recognition camera, the systems using the forward recognition camera may not operate properly because of the transmittance of the windshield glass and the shape of black ceramic parts.
