- NOTICE:
- *1: Camera detection malfunctions can be detected using the intelligent tester. Under the following conditions, if the camera built into the inner rear view mirror assembly cannot detect other vehicles or lights correctly, it will stop automatic high beam control and turn off the automatic high beam indicator light:
- When the front windshield is not clear (ice, snow or frost is on the glass).
- When the front windshield is dirty (sand, mud, water stains or bugs are on the glass).
- When there is a seal or sticker, etc., on the front windshield near the automatic high beam sensor.
- *2: Aiming misalignment of the camera can be detected using the intelligent tester. Under the following conditions, the camera built into the rear view mirror assembly cannot adjust its center point:
- When the inner rear view mirror assembly is at an angle due to incorrect installation or damage to the camera.
- When the automatic aiming adjusting function of the mirror does not work correctly.
- If the camera aiming is misaligned, check the following conditions:
- Check if the vehicle is inclined.
- Check if the windshield glass is installed correctly.
- Check if the inner rear view mirror assembly is installed correctly.
- Check if there is deformation of the camera or stay of the inner rear view mirror assembly.
