NOTICE
 Do not install or place anything near the camera.
 Do not attach window tinting to the windshield.
 Do not install an antenna in front of the camera lens.
 When adjusting the rear view mirror, make sure that it does not block the
camera lens.
When it is cold, using the heater with air blowing to the feet may allow the

upper part of the windshield to fog up. This will have a negative effect on
the images. In such a case, use the windshield defogger to provide warm,
dry air to the windshield.
 Do not place anything on the dashboard.
The camera sensor may recognize the image reflected on the windshield
as lane markings by mistake.
 Do not scratch the camera lens, or let it get dirty.
 Do not change the installation position of the camera sensor or remove it.
The direction of the camera sensor is precisely adjusted.
 Do not subject the camera sensor to strong impact or force, and do not
disassemble the camera sensor.
Do not replace windshield with non-genuine windshield.

Contact any authorized Toyota dealer or repairer, or another duly qualified
and equipped professional.
